New Roof advice / option please

[MrNice]

Hi All,
We are in the process of having a new roof fitted. Sadly the work does not look right, we have not paid yet and the roofer came back and says that due to the diff heights of the neighbours roof; the best he could do was to add some silicone under the tiles. Should he have used bonding gutters ?

This just doesn't sound right for a 6k roof, please give your thoughts on the attached pictures.

Many thanks

Pretty poor on several counts to be honest .
The small cuts next to the chimney don't have CDRs , they should have used doubles cut to size .
Lead wedges holding the stepped flashing in place are proud of the surface and should be tapped back to allow pointing neatly or smooth continuous lead mastic. As the step flashing does not extend around the front of the chimney there is a point exposed which could let water in
The joins to your neighbours is a total mess. Your slate would never had joined properly as they are differing sizes.
A simple bonding gutter would have dealt with this neatly . There's probably more but i only gave it a quick glance. If scaffold is up , don't let it go you are going to need it

 

[MrNice]

Many thanks for your response. As I have found myself from 2 mins on here and online.

A bonding gutter should of been used! Together with the other list of faults, clearly a very poor job.

Have to work out where I go from here? As they had an attempt to put right and told me this, the results in the pictures is the best they can do.

Thanks

it can be done without a bonding gutter.. just not by your guys.

you could try sending pictures to technical support of the company that produced the cement fibres..

 

[MrNice]

I don't know who produced them, they removed the original slate and replaced with thase.

 

[datarebal]

Is there a piece laying around ? If so post at pic of both sides

Unfortunately I am struggling to find anything positive to say about it.
They will learn to improve their standards if people stop paying them!

I was trying to be kind to the op

 

[MrNice]

I have not paid them, they have offered to send 2 of there senior roofers. The pictures are the result of my having complained once allready and them sending the same chap to rectify, 2 weeks later. Plenty of chance to have sent competent and capable staff, rather than try to fob me off with an attempted bodge (silicone under the slates).

Understandably I have lost all patience with them, following many mishaps and very poor management. I shall be seeking the services of another firm to rectify.

I will try to get the name of the manufacture of the slate.

Many thanks for your help

It a fibre cement tile! looks like marley eternit

 

[datarebal]

That was my first thought ,
Gut tells me it may be cembrit Jutland ..
But might be totally wrong

That's garbage & will give you and the neighbours endless problems.
There is no place for silicon on a slate roof (mock or real, makes no odds)
Make sure you keep all the emails or texts.
See if their 'senior roofers' mention the cuts (as someone else mentioned, for mock slates you use doubles cut down to 1 and a half so you can get a rivet in)- if they don't it's a slam dunk for small claims and trading standards (basic competence, installing to Mfr instructions).
Did they use copper nails (recommended) or galvanised (cheaper)

 

[MrNice]

Once again thanks for the feedback & help, they left a bag of galvanised, I did clear up some copper nails. So think a mixture has been used, possibly copper at front with galvanised at the rear.

Feel I will have to get an independent in to assess the work, in order to answer if doubles have been used.

Many thanks

It's easy to see from the pics that they haven't used doubles. Galvanised nails are not as long-lasting as copper but (long as they used 30mm length) not an outrage- the design life for mock slates is either 25 or 30 years, galv should manage that. The half slates at the boundaries are a big fat no, they'll slip or fail quite early (5-10 years)

Are they a legitimate professional roofing company? The quality of the work suggests otherwise. Hope it all gets sorted to your satisfaction.
