VM Zinc Anthra plus warm hip roof with Zinc fascia, soffit and external square box gutters. This job did not have traditional down pipes. Instead we installed Scandinavian style chains.

Which Materials To Use For My Shed Roof?

It’s important to select a good material that is waterproof and can brave the elements. These can include felt, wood, bitumen sheets and plastic tiles. Below we examine the best materials for shed roofing with installation tips.

Plastic Shed Roofing Tiles

Plastic shed roof tiles are becoming a popular option for re-roofing your garden shed. These tiles are very lightweight which will reduce the weight on your shed. The plastic tiles overlap and interlock which makes it impossible for water to enter.

Each plastic tile strip only requires three screws to fix them to an overlapping strip. The ridge tiles are very flexible which makes them ideal to adapt to different pitches.

When using plastic roof tiles you will need to install dry fixings for the tile edges. This will help to keep the roof watertight and stop pests entering your shed.


If you are looking for a low cost material that is easy to fix then shed felt may be the option. This is the most popular solution for garden sheds currently. Anyone with a little experience should be able to cover their roof with felt.

You can buy many different colours to blend in with your shed and surrounds.

Clay Roof Tiles

Clay tiles can add a lot of character to your shed roof and blend into the local surrounds. This is a popular material due to it’s vast ranges of colours and sizes. One of the downsides of using Clay tiles is they tend to be heavy in comparison to other materials. It’s important to ensure that your shed structure can support the weight. Of course there are many ways to reinforce the structure to support the extra weight.
