Roofing underlayment is what lies between the shingles and the roof sheathing, or roof deck, which is typically either plywood or OSB. Underlayment is installed directly on the roof deck and provides a secondary layer of protection from the elements, including rain, snow and wind. There are several different types of roofing underlayment, and each offers varying degrees of durability and quality. Why should you have your old underlayment replaced? What should you keep in mind? Expert roofing contractors from Barnett Roofing are here to help.
There are many reasons why leaving your old underlayment and placing a new layer on top of it is bad:
One fresh layer of felt is required by shingle manufacturers, and if your contractor does not install your roof according to the manufacturer’s instructions, your warranty may be voided.
To evaluate the roof decking of your home, the old felt must be removed. There could be a problem with your roof deck, such as rotting wood, that needs to be discovered and addressed before the new roof can be placed.
The cost of removing the old felt/underlayment is usually included in most insurance claims that indicate a new roof is to be installed.
Either legally or under manufacturer warranties, roof replacement and repair contractors are frequently forced to remove old shingles before installing new ones. More than two layers of roofing shingles will almost always prompt a tear-off.
Putting new shingles on top of existing ones can cause leaks and shorten the life of the new shingles, making it the best action for any homeowner since it eliminates any pre-existing issues while improving the overall roofing system. The tear-off is necessary for several additional good reasons:
Shingles can be very heavy, and having too many layers of them can pose problems, especially when their weight is compounded by things like water, ice and snow.
As was said above, the roof decking can only be adequately evaluated after a tear-off for rot, mold and other issues that could jeopardize your new roof’s integrity.
