Atlanta Roofing-What Are The Pros And Cons To Using Composition Shingles On My Roof?
When it comes to replacing the roof, many homeowners want something that is inexpensive and will last a long time. For that reason, composition shingles are the most common roofing material used by Atlanta roofing contractors. They are one of the most economical choices, are fairly easy to install, and can last up to ten or more years before they need to be replaced.
Composition shingles come in a variety of colors, patterns and materials. Lighter colored shingles are popular because during summer months, they reflect more sunlight. That helps to keep the attic cooler and the energy bills lower.
This type of shingle can be made of asphalt, fiber glass or even recycled materials.
The shingles are not complicated to install, so roofers can finish the project in less time.
A good thing about composition shingles is you can walk over them without worrying about breaking them. That makes regular inspections easier. They are flexible and have a good fire retardant rating. Granules imbedded in the shingle help reflect harmful UV rays. Also, repairing and replacing just a few damaged shingles is a fairly easy task, especially for a trained Atlanta roofing contractor.
Because of their versatility, composition shingles can be applied to many styles of roof architecture and pitch. However, they can be a bit “plain Jane”. They are the type most commonly used in tract housing. If you have a custom built European cottage style home, and antebellum home or a perhaps a Mediterranean/Southwestern style, composition shingles may not give you the right look.
For a bit more, you can purchase what is called “architectural” shingles instead of the average flat shingle. Also called shadow shingles, these can appear more three dimensional and mimic the look of wooden shakes. Expect to pay a bit more for this style of composition shingle.
Your Atlanta roofing contractor can show you examples.
An Atlanta roofing expert will tell you another downside to composition shingles is they do not last as long as other roofing materials, such as metal or tile. Metal and tile can last four or five times longer, depending on weather conditions. But, composition shingles are lighter weight and more flexible, so often times no reinforcing is needed as can be the case for tile. However, that also means these types of shingles have a tendency to blow apart in high winds. They also may get scarred or curl if exposed to extreme temperatures.
Composition shingles are susceptible to algae build-up or moss if moisture gets in between them. They can separate or decompose, which shortens their ability to provide protection for your home and belongings from the elements.
In the past, many homeowners have tried to lay replacement shingles over the older ones.
However, most professional Atlanta roofing experts discourage this.
In fact, in more and more areas of the country, building codes prohibit this. This is because simply covering up the problem may not solve it and actually lead to worse leakage. It also is easy to spot a house that has layered shingling. Often times, the older asphalt shingles buckle up underneath, leaving the roof looking lumpy.
You have to weigh the odds. If you want a fairly inexpensive, easy to install and less labor intensive roofing material, composition shingles are a good option. Just remember, they may not be as durable as pricier choices.
