How to make sure your roof is ready before installing solar panels

It’s an exciting experience when you finally decide to go solar. After much research, you have determined that you want to invest in solar panels. He is so excited that he has already started looking for solar installers in his area. Still, one small question is currently holding you back from going solar: “What else do I need to do before I ask for a quote?”

We suggest checking to make sure your roof is as ready as you are for a solar panel installation. There are three important questions to consider before going solar:

• How is your roof?

• What is the state of your roof?

• How much shade does your roof receive throughout the day?

Your answers can help you determine if it’s time to get quotes for solar panels. Let’s dig into each question, shall we?

How is my roof?

A quick inspection of your roof is a great first step in determining if you are ready for a solar panel installation. There are three main factors you should consider:

• The age of your roof

• The roof material

• Potential obstacles for solar panels

roof age

The older your roof is, the more likely it is that you will need to do some work before investing in a solar panel. If you will need to replace your roof within the next 10 years, it is best to replace it before installing the solar panels. This will save you from having to remove and reinstall them when the roof is replaced.

roofing materials

While solar panels are commonly installed on metal and asphalt roofs, some roofing materials, such as slate and Spanish tiles, require more care when installing solar panels. If your roof is made of a delicate material, you should speak to a professional roofer for a recommendation on mounting panels to your roof.

potential obstacles

Solar panels must be placed in straight rows. This means that obstacles such as vents and dormers can limit the number of panels that will fit on your roof. A good solar consultant can potentially design around these obstacles, but it can still affect your overall solar potential.

What is the condition under my roof?

Depending on the condition of your roof, you may need to replace it before installing new panels. Inspect your roof for the following signs:

• Damaged beams or trusses

• Leaks or stains in the attic or on the walls

• Mold

• Dark “dirty looking” spots on the ceiling

If your roof shows any of these signs or hasn’t been replaced in the last 10 years, consider getting a roof repair estimate from a professional. Compare prices and see what you can find. If the area where you want to install panels is inaccessible, refer to your house plans for your roof structure.

How much shade does my roof have?

Shade from trees and other buildings can limit output from your system. Because of this, it’s best to avoid installing panels in shaded areas on your roof, if possible. If necessary, trees can also be pruned to optimize the unshaded area on your roof. Use Project Sunroof to see an estimate of how much sunlight your roof sees each year and which areas of your roof would be best for panels.
