Frequently asked questions
How long does a roof seal last?
It depends on the system and on maintenance. The systems we install carry a written warranty, and the exact term goes in your contract.
How long does the job take?
An average residential roof takes 2 to 4 days, including washing, repairs and membrane coats.
Can you seal during the rainy season?
Yes, with planning. We schedule application on dry days and each coat gets its curing time.
Do you repair just the leak, or does the whole roof need sealing?
We inspect first. If the rest of the roof is in good shape, we repair the area. If the sealant is past its life, sealing the whole roof is the better choice, and we tell you so in the estimate.
