Flat Roofing in Corby, From the Garage Roof Up.
Most Corby homes have at least one flat roof: the garage, the dormer, the extension, the porch. We fit and repair them in GRP fibreglass, EPDM rubber and high-performance felt, surveyed free by drone before anyone quotes a penny.
Garage Roofs Are the Common Flat Roof Across Corby
Single garages sit on the side of half the houses on Corby's 1930s to 1970s estates, most still wearing their original felt.
Flat Roofing Work Across Corby
Flat roofing is where our "all aspects of roofing" claim earns its keep, and it sits alongside the rest of our Corby roofing work. Garages, dormers, porches, bay windows and kitchen extensions all have one, and on Corby's older estates they were almost all roofed once, in felt, in the same decade the house went up.
The pattern of failure is predictable. Felt membranes dry out, crack at the edges and split where the deck moves. Water sits in the low spots where the deck has sagged, and standing water does over a few winters what rain does in minutes. Edge trims lift, joints open, and one morning the garage ceiling shows a tide mark above the car. The good news is that flat roofs are also the fairest roofs to judge, because everything you need to see is visible from above. That is exactly what the free drone survey photographs.
If the membrane is past repair, we strip it back to the deck, replace any rotten boarding, and fit a modern system with the fall corrected so water runs to the outlet instead of pooling in the middle. Deck, trims, upstands and outlets are the four places flat roofs are won or lost, and they are the four places we spend the time.
Garage Roof Replacement in Corby
Ask in any 1950s to 1970s street between Danesholme and Oakley Vale and the story repeats. A single garage on the side of the house, felted when new, patched twice since, and now letting water into the corner above the fuse board. A garage roof replacement is usually a day or two of work, needs no scaffolding tower, and turns a space you avoid back into one you can actually use.
We strip the old felt and any rotten deck, fit new OSB boarding, and complete the roof in the system that suits it. Trims and drip edges are set so water discharges into the gutter rather than down the fascia, and the upstands against the house wall are dressed and flashed properly. If you want the work documented for insurance or a future sale, the before and after drone survey images are yours to keep.
GRP, EPDM or Felt? We Fit All Three
GRP fibreglass
A seamless, moulded finish formed over the deck. Ideal where the roof has upstands, awkward shapes or box gutters, and easy to inspect at a glance because the whole surface is one piece.
EPDM rubber
A single-sheet rubber membrane with very few joints. Suits simple garage and extension roofs, fits quickly, and involves no torch-on flames anywhere near your property.
High-performance felt
Modern mineral-finished felt systems are a long way from the old shed felt. Torch-applied or flame-free self-adhesive builds give garages, porches and dormers a tough, economical waterproof skin.

Frequently Asked Questions
Do you replace garage roofs as well as repair them?
Yes, both. A garage roof in fair condition can often be repaired for a few more winters, but when the deck is tired or the membrane has failed in several places a full replacement in GRP fibreglass, EPDM rubber or high-performance felt is the better spend. The free survey tells you which camp yours falls in.
Which is better, GRP fibreglass or EPDM rubber?
Both are excellent when fitted properly, and the right choice depends on the roof. GRP gives a seamless, moulded finish that suits shapes, upstands and box gutters. EPDM comes in large single sheets with very few joints, which suits simple garage and extension roofs. We will recommend the system that fits your roof, not the one we happen to have on the van.
My flat roof only leaks in heavy rain. Can it be patched?
Sometimes, yes. If the membrane is sound apart from one joint or puncture, a targeted repair will see it right. If water is getting through at several points, or the deck beneath has started to sag, patching becomes money down the drain and we will say so.
The puddle sits on my flat roof for days. Is that a problem?
It is worth taking seriously. Standing water slowly breaks down most membranes and finds the low patch where the deck has sagged. The free drone survey shows where water is sitting and why, and whether the fall can be corrected without a full replacement.
Can you survey a flat roof without scaffolding?
Yes. The drone photographs the whole surface, the edges, the upstands and the outlet positions without anyone leaving the ground. It is the same free survey we run on pitched roofs, and it is how we quote flat roofing work in Corby.
