Pop quiz. Should you install a metal roof or asphalt shingles? Asphalt shingle roofs are everywhere. But metal roofs have been in use for almost three thousand years. They have come a long way from the simple, yet functional corrugated or standing seam metal roof design usually associated with barns or sheds. So, which is the best choice for you? To answer this, let’s take a deeper look under the hood, or the roof, as it may be.

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.

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?

Non-penetrating rooftop mounting refers to the ability to mechanically attach a clamp to a standing seam roof by gripping the seam in such a way that there is no penetration to the panel material. The best method for standing seam clamp attachment is via round-point setscrews
Using cup-point setscrews is ill-advised as such a screw point cuts through the paint and protective coating of standing seam panels, causing corrosion and voiding warranties.
In the metal roofing construction industry, mounting ancillary items is often a convenient and necessary aspect of desired performance. Obviously, the best way to maintain the integrity of a metal roof is to allow it to function only as a roof. But various rooftop utilities such as, HVAC, piping, walkways, vents, satellite dishes, snow retention, solar arrays, signage, fall protection, lightning protection, etc. all serve critical purposes and must attach to the roof.

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.

Upon reading the Solar Power World article Metal Roofs are No Problem for Solar Installations, my reaction was, "Well, I suppose that is true—if (and only if) it is done 'the right way.'" There are so many materials, profiles, gauges, metallurgies and corrosion behaviors to consider; not to mention effective waterproofing methods, sealant chemistries, thermal cycling characteristics, weathering behaviors, strength of materials, structural engineering principals and relevant test methods. It is anything but a simple science!
