Worried About Holes In Your Roof?
Last Updated On Roof Tech US
If you're considering solar but worried about holes being drilled into your roof, you're not alone. It's the number one concern we hear from homeowners and it deserves a straight answer.
Roof penetrations don't cause leaks. Poor installation does.
On any sloped residential roof, solar panels must be anchored into the roof structure with specifically engineered fasteners. This isn't a shortcut — it's a structural requirement to handle wind, snow load, and decades of thermal movement. The question isn't whether penetrations happen. It's whether they're executed and sealed in a way that lasts as long as the system itself.
When post-solar leaks do occur, they almost always trace back to one of four things: flashing systems that degrade over time, fasteners that aren't engineered for the application, hardware incompatible with the roof material, or a mounting system with no accommodation for the natural movement of a roof over time.
How AlphaSeal® Was Built for This Problem
Roof Tech's AlphaSeal® system was engineered specifically around these failure points. At its core is RT-Butyl — a proprietary butyl compound that is completely impermeable to moisture and stays flexible across temperature extremes, without cracking, shrinking, or degrading under UV exposure. Paired with specially designed stainless steel fasteners, it creates the first fully integrated, caulk-free mounting system for residential solar.
The result is 100% watertight performance backed by an industry-leading 25-year warranty against leaks due to product failure — effective from the date of installation.
We also offer our Truck Roll Rebate Program: if any water intrusion occurs within the first two years of the warranty period, Roof Tech compensates the installer up to $3,000 per job. A company that isn't confident in its product doesn't make that offer!
