Fort Wright Commercial Roof Repair Contractor

Wind across an exposed slope works on trim fasteners every gust, and daily heating and cooling of metal adds to it. Once a fastener backs out, the trim moves more, and the joint under it opens. Refastening with new screws fixes it before the trim lifts away.

Old sealant is cut out, the joint is cleaned, and new sealant or a joint cover goes on, with loose cleats refastened. The flashing under the cap gets checked, since water entering at the joint often damages it first, and any split is patched before the cap is closed up.

Clearing outlets, adding a downspout partway along long runs, and rehanging any sagging sections. Extending downspouts away from the lower walls keeps that runoff from pooling at entrances, and the gutter seams are sealed while the run is being reset.

It usually means loose trim, a lifted cap, or a flapping piece of flashing. Each of those opens a path for wind-driven rain, so it is worth a check before the next storm. Stay off the roof and describe where the sound comes from when you call.

They need the same materials, but they get checked more often. Wind-driven rain hits the slope-facing side harder, so cap joints, counterflashing, and the base of the parapet there are the first details looked at on each visit.

A check after every major windstorm is worth it, along with the usual spring and fall visits. Exposed trim and caps loosen a little at a time, and catching a backed-out fastener early keeps the trim from lifting and tearing the flashing beneath it.
