help -holes in roof trusses

[chickenlicken]

Hello,

My builder's apprentice at the start of my refurb project has just drilled 15-18mm holes in my 120mm roof trusses to run electric cables. They are in almost of the trusses. It is making me feel sick to read online that this may mean my whole roof is compromised. What should I do now?

It doesn’t mean the trusses are scrap & it depends on the size of the trusses & where the holes are. Just tell your builder to fix his apprentices cock up at his own expense & keep a closer eye on him in the future; & possibly get a new builder.

Thanks Richard. Is it easily fixed or will it need an engineer?

 

[Richard C]

No engineer needed, Blob the builder just needs to clamp some steel reinforcing plates either side of the joists than need it; if I were you, I would keep a serious eye on him.

Why would anyone want to put cable through trusses, when it can just go over the timber?

 

[chickenlicken]

it's a mystery. was much more work for him than just looping it over

120mm roof trusses suggests to me that they may be attic trusses.

So why can`t the wires run in the eaves void and then across the roof with the trusses Would it use so much more wire that the volt. drop would be un acceptable

Noseall had a good point, if he is right, then the OP may want to see the link below that will give some idea of what you can do.

You will probably find that any warranty the manufacturer provided is now invalid

But it just makes no sense at all to drill though trusses

As he is an apprentice, you might want to do him a favour and point this out to him
