20×30 Carport Gable Roof Plans

Ovidiu 0 GapDice RANDOM PLAN

This step by step diy project is about 3 car carport gable roof plans. This is PART 2 of the triple carport project, where I show you how to build the gable roof. This carport has generous overhangs on the sides and it also features a sturdy design. 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.

How to build a 20×30 carport gable roof

Rafters---20-ft-truss

Rafters—20-ft-truss

Build the rafters for the carport from 2×6 lumber. Use a miter saw to make the 26.5 degree cuts to one end of the beams. For this project I recommend you engineered trusses, which come pre-assembled to the construction site, thus saving you time and money.

However, in this plan I also show you an example for a truss with a 6:12 pitch. Read the local codes to make sure it complies with your local requirements.

Bottom-chords

Next, build the bottom chord for the truss from 2×6 lumber. Make 63.5 degree cuts to both ends of the beam. Lay everything with attention on a level surface. Align the edges as shown in the diagram.

Webs---trusses

Webs—trusses

Use 2×4 lumber for the webs. Mark the cut lines on the slats and then get the job done with a circular saw.

Build the rest of the webs using the info from the diagram. Make the cuts with a saw, as shown in the diagram.

Fitting-the-W-webs

Fit the webs to the trusses and align the edges with attention. Secure the components together by attaching strong tie plates over the joints. Insert 1 1/2″ structural nails to secure the plates into place. Fit the plates on both sides of the truss.

Fit the rafters to the top of the pavilion, using the information from the diagram. It is important to space the rafters properly (every 24″ on center), otherwise you won’t be able to attach the roofing sheets. Use rafters ties to lock the rafters to the beams. Use 1 1/2″ structural screws for the rafter ties.

Gable-end-panels

Gable-end-panels

Use 5/8″ siding sheets for the gable ends. Cut the panels at the right dimensions and then lock them to the frame with 1 5/8″ screws. Leave no gaps between the panels for a professional result.

Fitting-the-roofing-sheets---20x30-pavilion

Fitting-the-roofing-sheets—20×30-pavilion

Use 3/4″ plywood for the roof of the pavilion. Cut the sheets at the right dimensions and then lay them to the top of the pavilion. Leave no gaps between the sheets and then insert 1 5/8″ screws, every 8″ along the rafters, so you can secure them into place tightly.

Front-and-back-gable-end-trims

Front-and-back-gable-end-trims

Fit the 1×8 trims to the front and back of the pavilion. Lock them into place with 2″ nails. Notice the angle cut to the top of the short trims.

Fitting-the-side-trims

Fitting-the-side-trims

Fit 1×8 trims to the sides of the pavilion. Align the edges with attention and insert 2″ nails to lock them into place tightly.

Fitting-the-roofing

Fitting-the-roofing

Cover the roof with tar paper and then install the asphalt shingles. Make sure you also install the appropriate drip edges, so you can seal the shed roof. Read the manufacturer’s instructions for a tight fit.

Last but not least, you need to take care of the finishing touches. Therefore, fill the holes with wood putty and then smooth the surface with 120-220 grit sandpaper. Apply a few coats of paint / stain to enhance the look of the carport and to protect them from the elements.

This carport will shelter 3 cars. The carport has a nice gable roof to drain the water properly and to create shade. I recommend you to read the local building codes before starting the project, so you make sure you comply with the local building codes. Check out PART 1 of the project.
