Awards in roofing are a mixed bag. Plenty of them are pay-to-enter badges that mean very little once you look into who hands them out. The Confederation of Roofing Contractors is not one of those, which is why we're pleased about this one.
CORC named one of our GRP flat roofs their Roof of the Month for August 2026, in the flat roof category. The photo at the top of this page is the roof in question.
Who CORC are
The Confederation of Roofing Contractors is a UK trade body for roofing contractors. Membership isn't automatic, and it means a contractor has been vetted rather than simply having paid a subscription. We've been CORC members for years, and their logo sits alongside our other accreditations on every page of this site.
Roof of the Month is judged on submitted work, by people who fit roofs themselves. That's the part that makes it worth something. A roof can look fine in a photograph to someone who has never laid one. It's harder to impress somebody who knows where the corners usually get cut.
What judges actually look at
If you've never thought about how a flat roof gets assessed, the answer is: mostly the bits that aren't the middle. The large flat expanse is the easy part. What separates a good roof from an average one shows up at the edges.
- Detailing around penetrations. Vents, pipes and rooflights are where water gets in. Each one needs the laminate dressed properly around it, not just resin flooded near it.
- Upstands and terminations. Where the roof meets a wall or a parapet, the material has to carry far enough up and terminate cleanly. Skimping here is the most common cause of a roof failing early.
- Trims and edges. Straight, properly bedded, no gaps. This is the most visible sign of whether someone rushed.
- Consistency of the finish. An even topcoat with no thin patches, roller marks or missed areas.
- Falls and drainage. Water needs somewhere to go. A roof that ponds badly is a roof that will be a problem later.
Why any of this matters if you're choosing a roofer
Most people getting a flat roof quoted have no way of judging the work in advance. You can't inspect a roof that doesn't exist yet, and every quote will tell you it's a quality job. So you end up relying on proxies.
Accreditations are one of the better proxies, provided you check what's behind them. A useful question to ask any roofer: which bodies are you accredited by, and what did you have to do to get it? A contractor who has been vetted by a trade body, holds manufacturer approvals, and can point to work judged by other roofers is giving you something more solid than a promise.
The other reliable proxy is what previous customers say once the job is finished and paid for. Ours are on our reviews, unedited.
Same roof, same method
There's nothing special about the winning roof compared to the rest of our work, which is rather the point. It got the same treatment every job gets: deck prepped properly, fibreglass hand-laid as one continuous skin, detailing taken seriously at the edges, and a director on site rather than managing from a van somewhere else.
If you'd like to see more of what that looks like, our gallery has photos from jobs across Surrey, London, Kent and Sussex. Or if you want to know how GRP compares to what you've currently got, our guide on GRP vs felt vs EPDM is a good place to start.
Thinking about a flat roof?
We'll come out, measure up and give you a written, fixed price. It's free, there's no obligation, and if your existing roof has years left in it we'll tell you that instead of trying to sell you a new one.
