SHEET METAL LIPS AND SAFETY TIPS
When installing the roof metal and siding, create a tight seal by overlapping the
pieces properly and covering the seam on the edge of the metal. Take a moment to
match up the pieces before you start the nailing process: one side of the metal has a
bigger lip that fits over the smaller lip to provide a tight seal. These are located on
opposite sides of the metal sheet.
To prevent smashed fingers, hold the roofing nails with a pair of pliers so when
you miss you don't smash your thumb. I learned the hard way and have a perman-
ently damaged thumbnail as proof. It takes a bit of force to penetrate the sheet metal.
Before you proceed, it's a good idea to let the concrete harden overnight
if possible.
Although you can proceed at this point if pressed for time, it is ideal
to wait 24 hours before you move on to step 8.

Next, create the bottom frame by connecting 2×4s (5×10 cm) — or 2×6s (5×15
cm) for a stronger structure — to the 4×4s (10×10 cm). To do this, place a 2×6
(5×15 cm) over the front face of the 4×4s (10×10 cm) at the front of the build-
ing and drive two 16-penny nails in each end to attach it to the 4×4s (10×10 cm).
Repeat this step with the back of the building and then cut the remaining two
2×6s (5×15 cm) to fit the ends of the building.
The structure may not be exactly 7 feet (2.0 m) deep by 8 feet (2.5 m) long if
things were not entirely square when you started. It's best to measure and trim the
boards to fit the structure as you go. When this step is complete, you will have a
bottom frame for your building, with the four standing 4×4s (10×10 cm) and the
four horizontal 2×6s (5×15 cm) connecting to create the bottom frame.
9.
Now construct the top frame, basically creating a box of sorts. To do this, repeat
step 8 by nailing the 2×4s (5×10 cm) (or 2×6s [5×15 m]) to the top of the 4×4s
(10×10 cm). Use two 16-penny nails at each end. If you live in an area where
there is a lot of snow, it is probably best to use 2×6s (5×15 cm) at the top also to
frame the structure. The box at the top will not be parallel to the ground box but
angled. You will have a triangular space at the top that can be covered with metal
or fiberglass window covering, or simply fencing wire in warmer areas.
10.
Once you've attached the framing boards, it's time to put in the roof rafters. Sim-
ply place five of the 8-foot (2.5 m) 2×4s (5×10 cm) over the top frame that you
just made, running front to back. Space the rafters about 2 feet (0.6 m) apart.
