How Much Roofing Felt Required

[237SJ]

The people who delivered my shed managed to omit the roofing felt and nails. After 3 weeks of trying to get that out of them, I`ve decided to get the felt myself and send them the bill as they are so hopeless. The woman there says that a 10m roll will do it. Is that correct? The shed is 8' x 6' pitched roof.

You'll need between 5 and 6 square metres. There's 10 sq.m on a roll, so there'll be some left over.

just make sure the nail's you get aren't too long better to be a little short than too long,probable get a few longer one's in where you have the roof braces,take your time

Thanks The Builder. I thought I`d check here as I don`t trust them!

[237SJ]

Thanks fishing81. I`ve managed to get the nails out of them (despite being told they sent them two weeks ago - they arrived today)

Unless I'm typically misunderstanding seemingly common terms between the U.S. and the U.K., SJ... are the people providing the shed and the felt also providing roofing shingles?

Here in the U.S. the felt (also called tar paper) is used for an underlayment for the shingles (or other final finish roofing material) but won't hold up very well used just as roofing... just wondering...

Thanks!

Hi Clanad. She told me to get 20kg green mineral roofing felt. When we took the old shed down, there was a covering that was sort of bitumen with rough bits on it (a bit like coarse sandpaper). I think that was all that was on there and I`m assuming this is what it is.

[Clanad]

Aha! I understand now SJ... we have the same thing here in the U.S. Rolls of 'tar paper' onto which an additional layer of asphalt and various colors of gravel have been applied. We use to use it on our chicken house when I was a kid.

Acceptable, but generally much lower quality than asphat shingles layed on a layer of "tar paper".

Good luck!

Clanad, it is traditional to have leaky shed roofs in the UK, thats's what the nails are for.

Clanad, the shingles are used a lot in the US, but very little over here. Our shed felt is made from bitumen, same as shingles. Tar paper is quite a different thing :o)

Buy the felt made with polyester - it'll last and last.. Cheaper felt is made using jute, which will eventually rot over time.

Roofing felt, commonly called tar paper, is an important component of any roofing system. It provides the roof with additional waterproofing and protects the wood sheathing of a roof until the installation of shingles is complete. Building codes and shingle manufacturers typically require the use of felt.
