The current state of underlayments could be summed up in three words, “better than ever,” according to Tom Metoxen, Manager of Technical and Warranty Services for Carlisle Residential.
The variety of finished roofing products can dictate what must be used as an underlayment, said Metoxen, noting that with metal roofing a heat resistant or high temperature product must be used. “Different climates can also require the use of a specific underlayment,” he said.
““Underlayments provide a vital layer of protection on top of the sheathing to help keep moisture out of the building, and are considered a necessary piece of the roofing structure,”” Mass said. “The advancements made in roofing systems and roofing underlayments lead to a stronger, longer-lasting roof that holds up better against weathering.”
UV exposure time limits depend on the type and surfacing of the membrane.
Atilla Sebuktekin, GAF-Elk Vice President of Marketing for Steep Slope Roofing and Decorative Stone Products, said the industry has trended towards better quality underlayments for roof deck protection over the years.
GAF-Elk recognizes the growing need and is promoting such products as Deck Armor Premium breathable underlayment as part of a complete roofing system.
Synthetic underlayments continue to grow at the expense of traditional asphalt felt paper, said Sandro Di Pede of SDP Advanced Polymer Products. “The cost gap between synthetic and felt is reducing, thus helping to generate additional interest and trial of synthetics,” Di Pede said. “But what is key - to synthetic acceptance and continued growth - is safety with respect to walkability on pitched roofs, especially in wet, dusty, contaminated conditions.”
Ratcliff said many types of self-adhering and synthetic underlayments have been introduced over the last 10 years, with the addition of specialty products designed for specific roofs and climates. As a result, the underlayment product category is gaining tremendous respect. “Labor savings coupled with superior performance will encourage most contractors to offer premium underlayment to customers as standard rather than as an optional upgrade,” said Ratcliff. “The superior dry-in benefits and UV resistance of premium underlayment gives contractors greater flexibility in scheduling primary roofing system installations. The secondary water barrier provides extra protection when the primary roof fails for whatever reason.”
Edward Sueta, marketing manger at ALCO-NVC Inc., said the key ingredient to the success of underlayments is the ice and water protector used under shingles, metal and slate. “They come in smooth, granulated and a high temperature version for under metal,” Sueta said. “Future generations must consist of a hybrid that is synthetic and able to seal around nails, metal fasteners and metal screws - one that can do it all.”
