Roof Penetration
A hole drilled through the roof to attach solar panel mounting hardware. Properly flashed penetrations use waterproof sealant and metal flashing to prevent leaks for the life of the system.
Why It Matters
Many homeowners worry about roof leaks from solar. Quality installers use industry-standard flashing that keeps the warranty intact and prevents water intrusion.
