Captain, we have a problem. There's a leak in the roof!

Posted on 1st November, 2021

A roof is there to keep those inside the building warm and dry. Or at least it should be.

 

We have a roof that is letting water into the building. That might just be unfortunate were it not for the fact that someone was paid to find the cause and "sort it out" earlier this year.

 

Here are some photographs of it taken from a ladder last week.

 

The building is three storeys high so getting up there is not something one wants to do unless one has to. We just had to see if we could spot what the cause of the leak might be.

 

 

 

 

 

Valley Gutter North Side

 

It's an almost 50 year old roof that appears to be clad in the original concrete roof tiles.

 

We have been advised ( based on these photos ) that the deep valley gutter suggests that it may have been refelted at some point in the past using a second layer of batons.

 

An inspection from below, inside the loft, also suggests that the felt below the valley tray may not have been replaced at that time. The tray currently sits on top of a very brittle layer of felt that we assume is part of the original build.

 

The rotting timbers supporting the valley tray, where they abut between the trusses, also suggests that the water ingress is coming from the top half of the roof or valley gutter and has been doing so for many years.

 

The following video is a record of this inspection which was carried out during the first week in October 2021. It was shot a couple of weeks after a rain laden major gale had driven in from the North West in late September.

 

We only noticed that the freshly painted kitchen ceiling was now watermarked with pink staining when doing a final clean and inspection in early October.

 

Prior to this we had been lead to believe that the roof had been repaired earlier in the year.

The following video is the final one in a series recorded after the one above. These have been taken while trying to establish the cause of the leak and the severity of it.

 

A temporary containment solution using tarpaulins and drip trays has been installed to better monitor and contain any ingress until the roof can be fully repaired in the spring of 2022.
