Building a roof cover for your kennel is simple when using chain link fencing parts. A Center 1"3/8 diameter ridge pole is available from Home Depot or Lowes. Using perpendicular brace clamps to create the peak attach the ridge pole across the kennel. Remember to give enough slope to the tarp so water and snow / ice can slide off. The tarp show be fastened at all the grommets and not sag in anyway to hold water. Water is heavy so do not let it collect on the roof it can collaspe the kennel and injure your animal. Also you will need to anchor the kennel so wind will not pick up and send the kennel sailing across your yard.
