Monsoon Season Roof Repair

Colorado’s monsoon season begins in July and continues through September. The season is characterized by afternoon thunderstorms that, as part of the North American Monsoon, are rather persistent. Heavy rainfall, lightning, and flash flooding are commonly associated with the NAM. Often severe and unpredictable, these storms can damage shingles, regardless of the roof’s age. Leaks are also quite common during the season’s heavy rainfalls. Damaged or missing shingles and roof leaks, resulting from the monsoon season, require professional roof repair.

What is Monsoon Season?

The North American Monsoon, more simply known as NAM, is a shift in the wind pattern that brings moisture from the Gulf of California to the southwest. It occurs during the summer in Arizona, New Mexico, and Colorado. Daily thunderstorms – complete with heavy rainfall, lightning, flash flooding, and hail – are usually par for the course (Colorado Climate Center, 2020).

Common Repairs Needed after a Storm

Roof Leaks

Hail, depending on its size, may puncture a roof and cause leaks. Heavy rainfall can also make an existing leak more noticeable and lead to more significant damage. These are often identifiable by water spots/stains, moisture in the attic, wet roof decking, mold growth on the shingles or in your attic, and more. Because the exact source of roof leaks can be hard to spot, it’s a good idea to contact a professional roofing contractor for an on-site inspection and consultation.

Missing Shingles

Excessive winds can cause shingles to blow off your home. That can leave the roof’s underlayment exposed and vulnerable to hail, debris, and tree limbs. There is the potential for more severe problems to occur if the missing shingles are not quickly replaced. Jenesis Roofing can determine the extent of the damage, including the number of missing shingles, and provide you with their expert roof repair recommendation.
