Calculate the area of the gable using the formula: gable area = width x (height / 2). Using the example width of 25 feet and gable height of 10 feet, the surface area of the gable is 125 square feet: 25 x (10/2) = 125.
How do you measure a gable roof for shingles?
Roof surfaces are measured in “squares”. A roofing square is equal to 100 square feet of the roof. To determine the number of squares on the gable roof example in this post, divide its total of 2400 square feet by 100 (2400 ÷ 100 = 24). This means you would need 24 squares of shingles to cover that roof.
How big is a gable roof?
Common Peaks Are 60 to 84 Inches The most common pitches for houses are 5/12 and 6/12 and the most common runs are 12 or14 feet, for roofs 24 or 28 feet wide. A 12-foot run has a peak of 60 inches with a 5 pitch, 72 inches with a 6. A 14-foot run would have comparable peaks of 70 and 84 inches.
How do you calculate starter shingles?
Determine the number of shingles to order for starters by measuring the length of the eaves and rakes, then round up to the nearest foot and divide by three (the length of a shingle).
What is gable roof type?
Gabled roofs are the kind young children typically draw. They have two sloping sides that come together at a ridge, creating end walls with a triangular extension, called a gable, at the top.
How do you calculate the area of a sloped roof?
Determine the area protected by the sloping roof by multiplying the length of the roof by the width. The result is the area covered by the sloping roof. For example, a single sloping roof covering a house 30 feet long and 20 feet wide covers an area of 600 square feet — 30 x 20 = 600.
How do you measure a roof online?
Step Two: Begin Measuring Your Roof Frame your home back to the top shot. Click the ruler icon on the left side of your screen. Switch the unit of measurement to feet. Click on a starting and stopping point, and you’ll get an estimated measure of distance. Start logging in your measurements.
How do you calculate the square Metres of a roof?
To calculate your roof area, simply multiply your roof length by your roof slope height, and multiply this by two. This should give you the total area of your roof, not accounting for a chimney or other sections of your roof not covered by tiles.
How do you measure a hip and valley roof?
To measure the length of a hip roof you will need to hook your measuring tape up to the eave at the ridge rafter, run it up all the way up the ridge rafter, over the length of the entire ridge, and then back down the opposite ridge rafter down to the opposite eave.
How do you measure the length of a truss?
Truss count = ((roof length * 12) / 24) + 1 The simplest form of this equation is to take the length of your roof and divide it by 2. For example, if your roof is 40-feet long, it will need a total of 20 trusses.
How do you measure a rafter?
Note that rafter length is measured from the tip of a plumb cut at the top end of the rafter (ridge cut) to the building line (shown as a dotted red line in the Section/Elevation below). Rafter length does not include the rafter overhang.
How do you calculate rafter length and Birdsmouth?
On the rafter, you want to cut, measure its overall depth, and divide it by 3. Using this figure, measure and mark two points on each side of the vertical line, which indicates where the birdsmouth will be cut.
What length should I cut my starter shingles?
Cut 12 inches (30.4 centimeters) off the length of the first shingle that you lay. Then lay down whole tiles to the end of the row, trimming the last shingle so that it fits correctly.
How do I figure out how many bundles of shingles I need?
The most accurate way to calculate how many bundles of shingles you’ll need is to get up on the roof and measure each roof plane. If all the roof planes are rectangles, you simply need to multiply the length times the width of each plane to get the square footage; then you will add up the square footage of each plane.
How many bundles of shingles do I need for a 12×12 roof?
Bundles. Asphalt shingles and most other roof shingles are typically available in bundles. For each roofing square or 100 sq ft, you’ll need three bundles of shingles.
How does a gable roof look like?
A gable roof is a type of roof design where two sides slope downward toward the walls – and the other two sides include walls that extend from the bottom of the eaves to the peak of the ridge. Most residential roofs are sloped, so water runs down the slope into gutters or off the eaves.
