First a Garage

[denmansoft]

No, I would like to get something like it that will work with a raised ridge cap. What I made up is too heavy for much manuevering without damaging the metal panels or ridge cap.
The brits have some nice looking ones from aluminum.

Friday morning, Time to put the metal roof panels on.
Sunrise on a clear morning is worth getting up for!


We put on the eave fascia and flashing and then got started on the main panels. Here is where we got on day One! Cutting and fitting around the dormers is a lot of work!.

Saturday morning I spent a bit more time enjoying the sunrise before getting back on the roof. This time of year the sun comes up over the south tip of Hornby Island.

It can give a real nice display !

We frequently get these large jellyfish washed up on the beach. The red part is about 12" across. Around here the darker the color the more sting you can get from these guys. You wouldn't want to swim into this guy!

A small group of ducks starting their day paddling in the shallows.

The sunrise is even bouncing off the sky to the northwest.

Saturday's roofing got most of the north side done.


And part of the south side.


I had a couple of local young men helping. They mainly showed me how slow I am crawling around on the roof. Its the arthritis, not my age (???)

Pre-drilling the 18' panels on the workbench(trailer) made it much easier to screw it down with even rows of screws. When reaching across a panel on a 9/12 slope, to just poke the screw into the hole is easy. To line up and punch the screw through would have been much more difficult!

Sunday :
This starting with the sunrise is getting to be a habit....
Too bad the temperature wasn't a little higher than 4C.


Here Lionel is helping me fit the panels around the skylights. This one was a measure twice cut once. Put the panel up.... measure again, cut again. Not as easy up on the roof as on the trailer.


At the end of the day the panels are almost all done!.


We used a 7 inch metal cutoff blade in the skil-saw for most of the cuts. (Well 6 of them actually). It is weird having the blade on the skil-saw get smaller during a cut. Then the blade would try and walk up on the metal.
I'm hopling these wheels will work for heavier metal for other projects.

The roof looks good.

Older bones always feel a little slow when strong young fellars are around to do the heavy work!

Those pictures! Now I want to make a trip to Radar Hill beach!

Is it normal to use install purlins over a sheethed and papered roof in your part of the country when installing a metal roof?

Metal roofs create allot of condensation in my part of the world, and dealing with the moisture is why we put down tar paper if we install metal onto a sheethed roof. The other option is to just install the metal over purlins and deal with the water that drips off of the metal when the tempatures change, which create condensation. Insulation under the metal helps in this installs, but when not used, the metal "sweats" on a regular basis.

If you don't have humidity, and this isn't a concern, then I can see the advantage of the purlins for a place to work from when installing the metal. I don't see how it would help the roof in any other regard, and in fact, screwing the metal into the sheething should give you a stronger roof without the purlins.

My concern is that the metal will form condensation on the undersides of the metal when the tempatures change. Having that small cavity between the metal and the paper will allow water to form and drip onto the paper. The purlins will form a dam no that water and hold it in place. Over time, this will lead to those purlins rotting on you, and then your roof coming loose.

On the roofs that I'm familiar with, you install the metal directly to the sheething over the paper. The paper catches the small amount of moisture that the roof creates from condensation and allows it to flow down and out of the roof.

I apologize for bringing this up and hope I'm not being critical. I'm a contractor and allot of the times I see building practices done in the North that are totally knew to me that I don't understand. Hopefully this is the case and it's just another of those things that I don't know anything about.

Don't apologize Eddie, your comments are always welcome.
This is my first real build and I could only absorb so many things at once. I am always looking at what I do to learn 'for next time' if nothing else.
After getting back from Denman this week I found your Container Barn thread and wished I had seen it before. It would have been better if I had clamped my busted tape measure along the peak. By the time we got the panels around the 2 dormers we were off enough on the vertical lineup for some bad words to slip out.....

I went with the purlins on top for a variety of reasons. One main one was to give me a chance of working up there during installation. Not having a known 'crew' at the start I planned things so it was doable by myself with some unskilled help.
Condensation is a problem here, so I have vent spaces from the eave soffit area through the plywood/paper to the metal and a vent strip at the top under the ridge cap. I think this should keep the moisture buildup under control.
The attic space will be insulated and vapor barriered before the gyproc goes on.

Eddie:
One part I don't undertand is your comment about the roof being stronger without the purlins. Do you refer to being able to walk on the flat parts of the panels? With this roof pitch no one will be walking anywhere....

 

[EddieWalker]

I was refering the the strength in the metal. Even with four foot spacing of purlins, a metal roof will have a small amount of flex. The less flex that you have in your metal, the longer your srews will last and the stronger your metal will remail. One big advantage to using sheething is that it supporst the metal over it's full length, not just everywhre you have a purlin. As for supporting the load of a person walking on the roof, I've heard you can go 8 ft between purlins on an R Panel type metal roof, but that is just way too much flex for me.

The secret to the metal not leaking is the gaskets in your screws. Tighten them just enough to get the rubber to bulge, then stop. Too tight and the rubber will break. Too loose and it doesn't create a water tight seal. When the metal moves, it's just a matter of time until the rubber gaskets weaken. It usually takes decades, so it's not something you need to worry about. The difference in your application is minimal.

My purlins are on 2' spacing so the metal is pretty well supported. We were very careful on the screws with the rubber gaskets.

Forget about hauling my kubota, this trailer almost paid for itself on hauling the materials for this project. Delivery charges would have been ~$1200, it costs us only an extra $15 to take it off island for a load, plus we get an excuse to try out some more of the restaurants in the area around Courtenay/Comox. It also makes a wonderful 16 foot workbench for working the long material.


Here I am putting on the last piece of ridge cap. This was the worst part of the job, with no where to sit or anything... You don't need to guess hard where I was feeling bruised for several days...


Thats where we got on the last trip. We still have the gable ends to finish and some more flashing around the dormers, but it will keep the rain out.

We got up for another weekend work party... Arriving near midnight friday we were late to rise on Saturday morning. The water was calm in the morning but a breeze came up later making it a little cool working in the open loft area.


This weekend's projects were to get the loft floor down and the end walls framed and sheeted. Once the floor was down this became the 'Dance Hall'.
Here is the back wall going together. We got this far on the front wall. These weekend trips are always a challenge. What are we going to run out of first? Materials, Time, or Energy.
Usually it is running out of time. This weekend it was materials and energy.
The last photo is cropped to show the idea for the loft. The railing will be removable for loading furniture etc. up there.


For those of you wondering , this is a tractor project. My forks make a wonderful elevator for sheets of plywood. And then putting all the tools away at the end of the day.

Nice work Denmansoft! I'll look for your place the next time I'm racing across the island during the Ferry-to-Ferry cross island race of death (got to beat the big campers to the Hornby ferry lineup)!

 

[denmansoft]

Now you know why I got a Kubota not JD! I figure Some of you racers will see me crossing the road to the rest of our property. I've got a Yellow strobe for the Rops. It gets scary when a block of 25 cars come screaming around the corner and I am crossing the road with the flatdeck trailer....

I'm sure you'll have the Ferry schedule memorized pretty soon. You'll know when to stay off the road!

Actually, I always "want" to take my time getting there but after the mainland ferry and the Denman ferry, the kids are getting owly and I just want to get to Hornby without another ferry wait. It's a long day getting there. It's even worse going home since I usually end up trying to make it from Hornby to Vancouver, WA in one day.

 

[denmansoft]

Which route do you take across the island ? There is more than one and the west route is far less of a white knuckle race. It still goes through our place.

I know both the routes. I usually take the route that the slow moving traffic in front of me doesn't take!

Usually the west route. It's an easier drive.

 

[denmansoft]

Our trips up to the island are a nice break, We drive about 15 minutes at the start and end and then 2 hours in between the ferry rides. It is 4 hours elapsed time but with a leisurely pace. Here is a shot of the MV Mill Bay coming in to pick us up. This ferry is known as the 'most beautiful shortcut'. It runs across the Saanich inlet. We could drive around in about the same time, and fight traffic etc.


The Mill Bay only holds 18 cars so we have to time it right to get on. 25 minute ride.
The ferry to Denman island holds almost 50 cars 10 minute ride.

This past weekend was Pouring the floor. It rained most of the time except for Monday when we actually poured!
The cement truck was able to back in on the south door with a full load. He had enough chutes to place the cement almost to the back.


The ground is pretty soft on the north side still and with all the water we were concerned about the top heavy load. After unloading 2/3 of the cement we were able to move the truck to the north door.


When I was ordering the cement I didn't have my original calculations handy so re-calculated on the spot. I allowed for extra but forgot about the shelf along the south wall to cover the rock.... We had 2 shovel fulls excess... Too close for my liking but on the other hand I did save $200 for what would have been an excess cu.Meter of concrete. Here the floor is placed and screeded. Waiting to set up for the finishing.

It was a long day for the guys working the cement. I was only supervising. I think that is what you call it when you watch because you don't know anything about what is going on?

Thats not a supervisor.. Thats a foreman.
