Under the Downs
A town beneath the chalk, and what that means for a roof
The escarpment shapes how light arrives and weather is met, and the protected landscape makes the address the first question.
Reigate is a long-settled market town with a hard edge of chalk behind it. The escarpment shapes how light arrives, how weather is met and how far sound carries across the vale.
The town lies about 19 miles south of central London, and the North Downs rise immediately to its north. Anyone who has walked up from the High Street knows how quickly the ground climbs. For a rooflight, the slope of the land matters in a practical way. A loft room on a rear slope that faces the Downs receives its daylight at an angle that differs from a room facing the open vale, and the glass should be sized and placed for the light that room actually gets. Our page on where to position a skylight in a room covers the reasoning, and the sizing guide covers the arithmetic.
The wider landscape is protected. The Surrey Hills National Landscape covers the North Downs and the Greensand Ridge, and its chalk downs run across Dorking, Reigate and Oxted. That does not turn every Reigate roof into a planning problem. It does mean the first conversation about any opening is about the address, what is around it, and which rules apply there. We find that out before we price anything, not after.

Reigate is also well inside our radius. We cover Crawley and 30 miles around, so a survey here is a short drive, and the same people who measure the roof fit the glass.
