New Steel Garage Roof

Why steel

Pre-coated steel box profile sheets weigh very little, so they are kind to older garage timbers. They need little maintenance, shed water quickly and are available in a few colours. A well-fitted steel roof is also fast to install, which keeps the garage open to the weather for as little time as possible.

What affects the job

The size and pitch of the garage, the condition of the timbers and fixings, access, and whether you want insulation or an anti-condensation backing. Fascias, guttering and flashings at the wall are often replaced at the same time.

Old timbers that have been damp for years are the usual surprise. A good roofer checks them before sheeting over and tells you what needs replacing.

Is the old roof asbestos?

If the garage was built before 2000 and has corrugated cement-looking sheets, treat the roof as possibly asbestos until it has been tested. Do not drill, cut or break the sheets to find out. If it is asbestos, the new roof needs the old one removed first, and the steps are on the removal pages.

Common questions

Will a steel roof be noisy in rain?

Plain steel sheets can be noisy in heavy rain. An anti-condensation or insulated backing reduces the noise and also reduces drips from condensation.

How long does a steel garage roof last?

Coated steel roofing normally lasts for decades if it is fitted properly and not damaged, but the length of life depends on the coating, the colour and the local environment. Ask for the manufacturer guarantee, if one applies.
