White roses turning pink at the edges

[Marthaclematis]

... can you help as to suggest why this has happened? I don't know the name of the rose, it was a gift. I've had it over 7 years and its never done this before. Its not unsightly; the frilly outer edges are turning pale pink. Odd ??

It may be water damage I get this on my whites.

It's down to heat and temp according to this: My White Roses Are Turning Pink | eHow.com (although I haven't time to read it through properly)

My small white patio rose has the outer petals turning pink, but it hasn't happened to my Iceberg

Thanks, my icebergs are fine too. What is water damage Pipkins? Could it be overwatering? I do water very well.
