Your last shingle is an exposed shingle.

How to shingle a roof up to a wall. This project guide is a combination of those two articles and it covers replacing the existing roof decking installing underlayment and ice dam protection laying the first row laying shingles in the field flashing ridge shingles and vents and more. The installer tacked a row of asphalt shingles to the wall caulked their top edge and hoped for the best. The wall leg of the kickout should be applied over the housewrap cut a 2 ft square piece of housewrap and tuck one edge into the horizontal cut the same one the first piece of housewrap was slipped into and up under the housewrap on the wall by at least 5 in. Roof planes that butt against vertical walls at the end of the shingle course are protected by metal step flashing at least 125 mm high and 125 mm wide 5 high and 5 wide.

Install the next shingle approximately 2 3 past the seal strip of the first shingle. Continue laying your shingles horizontally up the roof. To install the roof wall flashing above the builder bent the top edge of the flashing into a 90 degree lip about 2 cm in width. If you hit a stack vent or chimney interlace the shingles with the flashing to allow water to run down the roof.

Because most roof flashing is required to extend up the wall a minimum of 4 and some a minimum of 5. When you reach the peak either bring the ridge edges together with a ridge capping layer or cut regular shingles into 3 tabbed equal pieces and bend them so they fit on the roof peak.

The stair step method tends to spread and mix the bundles better. Use sticky back ice and water shield as underlayment where ice dams or leaf and twig dams are likely to build up and at valleys and where the roof ends at a wall wide metal flashing may also be used there. Now install the kickout flashing and step flashings up the roof as needed. Keep this up until you reach the other end of the peak.

A couple of weeks ago we published a two part series showing how a local roofing contractor shingled a roof with architectural shingles. Most simply use a nominal 6 piece of lumber. Prevent shadowing by checking to make sure all the bundles have the same lot number on the wrapper not just the same color. The roof flashing is then placed up behind this through the wall z bar flashing on the outside of the vertical blocking backing material.

Use tin caps under staples if the roof may be exposed to wind before shingles are to be applied. If the adjacent shingles come from other bundles that are a slightly different color the roof may look patchy even striped. Place the first shingle end flush to the edge of the roof.
