I've had two roofers around.
1st roofer quoted £1250 to replace in EPDM rubber. Didn't mention stepping.
2nd roofer has quoted £1250 fibreglass or £1600 Code 6 Lead. Either option would have a step introduced.
Attached is a photo of the leaking box gully. The board is shot (bit spongy to walk on) so time for proper repair (the flashband was my attempt to keep the Saturday downpour out after the previously flexacryl repair failed). The gully is just over 4m long as doesn't really have a fall in it currently as water pools under the Velux.

2nd roofer categorically said, even if I don't use him, do not get an EPDM roof. Says that over time, with the wind the slates will move slightly and wear through the rubber. Also, any slipped slates would risk puncturing the rubber when they fall. I can understand this logic and so I'm discounting roofer 1 and looking at the options roofer 2 is proposing.
Online both seem to be regarded for box gutters and so I'm confused about which option may be best. Happy to pay for lead if that the better option.
Would a fibreglass solution need a step?
Is Code 6 the correct lead for this length of run/application?
Any thoughts, experiences or horror stories?
Thanks
If me, code 6 with step
Step will allow for thermal expansion and contraction of lead.
As with any job only as good as person who is fitting it.
2nd person sounds honest with you, do they have a social media presence are they listed as a company to check their longevity as a business.
Thanks, yes they're on social media and appear to have been used and recommended by a few people in the village (judging by village FB group).
It's an old house and the roof isn't the best but didn't suck his teeth or mention any other parts.
Any thoughts, experiences or horror stories?
I fear that a crock (not gold) will be underneath and other stuff will surface too.
Ask them to have a look at that hip iron and whatever it's screwed into, it looks like the lowest ridge tile is slipping
On the plus side, very few slate repairs are apparent
Is that all your roof or neighbours too?
Would expansion joint(s) be easier than a step in the lead?
Just chucking stuff into the mix - not a roofer but deal with them in my line of work.
All our roof.
Hip iron was secure from memory when I was up there, but I'll double check whilst I have access. Thanks. The rafters and joists don't look too bad from inside the loft but as you say, when the leads lifted I'm sure something else will present itself 🙁

Why are you bothering with all this shit, that's why you hire roofers, so they can worry about it. Point at the issue and say "fix this".
Hire a decent local roofer (he'll be the one that can 1. give a proper written quote and 2. will need to schedule you into his diary) and there won't be horror stories.
It is pretty reasonable to want to know what materials they are suggesting using.
There is loads of information out there:
In that guide code 6 is recommended for a box gutter with a maximum length of 2.2 m. So one step seems bang on.
For an extra £350 lead seems the right choice.
Not sure I would trust the longevity of an expansion joint.
Thanks Robola
I've got written quotes from the roofer but he's offering two options. He seems to prefer fibreglass, where as everything in my limited knowledge says do it in lead. Can only assume he doesn't want to lug 30+kg up there.
