All Around Roofing: Honest Roofing Companies Denver
Asphalt shingles are a popular choice for residential roofing due to their flexibility, durability and cost effectiveness. Over the years, shingles are exposed to the elements, which can cause the components to break down. Denver roofing contractors are experts at assessing for signs of shingle damage and decay. By having the roof inspected at least twice a year, homeowners can take a proactive approach to roof maintenance and stop problems before they become major repairs. Understanding the different types of damage common to asphalt shingles will help homeowners make informed decisions about repair after each inspection.
Denting, or pitting, is one of the most common types of shingle damage. Homeowners will frequently attribute this phenomenon to defective materials. In truth, the damage comes from a much more direct source: hailstones. Hail stones are chunks of ice formed high up in the atmosphere that fall to earth at high speeds, usually during a thunderstorm. They can range in size from pea sized to as big as a grapefruit. It does not take large hailstones to cause damage to shingles, especially as the roof ages and loses its elasticity. Dents left by these stones can lead to shingles splitting, which allows water to penetrate to the underlayment below.
Wet underlayment can cause it to wrinkle as it expands and contracts during periods of moisture and dryness. These wrinkles will eventually become visible through the shingles, giving the roof a wavy appearance. When the shingles are not allowed to lie flat as they were intended, gaps can form between the individual shingles, allowing moisture to get between the layers.
Moisture trapped between the shingles, either during installation or due to an opening, can seep through the backing of the shingles and lead to bubbling. The presence of bubbling indicates that the shingles are losing their waterproof characteristics. The true extent and source of moisture damage must be evaluated before a contractor can recommend repair options.
One final type of damage common to asphalt shingles is alligatoring. This type of damage gets its name from the tiny lines that form on the surface of the shingle that resembles the hide of an alligator. It can be a normal part of the gradual decay of shingles or a sign of premature breakdown. Only professional roofing installers can tell the difference. If the cracks do not penetrate the shingle, it may not require immediate attention.
To keep shingles in the best condition possible, homeowners should keep an eye out for obvious signs of damage and contact a reputable roofing contractor as soon as they notice a potential problem.
