Insulation is necessary to protect the roof from weather getting into the cracks of the wood shingles on the roof. If left alone for a long time, this can cause some damage on the roof. Installing foam plastic on these cracks will protect the roof from further effects of weather.
It is in liquid form, which expands several times its initial size when sprayed on a surface. The spray foam is polyurethane foam or SPF that is used to insulate almost anything. It is advisable to get professional assistance in installing the foam roof although it could be relatively easy to install. SPF is not at all affected by moisture and it traps heat.
This is great when you have really high ceilings and you dont want to have expensive electric bills. SPF could trap humidity though, so you really need to be careful when youre doing the installation by yourself.
You have to make sure that the surface on which you will be spraying the foam roofing kits is ultra dry and that there are no contaminants like solvent or oil that can affect how the liquid will adhere to the surface. It will be best to do the installation during summer to make sure you have a really dry surface.
While many DIY foam roofing kits are available, take the time to research how to apply spray foam roofing kits. Foam roofing is a major source for insulation because of its superior quality to strengthen the roof and its thermal efficiency. When applied to a roof surface, heating bills are decreased by about 70%.
