Solar panel FAQs

Can you install solar on any type of roof?

Our contractors have replaced many types of roofs, and there are very few limitations with our team. The main thing is that the mounting hardware will vary depending on material and panels used.

How many solar panels do I need?

The number of solar panels that you need will vary depending on the amount of your electric bill. The average home in a sunny climate typically needs anywhere from 18-20 panels and will usually offset an electric bill of about $200 a month.

Is it a good idea to install solar and replace roofing at the same time?

It’s a fantastic idea! The warranty periods are about the same. We have a 50-year warranty on most of our roof systems and a 25-year warranty on the solar. It’s great to start them at the same time.

What goes into a roof system?

A durable roof is made of more than just shingles. Protecting your home requires a complete roofing system that creates a waterproof barrier, defends against nature’s elements, and provides proper ventilation. In hot areas, homeowners need to think about the extra heat and sun exposure, too.

Your total roof system needs to consist of barriers, underlayment, starter shingles, hip and ridge shingles, ventilation products, and insulation. In order to prevent leaks, you need to start with the right underlayment.

Water barrier products, such as the Owens Corning Weather Lock, protect your new roof from wind, rain, and other elements, while barriers and underlayment stop moisture and mold from seeping through your roof. For added quality, synthetic material like Owens Corning ProArmour with Fusion Back Coating Technology is stronger than traditional felt underlayment, reducing the chance of tears and leaks.

How long does a roofing project take?

It varies, but for most houses, we’ll be in and out within 3-4 days. If you have a big house, it’s going to take longer. 3-4 days is a pretty good average time for a roofing project.

Can I get a new roof if I already have solar panels installed?

The great thing about working with Semper is we’re a solar contractor, and we’re a roofing contractor. A majority of systems we can remove and reinstall for you without getting anyone else involved.

If I lose power from the utility company, will my solar still work?

No. For your solar system to power your home in a grid outage, you would require battery storage for your home. We do offer those here at Semper so, if you are interested, please ask your sales rep.

Can I use my solar if there is a power outage?

Unfortunately, your solar system does also turn off during the power outage unless you have battery storage. These are all grid-tied systems. They do need power recognized to be able to convert the energy from the Sun into usable power to the grid.

What happens if there is an issue with my solar?

If, by any chance, there are issues with your panels, we try to troubleshoot with you through the phone remotely. If that does not work, we try to get one of our technicians out there by the next day, or sometimes the same day. If the problem still persists, please fill out our schedule service form

What does it mean to be an Owens Corning Platinum Contractor?

It means we’re in a very select group of contractors. We’re 1-in-500 in the nation. We offer some of the best warranties in roofing including a 50-year workmanship warranty on all Owens-Corning projects that we complete and a lifetime warranty on their materials.
