Galvanised steel roofing sheets offer an outstanding combination of strength, longevity and value. Used across agricultural, domestic and commercial buildings for generations, they remain one of the most reliable and widely specified roofing materials available – and one of the most practical replacements for ageing asbestos garage roofs.
Corrugated galvanised steel is one of the most versatile roofing materials available, suitable for new builds, re-roofing and over-cladding existing structures. It performs equally well on agricultural barns, garden outbuildings, garages and commercial units – and it’s one of our most recommended solutions for replacing asbestos cement garage roofs, offering a durable, cost-effective and long-lasting result.
A key option worth considering is anti-drip felt backing. This anti-condensation lining is bonded to the underside of the sheet and prevents moisture from forming and dripping inside your building – a common issue with unlined steel roofing, particularly on garages and outbuildings. It’s a straightforward upgrade that makes a significant difference to the performance and comfort of the finished roof.
At Weather Shield North West, we supply and install galvanised steel roofing across Bolton, Greater Manchester and the wider North West. With over 20 years of industry experience behind us, we know how to get the installation right first time – no shortcuts, no callbacks.
A galvanised sheet is only as good as the installation behind it. Correct overlap, pitch-appropriate fixing, sealed end laps and properly fitted flashings and trims are what separate a lasting roof from one that causes problems within a few years.
This attention to detail matters especially when replacing an asbestos garage roof. Getting the transition right – from safe removal of the old material through to a correctly installed steel system with anti-drip felt backing – is what ensures a clean, weathertight result that won’t give you problems down the line.
Our experienced roofing team handles every job from initial survey through to final sign-off, making sure your steel roofing system is watertight, structurally sound and built to perform through whatever the North West weather throws at it.

Weather Shield North West Ltd. did an outstanding job for my mother-in-law in Bury. They replaced an old cathedral roof on her conservatory with a new solid roof. The tradesmen were first rate, friendly and competent. The quality of the job is better than we could have wished for. The price was highly competitive as well. Everything about this job was great and I recommend this company unreservedly.

I’m extremely happy with the window work that was done. The crew was professional, on time, and paid great attention to detail. The windows look amazing—clean, clear, and perfectly finished. They respected my home, cleaned up after themselves, and made the whole process easy from start to finish. I would definitely recommend them to anyone needing new windows.

Had 6 windows and back door fitted. Josh and Johnny were excellent. Very quick and efficient. The work is very neat and tidy. Cleared the mess up after themselves and are a couple of nice fellas. More than happy with the results. Would recommend this company to family and friends and would certainly use them again for any future work.

We had our conservatory roof internally cladded by Weather Shield North West Ltd and it’s one of the best home improvements we have ever made. The price was fair the materials used top quality and the fitting crew were extremely professional and did a fantastic job with a great craftsman finish. It’s been a great investment turning our conservatory into an all round the year room. Cant recommend them enough.

Weather Shield North West have just completed insulating the inside of the conservatory roof in one day. The work done is excellent. The guys who fitted and also the electrician were outstanding. They were respectful and polite from start to finish. They also cleared all the waste materials and they cleaned up the little mess that was made. My wife and I cannot praise them highly enough. Thanks for the efficient planning from the very beginning. We had been worried that the work would make the conservatory darker, but we are happy that it hasn't. It has made the conservatory look much more modern. Thanks very much. Very highly recommended!
