This wooden lean-to pergola will enhance the appearance of your home and form a decorative porch area where you can relax and entertain. You can choose to cover the roof with polycarbonate panels, in which case the advantageous sloping design of the roof will allow water to flow off. The accessories/screws needed for attaching it to the wall are not included in the delivery. Please note that wood is a natural product and can show imperfections.
