Built-Up Tar-and-Gravel Roofs: Care and Next Steps
Built-up roofs stack layers of felt and asphalt, often topped with gravel. Many older Dallas buildings still have them.
Signs of aging
Exposed felts, bare spots in gravel, blisters, and cracked flashing are common clues.
Repairs
Repairs often use compatible asphalt products. Gravel must be cleared for a proper patch.
Next steps
Old BUR may contain multiple layers, which affects recover options. A survey helps decide.
Common questions
- Is the gravel needed?
- It protects the asphalt from sun.
- Can I add a single-ply over it?
- Sometimes, with the right preparation and codes.
