Essex County is no stranger to high winds. From northeasters that pound the coast and drive inland to severe thunderstorm downbursts that sweep through the Watchung foothills, wind events are a regular threat to every roof in our service area. Knowing what wind damage looks like helps you assess your roof quickly and accurately after any significant wind event.
Visible Wind Damage Patterns
Wind damage on asphalt shingle roofs follows predictable patterns. The first areas to fail are along eaves and rakes where shingle edges are most exposed to uplift forces. Missing shingles in these locations are often the first sign of wind damage. Ridge caps are the next most vulnerable, as they sit at the highest point where wind speeds are greatest and the shingles are attached differently than field shingles.
Lifted or creased shingle tabs indicate wind got underneath and bent the shingle without fully tearing it off. These creased shingles will not lie flat again because the fiberglass mat inside has fractured. Even though the shingle remains in place, it has lost its waterproofing integrity at the crease line and will eventually leak. This type of damage is easy to miss from ground level but is obvious during a rooftop inspection.
On the windward side of your roof, look for a pattern of bare spots where adhesive strips have released. Modern architectural shingles use thermally activated adhesive that bonds tabs together, but sustained high winds can progressively break these bonds. Once several shingles in an area have lost adhesion, each subsequent wind event does more damage because loosened shingles create lift leverage on adjacent shingles.
Wind Damage Beyond Shingles
Wind does not just damage shingles. Check for displaced or damaged flashing at wall-to-roof transitions, loosened vent caps, and shifted gutter positions. In Essex County, the copper and aluminum flashing on older homes is particularly susceptible to wind fatigue from repeated northeasters. Metal fascia covers, drip edges, and rake trim can also separate from the structure during high-wind events.
Debris impact from wind-driven branches is a separate but related concern. Even small branches driven by 60+ mph winds can puncture shingles, dent metal components, and crack flashing. After windstorms in the heavily treed neighborhoods of Maplewood, South Orange, and Verona, branch debris on the roof surface should be removed carefully and the area beneath inspected for impact damage.
Wind damage is progressive -- each event makes the next one worse. Addressing wind damage promptly stops the escalation cycle and preserves your roof system integrity through subsequent weather events.
