Why Getting This Right Matters
A poorly ventilated roof doesn’t just get hot — it deteriorates faster, drives up cooling costs, and can cause moisture damage that costs thousands to fix. Bramac ventilation tiles are a proven solution, but only when installed correctly. Here’s how to do it right.
Step 1: Calculate How Many Ventilation Tiles You Need
The general rule is at least 1 ventilation tile per 50 square meters of roof surface, placed in the upper third of the roof slope. For a standard 150 m² roof, that means a minimum of 3 ventilation tiles — though more is better in hot climates. Measure your roof area carefully before ordering materials.
Step 2: Plan the Placement
Ventilation tiles work best when paired with proper eave ventilation at the bottom. Air enters from the eaves, travels under the tile layer, and exits through the Bramac ventilation tiles near the ridge. Mark your planned positions on the roof plan before installation begins — don’t improvise on the job.
Step 3: Installation Process
Remove the standard tiles at your marked positions. Place the Bramac ventilation tile in the same interlocking position as a regular tile — it’s designed to match the profile of standard Bramac tiles so there’s no need for extra sealing or adapters. Secure it according to the manufacturer’s guidance, especially on steeper pitches above 45°.
Step 4: Check the Underlay and Batten Gaps
The ventilation tile is only effective if air can actually flow. Make sure your roofing underlay has a clear gap along the ridge, and that counter-battens create sufficient space between the underlay and the tile layer. A sealed or compressed underlay kills airflow completely.
Common Mistakes to Avoid
- Installing too few tiles: One tile on a large roof won’t do the job. Calculate properly.
- Placing them too low: Ventilation tiles near the eave do almost nothing — position them in the upper zone.
- Blocking the airflow path: Insulation pushed too close to the eave blocks the intake. Leave a clear channel.
- Mixing incompatible profiles: Always match the ventilation tile profile to your existing Bramac tile series.
Pro Tips
In regions with heavy snowfall, consider a snow guard above each ventilation tile to prevent ice buildup over the opening. Also, during summer renovation work, install ventilation tiles before the hottest months — your attic temperature will drop noticeably within days.
When to Call a Professional
If your roof has a complex shape with multiple valleys and hips, airflow planning becomes complicated. The same applies if you’re retrofitting ventilation into an older roof with existing insulation. In these cases, a certified roofer or a Bramac technical consultant should assess the setup before you start.
