Asphalt Shingle Roofs
Advantages & Disadvantages
Most detached single-family dwellings and multiple dwellings with sloped roofs are covered by asphalt shingles. For multiple dwellings, this is the prime choice for cost reasons. Asphalt shingles primary function is for waterproofing and to hold granules in place, adding to the overall strength. Asphalt shingles have improved over the years to stay more flexible during their lifetime. Shingle roofs are among the easiest and fastest to replace.
Shingle Roofs Advantages
Shingles require little maintenance and can be easily repaired or replaced when damaged.
Economical, Light Weight and.Ease of Installation:
The weight of asphalt adds to the ease of installation. The lighter weight makes it easier on the sheathing and compatible with most sloped roofing systems. The reason why shingles are economical is because they are made of light material that is easier bared by the roof structure itself.
~ Aesthetics and Decor:
Shingles come in various colors and textures that are suitable to blend in with house decor. Shingle roofs can be installed to look like natural cedar shakes or tiles. An expensive look without the high costs associated with these other materials.
Shingles have the capacity of cost-effective manufacturing in high volumes. Labor costs to install per bundle or per square foot are cheaper than installing other materials.
Shingle Roofs Disadvantages
Restriction on Installation:
Shingles need to be installed in warm temperatures, cold weather installs can cause future problems and get easily damaged if installed at temperatures below freezing. Asphalt is sensitive thermostatically and if exposed to poor ventilation, can be damaged.
Thermostatic variations cause shingles to expand and contract. In extreme thermostatic variations shingles do not fare as well because they can exceed their linear expansion limits. Extreme temperature variation can cause shingles to deform and crack.
Shingles because of their light weight become susceptible to wind load factors. High winds can uplift shingles and may require repairs to avoid leak penetration of rain and snow.
Not Environmentally Friendly:
Shingles are a petroleum-based product and are known not to be the most environmentally friendly. Their chemical components do not allow for recycling and eventually they will end up in a landfill somewhere.
