How Do You Lay Out And Cut Hip And Valley Roof Rafters?
Starting with a straight line on your roof is easiest once you’ve decided on the slope. You can either measure it or take a board or two and lay them out right to ensure there’s no bumping into anything, then cut them at the same angle with a saw that suits your needs.
The rafter should be secured until the rest of the roof is installed. You can do this by nailing or screwing them in place.
You may want to take a tape measure and mark out your shingles first, then cut them from the top down at a 30-degree angle. Then lay those out with your shingles and move on to cutting hip and valley rafters for each hip section of your roof. To do so, you will need to cut through the shingle space over each hip.
How Do You Make Al Shaped Hip Roof?
A hip roof that is an “Al” shape requires that you cut the hip rafters and valley rafters to the same length but only make one angle on the rafter. Otherwise, your Hip Roof will look like a trapezoid shape instead of an “Al.”
To do this, measure each side of your roof and find the distance from each endpoint of the ridge. Measure up one side, then measure down from that same side on another line perpendicular to it. In between, have a 60-degree angle. Cut these pieces at their midpoint and nail them together for your Advant-Edge Hip Roof Al.
How Do You Measure A 4-Sided Hip Roof?
To measure a 4-sided hip roof, lay out one corner of the roof, then measure from that same point to the opposite corner. On your line, mark the distance between these two points.
Measure down from this point on a line perpendicular to it and extend that distance from that point across to mark one side of your roof (the “height” of your 2-sides square.).
For example, if you use an 8-ft measurement for the length of your 4-sides square, add a couple more feet to it, so you have room for your height measurement.
Once you have this information, simply connect these two measured lines with a straight edge and draw the corner lines through them.
How Do You Measure A Hip For A Tin Roof?
Here’s how to measure the whole roof area for installation, step by step:
Step 1: Start sketching a top-down view of your home’s roof at a 45° angle with the measured bottom of your roof valley. You’ll need to locate the triangle created by the bottom of your valley and a teepee (we used this one on our blog as an example).
Step 2: Measure the length of your roof valley horizontally (or vertically) and mark it on your sketch. Add another four feet of height to the original length, and your total will be the full length of your roof’s valley.
Step 3: Next, determine the width of the metal you’re installing and multiply this number by 3.2 to find your roof’s actual area in square feet.
Step 4: Repeat Step 3 for the other side of the roof. This will give you a total area measurement for each of your roof’s corners.
Step 5: Your final step is to measure the length and width of your roof and then multiply the end-to-end measurement by 1.1 to find out how many square feet you’ll need for your shingles.
How Do You Measure A Hip Roof From The Ground?
Measure from the face of the wall under the fascia or rafter tails to the outside border of the roof. Multiply this figure by the length of the roof from end to end, then add it to the first figure.
To find the total area of the roof on both sides, multiply the result by two, then add it to the width of the roof. The resulting sum will be the total area of a hip roof.
