Then your first shingle goes on the side you are going to cut.

How to shingle an angled roof.

Nail each side of the shingle to each side of the ridge just below the shingles self sealing strip. Cut the shingles so that both edges of the upper overlap part have an inward angle. You want to lay the shingles from the bottom to the top of the valley. Install new flashing metal.

At a very low slope any water on the roof whether rain water or snow melt drains very slowly and there is a risk of lateral water movement. Asphalt roofing shingles simply rely on the force of gravity to shed water from rain or snow melt. Place the first shingle end flush to the edge of the roof. If the roof shingles and all accessory roof components are arranged and overlapped with this in mind the roof should successfully shed water.

Shingles on a steeper roof also tend to weather at a slower rate due to their favorable angle to the sun s rays. Start by overlapping a starter from both sides of the valley at the bottom. A couple of weeks ago we published a two part series showing how a local roofing contractor shingled a roof with architectural shingles. To secure each angled shingle i drive one staple or shingle nail at least 2 inches above the lower edge of the next shingle course and into the top corner of the step flashing.

Why is 2 12 the minimum. To cut your own just cut down multi flap shingles into individual shingles. The next one goes on the low side. Overlap each row at least 3 to 4 inches.

Start by laying asphalt felt or other underlayment over the roof. If you live in an area with inclement weather you should consider using a special ice and water protector. Using your staple gun secure the felt to the roof. 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.

Weave and cut the valley on the highest side of the roof. Understand the physics of how a sloped shingle roof works. Another key to having the roof drain effectively while making this detail look professional is to create a consistent gap between the roofing and the cedar shingle siding.
