For most homeowners looking to do a re-roofing job on a budget while maintaining a fairly attractive look and weather tightness of their home, a composition shingles roof aka asphalt is perhaps the most plausible, simple, and cost-effective solution.
In a highly competitive residential roofing market saturated with numerous options, asphalt shingles are by far one of the most popular choices.
While not as durable and long-lasting as some of the more premium roofing materials such as metal, cedar shakes, slate, or clay tiles, asphalt shingles can provide an adequate protection and sufficient aesthetic appeal at only a fraction of the cost of other systems.
In this guide you will learn about advantages and disadvantages of composition shingle roofs to help you decide if this popular roofing option is the best fit for your home.
Two Types of Asphalt Shingles:
Old School Organic shingles are based on paper (waste paper) saturated with asphalt to make it waterproof, with coatings of adhesive salt and ceramic granules embedded on top.
Fiberglass shingles are made with a base layer of glass fiber reinforcing mat. This mat is coated with asphalt, which contains mineral fillers and makes the shingle waterproof.
While organic shingles are more durable than fiberglass ones, they are more flammable and hence more prone to fire. They are less environmentally-friendly due to their high asphalt (oil based) content.
Fiberglass shingles offer excellent fire protection. Today, fiberglass shingles are more commonly used and are slowly, but surely, replacing the organic shingles.
