A roof’s effectiveness depends on quality elements that are fixed and performed properly. You endanger the roof’s lifetime by missing a stage or employing inferior materials.
Roofing underlayment is indeed an important component in maintaining the longevity of your roof. Though there are various varieties to select from, synthetic underlayment has become the most prominent and favored choice in the building and construction industry because of its greater performance and lifespan.
To give you a clearer idea of whether synthetic roofing underlayment is right for you, we cover the top three problems with synthetic roof underlayment and why that may not be the best choice for a project in this article.
What Is Synthetic Roof Underlayment?
Synthetic underlayment becomes a roofing component made of polyethylene plastic or lamination polypropylene which fits out over the rooftop deck and provides an additional coating of weather protection for a roof installation. Because the substance does not retain water, it has a long lifespan. As a result, it is the ideal material for drying on a roof.
Synthetic underlayment may be affected by environmental factors for a limited time without being harmed. The time range differs depending on the manufacturer of the underlayment.
Problems With Synthetic Roof Underlayment
There are 3 issues with this kind of roof underlayment that you must be concerned about. Usually, those are connected with the felt ones. But, to further understand the information, it is better to check these points below.
One of three problems with synthetic roof underlayment that you should be mindful of is the expense. The synthetic underlayment can be substantially more expensive than just a felt underlayment. Non-adhesive polymer roof underlayment costs between 17 and 25 cents per square foot.While felt underlayment costs between 5 and 10 cents per square foot.
However, synthetic underlayment can be twice as expensive as felt underlayment. It possesses a significantly higher long-term value. It simply does not make sense to purchase a costly roof system and install a cheap underlayment that is not meant to last the lifetime of the roof installation.
When you consider the whole expense of a 2500 sq ft roof, then changing out of a felt underlayment to something like a decent value non-adhesive underlayment is only 3 to 4 hundred dollars.
- Mil Thickness vs. Weight
This second issue is about synthetic vs. felt underlayments, as not every synthetic underlayment is made equally. There are several slightly elevated synthetic underlayment manufacturers, though there are several duds that aim to dupe you with flashy marketing and a mediocre product.
When looking at the products or getting the best synthetic roof underlayment, you should look at the entire roll weight. It is also essential to check and somewhat split the item apart to see what you are truly obtaining from such a water-resistant membrane standpoint. When you tear the item up a little bit, you can even know that you do not have much of what you assumed in the beginning.
- Some Building Codes Do Not Allow For Synthetic Underlayment
The final problem with synthetic roof underlayment is that synthetic underlayment is not permitted in all construction regulations. It will be difficult to find a construction code that does not support it, yet it is always a great way to test your current building rules and ensure that synthetic underlayment is permitted.
Ensure that you consult the building standards before making any decisions regarding roof underlayment. The building code can stipulate whether or not underlayment is necessary and the type of underlayment that should be utilized. Although it is uncommon, there are rare cases where synthetic underlayment is prohibited, and felt roof underlayment must be used.
