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.

Answer: 
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.
