Lower Wanborough shows how a village roof line grows over centuries. The appraisal says thatch predominates, with Welsh slate and stone tiles between, and later alterations in concrete tile. That mix needs a roofer who reads each roof for what it is.
Q1.1What happens where different coverings meet?
The line where one roof meets another is where leaks start. A slate roof that abuts thatch needs a lead flashing dressed so water is carried clear and does not run into the thatch. Lead is a metal sheet that is bent and dressed to fit, and its weight, called its code, is chosen to suit the position. A gutter above a thatched eave is best avoided or carefully detailed, since it can overflow onto the thatch.
Q1.2What about chimneys and abutments?
Chimney stacks in a village like this are often tall and exposed, with cement pointing that has cracked and let in rain. The stack, the flashing and the flaunching, which is the mortar slope on the stack top that sheds water off the pots, all matter. We check each from a ladder or a platform, then photograph the stack so you can see its condition.
Q1.3How is a thatched neighbour kept safe?
Where a roof shares a party wall with a thatched cottage, we plan the sequence so no loose debris or hot work is anywhere near the thatch. Our chimney repairs and slate roofing pages describe the methods.
If you have a thatched roof of your own, a thatcher is the right person to look at it. We work around thatch, not on it.
Scaffolding needs thought in a lane like this. Chapel Lane is a short, narrow lane, other old streets leave little room as well, and a scaffold tower has to leave room for neighbours and not rest on a thatched eave or a delicate stone coping. We plan access at the survey stage and tell you what we need, whether that is a parking bay, a few days' notice to a neighbour or a licence from the highway authority.
Finally, gutters. Cast iron and half-round profiles suit older buildings, and a modern plastic run clipped to a thatched eave can do harm when it overflows. Our gutters, soffits and fascias page covers options by building type.
