#METAL ROOF PATIO COVER INSTALL#

Today we install metal roofing with a flat profile with ribs, unlike the round corrugated roofing of years past. The metal roofing is best attached with screws with a rubber washer. I estimated the coverage and screws on 36' exposure with ribs spaced at 9' apart. The metal roofing comes in various widths and gauges. If you prefer to cut the lengths yourself, cut off the end under the flashing, at the top. Order the metal roofing pre-cut to 13'-6 '.

Install the 1x10 fascia board over the box joist, flush with the top of the 1x4 on three exposed sides. Nail the 1x4s onto each joist with 2 - 2¼' common nails. Make all joints on the center of the joists and stagger the joints.

Install the 1x4 strapping at 2' centers starting at the eaves, as shown on the ceiling plan. Nail the box joist on the end of the joists with 2 - 3' common nails into each joist. These are 1½' long and the same gauge as a 3' common nail. Nail through every hole in the joist hanger with 1½' hanger nails. Install the joist hangers around the remaining 2x8s on the ledger. Toe-nail the joist into the ledger with 4 - 3' galvanized nails and into the beam with 2 - 3' galvanized nails. Now move the tape to this mark and continue to mark and place an X in the same manner at every 16' mark on your tape, until you run off the 2x8. Start at the left end, measure 15 1/4' and place a mark with an X on the right of the mark. Layout the ledger and beam at 16' centers. The JoistsĬut the 2x8 roof joists according to the detail, place any crown on the board at the top of the board. Nail the center scab to each side of the beams. Cut 6 scabs as shown in the detail and nail them in position on each side of the joint at the post and beam. Place the beams on top of posts, toe-nail them to the top of the posts and together. Place the posts into position and temporarily brace them up to each other and to a 2x4 stake in the lawn with the 1x4s. Cut the beams 10'-0', making the joint in the center on a post. The beams are 2 - 2x10s laminated together using the same size nails fastened at 16' apart, top and bottom. The posts are 2 - 2圆s laminated together with 3' common coated nails, cut at 80' long. The left and right joist hanger is bent around the end of the ledger and nailed to it since there is no room on the face of the ledger as for the other ones. Once the top of the ledger is determined, snap a chalk line or mark a level line along this height to use as a reference for where the ledger will go. Drill the ledger out 3/8 and drill the backing out 3/16. Make sure the lag screws go into solid wood, either the existing box joist or wall studs. The roof joists are going to be attached every 16' as well as the lags, so start the first row of lags in 8' from the end, so they won't conflict with the joist hangers. If the low end is at 80', the minimum the high end should be at is 9'-8'. The slope of the roof should be at least 3' rise per foot of run. The ledger is attached to the house studs or box joist with 2 - 3/8x4' lag screws, (about 1½' from top and bottom) at every stud or 16' along the board. You want the ledger installed as high as you can, but should be just below the drain or gutter of the existing roof, allowing for the 1x4 and metal roofing, which is about 1½'. 32 - 3/8x4' galvanized lag screws with flat washers.3 tubes butyl caulking if less than 3/12 slope.The Instructions include the following topics: The List of Materials include materials for all the parts required to complete the project including: the ledger and fascia, joists, posts, beams, strapping, fascia board, sheet metal roofing, screws, caulking, flashing, joist hangers, lag screws and nails.
