Absolutely. Properly installed siding acts as a critical barrier. It seals the walls and eaves, preventing warm air from escaping and melting snow on the roof edge—a primary cause of ice dams. Our siding installation focuses on airtight sealing to reduce this risk and protect your roof deck.

Yes, you should. Roof deck rot often indicates moisture intrusion from the exterior. Faulty or damaged siding can be a direct source, allowing water to seep into wall cavities and up to the roof structure. We recommend a thorough siding inspection and any necessary repair or replacement to address the root cause.

Replacing old, worn siding with modern, durable materials significantly improves your home's defense. It creates a continuous, water-resistant envelope, blocking moisture from ice melt and rain. This protects not just your walls, but also helps maintain a dry, stable attic space above, reducing the risk of ice dams and structural rot.
