Smart Passive Ventilation Solution for Metal Roofs and PEB Structures.
Smart Passive Ventilation Solution for Metal Roofs and PEB Structures.
Carmika™ Ridge Vent, a premium ventilation system under the Carmika™ brand by Shish SmartBuild™, is engineered exclusively for metal roofs and Pre-Engineered Buildings (PEBs) to deliver continuous passive ventilation and thermal comfort.
In traditional metal structures without proper ridge ventilation, internal temperatures can rise 8°C to 15°C higher than outdoor ambient temperatures, causing excessive heat buildup, discomfort, increased cooling costs, and accelerated roof aging.
Carmika™ Ridge Vent prevents heat buildup by allowing warm, moist air to escape naturally through the roof ridge — helping maintain lower indoor temperatures, reduce cooling system loads, and extend roof system life by preventing condensation.
Constructed with a rigid polyolefin core and now ~35 mm (±3%) thick, Carmika™ Ridge Vent delivers higher airflow capacity (~16.5 in² Net Free Area per linear foot) compared to thinner alternatives — ensuring superior ventilation across industrial, agricultural, and commercial roofing projects.
At Shish SmartBuild™,
we engineer smarter, healthier, and longer-lasting roofing systems.

Standard Technical Specifications
Installation Guide
Recommended Tools:
Tape measure
Utility knife or heavy scissors
Drill machine / screwdriver
Self-tapping roofing screws
Butyl tape / sealant (optional)
Installation Instructions:
1. Prepare the Ridge
- Clear ridge line area of any debris, framing errors.
- Ensure purlins are properly aligned and spaced.
2. Install Carmika™ Ridge Vent
- Place Carmika™ Ridge Vent centered along the ridge.
- Overlap edges slightly if multiple pieces are joined.
- Cut easily using heavy scissors or a utility knife if needed.
3. Fasten Ridge Vent
- Use self-tapping roofing screws spaced approximately 300–450 mm apart.
- Lightly fasten without compressing the vent too much (maintain airflow gap).
4. Install Ridge Cap Over Vent
- Place the ridge cap over the vent carefully.
- Fasten ridge cap using standard fasteners.
- Ensure the cap extends properly beyond vent edges to protect against rain and weather ingress.
