St. Catharines Winter Roof Prep Checklist

TL;DR

Prep a St. Catharines 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.

What actually fails on St. Catharines roofs in winter

It's not usually the shingles. In $St. Catharines 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.

The 10-point pre-winter inspection

  1. Full roof walk — note lifted, curled, or missing shingles.
  2. Every pipe boot: replace any with visible cracks or dry-rot rubber.
  3. All step and counter-flashing at walls, chimneys, and dormers.
  4. Ridge cap and hip cap nail set + sealant top-up.
  5. Gutter clean, hanger check, pitch verification.
  6. Downspout clear-out and extension in place (6 ft from foundation).
  7. Soffit vents unobstructed by attic insulation.
  8. Attic insulation depth check — target R-60.
  9. Bath fan and range hood terminations confirmed venting outside.
  10. Tree limbs within 3 ft of the roofline trimmed back.

FAQ — Winter Roof Prep in St. Catharines

How often should I inspect my roof in St. Catharines?+

Twice a year is ideal — spring (post freeze-thaw damage) and fall (pre-winter). At minimum, book the fall inspection.

My roof looks fine from the ground. Do I still need prep?+

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 St. Catharines.

Can you work on the roof in winter?+

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.

Is winter prep worth it if my roof is under 5 years old?+

Yes — the gutters, flashings, and boots fail well before the shingles do. A $189 inspection catches everything a new-roof warranty doesn't.
