16×16 Gable Roof Pavilion Plans

by Ovidiu


This step by step diy woodworking project is about a 16×16 outdoor pavilion roof plans. This is PART 2 of the square pavilion project, where I show you how to build the gable roof with a 6:12 pitch. Take a look over the rest of my woodworking plans, if you want to get more building inspiration. Premium Plans for this project available Here. Check out the Shop, as well, for full list of Premium Plans.

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 16×16 pavilion roof



Use 2×6 lumber for the rafters. Use a miter saw to make the cuts to the boards. Smooth the edges with sandpaper. Make the notches to the rafters, as shown in the plans. Mark the lines before doing the cuts.



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 rafters to the beams. Use 1 1/2″ structural screws for the rafter ties.

Roof sheets

Roof sheets

Use 1/2″ 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.

Side roof trims

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

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 pavilion and to protect them from the elements.

what will be the plan for 12 X10 using 6×6 post

John Wagner -

I like the 16×16 pavilion. Do you have the dimension differences for the roof cause I would need 8/12 pitch. thanks John

jackie -

I want to build the 16’x16′ gable roof covered patio but attach it to my gable roof house. Can I eliminate 2 of the posts
and attach to my house wall?
Or bolt 2 of the posts to the house?
Has anyone done this?

Matthew -

For a more robust timber frame look could you use 4x6x10 for the rafters and increase the spacing to 29″ or 43.5″ for 6x6x10?

Ovidiu -

No, because 3/4″ plywood doesn’t work on those spacings

Matthew -

Sorry, I should have given more details. I was thinking about using heavier timber, 6×6 or 8×8 for posts, and 6×10 or 6×12 for cross members/beams. I was thinking a heavier rafter would look more appropriate than a 2×6. Spacing isn’t a problem as I plan to put 3/4 or 1” board on top, and/or purlins instead of plywood and then Tin/mental roofing. Thoughts?

Liz -

Will this construct support metal roofing?
