When it comes time to choosing a new roof, some key considerations are the type of material, style, color and of course, cost. There are several different types of roofing materials available now, including many that have a variety of green attributes, such as being ENERGY STAR rated or containing recycled content.
Not every roofing material can be used on every roof. A flat roof or one with a low slope may demand a surface different from one with a steeper pitch. Materials like slate and tile are very heavy, so the structure of many buildings is inadequate to carry the load. Consider the following options, then talk with Lake Champlain Roofing and request an estimate for your job needs.
This is the most popular single-ply roofing system.
EPDM is essentially a rubber membrane roofing system that is applied to flat/low sloped roof areas. Generally it is done on commercial buildings, but can also be installed residentially on low sloped roof areas such as porches. There are 15, 20 or 30 year material warranty (commercial applications only) on the product itself. It is a great material for re-roofing jobs because of its lightweight construction material.
This is the most commonly used of all roof materials, and is made of a fiberglass medium that’s been impregnated with asphalt and then given a surface of sand-like granules. Two basic configurations are sold: the standard single-thickness variety and thicker, laminated products (architectural). The costs of both run about the same due to how they are installed, but laminated shingles have an appealing textured appearance and last roughly 50 years (lifetime warranty). Prices vary depending upon the type of shingle chosen and the installation.
Aluminum, steel, copper and lead are all durable—and expensive—roofing surfaces. Lead and copper varieties are typically installed as shingles, but others are manufactured for seamed roofs consisting of vertical lengths of metal that are joined with solder. These often cost two or three times that of shingle roofs, but carry an 80 plus year warranty.
Slate is among the most durable of all roofing materials. Not all slate is the same—some comes from quarries in Vermont, some from Pennsylvania and other states—but the best of it will outlast the fasteners that hold it in place. Hundred-year-old slate, in fact, is often recycled for reinstallation, with the expectation it will last another century. But slate is expensive and very heavy. With proper yearly maintenance, it will outlast most other roofing products.
Standing Seam metal roofing is becoming more popular and though metal roofing prices are often three times higher than the costs of conventional asphalt roofs, some consumers find them the preferred alternative.
Mostly cut from cedar, wood shakes and shingles also have their place in the roofing industry. Wooden shingles will provide a crisper look with finer lines and are squarer in shape. Wooden shakes have a more rugged look being hand split and thicker. Both can be treated with a fire retardant or pressure treated to help with longevity and fire ratings.
The half cylinders of tile roofing are common on Spanish Colonial and Mission styles; cement and some metal roofs imitate tile’s wavy effect. All are expensive, very durable, and tend to be very heavy.
