What causes roof leaks in Scranton homes?
Leaks here follow the local housing and the climate. Some of the most common causes:
- Ice dams. Snow melts on a warm roof, runs to the cold eave and freezes. Water backs up under the shingles and leaks into walls and ceilings.
- Flashing at chimneys. Many older Scranton homes have brick chimneys, and the metal and mortar around them wears out.
- Flat and low-slope sections. Row homes and porches often have rubber or tar roofs that crack and pond water.
- Aging slate. Slate itself lasts for decades, but the nails and flashing do not.
- Poor attic ventilation. Trapped heat and moisture shorten the life of the decking and shingles.
After a heavy wind or snow, check ceilings and attic corners. A small stain caught early is a small repair.
