This step by step diy woodworking project is about a 12×16 outdoor pavilion roof plans. This is PART 2 of the rectangular pavilion project, where I show you how to build the roof and how to attach the decorative trims. The roof has a 45 degree slope, so you can easily drain the water or snow. 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 12×16 pavilion roof
The first step of the project is to build the rafters for the 12×16 pavilion from 2×6 lumber. Mark the cut lines on the beams and then get the job done with a circular saw. Make sure you cut out the birds-mouth for a professional result.
Fit the rafters to the top of the pavilion, using the information from the diagram. It is important to space the rafters properly, otherwise you won’t be able to attach the roofing sheets. Use rafters ties to lock the beams into place.
Fit the 1×6 slats to both sides of the roof, for a nice decorative touch. Adjust the width of the trims to 4″ using a saw and secure them to the end of the rafters with 2″ brad nails.
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.
Build the gable end trims from 1×6 or 2×6 lumber. Make 45 degree cuts to one end of the trims, using the information from the diagram.
Drill pocket holes at both ends of the beams and then secure them into place with 1 1/4″ screws (1×6) or 2 1/2″ screws (2×6).
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.
Don’t forget to take a look over PART 1 of the project, so you learn how to build the frame of the 12×16 pavilion. This pavilion is sturdy and it features a very elegant design that puts and emphasis on cost efficiency and durability.

On the 12×16 pavilion plans and you seem to have a high roof with a large pitch. Your 12 x 14 shelter did not have a large pitch roof but I need a 12 x 16 is there anyway that I can use a roof more like the 12 x 14 on the 12 x 16?? Thanks for getting back to me in advance. Eric
It is possible, considering both pavilions have the same width. Use that trusses to this design.
Is it possible to obtain printer friendly versions of the plans?
Yes. Please read the FAQs: http://myoutdoorplans.com/faq/
On your instruction it states to use a 3/4 plywood for the roof. Is it possible to use a 5/8 instead? The reason that I am asking is that I wanted a beaded board look on the inside of the pavilion and lumber stores don’t have that look in a 3/4
Place the rafters every 16″ on center.
I have already place the rafters according to your plan of 21″ to 22″ so what should I do now about the thickness of the plywood?
I would go with the 3/4″, but if you like the look of the 5/8″, you could give it a try. I think it will work.
ok. Thank you. Why do you recommend the 3/4? I am also putting on a metal roof.
Because it’s thicker and it will support better the weight.
How would you cut the rafters to change the roof pitch to a 9:12? I love the 6X6 framing.
How would you cut the rafters for a 6/12 pitch?
Your plans mention using rafter ties to lock the rafters in place. Am I correct in assuming you are referring to something like a Simpson Strontie rafter ties rather than joists?
Yes, you have a link in the materials list to what I’m referring.
Is 6×6 construction necessary? Will this pavillion work with 4×4 posts and crossbeams? Can I use metal roofing instead of wood, tar paper and shingles? Wouldn’t that make the roof lighter and a 4×4 structure more feasible?
Don’t recommend that.
Don’t recommend 4×4 or metal roof?
4x4s. The metal roof is not an issue.
Do you have premium plans for this 12×16 Pavilion?
I have for a 12×16 with a gable roof, but different roof pitch.
