Edwalton has been built in stages. The first large estates went up in the early 1950s, with later estates added in the decades that followed, and in recent years developers have laid out new housing near the A52 on land known as Sharphill Farm. Between those layers sit individual bespoke houses, which are common here, and each has its own roof.
A house from the 1950s often has a plain pitched roof with concrete or clay tiles and a simple loft. The pitch is steady, the rafters are regular and a roof window drops in readily. The loft, if it hasn't been converted, may be shallow, in which case we check headroom before promising a window big enough for a bedroom.
Newer houses often have engineered trusses in the roof. Cutting through a truss is a structural matter, and the opening has to be framed to carry the load. We check the construction in the loft and, where trusses are present, design the opening around them or specify the support needed. That detail is in the written quote.
Bespoke houses have the widest range. Hips, dormers, valleys and mixed coverings all turn up, and each decides where a rooflight can go. The right answer is often the quietest slope, the one that doesn't dominate the front elevation, which is why a slim conservation-style frame is worth considering on a house where the roofline is a feature.
