The roof of the house is the only thing that can keep weather like rain and snow from getting through to your loved ones inside. This makes it among the most significant purchases you will ever make. Thus, maintaining its condition is crucial.
But solar panel installation necessitates extensive drilling into the roof and the placement of typically heavy equipment. In this regard, will the solar panel installation void your roof’s warranty?
Here, we’ll go over the basics of roof warranties, including what they cover, the different kinds of roofs, and how bad solar system installations might nullify your warranty coverage.
Do Solar Panel Systems Void the Warranty?
Usually, no. As long as the solar panel system mounted by the solar installer is per the specifications provided by your roofing contractor, solar panel installation should not invalidate your roof’s warranty. This should ensure that the terms of the warranty are met.
Waterproofing your roof and flashing are integral parts of any proper installation since they seal the roof and prevent water from entering the structure. However, solar panel installation shouldn’t be done on a roof that will only last for less than ten years. In fact, right after getting a new roof is often believed to be the ideal opportunity to install solar panels.
Understanding Roof Warranties and What They Entail
There are typically two components to a roof warranty for the property. The first is the warranty that the installer gives you, which pays for the actual labor involved in getting the roof installed.
The length of this type of warranty is up to the roofing firm that installed your roof, but it often ranges from 8 to 10 years. Therefore, the firm responsible for the installation must pay for any damage to your roof that results from the installation being done incorrectly.
The manufacturer’s warranty on the roofing materials is another component; it may last anywhere from 25 to 50 years, based on the product installed. Consequently, the utility company will replace your faulty roofing material under the manufacturer’s warranties if it can be confirmed that the damages were not the result of poor installation.
Before beginning any roofing work, it is best to clear everything up with the material producer and the roofing contractor. This can help you understand how a solar system installation may influence your warranty.
As solar panels and roof installations are often done simultaneously, it’s a good idea to inquire whether the roofing instructor you’re considering can recommend solar companies. Sometimes, they may even provide solar system installation services themselves.
Types of Roofs and Racking Systems
It’s important to remember that solar panels can last for at least 25 years before they need to be replaced. Following these criteria, several common roofing styles are described below.
Concrete or asphalt shingles are typically used while constructing a roof. Installation of panels requires screws that may pierce the roof, flashing to give support, and sealant to prevent water infiltration. Solar panels can be installed more easily on these roofs than on tile roofs.
Numerous roofs are constructed with tiles made of clay, slate, or terra cotta, all of which can’t be drilled. Therefore, it is more difficult and has a higher installation cost since the supports must be connected beneath the tiles, and the rooftop deck must always be drilled.
Flat roofs often utilize membrane roofing. In order to mount the panel on flat rooftops, a slanted ballasted system is utilized. They have the benefit of being less expensive and requiring no ceiling drilling. Mechanically mounted racking systems are yet another popular option.
Roofs with Standing Seam Metal
Roofs constructed of metal are among the most solar-friendly options because of their durability and low reflectivity. Assembling the panels is quick, easy, and risk-free due to the vertical seams. No holes need to be bored in the ceiling, and no waterproofing is required.
Why Would a Poor Solar Installation Void the Warranty of your Roof?
In most circumstances, a solar installation will not void your roof warranty, assuming the installer followed all manufacturers’ instructions. A solar installation can decide voiding your roofing warranty due to one of the following ways:
- Negligence during roof repairs, leading to broken tiles or a weakened roof membrane
- Using the wrong fasteners to join the floor to the roof
- Cheap racking system that isn’t well made and lacks essential waterproofing elements
While many individuals are interested in installing solar panels, some may be hesitant due to concerns about the holes these would require in their roofs. If the installation is executed properly, however, it will not nullify the lifetime warranty on your rooftop.
Moreover, if you want your roof’s warranty to hold up, check in with the company that made and mounted it. If at all feasible, it’s wise to have the same firm install both your roof and your solar panels.
