Flat roof work in Luton: replacement and repair in torch-on felt, GRP fibreglass or EPDM rubber. Reliable Roofers Ltd strips the failed covering, replaces rotten decking, corrects the falls and finishes every edge and upstand properly, on garages, rear extensions, dormers, porches and bay windows across the town.
Luton has thousands of flat roofs, and most of them were never meant to last this long. The garages on the post-war estates in Sundon Park, Lewsey and Farley Hill were felted once in the 1960s. The rear extensions added to the terraces of Bury Park and High Town over the last 40 years were felted by whoever built them, and the dormers on the loft conversions across Stopsley and Round Green have felt or mastic-asphalt cheeks that are now cracking. When they fail, the deck under them is usually rotten too.
We replace the roof, not just the covering. Old felt off, soft boards out, new OSB3 deck with proper falls to the outlet, insulation where the room below is heated, then felt, GRP or EPDM depending on the roof. Rooflights and lanterns are built in and sealed as part of the job. A garage or a single-storey extension is normally one to three days.
For your flat roof in Luton, explain how you use the space below before choosing a covering. A heated kitchen extension in Bury Park needs insulation considered alongside waterproofing. A detached garage in Lewsey presents a different brief. Include rooflights, wall junctions and any areas that collect water when you describe the problem.
The shape matters too. Compare a broad, open garage roof with a small extension squeezed between walls. The second has more junctions relative to its area. On a Stopsley dormer, reaching the roof adds another consideration. Those differences explain why a price based only on roof size leaves out essential parts of the job.
Before a replacement surface goes down, the old layers are removed so the deck can be examined. Soft boards are replaced with suitable OSB3 or ply. The direction of drainage is then established through the supporting falls, using firrings or tapered insulation to address ponding. You need this foundation settled before the waterproof finish is installed.
For a warm roof, insulation sits above the deck beneath the covering. Tell us whether the room is heated and whether its ceiling already shows damp. The survey brings those observations together with the roof inspection. Photographing the exposed layers records the preparation that you cannot inspect once the new finish covers it.
Torch-on felt uses a built-up covering with a mineral cap sheet. GRP forms a seamless fibreglass finish around the roof's details. EPDM provides a rubber membrane suited to a simple expanse. Your comparison should include each system's edges, wall upstands and drainage outlets alongside the main surface.
Ask for the chosen material to be named in your itemised quote. Deck replacement, insulation, rooflight work and access all contribute to the final cost. For a rear extension in High Town, show us how boards and stripped waste will travel between the roof and the collection point. Discuss passage width and gate access before work is booked.
Set aside a few days for replacing a garage or single-storey extension roof. Extra deck repairs and intricate rooflight details add work to that schedule. Tell us about daily access you need beneath the roof, including garden doors and garage entrances, so the working arrangements are clear.
At completion, review the outlet and upstand photographs as well as the wider roof view. Retain the specification with your invoice. Afterwards, watch for leaves collecting at drainage points and arrange clearing before a blockage develops. Report persistent standing water or an edge pulling away. Keep your checks to a safe viewing position and ask us about access for any maintenance.

Tell us what the roof is doing. A photo of the outside and of any damp inside is usually enough for a price range.
We find the cause, not the stain, and tell you whether it is a repair or a replacement.
Itemised, with materials named and dates set. Nothing starts until you have it.
Our own team does the work, photographs each stage and leaves the site clean.
For a garage or a simple extension, felt is good value. For a roof with rooflights or that you walk on, GRP. For a large simple roof you want to forget about, EPDM. We quote the one that suits and an alternative to compare.
If the deck is dry and sound, yes: splits, blisters and lifted trims can be repaired. If it is soft underfoot, replacement is the honest answer.
Yes, most weeks. A single garage roof in felt or EPDM is normally a one-day job.
For most house extensions and garages, torch-on felt is good value and lasts well when it is laid properly. Choose GRP where you have rooflights, awkward shapes or foot traffic. Choose EPDM for a large, simple roof where a single sheet can cover it. We quote the option that suits the roof, and an alternative if you want to compare.
Often, if the deck is sound. Splits, blisters and failed laps in felt, and lifted trims, can be repaired. If the deck is soft or the felt is generally perished, replacement is the honest answer.
The covering has to connect with the walls that rise above it. Those upstands and their flashings are part of the waterproofing, alongside the outlet and exposed edges. On an extension between neighbouring walls, ask to see each junction identified in the specification so you understand the work included in your price.
Explain whether you want to retain the existing rooflight or fit a different one. Show us any staining around the opening and include the upstand in photographs taken from a safe position. The rooflight arrangement belongs in the agreed specification because its connection to the covering is part of the replacement work.
