Roofing guides and costs
Straight answers to the questions we get asked on Hertfordshire roofs, written by the roofer who does the work.
Every guide here answers a question Hertfordshire homeowners ask before they book a roofer: what will it cost, and does it need doing now. The prices are typical Hertfordshire market ranges for 2026, the same ranges you will find on our service and town pages. Use them to budget and to check a quote. They are not our price list: your price is the free written quote Kieran gives you after he has seen the roof.

How to use these prices
Where your roof sits in a range comes down to its size, how it is reached, the material and what is found once the work starts. A ladder job on a two-storey semi sits at the bottom. Scaffold, a steep or three-storey roof, slate or clay tile, and rotten timber under the old covering push it up. A quote far below the range usually leaves something out, such as scaffold, lead or the skip, and a quote far above it should explain why. Whoever quotes, ask for it in writing, with each part of the job listed.
