Making More Room Of Your Roof Space
A dormer is a structural element of a building that protrudes from the plane of a sloping roof surface. Dormers are used, either in original construction or as later additions, to create usable space in the roof of a building by adding headroom and usually also by enabling the addition of windows.

Types of Dormer
Gable fronted dormer: the front of the dormer rises to a point at the ridge of the dormer roof.
Hipped roof dormer: the roof slopes back from front of structure to a point farther back, or, a dormer with a hip roof.
Shed dormer: A dormer (window) whose eave line is parallel to the main roof eave line.
Wall dormer: A dormer whose face is coplanar with the face of the wall below, breaking the line at the cornice of the building.
Eyebrow or eyelid dormer “A low dormer on the slope of a roof. It has no sides, the roofing being carried over it in a wavy line.” The bottom of an eyebrow dormer is flat and the top is curved.
Link Dormer A large dormer that houses a chimney or joins one part of a roof to another.
A dormer loft conversion is a structural extension which projects vertically from the plane of a sloping roof. By building a dormer onto an existing roof a cramped attic can be transformed into usable space thanks to the creation of additional headroom and floor space all bathed in natural light provided by dormer windows.
The most popular type of dormer conversion in the UK is a simple flat roof dormer. As well as being the cheapest form of dormer to build, a flat roof dormer also offers the largest amount of additional internal space. A shed dormer also features a flat single planed roof, but sloped downwards at an angle shallower than the main roof. Often used on homes with a gable roof, a shed dormer usually requires different roof sheeting to that of the main roof.
A gable fronted dormer or “dog-house dormer” is a more attractive option which consists of a gable wall extension built up to the existing ridge line, and a new roof section built outwards to the new gable end. Similarly a hipped roof dormer is an aesthetically pleasing option featuring three sloping planes of a hipped roof converging at the ridge of the dormer.
Rubber Dormer Roof
Dormer roofs can be awkward to access and installing a flat roof membrane can be a challenge even for the most proficient person. So you’ll want to be certain you’ve chosen the right flat roofing membrane for the job, and you certainly won’t want to keep making repairs over the years.
A one piece EPDM rubber roofing membrane is the perfect solution for dormer roofs. Proven to last in excess of 50 years and able to withstand the most extreme of climates, EPDM is durable, puncture resistant and won’t crack, rot or split over time. It’s also quick and easy to install. Plus it’s cost effective..
At East Coast Roofing, we recommend ClassicBond EPDM rubber roof to cover your Dormer Roof
Green Mineral Dormer Roof
Torch on felt flat roofing systems are laid on plywood decking comprise of 3 layers: a vapour control membrane, a thin layer of reinforced felt called the underlay and finally a thicker layer of felt called a cap sheet where the underside has been treated with a covering of bitumen. This bitumen covering is heated with a propane gas torch as the felt is unrolled and applied to the roof surface while it is still hot in order to weld all three layers together.
There are a few options regarding finishing touches:
The plain black bitumen finish is ideal for adding a solar reflective paint finish.
A mineral fleck finish is available in slate grey, green, brown and blue.
Walk way tiles can be added if your flat roof is positioned where you require pedestrian access.
Limestone chippings can also be applied.
All of our flat roofs are installed with mineral edging as standard which give a neat appearance by hiding the edges of the felt.
GRP (Fiberglas Polyurethane)
Continuous testing of glass reinforced plastic (GRP) roofs have shown that we should expect the laminate to last 50 years plus compared to the ten years a felted roof will last if your lucky, also as GRP Fibreglass roofs are cold applied the need to use dangerous tar pots and blow torches has been removed.
A GRP / Fibreglass flat roof is a single ply GRP laminate consisting of roofing resin and chopped strand mat reinforcement applied in situ over a good quality deck. The roof is finished with pre-formed GRP edge trims and a coat of pre-pigmented topcoat available in standard grey or any colour in the BS400 range.
