For most people, having a roof is like having a circulatory system. You don’t think about it until it stops working. If you’re a homeowner and your roof is average, you can go years not thinking about it – that is, until something goes wrong. Then you hear the roofer’s language and feel a bit confused.
Pointing is the mortar between roof tiles. You’ll find it at the top of a roof, where the ridge tiles run and where the roof tiles meet the surrounding masonry. The stuff takes all the frosts and winter’s freeze-thaw cycle that we experience and as a result it becomes either solid or flaky. When it gets to this stage, it allows entry to water that falls onto the roof space, and, over time, this deterioration causes it to fail.

What about that stuff they use around chimneys, skylights, and at the joins between the roof and abutting walls? That’s known as flashing. It takes the form of a sheet of lead, metal, plastic, or other similar material and is placed at the joins between the roof and things such as chimneys, skylights, or abutting walls.
If you’ve got the first two, the third is probably hiding from you. Felt, like an insect, is underneath your tiles, and you may have neglected it for years or maybe never even seen it. It’s there to provide a secondary line of defence against water, the outer layer of protection beneath your tiles. It catches all the drips from the under tiles that a well-laid felt should not allow to escape in the first place.
