We are about to put rock and concrete roof tile on our house that has been built in 3 sections in various stages of completion over the last 20-25 years. A hobby that got out of hand...
Question 1: Since we've always planned on the tile, the on-site built rafter structures in section 1 and the trusses used for the later 2 sections *should* be ok for tile now. Currently we have plywood, 30# felt, and roll roofing installed. I need to determine if we can safely (weight/stress-wise) install the tile winthout removing the rolled roofing. Additionally, we want to add some solar panels for pool heating, so we need to check the strength of those trusses in that area on the 3rd section. I have CAD drawings that I made of the hand-built section & the truss-companies'-generated diagrams of the trusses. Where/Who/How from here?
Question 2: When we added the 3rd section, we decided to make it 2-story instead of the
1-story that we'd originally designed. Now that we're about add the rock veneer, we have a place that is a problem. The 2nd section (1-story) joins the middle of the 3rd section (2-story) at a right angle. The wall area in question kind of looks like a 28' W x 10' H rectangle with the 28' W x 5'10" H (peak) triangle of the 2nd section gable cut out of the bottom of it. If we do it in rock, we are going to have to add support. I would image it would have to be truss-like structure(s) directly under the rock. Obviously it's too late to get a commercially built truss now, so it would have to be built in-place in the attic. Since there's no interior walls yet in the 3rd section and the gable end of the 2nd section is exposable (just covered in scrap plywood & hardboard to keep the 'coons out ), we can probably still get long timbers in through there if necessary. Or at worst we could pull a decking sheet and load from outside. Suggestions on where to get such a support designed?
