There is more than meets the eye when you are looking at the roof on your house.
We never take the shingles on our home for granite. They are attractive, colorful, and essential. They are dutiful, assuring us that they are protecting us and our home from all types of weather. They protect us from the heat, cold, rain, and the snow. They are our covering…our protector.
Though we may give those shingles credit for all they do, there is a little known secret that is not given the credit it deserves and most of the time is taken for granite. Roofing felt.
Sandwiched in between the decking and the shingles is a very important material… felt. There are generally two types of felt used in roofing. One, traditional felt, is made from taking heavy duty felt and saturating it with asphalt for waterproofing, which is often called “Tar Paper.”
The second is a synthetic underlayment made of polypropylene. It boasts of being six times lighter and three times stronger than traditional felt. It is impervious to moisture and offers a higher degree of weather protection, which is why many roofers prefer it to “Tar Paper.”
Even though you cannot see the felt after the shingles have been installed it is hard at work providing a second barrier of protection for your home. Its main purpose is to protect your roof decking from any moisture that might somehow find its way underneath the shingles. The felt’s added protection assures the homeowner that the chances of water damage, mold, and wood decay are greatly minimized.
Roofing felt also prevents wood resin from bleeding through decking into the shingles causing ugly stains on your expensive shingles. It can not only become unsightly but it can also put your shingles at risk. No one wants to pay thousands of dollars for expensive shingles only to cause your home to be an eye sore for the entire neighborhood.
Many times during severe weather shingles may be blown off leaving the roofing felt exposed in the vacancy of the shingle. Because the roofing felt repels water, it can protect the roof decking and often the interior and the contents of the home from water damage, until the shingles can be replaced. It is a great backup for a potential disaster.
Felt enhances the overall appearance of your roof by providing a smooth surface for your shingles to be installed on. Your home should not only look good because of your roofing shingles but you should also have peace of mind knowing that that unseen layer of felt underneath those shingles has you covered.
So if you’ve never thought about the process of roofing, and the quality products designed to maximize the enjoyment of your home, now you know one of the little secrets of the unseen. Just think of it as a security blanket tucked in between your shingles and your decking.
I hope you haven’t “felt” like I’ve gone “over the top” on this article.
