Frequently Asked Questions

What is Felt Made Of?

Roofing felt has come on leaps and bounds since its inception in 19th Century California, where it was used as a low-cost waterproofing solution. Roofing felt is generally composed of two primary elements, known as the base and the carrier.

The base is usually made from either natural or synthetic materials such as cellulose fibres or fibreglass, which is then saturated in waterproof bitumen known as the “carrier”. The carrier is what lends roof felt its weatherproof properties along with its ability to breathe effectively.

How Much Roofing Felt Do I Need?

The amount of felt you’ll need to cover your roof will naturally depend on its size. For example, if you’re just looking to re-roof a standard 4x6 garden shed, all you should need is one 1x8m roll of felt.

To calculate how much felt you’ll need, first measure the width and length of your structure at ground level. Then, multiply this figure by around 1.25 – 1.4 depending on how steep the pitch of the roof is. Finally, tack on an additional 10% to account for wastage. You should now know how many rolls you’ll need.
