Wanhos Shingle Roof Flashing Kit Installation: Secure & Waterproof Solar Mounting Guide
Ensure a leak-proof and robust foundation for your solar panels with the Wanhos Shingle Roof Flashing Kit. This step-by-step guide details the installation process, emphasizing waterproofing integrity and structural stability for your solar mounting system.
Prepare Installation Tools
Gather these essential tools before starting your Wanhos flashing kit installation:
Tape Measure & Marker Pen (Precise marking)
Power Drill & Drill Bits (Pilot holes)
Screwdriver & Hex Key/Allen Wrench (Fastener tightening)
Socket Wrench or Adjustable Wrench (Bolts/nuts)
Utility Knife (Shingle trimming if needed)
Safety Gear: Gloves, Safety Glasses, Fall Arrest System
Wanhos Flashing L-Feet Kit Accessories & Materials
High-quality materials ensure corrosion resistance and durability:
Aluminum L-Feet (AL6005-T5): High-strength, lightweight, excellent weather resistance. Core load-bearing component.
Aluminum Flashing (AL1060): Flexible, easily conforms to shingle contours, forms critical waterproof layer.
Stainless Steel Fasteners (SUS304): Lag screws, T-Bolts. Superior rust-proofing for long-term hold.
Waterproof Rubber Washers (ADC12 base + EPDM/NBR rubber): Seals penetration points, prevents leaks.
Steel Components (Q235B): Provides robust strength for specific connections.

Asphalt Shingles
Solar Mounting Rails
PV Modules (Solar Panels)
Rail End Clamps & Mid Clamps
Step-by-Step Wanhos Flashing Kit Installation
Locate the Rafters – Find the Solid Base
Measure from inside the attic or use a stud finder to identify rafter positions (typically 400mm-600mm on center, check local code).
Clearly mark the centerline of each rafter on the shingle surface. Crucial for structural integrity.
Position the Flashing & L-Feet – Prep for Waterproofing
Carefully lift the asphalt shingles at the marked location.
Slide the Wanhos aluminum flashing underneath the lifted shingles, ensuring it lies flat over the rafter centerline.
Align the flashing perfectly over the rafter. Mark the screw hole positions through the flashing.
Remove the flashing. Assemble the stack directly on the roof deck:
Roof Surface
Waterproof Rubber Washer
Wanhos Aluminum L-Foot (Vertical leg oriented for rail attachment)
Waterproof Rubber Washer
Attach the L-Feet – Secure the Mounting Point
Pre-drill pilot holes at the marked positions (drill bit slightly smaller than screw diameter).
Using SUS304 Stainless Steel Lag Screws (or provided T-Bolt anchors) and a drill/driver, securely fasten the L-foot assembly directly into the roof rafter.
Tighten to the recommended torque (typically 8-10 Nm / 70-88 lb-in) to ensure the waterproof washers compress fully, creating a seal.
Install the Solar Mounting Rail – Connect the Structure
Position the solar mounting rail onto the fixed L-feet, aligning the mounting holes.
Insert SUS304 Stainless Steel Bolts, washers, and nuts through the rail and L-foot holes.
Tighten firmly using a socket wrench or adjustable wrench. Ensure the rail is secure and level (use a spirit level). Adjust L-foot height if necessary.
Install the Solar Panel – Mount the PV Module
Place the first PV module onto the rails, maintaining a minimum 25mm (1 inch) gap from the rail ends (for expansion/contraction and clamp placement).
Slide rail end clamps into both rails, positioning them against the PV module’s edge.
Tighten the end clamp screws securely using a hex key (Allen wrench) or hex driver.
Continue installing modules using mid-clamps between panels.
Pro Tips for Wanhos Kit Success
Waterproofing is Paramount: Ensure rubber washers are correctly positioned and uniformly compressed. Flashing must remain fully tucked under the shingles. Apply a bead of high-quality, non-bituminous roof sealant (e.g., polyurethane) around screw penetrations for extra protection.
Structural Integrity is Key: L-feet must anchor into solid roof rafters. Fasteners must be tightened to specification. Never mount solely into roof decking.
Follow Codes & Safety: Always adhere to local building, electrical, and solar installation codes. Do not work on the roof in wet, icy, or windy conditions.
