Roof Opinion on Possible House Purchase - Rosemary Tiles Circa 1910

[cmillar7]

We could do with some opinions. We viewed a house and are considering putting an offer in. The house was built circa 1910 and had an extension in the 90s.

At the viewing I got some photos from above and inside. Is there anything to be concerned of here? We assume the old part of the roof needs a membrane and the battens replaced. But outside of this, do you think there is anything else that we should be concerned of such as the rafters? Also what is the white stuff, could it be mould?

Also we are trying to budget for this along with other things like re-wiring and a chimney replaced/repaired. Does anyone know how much we should allow for this work?

The roof looks similar to our 1920s build, but you have no torching.

My parents bought a 1920’s build in the 80s and the survey said the Rosemary tiled roof was nearing the end of its life. The same roof is still on 40 years later and has no leaks and has needed no maintenance.

Our survey 15 years ago said that our 1920 s build rosemary tiled roof was nearing the end of its life but it’s still fine. It’s very dusty due to the torching gradually failing, but other than that it’s watertight.

The roof in your photo has the odd chipped or delaminated tile (which could be replaced) but otherwise looks fine to me.

OP,
Buy it - its a great looking house in a great location, & if what you show & tell is the extent of work needed then the cost of the work in terms of the total purchase price is not significant.
Given there's no leaks then dont mess with the roof coverings - get some more years out of the tiles etc.
Clean all gutters & all valleys - only allow roofers who use roof ladders - & for the chimney stack rebuild a scaffold is required.
Come back here if you do buy it?
