Thinking of having your roof spray foamed? Think again...
Firstly, what really is spray foaming?
Spray polyurethane foaming (spray foaming
for short) is a rigid foam that is lightweight and in domestic applications is sprayed on to the underside of the roof at a thickness of approximately 50 to 100mm.
You may have been targeted by the hard selling companies who offer spray foaming services. They may claim to be roofing experts but many of these so called "experts" have zero experience in the roofing trade.
They will tell you that it's a fully breathable product...this is not true.
They will tell you that spray foaming is much cheaper than a re-roof...this is not true.
