Facts About Spray Foam On Your Roof
Spray foam whose chief constituents are polyurethane bubbles enclosing a low-conductivity gas, has risen to the top of the popularity lists of insulating agents in recent times. But what is lesser known is its use as a roofing agent. Since it solidifies within moments of being sprayed to about 15 times its volume, it can even fill the most obstinate nooks and corners of your roof floor and insulate effectively. Polyurethane being very light weight aside from the gas it is enclosing, it doesn’t put pressure on the roof and maintains the structural probity of your house.
Its high reflectivity quotient also helps reflect back most of the heat and damaging UV rays. But in order to make sure the roofing lasts for a long time, careful handling is required as well as good maintenance. The roofing must not be repeatedly pelted with heavy windblown stones and other detritus which may cause dents to develop and heavy machinery or equipment must not be placed on it either since it could lead to unwanted fracturing and cracking. Once the foam has been put in its place by contractors, a good layering of elastomeric coating should be applied on it so as to protect the roof from harmful UV rays. The elastomeric coating should be replaced with a new one at an interval of 4-5 years to ensure longevity. Make sure the hired contractors spray foam on to the roof at a time when it is not too windy or foam could be blown off to other places which can be dangerous. After it has been installed without hitches, it is very safe to walk on as it can withstand a weight of up to 40 pounds per square inch.
How Much Does It Cost?
Spray foam roofing is possibly the most reasonably priced roofing agent of the lot and it gives good value for money by preventing the intrusion of hot or cold air into the interiors of your house. When compared to the cost of other roofing agents, spray foam will not lighten your wallet significantly but the expense will be more than what necessary for installing fiberglass or cellulose. Another teeny drawback to using spray foam is that if the installation is not a do-it-yourself project. Trained professionals with proper equipment and sufficient expertise are required.
The notion of spray foam as a lucrative roofing agent is rapidly catching up and is becoming very popular thanks to the bulk of information which is found on the internet about its uses.
