Spray Insulation Foam Can Transform an Aging Roof

Roof ageing can cause many different problems on a domestic property, which can sometimes lead to leaks and problems inside the house. Many people believe that the only solution is to completely strip and re-lay the roof in order to prevent these problems happening again, but they’re wrong. Spray insulation can make an old roof watertight again for a fraction of the cost of relaying. If you have any of the problems we have listed, please talk to us.

RoofWize UK Spray Insulation: Totally Maintenance Free

The insulating spray foam can be installed in one or two fuss-free days, with no disruption or mess. Within 30 days of completion RoofWize will supply a written transferable 30 year manufacturer-backed guarantee.

Spray insulation in the UK is a far more cost effective solution than many other forms of roof repair, and it’s a much cheaper option than relaying your roof. Every roof is different, of course, so to find out how much foam spray insulation will cost for your property, please ask us for a quote.
