As an Atlanta homeowner you do not need to know everything about your roof (unless you are planning to become a professional roofing contractor) but it would be good to know a thing or two about your roof so when the time comes to get your roof repaired or replaced, you can make an informed decision about what needs to be performed.
There are many types of roofing systems, but what is commonly used for residential houses is the steep-slope system or a roof that has an incline of 25 percent or more and has a more severe pitch when compared to other roofing types or systems. The steep-slope roofing system has five primary components:
Roof covering or the outer and top most layer of the roof, examples are tile, shingles, slate or metal.
Sheathing is flat boards or panels that support the roofing shingles. Sheathing is fastened to roof rafters to cover a house or building.
Roof structure is the top most part of a house or building that supports the roof. It keeps the shingles in place and is the strength that anchors the entire roof together.
Flashing is the material that is connected to the joints, valleys or other weak points of the roof structure to prevent water seepage.
Drainage is the special feature of the roof that allows water to drain off the roof.
Primary Type of Roof Covering
According to Roofcoonline.com, asphalt shingles reinforced with organic and fiberglass materials are the most widely used roofing material in the United States especially for a steep-slope roofing system. It is cost effective, durable and can provide great aesthetic and architectural style to the house. Furthermore, asphalt shingles are fire-resistant and are available in many colors, sizes and designs.
Wood shingles and shakes are manufactured from natural wood like cedar and redwood. Its rustically unique appeal and durability makes it popular in Northwest and parts of the Midwest. On the other hand, although it is very appealing, you have to consider that wood shingles and shakes have Class C fire rating or none at all, meaning it is not very resistant to fire unlike other roofing materials.
Tiles are fabricated using clay or concrete making it a very durable roofing material. It is available in differing hues and finishes and is used mostly in the Southwest and Florida. Because of its composition, tiles are fairly heavy so you must be sure that your house structure can carry the weight of tiles or it might cave in.
Slates are natural stones quarried in New York, Vermont, Virginia and Pennsylvania, and generally known as having the highest quality and longest lasting roofing materials in the market. However, because of its difficulty in installation that requires a professional slater, it comes with a relatively high cost and the fragility slate roofing is not ideal for everyone.
Metal shingles and roof plates were commonly used for low-slope roofs but are also now available for steep-slope roofs. This type of roofing material is durable, light-weight, and has high fire resistance. It also has great resistance to adverse weather conditions such as wind and hail.
How do You Make Your Atlanta Roof Last Longer
You can make your roof last longer by providing proper ventilation as it prevents heat and moisture from building up inside your roof; improper or insufficient ventilation may cause heat and moisture build up that may lead to buckling, rot, moss and other enemies of your roof that may cause damage and make its lifespan shorter.
