Attic Insulation


To evaluate your home’s energy usage and performance, Fortress Roofing offers a free insulation inspection of your home’s attic. Without a thorough inspection it is difficult to determine if your attic has enough insulation or even the right kind. Many of the products that were installed on homes in the past degrade and breakdown over time.

According to the U.S. Department of Energy: 65% of US homes, including most homes built before 1985; do not meet the current standard of insulation. The top causes of energy waste in most homes are inadequate insulation and air leakage.  According to Energy Star, a well-insulated attic can help you save up to 20% on your heating and cooling energy bills every year.

Our visit includes checking your existing attic insulation levels and immediately letting you know if you are losing money through inefficient insulation. An under-insulated home loses up to 40% of its conditioned air through the attic, costing you money.

Importance of Ventilation:

A well insulated attic without proper ventilation can actually be worse. We have observed homes that companies have covered up the ventilation and the result was a buildup of heat in the attic that “fried” a 30 year shingle in only six years. See our ventilation section for more information.

With energy costs rising, insulation becomes more important to home and business owners with each passing season. Whether to keep out the cold, or keep the cool in, maximizing your R-values can pay for itself many times over the lifetime of a building.

We have partnered with Owens Corning, the energy efficiency experts, to provide a unique new product called Atticat. We want to make sure our customers are maximizing their opportunities to save on the escalating cost of energy.

Is your attic costing you money?

All it takes is a quick peek to find out. If your attic floor is insulated but the wood beams (joists) are still visible, you probably don’t have enough. But even if you can’t see your beams, that’s still no guarantee that you have enough insulation. The best thing to do is measure. Ask us to have one of our our Certified Professionals from Fortress Roofing do a free attic insulation analysis.

For maximum energy efficiency, we recommend an insulation value of R-60 for attic floors – about 18 inches of insulation. Do you have enough?

atticat_insulationAdding insulation to your attic is a blast with the Fortress Roofing AttiCat® Insulation Blowing Machine! It conditions the AttiCat® Expanding Blown-In PINK Fiberglas™ Insulation by breaking it up and fluffing it, adding millions of the tiny air pockets that give the material its insulating power. The insulation is conditioned further throughout the length of the hose, and as it bounces its way up to your attic, more and more air pockets are added, increasing its insulating power even more. And since Fiberglas™ insulation will not settle, it will keep its energy-saving R-value over time.
