Roofing McCandless, PA — What We Actually See Here
The Town of McCandless is largely a 1950s–1970s suburb: brick and aluminum-sided ranches, colonials and split-entries on generous lots. Roofs here are typically simple in shape but old in structure — we routinely find 1x6 plank decking with gaps, original felt underlayment, and cut-in gable vents doing the work a ridge vent should be doing. On a plank-deck McCandless tear-off we re-sheet in OSB where needed and install a full synthetic underlayment system rather than shingling over the gaps.
Mature trees are the other McCandless factor. The township's tree canopy is one of the nicest in the North Hills and one of the hardest on roofs — leaf load in the gutters, moss and algae on shaded north slopes, and limb-strike risk in wind events. We install algae-resistant shingles as standard here and recommend guarded seamless gutters, since an unguarded gutter under heavy canopy clogs quickly.
We also handle storm and limb-damage repairs in McCandless, including tarping and insurance documentation for tree strikes.
Built for McCandless Weather
North Allegheny School District neighborhoods include both low ranches near the McKnight Road corridor and larger two-story homes closer to North Park. On the ranches, heat and moisture often collect beneath shallow attic spaces with blocked soffits. On steeper colonials, the recurring trouble points are chimney flashing, rear additions and shaded valleys. We inspect from inside the attic whenever access allows because stained decking, rusty nails and compressed insulation often explain a problem that is not obvious from the driveway.
Our McCandless replacement process is built for mature landscaping and older decks. We shield shrubs and air-conditioning equipment, remove all roofing to the wood and test questionable boards rather than covering them. Where plank gaps cannot reliably hold modern fasteners, the scope identifies re-sheeting before work begins. New membrane protects eaves, valleys and penetrations; algae-resistant shingles address the canopy; and balanced ventilation helps the new roof age evenly. Gutters are pitched and discharged away from foundations instead of treated as a decorative add-on.

McCandless Roofing FAQs
Do I need new plywood on my older McCandless roof?
Sometimes. Plank-decked homes from the 50s and 60s often need partial or full re-sheeting. We only charge for the sheets we actually install, and we photograph every board we replace.
Why is there black streaking on my McCandless roof?
That's gloeocapsa magma algae, and it's common on shaded North Hills roofs. Algae-resistant shingles prevent it; on a newer roof we can sometimes clean it without stripping granules.
A tree limb hit my roof — can you help?
Yes. We prioritize active leaks and storm damage and get out for an inspection as soon as we can, documenting the damage for your insurance claim.
