How many bundles of shingles can be found in a 2,000 square feet area?
How many bundles of asphalt shingles, rolls of felt, and squares of roofing material are needed for a new roof can be calculated.To get an estimated material cost, add the price per square of materials.
The first thing to consider is the roof's size so accurate estimates can be made.
In the U.S., roofs are measured in square footage, and roofing contractors typically quote projects based on the size of the roof in squares.Gathering the size of the roof in squares and square footage is the first step.
To calculate a roof's dimensions, you need to measure the roof as if it were flat, then account for roof pitch, calculate square footage, and finally determine how many squares of material are required.
The calculator above will determine the size of the roof in squares by entering the length, width, and pitch.
As you stand on the ground, measure the roof's length and width in feet.The roof overhangs the building so it's important that the length and width of the roof is found.
The area of the roof should be flat.To get the area measurement, divide the length by the width in feet.
The overall roof area can be found by accounting for the roof's pitch.The rise over the 12-inch run is the pitch of the roof.To find the pitch of your roof, use our roof pitch calculator.
Next, divide the footprint of the roof by the pitch to find the overall roof area.A 4/12 pitch roof is 100 square feet.
It's important to find this measurement to estimate the amount of material needed accurately, because roofing contractors estimate projects and materials by the square.A square is simply a square of roofing.100 square feet of roof is what this is.
To find the squares, round up the roof area by 100.If the roof is 1550 square feet, it is 16 squares.
Although roofing projects are estimated and sold by the square, roofing material is often not sold in 1 square increment.
Three bundles of shingles are needed for each square.For a standard 3-tab style, the price is around $50-$75 for an upgraded architectural style.
Since transportation is a major cost factor, expect prices to vary by location.Some premium products can weigh over 100 pounds per bundle, so consider delivery of materials.
The felt is sold by the roll.The average roll of 15-pound roofing felt covers 400 ft2 or 4 squares, while the average 30-pound roll covers 200 ft2, or 2 squares.
There are rolls of felt that are long for 15# and short for 30#.Consider other options, such as rubber or tar products.
Any roofing project will require nails.Four nails are needed per shingle.Some types of shingles may need more.Assuming four nails per shingle and 80 shingles per square, 320 nails will be needed to install a square of standard 3-tab shingles.
The roof's edge will need to be protected from rot, vents, and other materials such as flashing or caulk.Depending on their condition, the fascia boards may need to be replaced.
Find the perimeter of your roof in feet to find the length of the boards you need.
It is important to order extra material if you want to accurately estimate materials.To make sure you have enough material, account for about 10% overage on your project.This is important for materials with long lead times.
If you want to understand material and labor costs, we recommend getting free roofing estimates.
When installing a new roof, there are other factors to consider.There are costs for installing a new roof.Many localities require permits and inspections for roofing projects, so be sure to consult local building codes for more information.
It is a good idea to remove old materials and dispose of a large amount of waste.Order a dumpster for the project.
