Roof verge mortar repair.

Be careful when lifting mortar to the top part of the roof if it is possible get an extra hand. Over four years ago i repaired about two metres of roof verge using a mix of 4 sharp sand to one of cement. Dry fix options for verges are also available from a number of manufacturers. I used this mix because as a complete roofing novice i happened on to this site.

Scoop some mortar into an old bucket and use a trowel and mortarboard to apply it on areas where the old mortar was removed. Use the trowel to butter and smooth the mortar make sure it is even and leveled. 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 repair specification included for stripping off the large format interlocking concrete tiles at the verges renewing the fibre cement undercloak and cutting out and replacing tantalised roof batten ends affected by wet rot.

Rebedding roof verges by making necessary repairments a cement mortar is known as roof bedding. The good news is it is still as solid as a rock. Its job is to keep a lash on the roof tiles. Bear in mind that as time will pass the bedding will gradually wear out.

Sand and cement being the only materials apart from the odd tile if any are broken on removal its not a big job and done correctly you should not have any problems for quite a while. Tiles on the verge are often mortared to prevent rain and wind from getting underneath the tiles.
