Lead flashing failure is the most common cause of persistent roof leaks on Borough Green period properties. A25 road vibration progressively loosens chimney pot bedding mortar is the primary accelerant in Borough Green. We replace chimney aprons, step flashings, valley lead and dormer junctions — Code 5 as standard on all exposed positions. Free diagnosis visit. 8 miles north-west from Tonbridge.
Lead is where most roofs actually leak — at chimneys, valleys, abutments and dormers — and split or lifted lead is a common, fixable cause. In Borough Green, the ragstone cottages and railway terraces near the station are where we see it most.
When it is not the answer: If the surrounding covering is also spent, renewing lead in isolation only buys time — we’ll tell you if that’s the case. Read the full guide.
Leadwork usually needs a tower or scaffold for safe access to the junction being dressed. Scaffold is specified for: chimney, valley and abutment leadwork at height - always itemised in your written quote, never a hidden extra, and we arrange it.
Borough Green mixes Victorian ragstone cottages and railway-era terraces near the station with post-war and modern estates, so access ranges from tight terraced frontages to open estate driveways. Pavement scaffold and skip permits go through Tonbridge and Malling Borough Council; allow a few working days on streets like Western Road, Quarry Hill Road, Sandy Lane where space is tight.
A contained, tidy job at the junction being worked; little indoor disruption and no need to be home. You do not need to stay home for external work - we just need power and access agreed in advance.
Lead is dressed and pointed in dry weather so the joints and mortar set correctly. Sitting up on the free-draining greensand ridge, Borough Green roofs dry faster than the valley floor but take more wind exposure along the higher streets.
Borough Green’s the ragstone cottages and railway terraces near the station bring their own lead flashing patterns. Sitting up on the free-draining greensand ridge, Borough Green roofs dry faster than the valley floor but take more wind exposure along the higher streets. Borough Green mixes Victorian ragstone cottages and railway-era terraces near the station with post-war and modern estates, so access ranges from tight terraced frontages to open estate driveways. On streets like Western Road, Quarry Hill Road, that shapes both the fault we expect and how we get to it safely — which is why every Borough Green quote starts with a proper look at the roof, not a phone estimate.
Before we price a lead flashing job in Borough Green, we check the roof properly. Borough Green mixes Victorian ragstone cottages and railway-era terraces near the station with post-war and modern estates, so access ranges from tight terraced frontages to open estate driveways. We trace the fault to its source, note the safe access a street like Sandy Lane allows, and set out the fix in a written, itemised quote. Your work is covered by a written 10-year workmanship guarantee, transferable if you sell, with manufacturer warranties on any new materials on top; storm and impact damage we document separately for your insurer.
Covering TN15 and surrounding postcodes.
Lead flashing work in Borough Green requires correct specification — Code 3 on an exposed Borough Green chimney fails within 10 years. We specify correctly by default.
The apron flashing — front face of the chimney — takes the highest weather loading in Borough Green. Code 5 (2.24mm) minimum. Welted joints on all lap positions. Correctly chased into the mortar joint above.
Step flashings up the chimney sides in Borough Green require soakers under each tile course and correctly-overlapping lead steps above. We install to Lead Sheet Association specification throughout.
Open valley lead on Borough Green properties — Code 4 minimum, Code 5 on steep-pitch high-flow valleys. Welted cross-joints every 1.5m maximum. Correctly lapped under tile courses.
Dormer cheek and apron flashings on Borough Green properties require careful dressing to the dormer frame and underlying tile. Failure at dormer flashings is common on 1970s-90s extensions throughout Borough Green.
If you have a persistent leak in Borough Green that has not been correctly diagnosed, we carry out an on-roof investigation and identify the flashing or tile cause. Free investigation with any repair booking.
We specify the correct lead code for every position — Code 3 is too thin for exposed work anywhere in Borough Green. Every quote states the lead code and joint method. If a quote doesn't — ask.
Lead flashing failure in Borough Green is accelerated by A25 road vibration progressively loosens chimney pot bedding mortar. The housing stock — 1970s-80s suburban estates on Quarry Hill and Nepicar Road — means the majority of lead work we attend in Borough Green is on pre-1940 properties where the original flashing specification was modest and has not been upgraded since.
The most common pattern on Borough Green properties: Code 3 flat-lapped lead installed 10-15 years ago is now splitting at lap joints and admitting water that tracks to a ceiling drip remote from the actual entry point. The correct fix is Code 5 with welted joints and a correctly chased top edge — this lasts 40 years in Borough Green's conditions rather than 10.
