Cost guide: roofers

Our Which? Trusted Traders take us through roofing repair costs, and explain some of the signs that your roof needs repairing.

In this article

We’ve surveyed roofers¹ to find out how much you might need to pay for some common roofing jobs.

Our figures are only a guide to average costs, and there are several factors that can affect how much you’ll be charged, including:

  • where you live
  • the age and condition of your property
  • how long the job takes
  • ease of access to your roof
  • the type of roof tile or material being used
  • whether scaffolding is needed (as this can significantly increase the cost).

Ask roofers to break down the quotes they provide, so you know what you’re being charged for. Get at least three quotes to get a better idea of the going rate for your particular requirements.

Find trusted roofers near you. Only roofers who have passed an assessment by our trading standards professionals, and who follow our Code of Conduct, can become Trusted Traders.

Problems you should look out for

It's a good idea to have your roof and gutters inspected each year. Some contractors will carry out inspections free of charge, so ask about costs in advance.

You may be able to clear out gutters at lower levels yourself, to allow water to flow away and prevent problems, but most roofing jobs are best left to professionals.

It’s also worth looking up at your roof from time to time, as spotting early warning signs can prevent problems getting worse and becoming more expensive to fix. We’ve highlighted some early warning signs for different types of roof below.

Slate and tiled roofs

  • Internal damp or leaks: this may signal a cracked or slipped tile.
  • Missing tiles: if you notice a gap, get the tile replaced quickly to prevent water from penetrating the felt underneath. A gap can also make it easier for more tiles to be dislodged in high winds.

Flat roofs

  • Cracks or splits round the edges.
  • Uneven lumps.
  • Sagging: this may indicate that water has built up above.
  • Damp patches on the ceiling: this may signal that the roof covering has a tear.
