Underlayment Failure and Its Consequences on Your Home

If you’re going to replace your old roof, you’ll need to consider a full tear-off before installing new materials. This is to prevent damage that can affect your new roofing system if they’re left intact. This includes not just your old roofing shingles and gutters, but also the inner layers such as decking and underlayment. 

Your underlayment is just as important as the rest of your residential roofing system, as it protects from the weather elements as well as insulation for your home.

A compromised roof underlayment must be replaced as it can pose certain hazards to your home such as:

Water Leaks

If you have an asphalt shingle roof that’s worn out, it won’t be difficult for water to seep through the cracks and work its way through the layers. Even if your underlayment is still mostly intact, the water can fester and pool in one area until it bursts. This can lead to water stains and rotting damage to your walls and ceilings. If you don’t want this to happen on your roof, make sure to repair the affected areas or consider a full replacement!

Compromised Structure

Water leaks and damage can also lead to wet underlayment, which can add unnecessary weight to your roofing structure. Your underlayment is designed to stay light and dry to stay effective in keeping out the elements, but if it constantly gets wet from water infiltration, it can cause further damage to your roof’s frame. You’ll end up with a sagging roof that can collapse under the excess weight! To determine if you have wet underlayment, call a trusted residential and commercial roofing contractor to check your system.

Mold and Mildew Problems

Wet underlayment also creates the ideal conditions for mold and mildew, which won’t be easily detected unless it’s regularly inspected by professional roofers. Otherwise, it will take a while until the mold infiltrates your ventilation system and compromises your home’s indoor air quality. This can trigger allergies and cause other health problems for your family.
