Maintenance Tips

Clean the Surface & Maintain Gutters
Clear the roof surface and drainage systems of debris. This includes leaves, branches, and dirt. These can cause water to pool and lead to damage over time.

Regular Inspections
Schedule regular roof inspections, particularly after extreme weather conditions, to identify any early signs of wear or damage.

Reapply Protective Coatings
For liquid-applied systems, you may need to reapply protective coatings from time to time. This helps extend the life of the roof and keeps it waterproof.
