"What's the minimum pitch for plain tiles on a rafter roof?"
Plain tiles need a minimum 35-degree pitch to shed water properly. Below that and you're asking for trouble — water gets driven under the tiles in heavy rain. If you're at 30 degrees or under, you want interlocking concrete tiles or a fully bonded membrane system. And always double-lap your courses.
Always verify to current regs. On-site conditions may vary.
Yes. If your job involves roof work, the checklist flags fall protection PPE, harness requirements, scaffold inspection, and method statements for working at height. Always comply with WAH Regulations 2005.
Any roofing job — tile replacement, flat roof repair, full strip and re-roof, lead work, fascia and soffit, guttering. Describe the job in detail and the checklist adapts to your specific work scope.
Absolutely. After your checklist is generated, tick the items you need and generate a shopping list sorted by category — tiles, fixings, lead, membranes, tools. Share it with your merchant or apprentice.
