 Ventilation
Roof side ventilation prevents heat and moisture build up in the
attic. Trapped heat can radiate down into the home making the home
more difficult to cool. Moisture build up may result in mildew and
mold in the decking. Poor ventilation can also cause premature
deterioration of shingles.
Exhaust ventilation comes in two basic forms: natural airflow
ventilation (ridge vents, low profile vents, and wind turbines) and
power airflow ventilation (electric exhaust fans). Due to the
configuration of your attic one or both forms of exhaust ventilation
may be best. An evaluation of the ventilation system is a vital
element of a new roof system.
Underlayment
Quality underlayment (often known as felt or tar paper) protects
and beautifies your home at the same time. It helps prevent
wind-driven rain from infiltrating under your shingles and causing
damage to the home. At Ridgepoint we use high performance fiberglass
underlayment (hyperlink to http://www.atlasroofing.com/Residential/gorillaguard.asp)
on high pitch roofs. This product lays flatter and will not tear
adding to the beauty of the roof and protecting the installers
during installation. We also offer 15 lb. and 30 lb. felt for low
pitch roofs.
Shingles
Shingles come in a variety of styles and from various
manufacturers. The two primary types used in our market are the
standard 3-tab shingle and the more textured architectural shingle.
The 3-tab shingle is made of one strip of material and comes in 20
yrs to 30 yrs warranties. The 3-tab shingle is a flat product. The
architectural shingle is two strips of shingle laminated together
and comes in 30-years to lifetime warranties.
Another important aspect of shingles is wind resistance. 3-tab
shingles offer wind resistance from 60-70 miles per hour while
architectural offer 70-130 miles per hour.
Each manufacturer has its own colors and look. Shingles should be
reviewed for both technical and aesthetic value. In the southeastern
region it is wise to use only algae-resistant shingles. (Ridgepoint
installs only algae-resistant shingles.)
