roof leak along joint between terraced property

[ash1212002]

Approx 2 years ago the roof was leaking between the joint of our terraced property and the neighbours roof, the roofer rectified this with a bed of mortar

We are now experiencing the above again and guessing that the mortar has deteriorated in some places as it is a small leak

I have figured it is from the joint as I see the trail of the leak along the joint in the loft

I have obtained a few quotes but the roofers have given different views to rectify the problem which has confused me further

they are as follows

1. leave the remaining mortar there and give it a once over with further mortar, ensuring no holes/gaps are missed
2. same as 1 but also apply bituminous mastic on top of the mortar
3. same as 1 but to also apply lead flashing or ridge tiles

What option do you recommend that I go with? I would appreciate your views!

Post a pic if you can.

A skin of mortar will just peel off.

Slapping tar on mortar is a short term fix.

Dont know what you mean about the lead.

thank you for the reply

lead flashing or flash band i think was mentioned...

I shall take a pic and upload tomorrow

Flashbands another quick fix.

What are they quoting?

 

[ash1212002]

£235 to apply further mortar and then to apply the flash band between the joint between my property and the neighbours

Would ridge tiles be a better option?

 

[Alastairreid]

A proper bonding gutter would be your best bet.

I wouldnt waste my money on any of the other options.

 

[ash1212002]

bonding gutter has been suggested but the neighbour is not prepared to assist in any way in terms of cost and shall hold me liable for any damage and for further problems should they arise..

is there a next best option/solution?

 

[Alastairreid]

Daubing cement and flashband down the roof is causing damage in the long term.
Ridge tiles down the seam is awful looking and more expensive than a proper bonding gutter.

If this is a terrace then why have you not got the same slates/ tiles.

Well another slate roof with tiles on thats leaking.

 

[ash1212002]

Is the leak being caused by my neighbours property due to the slate tiles?

The neighbour is not interested in assisting in any way

 

[Alastairreid]

Was the roof leaking at the join before you got your side tiled?

As far as i can see its the roofer who tiled your roof who has caused the problems.

the roof was like that when we purchased the property
