FAQ

What is a short and complete shingle definition?

A shingle is a lightweight bitumen roofing material composed of a reinforcing material (usually a fibreglass mat) embedded in asphalt, with a coating finish made of granules. 

The bottom of each asphalt shingle is cut for aesthetical purposes. Several shapes are available: rectangular, beaver, triangular, hexagonal...  

They must be installed on a full deck (not a discontinuous structure), waterproofed protected by a bitumen membrane like ONDUTISS  STRONG. Their installation is made recovering flat and uncut part of the previous shingle. See BARDOLINE  roofing  shingle  installation  page to know more about shingle installation. 

The quality (and therefore its durability) of a shingle is linked to the weight of the fibreglass mat and the quality of the granules.
