18×18 Shelter Gable Roof Plans

by Ovidiu

 

This step by step diy woodworking project is about a 18×18 outdoor pavilion roof plans. This is PART 2 of the picnic shelter project, where I show you how to build the gable roof. You can adjust the slope of the roof to suit your needs. 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 18×18 pavilion roof

Building-the-rafters---gable-pavilion

Building-the-rafters—gable-pavilion

Use 2×6 lumber for the rafters. Make 45 degree cuts tat one end of the 2×6 rafters. Mark the cut lines to the rafters and then get the job done with a circular saw. Smooth the edges with sandpaper. Make the notches into the rafters, so you can fit them into place tightly.

Fit the rafters to the top of the pavilion, using the information from the diagram. It is important to space the rafters properly (every 16″ on center), otherwise you won’t be able to attach the roofing sheets. Use rafters ties to lock the beams into place.

Roof-sheets---pavilion

Roof-sheets—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.

Fitting the side roof 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.

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.

Fill the holes with wood putty and let them dry out for a few hours. Smooth the surface with 100-200 grit sandpaper and remove the residues with a damp cloth. Apply a few coats of stain or paint to enhance the look of the pavilion.

I need a pavilion / patio cover 18 x 36 and attached to the existing roof of the house (by the 18′) can I just double up this plans to achieve that size? do you have any pergola / pavilion plans size 18×36?

Reply

I don’t have plans for that. Theoretically you can double these plans, but there will be a few modifications, so it’s not that simple.

Do you have any side view of the Part 2 for the 18 x 18 pavilion? I can’t read/see the spacing for the rafters. Thanks

You have the spacing in the second picture. The rafters go every 16″ on center.
