This step by step diy woodworking project is about a 16×24 outdoor pavilion roof plans. This is PART 2 of the large rectangular pavilion project, where I show you how to build the roof and how to attach the decorative trims. The roof has a 12:6 pitch, but you easily adjust it, if you need something else. 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 15×20 pavilion roof

Building the rafters
Use 2×6 lumber for the rafters. Make 26.6 degree cuts to both ends 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.

Fitting the rafters to the pavilion
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 beams into place.

Roofing sheets
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 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.

Gable trims
Fit the 1×8 trims to the front and back of the pavilion. Make the angle cuts to the trims before locking them into place with 2″ nails.

Fitting the roof
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. Make sure you take a look over PART 1 of the project, where I show you how to build the frame of the pavilion.

The page for the 16×24 pavilion roof gives instructions for a 15×20 pavilion roof. Could you please send the link to the correct plans for the 16×24 roof? Thanks!
These are the plans for the roof of the 16×24 pavilion.
Hello, Thank you so much for these plans! They are great! I am trying to build my pavilion with the posts being 16×24 and a roof overhang of 2ft on both ends. Can you draw up plans for that? It would help me make sure I am ordering the correct amount of lumber. Thank you!
Sorry, I can’t help you with that. I don’t design custom plans.
Unless I am overlooking it the materials list is not showing Items A through E.

Hello,
I really like your 16 x 24 pavilion plans. I was wondering if I decide to use tie plates for some of the joints such as the Simpson Strong Tie HL35PC 3-1/4-Inch by 3-1/4-Inch by 5-Inch Heavy Angle Textured Black or even the Simpson Strong Tie Simpson Outdoor Accents APT6-8 x 6-inch ZMAX Galvanized Steel Black Powder-Coat Flat T Strap (8-Case) ( can get an idea of what they look like on amazon.com ). Or the 6×6 Blk Zmax L Strap, PartNo APL6, by Simpson Strong Tie, Pack of 8 on walmart.com
How many would I need and how many nuts and bolts and washers would I need. Also the recommended sizes. Also using the above mention ties would I need to use any on the braces. But at a 45 degree angle tie in those location instead. Ironwood 45 Degree Flush Inside Tie Plate By OZCO Ornamental Wood Ties found on decksdirect.com (for a visual on what they look like). Your thought on this would be greatly appreciated. I’m trying to achieve your creation but use bolts & nuts and washers instead of the long screws. Also how many rafter ties do you recommend and type and the nails or screws to use with them If you were building my way could you point me in the right direction by detailing some of these changes. I planned on using severe weather common 6″ x 6″ from Lowes and either stain or varnish the wood for a long lasting look. Thank you so much for you insght. I’m an amateur DIY guy just trying to build as sturdy as possible and give an aesthetic feel or look to my project. Again thank you for your time.
Sincerely,
Joe Harper
It depends on the type of rafter ties. Technically 2 for each rafter, most likely just one for the bottom. You can use the connectors for the structure but I cannot make a shopping list for that.
What kind of wood is this designed for? Would Western red cedar be strong enough as it’s drawn?
Yes, it works. I has the almost the same hardness as pine.
This is the plan I’ve been looking for. However, I would like to use it to build a two-car Carport. Can I adjust the width and make this plan work for a 20X24? Thanks
Yes, it will work.
