Understanding Tar Roofs

Tar roofs, often found on commercial buildings and flat-roof residences, are popular for their durability and water resistance. Over time, however, even the best-maintained tar roofs can develop leaks or damage due to weather conditions, wear and tear, or improper installation. Repairing a tar roof can be a straightforward process if you follow the proper steps.

Types of Tar Roofs

1. Built-Up Roofs (BUR): These consist of multiple layers of bitumen and reinforcing fabrics, providing a strong and durable surface.
2. Modified Bitumen: This type is similar to BUR but comes with a few improvements, such as the use of polymer-based materials.

Understanding the type of tar roof you have will help you effectively tackle repairs.

Tools and Materials Needed

Before starting the repair process, ensure you have the following tools and materials:

Tools:

• Safety Gear: Gloves, goggles, and a hard hat.
• Roofing Knife: For cutting out damaged sections.
• Spatula or Trowel: For applying patch material.
• Ladder: To access the roof safely.
• Pressure Washer: For cleaning the surface.

Materials:

• Roofing Tar: The main product for sealing.
• Roofing Fabric: For reinforcing patches.
• Gravel or Aggregate: To cover repairs and protect them from UV rays.
• Sealant: For additional waterproofing.

Step-by-Step Guide to Repairing a Tar Roof

Step 1: Inspect the Roof

Start with a thorough inspection. Look for visible signs of damage such as:

• Blisters or bubbles in the surface.
• Cracks or seams that have opened.
• Punctures from debris.
• Areas with pooling water.

Take note of all damaged areas to address them effectively.

Step 2: Clean the Roof Surface

A clean surface is essential for a successful repair. Follow these steps:

• Use a pressure washer to remove dirt, debris, and any loose materials.
• Allow the roof to dry completely before proceeding. Moisture can affect the adhesion of the new tar.

Step 3: Cut Out Damaged Areas

For blisters or cracks:

1. Use a roofing knife to cut out the damaged area.
2. Make a square or rectangular cut around the damaged section for a clean removal.
3. Remove the cut-out section and any underlying debris to expose the roofing felt.

Step 4: Apply New Material

For Small Repairs:

• For minor cracks, apply roofing tar directly over the damaged area using a trowel or spatula.
• Ensure an even coat and feather out the edges to blend with the surrounding roof.

For Larger Repairs:

1. Cut a piece of roofing fabric slightly larger than the removed section.
2. Apply a layer of roofing tar to the exposed surface.
3. Press the fabric into the tar, ensuring it adheres well.
4. Apply a second layer of tar over the fabric, ensuring it is thoroughly covered.

Step 5: Protect the Repair

• Cover the new material with gravel or aggregate. This protects the repair from UV rays and adds weight to keep it from lifting.
• Ensure the aggregate is evenly distributed over the new patch.

Step 6: Final Inspection

• Once dry, perform a final inspection to ensure no areas are missed.
• Check for any remaining cracks or issues.

Maintenance Tips for Tar Roofs

To extend the life of your tar roof, follow these maintenance tips:

• Regular Inspections: Check your roof at least twice a year, especially after severe weather.
• Keep it Clean: Remove debris and leaves that can trap moisture against the surface.
• Prompt Repairs: Address any signs of damage immediately to prevent larger issues.
• Use UV Protection: Consider applying a UV protective coating every few years to minimize wear on your tar surface.
