Whirly Birds & Skylights

It depends on roof size, roof space volume, and how hot the roof cavity gets. Some homes benefit from a single unit, while others need multiple vents spaced correctly for balanced airflow. During inspection, we assess the roof layout and recommend the most effective placement and quantity.

They help reduce trapped heat in the roof space, which can lower heat transfer into the rooms below—especially in summer. Results vary depending on insulation, roof design, and airflow paths. For the best outcome, ventilation works best when combined with good insulation and correct roof space airflow planning.

Skylight placement depends on roof framing, sun direction, and what room you want to brighten. We choose positions that maximize natural light while keeping waterproof detailing correct. We also consider glare, heat gain, and privacy to ensure the skylight improves comfort—not creates new issues.

Most skylight leaks come from poor flashing. We install with correct flashing, sealing, and water direction planning so rain is guided away from the skylight edges. We also check roof pitch suitability, sheet overlap direction, and surrounding areas to ensure the installation remains reliable long-term.

We work within the roof’s framing layout and follow safe methods when creating an opening. If framing adjustments are required, we handle them correctly so the roof remains structurally sound. We’ll explain the approach before starting, especially for larger skylights or complex roof designs.
