Asphalt Shingle Roofing
Asphalt shingles are by far the most popular choice for residential roofing because asphalt shingles are durable, versatile and economical. 4 out of 5 homes in Philadelphia, Pennsylvania suburbs, and the main line have asphalt shingles. In addition to being practical and affordable asphalt shingles comes in hundreds of colors, shapes, textures and architectural designs.
Benefits of Asphalt Shingles:
> Weather Resistant: Asphalt shingles perform well in extreme temperatures and in areas where wind, water, and ice are prevalent.
> Affordability: Asphalt shingles and installation are a fraction of the cost of other roofing materials.
> Low Maintenance: Asphalt shingles require little or no regular upkeep, and are easily repaired if damaged.
> Easy Install: Assuming your roofer knows what they are doing, asphalt shingles are the easiest roof to install.
> Fire and Wind Resistant: Asphalt shingles are manufactured to resist external fire and flammability standards, and carry Class A, B or C fire ratings, with Class A providing the greatest fire resistance. These fire ratings are defined by nationally recognized standards and tested by independent testing agencies. In addition, many asphalt shingles carrying a "wind resistance" label indicate that they have been manufactured and tested to demonstrate acceptable resistance in high-wind locations."
Asphalt Shingles Composition: Asphalt shingles are categorized as either organic-based or fiberglass-based. Organic-based asphalt shingles are manufactured with a base (also termed mat or substrate) made of various cellulose fibers, such as recycled waste paper and wood fibers. This organic base is then saturated with a specially formulated asphalt coating and surfaced with weather resistant mineral granules. Fiberglass-based asphalt shingles are manufactured with mat composed entirely of glass fibers of varying lengths and orientations. This fiberglass base is then surfaced with a specially-formulated asphalt coating, followed by weather-resistant mineral granules.
Asphalt shingles Types
Strip Shingles - these asphalt shingles are approximately three times as long as they are wide. Manufactured in both standard and metric dimensions, strip shingles are distinguished by the number of cutouts or tabs that they have. The most common type of strip shingle is the "three-tab" shingle. Different textural and lighting/shadowing effects can be achieved with strip shingles depending on the number, shape and alignment of the cutouts.
Laminated Shingles - these special shingles contain more than one layer of tabs to create extra thickness. They are also referred to as three-dimensional or architectural shingles because they create visual depth on a roof and impart a custom look. Laminated shingles continue to be a favorite among builders, roofing contractors and homebuyers.
Interlocking Shingles - as the name suggests, interlocking asphalt shingles are individual shingles that mechanically fasten to each other, and are used to provide greater wind resistance. They come in various shapes and sizes providing a wide range of design possibilities.
Large Format Shingles - generally rectangular or hexagonal in shape, these shingles do not utilize cutouts or tabs.
