Asphalt shingles are a popular roofing choice due to their affordability and ease of installation. However, they are prone to blowing off during strong winds, causing homeowners significant frustration. Silver Oak Roofing, located in Oakville, Ontario, explains why this occurs and offers tips to prevent it.



Reasons Why Asphalt Shingles Blow Off


Lack of Adhesion


The lightweight design of asphalt shingles can make them susceptible to strong winds if not properly adhered. Over time, the adhesive that holds them in place can weaken, especially if the shingles are old or have been improperly installed.


Age and Condition


As shingles age, their ability to withstand wind diminishes. Older shingles are more likely to blow off, particularly during high winds, due to decreased adhesion and overall wear.


Installation Quality


Improper installation can significantly increase the risk of shingle blow-off. Ensuring shingles are correctly aligned, securely nailed, and adhered is crucial for their stability.


Preventing Asphalt Shingle Blow-Off


Proper Maintenance


Regular maintenance is essential for keeping shingles in place. This includes cleaning the roof to remove debris and repairing any damaged areas to maximize shingle adhesion.


Professional Installation


Hiring a professional roofer ensures that shingles are installed correctly and can withstand high winds. Professionals use appropriate techniques and materials that comply with local building codes, enhancing the roof's durability.


Additional Measures


  • Roof Caps and Anchors: Installing roof caps and using roof anchors can provide additional security for shingles during high winds.

  • Roof Rakes: Using a roof rake can help manage snow and ice buildup, reducing the risk of shingle blow-off in winter.


Proper Installation and Maintenance Tips


Installation Tips


  • Use Quality Shingles: Purchase shingles designed to withstand the wind conditions in your area.

  • Align and Secure Shingles: Ensure shingles are properly aligned and secured with nails or staples.

  • Prepare the Roof: Clean the roof and install proper underlayment before laying shingles.


Maintenance Tips


  • Annual Cleaning: Clean the roof at least once a year to remove debris that could affect shingle adhesion.

  • Regular Inspections: Have the roof inspected regularly to catch and address potential issues early.

  • Ensure Proper Drainage: Maintain gutters and downspouts to prevent water accumulation, which can weaken shingles.


Advantages of Asphalt Shingles


  • Cost-Effective: Asphalt shingles are relatively inexpensive compared to other roofing materials.

  • Durability: With proper installation and maintenance, asphalt shingles last up for 30 years.

  • Variety: Available in various styles, colors, and textures to suit different aesthetic preferences.


Alternatives to Asphalt Shingles


  • Metal Shingles: Durable and designed to withstand high winds, hail, and heavy rain, but more expensive.

  • Wood Shingles: Another durable option, offering a unique aesthetic, though less common.

  • Composite Shingles: Provide durability and a variety of design options.


Frequent blow-off of asphalt shingles can be mitigated through proper installation and regular maintenance. Hiring professional roofers and taking additional measures like installing roof caps can enhance the durability and stability of your roof against high winds.
