What local problems lead to a replacement in the Fox Cities?
Winter does most of the damage. Snow sits on the roof, heat from the house melts the bottom layer, and the water refreezes at the cold eaves. That cycle forms ice dams that push water under shingles. Over several winters it can stain ceilings, soak insulation and rot the deck along the edges.
Summer adds heat, wind and the occasional hail. Granules wear off, shingles curl at the corners, and sealant strips let go. Older homes close to the Fox River often have a second or third layer of shingles, which hides trouble underneath and adds weight. Newer homes in Grand Chute and Darboy can have a different issue, which is thin or poorly balanced attic ventilation that cooks the roof from below.
Common signs it is time to plan a replacement:
- Shingles curling, cracking or missing in many places
- Bare patches where granules have washed into the gutters
- Repeated leaks in different spots
- A sagging or spongy feel in the roof plane
- A roof approaching the end of its normal lifespan of roughly two decades for many shingles
