I just finished pulling the roof panels down from around my roof vent. What it looks like is they are just wedged into the aluminum extrusion that holds the edge of the panels. Is this all that holds the roof "beams" in place or is there supposed to be a screw or something in the end of the 3/4 x 1-1/2 roof "beams"? Someone attempted a fix earlier in the life of my tin can and the wood pieces that they put in are just wedged in. Is this the way it came from the factory? And is the roof skin just laid across the wooden supports or are they attached with screws or nails. Sorry if these are ridiculous newbie questions so be gentle if they are.  |

A lot of Shastas are not framed well at the roof vent. Mine were floating pieces but not after the build...I "toe screw" everything with trim screws and also shim the vent as high as possible with the existing roof metal. (1/4" to 3/4" depending on the slack) Raising the vent will facilitate run off. Most later roofs (post mid 50s) were not attached to the rafters. There was a layer of insulation just under the metal. Nails would be VERY BAD: travel vibration just loosens them. Wonder if there was a reason for Dreaded Twisty Nails?  |

Those things are a must for Twisty Nails. Just gotta be careful not to use too much air pressure or you whill go right through the wall or ceiling. LOL... Gotta read the instructions and runs some tests on scrap wood is all. The roof slats or beams if you will in the Shasta Im working on did not even mount over the walls. Instead they ran the curb all the way around the walls first and then toe-nailed the slats or beams inbetween the curbs giving little to no support at all. The only thing the framing seems to be there for on Shastas is to hold the metal and the interior paneling 3/4 of an inch apart. Geeesh... When I rebuilt mine I overlapped the 1x2 and 1x3 beams/slats over the walls and then ran the curbing inbetween the slats/beams.... It's all in my videos. |
