Roof insulation works silently to make your living space more comfortable. It has been tested and found to reduce the overall cost of heating your house by an astonishing 13%! This type of insulation can also help to keep your house a great deal cooler during the summer months. That can add up to a nice amount of money in a few years time, perhaps even enough to pay for your roof insulation and installation!
There are two types of roof insulation. One of these types goes on the outside of your home in the area between the roof's shingles or tiles, and the sheathing used on top of the rafters as a place for the roofing. Normally, a type of foam board is stapled to the sheathing, and the roofing material is then installed on top of the foam board. This gives you a layer of protection from hot and cold air drifting into your home's attic and then into your living space. Rigid fiberglass insulation can also be used for this purpose. It is a lot easier to install this type of insulation when you are also replacing your roof shingles or tiles, but it can definitely be used on a roof that is already in place or a flat roof as well.
It may only be necessary to place roof insulation in your attic space, which some contractors will call loft insulation. This is the more common type of roof insulation, and you will find that more people have heard of this alternative. Rafter vents are needed to keep any build up of moisture from getting the insulation wet. Once this has been accomplished, the space between the rafters can then be filled with insulation.
Spray foam insulation is one choice that the homeowner has for roof insulation in their attic space. A smaller attic, such as one you cannot stand up in, is a good candidate for this type of insulation. Professionals spray the foam into all the spaces, cracks, and crevices, and it does an excellent job of keeping out air.
Another type of attic roof insulation is that familiar pink colored roll that looks a bit like a huge roll of carpet. These are known as batts, and are usually made of fiberglass, but can also be made from rock wool. The pink batts are flexible, and it is easy to cut and fit them into the needed spaces. It is best to leave this type of installation to a professional, for fiberglass can be rather tricky to work with. It is easy to get some of the fibers embedded into your skin, or even in your eyes. As you might imagine, this is quite painful, and potentially dangerous to your eyesight. There is also the risk of breathing in the glass fibers.
The various types of roof insulation that are available will make your home a comfortable place to live, whether it is winter or summer.
