Little help please

Would anyone care to tell me the sequence of construction of a cold pitched roof (40 degree) with tiles? Or maybe a link to a website that show it. A virtual beer will be credited to your account.

Its a roof with vents.

A 'cold roof' is one that has insulation fitted below it and needs to be ventilated. EG; a loft with insulation laid between the ceiling joists of the rooms below.

A 'warm roof' is one that has insulation fitted over it and does not need to be ventilated. EG; a flat roof with insulation boards laid over the joists and felt laid fixed to the insulation boards.

To answer the OP.

1. Structure - rafters, ties, struts & beams or trusses.
2. Underfelt Sarking - laid with a sag between rafters/trusses. Starting from the bottom and working to the ridge. Each run to be lapped over the preceeding one.
3. Cross batten with timbers to support / fix the tiles to.
4. Tile. Again starting at the bottom.
5. Ridge tiles.

Additional to the above will be any flashings/weatherings and ventilation. These will be dependant on actual design needed and will vary.

ETA: the above applies to England & Wales. In Scotland the underfelt sarking is replaced with timber board sarking over which underfelt sarking is laid.
