How Many Squares Are In A Bundle Of Shingles
One of the hardest home improvement jobs any homeowner can undertake is roofing projects. It is easy to see why so many leave this up to professional roofing contractors.
While this does make a lot of sense, there can still be a good reason to know how many roof shingles you need for your roof.
So you can obtain a good understanding of what you will need, here is all you need to know aboutcalculating the number of bundles and total shingles needed for your roof, regardless of who installs it.
How Many Squares Make Up A Roof
Determining how many squares make up a roof requires the roofer to take length and width measurements of the roofs surface, including all overhangs and oddly-shaped spots to find its square footage, then divide the total square footage by 100.
For example, lets say the total square footage to be re-roofed is 2400ft2. The roofer will divide this number by 100 to arrive at the final number of squares needed to re-roof the home.
2400 / 100 = 24 squares
These measurements should be done by experienced roofers, as the different parts of the roof, such as the pitch and dormers, as well as a correction factor, will need to be carefully measured and taken into consideration.

How Much Underlayment And Other Materials Will My Roof Need
Roofs not only have shingles, but also felt underneath the shingles and ice and watershield in the valleys. You can get 15 lb felt or 30 lb felt. Both types are generally $20 per roll. 15 lb felt covers 4 squares per roll, and 30 lb felt only covers 2 squares, so youll need double the amount of rolls if you use 30 lb felt.
We have some advice from a professional roofer on selecting the proper underlayment . When it comes to asphalt saturated felt paper, there is only one true 30 lb UL. It is made by Tamko and it is called Tamko Underlayment 30 lb felt. It typically needs to be specially ordered. Regular 30 lb felt is a UL 15 or 16, just as regular 15 lb felt is typically a UL 8. GAF Shingle Mate lays nice and flat and is one more Branded Component needed to meet warranty requirements.
If you have a 30 square roof and go with 15 lb felt, it will cost about $160. If you use 30 lb felt, it will cost approximately $320.
Ice and watershield underlayment is installed in the valleys of a roof for extra protection. An average roof needs about 2 rolls of ice and watershield. Each roll costs about $50, so total cost of ice and watershield is $100.
Most homeowners are having new ridge vent installed on their home now. The average home needs 60 feet of ridge vent. Ridge vent comes in 4 foot sections for $10 per section. After doing the math, ridge vent on a home costs $150.
Plan For Waste Factor
The only roof that will generate no waste from cutting is that rare simple gable whose roof length is divisible by the 3-ft. length of a shingle. Other simple gable roofs will require cut shingles at the rakes. From there, the waste factor increases with every obstruction, such as a chimney, and with every hip or valley.
Laminated shingles typically generate less waste than three-tab shingles do because you dont have to maintain a cutout pattern, but its tricky to determine exactly how many square feet of shingles you will be able to salvage. Its best to plan your order using the same waste factor that you would use for three-tab shinglesat worst youll just have a couple of bundles to return.For a simple roof, I generally figure 1 percent as a waste factor. On a complex roof with open valleys, I add 5 percent and sometimes more. Theres no calculation you can use to determine the extra shingles youll need for waste. With experience estimating jobs, youll get a feel for how many extra shingles to order.
Waste is also generated when shingles are damaged, which is inevitable when youre moving shingles around a steep roof slope and some will slide off. You may be able to salvage part of the damaged shingle, but dont count on it. You can also waste shingles when you nail them improperly and have to remove them. You may drive nails too low in the exposure or fasten one off a control line.

Find The Area Of The Footprint Of The Roof
To calculate a roofs 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 for the roof.
The calculator above can handle all of this, simply enter the length, width, and pitch, and it will determine the size of the roof in squares.
Start by measuring the roofs length and width in feet as youre standing on the ground. Remember that the length and width need to be found for the roof, not the house, so take into account that the roof overhangs the building.
Then determine the area of the roof as if it were flat. Multiply the length by the width in feet to get the area measurement.

Malarkey And Certainteed Against The World
How do the top-selling lines from these heavyweight brands stack up against the best shingles from OC, GAF, and top manufacturers? While an exhaustive comparison would exhaust us all, heres a brief look at how the CertainTeed Landmark and Malarkey Legacy shingles compare with the best-selling architectural shingles from other leading brands.
Owens Corning Duration The Duration family of shingles covers a lot of territory more like CertainTeed Landmark than Malarkey Legacy. This is how OC has chosen to market this line or rather 8 lines of shingles all under the Duration umbrella.
Four lines offer solar reflective shingles that meet CRRC standards. Two, Flex and Storm, use polymer-enhanced asphalt to achieve a Class 4 impact rating equal to Legacy NEX and Landmark ClimateFlex lines.
Warranties are very comparable including Lifetime warranties on most shingle lines.
The bottom line is that OC gets better ratings on many platforms when compared with CertainTeed and Malarkey.
GAF Timberline HDZ are the closest match from GAF to the Legacy and Landmark lines. GAF claims this is the best-selling shingle in America, and thats probably true.
In short, you get less variety in shingle lines and styles with GAF, but the Timberline HDZ is pretty close in overall quality maybe just a step behind except when it comes to windy conditions.

Figure Out The Area Of The Shed Plus The Overhangs
Determine the squre footage of the shed foot print by measuring the length and width of the shed including the overhangs. For example, if you have a simple 12 foot by 16 foot shed you add the overhangs to those dimensions. If the overhangs are 1′-0″ then you have 2′ extra each dimension. 14′ x 18′ = 252 sf. flat.
The Definition Of Roofing Square
In the roofing industrys terminology, a roofing square or per square is 100 square feet. A 100 square foot area of roof makes a roofing square. However, a square is not 100 square feet of roofing material. It is the amount of material needed to cover 100 square feet of roof.
While you may have heard that you can use simple geometry or an online program to calculate the number of roofing squares on a roof for the overall price of replacing your roof, a simple mistake can be costly. It can also cause a shortage of material that will mean delays.
For example, a complex roof with hip-end sections and gable ends may be difficult to accurately estimate even if you prepare a detailed drawing.

Roofing Square How Contractors Measure And Price Roofs
Roofing square is the most common measurement unit used by roofers, as well as contractors from many other trades. It greatly simplifies communication between architects, contractors, roofing manufacturers, suppliers and even clients. Its much easier to say 25 squares than 2507 square feet, and there is less information lost in translation.
How To Measure A Roof For Shingles
The most accurate calculation of the number of shingle bundles needed is climbing up to the roof and measuring each roof plane on the roof.
If all roof planes are rectangular, you can quickly multiply their length by the width of each plane. Add them together, and you have your square footage for the whole roof.
It does become more difficult when you have a complicated roof, and the planes are of different sizes.
In some cases, for safety reasons, it may be necessary to take measurements from the ground.
Measure the length of the building and estimate the possible overhang of the rake edge. For widths, climb up a ladder and measure from the roof ridge to the eaves with a rigid tape.

Square Used Outside Of The Roofing Industry

Heavy industries, such as industrial pool lining companies, also price their work by the square. Even landscaping contractors use squares, if lawns had regular shapes, but because most lawns have rather weird shapes, I have no idea how much they charge to cut one square of grassPainters also use squares it is the same as in siding, only the job is much dirtier and pays less nominally speaking.
