There are 2 main types of underlayment out there: Natural and synthetic.
If you want to learn more about the differences between the two, keep reading. If you just want to speak with someone who can help you with roof installation in Graysville, TN give us a call now at 423-493-3636.
Each has a lot of benefits to support your roof’s structure that you might want to know more about. Of course, if you’re wondering what underlayment is you’re also in the right place.
The Purpose of Underlayment
If you’re unfamiliar with the anatomy of your roof, there’s a space between the wooden deck of your roof and the materials on top. In that space is where underlayment goes, to protect against leaks and water seepage.
It’s an important component, in case there’s a shingle that falls off or a nail that comes out during a storm. When that happens, the underlayment is built to absorb and act as a buffer between the weather and your wood.
That’s why the choice between types should be done with care. Some factors to keep in mind when making your decision are where you live, your roofing, and how much you’re willing to spend.

One With Nature
Natural underlayment is made out of felt, which has been used for years as a testament to its success. However, it’s important to know that there are 2 versions of felt underlayment that vary in strength.
No. 15 is the standard underlayment for most budgets, but No. 30 is a thicker material. That means it can absorb more and withstand a lot more wind and weather damage if the surface materials are missing.
Either choice is a solid one, because felt is generally more affordable and provides ample protection between your roof and the outside world. Still, it’s also important to know some of the cons associated with felt.
Once exposed, felt has a tendency to pull in moisture naturally which can diminish how much protection it offers. That means you’ll have to replace it soon after, but the good news there is that what you save with felt will probably still be well within your budget.
As a homeowner, the first thing you’ll want to do before making a choice is to check your agreement. Some areas don’t allow felt underlayment and some roofing warranties are voided unless synthetic is used, so it’s good to know beforehand.

Advanced Underlayment
Where felt has withstood the tests of time, a modern approach to roofing is synthetic underlayment. This combination of polymers is meant to hold up against the weather and water with long-lasting and extra-strength capabilities.
On top of taking a lot of wear and tear, it installs faster which translates to a lower contracting cost usually. Synthetic underlayment also tears less easily than felt, but with the good comes the bad and there are a few things to be aware of.

Manufacturing of synthetic underlayment isn’t across the board, so some have higher quality than others. As with any questions you might have, contact VLR Homes if you want to know more about a specific product.
You might see the strength and longevity of synthetic underlayment and think it’s automatically better than felt, but the difference in price is a huge disadvantage. It might be stronger in most cases, but you’ll pay for that protection whereas you can replace felt and still be under the price.
Basically, felt is a fantastic, time-tested option for any budget that holds up well and synthetic underlayment costs a pretty penny that provides benefits for your roof. Either one requires consideration and VLR Homes is here for any questions and a free estimate!

VLR Homes, LLC



We have engaged Francisco and VLR Homes 3 times now. From painting the house, remodeling a master bath and constructing a screened in porch area they have responded with quality work at a fair price. When things came up like they always do, VLR had a solution (some panels of 50 year old siding replaced with Tyvek and up to code replacement). Again, at a fair price and done right the first time. Francisco is responsive with the good and the bad news straight up and always with a plan. We intend to use VLR in the future for projects large or small.
