How much it costs to replace a commercial roof depends on the type of roof you have and the size of your commercial property. Lots of commercial buildings have flat roofs, which are often made from felt, asphalt, EDPM rubber or fibreglass, while others are pitched roofs that might be made from tiles, shingle or metal.
It’s likely that your commercial roof will need replacing if it’s more than 25 years old. A roofer can carry out an inspection to determine what, if any, work is needed, but there’s a high chance that you’ll need a roof replacement if it’s that old. If your flashing is looking worse for wear or you’re missing a number of tiles or shingles, it might be time to replace your commercial roof.
So how much does it cost to replace a commercial roof? If your commercial roof is pitched, expect to spend between £4,500 and £7,500. It all depends on how large your property is and how easy access is, as the more scaffolding you need, the more it will cost. If your commercial property has a flat roof, the average cost would be approximately £4,500. Again, it all depends on the material, access and how large the roof is. Felt costs between £40-70 per square metre, while fibreglass costs between £80-110.
Whatever type of commercial roof you have or what it’s made from, make sure you get a few quotes from reputable roofing companies so you know that the job will be done well.
