Roofing manufacturers have asphalt shingles for specific climates. If you get the wrong shingles, your roof might not last as long as a neighbor who used the right products. Below are some of the shingles that manufacturers have formulated for specific areas.
Impact Resistant Shingles
According to the Insurance Information Institute (III), hail damage causes over a billion dollars' worth of property and crop damage every year. Hail can strip the protective granules off the shingles, crack the shingles, and even displace the shingles from their positions.
Roofing manufacturers have come up with impact-resistant shingles to reduce the risk of hail damage. According to nachi.org, shingles come with impact-resistant ratings from 1 to 4, with class 4 shingles having the highest impact resistance. Consider the rating if your area experiences a lot of hailstorms every season.
Get cool shingles if your area experiences considerable sunlight and temperatures most of the year. Sunlight can cause shingle damage by:
- Drying the shingles so that they lose their flexibility and become susceptible to cracking
- Heating the roof surface and accelerating the degradation of roofing materials
- Heating the attic and increasing energy consumption for air conditioners
Cool shingles reduce the risk of heat/sunlight damage by reflecting most of the sunlight incident on the roof surface. The cool roofs come with reflective granules or lighter colors that minimize the amount of heat that penetrates and heats the shingles.
Stain Resistant Shingles
Two things make algae bad for your roof. First, algae stain the roof and lower your home's curb appeal. Secondly, algae retains moisture and keep your roof wet most of the time. Constant moisture on the roof can lead to corrosion, rot, and water leakage.
Algae-resistant shingles reduce the risk of algae growth on the roof. The shingles feature copper granules, which are effective because copper kills algae. Get these shingles if you live in a wet climate, and roofs in your area are prone to shingle growth.
Wind Resistant Shingles
Lastly, you should install wind-resistant shingles if windstorms are common in your area. Strong winds can rip shingles off your roof, damage individual shingles, or even uplift the whole roof.
Wind resistance standards determine the wind speeds that roofing materials can withstand. For example, class D shingles can withstand winds up to 90 mph while class H shingles can withstand winds up to 150 mph. Your roofing contractor can help you determine which level of wind-resistance is appropriate for your area.
