Care for a low-slope or membrane roof
Low-slope roofs depend on intact seams, flashings and open drains. Small punctures or persistent ponding can become concealed leaks.
Recommended timingTwice a year and after severe weather
What to do
- Use safe ground- or window-level views to look for debris, displaced edge metal, obvious membrane damage and water that remains well after a storm.
- Have a qualified roofer inspect drains, scuppers, seams, penetrations, flashings and the membrane at least twice yearly and after major wind, hail or rooftop work.
- Keep contractors from placing sharp tools, equipment or unprotected traffic on the membrane, and document every rooftop visit or repair.
- Use only repair materials and methods approved for the exact membrane system; incompatible coatings, solvents or sealants can damage it.
- Investigate interior staining promptly even when the roof entry point is not directly above it.
Do not walk a low-slope roof merely because it appears flat. Falls, hidden weak areas and membrane damage are serious risks; use a qualified roofer.
