Identifying Common Garage Roof Problems

Before you can fix a problem, you need to know what you’re dealing with. Here’s a rundown of typical issues you might encounter:

  1. Leaks and Moisture: The most common sign that repairs are needed. If you spot water stains or drips, it’s time to investigate.
  2. Sagging and Structural Damage: Sagging can indicate serious issues like rot or structural overload.
  3. Worn or Missing Shingles: Exposed or missing shingles leave your roof vulnerable to the elements.
  4. Pooled Water: A flat roof with poor drainage can lead to water pooling, which increases the risk of leaks.

Choosing the Right Materials for the Job

Selecting the proper materials is crucial for effective repairs. Here’s what you’ll need to consider:

  • Roofing Shingles or Panels: Match the existing material to maintain uniformity and integrity.
  • Underlayment and Flashing: Essential for waterproofing and preventing leaks.
  • Sealants and Caulks: Choose high-quality options to ensure a durable seal.

Give your roof a thorough inspection. Identify all problem areas before beginning any work to ensure nothing is overlooked.
