In the aftermath of storms that frequently batter the UK, many homeowners have woken to find their sheds a little worse for wear. Those needing to make a quick repair face a bewildering choice of roofing felt, online or in store. If you’re looking for the Best Shed Felt, then read on.
Roofing felt for sheds can be divided into three broad types: Shed Felt, Heavy Duty Shed Felt, and Super Shed Felt (Polyester Reinforced). For simplicity, this guide steers clear of professional grade roofing felts (those designed primarily for professional installation) and self-adhesive roofing felt. Pricing and installation techniques of these are often beyond the reach of the general D.I.Y. enthusiast.
Super Shed Felt / Polyester Reinforced Shed Felt
This shed felt is considered by many experts as the best value for money. Super shed felt will normally outlast both standard and heavy duty felt. With a life expectancy of 15 years, the major improvement comes from the use of polyester fibre as the core ingredient, rather than cloth fibre. This significantly increases both tear and wear resistance, as well as life expectancy.
Pricing of some polyester reinforced shed felt has come down in recent years. In addition to it lasting longer than most heavy duty shed felts, expect to see it retailing cheaper too! A real bargain in our books!

Shed Felt Adhesive used in conjuncture with clout nails will prolong the life of the roof.
Using too many nails can cause as many problems as using too few.
In colder months where roofing felt becomes harder to work, store the felt indoors 24 hours before installing. Do not use in temperatures below 5°c.

Shed Felt is used on most garden buildings across the UK, this is the one you are most likely to encounter in D.I.Y. stores and garden centres. This article will give you a brief shed felt comparison. So when you’re picking your materials, you’ll know what to look for.
Good quality shed felt is made from a compressed cloth-fibre base, which is then covered with modified bitumen. During manufacture, the felt is coated on one side with a coloured mineral finish.
The fibre-base provides the strength, flexibility and tear resistance of the roofing felt, whilst the bitumen provides the waterproofing. The mineral finish prevents the bitumen from melting in the heat of the sun – and is coloured to create a pleasing finish.

Shed Felt Comparison
Most standard / premium shed felt is designed with a life expectancy of 5 years in mind. As with all building supplies, there are different grades available – buyer beware!
Quality and life expectancy change in relation to the quality, type of fibre and the weight of materials used in manufacture. Cheap shed felts and Value brands (and those imported from outside of the UK) generally use lower quality raw materials in order to save costs.
Often the cloth fibre found in premium brands is replaced with matted card fibre. Experts say that this reduces the tear resistance and makes the felt harder to bend around the edges of the shed without the shed felt cracking.
To save costs further, less materials are used. Cheap shed felt may weigh much less than a standard 18 kg roll. Expect lighter, value or cheap shed felt to last considerably less than standard or premium grades.
Heavy Duty Shed Felt is a bitumen fibre felt, but one that is typically manufactured with twice the amount of materials to that of a standard shed felt.
Apart from being twice as thick as normal felt, the other noticeable difference is that the green mineral finish is made with coarser grains (2-4 mm).
Heavy Duty roofing felts are not specifically designed for sheds. They were originally designed as the tough top sheet on a two layer flat roof system, but are used where a longer life expectancy is sought.

Different companies use different names to bring their product to market. Expect to see it called Garage Felt or even Trade Top Sheet. A good heavy duty felt will weigh around 35-38 kg and have a life expectancy of 10 years (twice that of a premium shed felt). Not surprisingly, expect to pay double the price!
