chocccie Posted April 24, 2009 Share Posted April 24, 2009 I'm going to use some reclaimed mechanical terecotta type tile to roof a store room adjacent to a house. Can anybody tell me the minimum pitch required please?Thanks Link to comment Share on other sites More sharing options...
Northender Posted April 24, 2009 Share Posted April 24, 2009 Depends on a few factors.Where you are situated.Is it going to be on a wall facing the prevailing wind.When I restored our Bread Oven the existing pitch was only 22.5 degrees.I kept the same angle but laid underfelt and used newer interlocking tiles.Not been a problem so far.

BIG MAC Posted April 24, 2009 Share Posted April 24, 2009 30 degrees would likely be a safe bet Link to comment Share on other sites More sharing options...

Can anybody tell me the minimum pitch required please? [/quote]The primary determinant of the minimum roof pitch is the size of the roofing unit (then the amount of overlap, then the degree of exposure ...)So, going back to my college books [:)], I find:Plain tile, 265x165 - 35 degrees. Single interlocking pantile, 380x260 - 22.5 degrees. Double interlocking Roman tile, 420x380, 17.5 degrees. Slate, 430x380, 17.5 degrees.HTHCraig Link to comment Share on other sites More sharing options...
