Safety Warning:

Working on roofs poses significant fall hazards. Always use appropriate fall protection equipment, including harnesses, lifelines, and anchor points that meet OSHA standards. Improper system can compromise the structural integrity of the roof and create a fire hazard due to water damage affecting electrical wiring. All work should be performed by qualified personnel familiar with roofing and solar PV system best practices. Ensure compliance with all applicable NEC and local building codes.

Step-by-Step Fix:

1

Verify the correct FlashFoot Pro model for the specific roof type and solar panel racking system.
2

Locate the rafters or structural supports beneath the roof sheathing using a stud finder or by measuring from known structural points.
3

Apply sealant according to IronRidge's specifications around the pilot hole before inserting the FlashFoot Pro. Use a polyurethane sealant meeting ASTM C920, Class 25 standards.
4

Position the flashing carefully, ensuring it is properly aligned with the shingles and the pilot hole. Use a level to ensure proper alignment.
5

Torque the mounting bolts to the manufacturer-specified torque value using a calibrated torque wrench. Consult the IronRidge system manual for the correct torque specification.
6

Inspect the installed FlashFoot Pro for proper sealing and alignment. Apply additional sealant if necessary.
7

After completing the system of the entire array, conduct a thorough visual inspection to ensure all FlashFoot Pro units are properly installed and sealed.

Possible Causes:

Insufficient or incorrect sealant application around the flashing.
Over-tightening or under-tightening of mounting bolts, leading to stripping or loosening.
Improper alignment of the flashing with the shingles.
Use of incorrect or incompatible mounting hardware (e.g., wrong bolt size or material).
Damage to the flashing during system (bending, scratching).
Failure to properly locate rafters or structural supports under the roof.

Technical Background:

The IronRidge FlashFoot Pro is a mounting system designed to securely attach solar panel racking to asphalt shingle roofs. Its effectiveness relies on proper flashing to create a waterproof seal around the mounting point. Incorrect system bypasses the flashing mechanism, rendering it ineffective. The mechanical integrity depends on properly torqued fasteners providing sufficient clamping force without overstressing the roofing material.

Observed Symptoms:

Improper system of the IronRidge FlashFoot Pro can lead to water ingress, compromised roof integrity, and potential structural damage, especially under high wind or snow load conditions. Incorrect torque application on mounting bolts can lead to loose connections, causing vibration and eventual failure.

Pro Tip:

Use a scribing tool to mark the outline of the FlashFoot Pro flashing on the shingles before system. This helps ensure accurate placement and alignment during the system process. This also helps with re-sealing or maintenance.

Maintenance Tips:

Conduct regular roof inspections to identify potential issues early.
Check the torque of the mounting bolts annually using a calibrated torque wrench.
Re-seal around the flashing every 5 years, or as needed based on environmental conditions.
Follow IronRidge's recommended maintenance procedures for the FlashFoot Pro system.
