Roofing
Roofing is 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 work — your average roofer is not recommended for work on the house roofs.
The conservation status report goes into detail about the qualities and benefits of the materials, lines and profile of the roofs on Templemere.
This section looks at roofing for houses, garages and their connected elements.
House roofs
Any new roofing work needs to be approved by TRSL due to its architectural significance and disturbance on the estate.
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 and T2Ys respectively.
Most original roofs have come to the end of their lives and many homeowners have used our trusted suppler Roles Broderick Roofing. They have proved themselves to be technically capable to produce high quality roofs and have carried out replacement roofs on both the L1 and T2Ys successfully.

Verge fascia
Traditionally painted white and low profile, TRSL accepts that due to modern requirements for ventilation and insulation the verge fascia needs to be larger.
Roof verge fascias on both L1 and T2Y properties need to be grey aluminium regardless of 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.
-
Material
Both asphalt and torch-on felt (advised) materials are common for flat roofs today and so it is easy to find professionals to install and repair them.
Make sure the correct lead flashing is installed along with the correct size aluminium fascia trim, and keep the roof line to original height.
Do not let flat roof material wrap over the edge and into view.
-
Edging: L1
On L1 kitchen and porch elevations, a 50mm strip of aluminium wraps around the edge of the flat roof barge board.
White 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 for the fascia boards and match original sizes.
-
Edging: T2Y
On T2Y porches, a 50mm strip of aluminium wraps around the edge of the entire flat roof.
For barge boards please only use wood painted white gloss and match original heights 200mm (from base of aluminium edging).
-
Edging: Garages
A 50mm aluminium edging must be used.
Repair or replace barge boards with wood in three 140mm high horizontal lengths. They are to be painted in British Standard Rhino Grey gloss.
Guttering and drainage
T2Y’s are the only properties that have visible guttering. The square-section folded metal gutters are typically bespoke and would require a custom solution for replacement.
They have generally held up very 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 relatively low cost.
Gutters are painted as part of the rotating Templemere painting maintenance schedule.
When replacing downpipes ensure they follow the exact position of the originals.
-
L1
On L1 houses there is no visible guttering. There is a shallow gutter over the kitchen leading to a down pipe within a brick pier and a gutter wholly across the main roof leading to the same downpipe.
-
T2Y
T2Y gutters are painted square-section folded metal. Painted British Standard Rhino Grey Gloss. Dimensions are 110mm wide by 80mm deep.
Downpipes are XXXmm round section and brackets are both painted British Standard Rhino Grey.
T2Y gutters are painted as part of the painting maintenance schedule. -
T2Y: Porch downpipe
T2Y 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). This maintenance is the homeowners responsibility.
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
Fascia panels on L1 houses extend on all four sides of them just above the first floor windows and on the T2Y houses again just above the first floor windows and on the gable ends. Originally they were are asbestos cement board and most of them have come to the end of their material life.
Should you need to replace or repair your fascia boards TRSL has recently conducted a thorough study on materials that best reflect the original asbestos boards and are cost effective for installation and ongoing maintenance.
Replacement solutions are currently being reviewed by TRSL due to the need to find materials that are suitable for current painting requirements and upkeep.
-
L1
L1 The panels are a prominent feature along the top edge of the elevations and run all the away around the property.
It is important to note the lack of visual joins and the finishing details on the bottom of the fascia and where the top meets the roof under the verge edging. Avoid horizontal joins as these will alter the angled impression originally designed.
-
T2Y
Here the panels sit under the guttering and while smaller it provides an important architectural feature. The fascia also has no joints and is finished on the base with simple white edging.
-
T2Y gable end
On T2Y gable ends, please match panel widths to the existing (approximately 4ft wide) and use butt joints with invisible fixings. Avoid horizontal joins as these will alter the angled impression originally designed.
-
Fixtures
It is advised that any hole drilled or cut edge is adequately sealed to improve the longevity of the material.
Ensure all fixtures and fittings are concealed and invisible when finished.
