How to Estimate Shingle Counts for Covering Roofs

One of the most regretful things one can do during construction is to calculate wrongly. If that happens, you should expect to see a shortfall of materials thus causing a delay in your work. What is more, you might be unable to find money to top up whatever is missing. For this reason, it’s important to take great care when calculating materials. More importantly, learn how to do your estimations, especially where shingles for covering roofs are concerned.

Below are a few thoughts to assist you to handle this matter well.

Calculating the quantity of shingles

When you head to an ironware store to buy roofing materials, specifically shingles, you will find them arranged or sold by the bundle or per square. A single square has enough shingles for covering a roof of up to 100sq.ft. So, your first step should be to calculate the roofing area that needs covering. You should calculate the area after stripping it off the previous materials. To do this, you would need to employ either:

a) Measurement method

Find your way to the roof with your measuring device. Once there, measure each of the roofing planes. Your task would be much easier when dealing with planes that are shaped similarly. Do not dash to the roof without any safety equipment, especially for one that’s too slippery. If you lack safety equipment, your best option would be to do the measuring from the ground. Take your time to avoid making costly mistakes.

b) Count the sheets method

This method works well with exposed sheathing. In fact, one of this method’s greatest advantages is the fact you can do the counting from the ground. What is more, this method is faster than calculating by measurement. However, this method has limitations. One, it is only applicable on roofs sheathed with specific structural panels, which in this case is 4ft by 8ft. At this stage, you would be right in rushing to the store to order your shingles.

When ordering the shingles, take cognizant of the fact that some of them will suffer damages and breakages during installation. Therefore, buy some extra shingles to account for this. It’s better to have a few left, once installation is complete instead of running out of shingles to use in covering the roof. You will also need extra shingles for capping hips and ridges. Wastes occur while cutting shingles. Wastes would depend on the amount of obstructions and hips on your roof.

There is no harm in contacting a trained roofer to do this work for you if you think it’s too much for you. In fact, a professional roofing specialist will limit or eliminate the likelihood of making wrong calculations thereby saving you huge sums of money and time. The thing to remember in all this is to buy more than you need to account for cuttings, wastes, and damages. Avoid limiting yourself to the exact number that your roof needs.
