Gable end (dry ridge?)repoint or upvc what's best?

Moved into an end terrace house and had the dry ridge repointed 3 times in 2 yrs it's cracked yet again and I'm scared birds maybe in there the loft is a large store room.

Has anyone else had the upvc put in?

Or do i need to keep having repointed?

Depends on your roof covering.

Slate or tile?

There are modern alternatives on the market.

Happy to take a look and advise on best course of action.

It's a slate roof

I'd say rake out all the old mortar and use roofing putty.

Its permanently flexible so will never crack or fall out.

hi contact me on 07707400154 can tell u the best thing to use and show u the product

had a upvc company knock on the door quoted £185 for each side??

wondered why you would only have one side

sounded a con so walked away
