A flat roof is only as good as what sits underneath it, so this Kingston job started at the deck. We installed new plywood decking to give the roof a firm, flat base, then built the waterproofing up in three layers, bonded one over the other so the laps never line up and there is no single point for water to find.
That built-up approach is the traditional way to make a flat roof properly watertight: each layer backs up the one below it, and the finished membrane is thick, tough and stable. A new polycarbonate roof section was installed as part of the same job, bringing natural light through while keeping the weather out.

Flat roofs fail from shortcuts underneath, not from the surface you see. Here is what this build-up gets right.
New plywood gives the waterproofing a firm, flat base. Laying a new membrane over a tired deck is how flat roofs sag, pond and fail early.
Each layer is bonded over the last with the joints staggered, so there is no single seam for water to exploit. The result is a thick, tough, stable membrane.
The new polycarbonate section brings daylight through the roof while staying sealed against the weather, fitted as part of the same job rather than an afterthought.
