Storage of Materials During Inclement Weather
April 16, 2019
When storing roofing materials prior to install, it is important to remember most roofing materials are not designed to be stored in cold or inclement weather conditions; especially when ambient temperatures dip below 40°F. Membranes, adhesives, equipment, and contractors will perform differently in colder or inclement weather - so planning and considering how the inclement weather will impact material storage, installation time, and quality is critical.

Membrane: Storing roofing membrane at the job site during warm months is straightforward: keep the rolls off the ground (on pallets), and protect them from moisture by using breathable, waterproof tarpaulins. In inclement weather, temperatures could grow colder - the dew point and temperature come closer together; increasing the potential for condensation and frost forming on materials; and storms/winds become more frequent. Keep roofing materials warm and dry by storing them inside a conditioned space or in a heated job trailer. Keeping materials warm and dry will reduce the risk of moisture being introduced into the roof system during construction, and minimize the possibility of deficiencies in the completed roof system. In addition, material rolls will become more rigid as they get colder, requiring additional time to kick out and relax the membrane before installing. In wet or windy conditions, make sure the roof membrane rolls are covered with a breathable-waterproof tarp and that the tarpaulins are secured to prevent wind damage and/or displacement such as with a pallet or bands. Please note that flashings must be heated prior to application, regardless of the season. When these products are heated until warm to the touch, they will be much easier to install, particularly when flashing corners and irregular shapes.

Adhesives/Pressure-Sensitive Products: When dealing with membrane adhesives, there are generally two main categories to consider: solvent-based and waterborne adhesives. Recently, the use of waterborne adhesives has been growing steadily because of low-odor and VOC code requirements. Both types of adhesives have similar manufacturer recommendations for storage temperature, typically between 60° and 80°F. Adhesives, primers, or pressure-sensitive products can be stored at temperatures below 60°F, but must be restored to between 60°-80°F prior to application for best results. When ambient temperatures are expected to fall below 40°F for an extended period, a heated enclosure or hot box is strongly recommended for jobsite storage. This applies to pressure-sensitive products as well.

Insulation: Polyisocyanurate or polystyrene insulation is typically shipped protected by a plastic wrap, plastic bag, or both. This factory packaging is intended for handling the polyisocyanurate in the manufacturing plant and during transit; it should not be relied upon as protection at jobsites or other outdoor storage locations, unless otherwise specified by the manufacturer.

To ensure insulation is properly protected in inclement weather, follow these steps:
  1. Store bundles flat and upright with the bottom of the bundles elevated (2” or more) above a finished surface -preferably gravel, pavement, or concrete - rather than on dirt or grass.
  2. Slit the bundle packaging vertically down the center of the two short sides to prevent moisture accumulation within the package.
  3. Completely cover the bundle with a waterproof tarp and secure to prevent wind damage and/or displacement, such as a pallet.
Following these steps as outlined above will increase the success and longevity of the roofing materials. For more information about storage of materials in inclement weather, please contact John Greko.

Achieve the Look of a Metal Roof Using New TPO Colors and Contour Rib

The Sure-Weld® TPO Contour Rib profile is a great way to achieve a standing seam metal roof look on sloped roofs or mansards. Sure-Weld TPO membrane and the contour rib profile are now stocked with no minimum order quantities in five special colors in addition to the standard white, gray, and tan options. This makes it even easier to satisfy a building owner’s desire for an aesthetically pleasing standing seam look using TPO. When using special color TPO and contour rib, an owner will be judging the finished roof on its looks, in addition to its performance. It’s important to ensure proper spacing and alignment, and consider where membrane splices will fall when installing the contour rib profile. Here are some easy tips to follow on your next contour rib profile job: “Measure twice, cut once”: Similar to the old carpenter’s saying, check your measurements before you start the job. Prior to installing any contour ribs, measure the spacing for the ribs on the roof to ensure they are spaced properly. If possible, try to align the edge of a contour rib with a splice in the membrane to hide seams. Use a jig or pan to make spacing easy: Once the spacing has been determined, lay out a few ribs on the ground and position the automatic welder as if the rib is being welded. Then, measure the space between the edge of the welder and the next rib. This dimension can be used to fabricate a metal pan to ensure proper alignment and spacing of the ribs. The first rib is critical: Always chalk a line to position and install the first rib. Align the edge of the rib with the chalk line and tack-weld it every 6” to ensure it is perfectly straight and stays in place. If done properly, the first rib can act as a guide to align the next rib using the metal spacing pan. Ensure that after tack welding the first rib for positioning purposes, it is fully welded for permanent installation. Use heat to hold contour rib pieces together: To reduce separation of connected contour rib pieces during the welding process, use a hand welder to heat the end of one of the contour ribs after inserting the connector pin, and push the two ends together. This will help eliminate small gaps between contour rib pieces. Sure-Weld TPO special colors and contour ribs can give a building the look of a metal roof, with the fast installation and proven performance of TPO. Refer to the Contour Rib Installation Guide for more great tips to make sure your next Special Color Contour Rib installation is a success.     Adam Burzynski     TPO Product Manager     Product Marketing     [email protected]

Solve Unique Problems with PVC Pressure-Sensitive Cover Strip

In the past, metal edge options on a PVC roof were extremely limited. Applicators had a choice of white, gray, or tan coated metal unless they were willing to step up to an expensive two-piece metal edge system. This is no longer the case. With the introduction of Carlisle’s Sure-Flex™ Pressure-Sensitive (PS) PVC Cover Strip, the building owner or architect can now choose any color Kynar-coated metal that they prefer. The PVC PS Cover Strip installation process looks like this: Apply the PVC Step 1 Activator to the membrane surface with a roller. The Activator is the first of two primer steps that prepare the membrane to accept the pressure-sensitive cover strip. After the Activator has completely flashed-off, the Step 2 Primer can be applied. Ensure that the primer is covering both the Activator, and the metal. The third and final step is to install the pressure-sensitive cover strip once the primer has flashed-off. Unroll a few feet, pull the release liner, and place the cover strip onto the previously-primed surface. Adhere using a hand roller. Use of the Sure-Flex PVC Pressure-Sensitive Cover Strip will save money, labor, and time on the roof. Utilize this problem-solving product on a current PVC roofing job, and experience what applicators have been calling a “game changer.” To learn more, view the installation guide or visit the Problem Solver page.
