Making the Choice Between Prefabricated and Shop-fabricated Metal

When it comes to choosing a fascia or coping, the options for colors, finishes, and profiles are virtually endless. Most times, the color and finish will be dictated by the building owner or designer. Roofers and general contractors, on the other hand, often have much more influence over which profile is used and how it’s sourced. This post breaks down the benefits of prefabricated edge metal (such as Carlisle SecurEdge products) as well as the advantages of shop-fabricated edge metal (made in-house by the roofing contractor or outsourced to a local sheet metal shop). Prefabricated edge metal has a lot to offer, from enhanced performance and code compliance to labor-saving benefits. Below are a few of the advantages of using prefabricated edge metal. Testing and code compliance: All Carlisle SecurEdge products are tested to ANSI/SPRI ES-1 standards as required by International Building Code. ES-1 testing has been mandatory for all low-slope roofs since IBC-2003 and using prefabricated SecurEdge ensures that code requirements can be met. The majority of SecurEdge coping and fascia profiles offered by Carlisle are also approved for use on Factory Mutual-insured buildings or where FM-approved edge flashings are required. Convenience: Using prefabricated SecurEdge products allows contractors to order edge metal and have it shipped directly to the jobsite, with many products available to ship within days. No sheet metal shop is required. On the flip side, roofing contractors who have shops with skilled sheet metal workers can use those resources to work on more complex and profitable sheet metal work, rather than fabricating basic coping and fascia designs. Labor Savings: Unlike traditional gravel stop and drip edge, many SecurEdge profiles have a snap-on design and do not need to be stripped in. This saves considerable labor on the roof and eliminates the need to use primer and cover strip (as is typical with a drip edge or gravel stop). Warranty: All SecurEdge products are covered under the Edge-to-Edge Total Roof System Warranty, offering the building owner protection backed by Carlisle. While prefabricated edge metal offers many advantages over shop-fabricated edge metal, local fabrication has its own benefits, and shop-fabricated metal is still covered in some Carlisle warranted roof systems. Here are a few reasons why shop-fabricated edge metal might be a good fit for a project. Flexibility: While SecurEdge products can be customized, it’s often easier to create complex custom parts locally where the sheet metal fabricator can see what is needed, measure, and fabricate the part. Speed: Many SecurEdge profiles can be shipped in as little as one day; however, if you need something immediately, there’s no substitute for a local sheet metal shop that can fabricate something for installation the same day. Warranty: While SecurEdge will almost always meet warranty requirements, shop-fabricated metal using Carlisle metal flat sheets can also be included in many warranted roof systems for up to 20 years.

TPO and PVC Welding Guidelines

Cold welds are a major concern for any thermoplastic roofing installer. But following a few basic guidelines can go a long way toward ensuring good, long-lasting welds on TPO, PVC, and KEE HP membranes. In this post, we’ll discuss a few best practices that reduce the chances of cold welds and help ensure the watertight integrity of TPO, PVC, and KEE HP single-ply roof systems. 1. Appropriate Equipment Use proper power sources or commercial-grade generators. Generators should be rated for 3,000 watts for two hand welders, or 6,500 watts for one auto-welder. Proper extension cords are critical. For auto-welders, use a 10-gauge wire with a maximum length of 100 feet; for hand welders, use a 12-gauge wire with a maximum length of 100 feet. Welders should be in good shape, with clean air screens and a clean nozzle. 2. Proper Temperatures The following are starting guidelines for temperature, speed, and airflow. Settings may vary depending on membrane thickness (45-, 50-, 60-, or 80-mil). Leister Varimat Temp Speed Airflow TPO 1004°F 12.5 ft/min 100% PVC & KEE HP 1094°F 8.5 ft/min 100% ​ Leister V2   Temp  Speed Airflow TPO 986°F 18 ft/min 90% PVC & KEE HP 1094°F 10.4 ft/min 75% ​ BAK LarOn Temp Speed  Airflow  TPO 1004°F 12.5 ft/min 100% PVC & KEE HP 1094°F 8.5 ft/min 100% 3. Critical Welding Steps Keep in mind that ambient temperatures will affect welding temperatures and speeds, as will welding in the sun versus welding in the shade. Certain substrates can hold heat in the membrane (polyiso insulation), while others can rob the heat from the membrane (concrete). When hand welding, immediately roll across the hot seam at a 45° angle with a 2” silicone roller. This helps to ensure the top membrane is adequately pressed into the bottom membrane. When welding across a step-off, be sure to crease the top membrane into the step-off with a 2” silicone roller immediately after welding. This will help prevent a water channel from forming in the weld. It’s important to perform test welds several times each day because of changing ambient and membrane temperatures. Simply cut a 1”-wide strip across the weld and peel to inspect the weld area. Remember to probe all seams at the end of each work day. 4. Cleaning and Maintenance Always clean aged or dirty membrane before welding. On PVC or KEE HP, use PVC and KEE HP Membrane Cleaner; on TPO, use Weathered Membrane Cleaner. Clean all residue from the weld area and allow it to dry before welding. Maintain your equipment before, during, and after welding. Regularly inspect the silicone pressure wheels on your auto-welder and hand roller to make sure they’re not affecting the integrity of the membrane while welding or rolling. Clean the char off the heat gun nozzle using a brass wire brush and keep the intake free of debris to allow maximum airflow. On the auto-welder, adjust the nozzle to eliminate heel drag. Following these helpful hints will ensure a better installation with fewer cold welds.

Addressing Common Mistakes with Two-Component Low-Rise Adhesives

Two-component low-rise urethane adhesives have become increasingly popular since their introduction into the single-ply roofing industry over 30 years ago. Since 2015, the two-component low-rise urethane adhesive market has significantly expanded due to the introduction of new low-pressure dispensing equipment. While low-rise urethane adhesives provide several advantages when designing a roof to withstand extreme weather events, there are common mistakes that can affect the application of the product. Below are common mistakes that can occur during two-component urethane adhesive applications: Gaps between the deck and wall/penetration that are not sealed: Unsealed gaps allow humid air to enter the roofing assembly and condensate on the deck, weakening the insulation facer. A physical air block using foam or a backer rod in addition to VapAir 725TR or Pressure-Sensitive Flashing is required. Loose material or moisture on the deck: Dirt, dust, debris, and loose felts will compromise the adhesive bond. After brooming, use a blower to remove any residual contamination. Deck must be dry. Un-weathered asphalt wasn’t primed: Carlisle requires the use of CAV-GRIP™ III or 702 Primer over weathered asphalt when beads are spaced at 4”, 6", or 12" o.c.. Adhesion to un-weathered asphalt is doubled with CAV-GRIP III or 702 Primer, with CAV-GRIP III being the preferred method. Fastening the first layer of insulation is an option. Depressions in the deck not accounted for: Hard insulation boards will bridge depressions or deflections in the deck. These areas should be marked ahead of time so that more adhesive or thicker adhesive can be applied to compensate. Pencil thin beads applied: Proper application and performance requires a minimum ½"-wide wet bead of adhesive that will foam out to around 1-1.5". Bead spacing exceeds specification: Bead spacing has a direct impact on the uplift performance of the assembly. If the spec calls for 6" o.c. and it is applied it at 8" or 9" o.c., the ultimate uplift strength will be reduced. A 4" o.c. spacing requires 12 beads per 4' x 4' board. A 6" o.c. spacing requires 8 beads per 4' x 4' board. A 12" o.c. spacing requires 4 beads per 4' x 4' board (Maximum 4' x 4' insulation boards when adhesive is extruded at 12" o.c. or when boards exceed 4" thickness, or 4' x 8' insulation boards when adhesive is applied in full spray, 4", or 6" beads.). 12" bead spacing used in corners and perimeters: Corners and perimeters experience more wind uplift pressure, which is why Carlisle requires tighter bead spacing in these areas. 12" bead spacing is not acceptable in corners or perimeters. Know the spacing requirements prior to starting the job. Thin application over gravel BUR: A thicker application of adhesive is required over a properly prepared gravel BUR. The foam must rise 3/8" above the remaining gravel, or it won’t touch the board. Not waiting for “string/gel” time: If insulation boards are set prior to the adhesive reaching string- or gel-like consistency, the foam cells collapse back to a liquid and the adhesive loses a significant amount of its holding power. This is very important to note. No weighted roller used, and no relief cuts or constant weight applied: Rigid insulation boards must be forced into the adhesive with a 150-lb. segmented weighted roller. Relief cuts and constant weight are sometimes required to promote a solid bond. Rolling the boards at the 5-minute mark allows adhesive to gain strength. Changing static mixing tips: When the Part-A side and Part-B side of 2-component urethane adhesives are mixed together, it creates a thermal reaction that produces the adhesive. The adhesive in small static mixing tips will begin to solidify after 15-20 seconds, meaning the tips must be changed to avoid off-ratio or clogged guns. Not shaking Dual Tanks: Dual Tanks use a propellant to disperse the adhesive. To activate the propellant, the tanks must be shaken for 30-seconds prior to using. When the tanks are not agitated, the adhesive will not disperse properly, reducing coverage rates or producing off ratio adhesive. Cold or Hot Adhesive: Keeping adhesive at the recommended temperatures is important to ensure proper performance. Adhesives that are too cold or too hot will affect coverage rates and the performance of the adhesive. During winter applications, hot boxes and heated blankets should be used to keep the material between 70-90°F.
