why is my asphalt shingles curling shingles

Roofing

The answer to 'why is my asphalt shingles curling shingles' is that asphalt shingles can start to curl for several common reasons, including improper installation, aging, and exposure to the elements. Curling is a sign that the shingles are deteriorating and no longer providing adequate protection for your roof.

Some of the most common causes of asphalt shingle curling include: poor attic ventilation, excessive heat buildup, damage from UV exposure, and improper installation or nailing. Over time, the shingles can start to warp, buckle, and curl up at the edges, leaving your roof vulnerable to leaks and further damage.

Step-by-Step Guide

  1. 1

    Inspect the roof

    Closely examine the shingles to identify the extent and causes of the curling. Look for signs of damage, poor ventilation, or other underlying issues.

  2. 2

    Re-secure loose shingles

    If the curling is minor, you can try to re-secure the shingles using roof cement or sealant. Apply a generous amount under the curled edges and press the shingles back down firmly.

  3. 3

    Improve attic ventilation

    Inadequate attic ventilation can contribute to shingle curling. Consider adding more vents or improving airflow to help regulate temperature and moisture levels in the attic.

  4. 4

    Replace severely damaged shingles

    If the shingles are cracked, torn, or missing, you'll need to replace them. This is best done by a professional roofer to ensure proper installation and prevent further issues.

Frequently Asked Questions

When should I call a professional for curling shingles?

If the curling is widespread or the shingles are cracked, torn, or missing, it's best to call a professional roofing contractor to inspect and repair the roof. Attempting DIY repairs on an extensively damaged roof can be unsafe and may not address the underlying issues.

Can I fix curling shingles myself?

For minor curling or lifting of shingles, you may be able to fix the problem yourself by re-securing the shingles with roof cement or sealant. However, if the curling is severe or caused by deeper issues like poor ventilation, it's best to have a professional roofer assess and repair the roof.
