RICOWI to Host Underlayment Seminar on March 17

The underlayment systems play a vital role in today’s roof designs for long-term performance. The challenges of selecting the right materials, application techniques and performance criteria can be challenging to the roofing professional. RICOWI‘s Spring Seminar, which will be held March 17, 2017, in Anaheim, Calif., will provide an in-depth look at the two styles of underlayments—organic and synthetic—that might be used in low- and steep-slope roof designs. This seminar will touch upon the product designs, product approvals and code language that address how to select and properly use these various underlayment products in roof system applications.

Underlayment Speakers
Organic Underlayment: Doug Thagard, Fontana Paper Mills
Synthetic Underlayment: Mark Strait, Synthetic Roof Underlayment Institute

When underlayments are installed as part of a roof system, they may have special requirements for how they are designed, selected and installed to meet the anticipated roof performance. To better understand the relationship of the components, the speakers will cover the various styles of roof applications that will help inform the audience of best practices from the various industry associations.

Synthetic Underlayment Can Be Used on Nearly Any Roof

Based on contractor demand, Berry Plastics Co., the makers of the TYPAR Weather Protection System, launched Surround VR Underlayment, a synthetic roofing underlayment.

Based on contractor demand, the makers of the TYPAR Weather Protection System launched a synthetic underlayment named Surround VR.

Based on contractor demand, Berry Plastics Co., the makers of the TYPAR Weather Protection System, launched Surround VR Underlayment, a synthetic roofing underlayment.

Designed with the installer in mind, Surround VR Underlayment reduces the amount and weight of material needed for roofing jobs. In fact, one roll of Surround VR covers the same area as five rolls of 30# felt, yet weighs seven times less and is 10 times stronger.

The waterproof product was developed to work in nearly any roofing application, including with shingles, shakes, tile, slate or metal roofs. “With our new Surround VR Underlayment, installers will make fewer and easier trips up and down the ladder while experiencing faster installs, all while providing a more durable roofing system to their customers,” says Jorge Martinez, senior director of Product Marketing, TYPAR brand.

Made from a waterproof, synthetic polymer material, Surround VRUnderlayment is engineered to repel moisture and will not warp or buckle when wet, thus helping to maximize the life of the roof system. Surround VR is also slip-resistant on dry surfaces and provides better traction when wet.

The underlayment maintains its integrity year-round, performing well in temperatures ranging from -40 to 240 F. In cold temperatures, the material will not crack or wrinkle, which helps ensure smooth installs. In warm temperatures, its heat-reflecting, gray-colored surface reduces heat buildup on the roof. Surround VR also can withstand up to six months’ exposure to UV light and high winds and storms, even those experienced by coastal regions.

Surround VR Underlayment is backed by a 15-year product replacement warranty and is suited for residential and commercial applications.

Synthetic Underlayment Is Approved for New and Reroofing Applications

Summit 180 synthetic underlayment by Atlas Roofing offers many advanced benefits not available with conventional felt.

Summit 180 synthetic underlayment by Atlas Roofing offers many advanced benefits not available with conventional felt.

Roof underlayment is the last line of defense that protects a home from serious damage if a roof covering is blown off or damaged in a storm. Summit 180 synthetic underlayment by Atlas Roofing offers many advanced benefits not available with conventional felt. It is an approved underlayment for new and reroofing applications and can be used with most types of code-approved steep-slope roof coverings, including metal.

On certain roof projects, underlayment may face a long exposure time from the dry-in to the completed roof covering. Atlas developed Summit 180 with performance characteristics that ensure its reliability during extended uncovered exposure to damaging UV rays. This lightweight, extremely strong, polypropylene fabric contains UV and water-resistant coatings that allow for up to 180 days of open exposure before being covered.

Summit 180 can withstand extreme temperatures from -40 F to 240 F. Unlike conventional saturated felt, Summit 180 is not prone to wrinkling or buckling. This allows it to lie more flat, which helps a roof protect against invasion from water.

Roofing crews benefit from a textured, wrinkle-free top surface and a slip-resistant coating applied to the face and base surfaces of this underlayment. This dial coating slip resistance provides improved grip to allow safer walkability during installation.

Summit 180 synthetic underlayment exceeds ASTM D226 Type I and Type II, the standard specification for asphalt saturated felt. It has earned ASTM D6757, the inorganic shingle underlayment standard. It is also UL 790 compliant for fire resistance.

Summit 180 roof underlayment is packaged for convenience in 10 square rolls weighing approximately 30 pounds each. For more details on Atlas Roofing’s synthetic underlayment, contact an Atlas sales representative.

Atlas Roofing, a producer of felt underlayment, produces a lightweight, synthetic alternative to organic felt known as Summit 60. This underlayment, manufactured from strong woven polypropylene fabric, offers advanced benefits not available with traditional felt.

Summit 60 Synthetic Underlayment, which has high-temperature stability and offers greater resistance to UV breakdown than felt, has the durability needed for jobs that have a long open time from the dry-in to the completed roof covering. On certain steep-slope roof projects, underlayment can sometimes face such exposure for up to 60 days. For these roofing projects, underlayment must be able to maintain its reliability; Summit 60 meets these demands.

Roofing crews will appreciate that Summit 60 has a textured wrinkle-free top surface fabric and a slip-resistant polymer coating applied to its bottom surface, for safer walkability during installation. This slip-resistant polymer provides improved grip for reduced slippage between the underlayment and the roof sheathing.

Installation is easier because Summit 60 is manufactured with pre-printed lay lines. This water-resistant underlayment is packaged in 10 square rolls, each weighing less than 30 pounds. It provides more coverage per roll than traditional felt.

Summit 60 Synthetic Underlayment can be mechanically fastened to many different types of substrate, making it a solid underlayment choice for both new and re-roofing applications. This excellent synthetic product can be used with asphalt shingles, clay and concrete tiles, slate, and wood shakes, or any other code-approved steep slope roof covering.

Summit 60 underlayment has earned ASTM D6757, the inorganic shingle underlayment rating standard. Its performance exceeds ASTM D226 Type I and Type II, the standard specification for asphalt saturated felt and it is UL Classified as demonstrating conformance to critical fire testing requirements for a prepared roofing accessory. It also received FL 16226, the Florida Building Code approval.

Designed to enhance the life of a roof, Summit 60 qualifies as an Atlas Signature Select Roofing System component. Atlas Signature Select Roofing Systems are offered at three system levels allowing contractors to target all market segments.
