Metal Roof Weather Testing (Wind Uplift and Water Penetration)

[@ChristianMasseyAU]

Would have loved to see what the failure pressure was and what kind of sustained wind-speed might generate similar forces in real-world environments. Really high quality video here guys. I'll definitely be checking out your channel.

Thanks for the suggestion, I'll keep that in mind for a future video. I appreciate the support! Have a good one! -Thad

Christian! Here is that video you suggested about UL 90 and wind speeds: bit.ly/UL-90-And-Wind-Speeds Thanks for the support! -Thad

I have tomando and common Windsor from 60-130 km everything winter here what do you recommend, I'm located in Southern Chile

What does the UL90 translate to in terms of wind speed?

[@TheMetalRoofingChannel]

Hello! We just released a Q&A answering your question. Check it out here: bit.ly/UL-90-And-Wind-Speeds Thanks for the comment! -Thad

Very good video. Deserves more views. It would have been cool to see some bad vs good designs. For example if a clip system had a high rating than a screw/nail flange system.

[@TheMetalRoofingChannel]

Adam, thanks for the kind words, and I like that idea of comparing systems! I agree on the views as well, so always feel free to share 😉 Have a good one! -Thad

I can get up to 35 mph up on a hill in VA and during a storm I can get from 50 to 60 mph .I want to do my carport roof in metal because I am tired of the shingles being blown off the 1 side that gets the wind when storms come in

[@joepatrick5678]

Great video. I would like to see how wind uplift and water penetration relate to real life examples. Say this wind uplift would withstand this type storm and etc.

Hello Joe! Here is our new Q&A about how wind uplifts relate to wind speed: bit.ly/UL-90-And-Wind-Speeds Thanks for the suggestion! -Thad

[@garudastan]

does psi equate to a relative wind speed?

[@TheMetalRoofingChannel]

No, PSF and designations like UL 90 do not directly equate to wind speed. The required wind speed can be calculated from the engineering numbers depending on your specific building's features and location. Here's a video that covers how: bit.ly/UL-90-wind-speed-video -Thad

Clip systems are much more expensive then screw/nail strip system....which system will withstand higher wind speeds??....Need to know information....this is the testing needed

[@TheMetalRoofingChannel]

Hello, I replied to one of your others comments with these thoughts: It is our opinion that in high wind zones, a clip system would be preferred over a nail flange system That being said, certain clip systems definitely perform better than others so it is important to know what you are getting and to not assume that a system will be ok just because it has a clip. With a nail flange system you are counting on the head of the fastener to secure the panel down and while the fastener may stay attached in the substrate, the metal slot may rip or pull away from the fastener. This is especially dependent on the metal gauge the nail flange panel is made of . With a clip system you will usually have a minimum of two fasteners per clip and quite often the clip is made from a much thicker gauge than the panel itself. The fastener in a clip goes through a hole designed for that size fastener in lieu of a slot where there is more play. The clip engages over the male leg of the panel creating a strong connection and these clips can be spaced as close or as far apart as needed to meet the requirements for different areas. In a nail flange system, you are limited to the minimum slot spacing. Furthermore, there is less chance of installing the fastener incorrectly in a clip system (i.e. to tight or loose) and clip systems accommodate thermal movement much better. Lastly, you will see some nail flange systems being glued in the panel seams. Doing this allows these panels to achieve some very high uplift pressures because the panel is literally glued together; this is a fairly new approach. While these panels perform well in testing, there is no long term data that we know of showing the performance 10, 20, 30 years down the road. Since metal is a long term product we prefer to use traditional methods of roof attachments within our systems. Hope this helps! -Thad

@@TheMetalRoofingChannel ..ok, thanks....good explanation....its been frustrating dealing with roofers, they don't seem to want to answer the clip/nail strip...question.....and the price difference is substantial.....They deal with Gulf Coast systems here in south/central Florida.....

[@TheMetalRoofingChannel]

I understand, well hopefully you can use some of this knowledge to help you out in your project. If there's anything else I can help you with, let me know! Thanks! -Thad

What seam time is best for hurricane resistance!
