Hi All,
I've just relaid some Marley Malvern(?) pan tiles on my house roof after replacing some damaged underlay felt. The original area of work was 7 to 8 rows back from the gutter line and 13 or 14 tiles wide.
When I refitted the tiles I ended with the tile overlap not being sufficient on all but the top row. Guessing I had allowed the tile battens to sag, when I renailed them, I been back up on the roof to redo the battens and relay the gutter row of tiles.
I've redone the first batten, which had sagged down by about an inch, and relaid its tiles. However, I still have the same problem even with any slack between adjoining tiles taken out. At present the last overlap just reaches its adjacent tile but is short by about an inch.
Anyone got any idea what could be wrong and how to remedy it?
The only thing I can think of, is the some of the tiles I've relaid must be slightly narrower, but if this were the case then I'd expect other rows to have the oposite problem ie too long, but they don't.
Thanks in anticipation.
