Hi, Sorry if the subjects a bit of a mouthfull, I'm not sure if they have a short name?
Anyway, after recent high winds some of these units have blown off. I've spoken to the builder (the house is only 1.5 yrs old) and said that I'm not happy at the way they've been fitted as they've been secured with plain nails, the Marley technical brochure say they should be secured with annular ring shank nails seeing as they are going into end grain.
The builder said that they can be secured a number of ways and it's the snow that's ripped them off (even though some of them are near the peak of the roof and nowhere near any snow!!).
Any advice would be greatly appreciated.
Cheers,
Martin
