Re: adding a roof to a mobile church


This appears to be a structure that was put together as 3 pcs, so i thought it was a triple wide but there is no metal frame on the sides, just in the middle. It wasnt a single wide that was built on to, it was installed this way when it was set up but im not sure how they hauled the 2 side pcs in. Because i was expecting to see 3 frames underneath, but no. I will try to take more pics tomorrow underneath and inside.

its only 23'3" wide so that means each section is less than 8 ft wide

Re: adding a roof to a mobile church


It sure sounds like a single wide with the 2 sides having been site built. Wish I could crawl under it and see how it was put together - curiosity is getting the better of me.

Re: adding a roof to a mobile church


ok, so we tore off the front porch and all the underpinning and have a much better understanding of how its made. Its would be considered a modular office unit according to our local mobile home mover. Its a 9 ft single wide frame in the middle and then the two 7ft sides are on piano hinges and so the walls, floor and ceiling swing up, in, down for transport. He said they are horrid to move and he quoted me a price of $7k to move so its not worth selling. And for that cost to move, its not even worth giving away as a storage building.
The middle part that is on the metal frame is built on 2x6 joists, but the 2 seven foot sides are 2x3s sandwiched between 2 sheets of 1/2 plywood and then a sheet of 3/4 plywood on top of that. Thats the original construction. Then whenever the church was brought to this site, it was freshened up with another layer of 3/4 advantech installed on the inside.

So is there any way we can support the outside edges enough to where we can install trusses on the walls? (the walls would have to be replaced with 2x4s or reinforced since they are only 2x2s). Such as the suggestion to put beams across the piers.
Or is it just not feasible considering the construction?

Re: adding a roof to a mobile church


We tore off the bottom pc that was holding the underpinning so that we could see the edge of the construction for both the middle part and the 2 sides.

Middle: Typical 2x6 joists with 2 sheets of plywood on top

Sides: 2x3s sandwiched between 2 sheets of 1/2" plywood with a pc of 3/4 plywood on top. Then the outside walls are built on top of this. The inside has yet another layer of 3/4 advantech on top of the original 3/4 plywood.

Re: adding a roof to a mobile church


Here is 2 pics of the inside to show how the roof is on the inside.

the 2 sides are only 7ft tall
the middle is 8ft tall and has headers across it. im assuming to give strength to the sides. All of that was probably installed after it was put in place as it doesnt seem possible for the ceiling to swing down for transport with those headers there.

Re: adding a roof to a mobile church


As long as the 2x3 is adequately supported it will support the wall and roof load. The problem with the 2x3s is where it spans between supports. The plywood helps but I don't know how much.

IMO it would be best to provide more support under the outer edge. Ideally you'd have a continuous block wall for it to rest on but it could also beefed up with wood or steel to make the edge more rigid/stable.

Re: adding a roof to a mobile church


We are very strongly considering putting the trusses over it pole barn style to that the weight will not be on the frame. That was suggested originally, but we were hesitant because of the appearance. However, have thought of some ways to make it look good. The insurance company was very negative about a total rebuild so i think they would be happier with the roof over too. I will post some more pics as we go. So far, putting the beam across the piers seems like the most feasible way to reinforce the sides.
I think someone earlier said that a 4x4 would not be sufficent? Even across a 5ft span? So a 4x6 is the minimum?

Re: adding a roof to a mobile church


I'm not sure why but ins companies don't like modified MHs. My house consists of an older single wide with additions built across the front and back with a block foundation and roof/attic. For the most part it looks like a conventional stick built house. But because I don't have a title for the trailer there is only one insurance company I've found that will insure my home. The bright side is I was able to pay cash for the place and build the additions as I had time/money.

I don't know if 4xs will work or not [I'm just a painter]. Generally lumber is strongest when the flat side is on the side - 2x6 laid flat is weak but when the 6" side is pointed up it is stronger.

Re: adding a roof to a mobile church


It shouldn't be a big deal if everything is permitted/inspected. If I had a title for my MH I could get MH insurance including the additions .... but MH insurance is higher than comparable convention home insurance. Most non MH ins companies won't insure a house that has a MH inside it. I have decent fire and wind insurance but it doesn't include theft or liability ..... but at least compared to most homeowner policies - it's cheap.

Re: adding a roof to a mobile church


You could do both. pole barn with support posts run right thru the walls with beams above the walls and set trusses on those beams.
But the outer floors sound mickey mouse at best. You could use 2 2x10 for a beam under the walls and then you could fit floor joist under there too. Or maybe 2x8s.

Re: adding a roof to a mobile church


well we got most all the 4x6 beams placed under the wall on top of the piers. Thanks to the person who recommended this! It really helped.
We are still going to help support the trusses with beams too so that they arent really sitting on top of the mobile home wall or atleast not all the weight.
Where the joints of the 4x6s did not end on a beam, we are going to put blocks under the joints or support in some way. Just thought I'd mention that before someone pointed it out

Re: adding a roof to a mobile church


Yeah, I would have cut them to fit the post and been picky on the length I bought to lower the waist. But that is what I had in mind.
Any nails going into that stuff should be hot dipped galvanized or the treatment will eat them.

Re: adding a roof to a mobile church


I wouldn't be leery of mounting the trusses over the exterior stud wall now [assuming the studs are 2x4 or larger] Not sure what your spacing is with the block piers but 8' or less would be ideal.

Re: adding a roof to a mobile church


ok, so we have been working on it constantly and I have been so exhausted each night that I didnt have the energy to post our progress.
So we didnt take the tin off the sides.

We have made so many mistakes that I hesitate to even tell it, but I will take my lumps and learn as may others who read this before starting their projects.
We dug out holes with post hole diggers, approx 40+ inches deep. Its been raining here for weeks on and off and the ground was saturated so we put about 12" of dry quikcrete in the holes, then set the poles. We did not fill in the holes around the poles with quikcrete at this time because we wanted to see how the truss would sit on there.
Which brings me to another "not correct" thing we did. We had already ordered the trusses before we decided to NOT tear down the walls after all. (insurance company wouldnt insure it if torn down and rebuilt). So we had to reinforce the 2x2 walls somehow and considered building a wall inside the trailer, along the current 2x2 wall. In the end we decided to sort of support the roof, pole barn style, and this would also give us the chance to have a frame around it to put siding on and therefore hide the ugly.
The problem was that the trusses were made to fit on the trailor frame, so they would only sit on the one 2x8 that we mounted to the side of the post.

Another "wrong" thing we did was we turned the 4x6 beam flat against the trailor wall. We did this because the beam is now inside the overhang so I went from a 12 " over hang to an 8". If I had turned the beam the other way, I would have been left with a 6" over hang.

We plan to put another 2x8 BETWEEN the posts and toenail it in, then screw to the existing 2x8 thereby forming a stronger "girder" for the truss to set in. The reason we didnt install it before we put the trusses on was because the 2x8 will fit under the eave and might have to be cut at an angle to fit snugly up in there.

Remember how I said the roof was in 3 sections, well we just tore off the side ones and installed the beams and 2x8, then when we were finally forced to tear out the middle section, we discovered the 2 end walls (in the middle section only), were built out of 2x4's and were a full 8ft tall. Rather than tear that down, we found out we could put a rough cut 2x4 on top of the 2x8 and it was the same height all around as the middle section.

So now it would REALLY have been best if we would have went ahead and put the other 2x8 between the beams and screwed it all together. But we thought we would test a few trusses and see how it all fit and determine what angle we would have to cut the edge of those 2x8s on.

However as we were raising the first truss, my dad and brother showed up and helped us raise several of them. He didnt realize we were adjusting and figuring out as we went and that the posts were not cemented in place yet. So when they left, I realized that the wall wasnt straight and so we had to unscrew some of the trusses and use heavy duty rachet straps around opposite posts to pull them in and keep the walls straight and 24' apart. The trusses hanging like that were pushing them out, even with bracing outside.

So yes, Ive been leveling my beams on the outside and filling around them with quikcrete after my trusses were up, we also are adding the 2x8 between the posts after the trusses are set. I know its backwards but the trusses wouldnt set over both 2x8s without the inside 2x8 being angle cut on the edge. I still dont know what angle to cut in on.

AS were were going along,(this process lasted for days with rain almost every day, so we would work frantically trying to figure out ways to do things with a storm cloud bearing down) different people showed up to help and it actually made it worse in some ways, as they all had a different way of doing things. They werent usually there at the same time. One was adamant that the eaves be kept straight and another felt the overhangs should be exactly the same. Yet another felt it was more important that the peak be kept in line, he said you could always trim the overhangs along the edge of the eave to make them all straight.

Finally the rains are diminished for a few days and so we will tear the tarps off of everything, measure and adjust and see what we have.
