Drywall is a fundamental building material found in most homes and commercial spaces. While it offers a smooth, paintable surface, it's also susceptible to water damage. Water damage to drywall can lead to structural issues, mold growth, and costly repairs. As the experts in drywall repair, PatchMaster Serving North York & Surrounding Areas is here to shed light on the top 5 common causes of water damage to drywall and provide insights on how to address them.

A leaking roof is one of the leading culprits of water damage to drywall. Roof leaks can occur because of damaged shingles, deteriorated flashing, or improper installation.

How to Address It:

  • Regularly inspect your roof for damaged shingles or flashing.
  • Promptly fix any leaks or consider roof replacement if necessary.
  • Repair or replace affected drywall sections and repaint.

How to Address It:

  • Regularly inspect plumbing fixtures and pipes for leaks or corrosion.
  • Repair or replace damaged pipes immediately.
