Garage roof rafters treated or not

[mwkenna]

I am about to purchase the timber for the roof trusses/rafters on a new build garage. I will be putting a metal roof with dripstop on. Is there a need to buy tanalized do you think? Or will standard rough sawn be OK?

Thanks,
Mark.

Being a garage roof, it should have good ventilation, so why bother?

I was thinking better safe than sorry. Woodworm, any condensation, etc...

Its not too much more expensive for tanalized. If the general consensus on here is just go standard then I will.

Thanks

In fact, I just priced it up and there is £15 difference in the whole roof between treated and untreated. It doesn't really bear thinking about for that price difference!
