How Moisture Causes Damage to Your Roof

A high-quality roof installed by a reputable roofing contractor will protect your home from the elements for at least 20-25 years. However, whatever quality of roof you have, it is not going to last forever. And if you want it to reach its expected life span, a reasonable amount of maintenance is crucial.

The primary reason for roof upkeep is to prevent water damage. Water is your roof’s primary enemy, and if it is given even a tiny way to enter your roof, there’s no telling how much damage it can wreak before you even notice that something’s wrong.

Here are the ways water damages a roofing system:

Presence of Moisture and Condensation

This is something you should remember: not all roof water damage is directly caused by rain, snow, or ice. Moisture can come from within your home, as well. Your home produces heat from the HVAC, people, pets, cooking, refrigerators, dishwashers, bathtubs, showers, washing machines and dryers, and other things, including your TV and other appliances. Warm air holds water very well. When all of that heat is trapped in your roof through the attic, the moisture in the warm air condenses when it hits the roof. During winter, it turns into frost, which will melt with a warm snap.

This will lead to the presence of water underneath your roof. Moisture causes mold growth, ceiling and wall stains, corrosion, wood rot, and other problems. Excess moisture can loosen shingle granules. Termites, cockroaches, and other unwelcome guests love dark, moist places.

To prevent this problem, make sure to have a professional perform any necessary roof repair. This can include removing insulation that has blocked the roof ventilation system and adding insulation in the proper areas. Pro tip: never block your roof ventilation during winter. To prevent drafts from entering your home through the attic, improve your insulation.

Damaged Shingles

Asphalt shingles are some of the best types of roofing materials. However, time and the elements combine to give them problems. For example, while they may look fine at first glance, your shingles might already have deep cracks or a few popped blisters courtesy of the sun’s heat. Flashing may be loose or blown off. These types of damage can allow water to penetrate your roof.

How This Relates to Your Health

It’s not just your roof that’s at risk here or the rest of your home and your belongings. You and anyone who lives with you can also be affected healthwise. The presence of mold and mildew in your attic can lead to spores in your home, transported to every room via your HVAC ductwork. This is a common cause of allergic reactions and respiratory illnesses. Mold and mildew in your attic will not stay there. Through their spores, they might already be present in your cabinets, crawl spaces, basement, bathroom, and other dark and damp areas in your home. Removing mold and mildew is a professional’s job.
