Galvalume Perimeter Drip Edge Flashing
Perimeter drip edge flashings made of zinc-coated steel are a finial that should be found on every flat roof. With their smooth exterior surface, perimeter edge flashings improve the aesthetics of the walls, with their protruding top edge they perform a role similar to gravel stop flashing, and their gentle offset from the building mass directs water away from areas that may be prone to flooding during rain.
Unlike T-style drip edges, perimeter edge flashings do not work well on roofs covered with asphalt shingles, cedar shakes or slate tiles. It is a solution designed for installation on EPDM, PVC and TPO roofs.
Galvanized Steel Perimeter Edge Flashing Features
The team at Northshore Sheet Metals has refined our perimeter edge flashings to outclass their competition. We believe that the essential function of any drip edge is to effectively direct water away from the roof and protect the fascia from soaking. For this reason, our products do this as well as possible. We achieved this with a perfectly designed shape and a smooth surface that facilitates the flow of water.
The perimeter drip edge flashings we manufacture also protect the edges of the roof from wind and mechanical damage. A properly installed drip edge should extend a little beyond the outline of the roof panels, so there is a good chance that when hit by a branch, only the flashing, which is easy to replace or repair, will be damaged.
Drip edge is also the perfect finish for the roof you are building. Using the highest quality 24 gauge zinc-coated steel sheets, our perimeter edge flashings stand out for their above-average quality and durability. The 0.025” thick galvanized steel provides up to 70 years of trouble-free service. With proper maintenance, perforation of galvalume is probably impossible.
How to Use Galvalume Perimeter Drip Edge Flashings?
First and foremost, we recommend that perimeter edge flashings be installed on cleats solidly attached to structural elements, not to the roof deck or insulation layer.It’s also worth remembering to use a suitably durable adhesive, preferably one that is certified for outdoor use.
Engineers at North Shore Sheet Metals also suggest that cleats be bolted to the wall as solidly as possible – due to their large surface area, the aerodynamic drag generated by perimeter edge flashings is very high, which, in strong winds, can simply pull them from their mounts.
Galvanization is a metal coating process giving roofing panels perfect durability that outclasses standard paints, it also significantly reduces the risk of rusting. However, we do always recommend cleaning metal roofing panels only with a soft brush and water and detergent. This method will be completely sufficient and will remove the vast majority of contaminants, and will not scratch the zinc coating.
