slight leak on house roof

[ash1212002]

we have a slight leak coming from the end of a pitched roof into the corner of the bedroom ceiling, there is no damage to the tiles and cannot see anything to show how the rain is coming through

if i apply some of this stuff would it do the job? from what i have gathered the acrylic stuff is better than mastic

If you can't see where it's leaking from.....how will you know where to apply this stuff? Have you had a proper look up there? Getting up close and personal to the roof will show up defects that aren't noticable from the ground.

is it at the bottom of the roof,if so it could be the bottom of the felt is defective from age/weather.may need to renew the eaves felt/dpc.just a guess from the info given

i've had a proper look thinking of applying the stuff around the area where the leak is coming from

attached is a pic from the area the leak coming through to the corner bedoom

This is a common problem. Check the gutter and RWP inlet as well.

the joint between our property and the neighbour's property is mortar cement

i personally wouldnt do anything in way of a make shift job as it could just move the problem along the roof and youve wasted your initial cost.get a ladder up there and slide a tile up off the bottom row and look at the felt.

i shall have a thorough look again once the weather is better

Looks like a 70`s re-roof job , there was Loads of £ made then by slapping on tiles in place of knackered slates- then someone in the row wouldn`t waste their money @ the time and when it was done later you have a " not so good " join like you`ve got . As you suspected, the felt has been holding the ingress of water back for maybe 30 years ..it never was good , just takes years to show. A secret gutter between the 2 houses would be the best fix. Maybe the neighbour would contribute .

to have the secret gutter fitted what would the cost be? i take it the other option which i guess would be the cheap option, would be to remove the tiles re-felt the area?

if that is the problem then its quite a simple fix and too expensive

 

[ash1212002]

simple fix yet expensive

do i have any other options? to replace the felt?

sorry,NOT TOO EXPENSIVE.
