When it comes to choosing the best insulation for the attic, homeowners often fall for many myths and legends. No brand of insulation is magic. Even natural, recycled or environmentally friendly products will not work properly if they are not installed by professional Elk Grove roofing experts who know what they are doing.

The goal of adding extra insulation to the attic or replacing the insulation that might have become moldy is to make the home more energy efficient, but that doesn't mean that extra insulation will produce more heat. The idea is to stop air and moisture from moving through the insulation.

There are three different types of insulation a homeowner can choose from. Which is best depends on where the insulation is going to go. There are also three methods of installation. Fiberglass and cellulose can be rolled or blown in and foam can be sprayed.

It is important to fill in the cracks around the crawlspaces, pipes, wiring and access panels before insulation is added or replaced. A reputable contractor will also plug any gaps in the soffit before installing the insulation.

The roofing contractors at Allstate Roofing of Elk Grove CA can assist you with any questions regarding storm damage or residential roofing.

It is not a good idea for homeowners to try to do this themselves as it has to be done properly. There cannot be any gaps. Insulation has to be firmly wrapped around pipes and wires where air may be able to get through.

While green materials, such as soy based foams advertised to be formaldehyde free, or cool cotton batting recycled from blue jeans, might sound healthy, if they are not installed without gaps and at the proper thickness, homeowners won't get any energy savings from using them. For that reason, a lot of roofing companies prefer to use products that are blown or sprayed in. They will fill up the spaces better and tuck themselves into the gaps to form a more efficient barrier than rolling out a batting would do.

If there are any incompletely filled areas where air can find its way around the material, it won't matter what the material is made of. It still won't insulate the attic properly. While batting can be done correctly if properly cut to fill the cavities in the ceiling completely, it is extremely difficult to make a tight seal around the house's wiring, framing, bathroom exhaust fans and other problem areas. Blowing cellulose into the attic that is made from recycled newspapers is often the better choice.
