Industrial roofs often have multiple penetrations—from HVAC units and vents to skylights and exhaust fans. While penetrations are naturally vulnerable points for leaks, at L&L Roofing & Construction, we use proven techniques to ensure your Gainesville facility’s metal roof remains watertight and durable.
How We Handle Roof Penetrations
- Custom Flashing: Metal and membrane flashings are fabricated to fit each penetration.
- Sealant Systems: Butyl tape, gaskets, and high-performance sealants create watertight barriers.
- Curb Installations: Raised curbs for large units like HVAC systems provide extra protection against standing water.
- Reinforced Panels: Around penetrations, we add extra fastening and sealing layers for durability.
- Ongoing Maintenance: Annual inspections help catch early wear around penetrations before leaks develop.
Why Proper Penetration Sealing Matters
- Prevents leaks at the most vulnerable points of your roof.
- Protects expensive equipment, inventory, and interior spaces.
- Maintains warranty coverage (manufacturers require penetrations to be sealed to spec).
- Extends roof life by reducing water intrusion risks.
FAQ: What If My Industrial Metal Roof Has Lots of Penetrations?
Q: Are penetrations always a weak spot?
A: They can be, but with proper flashing and sealing, they perform just as well as the rest of the roof.
Q: Can skylights be added later without risk?
A: Yes, as long as they’re properly flashed and sealed. We can retrofit skylights and vents into existing roofs.
Q: What sealants do you use?
A: Industrial-grade butyl, silicone, or polyurethane sealants paired with EPDM or neoprene gaskets.
Q: Will penetrations void my warranty?
A: No—when installed to manufacturer guidelines, your warranty remains valid.
