Measure twice, cut once! 🛠️
The biggest mistake homeowners make when ordering a new rooflight is measuring the wrong part of the roof. It can lead to expensive mistakes and delayed builds, as well as a lot of unnecessary frustration.
To help both homeowners and tradespeople get it right the first time, our team at HITECH Rooflights has put together a simple, straightforward size guide.
Inside, we cover:
✅ Standard sizes vs bespoke designs
✅ The 15% to 20% floor-to-light ratio rule
✅ Structural considerations and joist spacing
✅ Pitched vs. flat roof configurations
We engineer and manufacture our triple-glazed units right here in the UK and offer free standard nationwide delivery.
Don’t cut into your roof without reading this first!
