Sharon Hill sits just west of Philadelphia’s city line, a sub-square-mile borough where the 19079 zip code packs in row homes and twins built mostly between 1920 and 1940. We’ve replaced enough blistered porch roofs on Chester Pike and rebuilt enough shared chimney flashings near the Sharon Avenue corridor to know that roofing here is not like roofing in newer suburbs. The flat built-up sections over front porches, the layered membranes hiding under decades of patches, the water that migrates along party walls from three doors down - these are the problems that define our work in this borough. When you call us, you get a contractor who has already seen your exact roof type, probably on the same block.
Why Ridgeline Roofing Co. of Philadelphia Is Sharon Hill’s Preferred Specialty Roofing Company
We are not storm chasers. We are not a phone number on a magnet that disappears after the check clears. Ridgeline Roofing Co. was founded in 1984, and for over forty-two years we have hired local crews, trained apprentices into journeymen, and planned to still be answering calls in Sharon Hill thirty years from now. Our Specialty Roofing team includes technicians who have walked hundreds of flat porch roofs in Delaware County, and they arrive in uniform with background checks we would demand for work on our own mother’s home.
Our 90-Day Done Right Promise is written, not spoken into the wind. If it is not right, we come back and make it right - no paperwork avalanche, no argument, no runaround. The price we quote is the price you pay. A live person answers every call, including the middle of a February night when a nor’easter has peeled back your porch membrane and water is threading through the plaster - that’s when you need Sharon Hill Emergency & Storm Damage response, not a voicemail box.
We document every inspection with photos taken from your actual roof, not a scary speech in the driveway. And because we are authorized installers for GAF, CertainTeed, Owens Corning, and four other manufacturer lines, we do not substitute materials or hope you will not notice.
Our Specialty Roofing Services in Sharon Hill
Built-Up Roofing (BUR)
Built-up roofing is what most Sharon Hill porch roofs were born with: layers of felt, coal tar or asphalt, and surfacing gravel built up into a monolithic membrane. In the borough’s 1920s and 1930s twins, we regularly find three or four layers still in place, each one hiding the rot beneath. A typical BUR replacement on a Sharon Hill porch roof runs $2,400-$4,200, depending on how many layers we strip and whether the deck underneath has softened from years of ponding. We recently replaced a blistering built-up porch roof on a 1929 twin on Holly Avenue. The old membrane had three layers of felt and coal tar, ponding badly against the party wall. We stripped to deck, installed new tapered insulation and a fully adhered EPDM membrane, and re-flashed the shared chimney - stopping a leak that had been migrating down from the neighbor’s failed counter-flashing two units over.

Modified Bitumen
Modified bitumen arrived as the upgrade path for aging BUR systems: factory-manufactured sheets with rubber or plastic modifiers for flexibility and heat-welded or torch-applied seams. On Sharon Hill’s low-slope porch roofs, modified bitumen buys you better crack resistance through those twenty to thirty freeze-thaw cycles each winter, but only if the installation accounts for the ponding that happens where original construction did not build in adequate slope. We see a lot of modified-bitumen failures on Sharon Hill homes where a previous contractor laid new membrane over old without addressing the underlying drainage. Our approach: inspect the substrate, install tapered insulation where needed, then apply a two-ply system with proper seam welding. Most modified bitumen porch roof jobs in Sharon Hill fall between $2,800-$4,800.

EPDM Roofing
EPDM - the black rubber membrane - has become our go-to recommendation for Sharon Hill porch roofs that need long-term performance without the weight of built-up layers. A fully adhered EPDM system, installed over proper insulation with sealed seams and terminations, handles ponded water and thermal cycling better than the original BUR it replaces. For the Holly Avenue twin, EPDM was the right call: lightweight enough for the aging deck, flexible enough to accommodate minor settlement, and installed without open flames in a tight row-house setting. EPDM porch roof replacements in Sharon Hill typically range $3,200-$5,400. We also use EPDM for larger flat sections on commercial buildings along Chester Pike.

TPO Roofing
TPO’s white reflective surface makes sense for Sharon Hill properties where summer heat buildup accelerates membrane degradation. The white surface drops surface temperatures significantly compared to black EPDM or built-up roofing, which slows the blistering and alligator cracking we see so often on south-facing porch roofs. TPO installs at roughly the same price point as EPDM, $3,400-$5,600 for typical porch roof footprints in the borough. We recommend it for homeowners who plan to stay long enough to see the energy savings compound, and for any roof with solar readiness in mind.

Solar Ready Roofing
Solar readiness on a Sharon Hill flat porch roof means structural verification first: can the deck handle panel ballast or penetration-mounted racks? Then membrane selection that will outlast the panel warranty. We design solar-ready systems with TPO or EPDM substrates, proper flashing for rack penetrations, and load calculations that account for snow accumulation on the panels themselves. Most solar-ready retrofits on Sharon Hill porch roofs run $4,200-$7,800, including structural assessment and upgraded membrane. The investment only makes sense if the underlying roof has twenty years of life, which is why we will not sell you solar readiness over a deck that needs replacement.

Green Roof Systems
Green roofs - vegetated assemblies with growing medium and drainage layers - are rare in Sharon Hill’s dense row house fabric, but we have installed them on commercial properties and on one ambitious homeowner’s rear addition near the Darby border. Weight is the constraint: saturated green roof assemblies add significant load, and most 1920s porch decks were not engineered for it. Where structurally feasible, a Sharon Hill green roof runs $18-$28 per square foot installed, including irrigation and access for maintenance. We will tell you honestly if your structure can handle it.

Trusted Brands We Service in Sharon Hill
Ridgeline Roofing Co. is an authorized installer for seven manufacturer brands: GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral. For Sharon Hill homeowners, this means we stock membranes, flashing components, and specialty adhesives locally - not ordered from a warehouse three states away when your porch is leaking into the foyer. We specify GAF and CertainTeed modified bitumen and TPO systems for most residential flat roof applications in the borough, with Owens Corning components where insulation upgrades are part of the scope. Because we maintain relationships with local distributors, turnaround on specialty materials is typically twenty-four to forty-eight hours, not two weeks. No substitutions. No “this is just as good.”
Common Specialty Roofing Problems We See in Sharon Hill Homes
- Ponded water on flat porch roofs accelerates blistering and seam failure in built-up and modified-bitumen systems during humid summers. Sharon Hill’s porch roofs were often built with minimal slope, and decades of settling have made the problem worse. Standing water cooks the membrane from underneath, pushing vapors that separate felt layers and bubble the surface.
- Freeze-thaw cycles crack lap seams on low-slope porch roofs, especially where multiple felt layers have delaminated. The Philadelphia metro area averages twenty to thirty freeze-thaw events each winter, and each cycle is a wedge driven into every seam and termination. By March, the damage is done.
- Shared party-wall chimney flashing failures two units away can channel water along the wall cavity, causing interior leaks in a home whose own roofing is intact. This is the signature diagnostic challenge in Sharon Hill: the leak shows in your dining room ceiling, but the failure is three doors down. Our crews know to walk the block, not just the roof.
- Multiple layers of roofing hide deck rot and structural compromise. Sharon Hill’s older homes often carry two, three, or four generations of roofing material. Stripping reveals soft plywood, compromised rafter tails, and insect damage that no surface inspection can predict. We price for discovery, not for the best-case scenario.

FAQs - Specialty Roofing in Sharon Hill
The front porch flat roof is a separate system from the pitched roof above, and in Sharon Hill’s pre-WWII housing stock it is almost always built-up or modified bitumen over a low-slope deck that ponds water. Most contractors focus on the visible pitched roof and miss the porch membrane, which degrades faster from thermal cycling and standing water. We inspect both systems on every call. For expert Roof Repair in Sharon Hill, call (855) 554-5116 and we will check your porch roof - estimates are free.
Replace it if there are multiple layers, active deck rot, or chronic ponding that previous patches did not fix; repair it if the damage is isolated to one area and the substrate is sound. A third patch on a ninety-year-old BUR system is usually money thrown at a failing substrate. We will show you photos and give you both options with real numbers. Most full Roof Replacement & Installation - Sharon Hill projects on twins run $2,400-$4,200 and solve the problem for fifteen to twenty years.
Shared party walls mean shared chimney stacks, common wall cavities, and flashing that serves multiple units. A failed counter-flashing on your neighbor’s roof can channel water into your home even when your own roofing is intact. Our crews inspect adjacent units before diagnosing the source, and we coordinate repairs that involve multiple homeowners when necessary. This is standard practice for row-house work in Sharon Hill - any contractor who does not check the neighbor’s flashing is guessing.
Fully adhered EPDM or heat-welded TPO outperform original built-up roofing for longevity and leak resistance on low-slope porch decks. EPDM handles ponding and thermal movement well; TPO adds reflectivity that reduces summer heat loading. For most Sharon Hill porch roofs with solar potential, we recommend TPO. For shaded or north-facing applications, EPDM is the proven choice. We match the membrane to your specific roof after inspection.
Yes, if the deck structure passes load assessment and the membrane beneath is designed to outlast the panel warranty. We install solar-ready systems with reinforced TPO or EPDM substrates, proper penetration flashing for rack mounts, and ballast calculations that account for snow load. Most Sharon Hill porch decks from the 1920s and 1930s require structural reinforcement before solar is viable. We assess honestly and will not install panels over a deck that cannot carry them. Call (855) 554-5116 for a structural and solar-readiness evaluation - estimates are free.
