GAF Specialty Roofing in Philadelphia: What to Know First
We provide independent GAF specialty roofing service in Philadelphia, with most repairs completed in a single visit and estimates delivered before any work begins. Our pricing is upfront - the number we quote is the number you pay. If you own a GAF specialty system - whether it’s a TPO membrane on a South Philly row home addition, a Solar Ready roof in Fishtown, or modified bitumen on a West Philadelphia flat - we diagnose it, source the right parts, and fix it without runaround. Call (855) 554-5116; a live person answers, even at midnight on a Saturday when your ceiling stain just turned into a drip.
How GAF Products Fail - and How We Fix Them
- GAF EverGuard TPO: seam separation at membrane edges. Philadelphia’s freeze-thaw cycles harden the TPO over time, and the factory seams along parapet walls start to lift. We’ve found this especially common on roofs installed 2012-2018, before GAF adjusted the welding temperature specs. We cut back to sound membrane, weld in new GAF-reinforced TPO or a compatible aftermarket seam tape, and seal the termination bar properly so it flexes instead of fighting the wall.
- GAF Liberty Modified Bitumen: granule loss exposing the SBS membrane. On low-slope sections in neighborhoods like Queen Village and Bella Vista, tree debris holds moisture against the surface, accelerating granule wash-off. Once the black membrane shows through, UV degradation accelerates fast. We spot-apply GAF Liberty cap sheet patches where the substrate is sound, or recommend a full recover if the base sheet has taken water - no guesswork, photo evidence included.
- GAF Solar Ready roof system: inverter mounting points leaking. The pre-flashed curbs are solid, but aftermarket solar installers often drill additional penetrations that miss the reinforced zones. We see this on newer installs in Graduate Hospital and Passyunk Square. Our fix: remove the compromised area, install GAF-compatible pitch pans or custom-fabricated curb extensions, and re-seal with GAF’s approved sealant so the homeowner’s solar warranty and roof warranty both stay intact.
- GAF EverGuard EPDM: shrinkage pulling flashings loose. Black EPDM absorbs brutal summer heat on Philadelphia’s unshaded flat roofs, and after 15-20 years it shrinks toward the center. The metal edge flashings in Point Breeze and Gray’s Ferry start to gap. We mechanically re-secure the flashing, install a GAF-approved membrane expansion joint where needed, or transition to TPO if the EPDM has passed viable recovery - we never patch a roof that’s past honest repair.
- GAF built-up roofing (BUR): alligatoring and ponding water. Older BUR systems in Kensington and Port Richmond - some original to the 1980s housing stock - develop surface cracking that holds water. Ponding over 48 hours voids most remaining warranty coverage. We core-cut to check ply adhesion, then install a GAF modified bitumen recover board and new cap sheet, or specify a tapered insulation package if the structure allows. Ned Calloway spent enough rainy afternoons in Kensington watching buckets fill to know: a roof doesn’t lie - and neither do I.
Our GAF Specialty Roofing Process

You call, we answer. A live person picks up at (855) 554-5116, 24 hours a day. We schedule within 24-48 hours for non-emergencies, same day if water is coming in.
- 2
Photo-documented inspection. Our background-checked, uniformed technician walks your roof, shoots every detail, and shows you the problem on a tablet before we discuss solutions.

Parts decision: OEM or quality aftermarket. We stock common GAF TPO and modified bitumen materials. For older EPDM or discontinued BUR components, we source compatible aftermarket parts that meet GAF’s physical property specs - never a mismatch that risks your system’s integrity.

Upfront estimate, no surprises. The price we quote is the price you pay. We explain what’s necessary now, what can wait, and what we would do on our own mother’s home.
- 5
The repair, tested before we leave. We flood-test seams and flashings, verify drainage paths are clear, and clean every scrap of debris from your property.
- 6
Written 90-Day Done Right Promise. If it’s not right, we come back and make it right. No paperwork to file, no argument, no runaround.
