10 Common Roof Problems
You may be optimistic about the life expectancy of your roof but there are common roof problems that can significantly impact your home. The secret to getting longer life out of your roof is to catch problems early. In order to achieve this goal, it helps to have a better understanding of the problems likely to affect a roof at some point. Here are ten of the most common roofing issues to look out for.
1. Leaks and Moisture
Whether it’s rain, snow, hail, or ice, there are many forms of moisture that can damage various parts of a roof. Depending on where water or moisture gets to within a roof, it can cause leaks, mold growth, and/or rot.
2.Improperly Installed or Damaged Flashing
Flashing is what seals areas where there are roof profusions like chimneys, skylights, and vents. If flashing is either damaged or not properly installed, it can cause seams to open, shingles to loosen or fall off, or leaks to develop. Weak, worn, or improperly installed flashing can also reduce puncture resistance.
3.Punctures and Penetrations
Strong winds and severe storms can send debris from nearby trees flying onto your roof. If branches, twigs, and other items hit your roof at the right angle, the result can be punctures and penetrations. Powerful hailstorms can be another source of roof punctures. The most effective preventive measure is to trim and prune trees around your roof’s perimeter.
Squirrels, birds, and other critters and creatures can do some serious damage when scampering across a roof or trying to nibble at shingles or flashing. Nests in gutters can also create backups and cause water to accumulate on your roof.
Shingles can blow off from strong winds or during strong storms. Fortunately, this is a problem that’s usually easy to fix by either reattaching shingles or replacing ones that were damaged when they blew off.
6.Snow and Ice Damage
Over the years, snow and ice can take its toll on a roof. Melting snow and ice can seep underneath shingles and cause leaks. Rapid freezing and thawing cycles can also cause flashing or shingles to lift.
7.Shrinkage and Blistering
Shrinkage occurs when a roof membrane shrinks and causes shingles to crack or loosen. While sometimes considered a manufacturer’s defect, blistering is usually caused by issues with roof-related ventilation.
Eaves and soffits naturally help maintain roof and attic ventilation to allow for a balanced flow of warm and cool air. However, if ventilation is disrupted or not set up properly, your roof may be damaged by heat and moisture buildup. Insufficient airflow can also contribute to mold problems.
Water that remains in place on a roof is referred to as “ponding water.” Water accumulation can be caused by insufficient drainage, debris buildup, or drainage issues around HVAC units.
10.Poor or Faulty Installation
A roof that was never installed right in the first place is one that’s more likely to have problems. If you’re not sure whether or your roof was properly installed, a contractor can perform a thorough roof inspection to give you a better idea of the overall condition of your roof.
Some roof problems, like a few blown-off shingles, may be do-it-yourself fixes. However, most of the time, it’s best to call on a professional to size up the problem and recommend an appropriate solution. You’re also less likely to have homeowner’s insurance issues if you have repairs professionally handled. Plus, contractors are trained to safely access a roof.
