The Importance of Replacing Your Roof’s Old Underlayment

Your roof plays an essential role in your home’s aesthetic appeal and functionality. Thus, you must see to it that it is in good condition to ensure its optimal performance. Austin Pro Siding, Windows & Roofing, one of the top roofing and vinyl siding contractors in the area, explains why you need to replace your old roof underlayment.

The Importance of Your Roof Underlayment

The asphalt shingles or metal panels of your roof protect your home against the harmful effects of moisture and UV rays. However, some areas of your roof aren’t protected, resulting in gaps where debris, water and the other elements. This is where the underlayment does its job.

It acts as your roof’s secondary barrier, shielding the deck, rafters and trusses from rot while providing stability to the whole structure. Reputable roofing and window companies make sure to install it to manufacturer specifications to maximize its effectiveness.

Why Should You Replace It When It Gets Old

Simply put, an underlayment that is past its service life no longer offers the protection necessary for your home. The same goes for the rest of your roof components, including the flashing and shingles. Be sure to have them inspected by experienced roofers so you can determine whether it needs to be replaced. If they do recommend a replacement roof, see to it that they perform a complete tear-off.

Some roofers leave the old roof covering and the underlayment and place a new one over it. It is called a roof overlay, and it only works when these components are still in good condition. A roof that is past its service life can have underlying issues underneath the shingles and underlayment, which is why a complete tear-off is done before installing the new roof.
