Roof-to-wall flashing, also called sidewall or headwall flashing, seals the edge of the roof. Providing an aesthetically pleasing connection between the rooftop and the wall, it perfectly seals the interface between the two planes. As a result, water does not enter the building, which could develop mold. Galvalume roof-to-wall flashings are typically used at the junction of roofs and chimneys or other vertical walls extending beyond the outline of the roof slope. To maximize the tightness of the joints, we recommend installation as in the attached diagram. We also encourage you to use adequate caulking – Sikaflex or Quad caulking will give you a peace of mind.
Sidewall flashings in the offer of North Shore Sheet Metals are distinguished by their excellent workmanship, above-average durability and attractive price. This is made possible by scale – each year, our company produces hundreds of thousands of lineal feet of flashings, gutters and other sheet metal components. Being a large manufacturer of steel and aluminum products, we can compete on price, and thanks to the use of modern machinery, we also stand out with phenomenal quality.
Headwall flashings manufactured in our company are offered in two variants – with and without kick. In practice, by far the more common choice is sidewall flashings, which are used to seal roofs made by GAF roofing contractor Glenview as well as other contractors installing asphalt shingles and cedar shakes. For roof-to-wall flashings with kick, roofs made of steel or aluminum are used.
For even greater durability and aesthetics, our roof-to-wall flashings are coated with a thick aluminum-zinc alloy coating that offers superior corrosion protection for many years. The process of coating makes our roof-to-wall flashing protected from direct sunlight, water and salt.
The thickness of the sheet metal we use is also crucial. Engineers employed by North Shore Sheet Metals have spent hundreds of hours selecting the ideal galvanized steel sheet thickness that offers the perfect compromise between weight, bending resistance, brittleness and price. As a result, by choosing roof-to-wall flashings made from 0.025” (24 Ga) galvalume-coated steel you are assured that your customer will enjoy many years of trouble-free use of their roof, no matter where they live.
Compared to flashings sold by the most recognizable vendors, our products are up to 35% more rigid and offer up to 70% longer lifespan. 99.4% of our flashings last at least 30 years in a climate of Chicago.
Galvalume is a special coating, designed specifically for steel products such as flashings and gutters. Consisting of 55% of aluminum, 43.4% zinc and 1.6% silicone, this alloy works as a superior barrier, protecting the 24 Gauge steel against acid rain, salt, water and oxidation. It results with even 4 times longer lifespan when compared to standard galvanized steel.
Choice of Galvalume is a real investment – it drastically reduces the risk warranty claims due to the leaks forming in the most vulnerable roof areas. Buying a solid coated flashing makes it virtually impossible for water to penetrate it, while standard galvanized steel or PVC-coated steel may simply fail.
Our Galvalume roof-to-wall flashings comply with ASTM A792 Standard and is suitable for exterior use even in harsh climate conditions.
This product is compatible with virtually every roofing material. Galvalume is non-reacting cover, which means that it’s safe to use it with materials such as cedar shakes, asphalt shingles, synthetic shakes and tiles, natural slate, Galvalume and aluminum roofing.
