How many bundles of shingles in a square?


If you’re a builder, then you know that one of the most important parts of your job is calculating how much material you need for a project. When it comes to shingles, this can be a tricky task – after all, there are all sorts of different sizes and shapes that they come in. Luckily, we’ve put together a quick guide on how many bundles of shingles you’ll need for a square. Just follow the steps below and you’ll have everything you need in no time!

Estimating the number of bundles of shingles needed to cover a square of roofing

Estimating how many bundles of shingles are sufficient to cover an area of roofing requires careful calculation. Depending on the overall dimensions, pitch, and type of shingle chosen, a square of roofing could require anywhere from two to four bundles. To accurately gauge how many bundles are needed, professional roofers take into account factors such as the number of feet in a square, how many tabs make up the shingles per bundle, how far apart nails should be placed for optimal fastening, and how steep the angle of the roof is. When all these elements are factored into a final estimate, it will ensure that enough material is purchased for the job.

The average size of a bundle of shingles

A bundle of shingles typically contains enough material to cover approximately 33.3 square feet of roof space. Depending on the type and size of shingle, bundles can range from 25lbs to 80lbs, with three bundles needed for one square in most cases. Each bundle comprises a number of individual shingles, generally between 33 and 37 per bundle depending on the size and design. As bundles are designed to help installers with their work efficiency and accuracy, it is important that users adhere to precise instructions regarding the amount of bundles required for a given area. Taking into account the average size of bundles when estimating roofing materials requirements will help contractors accurately plan and manage projects, saving time and money at a crucial stage in the process.

How to measure your roof to calculate the number of bundles needed

Measuring your roof accurately is an important step when determining how many bundles of shingles you will need. It is a relatively straightforward process and begins with determining how many square feet are in each plane of the surface, which is measured by multiplying the length times the width. To calculate how many bundles of shingles you will need, you must divide your total square feet by how many bundles of shingles are in a square (the exact number may vary). Be sure to round up to estimate how much material to purchase, as some wastage should be expected. With careful measurement, you should have no problems accurately calculating how many bundles of shingles you’ll require for your roof.

Tips for accurately estimating the amount of shingles needed

First off, make sure to accurately measure the roof so that you have the correct square footage. When eyeballing measurements can make it easy to miscalculate, using a tape measure helps ensure accuracy! Secondly, consider standing heights and take into account over-lapping shingles to provide enough materials for two courses at least; this will help ensure you don’t run out of material mid-way through the job. Lastly, always add 10% extra material when purchasing in case there are cuts and imperfections. This will make sure you don’t get stuck in a situation where you run out of materials or are unable to complete your work on time! With proper measure and planning, accurate estimates can easily be made to ensure your projects go smoothly.

What to do if you have leftover shingles after completing your project

Completing your roofing project is an accomplishment that requires planning and hard work. If you find yourself with leftover shingles after completion, you can contact a local building supplies store to see if they have a re-stocking policy for unused materials. Additionally, Home Depot offers a sustainability program called Re-Nest which allows customers to do exactly that – recycle their extra tiles and materials from home renovation projects into the hands of other customers in need. It’s important to remember that every effort at reducing waste helps improve our environment and keep valuable resources circulating through our neighborhoods.


Although it is important to order the correct amount of shingles, it is also helpful to have some leftover in case of any mistakes. If you do end up with extra shingles after completing your roofing project, there are a few things you can do. You can either store them away for future use or donate them to a neighbor or friend who may be working on a similar project. No matter what you choose to do with them, make sure that you put them to good use and avoid having wasted money and materials. Thanks for following along as we walked through how to estimate the number of bundles of shingles needed for your next roofing project.
