The main house on this project I re-roofed back in September 2010, the property a grade II listed building this was a complete re-roof for Carter Construction. We worked alongside the contractors of the construction company, us stripping the roof tiles, battens and felt and the carpenters doing any timber remedial works and insulating the roof voids. All sound existing tiles were set aside for re-use as this was a grade II listed building, great care was taken in saving the tiles as they are expensive to obtain replacements.
The out buildings to the house in Little Wittenham Oxfordshire where clad in handmade clay peg tiles and we set aside all sound tiles and fittings for re-use. Some timber and gable end repairs were needed but generally the roof was in good order. The work was undertaken so that were possible the weatherproofing of the building was maintained due to the unpredictable British weather. Once the roof was repaired and rafters de-nailed the vapour control membrane was laid on and fixed. The new pressure treated battens are then put on at a set gauge to suit the tiles.
With all the preparation work completed tiling using the existing along with new replacements to match the tiling moved along quite smoothly. Once all tile work was completed the final cement work and lead flashings needed were completed, restoring the buildings back to their original glory but maintaining the character to comply with the grade II requirements for renovations.
Due to the size of this project and the volume of images that were taken we have arranged them into a gallery so you can select the pictures you want to enlarge and view. You can also start at the beginning of the gallery and navigate through the main pictures to confirm the level of my craftsmanship in completing large work like this contract.
This is the extension that came up through the garage roof that I did the GRP Flat Roof for located in Abingdon Oxfordshire. The images show the extension roof being felt, battened, tiled and with a straight lead chase flashing, with mortar work to verges and ridge tiles. The standard stepped leadwork flashing would have looked out-of-place so close to the roof angle so the builder and client asked for it to be straight and it worked.
The roof felt using high quality products from Marley, battens are pressure treated for long working life, in place ready to accept tiles at the correct gauge.

The finished cement weathering to the tile edge providing a neat finish that will set to a Portland cement light grey colour.
The ridge tile in place ready as a guide for fitting the remainder, you can also see the UPVC fascia boards used which is not only decorative but virtually maintenance free, they just need a clean periodically.
Replacing a built up felt roof above a kitchen extension using the Sealoflex system.
A small flat roof above the tiles was showing signs of deterioration and with the location and ease of access, it wasn’t practical to cover in the usual felt or lead for security reasons with lead being a commodity that is frequently stolen.
The Sealoflex system was recommended, after completely preparing the site a base primer was applied and the first coat of re-inforced membrane base coat. Once that has cured the main top coat is applied providing a durable waterproof top coat similar in colour to using lead but obviously it can’t stolen.
This gallery will confirm the handwork applied and the Sealoflex system for flat roofs is becoming a popular alternative to using lead. This is a very good product as the life expectancy can be extended by an application of a maintenance coat. It is also cold applied no heat or flame is required so no risk when being used.

A large job where I applied the felt, battens and tiled the barn roof plus lead work coming in behind the carpenters as they completed their parts of the project. I will always remember this project as it was in extremely cold weather and the work took about three weeks to complete my part of the contract.
This was a barn conversion for a local builder where a new cut roof was put on and I fitted all the roof tiles. These were a handmade clay tile to keep the authentic look in the surrounding area of East Hendred Oxfordshire. The roof is ready now for all the bonnets to be bedded on using sand & cement.

This is the garage of the barn conversion with three velux lights in the back roof. I made the decision to tile all perimeters, bed verges and ridge tiles while the weather allowed us to then I could just fill in and tile around the windows.
The roof on this barn conversion is almost complete. The weather was particularly cold when this was done so the mortar work can only be applied above a minimum creation temperature.
Just finishing off the mortar work while the weather breaks (briefly).
This image shows the barn roof complete, as you can see the tiles were blended so they had to be mixed at a certain ratio to make the blend look right. This roof had only bonnet and valley tiles so the battens had to meet all the way round for the bonnets and valleys to marry in with tile levels. It made it harder with the addition of roof light windows too, so this takes some thought and lots of tape measurement work! add in the very cold weather when this project will be very well-remembered.
This porch roof needed stripping off and replacing. A new timber barge was replaced and the rafters repaired. I put new breathable membrane felt on, new treated battens and replaced the existing clay peg tiles making up numbers from a reclaim merchants.
Reclaimed hog back ridge tiles were used to finish, as you can see, a tile under cloak was used in place of fibre cement as this was a listed building and it kept its original state. Lead stepped flashing was put into the wall abutment it was originally a cement fillet but over time this fails and cracks allowing water ingress. Lead is a better and a sounder process lasting for many years to come.
This is the porch roof completed all, tiled in with the reclaimed hog back ridges bedded on with sand & cement. The stepped lead flashing is all that is in need of pointing and another customer was left happy with my workmanship.
Felt, batten, tiling, leadwork and sealoflex flat roof. I have already posted about the work carried out in my Flat Roof category and now I can detail and show the tiled roof part of this project.
This is an extension roof with plain clay tiles and three velux roof lights installed. The roof had some intricate detail with various abutments and other roofs meeting together. I started by felting and battening the roof and getting the verge tiles bedded on, with the first ridge on it could all be pointed in neatly and flush. The velux windows were fitted so I could tile and cut around them.

There isn’t much of a run to get into this roof and with so much detail it takes time to get around to each area. The windows had to be installed seperately and cut around before the next one can be completed.
The other side of the roof has another detail. A lead gulley had to be put in as it went down into the existing house. This required a carpenter to form a timber substrate to which the lead work was formed and fitted. If you look at the verge above the gulley, that runs into the verge of the new roof which required a lead detail too.
The verge tiles and end ridge bedded on with sand & cement and pointed to a neat flush finish.
Views of the finished work before removing the scaffolding, the overall roof work the client was very pleased with and it reached their full expectations of the aim of the extensions in not only creating space but also using available daylight via the Velux roof lights.
New extension roof, I applied the felt, battens, tiles, lead work and sealoflex flat roof system. Extensive extension work using a number of materials and applications to weatherproof the property
This was a single storey extension roof in Whitchurch near Woodcote. The job consisted of me doing a site visit for the building contractor and advising on quantities of materials and suggesting what system to put on the flat roof areas and in the gulley.
This shows the bonnets being laid and tiles cut in to suit. We are working our way across to meet the valley. Note there is a flat roof on top and a lower porch to engage. For a small extension the tiling work was quite intricate.
These are a handmade clay tile that are similar to an old clay peg tile. Once the felt was laid and the battens fixed and gauged to meet round at the same level on the hips and valleys, the tiles could be laid on to the battens and the bonnet tiles fitted so the tiles marry round at the same level.
The client was concerned about having too much lead on show for reasons of theft so I advised a sealoflex system to put on the top flat roof which is a reinforced polyester system very tough and flexible. To extend the life of this flat roof an application of a maintenance coat can be applied
This gulley has been lined in code 5 lead and has been formed to have two steps in it to so the lead is in long enough pieces for expansion & contraction form various weather temperatures.
The lead is formed down on the ground first being bossed, cut & welded to suit the gulley width and roof angle and then it’s put into position on a geotech lined gulley to minimise abrasion on the timber. Doing it in the correct fashion minimises the stress on the lead reducing the risk of premature splits and failure to weatherproof the property.
The extension roof was tiled and cut around the flat roof porch. This porch has a sealoflex single ply membrane on it for durability and excellent weatherproofing properties.
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..

New Extension roof involving felt, battening, tiling, leadwork and the sealoflex flat roof system. This new flat roof extension is a single ply membrane called Sealoflex, it is a reinforced synthetic rubber. All the joints are taped and then a sealing primer is applied to prevent the liquid from seeping and soaking too much into the boards.
Finishing off the sealing primer ensuring the edges are properly coated.
A pink base coat is applied with a polyester reinforced membrane put into it then allowed to dry. From this image you can also see the extensive roof work that I was involved with on this project.
A top coat which is UV resistant grey in colour is applied. This is a very good product as the life expectancy can be extended by an application of a maintenance coat. This is also cold applied so no heat or flame is required. View 1 of the finished roof.

The garage flat roof here has come to the end of its life and I was asked to replace it with a new 3 layer felt roof system. Click the images to enlarge for more detail.
This is the garage completed with a torch on mineral felt. I used a high-grade felt with minerals as a top coat. A first layer is laid loosely to allow for movement, a second layer
torched on with a burner going opposite way to first layer then a last third layer with edge details torched on to finish.
As you can see the finished roof in a mineral top coat surface. Compared to the original lime stone chippings on the roof shown below, the roof I supplied and installed it’s a lot neater looking and a more durable finish.
