GDW Roof and Wall Systems


Flat Felt Roofing

There are several methods of flat felt roofing but we only use one product, this is the permatorch 4.5. This high protective performance torch-on system is designed to melt into your existing roofing felt giving even more added protection and leaving a hard decorative top finish it is easily the best all round performing roofing felt in its class. It can be applied to sloping flat surfaces and dorma sides.

On new build IKO Universal APP underlay should be installed for best results

If your flat roof has lost most of its protective grit and is showing dark patches it is time to act. The suns rays will cause the Bitumen to blister then the frost will attack causing the felt to crack. If you are in doubt, our roofer will visit you free of charge and give you his honest opinion on the condition.
