Introduction
Repairing a tar and gravel roof is a practical DIY project, particularly for those who are comfortable working at heights. Unlike other roofing materials, tar and gravel roofs are relatively simple to fix, making them an appealing choice for seasoned DIYers. However, safety should be your top priority when working on any roof. This guide will walk you through the steps of repairing a tar and gravel roof, tips for staying safe, and when it might be best to call in professionals.
Understanding Tar and Gravel Roofs
Tar and gravel roofs, also known as built-up roofs (BUR), consist of multiple layers of materials such as asphalt, tar, or bitumen combined with a layer of gravel. This roofing system is commonly found on flat or low-sloped roofs and is praised for its durability and weather resistance.
Why Repair a Tar and Gravel Roof?
Over time, tar and gravel roofs may develop issues such as:
- Cracks or blisters in the surface
- Rusted or damaged flashing
- Accumulation of ponding water
- Granule loss after prolonged exposure to the elements
Addressing these issues promptly ensures that your roof remains watertight and prolongs its lifespan.

Before diving into your repair project, it’s crucial to prioritize safety. Here are several safety tips:
- Wear Protective Gear: Use gloves, sturdy boots, safety goggles, and a hard hat.
- Use a Secure Ladder: Ensure your ladder is stable and positioned on level ground.
- Work with a Partner: If possible, have someone nearby in case of emergencies.
- Be Cautious of Weather Conditions: Avoid working on your roof during rain, snow, or high winds.
- Inspect Your Equipment: Make sure all tools and equipment are in good working order.

Steps for Repairing a Tar and Gravel Roof
1. Assess the Damage
Before starting repairs, carefully inspect the roof for issues:
- Look for areas of damage or wear.
- Identify ponding water areas.
- Check flashing and edges for corrosion.
2. Prepare the Roof Surface
To effectively repair the roof:
- Clear the roof of any debris, leaves, or dirt.
- Trim back any overhanging trees that may damage the roof.
- Ideally, clean the area around the damage with a broom to ensure proper adherence of materials.
3. Repair Leaks and Punctures
-
For small leaks or holes:
- Use a putty knife to apply roofing asphalt around the damaged area.
- Press a patch or roofing fabric into the asphalt before covering it with more asphalt. This adds an extra layer of protection.
-
For larger damage or punctures:
- Cut a piece of fabric slightly larger than the damaged area.
- Apply roofing asphalt underneath and on top of the patch to seal it securely.
4. Fix Blisters or Cracks
-
Blisters can be a common issue with tar and gravel roofs:
- Use a utility knife to carefully cut open the blister.
- Allow moisture to escape, then fill the area with roofing asphalt.
- Smooth the asphalt out and apply a patch if needed.
5. Address Ponding Water
-
If you identify areas with ponding water:
- Increase drainage by adjusting the gravel — add more or redistribute it to create a slope.
- Consider adding drainage scuppers if necessary.
6. Check and Replace Flashing
-
Inspect the flashing surrounding chimneys, vents, and walls for any damage.
-
If rusted or damaged, replace it:
- Remove old flashing.
- Install new flashing, sealing edges with roofing asphalt.
7. Final Inspection and Sealant Application
After completing the repairs:
- Inspect your work to ensure everything is sealed correctly.
- Once satisfied, apply a sealant over repaired areas for added protection.
