The edge of a pitched roof as it meets the gable end is called a verge. Tiles on the verge are often mortared to prevent rain and wind from getting underneath the tiles. Dry fix options for verges are also available from a number of manufacturers.
When the mortar on a verge crumbles or disappears then there is a risk of leaks from water being blown into the roof space. The roof verge will need to be rebedded with mortar. This is generally a straightforward thing to do.
Rebedding A Roof Verge – How Much Does It Cost?
This is normally a one day job for two people. The cost will be around £460-£510 which will be for:
- £150-£200 -Access tower
- £260 – Labour (2 people for 1 day, 1 x £160 + 1 x £100)
- £50 – Materials, This include mortar and potentially replacements for any tiles or slates that break during removal of the old mortared verge.
The tiles at the edge of the gable will need to be stripped from the roof and cleared of mortar as will the ridge tile above them. They are then rebedded on a mortar bed and then repointed to achieve a neat finish. There are different types of verge finish.
When a slate verge is being replaced then it will be repointed as the slates are secured by nails rather than mortar. Repointing a tile verge without removing the tiles and rebedding them on a mortar base is pretty much a waste of time.
Mortar can be coloured to match the roof covering. Colours include slate grey, black, brown and red.
A traditional verge is built on the fascia.
Verges can also be undercloaked when a fibre cement board projects beyond the fascia and the tile verge is mortared to this.
Modern houses are often built with dry verge systems. Whilst these do look neat they may look out of place on a traditional roof.
