Like your automobile, a roof benefits from regular maintenance.
Your car needs tires, brakes, wiper blades, oil, etc. However, they wear out in time and need to be replaced. You wouldn’t throw away your car because items wear out, you have them repaired or replaced and the car performs well until they wear out and the repair process is repeated. A roofing system functions the same way. Seams open, fastners back out, flashings deteriorate, drains need cleaning, in addition to many other repairable roofing issues.
Your roof is an investment, and like your car, regular maintenance is necessary to obtain its optimal lifetime usage. With periodic maintenance, your roof will perform as it was intended, as well as extending the life of the roofing system.
