1/2-inch plywood sheathing
Roofing felt
Roofing shingles
Roof nails
Circular Saw
Cordless Drill
Rafter hangers

Building a mobile home roof is best done right over the existing roof. This will give you both a ceiling and a barrier between your living space and the extreme cold, heat and rain. This can make for some good insulation and air movement.

A mobile home roof then is built basically the same way you would raise a roof on a wooden frame structure.

Build End Frames

Begin building your roof by starting at each end. Build the frame using the 2-by-6 rafters and a 2-by-10 top stringer. You will need several top stringers, but you should begin with the ending frames first. Then overlap the stringers by 6 inches to complete the stretch from one end to the other.

Take your time with this step to make sure that the front and end frames are square and level. You can also use these roof frames as templates for quickly building the others. Take the time to build a frame for your roofing—don't just span a rafter from the stringer to the edge of your mobile home roof. You will lose a lot of strength and stability.

Build Rest of the Rafters

If you are using one of the other frames as a template, use a large piece of plywood and scrap blocks of wood for the corners. Once you have them in place, simply lay out the rafters for the frame. Use rafter hangers to quickly assemble each rafter frame. You will need enough to place one frame every 16 inches on center.

Lay Down Plywood Sheathing and Roof Felt

Using 1/2-inch plywood, lay down the sheathing over the entire roof. Cut around openings for the roof and plumbing vents. Once the sheathing is installed and secure, lay out the roofing felt, stapling it to the sheathing.

Install Shingles and Soffit

Starting at the edge of the roof, start laying out the roof shingles, securing them with roofing nails. Make a chalk line to ensure that the first row is level and straight. Once the first row is laid out, the rest of the roof goes very quickly.

Cap off the top by laying the shingles one over the other the entire length of the roof. Install the soffits to finish off the bottom of the rafters, and you have a new, long lasting mobile home roof.
