A question (or two!) for the roofers out there
Discussion
Something has grabbed my curiosity and I was hoping the roofing experts on here might be able to help.
Is it ever acceptable to tile a large roof (with no skylights or chimneys or other features, just a plain run) by starting at both ends and meeting in the middle? Say, as result there's a row of "trimmed" tiles that run from ridge to gutter right down the middle of the roof?
The trimmed tiles are say 75% width, so probably still have both fixings.
I Googled BS5534 and it led me to believe this is a no no. (AI actually said "a cowboy job"
)
Not just the fact it looks a bit odd, but Mr Google reckons you risk compromising weather tightness, mechanical fixing and how the tiles slot together. I'm guessing that's dependent on the tile.
Is Mr Google just being a bit dramatic, or is this really shoddy workmanship?

No it s not , start from the left or the right depending on what handed you prefer to work , if you must use two roofers working towards each other measure it through carefully , strike it out with lines top to bottom to ensure you meet in the middle .
I didn't really mean the start points...I meant the run of trimmed tiles that are at the middle of the roof. Surely this must mean somebody got their calculations right and is a bodge?paulwirral said:
Sounds like someone wanted to get both ends bedded up or if it was hipped get the hips tiled in and ridged off and just fill in the middle ?
Either way they ve miscalculated , probably on the half tile
That's what I thought. Will the trimmed tiles in the middle of the roof (other than looking a muddle) really risk the issues that Google suggest? And, does it really contravene BS5534?Either way they ve miscalculated , probably on the half tile
Thanks for your replies by the way
Is is this work on your own house you’re worried about or a job you’ve noticed? Exclusively right to left, if you’re right handed is the order or the day, it’s more comfortable nailing, bring the tiles/slates along at a raking angle so you’re not sat on top of your work; plus the way the interlocks are formed on tiles compels you to lay them this way, otherwise you’d have to lift up one tile to slip the other under it.
With something like a plain tile or slate you could feasibly work from both ends and use a tile and a half or wider slate to compensate for any discrepancy in bond where they meet but I can’t see any reason why you would want to do this.
Pics would be interesting as said above.

Thanks for the reply. It's a friend's house. I'm not wanting to worry them if trimmed tiles in the middle of the roof is acceptable (why would I?)With something like a plain tile or slate you could feasibly work from both ends and use a tile and a half or wider slate to compensate for any discrepancy in bond where they meet but I can t see any reason why you would want to do this.

It just struck me as odd, and then when I Googled it it worried me! Can't really photograph it without worrying my chum.
