Flat Roofs

Flat Roofs

There are several types of roofing materials available for any roofing project. If you had to come up with a way to make two large categories of roofing types, you would split them into the categories of sloped roofs and flat roofs. When most people think of roofs they imagine the typical pitched asphalt roof, but flat roofs have their place in the world too and most commercial buildings use flat roofs. Everything is less daunting when you have proper information on what you’re looking at.

More About Flat Roofs

Let’s review of what you need to know about flat roofs including the obvious and not so obvious differences between sloped and flat roofs and what to do when you have flat roofing issues.

Flat Roofs vs. Pitched Roofs

A sloped or pitched roof is a roof that has an angle to its pitch. In the roofing world slope is measured in 12-inch increments of rising over run, for example, a roof that rises four inches vertically for every 12 inches it runs horizontally is considered a 4/12 pitch roof. A flat roof, as the name implies, has no rise, it is considered a 0/12 pitch.

Sloped roofs have the benefit of gravity to help funnel precipitation and debris off the roof and into the gutter system and away from the house, but flat roofs don’t have this advantage.

Since water wants to hang out on flat surfaces like flat roofs, you need a different material to protect a flat roofing system from all that Mother Nature wants to throw at it. Examples of flat roofing materials include:

  • Membrane roofing
  • Modified rolled roofing
  • Built-up roofing
  • Metal roofing
