GAF Roofing Systems: Flat Roof Repair Guide
Have a GAF roof or think you might? Learn what to check, which materials may be involved, and how to plan the next step when leaks or wear appear.
System overview
What GAF roofing may include
GAF is associated with tpo, pvc and asphalt-based systems. Different products call for different repair materials and methods. Before any work, confirm the exact roof system and check the original installation documents.
Heat, heavy rain and rooftop equipment can stress seams and flashing. The first job is to find where water enters, not simply cover the visible stain.
What deserves a closer look?
For this type of roof, focus on membrane seams, edge details and coating compatibility. A roof inspection should also consider drains, seams, flashing, previous patches and the condition of the roof below the surface.
How to plan a sensible repair
Find the cause
Look beyond the visible leak. Drainage, flashing and rooftop equipment can all affect where water travels.
Choose compatible work
Use methods that fit the product, roof condition and warranty terms. Ask for a clear scope before approving work.
What Houston weather can mean for this roof
Hot sun, sudden downpours and severe storms make routine checks valuable in the Alief area. After a storm, look for indoor stains or blocked drains, but leave roof access and repairs to trained professionals.
Repair or replacement?
A small isolated defect may be repairable. Widespread wet insulation, repeated leaks or major membrane wear may call for a larger plan. An inspection is the best way to compare options.

Questions about GAF roofing
What should I do if this roof starts leaking?
Protect the indoor area if it is safe to do so, note where water appears, and arrange a professional assessment. The source may be far from the stain.
Can I put a coating over this system?
Only if the coating is approved for the existing material and the roof is suitable. Trapped moisture or poor adhesion can cause problems.
Will a repair affect the manufacturer warranty?
It may. Review the warranty and ask the manufacturer or approved contractor before altering a covered system.
