The Mill House



The Mill House is a Grade II listed building located within the picturesque village of Ripley in Surrey.

The house was built out of red brick, that was once colour washed, it has a low pitched, hipped slate roof and consists of two floors with corbelled end stacks. The pitched roof terminates into a leaded flat roof area, which houses a centre dome skylight, that is situated above the first-floor landing. The flat roof area appears to have leaked for many years, with various attempts to repair the roof over the years, till the eventual occurrence of internal damage, through water ingress.

We believe the main reason for the leaking roof was the original depth and fall of the drainage channel. The original channel was only 25mm deep, which overflowed when the water could not be dispersed quick enough around the base of the dome and eventually found its way into the property.

As previously mentioned, various repairs were carried out, but none actually corrected the problem. Large amounts of silicone were also used to try and seal the dome glass, which ended up causing a condensation problem due to poor air flow. Our main purpose was to eradicate the leaking roof and carry out the remedial works to the internal ceiling area of the property.


The first process was to try and determine the exact extent of the internal damage, by removing some of the lathe and plaster ceiling. Prior to carrying out the works, the internal décor was protected with polythene sheeting. Unfortunately, the opening works highlighted quite severe damage to the structural woodwork of the roof and the deck above.

Access to the roof was gained via fixed scaffolding, to enable the external works to be carried out. The dome was removed, due to the structure not being self supporting all the glazing required to be removed. The original lead covering was removed the roof was re-instated to include adjusting the height and channel falls. The roof was then re-leaded using code 6 lead sheet. The dome was fully refurbished and re-instated. The internal works commenced with the structural timber being replaced. The ceiling was then repaired using lime plaster, secured onto new lathes. The area was then decorated to return the landing area back to its former glory
