Sunley Roofing, Inc.

Roofs are constructed with a single waterproof layer or a water resistant superstructure and a waterproof underlayment. There are many different roofing materials on the market to meet the needs of commercial and industrial clients.

The underlayment is an important part of the roofing structure, as it provides protection for the sheathing against any moisture. Roofing contractors usually use a heavy felt paper or a synthetic composite material.

Q: What are soffits? A: These are the areas underneath the balconies, the eaves, or the arches in your home or commercial buildings. You’ll want to keep an eye on them in case they need maintaining.

A tubular day-lighting device as small as 10” in diameter will provide light for up to a 150 square foot residential area. Of course for commercial purposes, acceptable illuminated areas will greatly vary due to ceiling heights and space issues, and the light output will also vary depending on the intensity of the sun.
