Will Solar Panels Leak Your New Roof? Here's the Proof They Won't
Earthlight Technologies • August 7, 2026
"Will solar panels leak my roof?" It's one of the first questions we hear from homeowners, especially those who've just put on a brand-new roof and don't want to risk it for a solar installation. It's a completely reasonable worry — a roof leak is expensive, disruptive, and exactly the kind of thing you don't want tied back to a decision you made to save money on electricity.
So we asked Johnny, one of our expert installers, to show homeowners exactly what happens underneath a solar panel mounting point, and why a properly installed system shouldn't put a brand-new roof at any added risk.
The Real Difference Is in the Hardware
Every solar mounting point starts with a penetration through the roof — there's no way around that. What matters is what happens at that penetration point, and that's where the equipment choice makes all the difference. Earthlight uses IronRidge's roof attachment hardware, which comes with a genuinely adhesive, sticky underside. Once it's placed on the shingle, it seals down so thoroughly that it's almost impossible to remove without damaging the surrounding shingle — which is exactly the kind of bond you want at a roof penetration point.
The detail that sets this hardware apart shows up the moment the mounting screw goes in. As Johnny points out, the screw pulls a significant amount of that adhesive sealant down with it as it drives through the foot and into the roof. That's a meaningful difference from many other mounting feet on the market, which only seal the surface around the screw but leave the shank itself dry as it passes through.
Why Surface-Only Sealing Isn't Enough
Here's the problem with mounting hardware that only seals at the surface: if water ever works its way underneath a shingle — which can happen over time with wind-driven rain or ice damming, even on a well-installed roof — it can travel down the screw shank itself and find its way into the roof deck. The top of the penetration might look perfectly sealed, while a slow leak develops underneath, completely out of sight.
Because IronRidge's hardware pulls sealant down the shank as the screw is driven, that pathway gets filled from the inside out, not just capped at the top. It's the difference between sealing the surface of a problem and sealing the actual path water would need to travel. On the installations we've inspected, the underside of the roof deck around these penetration points stays completely dry — which is the real test of whether a mounting system does its job.
Built With Your New Roof's Warranty in Mind
For homeowners with a recently installed roof, this distinction matters even more. A brand-new roof usually comes with a manufacturer's warranty, and the last thing you want is a solar installation that puts that warranty at risk or creates a leak that shows up years down the line with no clear cause. Choosing mounting hardware that seals penetrations from the inside out is one of the ways we make sure a new roof and a new solar system can coexist without one putting the other at risk.
This is also part of why Earthlight built out its own roofing division — when the same in-house team understands both roofing and solar installation, there's no gray area about whose responsibility a penetration point is, and no guesswork about whether the hardware is compatible with your specific roofing material and warranty terms.
If you're curious about the full mounting process from start to finish — including how the rails and microinverters go on after these anchor points are set — we walk through that step by step in our post on how solar panels attach to the roof.
Frequently Asked Questions
Will solar panels void my roof warranty?
It depends on your roofing manufacturer's specific terms, but properly installed mounting hardware that seals penetrations correctly, like the IronRidge system shown here, is designed to protect the roof rather than compromise it. It's worth confirming your roof's warranty language before installation, which our team can help you review.
How does solar mounting hardware prevent roof leaks?
Quality mounting feet use an adhesive sealant that gets pulled down the length of the mounting screw as it's driven in, sealing the penetration path from the inside out rather than only at the surface. This prevents water that gets under a shingle from traveling down the screw and into the roof deck.
Is it safe to install solar on a brand-new roof?
Yes, in fact it's often the ideal time, since you won't need to remove and reinstall panels for a roof replacement down the line. The key is making sure the installer uses mounting hardware designed to seal penetrations properly so the new roof's integrity and warranty are both protected.
What happens if water gets under a shingle near a solar mount?
With mounting hardware that only seals at the surface, water that gets under a shingle can travel down the mounting screw into the roof deck, potentially causing a hidden leak. Hardware that seals the screw shank itself, from the inside out, closes off that pathway.
Who is responsible if my roof leaks after solar installation?
This is exactly why we recommend working with a company that handles both solar and roofing in-house. When one team understands both systems, there's no ambiguity about responsibility for a penetration point, and any issues can be addressed directly rather than becoming a dispute between separate contractors.
