Avoiding Pitfalls: 7 Common Roofing Mistakes to Steer Clear Of

Silver Oak Roofing in Oakville, Ontario, provides insights on avoiding common roofing mistakes that can compromise the quality and longevity of your roof. Ensuring a flawless roofing job is crucial to protect your home from the elements and avoid costly repairs.

1. Choosing the Wrong Materials for Your Roof’s Slope

Importance of Matching Materials

Selecting the appropriate roofing materials for your roof’s slope is essential. For example, asphalt shingles require a slope of at least 4 units of rise per 12 units of run to function effectively. Using inappropriate materials can lead to water pooling and leaks.

2. Incorrect Nail Usage

Proper Nailing Techniques

Using too few nails or placing them incorrectly can significantly reduce your roof’s lifespan. Each shingle should have no fewer than four nails, and nails should be placed along the nailing strip for optimal security. Overdriven or underdriven nails can also cause issues, leading to gaps or damaged shingles.

3. Improper Valley Flashing Installation

Correct Flashing Placement

Valley flashing must be installed beneath the shingles to effectively divert water. Incorrect installation, such as placing flashing on top of shingles, can lead to leaks and water damage.

4. Ignoring Winter Climate Considerations

Preventing Ice Dams

In regions with harsh winters, proper underlayer installation is critical to prevent ice dams. Ice dams form when heat escapes from the attic, causing snow to melt and refreeze, which can lead to water seeping between shingles.

5. Over and Under Driven Nails

Precision in Nailing

Contractors in a hurry may overdrive or underdrive nails, compromising the roof’s integrity. Overdriven nails can damage shingles, while underdriven nails create gaps that allow water infiltration.

6. Re-using Flashings

Importance of New Flashings

Re-using old flashings can lead to vulnerabilities in your roof. New flashings provide better protection and ensure longevity, especially around critical areas like chimneys and walls.

7. Omitting Crickets Behind Chimneys

Diverting Water Away

A cricket, typically made of metal or shingles, is essential for diverting water away from the chimney. Omitting this component can lead to water accumulation and potential leaks.

Avoiding these common roofing mistakes ensures a durable, long-lasting roof that effectively protects your home. Proper material selection, nailing techniques, and installation practices are crucial to maintaining roof integrity and preventing future issues.
