McPhail Siding And Roofing Company | Roofing Services in Windham, NH 03087

Absolutely. Compromised siding can allow wind-driven rain and moisture to seep behind your home's exterior walls. This trapped moisture can migrate upward, eventually saturating the roof sheathing (deck) from the sides and underneath. McPhail's expert siding repair and replacement services seal your home's envelope, preventing this moisture intrusion and protecting your roof structure from the rot commonly seen in our local climate.

Proper siding installation is crucial for protecting critical flashings. When old siding fails or is improperly installed, it can expose metal flashings—especially where the roof meets sidewalls or chimneys—to constant moisture and debris. Our meticulous siding replacement ensures tight, correct integration with existing flashings, providing a protective barrier that diverts water away and significantly extends the life of your flashing, combating the rust issues prevalent in Windham.

Often, yes. Roof deck rot typically indicates a prolonged moisture issue. Our inspection process looks holistically at your home's exterior. The source of the water damaging the roof deck could be failing siding higher up on the wall or at the roof-to-wall intersection. We frequently find that addressing both the damaged roofing components and the contributing siding issues, through repair or targeted replacement, is the most effective, long-term solution for Windham homeowners.
