When the water started dripping through my kitchen ceiling last autumn, I knew I could not ignore the roof any longer. My flat roof had been patched up twice before, and each time the problem came back. I was dreading the cost. But after doing my homework and making a few smart decisions, I ended up saving over £1,000 compared to my first quote. Here is exactly how I did it.
The Problem With Flat Roofs
Flat roofs are common on extensions, garages, and older homes across West Sussex. They are practical and cost-effective to build — but they do need proper care. Unlike pitched roofs, flat roofs collect rainwater rather than shedding it quickly. Over time, this causes the surface to crack, blister, and eventually let water in.
The biggest mistake most homeowners make? Waiting too long. A small leak that costs a few hundred pounds to fix can turn into a full roof replacement costing thousands if it is left alone. I nearly made that mistake myself.
My First Quote Was Eye-Watering
My first call was to a general builder I found online. The quote came back at just over £3,800 for a full replacement. I nearly fell off my chair. I decided to get more opinions before signing anything.
That decision alone saved me a significant amount of money.

What I Did Differently
- I contacted a specialist, not a generalist.
There is a big difference between a general builder who “does roofs” and a dedicated flat roofer. When I called High & Dry Roofing, the difference was immediately clear. They asked the right questions, explained the options in plain English, and gave me a detailed breakdown of costs rather than one big number.
Specialists tend to work more efficiently, use better materials, and waste less time — all of which keeps the price down.
- I got the roof properly assessed before agreeing to anything.
Rather than assuming I needed a full replacement, High & Dry Roofing came out and inspected the roof properly. It turned out that a large section was still in good condition. Only part of the roof needed replacing, along with some work on the upstands and drainage. A general builder had assumed the worst without even getting up there for a proper look.
- I chose a modern roofing system.
I went with a GRP fibreglass roof, which High & Dry Roofing recommended over the old felt system. Yes, it costs slightly more upfront than a basic felt replacement — but GRP lasts 25 years or more and requires very little maintenance. Felt roofs, by comparison, often need attention every 10 to 15 years. Over the long run, GRP works out far cheaper.
- I did not rush into the cheapest quote.
The lowest quote I received was tempting, but it offered no detail on materials or warranty. A cheap job done badly will cost you far more in the long run. I chose value over price, and I have not regretted it for a second.
The Final Result
The work was completed in two days. My new roof is clean, solid, and fully guaranteed. The total cost came in at £2,750 — more than £1,000 less than my original quote, and a much better job.
