  • Hiring a Pro: Tips to Follow

When hiring a pro, some tips help ensure you deal with the right people. In other words, these tips prevent you from falling victim to non-professionals.

All reputable contractors have a license as required by states. It’s also best to deal with multiple contractors by asking for quotes from at least three.

This helps you get the best possible deal you can find.

Next, it’s essential to determine if the professionals you’re dealing with are bonded or insured. This serves as protection from liability issues.

Measuring a Roof for Shingles

The roof type and complexity would determine the steps for measuring a roof for shingles.

Some of the most complex types include the gambrel and curved roofs, while one of the simplest is the single gable roof. Here, the approaches to measurement are pretty different.

However, the same principles are used. Let’s discuss;

To measure a roof for shingles, you’ll need to begin by prepping. This is followed by measuring the rake, taking measurements, calculating the area, and figuring out the required bundles.

Let’s explain:

i. Prepping for Roof Measurement for Shingles

Before measuring a roof for shingles, initial preparation is necessary. An overhead view of your roof needs to be drawn first. Here, nothing complex is required, but just an outline.

All roof planes must be covered or drawn to attach or fill in measurement values to the corresponding parts or sections of the outline.

ii. Measuring the Rake

Get your ladder set and climb up your roof using a three-point grip. It’s crucial to implement all precautionary measures to guarantee safety.

Also called the ridge, ridgepole, or apex, the rake is first measured. This starts from the apex to the edge or gutters of the roof. Having a helping hand will reduce risks and help with effective measurement.

iii. Taking Measurements

The square footage of each plane should be carefully taken. While doing this, it’s essential to consider the shapes of roof planes. Such may be square, rectangular, trapezoids, and triangles.

Each has its formula for getting a roof’s total square footage. For a rectangle, it will be Area=Length X Width. For a Trapezoid, it’s Area=[(Top + Bottom) x Height] / 2, while for a triangle, the formula to use in getting the area is Area = (Base x Height) / 2

iv. Calculating the Area

With the formulas provided, you only have to use the measurements obtained to calculate the area.

In other words, the values derived will accurately measure the roof shingles needed for your structure. This is done after taking the values.

v. Figuring Out the Required Bundles

Getting the hang of the shingle bundles required is another vital step in measuring your roof.

Depending on the type of shingle, a bundle would cover around 1/3 of a roofing square. Multiply the number of shingles by 3 to find the bundles required.

The Waste Factor

Have you ever heard about the waste factor? When measuring a roof for shingles, the idea is to have a number or estimate to work with.

While that is true, it’s essential to understand that having an exact amount of shingles based on estimations done isn’t ideal. It’s necessary to take into account the waste fact.

More shingles than the amount estimated should be ordered.

Knowing how to measure a roof for shingles is crucial, especially for DIYers. This guide has touched on the basics, including tips on finding the right roofing contractors for persons who prefer professional assistance.
