24×24 Detached Garage Roof Plans

This step by step diy woodworking project is about free 24×24 garage gable roof plans. This is PART 2 of the 2 car garage project, where I show you how to build the roof. In this article you will learn how to build and attach the overhangs and the roof. I recommend you to read the local building codes, before building the garage, so you understand the legal requirements. Make sure you take a look over the rest of plans to see alternatives and more projects for your garden.

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 24×24 garage gable roof

Building-the-overhangs—2-car-garage

First of all, you need to build the overhangs for the double garage, as shown in the diagram. Drill pilot holes through the rafters and insert 3 1/2″ screws into the blockings. Place the blockings equally spaced and align the edges flush.

Fitting the overhangs

Fit the overhangs to the front and to the back of the garage. Align the edges with attention, drill pilot holes and insert 3 1/2″ screws to secure them into place tightly.

Attaching-the-roof-sheets—24×24-garage

Next, attach the 1/2″ plywood sheets to he top of the garage. Start with the bottom left and go to the top of the roof structure. Leave no gaps between the sheets and insert 1 5/8″ screws, every 8″ along the rafters.

Side roof trims

Fit the 1×6 trims to the sides of the roof. Use 8d nails to secure the trims to the trusses.

Front and back roof trims

Use 1×6 lumber for the front and back roof trims. Make the angle cuts with a miter saw and then lock the trims into place with nails.

Fitting the roofing – Double Garage Plans

Cover the roof of the garage with roofing felt, making sure the strips overlap at least 2″. Secure the tar paper to the plywood sheets with roofing staples. In addition, cut a large piece for the top ridge. Fit the side drip edges over the roofing felt, while the bottom drip edges should be fit under.

Read the instructions labeled on the asphalt shingle packs before installing them into place tightly. Start with the bottom left side of the roof and install them all the way to the top.

Attaching the housewrap

Wrap the garage with homewrap.

Fitting the siding to the double garage

Attach the T1-11 siding sheets. Alternatively, you can go for metal sheets from the very beginning and not use OSB and siding.

Double Garage Plans – Side View

Fit the 1×4 trims to the corners of the garage, to enhance the look of the construction.

24×24 Garage Plans – Back view

Fit the side door and window to the garage and then attach the decorative trims.

2 Car Garage Plans

Install the 9′ garage doors to the front of the garage. In addition, fit the side door and window to the structure. Make sure you take a look over PART 2 of the double garage project, where I show you how to build the frame of the structure.
