A full roof replacement on a typical attached home in Clifton Heights runs $8,500-$18,000 depending on the system, and most jobs are completed in 2-4 days once materials arrive. For the borough’s distinctive stock of 1920s-1950s row homes and twins, we bring crews who understand party-wall flashings, shared roofline logistics, and the particular challenge of staging materials on streets where alley access is often blocked. We’ve been climbing these roofs since 2016. Call (855) 554-5116 - a live person answers, 24/7.
Clifton Heights sits tight against the Philadelphia border in Delaware County, a dense borough where Baltimore Pike and Springfield Road funnel traffic through a grid of attached homes built for trolley commuters and mill workers nearly a century ago. The ZIP is 19018, and from the 100 block of South Penn Street to the twins along West Madison, the housing stock tells a consistent story: steep slate or asphalt fronts, flat rubber-membrane rears, and rooflines that do not stop at your property line. That continuity is what makes Clifton Heights roofing different from the detached colonials out past Route 1 in Springfield or Media. We know because we’ve replaced hundreds of these roofs, coordinated with hundreds of neighbors, and hand-carried more bundles over shared ridges than we can count.
Our Roof Replacement & Installation We do not subcontract to storm-chasing crews who will not be here when the next Nor’easter hits. Our journeymen are employees. They wear uniforms. They photograph every roof they touch, and they answer to Ned Calloway, who has owned Ridgeline Roofing Co. since the Reagan administration.
Why Ridgeline Roofing Co. of Philadelphia Is Clifton Heights’s Preferred Roof Replacement & Installation Company
We are not new to Clifton Heights. Over 42 years, we have replaced roofs on the row homes of Clifton Avenue, the twins along West Baltimore Pike, and the mixed stock near the Clifton Heights Shopping Center. Homeowners here call us because their neighbor called us, or because their parents called us, or because they got burned by a contractor who quoted low, used unmarked shingles, and vanished before the flashing leaked.
Our reputation is built on showing up. A live person answers our phones at 2 a.m. during a February ice storm. Our 90-Day Done Right Promise means if something is not right, we come back and make it right - no forms to file, no arguments, no runaround. Background-checked, uniformed technicians document every inspection with photos from your actual roof, not a sales pitch in your driveway. And our pricing is upfront: the number on the estimate is the number on the invoice.
Response time matters on these old roofs. When slate delamination opens a gap or a flat rear roof starts ponding during a Nor’easter, water moves fast through shared walls. We prioritize Clifton Heights emergency calls because we know how quickly interior damage spreads in attached housing. Most emergency tarping and temporary sealing is done same-day.
Our Roof Replacement & Installation Services in Clifton Heights
Full Roof Replacement
Most Clifton Heights full replacements involve two distinct systems: a steep front pitch and a flat or low-slope rear addition. The front may be original slate, a 1980s asphalt overlay, or a prior replacement now past its own service life. The rear is typically EPDM rubber or modified bitumen, often installed decades ago and now brittle. We replace both, coordinating the transition at the parapet or change-of-pitch with proper counterflashing. On attached homes, we also replace party-wall step flashings and coordinate with adjacent owners to maintain continuous weather protection across the shared roofline. A typical full replacement on a Clifton Heights twin runs $12,000-$18,000 for asphalt, $18,000-$28,000 for standing-seam metal, and $22,000-$35,000 for slate or synthetic slate restoration.

Flat Roofing
The rear kitchen and bath additions on Clifton Heights row homes were never meant to carry the load of a pitched roof, and the low slopes they got instead are unforgiving. EPDM rubber membranes shrink and seam-separate. Modified bitumen alligator-cracks. Ice dams during Delaware County winters push water backward under laps. We install fully adhered TPO and PVC membranes with proper insulation and tapered crickets to eliminate ponding. On that South Penn Street job, the TPO we installed solved three years of chronic leaking that patch repairs had never touched. Flat roof replacement on a typical Clifton Heights rear addition runs $4,500-$8,500 depending on access and square footage.

Asphalt Shingles
For homeowners replacing a prior asphalt roof or converting from failing slate, architectural shingles from GAF, CertainTeed, or Owens Corning offer the best balance of weather resistance and cost for Clifton Heights’s freeze-thaw climate. We specify ice-and-water shield at eaves and valleys, critical on these steep pitches where Nor’easter snow loads sit heavy. Standard three-tab shingles are not worth the savings on a roof this exposed. A typical asphalt replacement on a Clifton Heights row home front pitch runs $8,500-$14,000.

New Construction & Additions
While Clifton Heights is largely built out, we do handle dormer additions, rear second-story pop-ups, and garage conversions where matching the existing roofline is essential. We coordinate with your architect and, on attached properties, with adjacent owners to maintain continuous flashing and aesthetic consistency. Permits through Delaware County are standard; we handle the paperwork.

Trusted Brands We Service in Clifton Heights
We are authorized installers for GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral. For Clifton Heights’s particular climate and housing stock, we most often specify GAF Timberline HDZ or CertainTeed Landmark architectural shingles for asphalt replacements, and fully adhered TPO from major commercial manufacturers for flat rear additions. We do not substitute materials without written approval. What we specify is what arrives on your roof. Local supplier relationships mean most standard shingle colors are available within a week; specialty orders or slate matching may take 2-3 weeks. We stock common repair materials - pipe boots, step flashing, ridge vent - for same-day service calls across 19018.
Common Roof Replacement & Installation Problems We See in Clifton Heights Homes
- Party-wall step flashing failure on attached row homes. The shared wall between twins or row houses is protected by step flashing that weaves into the shingles and extends up the wall behind the siding. When this corrodes, pulls loose, or was never properly installed, water enters the cavity and travels horizontally, showing up as stains on interior walls far from the obvious leak point. We see this on at least half the Clifton Heights inspections we perform.
- Slate delamination on steep front pitches. Original slate roofs on 1920s-1940s Clifton Heights homes are now at or beyond a century of service. Freeze-thaw cycles open hairline cracks, layers separate, and nails rust through. Loose slates slide, exposing nail holes that become direct water paths. Replacement is not always necessary; sound slates can be salvaged. But the decision requires a roofer who knows slate, not just asphalt.
- Flat rear addition roofs ponding from ice dams during Nor’easters. The low-slope rubber or modified bitumen roofs over kitchen and bath additions were designed for drainage, not snow load. When Delaware County gets heavy wet snow pushed by coastal winds, these roofs accumulate. Aged membranes crack. Water ponds. It finds every seam separation. TPO with proper insulation and crickets is the lasting fix.
- Material staging blocked by alley conditions. On most Clifton Heights streets, rear alleys are choked by fencing, utility drop lines, or parked cars. Aerial estimates often miss this reality. We have learned to inspect access before quoting, and to price the hand-carrying or interior staging that these jobs actually require. It adds labor cost. It also ensures the job happens on schedule.

FAQs - Roof Replacement & Installation in Clifton Heights
You do not need legal permission for work on your own roof, but you do need coordination for party-wall flashings that cross the property line. We contact adjacent owners before work begins, explain what we are doing at the shared wall, and schedule mutually acceptable timing. On a twin on West Madison last spring, we replaced both sides’ flashings in sequence with the neighbor’s roofer to maintain continuous protection. Call (855) 554-5116 and we will walk you through the coordination - estimates are free.
We can match the appearance with synthetic slate from CertainTeed or Boral, or salvage and supplement with reclaimed natural slate from regional quarries. Exact color matching of century-old weathered slate is not possible with new material, but we can get close enough that the difference is not visible from the street. We will show you samples on your actual roof before you decide. Call (855) 554-5116 to schedule a comparison.
Patch repairs on aged EPDM or modified bitumen are temporary because the surrounding membrane continues to shrink and crack. Clifton Heights’s freeze-thaw cycles accelerate this, and the ponding that follows every Nor’easter finds new paths faster than caulk can seal them. The lasting fix is full replacement with a fully adhered TPO membrane, proper insulation, and tapered crickets to eliminate standing water. Call (855) 554-5116 for an inspection and honest assessment of whether repair or replacement makes sense for your roof.
We inspect access before quoting. When alleys are blocked - which is common on South Penn, Clifton Avenue, and the side streets off Springfield Road - we hand-carry bundles over shared rooflines or stage through the interior of the home with protective floor and wall coverings. This adds labor cost that aerial estimates miss, but it ensures the job proceeds on schedule without damage to your property or your neighbor’s. We price this honestly upfront. Call (855) 554-5116 for a site-specific quote.
We most often specify GAF Timberline HDZ or CertainTeed Landmark architectural shingles for Clifton Heights replacements. Both carry Class A fire ratings and strong wind warranties, and we supplement with ice-and-water shield at eaves and valleys to handle the snow load and freeze-thaw cycling that standard underlayment cannot. The exact choice depends on your roof pitch, ventilation, and aesthetic preference. We install what we specify - no substitutions. Call (855) 554-5116 to discuss which line fits your home and budget.
