Thanks. Can I ask how that right hand edge should have been finished?

A friend of mine has just had an extension roof redone. The flashing on the right hand side of the velux appears to come above the new tiles. Does the install in the picture look right?

Thanks for the reply. I have just lifted the lids and they are GRP, they were only installed about 15 years ago when the property was converted. What are the options? Thanks again.

We have 2 septic tanks with 1200mm concrete lids that have 3 lifting points. We wish to extend them up 1m to allow us to level the land. Can we lift the lids off, fit the concrete extensions and refit the lids? If the tanks are plastic are they designed for the extra weight? Any advice would be much appreciated. Thanks.
