Covered Bridge Roof Framing
I had some time today to work on my covered bridge some more. I ripped up some strips of pine and cut some rafters. I made up a pattern and cut about 40 rafters. They are notched to fit over the frame of the truss. Next I made up a simple jig so I could glue up roof "A" frames with a notch for a ridge pole. when the glue dried enough, I notched two so they would fit over the cross timber at the ends of the bridge. I then used some scrap and clothspin-clamps to hold up these first two "A" frames at the end of the bridge. I inserted the ridge pole and erected the rest of the rafter "A"frames.
above are the rafters in place. Every thing is glued using TiteBond III. very few nails are used.
Here are the rafter "A"frames. the short "collar- tie" at the top holds them together and supports the ridge pole.


I only used the TiteBond to hold all the siding in place--no fasteners. We will see how long it holds. I think it will be indefinately, though a few may loosen up over time.
I use silicone to hold the shingles onto the roof, I have also used it for repairs on the siding of my 20 year old bridge which was glued with epoxy which seemed hold pretty well.
