Posted By Robert Higgins I would be grateful to receive specific practical advice as to an appropriate method to clean vally gutters. We propose to use a valley gutter walker (a framework on wheels in side which the cleaner will walk in the gutter). The roof is a fragile roof. Thanks in anticipation!

Posted By Charley Farley-Trelawney Robert Is it possible to do it from ground level, there is a specialist machine on the market that will go up to 30 metres,and will suck house bricks at the same lift? You could have a spotter in a MEWP guiding the person at ground level thus eliminating the need to access the gulleys on foot, again, depending on the distance from the edge if that were not possible, what about a lorry mount 'cherry' and slowly do the cleaning from the cherry using high powered suction, again, no need to directly access the roof. Just a couple of thoughts although difficult to be precise without further information. Charles
