High Quality Flat Roofs in Kent
At Cousins Roofing & Building Ltd, we have been installing flat roofs for years. As such, we have much to offer our customers across Kent. Here is what you can expect from our team of roofers.

Building a
Base
Before we can install an effective flat roof on your property, we need something to lay it on. We build a structure of supporting timber or beams, over which we layer sturdy and robust plywood sheets. This gives us a foundation on which to layer the roof’s protective surface. We can also install sub-layer of insulation at this point.

Single-ply
Roof Solutions
The simplest way of finishing a flat roof is by using felts. Flat roof felts are impregnated with bitumen. This makes them both hard-wearing and waterproof – just what you need for a high-quality roofing solution. These felt sheets can be purchased as self-adhesive tiles for a single layer solution. This provides protection against all but the harshest weather conditions.

Three-ply Roof
Solutions
A single-layer of bitumen impregnated roofing felts is sufficient for many flat roof projects. However, many customers prefer a multi-layered solution. This gives you added protection against the elements, but also increases the weight of the roof. These felts can be applied as self-adhesive sheets, or bonded to one another using cold or hot bitumen.

No Job Too
Big or Small
At Cousins Roofing & Building Ltd, we never turn down a roofing project because of the size. Indeed, flat roofs are a popular choice for larger buildings, being more cost-effective that a pitched or tiled roof. Whether you want a small flat roof for your garage or a large one for an industrial unit, we can help.

Green Roofs
Flat Roof Specialists
Green roofs are an excellent choice for environmentally-conscious customers. Laid with the same care as a conventional flat roof, a green roof incorporates a layer of topsoil. This can be turfed or seeded to create your own living roof watered by the rainfall. Not only are they great to look at, they act as insulation, reducing your heating bills.

Domestic and
Commercial Flat Roofs
Flat roofs are popular among both our domestic customers and our commercial clients. Being quick and simple to install, these versatile roofing solutions are much in demand across Kent and the surrounding area. At Cousins Roofing & Building Ltd, we perform every flat roof installation with the same high standard of workmanship.

The Finishing
Touches
With the new roof installed, there is still work to be done. We need to install a roofline to protect the eaves and underside of the roof from damp and water ingress. This requires cut-to-measure fascia boards, soffits, and a guttering system. We also apply lead flashing to the roof’s joins to divert water away from these vulnerable areas.
