Six things to do before the snow arrives, and why ice dams cause more damage than the snow itself.
Winter puts a roof to the test. Snow, ice and strong winds cause real damage if the roof is not ready for them. A few proactive steps now will save you a repair bill later. Here is the checklist.
1. Clean the gutters
The simplest protection there is. When gutters are clogged, melting snow and ice cannot drain, and that is what creates ice dams — water backing up under the shingles, leaking through, and damaging the interior. Clear the debris before the snow starts, or fit gutter guards so it does not build up again.
2. Schedule a professional inspection
Something small — loose or cracked flashing — becomes major damage during a winter storm. An inspection finds the vulnerabilities before freezing temperatures and heavy snow arrive.
3. Trim overhanging branches
Snow-laden branches over a roof are a hazard. As snow accumulates they snap, and they take shingles and gutters with them. Walk the property and cut them back.
4. Insulate the attic
Proper attic insulation regulates roof temperature, which is what stops ice dams forming. Ice dams happen when snow melts on a warm roof and refreezes at the cold edge, backing water up under the covering. Insulation also keeps the building warmer and cheaper to run.
5. Do not underestimate wind
Winter storms loosen shingles, dislodge flashing and can lift whole sections of roof. Inspect for weak spots and missing material now. A roofing team can secure those areas to take the season's wind.
6. Do not let snow accumulate
Heavy snow puts real load on a roof — sagging, and in extreme cases collapse. If you see significant build-up, rake it off from the ground. For larger accumulations get a professional in rather than going up there yourself.
Why it matters
Your roof is the building's first line of defense against winter weather. Without preparation, minor issues escalate into leaks, ice dams and structural damage. The preparation is cheap; the alternative is not.
