When the summer months begin to roll around and Colorado temperatures begin to spike, many homeowners begin to notice a “blistering” effect on the exterior of their shingles, which is usually a direct result from an under-ventilated attic. The heat from an under-ventilated attic can make the shingles so hot from within that “blisters” begin to form on the exterior of the shingles, damaging the roof. The best way to avoid the “blistering” effect is to make sure that your attic is well-ventilated!
Another downfall to a poorly-ventilated attic can be added pressure to the home’s cooling units; this can raise the cost of your monthly bills while simultaneously wearing out your cooling system.
It is estimated that 9 out of 10 homes in North America do not have proper attic ventilation, simply because most people are unaware that attic ventilation can impact the longevity of their entire home!
Along with the “blistering” of shingles, high utility costs and damage to cooling systems in the home, you may also see premature aging of your entire roofing system, warping and cracking of your wood framing as well as damage to siding, paint or wallpaper.
Proper attic ventilation systems allow a continual flow of outside air through the attic, protecting the efficiency of the insulation and helping to lower temperatures. A well-ventilated attic should have 50 percent intake to 50 percent exhaust, keeping the equilibrium steady. It is also recommended that you use one type of vent in your entire attic, avoiding vent combinations because the mechanics of different vent types vary. Rather than combining styles, use complimentary styles that work with one another to keep your ventilation effective and efficient.
