The short answer
A range of ages. Older village buildings near St Mary Magdalene and the Tabernacle may carry stone slates or clay tiles, while twentieth-century houses and extensions usually carry concrete tiles or flat roofing. Each covering fails in a different manner, so we identify it before pricing anything.
Rodborough has no single roof type. It is a hillside village, built up over several centuries beside a common, and the rooflines show that history. A roofer who arrives with one answer for every house is guessing.
Q1.1How do you tell what is up there?
From the ground you can read plenty: the colour and grain of the covering, the size of the units, the way the courses run, and whether the ridge is bedded in mortar or clipped down. In the loft you read more, because a stone slate or clay tile looks nothing like a concrete tile from beneath, and the battens, pegs or nails give away the age of the work. We photograph both sides and send the pictures with the written quote.
Q1.2Will an older Rodborough roof be repaired differently?
Considerably. Eighteenth-century buildings on the Cotswold edge were often framed in heavy timber to carry heavy coverings. Putting a different material on such a frame changes the load, and a replacement weighing 15 per cent or more over the old covering means Building Regulations approval, because the rafters carry the difference. A twentieth-century house on concrete tile is far more forgiving, and a like-for-like patch is often all it wants. Between those two extremes sit the Victorian and Edwardian houses on the slopes above Stroud, where slate, clay and early machine-made tiles can all turn up on neighbouring roofs.
Q1.3Where do you look first?
At the high points, because wind works there first. Ridge and hip fixings, verge edges, chimney flashings and the line along which a rear extension joins the original house are the places water tends to find. A roof repair that deals with those properly can remove the need for anything bigger, and the written quote tells you which it is.
For stone or clay roofs on the older buildings, our Cotswold stone roofing page describes how those coverings are laid and why the narrowest repair is usually best.
