If you’re thinking about installing solar panels on your roof, you’re probably wondering if your type of roof is suitable and whether solar panels will affect the roof. Let’s look at some solutions to the many questions you may have about installing solar panels.

Do I Need To Replace My Roof Before Installing Solar Panels?

The condition of your current roof is the most important element to examine. If you plan to install solar panels on your roof, it should be relatively new and in good condition.

If the roof is installed longer than five years, consider having it inspected by a roofing specialist such as https://www.loaconstruction.com/. You should usually replace it before adding solar panels if it is towards the end of its expected warranty or in bad condition.

This assures that the solar panels, which carry the weight of the second layer of shingles, will be able to support your roof. Furthermore, because most solar panels last 25-30 years or longer, you need a roof with a long lifespan as well.

Is Solar Panel Installation Possible on My Roof?

The good news is that solar panels may be installed on almost any style of roof. Aside from the roof’s age and condition, the following factors influence its solar panel compatibility: material, shape, size, pitch, and orientation.

Let’s take a look at each of these aspects in more detail.

Roofing Materials

Most roofing materials, fortunately, can handle a solar panel installation without causing damage to the roof. Solar panels work well with asphalt shingle roofing, which is very easy to install.

Solar panels are also well-suited to tile roofs, making them simple to install. A standing metal roof is best for solar panels. Without drilling into the roof, the standing seam enables a simpler and less expensive installation.

Wood and slate roofs are examples of roofing materials that aren’t great for solar. For one thing, because these roofing materials are brittle, solar panel installers are unable to walk around on the roof as they would usually. 

This makes the installation process more laborious and, as a result, more expensive. Another issue with solar panels on a shingle roof is that they can be a fire hazard.

Roofing Pitches

Your roof’s pitch, or angle, is also something to think about. The vertical rise divided by the horizontal run determines the roof pitch. The best angle for a solar panel, according to most experts, is 30 degrees.

Contractors may not be able to securely install the panels on steeper roofs, which is a problem. Flat roofs will necessitate the use of brackets to angle the panels, which can be costly. The manner solar panels are mounted on a flat roof is also influenced by the roof’s material.

Roof Shape, Size, and Orientation

The form and size of your roof might also influence whether or not solar panels can be installed on it. The average household solar system in the United States is five kilowatts, requiring at least 300 sq ft of roof space. A wide, square roof is the optimal shape and size for solar panels because it allows for easy installation.

Because roofs come in a variety of shapes and sizes, you should consult a contractor like https://www.loaconstruction.com/ to determine whether solar panels would be a good match and how much of your roof surface can be covered by panels.

When solar panels are facing south, they are most effective. You can also request that your contractor install the panels on a rack so that you can modify their orientation.

Final Thoughts

Before you buy solar panels, have a professional come out and inspect your roof for condition and compatibility. It’s also worthwhile because of the return on investment.
