Fast, Reliable Roof Replacement & Installation Across Drexel Hill
A full roof replacement on a Drexel Hill twin home typically runs $12,000-$28,000 depending on whether you’re replacing slate with asphalt shingles, preserving original slate, or addressing the flat rear addition that’s so common here. Most of our Drexel Hill jobs start within 5-7 business days of your call, and we complete the majority in 3-5 days once materials arrive. Call (855) 554-5116 and a live person will answer - any hour, any day.
We’ve been climbing Drexel Hill roofs since 2016. We know the difference between a Welsh slate that’s worth saving and one that’s delaminated past the point of repair. We know which contractors on State Road or Garrettford Avenue will let you down by quoting only the flat roof while the main slate crumbles above. And we know that replacing a roof on a semi-detached twin means respecting the shared ridge line - your neighbor’s home depends on our flashing every bit as much as yours does.
Our Roof Replacement & Installation team serves all of 19026, from the tree-lined streets near Drexel Hill Middle School to the tighter blocks off Burmont Road. We’re not storm chasers with out-of-state plates. We’re the crew that plans to be here in thirty years, checking the same ridge lines we installed today.
Why Ridgeline Roofing Co. of Philadelphia Is Drexel Hill’s Preferred Roof Replacement & Installation Company
Homeowners in Drexel Hill call us because we’ve earned a strong local reputation across Delaware County over four decades - not through billboards, but through neighbors telling neighbors that we showed up, did what we said, and came back when something needed adjusting.

We typically reach Drexel Hill properties within 45 minutes of our Philadelphia base, and we carry stock for common repairs so we’re not ordering parts while your living room takes on water. Every technician is background-checked and uniformed - the same standard we’d hold for work done in our own mother’s home. And when you call (855) 554-5116, a live person answers. Nights, weekends, the middle of a March ice storm. No voicemail trees.
We understand Drexel Hill’s housing stock in a way out-of-town crews simply don’t. The brick twins built between 1920 and 1945, many still carrying original slate, require a different approach than the ranch homes five miles west. The semi-detached configuration means every roofing job must address the shared ridge line and party-wall flashing between two separately owned halves. We’ve coordinated these repairs dozens of times. We know which permits Delco requires, how to document the work for historic considerations, and how to keep both halves of a twin watertight while we work.
Our Roof Replacement & Installation Services in Drexel Hill
Full Roof Replacement
Most Drexel Hill twins need full replacement not because of one catastrophic failure, but because the original slate has reached 80-100 years of age and the flat rear addition has leaked once too often. We replaced a failing rear-addition flat roof on a twin on School Lane, only to find the main slate roof above was delaminating from decades of freeze-thaw. We worked with both owners to coordinate a full slate-to-asphalt transition using GAF Timberline HDZ shingles, ensuring proper flashing at the shared party wall. That’s the kind of thoroughness we bring to every Drexel Hill job - we don’t patch and pray.
A full replacement on a typical Drexel Hill twin runs $15,000-$28,000 for slate-to-shingle conversion, or $22,000-$38,000 for slate restoration with new underlayment. We handle the dumpster, the permits, the neighbor coordination, and the cleanup. The price we quote is the price you pay.

New Construction Roofing
New builds in Drexel Hill are rare, but we do see additions, dormer expansions, and the occasional teardown-rebuild near the business district. We install to code for Delaware County’s wind and snow loads, and we match existing rooflines so the new work doesn’t look like an afterthought. Our crew has worked on new construction alongside local builders who’ve served Drexel Hill for generations.

Asphalt Shingle Installation
For most Drexel Hill homeowners replacing century-old slate, asphalt shingles offer the best balance of durability, cost, and aesthetic compatibility with the neighborhood’s historic character. We install GAF Timberline HDZ and CertainTeed Landmark shingles - both carry strong wind ratings and color palettes that complement brick facades. A typical asphalt shingle replacement on a Drexel Hill twin runs $12,000-$22,000, including removal of the old slate and proper installation of ice-and-water shield at the eaves where ice dams form.
We never substitute materials. The brand we specify is the brand you get.

Flat Roofing
Those low-slope rear additions on Drexel Hill twins? They’re often the first thing to fail. We install TPO, modified bitumen, and built-up roofing systems designed for the minimal pitch and the standing water that follows our heavy Delaware County rains. A flat roof replacement alone typically runs $4,500-$9,000, but we always inspect the main roof above - because contractors who quote only the flat section often find themselves called back when the crumbling slate starts leaking six months later.

Trusted Brands We Service in Drexel Hill
We install GAF, CertainTeed, and Owens Corning products - three manufacturers whose shingle lines we’ve worked with long enough to know which colors fade fastest in southeastern Pennsylvania’s sun and which hold up best to our freeze-thaw winters. We don’t stock mystery brands or job-lot materials. What we specify in your estimate is what arrives on your roof, with serial numbers and warranty cards to match. For Drexel Hill customers, this means no waiting on special orders from two states away. We keep common colors and accessories in our Philadelphia warehouse, so most Drexel Hill replacements start within a week of your signed approval.
Common Roof Replacement & Installation Problems We See in Drexel Hill Homes
- Ice dams on low-slope shed dormers. The shallow-pitched dormers common on Drexel Hill twins trap snowmelt that refreezes at the eaves, forcing water backward under slate and into the interior - often before any visible leak appears in the ceiling below.
- Moss and lichen trapping moisture against masonry. North-facing slate roofs in Drexel Hill’s tree-canopied blocks grow thick with moss that holds humidity against aging mortar parapets, accelerating both mortar decay and the slate delamination that follows.
- Contractors missing the full scope. A crew quotes $6,000 for the leaking flat rear addition and never inspects the 90-year-old slate main roof above. Six months later, the homeowner calls us for the real job - having paid twice for mobilization and scaffolding.
- Failed party-wall flashing between twins. The shared ridge line on semi-detached homes requires precise flashing that respects both property lines. Amateur work here leaks into both halves, and neighbor disputes follow.

FAQs - Roof Replacement & Installation in Drexel Hill
If your slate is more than 80 years old and showing delamination, replacement is usually the wiser investment - spot repairs on failing slate become a game of whack-a-mole that costs more over five years than a full conversion. We assess what percentage of your slate is salvageable; if it’s under 60%, we recommend slate-to-asphalt transition with proper ice-and-water shield. Call (855) 554-5116 and we’ll give you an honest assessment - no charge for the inspection.
You don’t need formal approval for work on your own property, but you do need coordination for the shared ridge line and party-wall flashing - and practically speaking, a good neighbor conversation prevents disputes and ensures both halves are protected. We handle this coordination regularly on Drexel Hill twins. Our crew has sat down with both owners, explained the flashing plan, and scheduled work that respects both households.
Not always, but we inspect the main roof before quoting any flat work - because in Drexel Hill, the flat roof often fails first while the century-old slate above is already compromised. We’ve seen too many homeowners pay for flat replacement twice because the first contractor missed delaminating slate six feet overhead. Our estimate will give you the full picture, not just the easy sale.
GAF Timberline HDZ and CertainTeed Landmark both offer dimensional profiles and color blends that complement Drexel Hill’s brick twins without trying to fake the look of slate. We avoid cheap three-tab shingles on these homes - they look thin against substantial masonry and don’t carry the wind rating our Delaware County weather demands. Most of our Drexel Hill customers choose charcoal, weathered wood, or slate gray blends.
Southeastern Pennsylvania’s repeated winter freeze-thaw cycles - daytime highs in the 40s, overnight lows in the teens - force moisture into slate fissures that expand and contract until the stone delaminates. On Drexel Hill’s low-slope dormers, melted snow refreezes at the eaves and creates ice dams that lift flashing and back water under courses. This pattern is more severe here than in milder climates because our winters are just cold enough, just long enough, to do cumulative damage across decades. Proper ice-and-water shield and adequate attic ventilation are the best defenses - we install both as standard, not upgrades.
