COMPOSITION SHINGLES


Composition Shingle Roofing San Jose, CA

Asphalt Composition Shingles
 
Composition shingles are the most popular material choice today for roof replacement and have been used on homes in the United States since the early 1900s. In fact, 80% of the homes in the US have an asphalt shingle roof. 
These shingles are available in a variety of designer styles, colors and weights, (The heavier the weight, the thicker the shingle). 
 
The core of the shingle is composed of a mat made of glass fibers and a special binder. 
The mat is saturated with asphalt to make the shingle tough and water-resistant. Next, small opaque granules are adhered to the asphalt to protect the shingle from the harmful ultraviolet rays of the sun. Made from crushed and screen rock, these granules receive a ceramic color coating which gives the shingle its color. 
 
Appearance - Thicker, heavier shingles tend to have a more pleasing ascetic appearance than the thinner, lighter shingles especially on roofs with a 22 degree slope or less. (22 degrees being the most common slope found her in the Bay Area). The extra thickness creates deep shadows from the sun across the roof surface providing a more enhanced, textured look. 
 
On steeper grade slope roofs, more of the shingle surface is visible from the ground. Here, the color shading and shadow lines incorporated into the shingles are more visible. Steeper sloped roofs with thinner, lighter shingles can be just as attractive as the thickener heavier versions. 
 
Walkability -Composition shingles are very easy to walk on, without the fear of damaging them and provide good traction, even when the surface is wet. They are also easy to work with should any repairs need to be performed, or adding new skylights, roof flashings, or solar array’s. 
 
Weight -2lbs. - 4.8lbs per sq.ft. The average house is constructed to sustain 700 lbs per sq.ft. 
 
Cost -Compositions shingles fall into the low - mid price range. The thickener heavier shingles, being more expensive. 
 
Energy – Poor. Asphalt shingles quickly absorb the sun’s heat and are slow to cool down. This results in heat radiating down thru the plywood deck into the attic.  
We offer various solutions to help remedy this problem such as the installation of a low E Thermal sheet radiant barrier and increase attic ventilation. (see Services > Energy Efficient Roof Solutions.
