How To Shingle A Single Slope Roof

You can measure the roof slope on the bottom side of the roof deck at an easily accessible point such as the rake using a tape measure and simple geometry.

How to shingle a single slope roof.

Asphalt roofing shingles simply rely on the force of gravity to shed water from rain or snow melt. A continuous bead of asphalt could trap condensation or windblown water under the roofing at some point. Lay the last ridge cap shingle in the center of the shed roof on top of the exposed adhesive portions of the two center ridge cap shingles. A couple of weeks ago we published a two part series showing how a local roofing contractor shingled a roof with architectural shingles.

Roof pitch refers to the measurement of the slope of a roof and you express this as a ratio. Apply sealant over exposed nails on the last strip. Here s how to shingle the top edge of your shed roof. Although there s isn t any standard pitch of a roof used on all kinds of sloped roofs you can determine the range of pitches by using a roof angle calculator and by considering factors like the local climate and roofing materials.

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. Understand the physics of how a sloped shingle roof works. Use more sealant along the top edges of all shingle strips. If the roof shingles and all accessory roof components are arranged and overlapped with this in mind the roof should successfully shed water.

Secure the last ridge cap shingle with four nails at the corners of the shingle and cover the nail heads with roofing cement. Alternatively there are smart phone apps that can help but shingle manufacturers distribute convenient pitch estimator cards which provide a quick way to ballpark the slope. 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. However there are a few key differences.
