There are three main types of flat roof installation: built up roofing, single-ply flat roofing, and spray on roofing. A built up roof is a system of multiple layers or membranes such as Modified Bitumen. Single ply roofing is the most common flat roofing material on the market today. It is typically installed as fully adhered/glued, or mechanically fastened. The most common types of single ply roofing are EPDM rubber roofing or TPO (thermoplastic polyolefin) roofing. 




These include tile, slate, and cedar materials. 




Roof tiles are designed mainly to keep out rain and are most commonly made from concrete or clay. A large number of shapes (or “profiles”) of roof tiles have evolved over the years including:

  • Flat Tiles – The simplest type which are laid in regular overlapping rows.
  • Mission or Barrel Tiles – Are semi-cylindrical tiles laid in alternating columns of convex and concave tiles.

Roof tiles can be fire and impact resistant and provide natural water shedding. Tile roofs have been proven to withstand sustained winds of over 100 miles per hour.




For light, commercial, or industrial siding needs we offer aluminum, steel, vinyl, fiber cement and cedar materials to accommodate the building design, aesthetics and functionality that you are looking for.





Commercial buildings are larger and therefore need a better gutter system than residential properties. The styles, sizes and durability differ and depending upon city regulations, they are required to meeting different building codes. The commercial gutter systems also come in a variety of materials: aluminum, steel, copper, EPDM-lined and box guttering to maximum drainage.
