What to consider before you install your rooflights
Installing rooflights or skylights can transform your home, flooding it with natural light and creating a sense of openness and space. A high-quality rooflight not only enhances the aesthetic appeal of your property but also improves energy efficiency, ventilation, and the overall ambiance of your living space. Whether you are adding a rooflight to a kitchen, living area, or extension, following a precise installation process is essential to unlock its full potential. These five expert tips will guide you through a seamless and compliant rooflight installation process. We also have fitting guides available for extra instructions
- Ensure the correct gradient for water runoff
A well-installed rooflight must account for water runoff to prevent pooling on the glazing. The recommended gradient is 40mm for every 1000mm, aligning with the fall of your roof. Before finalising your installation, conduct a simple water test by pouring water at the highest point of the rooflight and observing its flow. This ensures water runs off efficiently, protecting your rooflight and the surrounding structure.
- Proper lifting support for larger rooflights
For rooflights measuring over 1000mm x 2000mm, it is essential to have six people lifting the unit into place—one on each corner and two supporting the sides. This reduces stress on the central section of the unit, preventing potential seal bending that could cause gas to escape over time. Proper support during installation not only ensures safety but also maintains your rooflight’s structural integrity.
- Use the correct silicone for sealing
Selecting the right silicone is critical for a secure and long-lasting rooflight installation. We recommend using a low-modulus, high-movement silicone such as DOW791 for our fixed rooflights and skylights. Using an unsuitable silicone could compromise the unit, leading to failure and invalidating your warranty. Always choose high-quality sealants to protect your investment.
- Double-check your measurements
Before positioning your rooflight, measure the designated area carefully to ensure it matches the internal dimensions of your product. Accuracy is key to avoiding fitting issues or adjustments during installation. Taking the time to check your dimensions will help you achieve a clean and professional finish.
- Secure rooflights when using a crane
If your rooflight is being craned into position, ensure the operator properly straps the middle area of the unit. While corner and edge supports are standard, the middle section can sometimes be overlooked, leading to potential stress on the unit during the lift. Addressing this detail will protect your rooflight from damage and ensure a smooth installation.
