Dear All - please can you assist. I have a flat roof (hot torched felt - i think - top surface of felt is silver in colour almost looks like lead), into which i want to insert a suntube (12" diameter). As the flat roof was only replaced 5 yrs ago my thoughts are that i could fit the sun tube by dressing over it and the existing felt. I am keen to learn what the existing felt is (I have a digital image but cannot attach to this thread) so that i can match it up OR i thought i could dress it with lead, using lead adhesive.
Any ideas? THANKS
