What is the best way to go solar? What do you need to consider?

Whether or not you are a homeowner planning to install solar panels or a company looking to carry out a solar installation, the confusion around the ‘do I need to replace my roof for solar panels’ question may prove to be complicated.

Need some clarity? Here’s the definitive guide to figuring out if you need to replace a roof for your solar panel installation.

Replace a Roof if It Ages

One of the main factor to consider here is the age of the roof. If the roof is more than 20 years old, it is more likely that it will need to change before the installation. 

Solar panels can be installed on most types of roofs, but if the roof is in poor condition, it may not be able to support the weight of the panels.

The Type of Roof You Have

There are many types of roofs and each has its own considerations for solar panel installation.

The most common type is the asphalt shingle roof, which is typically found in residential homes. Asphalt shingles are easy to work with and provide a good surface.

Metal roofs are more durable than asphalt shingles and can last for many years. But, metal roofs can be more difficult to work same goes for tile roofs are durable and can last for many years.

Both can be very difficult to work with and may need special roofing materials and techniques for solar panel installation. 

The Pitch of Your Roof

The angle of your roof is a key factor to consider when deciding if you need to replace your roof for solar panel installation. If your roof is pitched too steeply, it can be difficult and expensive to install solar panels.

If your roof is too flat, yet, the panels may not get enough sun exposure to generate enough electricity to be worth the investment. The angle of your roof will also affect the angle at which the panels need to be installed, which can impact the cost of the project.

The Size of Your Roof

When considering whether to replace a roof for solar panel installation, the size of the roof is also a significant factor.

A small roof may not be able to support the weight of the solar panel array, and a larger roof may provide more space for solar panels. The size of the roof will also affect the cost of the solar panel installation, as a larger roof will need more panels and materials. 

Importance of Roof for Solar Panel Installation

A roof is a very important part of a solar panel installation. It is the part of the house that handles protecting the rest of the house from the sun, rain, hail, and snow.

If a provider asks you to replace a roof, you need to do it as we provided factors above, and if it’s not properly installed, it can cause serious damage to the solar panels and the rest of the house.
