Installing a new roof on an extension requires the same skill and expertise as fitting any kind of roof and this work should be undertaken by a professional roofer. An extension roof is any part of the roof that juts out or extends from the main body of the roof. This could be due to the design of the house or over an addition to your home.

The extension roof is often like a mini version of the main roof and will be sloped in the same way, with its own apex. It will need felt laying and then tiles or slate laid over this in the same way as a main roof and it will also need flashing in places to make it watertight. The size of the extension will dictate the size of roof and therefore the cost of the job overall. The materials used will, in most cases, be made to match the style and design of the main roof.
