Roofs that are nearly flat or have a slight slope are called Low Slope Flat Roofs. All roofs need a slight slope to drain. To describe the slant of a roof, terms such as Low Slope or Steep slope are used. A low slope roof is one that has less than a 3 inch slope per foot. For every horizontal foot, the roof level goes up less than 3 inches.
A steep-slope roof (typically a shingle roof) that you see on most residential homes in Cypress, TX depends upon gravity to cause water to flow off the roof in one general direction so the water flows over the breaks & fasteners in the shingles until it flows to the edge. A low-sloped flat roof can’t depend upon gravity to shed the water in any particular direction so it must form a watertight, monolithic membrane that stays watertight all the way to the drains or edge.
Modern low-slope flat roofs tend to use a continuous membrane covering which can better resist pools of standing water. These coverings are applied as continuous sheets, bonded together with one or more heat-welding or adhesives applications. A more expensive low-slope flat roof can include sealed metal roofs using copper or tin. These are soldered interlocking systems of metal panels.
In the past a low-slope flat roofs would have used a built-up (“tar and gravel”) roof, but today this type of roofing suffers from performance, cost & environmental concerns requiring better value solutions.

Low slope flat roofs must perform well against wind, freeze-thaw cycles & UV radiation from the sun. A low-slope flat roof must also withstand expansion & contraction & remain 100% watertight. This requires well-engineered attachment with seaming & weathering characteristics to meet these performance demands.
