The answer to 'how to maintain flat roof' is to regularly inspect, clean, and repair the roof to prevent leaks and extend its lifespan. This includes clearing debris, fixing cracks or holes, and applying sealants or coatings as needed. Proper maintenance of a flat roof is crucial to protect your home from water damage.
Inspect the roof at least twice a year, in the spring and fall, looking for signs of wear, cracking, or ponding water. Clear away any leaves, sticks, or other debris that could clog drains or cause damage. Seal any cracks or holes with a compatible sealant, and consider applying a reflective roof coating to protect the membrane from UV rays and extend its useful life.
