The type of roofing materials used, as well as your roof’s age, will usually determine how frequently roof maintenance should be performed.
It is recommended by the National Association of Home Builders to get roof inspections every 3 years for proper maintenance to check for damage or wear, though Zillow recommends obtaining a yearly inspection to be on the safe side. We advise you should seek out roof maintenance services whenever you notice signs of wear or damage (particularly after a severe storm).
