Low sloped roofs are commonly called flat roofs. That and folks who look for a bargain are the reason that low sloped roofs have a bad name. This is one roof that you do not want to scrimp on. You also want to make sure that the roof drains and has a minimum of 1/4” in 1’ fall with no pending. If your roof if flat you need to change the pitch or you will get a short life out of the roof. Low sloped roofs are roofs below 4” in 12” and 2” in 12” changes specifications on almost all materials

The types of  roofing material for low sloped roofs are

BUR, TPO, Modified Bitumen, PVC, Metal, EPDM  Shingles (down to 2” in 12”) and Vegetative

 

BUR = Built Up Roof System comes in 3 types.

 

All 3 consist of a base sheet for movement and separation from the building. Ply sheets which are set in heated asphalt or tar (in our area it is asphalt) and a top layer (protective). This layered system built upon itself thus the name. these systems are specified by the manufacture, not roofers, make sure you are getting a actual specified system.

 

Aggregate which is gravel top coating—the aggregate is place on top to protect it actual roof from the sun and also pulls water away from the roof with capillary action. The disadvantage is it is harder to find a leak in this style of roof.

 

Cap sheet which is finished with a layer of roll roofing called cap sheet or reflective foil

 

Coated which is coated with a liquid membrane, which can be metallic, white or even black in color. It is best to go with a reflective coating on this style of roof in Southern California
