Looking For “Roofing Supplies Near Me?” Try Synthetic Underlayment!


Firstly, let’s discuss what an underlayment is and what purpose it serves. The underlayment of your roof is there to serve a number of important purposes. It acts as a non-slip walking surface as protection for roof installers so that they don’t fall. The underlayment protects the roof from rain or other moisture if there is rainfall prior to the roof being fully installed. It acts as a water barrier in the case of roof damage in a storm, and also prevents the leaching of chemicals from asphalt shingles onto the roof deck and adds an extra layer of protection from heat and sound outside of your house. The two main types of roof underlayments are asphalt felt underlayment and synthetic underlayment. The majority of synthetics are spun or woven from either polypropylene or polyethylene. The specific manufacturing process produces synthetic underlayments with different properties such as the thickness, exposure time, and resistance to damage throughout the installation process, etc. Synthetic underlayments utilize grams-per-square meter (GSM) as their measurement.


Benefits Of Synthetic Underlayment

  • Synthetic underlayment is a lot lighter than felt underlayment, meaning that using synthetic as an effective water barrier adds less weight to the roof than asphalt felt underlay.
  • Since it is so light, synthetic underlayment is a lot easier and safer to install than asphalt felt. 
  • Synthetic underlayment is a lot more tear-resistant when exposed to high winds and foot traffic than asphalt felt underlayment.
  • Due to the fact that synthetics don’t absorb any water, they are resistant to fungal growth and are wrinkle-free.
  • Synthetic underlayments are ultraviolet (UV) resistant for between six and twelve months, whereas sunlight exposure degrades asphalt felt. 
  • Its integrity is maintained when exposed to cold weather, while asphalt felt can wrinkle when wet and cracks in cold weather.
