O'fallon Roofing | Roofing Services in St. Peters, MO 63366

Flashing lift is a common local issue often caused by wind uplift and temperature expansion. Properly installed siding from O'fallon Roofing creates a tight, integrated seal around roof edges and penetrations. Our expert installation ensures the siding works in harmony with your roof's flashing system, reducing gaps where wind and moisture can get underneath, which is a primary cause of flashing failure in our area.

Often, yes. In St. Peters, curling shingles and failing siding can share a common cause: trapped attic moisture from poor ventilation. When we assess your roof, we also evaluate your siding and soffit system. A full siding replacement with integrated, proper ventilation can be a crucial step in solving the root cause of your roof problems, preventing a recurring issue and protecting your entire home envelope.

The most urgent repair is to the siding directly adjacent to the roof's edge or chimney. Damaged or loose siding in these areas compromises the critical seal with the roof flashing. Our St. Peters team prioritizes these repairs to re-establish a weather-tight barrier, preventing water from driving behind the flashing during our heavy rains, which can lead to significant structural damage inside your walls.
