Flat roofing in High Wycombe in Firestone EPDM rubber, GRP and felt
Flat roofing in High Wycombe for garages, kitchen extensions, dormers and porches, in Firestone RubberCover EPDM, GRP fibreglass or felt. Every flat roof we fit is fully guaranteed. Ring 01494 292776 for a free quote.
Flat roofs fail at the edges first. The felt splits where it turns over the drip, water ponds in a dip in the deck, and the boards underneath go soft. A patch on top buys a winter. Stripping the old covering back to a sound deck and putting the right system on it lasts.
For small residential roofs we install Firestone RubberCover EPDM: one sheet of rubber membrane with no seams across the middle of the roof, made for garages, extensions, dormers, porches, carports and balconies. Where you want a hard, jointless finish we lay GRP fibreglass, which is stronger than felt and easy to repair if it is ever damaged. Felt is still there when the budget calls for it.
Removal of the old covering, new decking where it has rotted, maintenance and repairs are all part of the service. Dermot's Google review of his garage roof: "Pat and his team were very fast and efficient with there work and all for a great price."

Flat roofs: your questions answered
How much does a new flat roof cost in High Wycombe?
A single garage or porch runs about £1,000 to £2,500 and a rear extension of 15 to 20 square metres about £2,200 to £4,800 around High Wycombe, depending on the system and the state of the deck. Our flat roof cost guide breaks it down.
Which is better, EPDM or GRP?
EPDM rubber is one flexible sheet and suits most small residential roofs. GRP fibreglass gives a hard, jointless finish that takes foot traffic. Pat explains both on your roof and prices each.
Can my flat roof be repaired instead?
Often, yes, if the deck is sound and the damage is local. If the deck has gone soft, a repair will not hold and Pat tells you so.
Are your flat roofs guaranteed?
Yes. Every flat roof we fit is fully guaranteed.
Do you replace the boards underneath?
Yes. Any rotten decking is cut out and replaced before the new covering goes on.

What our customers say
I recently had a complete new re-roof done by Safe Tech Roofing, and I honestly couldn’t be happier with the result. From start to finish, their professionalism was spot on. They explained everything clearly, provided a fair and detailed quote, and stuck to the agreed timescale. The team worked incredibly hard, kept the site clean and organised, and showed real attention to detail throughout the entire job. The quality of workmanship is excellent, the new roof looks fantastic and gives me complete peace of mind knowing it’s been done properly. You can tell they take real pride in what they do. Reliable, skilled, and trustworthy, I would highly recommend Safe Tech Roofing to anyone needing roofing work done. Top company. Top job.
Safetech Roofing completed a number of repairs to the roof and loft space in my house, as well as the installation of an internal support element for a partially removed chimney stack. The work was done to a very high standard and at the agreed quotation, which was good value. A council building control officer then inspected and passed the structural element of the works. When some queries were raised by building control, Safetech went above and beyond to help resolve them. The suggestions made by Safetech and their team all the way through were extremely knowledgeable and practical. They also actively discouraged me from carrying out unnecessary expensive work, and instead suggested a lower cost, simpler solution, which the building control officer then agreed with. Additionally, the scaffolding had to be left in place far, far longer than expected - this was due to delays on my side and Pat generously didn’t charge extra for this
Really happy with the roofing work done for us. The team were professional, friendly, and kept us informed throughout. The job was completed on time, exactly as quoted, and the workmanship is excellent. They left everything clean and tidy and made the whole process stress-free. Reliable and trustworthy, would definitely recommend.
We contacted the service about a roofing issue at our home and he came out the very next day to take a look. Even though the job was small, he was willing to take it on without hesitation. The work was handled professionally and in a timely manner. It’s not always easy to find someone who responds quickly and is willing to help with smaller projects. Highly recommended!
I engaged Safetech Roofing to undertake the re-pointing and removal/replacement of the lead flashing around my chimney which was leaking. Since the work has been completed the leak has been fixed. Pat and his team were reliable, professional and were able to fit me in at short notice. I’m very pleased with the work they’ve carried out and would highly recommend.
