Rockland County Roofing: Article About Roofing Shingles
Residential Rockland County Roofing professionals spend a good portion of their time working with asphalt shingles. Most asphalt shingles have a warranty to last between 20 to 50 years. This warranty does not mean that the roof will last for 20 to 50 years; instead, the warranty is designed to only cover a fraction of the cost of the materials the older they get.
Some architectural shingles come with a "lifetime" warranty. This does not guarantee the product indefinitely. "Lifetime" is the name of the warranty, but the coverage is usually for between 10 and 15 years.
While there are many positives to using asphalt shingles, one negative is that they are not very energy efficient. They absorb a lot of heat from the sun and increase an attic's temperature. As consumers are becoming more concerned with energy efficient products, asphalt shingle manufacturers have designed Energy Star Label products to reduce the attic's temperature by as much as 20 percent during summer months. Solar reflective pigmentation is used to accomplish this. Even with this reflective material, the attic space will not completely cool down. Homeowners looking for an energy efficient roof may prefer to use metal roofing options.

Asphalt shingles have maintained their popularity because they can be installed on just about any type of roof, be it mansard, gabled or a hipped roof. They have also been installed on sheds, garages, and other buildings.
In most areas, building codes allow asphalt shingles to be reroofed, or placed over, existing shingles. Most building codes do not allow more than two layers of shingles. Homeowners should remember that if they choose this route, it is likely that they will lose their warranty.
Asphalt shingles provide excellent wind resistance. To obtain the maximum wind rating, it is recommended that six nails be used per shingle. Every shingle comes with a nail on line. If shingles are nailed to high or too low, they run the risk of being exposed to wind lift or water filtration.
While asphalt shingles are versatile, they are not designed to be installed on a roof that has a slope that is less than 18 degrees or 3:12. This is because asphalt shingles need gravity and slope to shed water. They should never be installed on flat roofs.
There are many factors that come in to play when choosing the right asphalt shingles for a home. It is recommended that homeowners take the time to review this material and speak to a contractor who can help them choose the right shingles for their home.
