How To Build a Carport Roof

This step by step diy project is about how to build a carport roof. After building the frame of the carport, you need to attach the gable ends and the roofing. Make sure you take a look over PART 1 of the 3 car carport plans, so you understand what is needed to build the structure from the very beginning. Take a look over the rest of my woodworking plans, if you want to get more building inspiration.

When buying the lumber, you should select the planks with great care, making sure they are straight and without any visible flaws (cracks, knots, twists, decay). Investing in cedar or other weather resistant lumber is a good idea, as it will pay off on the long run. Use a spirit level to plumb and align the components, before inserting the galvanized screws, otherwise the project won’t have a symmetrical look. If you have all the materials and tools required for the project, you could get the job done in about a day. See all my Premium Plans HERE.

How To Build a Carport Roof

Fitting the roofing sheets

Fit the 3/4″ plywood sheets to the roof of the carport, starting with the bottom left side of the structure. Align everything with attention and secure the sheets into place with 1 5/8″ galvanized screws. Leave no gaps between the components for a professional result and continue the process till you have covered the whole structure.

Fitting the side trims

Attach the 1×6 trims to the front and to the the back of the carport to cover the ends of the rafters. Use 2″ brad nails to secure the trims into place.

Building the gable ends

Use 1×6 slats for the gable ends of the 3 car carport. Cut both ends of the slats at 30 degrees before securing them into place with 2″ brad nails.

Building the overhangs

Build the overhangs from 2×6 lumber. First, you need to make 30 degree cuts to both ends of the overhnags using a saw. Smooth the edges with sandpaper.

Cutting the overhangs

Next, you need to make a cut to the bottom of the overhangs, as shown in the diagram.

Fitting the overhangs

Fit the overhangs to the sides of the carport, over the gable ends. Align everything with attention, drill pilot holes and secure them into place with 3 1/2″ screws.

Fitting the roofing

Install the roofing felt, starting from the bottom left of the roof. Secure the paper to the roofing, using a stapler. Make sure the tar paper overlaps at least 2”. Don’t forget to cover the top ridge with a 14” strip of paper .

Start the first course of shingles with a full tab, the second with 2 1/2 tabs, the third with 2 tabs, the forth with 1 1/2 tabs, the fifth with 1 tab, the sixth with half tab and the seventh with a 3 tabs.

Build a 3 car carport

Last but not least, you need to take care of the finishing touches. Therefore, fill the holes with wood and after it dries out even out the surface with 120-220 grit sandpaper. Apply a few coats of stain or paint to protect the components from the elements and to enhance the look of your new carport.

You can easily add lattice panels to the sides and to the back of the carport. The panels will act as privacy screens and it will further protect your cars from rain and snow.

Building a large carport

You can adjust the size of the carport so you fit as many cars as you want. This project is easy customizable to your particular needs. Remember that you need to adjust the size of the components so they suit your particular own needs and you have to check the local building codes before starting the building process. Read PART 1 of the project to see how to build the frame of the carport.
