Modern home construction typically features houses with garages facing the street. A two story home frequently has bedrooms on the second floor that extend partially over a two or three car garage. With July temperatures averaging around 94 degrees, Killeen roofing companies often deal with homeowners paying excessive costs for air conditioning resulting from hot air trapped in garages, creating an atmosphere similar to an oven that makes the upper level rooms much hotter than the rest of the house. The temperature in a garage can easily come close to 120 degrees, exacerbated when homeowners come home from work and park hot vehicles in the garage. Even rooms on the lower level with walls adjacent to the garage suffer from the effect of sun blazing on garage roofs. Homes that face west or south suffer the most, but even homes that face east or north do not enjoy immunity.

One of the approaches professional roofing companies take involves installing radiant barrier insulation beneath garage roofs. The science behind this approach simply addresses the issue by drastically reducing the heat generated by the sun striking the garage roof.

It involves a reflective barrier designed to prevent heat from getting inside the garage in the first place. Properly installed, a radiant barrier keeps the air inside the garage very close in temperature to the outside air.

Attic areas also represent good places to take advantage of radiant insulation barrier. The ceilings below the attic stay much cooler. The goal with an attic is to keep temperatures in a range of 10 to 15 degrees lower than they would be without the radiant barrier. The primary benefit results from a profound drop in the surface temperature of the insulation directly above the ceiling.

The two main types of radiant barrier insulation are radiant barrier paint and flexible foil. The superior flexible foil type of radiant barrier features a reflective foil surface similar to the aluminum foil found in the kitchen. The reverse side consists of a reinforced paper backing that resists tears and punctures. Installing this product in garages and attics is potentially possible by a homeowner, but the experience of a professional who has done it many times is worth the cost.

One other important consideration associated with radiant barriers that results in a dramatic lowering of air temperature in garages and attics involves adequate ventilation. Professional roofers do not ignore this part of the equation. They can assess the situation and make recommendations based on attic and garage ceiling area compared to the number and size of vents.
