How to Reseal a Lanai Roof
Lanai roofs put up with as much weathering and abuse as a regular home roof. But, because lanais are exterior, non-essential structures, their maintenance is often put off until there is a problem like a leak. Re-sealing the lanai roof will patch up minor flaws and stop leaks. For the best results, have a professional inspect the roof before you reseal. The roof may have bigger problems that a seal coat won't fix.
Clean the roof surface with a long-handle scrub brush and soapy water. Rinse the soapy residue away with a hose. Towel off any puddled water. While you're on the roof, examine its condition. Nail down or replace any lifted or rusted flashing, rusted sections of metal, or missing roof tiles. Roof sealant is meant to seal small fissures and pores, not large holes or rusted out areas. Wait until the roof is repaired and dry before moving on to the next step.
Apply one even coat of the sealant to the roof with a spray painter, long-handle paint roller or paint brush. Follow the sealant's instructions for application methods and amounts. Let the first coat dry for the manufacturer-recommended amount of time. Most sealants dry to the touch in 20 minutes to 1 hour, or sooner during warm weather.
Apply two to three more coats of sealant. Allow each coat to dry before applying the next.
- Reseal the roof during mild weather. The sealant's curing time is dependent on the temperature. At temperatures below 50 degrees Fahrenheit, the sealant may not cure properly. If temperatures climb above 80 degrees Fahrenheit, the sealant may dry quicker than you can apply it.
