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.

The roof that sits over your bay windows is very much like a small half roof. It slopes upwards to an apex, where it joins your property and is built in a similar way to an actual roof, although in some cases, such as newer properties, this may be a single pre-made unit.

If you need a new slate or tiled bay window roof you will probably want this to match the design of your house’s main roof. This will dictate a main part of the cost of the job, with the rest being dictated by how large the roof is and therefore how long it will take to build. The roofer will take down old tiles first and replace any felt as necessary. They will then lay the new tiles or slate and attach flashing where the roof meets your property and begins to slope downwards. This will mean that both your wall and the roof will be watertight and there will not be problems with any run off causing damp. The bay roof will also have its own guttering added.

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