Asphalt shingle roofing is best known for its affordability, durability and aesthetic appeal. However, like all roofing materials, asphalt shingles can encounter some issues over time. One such problem is blow-offs. Roofing and home renovations expert Ben’s Construction Inc. explores the culprits behind asphalt shingle blow-offs and ways to address and prevent them.
Asphalt shingle blow-off is a prevalent roofing issue where the shingles, the protective outer layer of a roof, are dislodged and carried away by wind. The term can describe when an entire shingle is removed or only parts, like corners, are torn off, leading to leaks.
This problem is usually a result of severe weather conditions or improper installation, which cause shingles to break loose from their sealant bond. If untreated, blow-offs can cause serious damage, such as leaks, structural impairments, or mold growth, emphasizing the critical need to address the issue promptly.
Understanding the causes of asphalt shingle blow-off is essential for homeowners to take preventive measures and maintain a sturdy roofing system. Let’s explore the primary factors contributing to shingle displacement and how they can adversely affect your home.
Improper installation is the most common reason behind shingle blow-off. If shingles are not appropriately fastened or installed during cold weather, the adhesive strip might not stick well, making them susceptible to blow-off.
Roofs are constantly exposed to various weather conditions, and strong winds in particular can be harmful. If a house is located in an area frequently subjected to high winds, there’s a higher chance that the shingles might dislodge and blow off.
As with any material, shingles deteriorate with age. An old shingle can lose its flexibility and adhesive power, becoming prone to wind damage.
Lack of proper ventilation can also accelerate the aging process of shingles. In such circumstances, the trapped heat and moisture can speed up the deterioration, eventually leading to blow-offs.
Asphalt shingle blow-off can lead to several immediate and long-term consequences for a home, some of which can be costly and potentially dangerous. The following are some common effects:
When shingles are dislodged, the roof becomes vulnerable to water intrusion. Water can seep through the exposed areas, leading to leaks inside the house, which may eventually cause damage to the attic, ceilings, walls and insulation.
Moisture from water intrusion due to blow-off can create an ideal environment for mold and mildew growth. These health hazards can cause respiratory issues, allergic reactions, and various illnesses, putting the well-being of the inhabitants at risk.
As water penetrates the exposed areas, it can reach the underlying roofing system, causing the wood’s fibers to weaken and ultimately lose their ability to support the roof’s weight. Rotted decking and structural damage can pose a significant safety threat and require costly repairs or even a full replacement.
Shingle blow-off can compromise the insulation capacity of your roof, leading to a less energy-efficient home. Consequently, heat escapes during winter and cold air escapes in summer, resulting in higher energy consumption and utility bills.
Besides the practical implications, the visual appeal of a home can be significantly affected by missing or damaged shingles. Blow-offs can leave unsightly gaps on the roof, reducing the property’s curb appeal and potentially affecting its market value.
Addressing blow-offs immediately is crucial to prevent further damage. The fixes involve either repair or replacement, depending on the condition of the shingles and the extent of the damage.
Replacement is the most viable solution if the shingles are severely damaged or missing. Remember to choose a good-quality and wind-resistant shingle for areas prone to high winds. Ensure professional installation to minimize the chances of future blow-offs.
For shingles that are not severely damaged but have come loose, resecuring them can help. This might involve reaffixing the shingle using roofing nails and applying a good-quality roof sealant to ensure they’re tightly held.
Enhancing attic ventilation can aid in reducing trapped heat and moisture, extending the lifespan of shingles and reducing the risk of blow-off. Make sure an experienced professional roofing contractor performs this job for an effective roof ventilation system.
Whether to repair or replace your roof due to lifting and blow-off issues depends on the factors below.
Minor damage, like a few loose or missing shingles, can be remedied through repairs. Conversely, a replacement might be more cost-effective if a large portion of the roof is affected.
Consider the age of your roof. Roof replacement is likely a better investment if it is experiencing frequent problems. You also need a new roof if your current one is nearing or has exceeded its suggested lifespan, which is approximately 20 to 25 years for asphalt shingles.
If you plan to live in your current home for many more years, investing in roof replacement might be more beneficial in the long run. However, repairing the existing roof may suffice if you will be moving soon.
To avoid financial issues, you should always consider the cost of installing a new roof. While roof replacement can be a significant initial investment, it might save money in the long run due to less required maintenance.
