1. Concrete roof tiles guidance
I have come across some interesting design guides on Forticrete‘s website, free to download.
Forticrete is part of the Concrete Tile Manufacturer’s Association (CTMA) and therefore has access to a number of useful data sheets on various topics relating to the construction of roofs.
The association supports the Roofing Industry Alliance, whose main aim is to increase the quality and reliability of roof construction.
Documents are available on the following topics:
- Changes in rafter pitch
- Dry fix ridges
- Eaves detailing
- Mortar bedded hips
- Mortar bedded ridges
- Party wall junctions
- Side abutment detailing
- Top edge abutment detailing
- Valley detailing (parts 1–3)
- Vent tiles and pipes
- Verge detailing (parts 1 & 2)
- Surevent: condensation control in roofs
2. Clay roof tiles guidance
The Clay Roof Tile Council has a technical library full of similar information. The CRTC collectively represents over 90% of UK clay roof tile production. Its members are Dreadnought, Marley Eternit, Keymer, Redland and Sandtoft.
The Clay Roof Tile Council’s online library covers information on topics including:
- Repair and maintenance
- Design specification
- Material specifications
- Health and safety
- Handmade technologies
- Machine made technologies
- Wind uplift calculations
- Quality control
- …and a very handy little glossary of terms.
