Your roof has more to it than just the shingles on top. Beneath the noticeable exterior lies a protective layer called the underlayment that helps prevent water from entering your home.
Roof underlayment is typically made of asphalt-saturated felt, which can be made of a specialized type of paper or fiberglass. It repels water well but is not waterproof. There are also synthetic roof underlayment and rubber underlayment that offer additional protection against water damage.
Whichever type you have, the average lifespan of underlayment is 20 to 25 years. But you may notice signs of damage sooner if your roof has missing shingles or wasn’t installed properly. Read on to discover the top warning signs of damaged underlayment and what to do about it.
Damaged Shingles
Curling, lifted or cracked shingles are all signs there may be damage to your underlayment. When the shingles are not flat, they can allow water to leak underneath and damage the protective layer. As a result, your roof becomes more likely to develop a leak or mold.
Missing Shingles
Shingles that are completely missing leave your roof vulnerable to the elements. If any shingles have fallen or torn off, it’s vital that you contact an experienced, licensed roofer who can make a replacement ASAP.
Water Stains on the Ceiling
If water compromises the underlayment, then it will leak into the house through the attic. Ultimately, this can leave brown or yellow stains on your ceiling. In serious cases, you might notice wet patches or bulging puddles that are soft to the touch. Contact a professional ASAP to prevent this from leading to mold or even causing a ceiling to collapse.
Leaks
One of the most obvious signs of a roof problem is a leak. The underlayment should stop water from entering your home. When water makes it inside, this is a clear indicator that your underlayment is not working as it should.
Mold Growth
Mold growing in your home can be a result of moisture brought in by a leaking roof. Mold could also grow under the ceiling or in insulation as the leaks make their way through your property. Signs of mold growth include a musty smell, allergic reactions, respiratory illness, condensation on windows and discoloration on walls.
When to Contact a Professional
If you suspect any roof problem, it’s best to have an expert take a look. Inspections are also a good idea after any type of severe weather event or heavy winds, as these can damage shingles and leave your underlayment at risk.
