How To Seal A 3 Tab Shingle Roof

Two simple cuts create three pieces that can be used to finish the shingle project.

How to seal a 3 tab shingle roof.

A layer of sand is added to the base of the shingle which is then fed into a press to embed the granules. Drive a nail at one end first then drive the others. Install the drip edge over the gable end felt and under the eaves felt. To protect against wind and hail damage the sheet is covered with a strip of sealant.

Typically 10 by 8 inch 253 mm x 203 mm flashing is chosen. Do the same with the next shingle continuing this step until you get to the far edge of the ridge. Those 8 inches are more than enough to cover the exposure of typical shingles. Cut your last shingle on each row to size repeating all the way to the ridge.

Granules are made from mined rock that has been crushed. To give a shingle its color texture and protective coating granules are added. Roll out and staple down roofing felt in overlapping rows. Nail the shingles with no tabs such as precut pro start shingles and apply asphalt cement from a caulk gun in many dots along the drip edge under the edge then press the tab less shingles down onto the line of asphalt cement dots with adequate spaces between the dots.

For example 3 tab shingles usually have a 5 5 8 inch 143 mm exposure. Typically 10 by 8 inch 253 mm x 203 mm flashing is chosen. Attach the starter strip. If the roof shingles and all accessory roof components are arranged and overlapped with this in mind the roof should successfully shed water.

Attach and align shingles to attach a 3 tab shingle align it with the layout line and drive nails 1 2 inch above the cutout slots including the half slots at each side. If you are using a power nailer drive nails by squeezing the trigger and bouncing the nailer s tip onto the shingle. In the dictionary to shingle is. There are some simple techniques to follow when attempting this project.

For the first row of shingles called a starter course or strip you cut the tabs off three tab shingles and apply them with the self sealing adhesive strip facing up along the eave. A continuous bead of asphalt could trap condensation or windblown water under the roofing at some point. Once you ve reached the ridge bend the shingle over the ridge so that each side is equal and nail it into place with a single nail on each side. Make sure this row has a slight overhang 1 4 to 3 8 in beyond the drip edge.

Asphalt roofing shingles simply rely on the force of gravity to shed water from rain or snow melt. The ridge cap the course of shingles on the very ridge of the roof can be made from available 3 tab shingles.
