A new roofing system is a huge investment, whatever the material, so it is a good idea to learn as much as possible about the roof type that you are planning to use before you buy the materials and start the installation process. Here are some terms that you should familiarize yourself with:
- Components of sloping roofing systems – sloping roofs are composed of roof covering, such as shingles, tiles, slate or metal sheets and underlayment meant to protect the boards or sheet metal underneath, called sheathing, which rests on rafters and trusses that make up the roofing structure. Roofs also have flashing to reinforce the areas around skylights and other openings and vents to ensure ventilation;
- Components of flat roofing systems – flat roofs are different from sloping roofs not only in terms of shape, but in terms of the layers it consists of. The topmost layer is usually a layer of granules or gravel that keep the rest of the roof in place and protect it from the elements. Underneath the granules comes the base layer, consisting of sheets of felt, tar paper or membrane, then the protection board that separated the topmost layers from the insulation underneath the protection board. The roof insulation rests on a vapour barrier mounted on top of the roof deck. Like always, if installed by a professional Shelby roofer, your roof will last for a long time.
