Roof options for your gazebo

 

A variety of roofing options are available and three styles are discussed here. Redwood slat roofs are economical, easy to install and offer varying degrees of protection from the sun. Wood shingles can be installed over a paper and plywood base or can be nailed directly to spaced slat sheathing which is constructed similarly to the slat roof. Shingled roofs offer full protection from the sun and rain.

Redwood Slat Roof

Slat size, spacing and angle determine the amount of light and sun exposure inside the gazebo. For the fairly exposed design shown here, use one of the 1x4 redwood slats for 3-1/2-inch spacing. Pre-measure and carefully mark the rafters with slat positions for faster and easier installation. Snap chalklines down the center of the rafters to guide the 22-1/2 degree slat-end trims. Nail the slats directly to the rafters using two 8d nails per bearing. Predrill holes at slat ends to prevent splitting.

 

 

   

Shingles Over Spaced Sheathing

Follow the basic slat roof construction steps. Add two more slats at the roof's edge to simplify installation of the starter course. Space the rest of the slats five inches on center or to match the weather exposure. Other installation details are the same as for shingles installed over plywood sheathing.

Lay and staple 36-inch wide roofing paper in layers as shown. Begin installation with the starter course made up of a double row of shingles overhanging the sheathing by 1/2 inch. Snap chalklines to ensure that additional courses are installed in straight lines. Weather exposure should be slightly less than one third the total length of the shingle. Stagger the gaps at least 1-1/2 inches and leave 1/8- to 1/4-inch spaces between shingles.

Shingles Over Plywood Sheathing

Each two-piece section of sheathing is cut from one 4x8 sheet of plywood. Use 8d nails to install the roof panels, allowing 1/8-inch expansion gaps at the joints. Attach metal drip caps at the eaves.

Lay and staple 36-inch wide roofing paper in layers as shown. Begin installation with the starter course made up of a double row of shingles overhanging the sheathing by 1/2 inch. Snap chalklines to ensure that additional courses are installed in straight lines. Weather exposure should be slightly less than one third the total length of the shingle. Stagger the gaps at least 1-1/2 inches and leave 1/8- to 1/4-inch spaces between shingles.

Nail shingles with two roofing nails approximately 3/4 inch from each edge and 1-1/2 inches above the butt line of the next course. Nails must penetrate at least 1/2 inch into the sheathing. Use longer nails on the ridge caps to penetrate the sheathing.

Ridge caps are available ready-made for easier installation or make your own. They should be trimmed to 4-5 inches wide with a 35-degree bevel on one edge. Install with alternate overlaps and with two nails on each side 6 to 7 inches above the butt edge. Finish at the peak with shingles trimmed to about 8 inches from the tail end.

Finial

To prevent water damage to the kingpost and rafter joint, attach metal flashing to the roof peak before toenailing the finial to the kingpost. Caulk the joining edges and any exposed nail heads.
