Cement around a chimney isn't wrong It's just a cheap alternative and doesn't have a very long life spand in keeping out the water as lead is normally is the case in this circumstance of securing the gaps around ur chimney I'm happy to assist if you if you would like a quote if need on ur property

If there is no flashing you will find multiple leaks in the loft at somepoint...there is an alternative simulated lead that can be used sometimes.

Hi , yes Iv seen a few jobs with cement around the chimney it’s as if they’ve done a cheap job , with cement this will crack in time , just needs an airline crack and water gets in and once frost comes it blows the crack bigger, the same with lead after a long time this can form an airline split and needs patched up , But 9 times out of 10 Lead is used, in your case I would just leave it till you start seeing cracks .
