Common Roof Damage from Excessive Rain


Have you noticed any leaks, damp spots, or sagging areas on your roof after a bad storm? If so, you’re not alone. Excessive rain can really do a number on your roof, causing all kinds of damage. In this article, we’ll walk through some of the most common types of roof damage caused by heavy rainfall.

Our Charleston roof repair specialists explain how to identify issues like water stains, pooled water, and loose shingles so you know what to look out for after the next big storm. Arm yourself with the information you need to keep your roof in its best shape, rain or shine.

Shingle Damage

The constant pounding of heavy rain can damage your roof shingles. Loose or missing shingles are common, as the water seeps under the edges of shingles and breaks the seal of the asphalt tabs holding them in place. You may notice shingles sliding out of position or even blowing away, leaving holes in your roof coverage.

Cracked or split shingles are another issue caused by heavy rains. As water saturates the shingles, tiny cracks form and expand under the weight and force of the water. These cracks then allow more water to seep into your attic space or living area. Unfortunately, cracked shingles cannot be repaired and must be replaced.

Mold and Decay

With excessive rain comes trapped moisture, and this means big trouble for your roof. As rainwater flows over your roof, some of it seeps into tiny cracks and holes. This water then becomes trapped, unable to evaporate in the hot sun. The trapped water creates the perfect environment for mold, mildew, and rot to grow.

Mold spores are always present in the air, just waiting for the right conditions to land and propagate. The longer the trapped moisture sits, the more mold will grow between your shingles, underlayment, and sheathing. This mold weakens these materials, causing them to decay and break down over time.

Leaks and Cracks

A leaky roof means water is finding its way into your attic or living space. Leaks often start small, like a drip you notice during heavy rain, but they can lead to much bigger problems if left unaddressed. Water that leaks in can cause damage to insulation, drywall, wood, and wiring. It also provides an entry point for insects, mold, and mildew.

The source of leaks can range from small cracks or holes in shingles to issues with your roof’s flashing or vents. The flashing and vents on your roof, like pipes, skylights, and chimneys, are common spots for leaks.

The flashing is the material used to seal and weatherproof the joints and seams where different parts of the roof meet. Damage or deterioration of the flashing can allow water to get in. Vents that are not properly sealed or caulked can also lead to leaks.

Gutter and Downspout Damage

Your gutters and downspouts work hard to direct water away from your roof and foundation. After heavy rains, however, clogs and cracks can form, causing water damage in unexpected places. When gutters fill up with leaves and debris, water can overflow and seep into your attic or basement. Make it a habit to clean out your gutters at least once a season, or hire a pro to do it for you.

They have the proper equipment to safely reach and clear even the trickiest of gutters. If it’s been a while, have them inspected for any minor damage that could lead to leaks or further clogging. An ounce of prevention is worth a pound of cure when it comes to avoiding costly water damage to your roof and home. Staying on a seasonal maintenance schedule will help keep your gutters flowing freely and doing their job.
