Bad roofing job: how should I proceed?

[David001]

A certain building company, which claims to be professional, has left me with a shoddy porch hood.  I paid them one third at the end of the first day of work.  I have not paid them the remaining two thirds.

 

Please have a look at the worst examples of their work.  (There are a total of 32 similarly serious flaws.

 

I have asked another roofer to look at the porch, and a carpenter is soon to look at the woodwork.

 

PLEASE could I have people's opinions as to how to proceed?

That looks like dogshit.

 

Flashing should be up behind the wood cladding, so that needed cutting back, lifting away, and the lead offered up behind it.

 

Woodwork and ridge tile etc is abysmal. 

 

Shocking how anyone can say they can do a job like this for someone, when they clearly have zero clue what to do or how to do.

 

2/10 at best, more like a 1/10 though.
