Indoor Thermal Comfort: Why You Should Let Your Roof Breathe

Monday, July 4th, 2016 by Stephen Campbell

Over the years, modern homes have evolved into some of the most airtight and insulated enclosures around. While these features have been helpful in curbing energy loss, thermal comfort has suffered a decline as a result. This refers to the satisfaction with the thermal setting inside a home.

Insulating Glass Wool

Its major determinants are our metabolic rates, clothing insulation, radiant temperature, air speed and relative humidity. All these depend on a single regulatory factor — proper ventilation. That's why every part of your home, including your roof, needs natural air flow inside and out. Patriot Roofing, the expert in roof ventilation and insulation in Tacoma, WA, discusses this concept in detail:

The Relationship between Air Leakage and Ventilation

To get the most from attic insulation, you need to restrict the amount of warm air that escapes from the living areas of your home. Obviously, erratic air leakage will ruin the efficiency of the insulation, so it's important to strike a balance. This way, you can keep heat loss to a minimum and eliminate condensation at the same time.

Ventilating Your Roof

Your roofing system "breathes" through the attic. The roof is the first recipient of solar heat, and a balanced airflow in the attic helps regulate the temperature between the interior and exterior of your home. This results in two key benefits:

  • Energy Efficiency - Proper ventilation works in tandem with your insulation in Tacoma to prevent hot, stagnant air from seeping through into other areas of your home. This way, your cooling system doesn't have to work for lengthy periods just to achieve your preferred room temperature.
  • Roof Life Span — Adequate air flow in the attic prevents moisture buildup that can eventually lead to mold, rot, and damaged roof shingles. To understand this better, imagine if you kept your hand in an airtight glove for a long period. When you take it out, the moisture buildup would make your skin look pasty and wrinkled. That's what happens to your shingles if your roof doesn't breathe properly.

As your trusted Tacoma insulation and ventilation experts, we will work with you to find the perfect balance between these elements, in your home.
