IRE 2019: Education and New Products Take the Spotlight
March 14, 2019
Approximately 10 years ago, the marketing community was declaring conventions and tradeshows a dying industry. However, after attending the 2019 International Roofing Expo (IRE) in Nashville, Tennessee, last month, this notion has not infiltrated the roofing industry. With more than 14,000 attendees and nearly 500 exhibiting companies, the roofing industry certainly supports tradeshows and continues to find value in bringing together like-minded professionals and friendly competitors pitching their products, and selling their services.

The most striking takeaway from the IRE this year was that professional education and new product launches took center stage. As one of many exhibiting/sponsoring companies that promoted education and announced new products, it was evident that the roofing industry continues to support these endeavors. With so much activity on the tradeshow floor and the energy that consumes Music City, it was easy to miss some of these excellent promotions.

This post is part one of two, and will summarize of some of my favorite sessions from CCM's Training & Education Center on the show floor.

Worker Training Programs and NRCA ProCertification™
As the roofing industry faces compelling workforce challenges, it is more important than ever to offer exceptional training and a career path for field workers. Guest speakers from NRCA presented this session that focused on their training and certification programs, and provided guidance on how to attract and retain workers while maximizing productivity—and the bottom line.

Increasing Rooftop Productivity
With a shortage in qualified labor for the roofing industry, increasing productivity is now more important than ever. During this session sponsored by Versico, guests learned to save on labor and increase rooftop productivity by taking advantage of Versico’s deep lineup of labor-saving product options.

Proper Design & Detailing of a Metal Roof
Although not a single-ply presentation, this session -co-sponored by Sherwin-Williams and CCM’s Drexel Metals -was worth checking out if you wanted to Make More with Metal. During this session, important factors such as wind speed and other environmental elements, positive and negative loading, roof slope, and roof height were all discussed. All of these elements require special consideration when planning a metal roof system.

Single-Ply Roofing Adhesives - Seasonal Options
There is a wide variety of adhesive options in the market today: water-based, solvent-based, two-component, and pressurized adhesives; to list a few. The proper adhesive option is sometimes a difficult question to answer, especially when weather conditions become a factor. During this session, best practices were evaluated to promote optimal performance.

How to Save Material Costs and Labor by Using EPS in a Single-Ply System
CCM’s Insulfoam brand sponsored this session, which discussed how to achieve required R-values with fewer insulation layers and less time overall on the roof. Attendees learned how to get the highest R-value per dollar with hybrid EPS and Polyiso insulation systems in a single-ply system to save time and money.

Liquid Applied Roofing: Sustaining Roof Assets
CCM’s Carlisle Roof Foam and Coatings sponsored this presentation that covered tools and systematic approaches for evaluating existing roof systems, understanding application constraints, and keys to successful liquid-applied restoration systems.

Stay tuned for part two in a couple weeks.

Welding TPO and PVC Coated Metal

Welding Versico’s coated metal is quick and easy if you follow a few simple guidelines. Here are some useful tips for your next VersiWeld® TPO or VersiFlex™ PVC Coated Metal installation.  Product facts Description: 24-gauge hot-dipped G90 galvanized steel sheeting with a layer of 35-mil non-reinforced TPO or PVC flashing laminated to one side Size: 4’ by 10’ Packaging: 10 or 25 sheets per pallet Standard colors: TPO – White, Tan, Gray, Bronze, Patina Green, Rock Brown, Terra Cotta, Slate Gray PVC – White, Tan, Gray Markings: The underside of each coated metal sheet is marked with “TPO” or “PVC”; these markings are repeated several times to avoid misidentification Shelf life: None IMPORTANT: TPO and PVC are not interchangeable and will not weld to each other Before you begin It is essential that the material is clean. The flat sheet goes through a few processes at the contractor’s metal shop, including shearing and breaking. When the metal is formed, it picks up dirt and contaminants that can negatively affect its weldability. The most common error associated with hot-air welding coated metal is the lack of proper cleaning. After the coated metal profiles are fastened into place on the roof and before you begin welding, clean with Weathered Membrane Cleaner (for TPO) or PVC and KEE HP Membrane Cleaner (for PVC and KEE HP). Pour the appropriate cleaner from a safety can onto an HP Splice Wipe or other natural fiber rag; then, wipe the metal with the wet cloth to make sure the entire area is clean. If there’s a heavy buildup of dirt, you may need to use a Primer Pad to remove it. When working with cleaners, remember to wear appropriate personal protective equipment, including safety glasses and permeation-resistant gloves that meet ANSI/ISEA 105-2005. Make sure the underside of the membrane being welded to the coated metal is also cleaned. Allow at least 10 to 15 minutes for the solvents in the cleaner to flash off the surfaces you’ll be welding. Heat welder setup When setting up your heat welder, you must consider the thickness of the membrane you’re welding to the coated metal. An 80-mil membrane will require more heat than a 45- or 50-mil membrane. Start the process with the hand welder at the number 7 or 8 setting. Because the 35-mil TPO or PVC film is laminated to the metal, it remains robust during the welding process and will accept more heat without distortion. Welding coated metal to membrane Start the welding process by building an air dam parallel to the rear edge of the metal. This will trap the heat and ensure it isn’t lost under the membrane. Using a hand welder and a 2” neoprene roller, weld the membrane to the coated metal, then roll in a perpendicular motion. Check your welds To check for proper fusion, weld a strip of membrane to a scrap piece of coated metal. Once your weld has cooled, pull the membrane until failure. Proper fusion has occurred if the membrane delaminates from itself, leaving the bottom ply welded to the film, or if the membrane tears when you try to pull it off the coated metal. For more information on securement requirements and instructions on how to address metal end joints, follow detail TPC-1.2.

Quick-Applied Flashing Options for Every Detail

Versico offers three different types of VersiGard® EPDM Quick-Applied (QA) Flashings to tackle the variety of details found on any given roof. All three feature the proven weatherability of EPDM and come with 30-mil of QA seam tape to create a watertight seal. The primary difference among the three is the amount of cure in the rubber, and the process used to manufacture them. QA Uncured EPDM Flashing is used to flash irregularly-shaped objects or details with multiple angle changes. The uncured state of the flashing allows the rubber to be formed and stretched into place without reverting to its original shape, like cured rubber. The flashing formulation is designed to cure on the roof with exposure to heat. Since we need to limit heat exposure in the manufacturing process to keep the product uncured, we require all edges to be lap sealed. This is to keep water from getting between the flashing ply and the tape ply while the material cures on the roof. T-joints, corners, and pockets are all made from uncured flashing; which has a 9-month shelf life. QA Overlayment Strip – often called “semi-cured” flashing – utilizes the same uncured flashing formulation, but is semi-cured with heat during the manufacturing process. The overlayment strip has the dark black look of uncured flashing, but is 70% cured to add tear resistance for stripping in metal edging or end laps. QA Overlayment Strip is packaged without the diamond pattern film as it is removed during the semi-curing process. This gives you an easy way to tell the difference between a roll of QA Uncured Flashing and QA Semi-Cured Flashing. Due to the semi-cured nature of QA Overlayment Strip, it can seal step-offs at splice intersections of 60-mil rubber without the need for T-joint covers. QA Overlayment Strip is better suited to strip-in seams than QA Uncured EPDM Flashing, as you can eliminate the need for lap sealant and T-joints. QA Cured Cover Strip is made with the same 60-mil non-reinforced membrane as our standard sheeting, and is then laminated to 30-mil of QA seam tape. This product is primarily used for stripping-in metal or end-laps, and offers the same finished appearance as the field membrane. Due to the fully-cured nature and thickness of the product, T-joints are required at splice intersections. VersiGard White EPDM Peel & Stick Flashing is available in uncured flashing and cured cover strip options; and is approved for use on both EPDM and TPO roofing systems. VersiGard’s White EPDM Peel & Stick Uncured Flashing has a more aggressive cure package to account for the fact that the white flashing will not gain as much heat naturally on the roof. This translates into a shorter shelf life of 6 months. Keeping your white or black uncured flashings cool during long term storage will help you to maximize its shelf life. Versico has all your flashing needs covered. For more information about pressure-sensitive flashings, please contact your Regional Technical Manager.     Ron Goodman     EPDM Product Manager     Product Marketing     ron.goodman@carlisleccm.com

CAV-GRIP 3V vs. Traditional Bonding Adhesive

With the introduction of Versico’s CAV-GRIP™ 3V Adhesive, it’s faster than ever to install fully adhered TPO and EPDM. CAV-GRIP 3V can be used to adhere standard TPO and EPDM membranes in weather conditions down to 25°F, with a much faster application rate and flash-off time than traditional bonding adhesive. Check out this time trial video for proof, and use the tips below to ensure maximum speed and efficiency. Here are some keys to saving time and getting a the most out of CAV-GRIP 3V: Use larger cylinders and hose splitters: CAV-GRIP 3V comes in two sizes -- 85lb. and 40lb. cylinders. Using 85lb. cylinders allows for more coverage without having to change tanks. By using a hose splitter, two people can spray CAV-GRIP 3V from one tank at the same time, allowing for faster application. Keep cylinders warm in cold weather: As CAV-GRIP 3V cylinders get cold, the coverage rate will be reduced and application will become more difficult. Store cylinders inside or in a hot-box at 70-80°Fbefore use. It is also important not to set cylinders directly on a metal deck, as this will accelerate heat loss. Instead, always set the cylinder on insulation and use a Power Blanket to keep it warm during application. Overlap is key: When applying CAV-GRIP 3V to adhere EPDM or TPO in the field of the roof, very little overlap is required. While spraying, try to overlap 1-2 inches to ensure 100% coverage on the back of the sheet and the substrate. However, when using CAV-GRIP 3V to adhere membranes to walls, it is important to overlap 50% when spraying. Use CAV-GRIP 3V and these tips to save a ton of time and labor on the roof. Time previously used to be spent stirring, rolling, and waiting for adhesive to flash off can now be spent laying more squares of roof to get on to the next job more quickly. For more information on CAV-GRIP 3V, please visit our Labor Saver page or reach out to Adam Burzynski with further questions.     Adam Burzynski     TPO Product Manager     Product Marketing     adam.burzynski@carlisleccm.com
