Sorry if this is the wrong section, I'm not entirely sure what this falls under. My Dad's a joiner/carpenter, and often has to design roofs. He's had his roofing book since his apprenticeship 45 years ago, so it's tatty and falling to pieces. I want to buy him a new one, found this in Waterstones Goss's Roofing Ready Reckoner: Metric Cutting and Sizing Tables for Timber Roof Members, but I'm not sure it's the correct sort of thing? Electrics are my thing, joinery is his so I don't want to waste money buying him something that's not relevant!
I realise this isn't DIY related but I don't know who else to ask.
Thanks.
