A monsoon is caused by warm air creating surface low pressure zones that in turn draw moist air from the oceans. Arizona winds usually come from the west, but shift to a southeasterly wind in the summer, bringing moisture, most often from the gulfs of Mexico and California. The wind shift and increase in moisture combine with the surface low pressure from the desert heat to produce storms in a cycle of “bursts” (heavy rainfall) and “breaks” (reduced rainfall). Before the rain, the wind shift can trigger dust storms known as  haboobs, which appear as loose swirling walls of dust several hundred feet high.

What Does a Monsoon Do to Your Roof?

These strong winds and rains cause a lot of stress on your roof. Monsoon rains aren’t just normal rain. These storms are extreme. The winds during a monsoon can reach up to 70 mph. During this storm, you may experience hail, which causes a lot of damage to the shingles and tiles on your roof. Even the winds alone are enough to rip off loose shingles and weaken the integrity of the seals around the fascia, soffits, and gables. The dust storms can take down trees and cover your roof in dust, further weakening the structure of your roof. Sometimes, the damage isn’t evident at first, but you may notice that your roof ages more quickly.

The Season for Storms

The monsoon season in Arizona begins in June and ends in September, the peak of the storms is in July and August. This is when Arizona receives half of its annual rainfall. Your roof already takes a beating from the heat. When the strong rains come, it can create more damage where there were small problems on your roof that weren’t addressed. Unfortunately, you can’t prevent these storms from happening, but you can be prepared when they do come.

Get Your Roof Inspected

One of the ways you can prevent damage to your roof during the monsoon season is to have an inspection in the spring. If there are minor problems that need to be repaired, you can get it done before major issues happen. This will save your roof, and potentially even save your home when the harsh rains and winds come.
