I have just moved into an elderly but well-built bungalow.

The cement infill at one corner of the roof has brocken away.

As it is easily reachable with a ladder I want to fill it myself.

I would like to use a ready-mixed product.

I am in easy reach of Screwfix and Tool Station.

Is it feasible? If so which product?

How much do you need?

To mend very small patches, I have used Fischer Express Cement Premium
- it comes in a tube, to be used with a standard sealant gun.

It's made with some kind of resin rather than water, so it sets quickly,
and is rock hard in a short time. However it may be entirely unsuitable
for what you want.
