    Why Scarborough Homes Need Roof Repair More Than Most

    Scarborough's housing stock tells a story that shows up on every roof we inspect. The bulk of homes here were built between 1955 and 1975. Bendale's "Ben Jungle" subdivision went up in 1955 with Price-Bilt's split-level Catalina models. Woburn filled in through the 1960s. Malvern was one of the last major planned communities, built from 1970 to 1990. That means most Scarborough roofs are on their second or third set of shingles. The original roof structures are 50 to 70 years old. Plywood decking from that era may be softening. Attic ventilation rarely meets current building code. We've been repairing and replacing Scarborough roofs for over 40 years. We know what to expect when we pull back shingles on a 1960s side-split in Agincourt or a postwar bungalow in Birch Cliff.

      Common Roof Problems We See in Scarborough Neighbourhoods

      Every Scarborough neighbourhood has its own roofing personality based on when it was built and what sits underneath.

      Post-War Bungalows (Birch Cliff, Guildwood, Bendale)

      • Low-pitch hip roofs with minimal attic space
      • Ice damming is the number one issue. Warm air from the living space melts snow on the roof. Water refreezes at the eaves and backs up under shingles.
      • Original "strawberry box" flat-roof homes need membrane or torch-on replacement, not shingle overlay
      • Many have had additions with improper flashing where the new roof meets the old

      Split-Level Homes (Agincourt, Woburn, Highland Creek)

      • Multiple roof planes creating valleys and height transitions
      • Valleys are the most common leak point. Water channels into the intersection and wears through flashing faster than the surrounding shingles.
      • Back-splits with lower rear rooflines collect leaf debris from mature trees
      • Roof-to-wall transitions at the split are frequently under-flashed

      1970s-80s Two-Storey Homes (Malvern, L'Amoreaux)

      • Steeper pitches with 3-tab shingles now 40+ years old
      • Granule loss and curling on south-facing slopes
      • Bathroom exhaust fans often vented into the attic rather than through the roof. Creates moisture buildup, mould, and decking rot.

      Shingle repair or partial replacement

      If damage is limited to one area and the rest of your roof has 5+ years of life left, we repair just the damaged section. Common after wind storms or when a single valley fails.

      Full roof replacement with architectural shingles

      Most Scarborough homes on their second set of 3-tab shingles are candidates for a full replacement with modern architectural (laminate) shingles. These carry 30 to 50 year warranties and handle freeze-thaw cycling better than the 3-tab shingles originally installed.

      Flat roof membrane replacement

      Birch Cliff and Guildwood bungalows with flat or low-slope sections need torch-on modified bitumen or TPO membrane. We do not recommend shingle overlay on low-slope roofs.

      Commercial flat roofing

      Scarborough's commercial buildings along Eglinton, Lawrence, and the 401 corridor need flat roof systems designed for larger spans. We handle commercial roof repair from small retail plazas to industrial units.

          Frequently Asked Questions

          Yes. Split-levels have multiple roof planes meeting at valleys and height transitions. These intersection points are the most common source of leaks. We re-flash and reinforce every valley when doing repairs on split-level homes.

          Minor repairs (flashing, small shingle sections) typically run $300 to $800. A full roof replacement on a standard Scarborough home ranges from $8,000 to $15,000 depending on size, pitch, and materials. We provide free estimates with no obligation.

          Most Ontario home insurance policies cover sudden water damage from ice dams but not the roof repair itself. Prevention (proper ventilation and ice/water shield) is always more cost-effective than repeated claims.

          Most residential roof replacements are completed in 1 to 2 days. Complex split-level or multi-section roofs may take 3 days. We work in all seasons.

          In the City of Toronto, a building permit is not typically required for re-shingling or minor repairs. However, structural changes to the roof (adding dormers, changing the roof line) do require a permit. We handle all permit requirements when applicable.
