Roofing
All replacement roofs and associated parts must have the same appearance as the originals.
Roofs are an important part of the overall aesthetic of the estate and, more importantly, an integral part of your property. The roofs are architecturally significant, unusual and therefore repairs and replacements require specialist roofers. The conservation status appraisal goes into detail about the qualities and benefits of the materials, lines and profile of the roofs at Templemere. This section looks at roofing for houses, garages and their connected elements.
House roofs
Today, with modern materials and techniques, aluminium sheets in pre-coated colours can be folded to replicate the original weathered copper or zinc colours on the L1 (4-bed) and T2Ys (3-bed) respectively. Original roofs are starting to come to the end of their lives and many owners have used Roles Broderick Roofing for replacement roofs, who have installed high quality roofs on both the L1 (4-bed) and T2Y (3-bed).

Verge fascia
Traditionally painted white and low profile. Due to modern requirements for ventilation and insulation the verge fascia needs to be larger. Roof verge fascia panels on both L1 (4-bed) and T2Y (3-bed) properties need to be grey aluminium regardless of the roof material.
Flat roofs
Porches and garages both have torch-on flat roofing. It is a flat roof covering solution that involves three layers of modified bitumen (felt) melt-welded onto the roof surface and each other with the use of a blowtorch to create an impenetrable, waterproof seal.
Please pay particular attention to the aluminium strip edging ensuring it is re-used or matched to the originals to maintain a unified appearance across the estate.
Roles Broderick Roofing Ltd are TRSL’s recommended contractor for roofs.

Material
Both asphalt and torch-on felt materials are common for flat roofs today so it is easy to find professionals to install and repair them. Please make sure the correct lead flashing is installed along with the correct size aluminium fascia trim. Please keep the roof line to the original height or neighbouring roofs where connected will not be able to drain.
Please do not let the flat roof material wrap over the edge and into view.
-
Edging: L1
On L1 (4-bed) kitchen and porch elevations, a 50mm strip of aluminium wraps around the edge of the flat roof barge board. White fascia/barge boards should be 140mm high each with a 40mm spacer gap for the inset string course to match the windows. Please use wood, painted white gloss or white uPVC for the fascia boards and match to the original sizes.
-
Edging: T2Y
On T2Y (3-bed) porches, a 50mm strip of aluminium wraps around the edge of the entire flat roof. For fascia/barge boards please only use wood painted white (gloss) or white uPVC and match to the original height of 200mm (from the bottom of the aluminium edging).
-
Edging: Garages
A 50mm aluminium edging must be used.
Guttering and drainage
All visible guttering and drainage should have the same appearance as the original.
T2Ys (3-beds) have bespoke square-section folded metal gutters and these will require a custom solution for replacement. They have generally held up well considering their age with the only weakness being the angled joints.
Leaky joints can be repaired with a variety of off-the shelf materials at a relatively low cost. Gutters are painted as part of the rotating Templemere painting schedule. When replacing downpipes please ensure they follow the exact position of the originals.
-
L1
L1 (4-bed)
On L1 (4-bed) houses there is no visible guttering. There is a shallow gutter over the kitchen leading to a downpipe within a brick pier and a gutter wholly across the main roof leading to the same downpipe.
-
T2Y
The T2Y (3-bed) gutters are a square-section folded metal painted British Standard Rhino Grey Gloss. Dimensions are 110mm wide by 80mm deep. Downpipes and brackets are both painted British Standard Rhino Grey. T2Y (3-bed) gutters, brackets and downpipes are all painted as part of the rotating Templemere painting schedule.
Guttering in the wrong style, colour or material e.g. plastic, is not approved for installation.
-
T2Y: Porch downpipe
T2Y (3-bed) properties have a concealed downpipe running next to the porch and living room window. This pipe is fed by a drain on the porch flat roof. This grate is known to have a restricted flow due to leaves and sticks during winter months. Regular maintenance is advised here as well as where the concealed pipe joins the soakaway (behind the grey panel). Please do not re-route pipes on the exterior of the porch.
-
Soakaways: Front garden
Soakaways that drain the roadways are cleared about every two years to forestall flooding.
Those which drain houses under their lawn or garden are the responsibility of the relevant owners.
-
Soakaways: Rear garden
Garden soakaways are the responsibility of the homeowner(s). They are often shared between a few properties with the soakaway crate in one garden.
Have a look at the Plans page for general position and reference.
Fascia Panels, Gable Ends & Roof Window Cleaning
All replacement fascia panels, gable ends and associated parts must have the same appearance as the originals.
Fascia panels on L1 (4-bed) houses extend on all four flanks just above the first-floor windows and on the T2Y (3-bed) houses just above the front and back first floor windows with cladding on the gable ends. The original material used was Chrysotile Board, which cannot now be properly prepared for painting due to the presence of asbestos. TRSL recommend these all be replaced in either of:
1) Painted marine plywood with all joins filled prior to painting white and with finishing details to match the original design. These replacements will require ongoing painting and should have an expected life of 20-30 years dependant on how much exposure they get to the elements.
2) To remove the need to paint, white pre-coated aluminium sheets (RAL 9010 Ref: Clean White) can be installed using secret fixings so joins do not stand out. This should have a life of 30-50 years dependant on how much exposure they get to the elements and will only requiring washing down periodically with water.
Both of these options will have a similar white and flat finish, with only subtle visible joins on the aluminium option, and will provide a consistent and uniform look across the Estate to tie-in L1 (4-bed) and T2Y (3-bed) houses and keep to the spirit of the original Span design. So a consistent and uniform look is maintained across the Estate, any other material used will need to have a similar white and flat finish with joins at similar intervals to the aluminium option. The joins of any other material used must not stand out more than the aluminium option joins.
-
L1
On L1 (4-beds) these panels are a prominent feature along the top edge of the elevations and run all the way around the property. It is important to note on the original design the lack of visual joins and the finishing detail on the bottom of the fascia and where the top meets the roof under the verge edging, which should all be replicated when using painted marine plywood. Please do not use horizontal joins when using painted marine plywood as this will alter the angled impression originally designed.
-
T2Y
These panels sit under the guttering and, while smaller than on L1 (4-beds), they provide an important architectural feature. The original fascia design also has no visible joins and is finished along the bottom edge with simple white edging.
-
T2Y gable end
When using painted marine plywood on T2Y (3-bed) gable ends please match panel widths to the existing (approximately 4ft wide) and use butt joins with invisible fixings. Please avoid horizontal joins as these will alter the angled impression of the original design and please note the finishing details on the bottom edge, which should be replicated.
-
Fixtures
It is recommended that any hole drilled or cut edge is adequately sealed to improve the longevity of the material. Please ensure all fixings are concealed and invisible when finished.
