A great shed, creative design, step by step instructions.  Was very careful in leveling aspect because I knew the alienation depended on it.  All in all everything went well till the last two roof panels.  Had to catch the top hole positions first to find I had to drill holes for the rest with not being able to fasten the two middle holes on both panels.  Patch and silicone the last remaining four middle holes.  But it’s a nice size beautiful shed.  Will reinforce it inside for here in Puerto Rico we sometimes get stronger storm winds.
