The following query was received by a Norac Member:
Do you have any statistics regarding asbestos content in roof sarking felt? Our surveyors habitually sample sarking felt but I think the last positive result was actually several years ago (which make me wonder whether that was the result of a false positive/cross contamination?).
Do NORAC members usually sample this and do they ever find any asbestos content?
The response can be seen within the attached document.
