From distinguished architectural laminates down to basic three-tabbed shingles, asphalt roof shingles remain the most common roofing material in North America.
Offered in many grades, styles and colors, there are asphalt shingle products suitable for any application or budget. Quality and durability of individual products varies substantially and construction of individual products determines life expectancy.
Why choose Asphalt Shingles?
Choose asphalt shingle products for an easily installed, commonly-available, economical and durable roofing solution for any estate, heritage, commercial building or suburban home. Individual product life expectancy may range from 15 to 40 years, and pro-rated warranties offered may be limited to materials replacement.
Architectural asphalt shingles can offer the upscale dimensioned look of upscale cedar, slate, or tile roofing.
Asphalt Shingle Durability
Performance of asphalt shingles varies with the style, construction and material used in their manufaActure. Fiberglass or organic mats incorporated with asphalt, and granular materials and laminated result in a stronger product with more resistance to tearing, sun damage, curling and cracking with age. Some heavier, interlocking designs offer superior resistance to wind damage. Life expectancy is considered to be 20 to 30 years for an average product, with the higher-end laminated shingles life expectancy being 40 years.
Asphalt Shingle Installation
Installation of asphalt shingles is a process requiring moderate skills. Shingles may be installed on clean, even roof deck using roofing nails. An underlayment of building paper or roofing felt may be installed. A drip edge and a 36″ strip of an ice and water product should be installed along drip edges to prevent water backup and damage from ice dams. Shingles may also be installed over one layer of old shingles.
Ideal Applications for Asphalt Shingles
Asphalt shingles are the universal roofing solution for any roof but flat. A roof pitch under 3:12 requires a roof membrane be installed. In any climate except the most extreme, shingles can be a suitable roofing product.
Fire Rating of Asphalt Shingles
Asphalt shingles are rated as Class A, B, or C depending upon the specific product. Asphalt is combustible, but heavy applications of granular materials provide fire resistance.
Standards for hail damage are not universally available for all brands. Class 4 is the highest rating. Underwriter’s Laboratory UL 2218 does not require mandatory reporting.
Tear and wind resistance on some products are rated by a common standard with no mandatory reporting requirement.
Moss and Algae:
Some shingle products may have metallic compounds added to resist moss and algae growths.
Asphalt shingles range substantially in price from economy 15-year shingles to the distinguished architectural interlocking designs. They are less expensive than metallic shingles, but more expensive than roll roofing.
Asphalt roofing is lighter than slate or ceramic tiles, but heavier than cedar roofing and many metal roofing products. Laminated shingles tend to be heavier with more layers added. An average shingle product weighs about 235 lbs per square (10ft.x10ft.) and laminated shingles weigh much more.
Some architectural asphalt shingle products may last 45 years or even longer, but most shingles show signs of failure after 20-25 years. Rating must also vary anywhere from 3 to 7 depending upon the quality of the product chosen.
Asphalt shingles are offered in tab-free and unique interlocking designs as well as the traditional three-tabbed design. Many colors are available creating excellent choice for the potential roofing customer.
Asphalt shingles may be recycled into new roofing products.
Choose asphalt shingles for anything from an ordinary, economical re-roofing job to an upscale heritage roofing solution.
