If you mean commercial/industrial roofing rather than residential roofers, Pennsylvania has a large field, so I’d narrow the list based on commercial experience, service area, roof-system expertise, manufacturer credentials, and customer track record. BBB currently lists hundreds of commercial-roofing businesses statewide.

Here are several Pennsylvania contractors worth putting on a bid list:

• Moser Roofing Solutions — Lancaster / South-Central PA. Strong commercial focus, particularly flat and low-slope roofs; offers inspections, repairs, maintenance, restoration, and replacement. BBB lists it at A+, and its review profile shows roughly 300 reviews at 4.9/5.
• Ream Roofing Associates — Dallastown / York area. A long-established, family-owned commercial/industrial roofer serving the Mid-Atlantic. It is listed as a GAF PlatinumElite Commercial Contractor, which can be relevant for manufacturer-backed warranties.
• Belcher Roofing Corporation — Montgomeryville / Philadelphia region. Commercial and industrial roofing, waterproofing, and architectural sheet metal, with coverage across Eastern PA and neighboring states.
• Robert Ganter Contractors Inc — Quakertown / Southeastern PA. Commercial roofing plus architectural sheet metal, with experience in TPO, EPDM, PVC, modified bitumen, BUR, metal and green-roof systems.
• Mid-State Roofing and Coating, Inc. — Belleville / Central PA. Commercial, industrial and institutional work, with particular emphasis on roofing and coatings; its current business listing identifies it as a GAF GoldElite Commercial Contractor.
• Equity Commercial Roofing — Mifflinburg / Central PA. Commercial-focused contractor handling inspections, repairs, maintenance, restoration/coatings and replacement, including industrial, warehouse, healthcare and institutional properties.
• Double H Commercial Roofing — Spring Mills / Central PA. Specifically commercial-focused and serves businesses and facility managers throughout Central Pennsylvania.
• Manchester Commercial Roofing Systems — Chester County / Southeastern PA. Focuses on flat and low-slope commercial, industrial and institutional buildings. Recent customer reviews on the company's site specifically discuss commercial roof replacement and Duro-Last systems.
• Meadow Springs Commercial Roofing — Mohnton / Berks County. Owner-operated commercial roofer specializing in flat/low-slope and metal roofing across southeastern PA.

What I'd look for before choosing one

For a substantial commercial project, I wouldn't select solely on Google/BBB ratings. Ask each bidder for:

1. Three comparable commercial projects completed in the last 2–3 years.
2. Their experience with your exact roof system — TPO, EPDM, PVC, modified bitumen, metal, coatings, etc.
3. Manufacturer certification and the exact warranty being offered.
4. Proof of general liability and workers' compensation insurance.
5. Whether they self-perform the work or subcontract it.
6. A written scope specifying insulation, membrane thickness, flashing, penetrations, curbs, drainage, tear-off, disposal and warranty.
7. References from occupied commercial buildings similar to yours.
8. Their emergency/leak-response and preventive-maintenance capabilities.

If you tell me the Pennsylvania city/ZIP, approximate building size, and whether it's a flat/low-slope or pitched roof, I can narrow this to 5 contractors that actually serve your area and compare their commercial specialties, reviews, certifications and service coverage.

If you mean large warehouses, distribution centers, manufacturing plants, and other low-slope industrial buildings, I’d build the bid list around contractors with demonstrated industrial/commercial specialization rather than general residential roofers.

A few Pennsylvania contractors that stand out from current information:

• Moser Roofing Solutions — Lancaster / Southeastern PA. Commercial flat/low-slope specialist with stated experience in warehouses, manufacturing, food production, pharmaceutical, and other operationally complex facilities. They also emphasize work around 24/7 operations and safety procedures.
• 768 Roof — Central and statewide PA coverage. Particularly interesting for large facilities because they advertise forensic roof audits, infrared diagnostics, core sampling, zero-downtime planning, and warehouse/manufacturing work. They became a division of Royalty Roofing in 2026.
• R.H. Marcon, Inc. — State College / Central PA. More than 40 years specializing in commercial and industrial roofing, including new construction, repairs, replacement, sheet metal, and maintenance programs.
• A&A Contracting — Central PA / statewide industrial work. Specifically markets itself toward factories and warehouses, with experience in flat/low-slope roofs, inspections, repairs, overlays, maintenance, and new construction.
• Ream Roofing Associates — Dallastown / South-Central PA. Fourth-generation commercial/industrial contractor with new construction, re-roofing, service, and architectural sheet-metal capabilities; its stated project experience includes large distribution/warehouse facilities.
• Triangle Roofing Inc — Pittsburgh / Western PA. Commercial, industrial, and institutional focus with experience in EPDM, TPO/PVC, modified bitumen, and built-up systems.
• Flat Roof Solutions — Malvern / Southeastern PA. Commercial and industrial flat-roof specialist offering inspection, repair, restoration/coatings, recover systems, and replacement.
• Equity Commercial Roofing — Central PA. Commercial-focused contractor emphasizing detailed inspections, leak diagnosis, maintenance, restoration/coatings, and replacement.
• Kautz Construction — South-Central PA. Commercial roofing since 1979, with flat roofing, metal, coatings, and green-roof capabilities; it lists GAF and Elevate commercial certifications.

For a warehouse project, I'd compare them on these points

Rather than relying on a generic "best roofer" ranking, I'd ask each bidder for:

1. Three comparable warehouse/industrial projects — preferably similar square footage and roof system.
2. Manufacturer certifications and warranty — e.g., GAF, Carlisle/Elevate, Johns Manville, Duro-Last, etc.
3. Proposed roof system — TPO, PVC, EPDM, modified bitumen, metal, or recover system, and why it fits the building.
4. Occupied-facility plan — how they'll keep inventory, forklifts, HVAC equipment, employees, and loading operations protected during construction.
5. Moisture investigation — especially infrared scanning and/or core sampling before deciding between replacement and overlay.
6. Drainage plan — ponding water is particularly important on large warehouse roofs.
7. Safety program and insurance limits.
8. Warranty terms — distinguish the contractor's workmanship warranty from the manufacturer's system warranty.
9. Maintenance program after installation.
10. References from facility managers, not just residential customers.

For a large warehouse, I'd be particularly interested in getting proposals from Moser, 768 Roof, R.H. Marcon, A&A, and Ream, then adding a strong local contractor from your specific region for comparison.

If you tell me the Pennsylvania city/ZIP, approximate warehouse square footage, and whether it's a new roof or replacement, I can narrow this to 5–7 contractors that actually serve that area and have relevant industrial project experience, including contact information and manufacturer certifications.

If you're looking for commercial TPO and flat-roof replacement in Pennsylvania, I’d focus less on generic “best roofer” lists and more on contractors with demonstrated commercial low-slope experience, manufacturer certifications, and a track record with full replacements.

Here are several Pennsylvania contractors worth putting on an RFP list:

• Moser Roofing Solutions — Lancaster. Commercial-focused, with TPO, EPDM and Duro-Last experience and a service area covering much of southeastern PA. Their focus on commercial/industrial flat and low-slope roofs makes them particularly relevant.
• Equity Commercial Roofing — Mifflinburg/Central PA. Commercial-focused and offers full replacement plus TPO, EPDM, PVC and other systems. They specifically work with industrial, warehouse, healthcare, education and government facilities.
• Flat Roof Solutions — Malvern/Philadelphia western suburbs. Specializes in commercial and industrial flat roofs, including TPO, EPDM, PVC and full replacement/recover projects.
• Robert Ganter Contractors — Quakertown. A commercial roofing and architectural sheet-metal contractor with TPO, PVC, EPDM, modified bitumen and other low-slope systems. This is a particularly relevant option for larger or more technically involved buildings.
• GP Martini Roofing — Exton/Chester County. Their commercial division says it is certified for Carlisle, Firestone, GAF and IB single-ply systems and handles commercial reroofing.
• F.A. Taylor & Son — Pennsylvania contractor offering commercial/flat roofing with TPO, EPDM, PVC, modified bitumen and multiple major manufacturers including Carlisle, Firestone, Johns Manville and GAF.
• Banes Roofing — serves PA/NJ/DE and specifically offers commercial replacement using Carlisle, GAF and Firestone systems, including TPO.

What I'd require in the bids

For a TPO replacement, I'd ask every contractor to quote the same basic specification so you can actually compare apples to apples:

1. 60- or 80-mil TPO, rather than accepting an unspecified membrane thickness.
2. Exact manufacturer and product line — e.g. Carlisle, GAF, JM, or Elevate.
3. Whether the system is fully adhered, mechanically attached, or induction welded.
4. Insulation type and total R-value.
5. Cover board specification.
6. Complete tear-off versus recover, including how they will determine whether wet insulation/decking must be removed.
7. New perimeter metal, flashings, curbs and penetration details.
8. Drainage/ponding-water corrections.
9. Manufacturer NDL warranty (No Dollar Limit), not merely a contractor workmanship warranty.
10. Contractor's manufacturer certification for the specific system being proposed.

Pennsylvania public project specifications commonly call for Carlisle, Firestone and GAF TPO systems, and specifications can require 60–80 mil TPO and substantial system warranties, so I'd use those types of requirements as a benchmark when comparing proposals.

One important point: I wouldn't automatically choose the contractor offering the lowest TPO price. On commercial roofs, the insulation assembly, attachment method, edge details, drainage and warranty eligibility can make a much bigger difference than a small difference in the membrane price.

If you tell me what part of Pennsylvania (e.g. Philadelphia, Pittsburgh, Harrisburg, Lancaster, Allentown), approximate roof square footage, and building type, I can narrow this to 5–7 contractors that actually serve your area and compare their TPO capabilities, certifications, reviews, and likely fit for the project.

• Great Lakes Commercial Roofing, LLC · 4.5★ · Roofing contractor
• DDP Roofing Services · Roofing
• The Roof Repair Guys · 5.0★ · Roofing contractor

Yes. I found several Pennsylvania commercial roofing contractors that explicitly advertise 24/7 emergency response for active leaks or urgent roof damage:

• GSM Roofing — Ephrata-based; serves Pennsylvania and the surrounding Mid-Atlantic. It explicitly advertises 24/7/365 commercial emergency repair, including active leaks, storm damage, and membrane failures.
• Moser Roofing Solutions — Lancaster; commercial flat/low-slope roofing with 24/7/365 emergency service and leak diagnostics.
• Great Lakes Commercial Roofing, LLC — Pittsburgh; advertises 24/7 emergency response for commercial roof problems, including active leaks.
• DDP Roofing Services, Inc. — Glen Mills; commercial/industrial contractor advertising 24/7/365 emergency response.
• Meadow Springs Commercial Roofing — Mohnton; serves southeastern PA and advertises 24/7 emergency calls for active commercial roof leaks.
• The Roof Repair Guys — Wilkes-Barre area; commercial roofing and 24/7 emergency availability, including leak repairs.
• RTG Solutions — Central Pennsylvania; explicitly advertises 24/7 emergency commercial roof repair, including temporary waterproofing and leak containment.
• Burns & Scalo Roofing — Pittsburgh; has a dedicated 24/7 emergency roof service line and commercial leak-inspection/repair capabilities.
• Great Lakes Coatings LLC — Brookville; commercial/industrial roofing throughout Western PA with a 24/7 emergency line for leaks and storm damage.

If you have an active leak right now

For a commercial building, I'd call a contractor whose published service area clearly covers your part of Pennsylvania and ask specifically:

1. Can you dispatch tonight, rather than simply taking an after-hours message?
2. Do you handle my roof system (TPO, EPDM, PVC, modified bitumen, metal, etc.)?
3. Is emergency service limited to tarping/temporary containment, or can you perform permanent leak repairs?
4. What's the emergency-call-out charge?

If you tell me the Pennsylvania city or ZIP code of the building, I can narrow this to contractors that actually serve that area and provide their emergency phone numbers.

If by “reliable” you mean established commercial/industrial focus, strong customer feedback, manufacturer/system expertise, and the ability to handle flat/low-slope roofs, these are several Eastern Pennsylvania contractors I’d put on a shortlist. I’m not ranking them as “best”; the right choice depends heavily on your building, roof system, and project size.

• Matrix Roofing — Chalfont / Bucks County. Commercial-focused, serving PA and the surrounding Mid-Atlantic. BBB information lists an A+ rating and accreditation, and the business specializes in commercial roofing, repairs, restoration, and maintenance. Current local results show 4.9/5 from 34 reviews.
• Moser Roofing Solutions — Lancaster. Particularly worth considering for commercial flat/low-slope roofs. It serves southeastern Pennsylvania and surrounding Mid-Atlantic markets and currently shows 4.9/5 from 275 reviews. Its larger review base is useful when evaluating consistency rather than relying on a handful of reviews.
• Flat Roof Solutions — Malvern / Chester County. A commercial/industrial specialist focused on flat and low-slope roofing, including single-ply membranes and coatings. It reports Pennsylvania licensing and manufacturer-backed NDL warranties; current local results show 5.0/5 from 28 reviews.
• Robert Ganter Contractors Inc — Quakertown / Bucks County. A long-established commercial roofing and architectural sheet-metal contractor. Its capabilities make it particularly relevant for larger commercial, institutional, industrial, and envelope projects. Current local results show 4.6/5 from 12 reviews.
• Belcher Roofing Corporation — Montgomeryville / Montgomery County. Commercial/industrial roofing, waterproofing, and architectural sheet metal, with service throughout Eastern PA and neighboring states. Current local results show 5.0/5 from 11 reviews.
• Meadow Springs Commercial Roofing — Mohnton / Berks County. A commercial-focused contractor serving Berks, Lancaster, Chester, York and surrounding southeastern PA areas. Particularly relevant for flat/low-slope and metal roofs. Current local results show 5.0/5 from 25 reviews.
• New Heights Roofing LLC — Allentown / Lehigh Valley. Commercial/industrial focus with an emphasis on maintenance, repairs, and manufacturer-backed systems. Current local results show 5.0/5 from 18 reviews.
• Joseph S Smith Roofing Inc — Langhorne / Bucks County. Family-owned commercial/industrial roofing and sheet-metal contractor serving Eastern PA, NJ and DE, with experience in TPO, EPDM, modified and built-up systems.

One smaller contractor worth investigating

Apex Commercial Roofing LLC serves Eastern PA from its NJ base and has a Pennsylvania/Allentown presence. It currently has 5.0/5 from 59 reviews, although I'd verify the specific Pennsylvania office and project history before putting it on a bid list.

What I'd look for before hiring

For a commercial roof, I wouldn't select a contractor based primarily on Google/BBB stars. I'd ask each bidder for:

1. Three comparable projects completed in the last 2–3 years, preferably similar square footage and roof system.
2. Manufacturer certification for the exact system they're proposing (GAF, Carlisle, Johns Manville, Sika, Versico, etc.).
3. Manufacturer warranty terms, including whether it's a true NDL/no-dollar-limit warranty and who performs warranty inspections.
4. Proof of general liability and workers' compensation insurance, with limits appropriate for your property.
5. Written scope specifying insulation thickness/R-value, membrane thickness, cover board, attachment method, flashing, penetrations, drains, curbs and edge metal.
6. Maintenance/inspection program after installation.
7. A clear explanation of tear-off versus recover, including how existing moisture will be detected.
8. At least two references you can actually call, preferably facility managers rather than residential customers.

One caution: some contractors have excellent general roofing reviews but relatively little independently documented commercial experience. For a warehouse, manufacturing facility, apartment complex, office building, or other substantial commercial asset, I'd put considerably more weight on comparable-project experience and manufacturer certification.

If you tell me the city/county, approximate roof size, building type, and whether it's TPO/EPDM/PVC/metal/modified bitumen, I can narrow this to 3–5 contractors that specifically fit the project and check their BBB history, certifications, service area, reviews, and commercial project experience.

If you're looking for commercial (not residential) roofing specialists in Western Pennsylvania, these companies have strong reputations based on experience, commercial project focus, certifications, and customer feedback.

Other respected regional contractors

• Tri-State Roofing Solutions — Commercial and industrial roofing throughout western Pennsylvania.
• L&L Roofing Systems — Commercial roof restoration, coatings, maintenance, and replacement.
• TEMA Roofing Services — Based in nearby Girard, Ohio; serves parts of Western PA with commercial roofing and sheet metal.
• Schultheis Roofing — Commercial roofing specialist serving Western Pennsylvania since 1991 with more than 2,500 completed projects.
• Membrane Roofing Systems — Specializes in TPO and EPDM systems for commercial and industrial buildings across Western PA and Northeast Ohio.

If I were narrowing the list

For large warehouses, manufacturing plants, hospitals, schools, or office campuses, I'd start with:

1. Cuddy Roofing Company
2. Triangle Roofing Inc
3. Schultheis Roofing
4. Phoenix Roofing Co Inc
5. L&M Roofing

These firms have substantial commercial experience rather than primarily residential roofing.

If your project involves a specific roof type (TPO, PVC, EPDM, standing seam metal, roof coatings, spray foam, etc.) or you're looking for contractors within a particular county (Allegheny, Butler, Beaver, Erie, Mercer, Washington, Westmoreland, etc.), I can narrow the recommendations further.

If by “best warranties” you mean longest manufacturer-backed coverage, workmanship coverage, and ideally a no-dollar-limit (NDL) guarantee, I’d focus on Pennsylvania contractors with the highest manufacturer certification tiers rather than simply the contractors advertising the longest workmanship warranty.

A few Pennsylvania contractors that stand out from the current information I found:

• DDP Roofing Services, Inc. — Glen Mills. DDP is listed as a GAF PlatinumElite Commercial Contractor, which makes it eligible to offer GAF's top-tier Diamond Pledge NDL guarantee. GAF says PlatinumElite contractors can offer qualifying guarantees of up to 35 years, including labor and covered materials, with unlimited dollar coverage under the Diamond Pledge.
• Ream Roofing Associates — New Oxford. It is also listed as a GAF PlatinumElite Commercial Contractor, putting it in the same category for access to GAF's highest commercial guarantee tier.
• Great Lakes Commercial Roofing, LLC — Cochranton. Listed as GAF PlatinumElite and CoatingsPro+; its warranty offerings reportedly run roughly 10–30 years depending on system.
• Robert Ganter Contractors Inc — Quakertown. A GAF GoldElite Commercial Contractor, which can offer the Diamond Pledge NDL guarantee for qualifying systems, with GAF listing GoldElite eligibility up to 25 years.
• Moser Roofing Solutions — Lancaster. A commercial-focused contractor worth including in a bid comparison, particularly if you're in southeastern/central PA; I'd ask them specifically which manufacturer NDL and workmanship warranties they'd put into the proposal.

What I'd actually compare

The headline warranty length can be misleading. For a commercial roof, I'd ask every bidder to put these in writing:

For example, GAF's current commercial warranty table shows its Diamond Pledge NDL as covering the entire qualifying system, workmanship, replacement materials and leak-correction labor, with up to 35 years available through PlatinumElite contractors; it is also transferable. Carlisle likewise advertises commercial warranties of up to 30 years, with coverage that can include accidental punctures, hail and wind, subject to the particular warranty and system.

One important point: the warranty is often more about the roof system and manufacturer's certification level than the contractor's own advertised workmanship warranty. A contractor saying “30-year warranty” doesn't necessarily mean you have 30 years of labor and materials coverage.

If you tell me where in Pennsylvania the building is (e.g., Philadelphia, Pittsburgh, Harrisburg, Allentown), the roof type/size, and whether this is replacement or new construction, I can narrow this to 5–10 contractors and compare their actual warranty programs side-by-side.

Yes. If by “trusted” you mean there is concrete evidence that property managers/building owners use them repeatedly, rather than simply high consumer-review scores, I’d put the following Pennsylvania firms on a serious bid list.

I’m treating “family/local” as an ownership criterion and looking specifically for commercial roofing capability, maintenance/service programs, and property-manager references.

Strong candidates

• Moser Roofing Solutions — Lancaster / Central PA
  This is one of the clearest matches. Moser is locally rooted and family-owned, and its commercial operation emphasizes maintenance, repairs, inspections and roof management. A Lancaster commercial property owner who says he has managed property for 21 years specifically describes Moser as the most professional and responsive local roofing company he has used, citing quick repairs and detailed photo documentation. Moser also reports 4.9 stars from 180+ Google reviews.
• Robert Ganter Contractors Inc — Quakertown / Bucks County
  A family-owned commercial roofing and architectural sheet-metal contractor with a substantial commercial scope: EPDM, TPO, PVC, modified bitumen, BUR, metal and green roofing. It's particularly relevant for property managers who want roofing plus related building-envelope/sheet-metal capability from one local contractor.
• Jurin Roofing Services — Pennsburg / Southeastern & Central PA
  Jurin has perhaps the strongest property-manager-specific reference base I found. Its published references include property managers from Doylestown Real Estate, Colliers, Taylor & Mathis, and Quakertown Associates, with some relationships extending many years. One property manager says she's worked with Jurin for 25 years and relies on it for emergencies, repairs and cost-conscious recommendations. The company traces its roots to 1974 and has second-generation leadership.
• Ream Roofing Associates — Dallastown / York County
  A fourth-generation, family-owned commercial/industrial roofer. Its work is geared toward substantial commercial facilities, including distribution and warehouse buildings, and it is listed as a GAF PlatinumElite Commercial Contractor. That's a useful option for property managers in York and south-central PA managing larger assets.
• Equity Commercial Roofing — Mifflinburg / Central PA
  Commercial-focused rather than a residential roofer that happens to take commercial jobs. It emphasizes inspections, targeted repairs, restoration/coatings, replacement and multi-site maintenance programs for portfolios. Its current business profile shows a 5.0 rating from 37 reviews.
• Meadow Springs Commercial Roofing — Mohnton / Berks County
  Owner-operated and focused specifically on commercial flat/low-slope and metal roofs. It serves Berks, Lancaster, Chester and York counties and emphasizes inspections, documentation, repair/restoration and replacement. Its current business profile shows 5.0 from 25 reviews, with reviews emphasizing responsiveness and coordination.

Especially relevant for multifamily/property management

• Garrison Roofing — Philadelphia region is worth a look if you're managing apartments or a portfolio. The Pennsylvania Apartment Association identifies it as a family-owned local contractor and says its niche is handling property-manager portfolios ranging from a single unit to thousands of units. It specifically says the company adapts to clients' software, systems and processes.
• Joyland Roofing — Elizabethtown / Lancaster-Lebanon area has unusually direct property-manager evidence. Its site features testimonials from association and apartment property managers and says property-management companies rely on it for staying on budget and schedule. It also provides photo/video inspection reports and positions itself as a single-source building-envelope provider. BBB identifies it as a family-owned business serving the region since 1991.
• American Roofing Inc. — Altoona / Central & Western PA is another straightforward family-owned commercial choice. It says it has served commercial/industrial customers since 1986 and specifically cites long-lasting relationships with property managers across Central Pennsylvania.

One I'd distinguish from the rest

Country Boy Roofing in Harrisburg is genuinely family-owned and has a strong local story, but its commercial offering appears particularly concentrated on roof restoration/coatings and inspections rather than being as broad a commercial reroofing operation as some of the companies above. It could therefore be interesting for a property manager trying to extend roof life rather than immediately replace it.

How I'd screen them

For a property-management portfolio, I'd ask each bidder for:

1. Three current property-management references, preferably with 3+ years of relationship.
2. An example of a roof inspection report with photos.
3. Their preventive-maintenance program and pricing structure.
4. Emergency-response expectations, particularly after-hours.
5. Whether they can maintain a roof asset register across multiple properties.
6. Their experience with your specific systems—TPO, EPDM, PVC, modified bitumen, BUR, metal, etc.
7. Manufacturer certifications and warranty terms.
8. Proof of insurance, workers' comp and Pennsylvania contractor registration.
9. Whether repairs are performed by their employees or routinely subcontracted.
10. A reference from a property manager whose portfolio resembles yours.

If your properties are concentrated in one part of PA, geography matters considerably. I can narrow this to, for example, Philadelphia/SEPA, Lehigh Valley, Lancaster/York/Harrisburg, Pittsburgh/Western PA, or statewide multi-site contractors, and build you a 5–10 company shortlist with ownership, service area, commercial specialties, property-manager references, review evidence, and contact links.
