Insulated steel sheeting
Light, quick to fit, low maintenance and available with an insulation layer. A common choice for garages and workshops. It can be noisy in heavy rain unless it has a lining.
Non-asbestos fibre cement
Looks similar to the original, is rigid and long-lasting, and does not rust. Heavier than steel, so the structure must be able to carry it.
Tiles or slates
Best if you want the garage to match the house. Heavy, so the roof frame often needs strengthening, which adds cost.
Flat roof systems
EPDM rubber and GRP systems suit flat or very low-pitch garages. Quality depends heavily on workmanship and the deck underneath.
Things to settle before choosing
- Do you want insulation for a workshop, gym or office?
- Will you add rooflights?
- Do you plan solar panels? If so, tell the roofer early.
- What does the council require if you are in a conservation area?
- Does the structure need repair?
Ask for it in writing
Request a written specification, a guarantee on materials and workmanship, and a separate price for removal and replacement.
Prices are for the contractor to confirm after seeing your photos.
