Prevailing wind and metal roofing question

[Leterbuck1980]

I'm having a 40x60x16 shop being built and the other day the contractor and I had a discussion to install the metal roofing so they started away from the prevailing wind and worked towards it. At our place the wind can really blow at times from the south, so we both agreed the best idea is to install starting from the north and work towards the south, so the seams aren't exposed to high winds, rain, snow, etc. They got the roof on yesterday while we were out and about, got home to see that they had a couple pieces left to install and had installed all of it backwards from what we had talked about, thus leaving all the seams vulnerable. I'm not happy about this, the contractor seems to think it is fine and is trying to tell me that the building has a warranty. I asked if the warranty includes the property inside once its finished off and it then leaks because of roof failure due to high wind, no response. Am I over thinking this? The issue is they would have to eat all the roofing and labor, which I am sure he already knows. I'm gonna be at this place for a long, long time not to mention paying a pretty penny for the shop and the years it took to save all that money to pay for my dream shop. I still have about 15% left to pay after completion.

What would you do?

When I erected commercial metal buildings with similar side-laps, there was no specified direction to lap roof sheets. All end and side-laps had sealer applied before lapping the sheets. Wall sheets and trim were lapped so the seams were less noticeable from where the erector thought the owner and occupants would be looking at the wall. None of this was called out on the blueprints.
But maybe what really is the issue is did he do what you all agreed on.
If installed correctly, you’ve got a good roof.
You could have gone with a standing seam at probably much greater cost.

You're in Oregon, you'll be fine. It's not like you get hurricanes up there. I doubt anyone else took that into consideration when building their building.

The Gorge area can get very windy. You two came up with a plan and then they didn't follow through with it......

Eastern oregon, and live near the mountains, it was blowing 60 mph the other night. The wind was making the felt on the window jams in the bedroom whistle so loud both the wife and I woke up. Once the rain started in, the whistling stopped but it was sounded like someone throwing rocks at the windows.

Is this something that is usually taken into consideration or just something you wanted? I would just leave it now. You'll have a bunch of screw holes in the metal and bent panels if they take it all off and flip it around. If they had the whole building made in a days work I would have taken the day off. I almost always take the day off on something like this if I know I'll have to look at whatever they screwed up for the next 30 years.

Exactly, I guess my question is how to proceed from here. This isn't the first thing they have done. It started with not showing up as scheduled. One time I get it, second because of covid, understandable, 3rd time I'm frustrated but accept it, 4th time I'm a little pissed and voice my frustration to the contractor....then the day they were supposed to start, they get 30 min from my place, forget an attachment for the skid steer 3 hrs away and have to turn back and get it, showing up to the site at 2 pm and not getting the posts set that day, not to mention braced properly and the wind blew over 3 of the 6 posts they got set that night.

The contractor brought it up to me, and I replied, that a great call, let's make sure to install it this way.

My wife is from this area, where I used to lived not so much. The first things all our friends and family said to us when we bought this property was that the wind can really blow at times. The neighbor said it took him a while to get in the hang of putting things outside away or he would be picking it up in the wheat field 1/2 mile down the road. I haven't lived here that long, but the short time I have been here, people's descriptions are spot on and where they all said the prevailing wind came from is the direction it blows 90-95% of the time.

The boss probably wasn't their to relay the message to the workers.

They would definitely be paying for new metal, what the hell am I paying top dollar for to have a building installed if I need to be the general and babysit the crew? This is the whole reason I hired this company. Also, ill mention this isn't a fly by night operation, they are one of the largest if not the largest shop builder in the western states.

No he wasn't. When I called the crew lead, he said he told them, only because I can speak Spanish, did the crew on site tell me that he never told them that, but of course they would say that, they are the ones in hot water for installing backwards. At the end of the day its not my responsibility to babysit these guys. We have a newborn that is enough work.

What does the manufacture say about installation. Some specify lapping and prevailing wind direction. This may affect your warranty if installed incorrectly. I would contact them and ask. If they are on your side your issue will be much easier to solve.

Thanks for the heads up on that, good idea.

Hold the 15% until the entire roof is replaced and your happy with the work.

Let’s not assume that there’s anything wrong with the way they did it. Wind blowing across a roof generally wants to **** the sheets up off of the building. The industry has been using this kind of laps for a long time. We’re assuming that, for some reason, these seams just can’t stand up to Oregon winds.

I've put on a lot of multi-rib. Every job I did was for a City so inspectors and engineers were everywhere. Never once did they talk about which way to lap the panels. I also had to pay for Special Inspections due to the bolts used.

Send them home and tell them you were ready, but they are not, come back when ready, tools and ready to go to work.
And always with a BIG smile, cause you are costing them $$$, be YOUR own foreman........... with reason.

You absolutely cannot trust these folks, even from the get go, and for sure with the problem discovered>

Be vigilante, trust but verify. It is the golden rule you got the gold you make the rules.

The ideal way to put them down is the way you specified.

If you want something done a certain way you need to be there to supervise - or better yet, do it yourself so you can look in the mirror for someone to blame. Otherwise trust the pros - I would hope they have more experience building in your area than you do.

If they screwed it down properly you shouldn't have any issues.

Good luck having them redo it as some of these other folks are suggesting.

I am also building a 40x60x16 in Oregon right now. My engineering specified to face laps away from prevailing winds. I'm in Central OR but spent a couple years in Pendleton and it can really blow up there. You could put additional screws in top of the overlapping rib. My plans specified these additional screws in the one end wall that has a big door to act as a shear wall.

prevailing wind is one thing, but the winds are not only from that direction...think about that.

Is 90% + of the time prevailing enough to be concerned?

Four months ago we had a derecho storm come through here from the west.
A fellow two miles west of us had a large building put up three years ago for his business on the bottom and apartment on the top .... about 50 wide by forty deep. All metal roof with the gables on the north - south sides ( 50 foot sides ). I lost many large branches from locust trees.
He lost his roof from the "EAST" side of the building.
All to say .... Mother Nature can be a ***** .... unpredictable.

On both of my metal buildings on our property we absolutely took this into consideration . I would not it accept it . If they Pre drilled the holes properly it shouldn’t be a big deal to re install it correctly .

They did pre-drill the holes, would they get reamed out removing and reinstalling? Thus causing further leaks.....thats my worry

Update now that this is settled. The contractor had stated they would not do anything further and offered a 5 year warranty on the roof for putting it on differently than what was agreed upon. This didn't sit well with me as I plan to be here 30 plus years. In Oregon we have the ability to contact the contractors board and file a claim. The process goes, send a certified letter, wait 30 days, have a state appointed mediator come out to try and resolve the issue with both parties and then if no solution is agreed upon it goes to court. I only got as far as the certified letter and the owner of this large company called to discuss the solution. He clearly stated the roof is fine and he would warranty it but not replace. After thinking it over and talking to my lawyer, we both agreed that a 40 year warranty would suffice. I didn't do the ask for more, get what you want after they talk you down. I simply said this is what I feel is fair and reasonable, 40 year warranty, and if that doesn't work for you then the lawyers can handle it from here. He agreed that it was fair and so I am waiting for the paperwork to sign to make this all legal. It still bugs me that the roof is on backwards, but this gives me some more security in the long run. I guess the old saying is true, the squeaky wheel gets the grease.

The metal that I just installed from Central States Manufacturing has in their install instructions to place overlapping seams to run with prevailing winds.

 

[SARG]

And hopefully they won't go out of business.

 

[Leterbuck1980]

Well, I'm hoping they don't, as they are the largest builder in the 9 western states. They have built over 12,000 buildings is what I've been told. They also invented the perma column, which I used in this shop.

Understood.
Over a decade ago there was a large outfit in the Northeast that was competition for Morton Buildings. I researched them because they wanted to buy a field from me for a facility. They had several other locations ......... but they never returned with a solid offer because they went belly up. Here today gone tomorrow just like all the chain stores that have disappeared.
