We’ve been working in Glenolden since the mid-1980s, and we know this borough’s roofs like we know our own tools. The 19036 zip is built tight - brick row homes and twins from the 1940s and 1950s, narrow alley setbacks, shared party walls, and parking that requires a plan before the truck even leaves the shop. Our Roof Replacement & Installation crews are trained for exactly these constraints. We bring compact equipment, we coordinate alley access, and we don’t treat your home like a suburban ranch with room to spare.
What sets Glenolden apart, roof-wise, is the double system on nearly every house: a sloped asphalt-shingle main roof and a flat or low-slope rear addition. Two different roofing systems, one home, and a junction between them that fails more predictably than any other spot in the borough. A crew that only knows shingles or only knows flat roofs is going to miss something. We handle both, on the same call, with the same crew.

Our Roof Replacement & Installation Services in Glenolden
Full Roof Replacement
When a Glenolden roof has reached the end, we strip to the deck, inspect for rot or inadequate ventilation, and build back properly. On row homes and twins, this means managing shared rooflines with neighbors, protecting party-wall flashing, and staging materials in tight spaces without blocking alley traffic. We’ve replaced full roofs on homes from the 300 block of North Street to the twins along Summit Avenue - each with its own access puzzle, each solved before the first shingle comes off the truck.
Flat Roofing for Rear Additions
This is where Glenolden’s housing stock demands real expertise. Those rear additions - kitchens, bathrooms, utility rooms tacked onto the original 1940s footprint - were roofed with coal-tar or built-up roofing that is now well past its service life. We install fully adhered TPO and modified bitumen systems designed for low-slope applications, with proper drainage and scupper protection. On a twin on Summit Avenue near Chestnut, we found the original coal-tar flat roof on the rear addition had ponding water that wicked up under the step flashing, soaking the shared party wall. We installed a fully adhered TPO flat roof on the addition and new CertainTeed Landmark shingles on the main slope, with a continuous counter-flashing system that isolates the two planes. Problem solved. Done right - and if it’s not, we make it right.
Asphalt Shingle Installation
Most Glenolden main roofs are asphalt shingles, and we install GAF, CertainTeed, and Owens Corning lines with proper underlayment, ice-and-water shield at the eaves, and ventilation that accounts for the borough’s compact attic spaces. Southeastern Pennsylvania’s freeze-thaw cycle - temperatures swinging above and below freezing from November through March - creates persistent ice-dam risk along the low-pitched eaves of Glenolden’s row homes, particularly where inadequate attic insulation allows heat to escape and refreeze at gutters. We build to handle that.
Metal Roofing
For Glenolden homeowners who want longevity and don’t mind the higher upfront cost, metal roofing delivers 50+ years of service. We install standing-seam and metal shingle systems, with particular attention to the thermal expansion details that matter in climates with freeze-thaw stress. Metal makes sense on detached homes in the borough or where historical appropriateness aligns with the neighborhood character.

We are authorized installers for GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral - seven manufacturer lines, no substitutions. For Glenolden customers, this means we stock the shingles, underlayment, and flat-roof membranes your job actually calls for, not whatever’s on clearance.

Common Roof Replacement & Installation Problems We See in Glenolden Homes
- Junction flashing failure: The seam where sloped main roofs meet flat rear additions is the dominant chronic leak source in Glenolden. Separating these two planes with proper counter-flashing requires a crew fluent in both shingle and flat-roof work - a combination many contractors simply don’t bring.
- Ponding water on clogged drain scuppers: Narrow alley setbacks on row homes let leaves and debris accumulate, blocking scuppers and causing membrane failure. The water sits, the roof rots from the top down, and interior ceiling damage spreads before homeowners notice the stain.
- Shared-roofline flashing separation: Step flashing at party walls on mid-century twins lifts during freeze-thaw cycles, opening gaps that allow water into shared attic spaces. Repairing this requires coordination with neighbors and precision work in tight quarters.
- Aging original flat-roof membranes: The coal-tar and built-up roofing installed on Glenolden’s rear additions in the 1950s and 1960s has exceeded its design life by decades. These systems don’t fail dramatically - they seep, they crack, they let moisture migrate slowly into framing and insulation.

FAQs - Roof Replacement & Installation in Glenolden
Yes - it’s the most common leak source in Glenolden’s 19036 zip. The junction flashing between sloped shingles and flat membrane fails because the two systems expand, contract, and drain differently, and original installations rarely included proper counter-flashing. We repair this junction routinely, usually by installing a continuous metal counter-flashing that isolates the planes and allows each to move independently. Call (855) 554-5116 - we’ll inspect it and show you photos of exactly what’s failing.
Absolutely. We do this regularly on Glenolden twins and row homes. The flat rear addition is a separate roofing system with its own deck, membrane, and drainage, and we can replace it independently while protecting the existing shingle roof and its flashing. We’ll coordinate the junction detail to ensure the two systems drain properly without cross-leaking. Most flat-roof replacements on Glenolden rear additions are completed in a single day.
Most likely, yes - and specifically from ponding water that isn’t draining through clogged scuppers or a failed membrane. On Glenolden’s narrow alley setbacks, debris accumulates fast, and the original coal-tar or built-up roofing on these additions has exceeded its service life by decades. The water sits, migrates through cracks, and shows up as stains on your ceiling. We inspect the drainage path, clear or replace scuppers, and install a new membrane if needed. Call (855) 554-5116 for a free inspection - we’ll trace the leak to its source.
Shared party-wall flashing is a joint responsibility, but in practice, the first homeowner to spot the leak usually needs to coordinate the repair. We’ve worked with Glenolden neighbors on both sides of party walls many times - we document the condition, explain what’s needed, and can often complete the repair with minimal disruption to both households. The 90-Day Done Right Promise applies regardless of how many names are on the invoice. If the flashing serves both roofs, both homeowners benefit from doing it right.
We do, and we recommend them for Glenolden’s row homes and twins with low-pitched eaves. Southeastern Pennsylvania’s freeze-thaw cycle creates ice-dam conditions regularly from November through March, and snow guards combined with proper ice-and-water shield and attic ventilation significantly reduce the risk. We assess each roof’s pitch, exposure, and insulation before recommending a specific guard system. Most installations are done as part of a full replacement or during targeted eave repairs.
