BOATHOUSE ON THE RIVER THAMES
Boathouse on the River Thames
The attraction for us as roofers was that this 100-year-old building had its original pantiles remaining which the client and district surveyor insisted we use.
These hand-made terracotta tiles look fabulous but are notoriously difficult to fit as they differ in both size and profile. The lap is a mere 30mm with a gap often up to 20mm between the top and bottom faces.
The way you make the roof watertight is by using a lime and sand joint along the right-hand edge of the tiles. We used red dye in the mix to help lessen the visual impact of the mortar.
Unbeknown to us at the time, the work attracted the attention of a client with an even older, larger and much more complex property we went on to tackle later.
