The roof needs stable temperatures to maintain its shape and dimensions. During summer, heat from the sun gets trapped inside the attic, causing it to increase in temperature. Extreme heat deforms the roofing material and misaligns the sheathing and rafters.

Good attic ventilation is a system that removes warm air and takes in fresh air from the outside. This venting system achieves stable attic temperatures and prolongs the lifespan and performance of roofing materials.

Here is everything to know about attic insulation and ventilation.

The Benefits of Attic Ventilation and Insulation 

Stable Attic Temperatures

Warm air will expand sheathing and rafters, causing structural misalignment. The trapped air can also travel from the sheathing to the roof material. Asphalt shingles with high temperatures expand and split if left unattended.

Reduced Mold Growth 

Mold grows in dark and damp places. High attic humidity will encourage mold growth and cause the attic's wood components to rot. Ventilation with dehumidification ensures a dry attic with reduced to zero mold growth. 

Save Energy

You can reduce your HVAC expenses with excellent insulation. All rooms will have equal and stable temperatures without increasing your thermostat settings. Lower settings with introduced comfort are a must for any home.

How to Construct an Efficient Attic Ventilation System

Attic ventilation should adapt to the needs of the home and the shape of the roof. Effective ventilation can remove all the heat produced indoors and has enough vents of the best quality. Here are a few ways to improve it with the help of professional roofers.

Objectives

Every attic accumulates heat in various ways. A hot ceiling upon touching your hand indicates that it's storing too much hot air. Ice buildup on the roof is due to hot air stored in the attic. A roofer can help you determine the best attic ventilation design to achieve excellent heating and cooling. As a rule of thumb, one square foot of attic ventilation per 300 square feet of ceiling space is optimal.

Roof Vents

Attic peak roof vents remove hot air rising to the peak of the roof. These vents are optimal for hot air reduction rather than cool air intake. Roof ridge vents work well with soffit vents, achieving excellent attic air insulation.

Soffit Vents

These vents help outside air to enter the attic from below. They achieve smooth airflow with ridge cap vents. A rectangular soffit vent has wood beam openings and is enclosed with vents. Continuous venting has the system built from the soffit to the attic area.

Gable Vents

Gable vents are at the ends of a roof and have controllable openings that help dissipate heat. These vents work best with ridge caps and soffit vents. 

Fans

Attic exhaust fans remove heat actively from the roof. Advanced attic exhaust fans have temperature sensors to detect the optimal times to remove heat. On the other hand, affordable ones use switches to turn on and off.
