Prep a Oshawa roof for winter in one visit: (1) clear gutters and downspouts, (2) inspect shingles and re-nail lifted tabs, (3) reseal all flashings and pipe boots, (4) verify attic insulation and venting, (5) trim overhanging limbs. Full-property winter prep runs $349–$749. Book by mid-October — post-first-frost lead time doubles.
It's not usually the shingles. In $Oshawa we see three failure modes drive 80% of winter roof callbacks: (1) pipe boots crack from UV and let meltwater in above the ceiling, (2) step flashing at the chimney or dormer pulls loose in freeze-thaw and wicks water down the wall, and (3) clogged gutters back water up under the first course of shingles.
All three are cheap to catch in October and expensive to catch in February.
Roof age and building style vary sharply across Oshawa. Below: what we prioritize in each neighborhood.
Twice a year is ideal — spring (post freeze-thaw damage) and fall (pre-winter). At minimum, book the fall inspection.
Yes. Pipe boot cracks, popped flashing nails, and clogged gutters are all invisible from the driveway and are the top three winter leak sources in Oshawa.
We do emergency leak and ice-dam work in winter. Non-emergency roof projects are scheduled around dry, above-freezing days — most sealants require ≥5°C to cure properly.
Yes — the gutters, flashings, and boots fail well before the shingles do. A $189 inspection catches everything a new-roof warranty doesn't.
