Roofing

Here at Professional Building Supplies, we stock two types of high-quality flat roofing systems, PRO GRP & ClassicBond EPDM, as well as a variety of corrugated and polycarbonate sheets

For both systems, we sell kits on our website, with or without tools, for roofs with an area of up to 50m2. The individual components of the kits can also be purchased separately if you are in need of a few extra supplies. Both systems are resistant to extreme weather and are suitable for both domestic and commercial applications. We also stock Guardian's composite slate roofing system, a modern and innovative solution to tile roofing that features many benefits over traditional roofing tiles.

Whether you need a roof for your conservatory, carport, lean-to, or canopy, polycarbonate roofing sheets are the best choice. Our polycarbonate sheets are available in a Clear, Opal, Bronze, Bronze/Opal, or Solarguard finish. They are available in a range of sheet thicknesses, from 10mm to 35mm. For other outdoor projects, like greenhouses, shelters, canopies, walkways, pools, partitions, cold frames, or verandahs, you can use corrugated roofing sheets as they are more rigid, and require more precise cutting and fitting, and can block out sunlight. Our corrugated roofing sheets come in different materials, like stormproof, PVC, GRP, or bitumen. 

If you have a larger roof size than our base flat roofing kits provide for, or if you have specific requirements, please feel free to contact us, as we can provide something bespoke for you. We also stock skylights that go perfectly with a flat roof system; they can be purchased at one of our branches, or you can order them over the phone, and we can get them delivered within a 40-mile radius of our branches.
