Hole in the roof
“Gavin from GT Roofing was brilliant. He came promptly, was good with comms all the way through and he did a great job repairing a hole in the roof. Reasonable rates and I would absolutely recommend”
Helen Northcott ★★★★★
New GRP roof, rear extension
“Gavin and his team completed a new GRP roof for our rear extension. Can't fault Gavin's knowledge and experience and quality of work. One of the key points which is often overlooked with building work at your property is the level of care and consideration given to your neighbours during the building period. Nothing but positive feedback from neighbours during and post the work, would recommend.”
Steve King ★★★★★

Quote the same day
“Gavin and his team were responsive to my enquiry in the first instance. Came at the agreed time to do the Quote. I had the Quote the same day and they were able to start the job when it suited me. Always very polite, explained what the job entailed and when any issues arose they told me how they were going to continue. I was 100% satisfied overall and would happily recommend them.”
Katy Jones ★★★★★
Damp, not the roof
“Gavin was extremely helpful. He came to look at our roof very quickly and when this proved not to be the cause of the damp in our house, didn’t charge us for this visit. He has previously done repair work on our roof and chimney stack, which we are very pleased with. I would recommend him.”
Fiona Dunger ★★★★★
Flat roof repair

05 · Questions people ask Gavin

Can you come out quickly for a leak?

Ring 07917 663303. Urgent repairs are done the same day wherever possible, so the water stops getting in.

Will you just tell me I need a new roof?

No. We look at what's actually wrong and price that. Plenty of roofs need a repair, not a replacement, and we'll tell you which yours is. Quotes are upfront with no hidden charges.

Do you do flat roofs?

Yes, in GRP fibreglass, felt and rubber. Extensions, porches, garages, and repairs to blistered, split or ponding roofs.

Do you do chimney work?

Yes. Repointing, new flashing, repairs to the stack, and taking down chimneys that are worn out or no longer used.

How long does a new roof take?

Usually 3 to 4 days, depending on the size, how fiddly it is and the weather. We assess it properly first so you know before we start.

Are you insured?

Yes, we're fully insured, for domestic and commercial work.
