Roof Vents at Carter Lumber

Understanding The Importance Of Roof Vents To A Well-Ventilated Attic

Ventilation is one of the most critical factors that determine the durability of a roofing structure. Without roof vents, heat and moisture can build up in an attic area, causing rafters and sheathing to rot, shingles to buckle, and insulation to lose its effectiveness. Check your local Carter Lumber for roof vents and other roofing supplies.

Here are a few things to look for that indicate a need to improve ventilation:

It is important never to block off sources of roof ventilation, such as louvers, ridge vents or soffit vents, even in winter.
Excessive surface granules in gutters or downspouts; granules give shingles added weight and protect them from ultraviolet rays.
Indoors, look for cracked paint, discolored plasterboard and peeling wallpaper as signs of damaged roof areas.
Proper attic ventilation helps prevent structural damage caused by moisture, increases roofing material life, reduces energy consumption and enhances the comfort level of the rooms below the attic.

Determining Ventilation Requirements

The requirements for proper attic ventilation may vary greatly. It depends on the condition of the attic and the part of the United States in which the roofing structure is located as well as the exposure to the sun, shade and atmospheric humidity. Nevertheless, the general ventilation formula is based on the length and width of the attic.

Insulation

Insulation plays a key role in proper attic ventilation and comfort in a home. Proper insulation helps provide uniform temperature, noise reduction and moisture levels as well as energy efficiency.
