Like a house or garage roof, a gazebo roof is more prone to wear and damage, finally requiring replacement. A gazebo typically has an asphalt shingle roof because that kind of shingle is flexible, easily conforming to the curves at each roof fashionable — the ridge where two sides of the roof meet. Gazebos often have four, six or eight sides, which translates to a equal number of triangular roof segments that are joined with a cap along each joint. Rent scaffolding so that you can access your gazebo’s roof safely and easily.
Scrape off the gazebo’s present roof shingles with a ripped shovel, pitchfork or similar tool. Work from the bottom edge of the roof up to the summit. Insert the tool’s blade under the underside seams and push it up along the roof to break up the shingles. Eliminate the old felt paper underlayment, and pry up all remaining nails with the claw of a claw hammer.
Pull up all rotting or damaged wood pieces from the roof. Measure the previous pieces you removed, and cut seams from 1/2- to 5/8-inch-thick plywood sheets. Expand the new plywood pieces to the roof rafters with 1 1/2-inch-long wood screws.
Cover the roof with felt paper underlayment, employing a type advocated for your asphalt shingles you pick. Overlap the edges of underlayment pieces by about 6 inches, with each underside edge laying over the top edge of each piece further down the roof. That arrangement prevents water from seeping through the joints between the pieces. Attach the underlayment into the roof using 1/2-inch wood staples spaced about 6 inches apart along each edge of the felt paper underlayment. Smooth the underlayment with your hands to remove air bubbles as you apply the staples with a staple gun.
Measure the length along the base of one side of the roof. Mark that side middle point along the underside, and partly tap a 1-inch-long roofing nail in the mark. Tap a different nail part way to the middle of the roof peak. Bend a chalk line around each nail, then pull on the line taut and sprinkle the line to leave a chalk mark on the felt paper underlayment. Eliminate the nails and chalk line following snapping the chalk line, and also perform the same after creating every single chalk line mark during the job. Duplicate the chalk line marking procedure on all sides of the roof.
Push a piece of galvanized steel drip edging along the base of the roof edge, together with the bent edge of the drip edging overhanging the roof. Mark along the top of the drip edging. Step 3/8 inch downward from that mark, and snap a chalk line in that location. Expand the drip edging with the chalk line mark you created. The extra 3/8 inch retains water from damaging the gazebo’s fascia boards. Drive 1-inch-long roofing nails — with the hammer or a pneumatic nail gun — every 6 ins to attach the drip edging. Use tin snips to cut back the drip edging corners at the ends of each side of the roof.
Cut the shingle tabs of several asphalt shingles, using a utility knife or hook knife. Shingles usually include three or four separate shingle tabs, and about a 6-inch-wide top piece that is hidden when the shingles are installed. Eliminate the tabs, leaving just the top pieces. Align these top pieces so they overhang the drip edging by about 1/4 inch, and secure them in place with four evenly spaced 1-inch-long roofing nails. Those top pieces would be the starter course of shingles.
Expand the middle of one whole shake using a middle vertical chalk line mark stemming from the roof peak. The bottom of the shingle tabs should overhang the starter path of shingle top pieces by about 1/4 inch. Drive four roofing nails to the shingle to hold it in place. The nails should be just beneath the shingle’s adhesive line, which is just over the shingle tabs. Use two nails at each end and one lined up with the lines that separate the shingle tabs. Create a chalk line mark horizontally along the roof, then lining it up with the very top of this very first shingle to use as a guide for placing the remaining shingles in the row. Install additional shingles along the roof to fill up in the first row of shingles.
Step up 5 inches from the base of the first course of shingles. Align a new shake in that mark, and snap a chalk line along the new shake’s leading edge to mark the place for the next row of shingles. Align the top edge of the next row of shingles with the chalk line markers, staggering, or offsetting, the joint lines between the poles together with the joint lines in the previous class of shingles. Secure the shingles to the roof with roofing nails. This technique leaves a 5-inch reveal of the shingle tabs. Duplicate this shingle application procedure until shingles reach the peak of the gazebo. As you approach the peak, the duration of each shingle row gets shorter and the ends of the shingles overhang the hairline. Fold the top of the final row of shingles above the roof peak, and nail it in place on the roof’s other side.
Cut off the excess length of shingles that overhangs the roof beam with the utility knife or hook knife, with the line where two sides meet at each hip for a guide. Put in the shingles around the remaining sides of the gazebo roof until the roof is totally shingled.
Cut off individual roof shingle tabs to use as caps along each roof fashionable, continuing the cut lines that separate individual tabs. Cut the top portion of each split piece at a small angle so that every piece is not perfectly square. That technique makes it easier for the tab part of a shingle to conceal the top portion of a preceding shingle.
Center a single shingle tab above a roof hip for a cap slice, beginning at the hip’s bottom. The bottom center of the tab should overhang the roof edge by about 1/4 inch while the surfaces of the underside shingle edge should overhang by several inches. Drive 2 roofing nails through the shingle tab just under its adhesive line. Cut the tab’s overhanging sides flush with the shingles around the remainder of the roof.
Align a second individual shingle tab above the first tab you implemented as a roof fashionable cap slice, leaving a 5-inch reveal of the very first slice. Drive two nails to hold the next tab in place. Repeat this process all along the roof fashionable up to the roof peak. Continue the identical process along each roof fashionable on the gazebo. Trimming overhanging pieces at the peak of each roof hip could be necessary, much like you trim the overhanging shingles on each gazebo side and also in the base of the hairline. Depending on the roof peak’s style, it may be necessary to put in a few shingle cap pieces in exactly the same way you capped the roof hips.
