## How are ridge caps calculated?

To find the length of ridge capping required to cover one hip, measure the distance from the ridge line to the fascia on the roof plan (here 4000mm) and the gutter overhang and multiply by the Hip Length Roof Slope Factor for 30 degrees. Multiply by 4.

## Are ridge cap shingles necessary?

Since asphalt shingles are more prone to wear and tear compared to metal roofing, it’s even more critical to have ridge cap shingles in place to stop rain and moisture from penetrating. For unique roof designs and sizes, it’s possible to cut regular shingles to create special ridge caps.

## How many feet is a bundle of capping?

ft. per Bundle ) (45-pieces)

## Can you use 3-tab shingles for ridge cap?

The ridge cap, the course of shingles on the very ridge of the roof, can be made from available 3-tab shingles. Two simple cuts create three pieces that can be used to finish the shingle project.

## How many bundles of shingles do I need for a 12×12 roof?

As a rule of thumb, there are 3 bundles to a square, assuming that you are using three-tab strip shingles. There are also 29 standard-sized shingles (measuring 12 inches by 36 inches) in each one of these.

## How many shingles do I need for a 24×24 garage?

Roof areas are measured in squares – one square equals 100 square feet of roof. To find the number of squares on the gable roof above, divide a total of 24,000 square feet by 100 (24,000 ÷ 100 = 240). This means that you will need 240 squares of shingles to cover this roof.

## Why is ridge cap important?

A ridge cap fits over the joint between these two edges to keep rain and snow out of the home. It also helps to finish off the look of the roof by creating a tightly sealed joint along the two sides. Pre-fabricated roof caps may be used when workers are installing roofing systems.

## What’s the difference between ridge cap shingles and regular shingles?

Ridge cap shingles are specifically designed to fit the ridges of roofs. That’s why they are typically pre-bent and thicker than regular roof shingles, which tend to crack when folded over the ridge. Additionally, ridge cap shingles have more adhesion and a thicker nailing area when compared to regular shingles.

## How many feet does 1 bundle of cap shingles cover?

Each bundle has 45 caps (15 full sheets w/ 3 caps each) and when installed at 6-2/3″ exposure, that will cover a full 25 feet.

## How do I calculate how many shingles I need?

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 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.

## Do you need starter shingles with 3 tab?

A lot of roofers claim you don’t need to use officially designated starter strip shingles and instead opt for using repurposed 3-tab shingles as the starter strip. Starter shingles should always overhang the eave and rake edges of the roof by about 1/4″-3/4″ to ensure adequate rain water drainage.
