Word of the Week: What is a Trapezoidal Rib Roof Profile?

Posted by Kimberly Reichert on Apr 29, 2019 12:03:47 PM

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.

Word of the Week: What are the Parts of a Metal Roof?

Posted by Kimberly Reichert on Apr 4, 2019 11:18:59 AM

WORD OF THE WEEK: Dormer

PRONUNCIATION: \ ˈdȯr-mər

PART OF SPEECH: NOUN

SENTENCE: // A dormer is a structural projection from the main roof. It is usually gabled and typically has a window. The word dormer refers to the whole projection, not just the window. 

When referring specifically to the window itself, it would be called a “dormer window”. It comes from the Latin word dormitorium, which means “sleeping room”.

But what about everything else that makes up a metal roof? From flashing, ridges, to valleys and eaves. Where are all these on a roof and what is their purpose? Read on as we deconstruct the rest of the metal roof.

Metal Roof vs Asphalt Shingles Comparison: 9 Tips for Choosing - 2019

Posted by Kimberly Reichert on Mar 18, 2019 11:59:16 AM

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.

Word of the Week: What is UL Listed?

Posted by Kimberly Reichert on Feb 21, 2019 8:33:31 AM

 

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.

Word of the Week: What is Non-Penetrating Rooftop Mounting?

Posted by Kimberly Reichert on Feb 6, 2019 9:16:26 AM

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.

Word of the Week: What is a Rooftop Avalanche? [video]

Posted by Kimberly Reichert on Jan 30, 2019 11:17:24 AM

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.

Standing Seam vs Exposed Fastener Metal Roofs: 2019 Comparison

Posted by Kimberly Reichert on Dec 19, 2018 12:28:39 PM

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.

Get that Project Off the Ground: Why Use S-5!’s Snow Guard Calculator?

This is a two-part series featuring the S-5! Snow Guard Calculator. Step 1 covers exactly why it is imperative to engineer your snow guard system and to utilize our online calculator to get the job done. Below, we'll walk you through exactly the calculator's purpose. Then in Step 2, we'll explain exactly how to logon and get started!

Your roof has been developing a perfectly rounded overhang of migrating snow right over your door. It glistens beautifully in the sun and seems to defy gravity as it gets bigger and bigger. But all you can think of is when it is going to fall. That is a smart premonition; because it will at some point. Snow avalanches can be unpredictable and catastrophic events. And the snow will fall wherever and whenever it wants to – on you, a loved one, your car or sidewalk.
