Roof Systems

Examples of Roof Pitches

A low-slope roof, commonly referred to as a flat roof, has a slope of 3/12 or less

A steep-slope roof also referred to as a pitched roof has a slope of 4/12 or more

Recover or Tear-Off?

All steep-slope roofs must be removed before installation of the new roof.

In some instances, the new low-slope roofing system can be installed directly over the existing roof. The option to recover is dependent upon building codes and condition of the existing roof.

In most cases, installation of a Spray Foam Roof does not require removal of the existing roof.
