Installing Solar Panels on an Asphalt Shingle Roof in Illinois: What You Need to Know

SunBeam Innovations does not cut corners on mounting hardware. We utilize premium flashing systems designed specifically for asphalt shingles to withstand the Illinois freeze-thaw cycle. Instead of just driving lag bolts through the shingles and covering them in caulk, we lift the existing shingles and slide a heavy-duty metal flashing underneath. This creates a physical barrier that directs water and melting snow completely away from the roof penetration.

Once the specialized flashing is in place, we drive the lag bolt directly into the structural rafter of your roof. The penetration point is then injected with a high-grade, weather-resistant sealant. The result is a watertight seal that is often stronger than the original roof itself, guaranteed to withstand heavy ice accumulation and driving rain.

We work within the strict guidelines required by major asphalt shingle manufacturers. Because our installation process utilizes industry-leading waterproofing techniques, adding solar through SunBeam Innovations will keep your existing roof warranty fully intact.
