PROJECT SPOTLIGHT
LISTED SLATE, PART RE-COVER & LEADWORKS
This project was on a Grade 2 listed building to repair/replace a failed lead gutter & valley system. This failure has caused significant damage inside the property.
After attempts to repair, including our inspections and visits, we concluded that this was, in fact, beyond repair, and the areas around the lead gutter & valleys were also showing significant signs of water ingress. This water ingress and certain conditions had allowed a fungus to grow throughout an area of the property, causing more internal damage.
In order to preserve the building in the best way possible, the roof works had to take place, which also protects the building's future.
We started this project with James and his team at JDB Professional Access Ltd, giving us the best access to this very difficult-to-reach part of the roof. This was imperative to our work and schedule.
We then stripped all the lead sections, exposing the damaged and rotten timbers. Then Lee and Sam from Haye's Joinery worked on repairing and replacing any timber work that was needed. This included materials from a local independent timber supplier.
All timber works completed, we started stripping the old Welsh slate roofs. Care and attention were taken in trying to reclaim as many of the original slates as possible, but due to their age and position on the building, we only managed to reclaim approximately 600 in total.
Now 450 qty of these are seen back on the roof with new copper nails to fix them. We had to select carefully to ensure the strength & longevity of the reclaimed new covering.
We made attempts to outsource reclaimed Welsh slate for the rest of the roof, but this was exceptionally challenging because of the quantity we needed and also the quality we required.
With this result, the clients were happy to install a new Welsh slate (Celtic) from the Penrhyn slate quarry, with a nominal thickness 0f 9mm BS EN 12326. These slates have a thermal T1 cycle. Along with the approx. 450 reclaimed Welsh slate that we have re-instated on the roof we also installed approx. 1,430 new Welsh slates. With other supplies coming from our local SIG roofing branch.

The lead gutter has been replaced with code 6 lead, now reinstated with correct bay sizes and lead sections. A lead roll was installed at the foot of the valleys to ensure direction of water and to allow the expansion of the lead. The valleys were reinstated with code 5 lead, all lead has been oiled with patination oil to preserve as manufacturers specifications. Any lead has been fixed using Calder copper nails to ensure longevity and security. The lead has been installed on Calder AF1 building paper this is to protect the underside of the lead and timbers.
All ridge tiles on the hips and ridge of the property were reclaimed and reinstated.
Throughout this project, we have done our best to ensure current building standards & regulations have been met where possible. We have sourced the best materials for this project to ensure the longevity and security of this building.
Our aim has been to preserve this building and contribute to its grand appearance for many years to come. We would like to thank the clients for allowing us to be part of the building's long history & all trades that were part of this extremely rewarding project.
OTHER PROJECTS
FLAT ROOF REPLACEMENT

The old flat roof system was hopelessly falling back into the bottom of the main roof, causing damp and water ingress issues.
We stripped the old covering and had to alter the timbers to correct the direction of water travel away from the building.
Once we had achieved this, we covered it with a 1.54mm EPDM rubber system. We installed new fascias and gutters to give the new roof a clean finish and, more importantly, to carry the water away.

REDUNDANT CHIMNEY STACK REMOVAL

The customer has carried out extensive work inside the property and has no use for this stack any longer.
We were asked if we would leave it as low as we could for them to manage the rest of the internal removal after.
When the stack was completely removed, we added a new breathable felt membrane along with new battens. We re-tiled it and added reclaimed ridge tiles to blend the roof and work better with the existing roof.
