We finished a full flat roof replacement on a rear extension here in Chatham in July 2026, and the whole job is photographed below, including the part under the old covering that nobody wants to find. Free inspection, fixed written quote, 24hr callout.
A rear extension in Chatham with a flat roof that had reached the end of its life. We took it back to the joists rather than laying yet another layer over the top, and what was underneath made the case on its own: a saturated deck and several joists that had rotted through.
Completed in July 2026 and covered by our company workmanship guarantee. The customer was up there with Cornelius when it was signed off.




Walk any Chatham street and the front elevations look after themselves: pitched roofs, tiles, a ridge line that has been there for decades. It is the back of the house that quietly rots. Rear extensions, outriggers, kitchen lean-tos, garages and porches nearly all carry flat roofs, they are out of sight from the pavement, and nobody climbs up to look at them until there is a mark on a ceiling.
By that point the water has usually been in the deck for a long time. Felt is cheap to lay over the top and that is exactly why so many of these roofs have three or four coverings on them already, each one hiding the state of the one below.
We would rather open it up, show you what is there and price the real job. If it can honestly be repaired, we will repair it. If the timber has gone, no covering on earth will save it.
Flat roofs are what brought us to Chatham, but we work on everything above the wall plate, pitched and flat alike.

Leaks traced properly. Failed upstands, split coverings, tired flashings and slipped tiles fixed at the cause, not sealed over at the symptom.

A roof that is quoted from the ground is a guess. We inspect properly, and if the deck or the joists have gone you will hear it from us before you commit, not halfway through.
