The average roof is far more complex than you would think. There are many home renovation shows now depicting just how complicated a roof problem can be, increasing the common understanding of the residential roof. Despite this, many people still think that it only consists of what they can easily see: the shingles, gutters and, maybe, the plumbing vents. But in reality, the entire roofing system is a collection of structural components that work together to effectively defend your home from weather conditions; which is especially important here in McKinney.
To combat this severe misunderstanding about the common roof we’re covering one of it’s lessen known features: the underlayment.
What is a Roofing Underlayment?
The roofing underlayment is little known aspect of the roof, but a very important one. Mostly water-resistant, it is the barrier directly underneath the top-most material on the roof. Homeowners don’t realize the importance of this additional layer until it’s time for a roof replacement. Once you notice it, you will never forget it. But what makes it so important?
- It is a moisture barrier. Moisture and roofs are a bad combination. There are many reasons why moisture seeps through the roof, including failing to switch on the exhaust fan during shower time and insufficient ventilation in the attic. So, excess moisture builds up in the air and accumulates underneath the roof, comprising structural components that are wood-based. The underlayment prevents moisture-related damage by removing water that results from condensation. This is essential for the life of your roof.
- It is water-resistant. Underlayments made from asphalt-saturated felt and non-bitumen synthetic material are water-resistant while rubberized asphalt has a sticky back that acts as a waterproof protective membrane between the underlayment and roof deck. Alleys and areas around protrusions need to be protected from water.
- It is a protection during roof repairs. Another benefit of adding roofing underlayment is having a non-slip walking surface for roofers. Roof repairs here and there are inevitable, especially after extreme rainstorms so it’s incredibly important that roofers have a smooth walking surface to protect them from accidents and further damages. Afterall without roofers there would be no roofs.
So now that you know about underlayment, do you have a greater appreciation for your roof? Roofs are some of the most complex, and underappreciated aspects of a home.
