We’ve been working on Wharton’s roofs since 2016. Ned Calloway started this company with the belief that a roof should be fixed right and left right, and that hasn’t changed in over 42 years. Wharton’s narrow brick rowhomes, built mostly between 1890 and 1940, present roofing challenges you won’t find in Cherry Hill or the Main Line. The flat roofs, shared parapets, and interior drains of ZIP 19148 demand a different skill set than pitched shingle work. We’ve trained our crews specifically for this.
Why Ridgeline Roofing Co. of Philadelphia Is Wharton’s Preferred Specialty Roofing Company
Our reputation in Wharton was built one rowhome at a time. We’ve replaced tar-and-gravel roofs on Wharton Street, stopped lateral leaks spreading through shared parapets on Federal Street, and cleared scuppers backing up across three attached properties near 11th and Wharton. Homeowners here call us back, and they send their neighbors.
Response time matters on a flat roof. When a drain clogs during a February ice storm, water doesn’t trickle down shingles - it pools, then travels under the parapet into your bedroom ceiling. That’s why we keep crews staged for South Philadelphia. Most Wharton calls reach us in under an hour, and our 24/7 live answering means you’re never waiting on a callback window while your plaster bubbles.
We know the local housing stock because we’ve walked hundreds of these roofs. The 2-story narrow brick rows with party walls, the parapet-edged decks, the original built-up roofs now 40 or 60 years past their prime. We document every inspection with photos from your actual roof, not a speech in the driveway. And our 90-Day Done Right Promise means if something isn’t right, we come back and make it right - no paperwork, no arguing.
Our Specialty Roofing Services in Wharton
Modified Bitumen Roofing
Modified bitumen is what we install most often in Wharton, and for good reason. These torch-applied or self-adhering membranes handle Philadelphia’s 20-30 annual freeze-thaw cycles better than the old tar-and-gravel they replace. On a typical Wharton rowhome, we strip the failed built-up roof to the deck, install a base sheet, then cap it with a granulated modified bitumen surface that flexes instead of cracking. The reinforced flashing at shared parapets - where water loves to sneak between attached homes - is where our experience shows. A proper modified bitumen job on a Wharton rowhome runs $6,800-$9,400 for complete replacement.

Built-Up Roofing (BUR)
Some Wharton homeowners want to stay with what’s worked for a century, and we still install built-up roofing where it makes sense. Multiple layers of bitumen and reinforcing fabric, finished with gravel or a reflective coating. BUR performs well on large flat decks with minimal penetrations, though on Wharton’s smaller rowhome roofs with shared parapets and multiple drains, we often steer clients toward modified bitumen for better seam integrity. When we do install BUR, we use proper flood coats and gravel embedment - no shortcuts. Expect $5,500-$8,200 for a Wharton rowhome BUR replacement.

EPDM Roofing
EPDM - the black rubber membrane - has its place in Wharton, particularly on rowhomes with straightforward rectangular decks and good drainage. The single-ply system installs fast, which keeps labor costs down. We ballast or fully adhere it depending on wind exposure and parapet height. EPDM’s weakness in this neighborhood is the same as its strength: the seams. On a roof where one clogged scupper can send water laterally under three attached properties, seam quality is everything. Our EPDM work on Wharton rowhomes typically runs $5,200-$7,800.

Solar Ready Roofing
Wharton homeowners adding solar panels need a roof that outlasts the array. We install solar-ready modified bitumen and TPO systems with reinforced attachment zones, so your racking doesn’t compromise the membrane. South Philly’s summer heat buildup on dark flat surfaces is severe - a solar-ready white TPO reflective roof can drop surface temperatures 40 degrees versus black EPDM, extending membrane life and reducing cooling load. Solar-ready installations in Wharton range from $7,500-$11,000 depending on deck condition and attachment complexity.

TPO Roofing
White thermoplastic polyolefin is gaining ground in Wharton for its reflectivity and heat-welded seams. On a dense urban block where summer roof surfaces hit 160°F, that reflectivity matters. TPO’s seams are fused, not taped or glued, creating a monolithic surface that resists the lateral water migration common in shared-parapet leaks. We install TPO from GAF and CertainTeed with proper fastening patterns for Philadelphia’s wind loads. Wharton TPO jobs generally run $6,200-$9,800.

Green Roof Systems
Green roofs are possible on Wharton’s flat rowhomes, though they’re less common than in Center City’s commercial buildings. The structural load of soil and vegetation requires engineering assessment - these old brick rows weren’t built for it. Where structurally feasible, we install intensive or extensive green roof assemblies with proper drainage mats, root barriers, and irrigation. The payoff is stormwater management and urban heat reduction, but the investment is significant: $18,000-$35,000 for a typical Wharton rowhome green roof installation.

Trusted Brands We Service in Wharton
We don’t substitute materials. When we quote GAF, CertainTeed, or Owens Corning, that’s what arrives on the truck. We’re authorized installers for all seven manufacturer lines - GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral - which means our Wharton customers get full warranty protection, not a contractor-grade product with the label scraped off. We stock modified bitumen rolls, EPDM membrane, and TPO sheets at our Philadelphia warehouse, so most Wharton repairs don’t wait on a delivery. The brand on your roof should be the brand you paid for. A square deal is the price we quote and the materials we promise.
Common Specialty Roofing Problems We See in Wharton Homes
- Freeze-thaw cycle damage. Philadelphia’s 20-30 annual freeze-thaw cycles crack brittle old built-up roofing membranes, especially at seams and penetrations. Water seeps in, freezes, expands, and opens the breach wider. On Wharton’s flat roofs, that water ponds instead of shedding, and the cycle repeats until you’ve got a saturated deck.
- Clogged drains and scuppers. A single blocked scupper on a Federal Street rowhouse can back water across multiple rooflines. Because these homes share parapet walls, water travels laterally under the coping rather than staying put. The leak shows in your bedroom, but the clog might be two doors down.
- Failed parapet coping and flashing. The joint between adjacent Wharton rowhomes is a natural failure point. Deteriorated coping stones, rusted through-wall flashing, or failed counterflashing let water into the wall cavity. It’s often misdiagnosed as a roof leak when it’s really a parapet problem.
- Original tar-and-gravel roofs past service life. Many Wharton rowhomes still carry built-up roofs installed 40 or 60 years ago. The gravel embedment washes off, the asphalt oxidizes and cracks, and the underlying felt delaminates. At some point, patching becomes throwing good money after bad.

What moves the number? Deck condition is the big variable. A Wharton rowhome with rotted tongue-and-groove decking beneath the old roof needs structural repair before the new membrane goes down. Parapet height, access difficulty (some of these rows have no alley access), and whether we need to coordinate with attached neighbors for shared-wall flashing all affect the final figure. We provide upfront pricing - the number on the estimate is the number on the invoice. Call (855) 554-5116 for a free, no-obligation inspection and exact quote.

FAQs - Specialty Roofing in Wharton
We can repair it short-term, but a 100-year-old built-up roof with multiple patch layers is usually past the point where repairs make financial sense. We recently worked on a 1920s brick row house on Federal Street where the original tar-and-gravel roof had been patched so many times it resembled a quilt. We stripped it down to the deck, installed a new modified bitumen system with reinforced flashing at the shared parapet, and added a scupper guard to prevent the neighbor’s future clogs from backing up onto this roof. If your roof has more patch than original surface, replacement is the better investment. Call (855) 554-5116 and we’ll give you an honest assessment - free.
Responsibility depends on where the drain sits and what your deed or HOA specifies, but the practical reality in Wharton’s attached rows is that water doesn’t respect property lines. We often need access to multiple roofs to solve what looks like one homeowner’s leak. Our crew can document the drainage path with photos, identify the blockage, and coordinate with neighbors if shared repairs make sense. We’ve mediated these situations on Wharton Street and near 11th and Wharton - the key is stopping the water first, then sorting out who pays. Call us at (855) 554-5116 for emergency response.
We do, but only where structural engineering confirms the building can handle the load. Wharton’s 1890-1940 brick rowhomes weren’t designed for saturated soil and vegetation. An intensive green roof can add 80-120 pounds per square foot when wet. We work with structural engineers to assess joist capacity before quoting. Where feasible, the benefits are real: stormwater retention, heat island reduction, and longer membrane life. Expect $18,000-$35,000 for a typical installation. Call for a structural feasibility review.
Yes. Standing water on a flat roof accelerates membrane degradation, breeds mosquitoes, and adds structural load. In Wharton’s dense blocks, summer heat on dark ponding water can push roof surface temperatures past 170°F, cooking the asphalt or rubber beneath. More critically, ponding often indicates a drainage problem - clogged drain, improper slope, or sagging deck - that will worsen. We clear drains, correct slope with tapered insulation, or replace failed decking as needed. Most ponding issues resolve for $450-$4,500 depending on cause. Call (855) 554-5116 for diagnosis.
Yes. We install solar-ready modified bitumen and TPO systems with reinforced attachment zones pre-engineered for panel racking. On Wharton’s flat roofs, we specify white reflective TPO when possible - it drops surface temperatures 30-40 degrees versus black EPDM, which extends membrane life past the typical 25-year solar panel warranty. Solar-ready installation runs $7,500-$11,000. We coordinate with your solar installer on attachment patterns so their penetrations don’t void our workmanship guarantee. Call for a free solar-ready roof assessment.
Wharton’s flat-roof rowhomes demand a different kind of roofer than the suburban shingle crews. We’ve been climbing these roofs since 2016, learning how water moves through shared parapets, how freeze-thaw opens seams, how a clogged scupper three doors down becomes your bedroom stain. Our Specialty Roofing team brings that knowledge to every Wharton job, backed by the 90-Day Done Right Promise: if it’s not right, we make it right, no paperwork, no runaround. Live phones 24/7. Background-checked, uniformed technicians. Upfront pricing. Named for the ridge - the line where a roof proves itself.
