How to Frame a Carport to the Side of a Home
- 1). Measure out the space where your carport will be built. A carport for a single car requires a 20-foot-long by 12-foot-wide space, while a double car port needs a 20-by-20-foot space. Mark this area out on the ground with a rope or hosepipe for ease of viewing. Clear the area inside this space, digging out any grass using the shovel. Level and compact the ground using the plate compactor.
- 2). Cut six pieces of 4-by-4 timber to 8 feet long using a bench saw. Cut two of the 2-by-4 pieces to 5 feet, 5 inches long, and another to 11 feet long. Cut two of the 2-by-4 pieces to 6 1/2-feet long and four of the pieces to 20 foot long. These will form the wooden frame of the carport.
- 3). Drive concrete deck anchors into the ground in the corners of the compacted ground using the mallet. Drive another deck anchor into the ground midway between the two anchors on what will be the back wall. Drive the final two deck anchors midway between the corner anchors on what will be the side walls. Drive the 4-by-4 timbers into the anchors.
- 4). Screw a 20-foot beam to the wall of the house, between and at the top of the beams. Use a masonry drill bit in a hammer drill to make the screw holes that screw the beam onto the wall. Screw the 2-by-4 pieces to the wooden frame at the top of 4-by-4 beams on the outside of the frame. Screw the 2-by-4 beams together at the corners.
- 5). Screw the two 4-by-4 beams beside the house to the wall as you did with the 20-foot beam. Set up your step ladder and ensure it is secure. Use the step ladder to gain access to the top of the frame. Screw one 20-foot beam lengthwise to the top of the frame on either side. Screw the final 20-foot beam lengthwise down the middle of the frame for extra support.
- 6). Measure and cut your plywood sheets to cover the flat roof of your carport. Screw the plywood sheets onto the roof, putting screws into the three roof support beams to fasten the plywood onto the roof firmly. Roll out roofing felt across the plywood sheets. Nail the roofing felt to the plywood. Cover the felt in bitumen paint to provide a fully waterproof surface. Paint the wood frame with varnish for protection.
