Before you shingle the roof, install metal drip edge. Then nail a row of starter shingles along the bottom of the roof. Install the rest of the shingles according to the package instructions. Before painting, we filled spaces on the exterior with acrylic caulk. Then we rolled and brushed two coats of top quality acrylic exterior paint onto the trim and siding. When all of this is done, your pub shed will be complete!
No shed, regardless of how well it's built, will last long if it's set on a weak base. Most sheds can be supported by an on-grade foundation, which consists of solid concrete blocks or pressure-treated wood timbers set directly on the ground. The concrete blocks or timbers (aka skids) must be leveled and spaced closely enough to properly support the shed's floor frame. Note that it's important to use solid concrete blocks, not hollow wall blocks, which can easily crack.
One last thing about shed sizes, it’s a good idea to always measure out the dimensions in your own garden before you invest any money. You can do this easily by using a couple of stakes and a string to measure out the space. That’s how the pros do it. Make sure that you leave enough room on all sides of the shed to help with rain drainage and prevent water damage.
