We have extensive experience working with flat roofs, especially in commercial situations in both New Hampshire and Massachusetts.
Rubber Membrane – or EPDM (short for ethylene propylene diene monomer) is a popular choice for flat roofs. It’s very durable, is like an inner tube, and is attached with anchors or is usually glued down. This is often a great choice and survives the our harsh winters. See rubber roofing for more details.
Another popular type of flat roof is TPO, or Thermoplastic Polyolefin. This is a single-ply reflective membrane, and is made by fusing together ethylene-propylene rubber and polyprophylene. This is often a better choice than rubber roofing, lasts longer, requires less maintenance, and it is also lighter in color and as such reflects more of the sun, which helps with cooling efficiency of the building.
The third type of flat roof would be metal roofing. Durable and long lasting, metal is best used if the roof has a slight incline and is not completely flat. One of the downsides on a metal roof is when it is time to replace it, you usually have to do a complete tear out which adds to the long terms expense.
Older flat roofs will often use Built Up Roofing (BUR) or tar and gravel, which uses tar paper or fiberglass membranes. It was relatively inexpensive to install but is very heavy, and it is hard to find leaks should they happen. If you have an older tar and gravel roof that needs repair we can help.
