Clean off your roofs!
When rain falls in the Valley of the Sun, water is supposed to flow off as quickly as possible. One of the biggest causes of roof problems in the Phoenix Metro area (Scottsdale, Tempe, Mesa, Chandler, Gilbert, Glendale, etc..) is poor roof maintenance. Usually, a build-up of debris left on a roof by birds or trees in the culprit. These build-ups cause water to flow improperly (sideways and even backwards!) eventually causing roof leaks. Roof drains can be also be clogged or blocked.
