Frequently Asked Questions

Can new siding help prevent issues like roof flashing leaks in Genoa?

Yes, absolutely. Properly installed siding works in tandem with your roof's flashing system to create a continuous water barrier. In Genoa, where wind can lift flashing, damaged or improperly installed siding can expose these critical seams. Our siding installation and replacement services ensure a tight seal around roof edges and penetrations, providing an extra layer of defense against the moisture that causes skylight and flashing leaks.

I have a roof leak near my skylight. Do I need siding repair too?

Often, yes. Leaks near skylights frequently trace back to failed step flashing where the roof meets the siding. In many Genoa homes, compromised siding or its sealant is the entry point. Our process involves a thorough inspection of both the roofing and siding in the affected area. We repair or replace the siding as needed to ensure the flashing is properly integrated and sealed, fixing the root cause to prevent a recurring leak.

Why is siding replacement important for addressing lifted roof flashing?

Lifted flashing is a common issue here due to our weather. When flashing pulls away, it exposes the vulnerable gap between your roof and wall. If the adjacent siding is old, warped, or loose, it cannot support a proper re-sealing of that flash point. Our siding replacement service provides a straight, solid substrate, allowing us to re-install or replace the flashing correctly so it stays securely locked in place, protecting your home's interior from water damage.
