Waterproof Solar Mounting Aluminum Flashing Kits

The Waterproof Solar Mounting Aluminum Flashing Kits are engineered specifically for asphalt shingle and pitched roofs, combining a leak-proof flashing plate with an adjustable L-foot bracket. Designed for residential and commercial PV installations, the Flashing Kits provide a secure, corrosion-resistant attachment point that safeguards roof integrity while supporting solar panels in both portrait and landscape orientations.

Product Advantages

Leak-Proof Sealing

Each Flashing Kit features a raised tapered hole on the flashing plate, paired with a curved rubber gasket. This combination creates a watertight seal around the roof penetration, preventing moisture ingress and long-term water damage.

Adjustable L-Foot Design

The L-foot bracket within the Flashing Kits allows for easy height adjustment, enabling precise alignment with rafters and accommodating variations in roof pitch and panel tilt requirements.

Versatile Rail Compatibility

Pre-drilled holes and included lag bolts make the Flashing Kits compatible with all common aluminum alloy rails. The system supports both framed and unframed panels in portrait or landscape layouts.

Installation Overview

Rafter Alignment
Flashings must anchor directly into roof rafters, not merely into the decking, to ensure structural integrity.
Shingle Integration
Slide flashing under existing shingles with the leading edge positioned to prevent water infiltration. A minimum 1" overlap over the exposed lower shingle is recommended.
Sealant Application
Apply a bead of ASTM D4586-compliant sealant beneath the flashing, leaving a small drainage gap at the lower center to allow moisture escape.
Torque Specification
Lag bolts should be tightened to 8–10 Nm (70–88 lb-in) to ensure EPDM washers compress fully and create a watertight seal.

FAQ

01.How does the system prevent water leakage?

The raised tapered hole on the flashing plate, combined with a curved rubber gasket, creates a compression seal that directs water away from the penetration point.

02.Is the kit suitable for both residential and commercial projects?

Absolutely. The Flashing Kits are versatile enough for single-family homes, multi-unit residential buildings, and large commercial rooftops.
