How Does Good Attic Insulation Improve Your Roof?

Want your roof to reach its maximum lifespan? Schedule regular roofing maintenance, and improve your attic insulation. Excellent attic insulation prevents several issues that shorten the lifespan of asphalt shingle roofs.  

Keep reading to learn how excellent attic insulation improves your roof’s lifespan.

Prevent Ice Dams

Good insulation prevents uneven temperatures on your roof, which can cause ice dams to form during winter. The cold and warm sections of your roof will repeatedly melt and freeze snow, creating ice dams that could leak into your attic.

Ensure Good Ventilation

The hot air inside your house will rise to the attic and remain trapped there. Then, it would slowly descend back into your living spaces because it has nowhere to escape. You can prevent this problem with excellent insulation and a well-designed and properly installed attic ventilation system. Attic insulation slows heat transfer and works hand in hand with roof ventilation to extend your roof’s lifespan. Be sure to discuss these components with your contractor when requesting a roof estimate. 

Preserve the Roofing Structure

A humid attic that previously suffered water damage creates an environment where mold can thrive. Mold colonies will eat away at the wood components of your roofing system. Fortunately, proper insulation reduces the heat and humidity levels in your attic, prevents the growth of mold colonies and preserves your roof’s structural components.

Extend Your Roof’s Lifespan

Attic insulation and ventilation reduce humidity and maintain stable temperatures in your attic and on your roof. With minimal exposure to heat and moisture, you can expect your asphalt shingles to last through their estimated lifespan.
