How do you layout a roof for architectural shingles?

Lay one row of shingles, starting from the lower left corner of the roof. This row should project half an inch (1.27 centimeters) over the eaves. Nail down the shingles as you go along. Lay the next row of shingles, directly on top of the first row, making the row two tiles thick.

Apply the first shingle of the first course in the middle of the hip roof. Install the second shingle to the right of the first shingle.

Similarly, how far should shingles overhang drip edge? The edge of the shingles should hang over a roof between an inch and an inch and a half — or between a half inch and three-quarters of an inch if drip edge flashing is installed. Too much overhang and the shingles could blow off in high winds; too little can allow water to seep into rake or fascia boards.

Just so, can architectural shingles be used for ridge cap?

Some roofers will cut shingles into pieces and use these pieces for the hip and ridge cap, regardless of which shingle is being used on the roof. The thicker Cambridge shingles are not designed for ridge caps. They do not lay flat and some may crack or break when you bent them over the ridges.

Does flashing go over or under shingles?

This is true no matter what type of roof-covering material is installed. Flashing should overlap the roof-covering material, but on asphalt shingle roofs, for aesthetic reasons, the part of the headwall flashing that extends down over asphalt shingles is often covered with a course of shingle tabs.

Do you install drip edge before tar paper?

The best way is to install the roof drip edge only along the eaves first, then place ice-and-water barrier (in the snowbelt) or felt paper (underlayment) over the drip edge. This lets any water that gets on the roof run down the underlayment and over the drip edge.

How do you reshingle a roof?

Steps Remove old shingles. Remove leftover debris from the roof. Secure loose boards, and nails that may have worked up (and are sticking up). Cover large holes in boards. Install the roofing felt. Install the drip edge. Secure new shingles. Secure the ridge cap.

What are the lines on roofing felt?

Before laying roof felt, all rotten decking must be replaced. Drip edges on the eaves, any valley liners and all flashing should be installed before the tar paper is laid. Chalk lines should be snapped 33 5/8” above the eave line. After this, lines should be snapped every 34” as you move up the roof.

How do you cut shingles for a ridge cap?

Cut the necessary number of pieces for the ridge cap from the 3-tab shingles. As described earlier, use a utility knife and straight edge to cut at the slots in the shingle, effectively creating three equal-sized pieces of ridge cap from one 3-tab shingle.

Where do you nail shingles?

NAILING: Use galvanized (zinc coated) roofing nails, 11 or 12 gauge, with at least 3/8″ diameter heads, long enough to penetrate through plywood or 3/4″ into boards. Use 4 nails per shingle placed 6-1/8″ above the butt edge, 1″ and 13″ in from each end and 1/2″ above each cutout.

How do you put roofing felt on a hip roof?

The basic idea is to install the asphalt-treated felt in such a manner that the roof will shed water. Wrap felt over hips. Wrap felt over hips. Start at the bottom of one side of the roof at the right or left edge. Position the first row of roofing felt flush on the bottom with the edge of the gutter apron.

Do you overlap shingles on a hip roof?

The very last shingle that is placed on the hip roof should be affixed with asphalt roofing cement in addition to nailing. Start from the bottom edge of the ridge and secure each shingle with 1 1/2-inch nails. Overlap them as before and continue until you reach the top.

How much should shingles overlap?

Shingle manufacturers specify a minimum overlap, usually in the range of 4 inches to 5 inches. On this roof, the minimum overlap specified by the manufacturer is 4 inches, and the recommended overlap is 6 1/2 inches.
