Smoke Vents Waterproofing That Keeps Life-Safety Vents Dry
Smoke vents waterproofing protects one of the largest openings in an industrial roof. A smoke vent is a hinged or louvred unit set on a raised kerb. Its job is to release smoke and heat in a fire. For the other 364 days it is simply a big hole in the roof with a frame around it, and the junction between that frame and the roof sheets is a regular source of leaks.
Leak Lock Insulation Contracting seals the kerbs, flashings and fixings around smoke vents without interfering with the way the vent opens. Facility managers and warehouse owners use this service when water appears below vent positions, or when a roof inspection finds cracked sealant around the upstands.
Signs Your Smoke Vents Are Leaking
For example, clients contact us for one or more of the following reasons.
- Water below the vent: drips or stains directly under the unit.
- Cracked kerb sealant: mastic at the base of the upstand has split.
- Lifted flashings: metal trims around the vent have come loose.
- Rust at the corners: kerb corners corrode first where water sits.
- Worn gaskets: the lid no longer closes tight on its frame.
- Ponding behind the kerb: water is trapped on the upslope side.
Our Smoke Vent Sealing Services
Kerb Waterproofing
EPDM membrane taken from the roof sheet up the side of the kerb.
Corner Detailing
In addition, kerb corners reinforced, since they are the usual failure point.
Flashing Repair
Loose or corroded flashings refixed or replaced by our fabrication team.
Back-Gutter Sealing
Similarly, the upslope side of the vent detailed so water is diverted around it.
Fixing Sealing
Screws through the kerb and flashing sealed.
Frame Joint Sealing
Also, joints in the vent frame sealed without restricting movement.
Our Smoke Vent Waterproofing Process
Because every site is different, we adapt these steps to your smoke vent waterproofing project.
- InspectionBefore anything else, we check the kerb, flashings, corners and the closing edge of each vent.
- PreparationThen, we remove old sealant and rust and clean the surfaces.
- Flashing RepairsAfter that, we refix or replace damaged metalwork.
- Membrane ApplicationAs soon as that is done, we bond EPDM around the kerb and onto the roof sheets.
- Check & TestFinally, the vent is checked for free operation and the seal is water tested.
Materials & Methods
Kerbs and flashings are sealed with EPDM membrane and bonding adhesive. The membrane is kept clear of hinges, actuators and the opening edge, so the vent operates as designed. Any mechanical or fire-system fault we notice is reported to you for your fire maintenance contractor.
In short, the work includes the following.
- EPDM membrane around kerbs and upstands
- Reinforced corner pieces
- Fabricated replacement flashings where needed
- No sealant on moving or opening parts

Smoke Vent Waterproofing FAQs
Questions about leaking smoke vents. Also, you can call us with any other question.
No. We seal the kerb and flashings around the unit. Hinges, actuators and the opening edge are left free, and we check that the vent still operates after the work.
Corners are where flashings are cut and joined, and where water slows down. Sealant there is under the most stress and tends to fail first.
No. Mechanical and fire-system servicing should be done by your fire maintenance contractor. Our scope is the waterproofing and metal flashings.
Yes. Glazed or polycarbonate smoke vents have a similar kerb detail, which is sealed in the same manner.
A few vents can usually be completed in a day. However, we programme larger numbers after the inspection.
