This is a new extension roof with plain concrete tiles applied to it. A very rewarding job as it was for a disabled child who got to have her own room with a special hoist to allow her into the bath safely. The roof had bonnet tiles on and it went into a stone wall abutment where the lead flashing work weathered in the roof to the main building.
Two roof lights were also installed making full use of natural lighting. The patch of tiles left out are for access to the lead flashing and to get to the ridge tiles ready to complete after the roof light has been fitted..
Lead flashing work installed ready to point in with cement mortar
Unfortunately it happens and it has to be dealt with quickly before the weather gets into the supporting structures.
This gulley was lined in lead, it is on someone’s house in Wantage town centre Oxfordshire. The lead was stolen so I was asked by the clients insurance company to find an alternative to replacing the lead. I advised on a Sealoflex system as this adheres to almost any substrate.
I started by removing the bottom three course of tiles to expose the gulley. I cleaned the gulley and found the boards to be in sound condition. I then applied the Sealoflex system onto the boards and up the brick work.
This adheres to brick work extremely well and seals to a finish therefore avoiding lead to use as a cover flashing to stop potential further theft. This is one of the higher end premium products on the market and will last in excess of 20 years if applied correctly. The product life can be extended by routine upgrades which I do offer clients
Lets see if their sticky fingers steal this protection. Click to enlarge the image for more detail.
New porch showing the tiling in progress and the installation of the lead flashing for weatherproofing the structure. Work was completed to the clients satisfaction in two days.
This image shows the stepped lead flashing into a wall abutment. The lead is cut into sections to allow for expansion & contraction created by the elements. It is marked and cut to suit the angle of the roof and brick mortar lines. The lead is then bent to slot into the mortar line that has been chased out to a 25mm depth. Lead wedges fix it in place and then a lead sealant or mortar mix is filled into the mortar chase.
This method has been the traditional way to prevent the ingress from various weather and gives many years of service in doing that. Click the image to enlarge for more detail of the craftsmanship employed.
On this complete re-roofing project at various stages it’s necessary to complete the leadwork required under the building codes of practice to weatherproof and protect the fabrics of the roof. Approximately 1 day to complete the hand work to create this back gutter to the existing chimney.
This image shows the new lead back gutter installed and ready to finish slating around the chimney. This piece of lead was measured and cut to suit the angle and fall of roof then welded so it could slot into place. This is a highly skilled process and if not done correctly it will put more stress on the lead, it will not be thinned by beating and bossing in the wrong places therefore lasting for many years. A separate cover flashing is installed over the back and into the brick mortar. Click the image to enlarge and view the craftsmanship employed in more detail.
The new tiled roof that I installed required extensive lead-lined gullies to prevent rainwater access and deterioration of the supporting fabric. The leadwork is hand dressed in the traditional manner using code 5 lead which was bossed and hot lead welded to seal all joints. The work was completed to the clients satisfaction in approx 4 days.
This image will show you all the traditional hand work skills required to form the lead into the contours of the roof, click the image to enlarge for more detail.
Here you can see examples of the standard of my lead work as part of this complete re-roofing project The work took approximately 1 week to complete and involved the replacement and re-lining of the gulley between the roofs, supplying and working the new roof hip replacements in traditional lead work.

This is the lead being installed to one of the hips. Getting the wood rolls at the right height off the slates makes the difference from a bad job to a really nice looking correct lead hip.
This is the lead roll hips completed. A wiping of patination oil is applied over the lead to prevent white staining running down the tiles. It’s pointless going to all that hard work and skill and ruining that look when it rains!
This ulley was originally felted and in a poor state. The boards under the felt had perished from years of leaking. We completely stripped out the existing felt and timber substrate and replaced with new treated marine ply and then installed new code 6 lead separated into bays using wood cored rolls.
