Attaching the roof and the strengtheners
Step 9. Fixing the lower roof.
Lift the two lower roof pieces in position and hold them in place with a couple of clamps each side.
Drill and bolt through the 1 1/2" x 3 1/2" (90mm x 45mm) wood, and the batten it rests against.
There will be a bolt each end of both lower roof pieces, four altogether.
Use 4" (100mm) long bolts.
Step 10. Fixing the upper roof.
Lift the roof piece with the attached batten in place.
The batten should sit neatly into the apex notch.
Bolt the upper roof to the lower roof, through the 1 1/2" x 3 1/2" (90mm x 45mm) wood that runs the length of the lower roof.
Use six galvanized bolts 5 1/2" (135mm) long spread out evenly along the length of the roof.
Next put the other side upper roof on. You will need someone to help hold it in place until you get a couple of clamps on.
Fix it in place with six bolts to the lower roof (the same as was done on the other side) and six bolts along the apex.
Use 5 1/2" (135mm) long bolts at the lower roof and 3" (75mm) bolts at the apex.
Step 11. Inside fastening and strengthening.
Add 12 angle screw ties (six each side) on the inside of the playhouse where the side walls meet the roof.
Then measure and cut 1 1/2" x 1 1/2" (45mm x 45mm) wood to go all around (walls and roof) the middle of the inside of the playhouse.
This is to add a bit of strength to the plywood walls and roof.
Fix the strengtheners with glue and screws BUT DO NOT screw or glue the ends of any of the strengthener pieces, as doing so would prevent the playhouse from being easily dismantled.
Step 12. Round the lower roof corners.
Round the lower roof corners with a jig-saw.
This is to take the sharp point off the lower corners of the roof.
