What to Know Before Installing Solar Panels on Your Roof
Installing solar panels is a smart way to save on energy costs and reduce your environmental footprint. But before you commit, it’s important to make sure your roof is ready. Many homeowners don’t realize that the condition of their roof plays a big role in the success and longevity of a solar installation. If your roof isn’t in great shape, you may be setting yourself up for unexpected repairs, extra costs, or even damage down the road.
As roofing professionals, we know how important it is to evaluate your roof before you go solar. In this guide, we’ll walk you through what you need to consider to protect your home and get the most out of your solar investment.
Check the Age and Condition of Your Roof
Before installing solar panels, the first thing to think about is how old your roof is. Most asphalt shingle roofs last between 20 and 30 years. If your roof is already nearing the end of its lifespan, it’s a good idea to replace it before adding solar panels. Installing panels on an old roof could mean you’ll need to remove them later for repairs or replacement, which adds time and cost.
Even if your roof is newer, you’ll want a professional inspection to check for signs of wear. Cracked shingles, soft spots, or sagging areas could lead to problems once solar panels are mounted. Fixing these issues in advance can prevent complications and help your roof support the weight of the solar system safely.
Understand the Risk of Leaks
One of the most common concerns with solar installations is the risk of roof leaks. Solar panels are attached using mounting brackets, which often require drilling into the roofing material. If these connections aren’t properly sealed or if they’re added to a weak or damaged area, they can create pathways for water to enter your home.
Working with a roofer before the solar installation ensures your roof is in strong condition and that penetrations are made in safe, stable areas. After the panels are installed, you should also schedule a follow-up inspection to make sure everything is still sealed and water-tight.
Why a Roofing Inspection Matters
Many solar companies focus solely on the energy system. They don’t always evaluate the condition of your roofing materials or the underlying structure. That’s where your local roofing expert comes in. A thorough inspection can identify potential weak spots and help you avoid long-term issues.
At Roberts Roofs Inc., we regularly partner with homeowners planning to go solar. We’ll check your roof deck, flashing, and shingles to make sure they’re all solid. If we find anything that could cause problems later, we’ll provide a repair or replacement plan before the panels go up.
What to Do Before Installing Solar Panels
To make sure your roof is ready for solar, here’s a quick checklist of things to review before installation:
• Schedule a professional roof inspection
• Ask about the age and remaining lifespan of your roofing material
• Repair any damage or weak spots
• Replace the roof if it’s near the end of its life
• Review mounting plans with your roofer and solar installer
• Confirm warranty coverage for both roofing and solar components
This process helps protect your investment and ensures that both your roof and solar system last as long as possible.
Protect Your Roof and Your Investment
Solar panels are a great upgrade, but your roof needs to be up to the task. By working with a roofing professional first, you avoid damage, extend the life of your roof, and make sure the solar installation goes smoothly. It’s always easier and more cost-effective to deal with roofing issues before the panels are installed than to try to fix them afterward.
