As the summer months approach, heat and humidity can impact your home’s roof. These conditions reduce the shingles’ lifespans and damage roofing materials. Below, learn about potential harm due to moisture and how to prevent it.

How Heat & Moisture Damage Roofing Materials

Rising humidity levels increase the moisture in your attic, which can permeate roof decking and weaken it. The dampness damages shingles, curling them at the edges and making them more prone to blowing off during storms. Even if the roofing materials are not compromised, the humidity increases the chance of mold and mildew, which can lower the home’s air quality.

The wood rafters, joists, and decking that support the shingles will expand as temperatures rise, putting stress on the roof’s flashing. If the flashing cracks, it can let water into the attic, increasing the chance of mold and mildew issues. Additionally, heat rising from inside the house can blister shingles, especially if the attic isn’t ventilated to let heat escape.

How to Protect Your Home

Adding ventilation to your attic has multiple benefits. The air circulation through the attic will carry heat and moisture out of the house, preventing condensation on your roof decking. Additionally, your air conditioning system will function more efficiently if hot air is already vented out of the home. Adding ventilation is not a complicated process; a roofing professional can inspect your roof and recommend the necessary intake and exhaust vents for the structure.
