Setting Upwardly Roof Jacks
Working from roof brackets and staging planks is the safest and virtually efficient way to shingle a pitched roof.
Roof jacks provide safe platforms on sloped roofs. They attach to the roof with nails, only don't use roofing nails; although the heads are broad, roofing nails are short, their shank diameters are modest, and their heads popular off easily. Apply 10d to 16d mutual nails and drive them through the roof sheathing and into the framing (run into the photo). Don't rely on nails driven just into the roof sheathing because they're likely to pull out.
Space the jacks near 6 ft. to 8 ft. apart horizontally. Plan the jack positions so that ane falls inside 1 ft. of the ends of your staging planks. Besides call back ahead to avoid placing jacks where the joints betwixt shingles and cutout slots will occur in the course immediately above.
Roof jacks have a long zipper strap with three or 4 teardrop-shaped holes or diagonal slots to drive nails into. The shape of the holes or slots permits you to remove the jacks afterwards without removing the nails: Just tap the jack upward and the nail heads volition exist released. To permit the jacks to slide upward during removal, be sure to let them hang low enough when you lot install them; otherwise the plank support leg will trample the butt edge of the shingle.
The backs of the triangular-shaped jacks will rest on the exposure portion of the shingle form beneath. With all the motion the jacks will absorb as you walk on the planks set on them, the backs tin dig into or scuff the granules on the shingle surface, or worse they can cut through the shingles. For protection, identify a piece of bit shingle between the dorsum of each roof jack and the roof shingle. You tin also use pieces of forest-siding shingles as a cushion.

Once you have a row of roof jacks in place and ii courses of shingles applied above them, carefully lay staging planks, not dimensional lumber, beyond the roof jacks. Full-cut ii×8 or 2×10 planks fit roof-jack back up arms pretty well. Every bit you lay the planks, be sure you don't slam them in place because y'all may pull the nails out of the jacks. Overlap the ends of the planks by ane ft. to ii ft., making sure the lap occurs over a roof jack. To concur the planks fast, drive nails through the holes in the turned-up ends of the support artillery and into the edges of the staging planks.
THINKING AHEAD: As you feel yourself getting close to your vertical achieve limit when shingling, install a row of roof jacks and employ two more than courses of shingles above the jacks. This way you won't take to curve into an awkward position when y'all start working on the next level in a higher place. Yous'll outset working ane ft. above the plank.
Setting Upward Jacks around Shingles
Sometimes yous'll realize that you forgot to install a row of roof jacks and you've exceeded your achieve limit. You can still install the jacks beneath shingles that are already installed. Exercise this by lifting the exposure portion of the shingle where you desire a jack, sliding the leg below, and advisedly driving nails through the holes. It may take an extra prepare of hands to hold the shingle upwardly while yous hold the jack and drive the nails. Be careful not to hitting the upturned shingle butt when swinging the hammer.
In common cold weather, shingles won't bend up without neat. In this case, you lot may be forced to drive nails through the face of shingles to attach roof jacks. Earlier doing this, place shingle scrap beneath the jack-nailing holes to protect the shingle beneath. When you remove the roof jacks, pull the nails and slide a piece of metal flashing coated with roof cement beneath the shingle nether the holes. Utilize small dabs of cement to each hole on the shingle exposure, then scrape off colour granules from a scrap shingle and printing them into the cement. This volition seal and hide the harm the roof-jack nails acquired.
Work SMART: Be aware that your toes, tools, and materials stacked on the staging planks can easily bruise the surface of the shingles directly behind the planks. As you walk along the planks, they will flex. Anything touching the shingle surface can abrade information technology equally the planks move upwards and downward. The problem is worse in warm weather when shingles soften.
