A corrugated panel has a repeating wavy or rippled pattern across its design. It was the first mass-produced metal panel design in the United States. These panels can be used for roofing, siding, decking, and flooring. Corrugated panels are connected by overlapping the sheets, and then securing them in place with exposed fasteners.
Have you been carefully (or not so carefully) monitoring that gravity-defying overhang of migrating snow that sits atop your roof? Glistening beautifully in the sun, it has stayed up there for days; it will surely stay up a bit longer, right? Sorry, no guarantee. Avalanches are unpredictable and catastrophic events. The snow will fall wherever and whenever it wants to – on you, a loved one, your car or sidewalk.
UL, an abbreviation for Underwriters Laboratories, is a testing and approving organization. Founded in 1894, UL performs safety testing on numerous electrical, mechanical, and chemical consumer and commercial products. Its roots began in electrical and fire safety, but UL now serves other industries and tests hazardous substances, water quality, food safety, and more.
You seem to see it everywhere – that red, black, or white circle with the capital “U” and “L” letters inside. It shows up on various products in our homes and workplaces. You rightly assume that it is important: When something has the UL stamp, it means it has been properly designed and engineered for its specific use. A UL listed mark on a product demonstrates it has been vigorously tested to meet safety specifications determined from the potential and probable hazards of the product. It means the product can be depended on to perform its purpose when needed the most.
It’s time! IRE – the International Roofing Expo has started in Nashville, TN. It officially runs February 11-13 in Music City Center. The exhibit hall in the Center is located in downtown Nashville – incredible roofing products and within walking distance to restaurants and local music venues. What could be better?
Photovoltaics (PV) is the process of converting light into electricity. PV technology converts sunlight (otherwise known as solar radiation) into direct current electricity. This process uses semiconductors, (the most common semiconductor material being crystalline silicon), so when the sun hits the PV, the electrons are released and form an electric current. Photovoltaic technology is commonly attached to a panel; and these solar panels are connected to one another and mounted onto a frame. This PV assembly is called a module and you can wire these modules together into an array. Rays of sunlight (photons) are absorbed by the solar panels. This power then gets converted into Alternating Current (AC) to be used in the house - or sold back to the centralized city grid.
Snow retention helps preserve your metal roof and allows snow drifts and snow melt to exit the roof in a more controlled manner (i.e. in small amounts, evaporation or melt water), avoiding the potential calamity of the rooftop avalanche.
According to the Metal Construction Association's technical document Qualifying Snow Retention Systems for Metal Roofing, a snow retention system, also known as a snow guard system, is a series of unitized snow-guard devices or continuous assemblies installed for the purpose of retaining snow on a roof and allow the snow to evacuate slowly via thaw and sublimation rather than suddenly and unexpectedly via rooftop avalanche.
A metal roof is a metal roof, right? WRONG. Standing seam and exposed fastener roofs may both be metal and may even serve similar purposes, but the two styles are very different indeed.
With our roof pitch snow guard calculator, once you enter a few key points of data, our system will quickly calculate the exact number of guards required and the recommended snow guard spacing for your engineered application.
The calculator saves you time and money in the planning process. There is also an option to get a low-cost certified engineer stamp on your calculations. Read part one on why to use a snow guard calculator here.
Our two-part series is on the S-5! Snow Guard Calculator. Step 1 covers exactly why it is so important to engineer your snow guard system. In Step 2, we'll explain how to log on and get started with your calculation!
Snow retention systems go by many names in the industry. Roof snow fences, snow rails, snow stops, snow stopper, snow guards, snow clips, snow bar, and more. Regardless of the phrase, the intended purpose is the same: to reduce the risks associated with rooftop avalanches. By holding back the snow and encouraging it to leave the roof slowly through small amounts or melting, damage to walls and foundations can be reduced.
This is part one of a two-part series on qualifying snow retention systems.
There is a new (and much needed) document recently published by the Metal Construction Association (MCA): Qualifying Snow Retention Systems for Metal Roofing. This new industry consensus document is perhaps the most valuable tool in your toolbox if you are involved with any aspect of snow guards for any metal roof application.
In places where it frequently snows a lot and even in places where it doesn’t, metal is a favored material in protecting a house or other structure. On the surface, snow might appear to be rather innocuous, as it gently falls from the sky like the ending scene in the movie, White Christmas. But what the movie doesn’t show, is all through the night and much of the morning (if not longer) the light fluffy stuff piles deeper and deeper on top of the roof, incrementally increasing its own weight. Then, when the sun comes out, an avalanche of snow tumbles down onto unsuspecting persons, vehicles and landscapes below.
