A trapezoidal roof profile has a ribbed trapezoidal-shape pattern across the panel. This means, it is a quadrilateral (or a four-sided shape – see Figure 1) that has just a single pair of parallel sides. Sometimes, trapezoidal roofs are mistakenly referred to as corrugated. This is a misnomer as the corrugated profile has a repeating wavy pattern across its surface.Trapezoidal rib roofs are popular with producers because the shape makes them very material-efficient (a high strength-to weight ratio). This makes for a very cost-effective profile. The shadows of the trapezoidal shapes offer clean lines whether installed vertically, diagonally, or horizontally. They also possess good structural characteristics and can carry design loads well (e.g. for snow and wind uplift). However, it is not considered as premium a profile as standing seam due to its attachment method.
The International Roofing Expo (IRE) recently concluded in Nashville, TN. Now that the busy din of the show has subsided, it is a perfect chance to reflect on the show’s success. What did those who actually went think of the show?
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.

The coming together of S-5! and S-5! Manufacturing is a tale steeped in history. When Rob Haddock and Harry Carner joined forces, the two created a partnership that now designs and manufactures the safest engineered products and has become the most trusted name in the metal construction industry. Here is Part 1 of our 3 Part history of S-5! Manufacturing.
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.

It is a sudden release of snow off a rooftop. Falling snow forms a temperature-sensitive bond to the surface of a metal roof. As that roof is warmed, (through sun or building heat loss), the bond with the snow is broken and a thin film of melt water lubricates the roof. This sudden release from a rooftop can dump many tons of snow below the eaves in a matter of seconds, endangering building elements, landscape, vehicles and pedestrians.
Qualifying Snow Retention Systems for Metal Roofing, from the Metal Construction Association discusses the rooftop avalanche in the following terms:
Metal roofs provide durable, long-term solutions and have been preferred by many for use in challenging northern and alpine climates where snow and its migration on and from the rooftop is a normal occurrence. Such climates can pose unique challenges for any roof. Pitched roofs of a material that has a slippery surface can pose sliding snow and ice hazards below eaves. In many instances, snow retention systems are installed on these roof types in order to reduce the risk of sudden rooftop avalanche and mitigate the hazards present in the discharge areas below the eaves.

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.

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.
