Rated 5 out of 5 by from Best felt available I have always used this felt, strong and watertight, cuts easy and is extremely strong, lightweight to carry up onto the roof, the wider roll (1.5 mtr x 50 mtr ) is extremely handy to cover the roof quickly, excellent price for the amount on the roll

Rated 5 out of 5 by from Tough as old boots. Very strong and durable membrane. If you want to do a quality job then use this. Easy to work with and will tolerate stainless steel staples to fix to rafters. I have gone over to this from tyvek. Shame there is not a reflective alternative.

Rated 5 out of 5 by from Protect 'felt' roofing product Good as the main brands and just as easy to use. A little expensive given it is not one of the main brands. On low pitch roof I suggest using 2 or 3 layers to stop any capillary action.

Is this a replacement for the felt under roof tiles?

Asked by: Aid1473
Hello Aid1473, Yes, this breathable membrane would be installed under the roof tiles in place of a traditional felt. If you are in any doubt about which membrane is right for your job, we would recommend consulting a roofing professional. Thank you for using Q&A

Is this suitable for a shed roof?

Asked by: Nawaz
Hello Nawaz, There's no reason if installed correctly that this would be an issue. It will still have the same water resistant properties as it would for a normal roof. Any further installation queries would have to be directed to a suitably qualified trades person. Thank you for using Q and A.
