Intro: Replace Canvas Roof With Corrugated Steel
After a windstorm ripped the canvas covering from my portable shelter, I replaced it with corrugated steel roofing. To prevent it sailing away with the next windstorm I anchored the frame to the ground with 3/8" spiral ground anchor screws. If more protection is required the sidewalls could be covered the same way.
Step 1: Strap Detail
This is a closeup of a strap attaching a nailer to the pipe frame of the building. The straps are cut to the required length from a roll of perforated pipe strapping and attached with heavy duty wood screws.
Step 2: Roofing Nailers
Two by fours are fastened to the pipe roof frame at 16" spacing intervals.
Step 3: Nailer Overlap
The nailers are staggered and overlapped so that the pipe straps are not too close to the ends.
Step 4: Tiedown Anchor Straps
Four tiedown anchor straps keep the structure from blowing away.
Step 5: Anchor Screw
Ground anchors are screwed into the ground about 18" .
Step 6: Anchor Strap Top End
The top end of the anchor strap hooks over a bolt through a pipe strap wrapped around the building frame. I let roofing overhang the sidewall in case I decide to sheet up the walls too. The structure is still portable if you have enough friends to help you move it.
