Letterman & Sons | Roofing Services in Maryville, TN 37803

Absolutely. Adding a structure like a deck or an addition can alter airflow around your roofline, potentially exacerbating existing ventilation issues. At Letterman & Sons, we assess your entire home's ventilation system during the planning phase of any project. We ensure new constructions are integrated properly to maintain or improve airflow, preventing moisture buildup and protecting your roof's integrity.

A deteriorated deck can trap moisture against your home's siding and foundation, which can migrate and contribute to attic moisture problems. Our deck repair and replacement services focus on proper drainage, using moisture-resistant materials, and ensuring a gap between the deck and your home's exterior. This critical step helps manage ground-level moisture, reducing the overall humidity that can impact your roof's insulation and ventilation system.

This is a key consideration. When we construct your addition, we extend your home's roofing and insulation systems seamlessly. We prioritize continuous, proper attic ventilation over the new space and use insulation techniques that prevent thermal bridging and condensation—common culprits of moisture in our Maryville climate. Our goal is to make your addition as energy-efficient and dry as the rest of your home.
