The Need For Proper Planning
Solar panels are designed to last 25 to 30 years. Residential roofing systems can last just as long, though it will depend on the material and its expected life span. Generally, a roof can exceed the solar panels service life if it is well-maintained and can withstand constant exposure to the elements.
Installing the solar panels and removing them again to do roofing work is not just labor-intensive but also costly. Roof repair and replacement experts recommend that you check the roofs expected life span first before you go solar. Replacing your current roof makes sense if it is nearing the end of its service life.
How Do Solar Panels Affect Roof Replacement
As you probably already suspect, you will have to have your solar panels removed in order to replace your roof, theres just no way around it. Unfortunately, this means that you wont have access to renewable energy while your roof is being replaced.

This will inevitably increase your utility bill, so keep that in mind if youre considering a roof replacement.

Instead, youll have to rely on your solar panel installers to take your system down before your roof replacement.

This means that you should include these couple of days when planning your replacement project.

How Much Does Solar Panel Removal Cost If You Need To Replace Your Roof
If you run into a roofing issue, and need to replace the roof post-installation, there will be labor costs associated with taking the panels off your roof and putting them back on.
Unfortunately, its hard to give specifics on the costs associated with this labor, as it can vary greatly. Installers will have different rates for their labor, and the cost can also vary based on the size of the system, how many panels will need to be removed, and whether you need a place to store the equipment.
If mounting hardware also needs to be removed in order to replace your roof, this will add onto the cost. On average, residential installations tend to cost somewhere between $1,500 to $6,000 to remove and reinstall.
For this type of work, its common to return to your original solar installer for the labor theyll be most familiar with the ins and outs of your particular system installation.

What Is The Best Roof For Solar Panels
One of the great things about solar panels is the fact that they can be installed on any type of roof, however, different roof types can affect the solar panel installation process and the solar panel efficiency.
Position and angle
The main factor to take into consideration when choosing the best roof section for solar panels is position. Theres an optimum angle for solar panels that allows them to capture and convert as much sunlight as possible. A 30-degree angle is perfect.
And the panel should not just be pointed in any direction. By facing north, your panels will benefit from long hours of sunlight, allowing them to produce more electricity.
If your home has a multi-section slanted roof, it might be that a section of your roof is positioned perfectly facing north. But if not, that does not mean your roof is not suited to solar panels. East or west facing panels can also be effective, as theyll receive a lot of sunlight at different times of day.
As for flat roofs, brackets can be used to position panels at the best angle, facing north, west, or east.
While solar panels can be installed on all different types of roofs, they all come with different benefits.

Wooden shake roofs, on the other hand, tend to last for about 30 years, offering a slightly lesser lifespan than the clay tile roofs.
