Velux roof window installation
in Waterloo
On the building stock of Waterloo — interwar villas, natural slate roofs, dormers and multiple hips — Velux roof window installation calls for a method that fits. Opening up, fitting and weather-sealing roof windows, with a neat interior finish.

The context in Waterloo
Why here in particular
What is different in Waterloo is the context: interwar villas, natural slate roofs, dormers and multiple hips. The tall mature trees, handsome as they are, are also the first cause of blocked gutters and persistent moss.
A roof window that leaks is almost never the window: it is the flashing. A sealing kit that does not match the type of roof covering, and water gets through the first winter that comes.

Frequently asked questions
Velux roof window installation in Waterloo
The questions we get asked most often before this kind of job.
Do you fit blinds and shutters?
Yes, at the same time. That is the right moment: the joint is open and the feed is run cleanly.
Do you need a permit?
Often not for a window in the plane of the roof, sometimes yes depending on the municipality and the area. We check beforehand, which saves a nasty surprise.
Which size to choose?
The width depends on the spacing between the rafters. We measure before ordering: that is what stops anyone butchering the roof timbers.
Do you come out to Waterloo with no extra call-out charge?
Yes. Waterloo is one of our 17 municipalities: the call-out is included in the quote, not added at the bottom of the invoice.
