Rainwater is one of your roofing system’s biggest adversaries, as it can inflict numerous types of damage. Without timely leak identification and repairs, water damage can cause wood rot and mold growth, both of which contribute to structural instability. Leaks can also make their way into your attic, uppermost ceiling, and adjoining walls, causing further rot and fungal growth. Learn about top roof leak causes here to help your system remain dry and safe.
Why Do Roofing Systems Leak?
1. Clogged Gutters
Without routine cleaning, gutters become clogged with leaves, twigs, bark, shingle granules, tree nuts and seeds, and other organic debris. Clogs prevent rainwater from flowing off your roof into gutters and the connected downspouts, making it back up under shingles instead and causing leaks.
Clean your gutters at least twice a year to prevent damaging clogs, or more often if your home is surrounded by numerous trees. You can also have leaf guards installed that prevent large debris pieces from entering the gutters and allowing quick debris buildup.
2. Missing Shingles
Storms often result in missing shingles, such as those ripped off the roof from high winds or broken in pieces from tree branch impacts. Even one missing shingle increases leak chances because it exposes the underlying materials, such as felt underlayment, to the elements. When the underlayment wears away, it reveals the roof rafters and leaves your home vulnerable to leaks, mold growth in the attic or crawlspace, and pest infestations.
Use binoculars to inspect your roofing system after every storm for broken and missing shingles, and look around your perimeter for pieces scattered about to schedule the appropriate repairs. Also, keep tree branches trimmed back so they cannot slam into roof shingles.
3. Damaged Flashing
Metal flashing surrounds roof protrusions, such as your chimney and air vents, to prevent leaks. Eventually, the material corrodes from exposure to oxygen and water, which weakens and corrodes it. Storms can also cause flashing damage, such as dents and dings from heavy tree branches blowing in extreme wind. No matter why roof flashing sustains damage, it no longer provides protrusion protection and creates gaps that allow rainwater in.
Check the condition of the flashing after every storm with your binoculars, and have it replaced if you notice large cracks, rust, or sections that have been lifted from dried-out roof tar or other sealants.
