Albany Roofers: Article About Roofing Technology
When a house needs to have its roof replaced, property owners are faced with many decisions about which materials to use. Asphalt shingles continue to be a popular choice in northern New York, as they are affordable, durable and easy to install. Shingle manufacturers have improved their manufacturing processes and materials to create stronger and more weather resistant products that are guaranteed to last a lifetime. Homeowners interested in these innovative products can work with Albany roofers to determine which roofing materials are best suited to their homes.
Three layered lamination is a new process in which manufacturers build up a shingle using a layer of fiberglass, coated with asphalt and granules, covering this in more asphalt, and repeating this with two more layers of the same materials. The finished product is thick, heavy and waterproof, which is just what a home needs when it is located in a place that gets heavy snow and has long, cold winters. The completed shingles measure more than five eighths of an inch thick, which is about 30 to 50 percent thicker than dimensional shingles and twice as thick as basic 3 tab shingles.
The three layered shingles have a 4 inch exposure with staggered edges. The edges and top layer are created to mimic the look of cedar or redwood shakes.

However, wooden shakes only last for about 25 years and require a great deal of maintenance in order to retain their beauty and strength. These specialty shingles do not require any annual sealing or extra care.
Also built into these shingles is a newer way to prevent unsightly rooftop algae stains. These dark streaks are an eyesore and make the roofing system look older than it really is. The granules on the outer surface of the shingles have embedded bits of zinc, which prevents the algae from growing or starting new colonies. The algae free guarantee of these shingles is typically 10 to 15 years.
Weather resistance is also of importance to homeowners. Winds and impacts from hailstones or fallen tree limbs can wreak havoc on a roof. Manufacturers are adding an extra layer of plain fiberglass to the backs of some shingles. This prevents the shingles from cracking when an impact occurs. This can help to protect the roof during a storm. These shingles can withstand winds of 130 miles per hour.
To keep roofs cooler during the summer, manufacturers are using ceramics. Granules sprayed with a white ceramic glaze resist heating and withstand the sun's ultraviolet rays for a longer time.
