Roofing FAQs

The cost depends on the property size, roof type, and materials. A full re-roof on a three-bedroom terrace using slate or concrete tiles typically ranges from £4,000 to £9,000. A GRP flat roof on a rear extension or garage costs £1,500–£4,500 depending on area. Hills Roofing Ltd provides free, detailed written quotes. Contact us for an accurate figure for your property.

Most pitched roof replacements on a standard terrace or semi-detached take 2–5 days. Flat roof installations on extensions are often completed in 1–2 days. We confirm the expected duration in your written quote before work begins.

In most cases, replacing a roof with the same or similar materials is permitted development and does not require planning permission. However, if your property is in a conservation area, is listed, or you want to significantly change the roofing material, you may need consent. We advise on planning requirements during the free survey.

All new roof installations come with a written workmanship guarantee. GRP fibreglass roofs carry a 20-year guarantee. Bauder flat roof system installations include a manufacturer's product warranty. The specific guarantee for your job is confirmed in writing before work begins.

Often yes. If the flat roof membrane has localised damage, such as a split, blister, or failed seam, a targeted repair is the correct approach. If the membrane is extensively deteriorated or over 20 years old, full replacement is usually more cost-effective. We give an honest assessment after inspecting the roof; we won't recommend replacement when a repair will genuinely solve the problem.
