Setting the right budget

How much should you expect to pay?

We know it's difficult to estimate how much a project will cost, that's why we've surveyed our tradesmen to give you an idea of how much you should expect to pay for specific jobs. Tradesmen all across the country have contributed to the cost guides, so the costs you see are an approximate national average.

Where a dormer has been made from part of a main or extension roof then your tradesman will make sure that the roof will be sealed with waterproof flashing where it meets the building or any part of the roof. This will stop damp from permeating the building at this point and will ensure that your roof is watertight and long-lasting.

The roof on a dormer will be built in the same way as a flat roof for any part of the building and will contain waterproofing, insulation and a layer to stop vapour collecting in the roof space, all beneath felt. It is always worth using a professional roofer for these jobs and not cutting corners. The size of the roof will dictate the cost of the job, as materials and labour price will grow with the scale of the roof to be fitted. Your roofer should be able to advise you on materials used and give you choices on appearance, cost and finish.

Rated People asked 41 of our registered roofers across the country to give approximate prices for repairing roofs and for laying new roofs.

Please note these are average costs which vary according to the type of roof, the part of the property and the size of the property.
