Flat Roof Repair by Roof Type

Identifying the roof covering helps narrow down likely defects and the preparation required before any repair. Use the material-specific SealForge guides below.

GRP fibreglass flat roofs

GRP roofs can develop local cracks or defects around details. Start with GRP Fibreglass Roof Cracks and Leaks and the Flat Roof Crack Repair Guide.

EPDM rubber flat roofs

Investigate seams, edges, details, penetrations and previous repairs. See EPDM Rubber Roof Leaks: What to Check and Flat Roof Joint or Seam Leaking.

Felt flat roofs

Check for splits, laps, blisters, edges and wider deterioration. See Felt Flat Roof Leaking, Flat Roof Split Repair and Flat Roof Blisters and Bubbles.

Not sure what roof covering you have?

Start with the Flat Roof Leak Help Centre and diagnose the defect before selecting a repair approach.

Local repair or larger work?

Use the Flat Roof Repair or Replacement Decision Guide. If the defect is localised and the surrounding roof is sound, learn about reinforced local repair.

For an appropriate localised defect, view the SealForge Reinforced Flat Roof Repair Kit.
