Asphalt shingles are one of the least expensive roofing materials, and they are available in a wide variety of colors.
Asphalt shingles are commonly used on sloped roofs, single homes, and smaller residential projects just to name a few. This material is very easy to install and provides flexibility during its installation process. Nowadays, shingles are also available with different textures and thickness, and they can be treated against mold and mildew.
EPDM roofing has become the most popular finish on flat roof garden offices over the last few years.
EPDM is a thick rubber sheeting which has been used extensively on commercial buildings for decades and has now been widely adopted by the garden office industry.
EPDM is laid in whole sheets so there shouldn’t be any joins in the system. Garden office suppliers usually attend a course on how to install the membrane, and they usually offer an extended warranty on the finish. EPDM manufacturers quote lifespans of 50+ years.
The edges of the roof are fitted with special kerbs, some of which include drip trims which direct moisture from the roof into the rainwater guttering.
EPDM has a dark grey / black appearance; some suppliers try to soften the presentation by adding a layer of stone chippings over the roof.
EPDM membranes are often part of the build-up of living roof systems
Many of the cheaper garden offices on the market, make use of steel insulated roof panels. These panels have been used in commercial building for decades and have become popular with garden office designers who like the speed of installation they offer and their material efficiency.
