Pre-Winter Roof Prep Checklist for NJ Homeowners

Every January we get calls from NJ homeowners with ceiling stains, ice-dam backups, and active leaks that could have been prevented by a 20-minute inspection in October. The patterns are predictable — and so is the fix. Here's the pre-winter checklist we recommend to every Tri-State client.

1. Clean every gutter and downspout. Leaves and acorns trap water that freezes into ice plugs. Once a downspout freezes, water backs up against the fascia, finds the path of least resistance, and ends up inside the wall. Hand-clean every section, flush downspouts with a hose, and re-secure any loose hangers before temperatures drop.

2. Check the attic from below. Climb up with a flashlight after dark. Look for daylight pinpricks through the deck (active leak path), darkened insulation (chronic moisture), or frost on the underside of the deck on cold nights (inadequate ventilation). Each of these is a winter problem in the making.

3. Inspect flashings around chimneys, skylights, and vents. Caulk dries out and cracks. Step flashing pulls away from masonry as the building moves with temperature changes. Any failed seal here becomes a leak the first time wind-driven rain or melt water finds it.

4. Verify attic ventilation. Soffit vents must be unblocked by insulation, ridge vents must be clear, and the soffit-to-ridge air path must work. Inadequate ventilation causes ice dams more reliably than insufficient insulation does.

5. Walk the roof from the ground. Look for missing shingles, lifted edges, or granule piles in the gutters. If you find any of these, get a professional inspection before the first storm.

6. Have a tarp and bucket ready. Even with prep, storms happen. Knowing where your emergency supplies are matters when a leak shows up at 2 AM. Better — save our number in your phone now so you don't have to look it up under stress.

Twenty minutes in October. Don't skip it.
