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.

Word of the Week: What is a Snow Guard or Snow Retention?

Posted by Kimberly Reichert on Jan 16, 2019 11:47:54 AM

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.

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.

What’s on Your Metal Roof? Components of a Snow Guard System

Posted by Kimberly Reichert on Nov 26, 2018 1:06:13 PM

This is Part Two of a two-part series on qualifying snow retention systems.

Recap of How Snow Retention Works

In Part 1 of What’s on Your Roof? we discussed how, unfortunately, there aren’t any snow guard police out there patrolling the industry. This creates a two-fold problem: One, that you can’t count on there being building inspectors to check a go-to-market system for structural adequacy; and two, architects and installers of these systems can potentially be sued for personal and property damage from faulty snow retention systems they specify or install.

But the light at the end of the tunnel comes in the form of the recently published Qualifying Snow Retention Systems by the MCA (Metal Construction Association). This technical guide bridges the gap between the free-for-all snow guard market and building owners, installers, and architects, who demand knowledge, strength, and a well-engineered system. So, what exactly constitutes a well-engineered system?

What Type of Snow Guard is On Your Metal Roof? Choose The Right Way!

Posted by Kimberly Reichert on Nov 8, 2018 3:58:52 PM

At S-5!, we don’t recommend installing adhesive-mounted snow guards on metal roofs. From both an economic and design perspective, glued on plastic snow guards typically have low holding strength and are unable to handle harsh weather-related elements. The bond weakens over time and when it fails, the guard can rip away paint and protective roof coatings, potentially leading to corrosion.

There Aren't Any Snow Guard Police: What's On Your Metal Roof?

Posted by Kimberly Reichert on Nov 6, 2018 2:13:43 PM

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.

Snow Retention: Reduce the Risk of Rooftop Avalanche

Posted by Kimberly Reichert on Oct 26, 2018 10:30:18 AM

Our new SlideShare offers the best ways to mount snow retention. 

When a snow avalanche falls off of a rooftop, it can damage anything in its path! This sudden release of snow can be dramatic—dumping tons of snow in mere seconds. Falling snow forms a temperature-sensitive bond to the surface of a metal roof. Then, when that roof is warmed, whether from the sun or from building heat loss, the bond between the snow bank and roof is broken and a thin film of melt water serves to lubricate the slide.

 

A several-ton blanket of snow suddenly sliding off the roof can have dramatic results on anything in its path—gutters, the roof itself, landscape, vehicles and even people. Once it is piled up down below, that same snow bank can continue to cause additional troubles (e.g. repeated snow removal; direct damage to building walls; indirect damage caused by funneling melt water into, rather than away from the walls and foundations, etc.).

 

The Reason for Roof Snow Guards

This is what makes snow retention devices desirable: They keep snow in its place allowing it to leave the roof slowly, either in small amounts, evaporation or as melt water, avoiding the potential calamity of the avalanche.

What is the Best Way to Mount Snow Retention to a Metal Roof?

Posted by Jesse Winternitz on Oct 5, 2018 2:11:17 PM

 

Clamp Mounted vs Structure Attachment vs Stick-On Snow Retention Solutions

 

Metal roofs are a smart decision. But with metal roofs, you must consider the risk of roof top avalanches. A quality snow retention system will help you maintain your roof, avoid personal and property damage, and efficiently and safely allow snow to melt off your structure. But there are a number of methods to mount snow guard systems. What is the best way?
