Expanded and Enhanced Flashing Tapes Available in New Sizes

Huber Engineered Woods provides problem-solving innovations as teams and codes continue to make strides toward tighter building envelopes. A revolutionary new approach to building enclosures, ZIP System sheathing and tape for roof eliminates the need for felt with an integrated underlayment that protects against water penetration as an all-in-one continuous water and air barrier. Panel seams are taped with advanced acrylic ZIP System flashing tape for a strong sealed roof deck.

ZIP System building solutions, made by Huber Engineered Woods, transformed structural envelopes by introducing the first integrated sheathing system that eliminates the need for housewrap and felt in wall and roof assemblies, notes the manufacturer. The engineered-wood systems streamline installation with built-in, continuous air and water-resistive barriers. A line of integrated panels that also incorporate exterior insulation is available in varying R-values within the ZIP System family of sheathing and flashing products.

In 2019, the ZIP System line of sealing solutions was expanded and includes an enhancement to ZIP System straight flashing tapes to include three new sizes of ZIP System flashing tape and three new sizes of ZIP System stretch tape. The enhanced formula can be applied between 0 degrees and 120 degrees Fahrenheit. ZIP System sealing solutions now include five ZIP System stretch tape options and five ZIP System™ flashing (straight) tapes.

The ZIP System flashing tape is now available in these sizes:

  • New – 3.75” x 30’ – A shorter roll for smaller projects
  • New – 9” x 50’ – Used for wider areas like thicker, insulated ZIP System R-sheathing outside corners
  • New – 12” x 50’ – A single-piece roof valley sealing solution

Atlas Roofing’s Summit 60 Underlayment Goes Pink For Breast Cancer Awareness

In honor of breast cancer awareness, Atlas Roofing’s premiere lightweight synthetic roofing underlayment Summit 60 is going pink, with a portion of the sales proceeds to support the Susan G. Komen breast cancer foundation.

For every roll of Summit 60 sold — including traditional and limited-edition pink ribbon rolls — from Aug. 15 to Oct. 15, 2019, Atlas Roofing will donate $2 to the foundation. The Summit 60 Pink special-edition rolls will be embellished with pink branding and pink ribbons, the international symbol of breast cancer awareness. The special-edition Summit 60 will be available to contractors exclusively through Atlas Roofing distributors.

Tracy Cook, director of marketing for Atlas, said the special-edition rolls are aimed at bringing more attention to breast cancer, including early detection and research for a cure. For Cook, the cause is close to her heart. Her mother had breast cancer in the early 1990s.

“Treatment has come a long way since 1991, but it has a long way to go. Indeed, early detection is key,” Cook said. “Many of my family members have had cancer — breast, lung, oral and prostate. In every case, it’s about early detection.”

Designed To Protect
Summit 60 is designed to optimize the life of a roof system through superior water resistance and UV protection, protecting against water intrusion and mold growth. Made from a woven polymeric scrim, Summit 60 is designed for increased strength, reduced slippage between the underlayment and the roof sheathing and improved walkability during installation. The materials will not warp, buckle or crack over time like other organic felt brands. The UV coating provides 60-day protection from the sun while the roof is being installed.

Supporting Cancer Research And Early Detection
The Susan G. Komen foundation launched in 1982 and has since funded more than $988 million in research and more than $2.2 billion in education, screenings and treatment programs. Due to the worldwide efforts by the foundation and others, breast cancer mortality has declined 40% from 1989 to 2016.

However, more work needs to be done. Today, about 12% of women (or 1 in 8) will develop invasive breast cancer in her lifetime. In 2019 alone, an estimated 268,600 women and 2,670 men will be diagnosed with invasive breast cancer. An estimated 41,760 women and 500 men will die from breast cancer in 2019.

“Cancer of all types has touched everyone in the United States in one way or another. Since breast cancer is one of the most commonly diagnosed cancers among American women, it has impacted so many of us,” Tiara Searcy, content and digital marketing manager for Atlas Roofing, said. “We hope our efforts with Summit 60 will help make for a healthier future.”

Partners In Pink
Atlas Roofing is proud to help in the fight against breast cancer and supports the outstanding work of the Susan G. Komen foundation.

“The goal of our pink campaign is to provide much-needed funding for critical research and public education,” explained Kirk Villar, vice president of sales and marketing for Atlas. “We are honored to join forces with the community to take a stand against breast cancer.”

Summit 60 Pink will be available across the country. For more information, contractors should contact their Atlas Roofing representative.

Vapor Permeable Underlayment Designed for Use on Steep-Slope Roofs

VaproShield announces the release of SlopeShield Plus Self-Adhered, a highly vapor-permeable roofing underlayment Air Barrier (AB) material. SlopeShield Plus Self-Adhered (SA), a vapor permeable roofing underlayment, is designed for use on steep slope roofs of 2:12 or greater pitch. According to the manufacturer, the roofing underlayment features the patent-pending Vapor Permeable Polymer Composite Technology (VPPCT) developed by VaproShield.

“VPPCT combines advanced polymer coatings and our proprietary adhesive to create a primerless, highly-permeable, and fully-adhered [roofing] underlayment that is revolutionary to the industry. The black color also absorbs heat from the sun (while exposed), which increases the drying process of wet sheathing and insulation,” said Kevin Nolan, Technical Director of North America. “Every part of SlopeShield Plus, including the color, was intentional.” 

The development of SlopeShield Plus Self-Adhered came from an existing market demand for a high-performance and permeable roofing underlayment. Traditional asphaltic and butyl-based peel-and-stick roofing underlayments offer liquid-water holdout but lack drying capacity due to their non-permeable nature. These underlayments inherently trap moisture, reducing insulation performance and accelerating sheathing decay-potentially causing premature roof assembly failure.

“The industry has had traditional [asphaltic and butyl-based] underlayments for years. We are always working to push the industry forward,” noted Lee Snyder, Managing Partner of VaproShield.

SlopeShield Plus Self-Adhered offers superior performance to the polypropylene tri-laminate micro-porous permeable existing roof underlayments. The superior construction technology of SlopeShield Plus Self-Adhered is a composite of polymers and polyester in a sheet good that allows vapor diffusion. According to the company, the design of SlopeShield Plus Self-Adhered eliminates the water leakage created by the concussion effect (caused by heavy rain and foot traffic) while allowing for 6-month UV and climate exposure prior to roof system installation.

SlopeShield Plus Self-Adhered is compatible with metal roofing, slate/clay tile with batten/counter-batten substructures, and cedar shingles/shakes with VaproMat. VaproShield offers SlopeFlashing in two sizes: 29.5 inches and 19 2/3 inches. SlopeFlashing is used to flash eaves, hips, ridges and valleys.

Combining SlopeShield Plus SA and VaproShield’s vapor permeable WRB/Air Barrier wall membranes will create an airtight and watertight building enclosure that offers high drying capacity for the building envelope and roofing assembly-mitigating moisture damage and saving energy for the life of the building. A National Institute of Standards and Technology (NIST) study (NISTIR 7238) showed that an effective air barrier can reduce a building’s energy costs by as much as 40 percent and electrical costs by more than 25 percent.

Expert Tips For Shingling A Cone-Shaped Roof

Cone-shaped roofs are one of those projects that contractors either love to do or avoid like the plague.

A prominent architectural feature on Queen Anne- and Norman-style homes, cone-shaped roofs are also found on Armenian and Georgian churches and medieval towers and castles. Their sloping and curved geometric surfaces can be difficult and labor intensive to shingle, especially for roofers who are accustomed to working only with straight lines.

Whereas a simple pitched roof typically has two or more sides and a hip roof has at least four sides, a conical or turret-style roof can appear to have an infinite number of sides. Some cone-shaped roofs have three to eight flat sides that create more of a geometric shape, such as a pyramid.

So, the challenge is: How do you install flat shingles on this intricate, rounded surface?

The underlayment should be applied vertically, perpendicular to the eave, as shown in this figure from the ARMA Technical Bulletin titled “How to Shingle a Cone Roof.” (Copyright Asphalt Roofing Manufacturers Association, reprinted with permission.)

Getting Started

Thanks to their flexibility, modern asphalt shingles can be installed on roofs of any shape.

To begin shingling a cone roof, you need to know three measurements: the length of the rafter, the diameter of the cone and the widest piece of shingle you’ll be using.

To determine the distance around the base of the cone, multiply its diameter by 3.14. For example, if the diameter is 20 feet, the perimeter would equal 62.8 feet. With a 12-inch-wide shingle, you would need 63 shingles in each row around the cone.

Precise calculations are necessary because shingle pieces will need to change shape and become narrower as you move from the base of the cone up to its peak.

Cutting the shingles is a task you can do ahead of time, by creating a template, or when you get to a particular part of the installation.

Safety Concerns

Because cone-shaped roofs are usually steep and high off the ground, consider hammering footholds into the roof for stable support while you work. Better yet, use scaffolding, which not only provides a platform for leaning a ladder onto the roof, it also serves as an easily accessible shelf for your roofing materials and tools.

On a flat-sided cone roof, use the standard hip and ridge installation method. (Copyright Asphalt Roofing Manufacturers Association, reprinted with permission.)

Underlayment and Ventilation

With preparations complete and safety equipment in place, you’re ready for the fun part: installation.

First, start by applying a good quality underlayment to the deck per the manufacturer’s instructions.

The underlayment should be applied vertically, perpendicular to the eave, following the flow pattern from the cone’s peak to its base. This process will help to prevent the material from wrinkling or buckling. You should end up with an overlap near the peak, which can be trimmed during underlayment application and before installing shingles.

Continue to overlap the underlayment vertically as you progress up the cone and use asphalt plastic cement to cement the lap edge. Alternatively, you can use a peel-and-stick underlayment. A self-adhering underlayment protects the eaves and flashing from wind-driven rain and covers any possible gaps between abutting shingles.

Next, check the ventilation. If the cone is open to the attic area, it should be part of the ventilation system. To accommodate static ventilation in the main portion of the attic, increase the requirement for the net-free area by the same square footage as the cone-shaped room. If the area is open to the living space, a ceiling fan can help force moisture and heat from the cone-shaped room to the main living area for dispersal. Using a room dehumidifier may also be helpful.

When working with a completely circular cone, use an off-peak, roll-type ridge vent at the peak for positive ventilation. The formula for cone-shaped rooms is consistent with any other residential area:

  • Equal intake and exhaust vents: 300 square feet of attic area = 1 square foot of net-free vent area
  • Exhaust vents only: 150 square feet of attic area = 1 square foot of net-free vent area

In cases with no ventilation, make the homeowner aware of potential issues with accelerated wear and how it can affect the product’s warranty. For more specific requirements, contact the shingle manufacturer.

Shingling Flat-Sided vs. Rounded Cones

After installing underlayment and addressing ventilation, you can start applying shingles.

When shingling a rounded cone roof, divide the roof into three distinct zones. (Copyright Asphalt Roofing Manufacturers Association, reprinted with permission.)

If you’re working with a flat-sided cone roof, you can use the standard hip and ridge installation method. Snap vertical chalk lines from the cone tip to the eave center on each of the flat sides. Then apply shingles to the flat areas, cutting at the hips or joints. Use a standard hip and ridge shingle to complete the hip joints.

To ensure a continuous roofing line, snap horizontal chalk lines around the cone so that shingles will line up on adjacent sides.

Shingles on steep-sided cone roofs — those greater than 21/12 slope — may need to be hand sealed with asphalt plastic cement. Check the manufacturer’s instructions for steep-slope application.

When shingling a rounded cone roof, you won’t have a horizontal line to follow because of the curvature. If you try to create a line, butting the sides of the shingles together, the shingles will gradually curve downward and won’t correctly align when you encircle the cone.

To make installation easier, divide the roof into three distinct zones. Start applying shingles to zone one, at the bottom of the cone, and then work your way up to zones two and three.

While you are nailing, have another crew member help hold the shingles down around the curve so they are flush against the surface.

Side overlap of shingles is more noticeable in the upper portions of each cone. Trim shingles at an angle to make the joint parallel to water flow. (Copyright Asphalt Roofing Manufacturers Association, reprinted with permission.)

Because the cone shape tapers from the base to the peak, succeeding courses require less material.

The degree of horizontal offset and varied shingle cutouts will create a random appearance. When using standard three-tab shingles, trim each shingle for proper vertical alignment. A simpler alternative would be to use a randomly applied shingle that doesn’t need to be vertically aligned.

Shingling a cone-shaped roof may be challenging, but with the proper knowledge and execution, you can restore this architectural focal point to its full glory.
