Detailed Breakdown
Common Garage Roof Problems
Garage roofs often face issues like:
- Leaks: Water can seep through cracked or missing shingles or flashing, causing damage to the interior.
- Pooling Water: Flat garage roofs are more prone to pooling water, which can cause leaks or sagging over time.
- Damaged Shingles or Tiles: Exposure to harsh weather, like heavy rain or snow, can crack or loosen shingles.
- Sagging Roofs: A sagging garage roof can indicate a structural issue or weakened roof decking.
- Mold or Mildew: Persistent leaks or trapped moisture can lead to mold, which may spread to other parts of your home.
Materials You’ll Need
To tackle roof repair, you’ll need basic roofing materials like:
- Roofing cement or sealant
- Replacement shingles or tiles
- Flashing
- Roofing nails
- Tar paper or underlayment
- Ladder and safety gear
Depending on the extent of the damage, additional tools might include a hammer, pry bar, and caulk gun.
DIY Garage Roof Repair Tips
For small jobs, you can tackle garage roof repairs on your own. Here are a few DIY tips to get started:
- Fixing Leaks: Locate the leak and remove any damaged shingles. Apply roofing cement to seal small cracks or gaps, then place new shingles over the area. Ensure you nail them in securely and cover them with an additional layer of roofing cement.
- Replacing Flashing: Damaged flashing around vents or the edges of the roof can lead to leaks. Carefully pry up the shingles around the flashing, remove the old flashing, and replace it with new metal pieces. Secure the flashing with roofing nails and seal any gaps with roofing cement.
- Patching a Sagging Roof: If you notice a small sag in your garage roof, it might be due to weakened plywood decking beneath the shingles. To fix this, you’ll need to remove the roofing material, cut out the damaged section of decking, and replace it with new plywood.
- Cleaning the Roof: Regularly clean leaves, branches, and debris from your garage roof and gutters. This prevents water buildup and reduces the risk of leaks.
When to Call a Professional
While you can handle minor repairs, it’s crucial to know when to bring in the experts. If you notice any of the following, consider hiring a roofer:
- Extensive leaks or water damage inside your garage
- Structural damage, like severe sagging or rotting wood
- A need for a complete roof replacement due to age or weather damage
Professionals will assess the condition of your garage roof, recommend the best materials, and ensure a long-lasting fix.
Costs and Budgeting
The cost to repair a garage roof depends on several factors, such as the size of your garage, the materials used, and the extent of the damage. Here’s a rough breakdown:
- Minor repairs (patching small leaks or replacing a few shingles): $300 – $500
- Moderate repairs (flashing replacement or fixing larger leaks): $500 – $1,000
- Major repairs (significant water damage, sagging, or complete roof replacement): $1,000 – $1,500
