The correct pitch for a flat rooflight

The correct pitch for a flat rooflight

Your skylight should enhance the look of your home - not cause problems to your property. That’s why it’s important to pitch your skylight properly when it’s installed. Pitch it incorrectly and you’ll experience pooling water and stained glass, pitch it correctly and you’ll enjoy glorious views and natural light all year round. Here’s how to get it right, first time.

 

Pitching your flat rooflight

To encourage water run-off and minimise staining, your flat rooflight should be installed with a minimum of five degrees pitch. This stops larger pools of water forming and ensures your glass stays clean.

Flat roofs are often built with a slight pitch for drainage purposes to avoid membrane being damaged when pooled water freezes. You can go ahead with a standard installation if the flat roof has been built with a pitch greater or equal to five degrees. If your roof doesn’t have at least a five degree pitch, one can be created with a small timber frame.

But is there a pitched limitation then? Well, it depends on the type of system. 

  • Lean-to : maximum pitch 45 degrees
  • Flat roof : no limitation


Coated glass for a cleaner finish

Keeping your rooflight free from dirt and grime doesn’t stop after installation, but that doesn’t mean you need to root around in your shed to find your ladder and cleaning gear. All our skylights can be made with chemically coated glass that allows water to run off more quickly - carrying away dirt to ensure long term shine.
