Roof Cleaning Services in Newham
Almost every Victorian terrace here has a back addition, and its roof is the hardest working part of the building. The outrigger running back from the main house carries its own small covering, usually at a shallower pitch, sitting directly beneath the main rear slope and taking everything that slope sends down. It also has a valley or a junction along one side where it meets the neighbouring outrigger, and another where it meets the house itself. Below it sits a kitchen or bathroom where damp gets blamed on condensation.
That gives one small roof three separate ways to fail. The covering ponds because the pitch is shallow. And the junction against the main wall relies on flashing that has been there since the house was built. Meanwhile the room below is usually a kitchen or a bathroom, so damp appearing there gets attributed to condensation for several years before anybody looks up. Back additions carry more risk per square metre than any other roof. Nobody looks at them because nothing overlooks them. Rear outriggers were built quickly and have been ignored ever since.
The back addition is where a London terrace visit earns its keep.
Ben's Roof Cleaning provides experienced roof cleaning in Newham with the outrigger covering, its valley and its junctions cleared and photographed alongside the main slopes. Nothing is levered. Tell us what the rear looks like and a price comes free. The outrigger sits directly beneath the main rear slope. It takes everything that slope sends down onto a shallower pitch. A valley runs alongside it shared with the next house. Three separate details can fail on one small covering.
About Newham
Newham is built on Victorian terraces with back additions running from the rear of almost every house, each carrying its own small covering at a shallow pitch. Slate, tile and later felt all appear on those outriggers. Shared valleys run between neighbouring additions. Outrigger additions run from the rear of almost every terrace.

The borough is low and densely built with narrow gaps between the rows. Back addition roofs sit enclosed between two properties, shaded for much of the day and slow to dry at any time of year. Outriggers carry slate, tile and later felt coverings. Yards behind them are narrow and frequently shared. Rear elevations across the borough see very little direct sun.
North London cover is the primary service area for roof cleaning in Newham, taking in the neighbouring boroughs. Terraced housing with identical rear arrangements repeats through that ground. Victorian terraces with rear additions fill the borough. Narrow gaps between rows keep those roofs shaded. Kitchen and bathroom extensions occupy most of those additions.
What a Newham Back Addition Roof Takes
It sits under the main slope. Everything the rear pitch sheds arrives on a smaller covering at a shallower angle, which was never designed for that volume. Its pitch is shallower and sheds considerably more slowly. Damp below is attributed to condensation for years. Original valley linings are lead laid over timber boards. Junctions where three roof planes meet occur on many additions.

The valley alongside serves two houses. It collects from both outriggers, drains through an outlet nobody can see and belongs to neither owner in particular. The addition roof receives the output of the main slope. Parapet walls alongside some additions add a further junction. Nothing about the arrangement drains quickly at that pitch.
The junction is original. Flashing where the addition meets the main wall has generally been in place since the house was built and has never been touched. A shared valley alongside serves two properties at once. Nothing about the main roof explains a marked kitchen ceiling. Outrigger gutters are shorter and block with very little material.

What our customers have to say...
Clearing a Newham Back Addition Roof
The valley is cleared and proved first. It takes from two properties, so treating anything above while it is blocked simply sends more into a full channel. Both the valley and the slope above it are covered. Parapet junctions are cleared alongside the valley itself. Coverage runs from the main slope down across the addition. Three-way junctions are worked by hand rather than washed.
The covering is worked to its material. Slate, tile and felt outriggers each need a different approach, and the pitch is too shallow for anything forceful. Nothing is levered at century-old lead at the wall junction. The outlet at the end of the valley is run through with water. Nothing is levered where lead has become brittle with age.
The junction is photographed as found. Flashing at the main wall is recorded rather than lifted, since disturbing century-old lead rarely improves matters. The outrigger covering is treated according to its material. Photographs record the addition from above. Valley boards are checked where the lead has split. Photographs record the outrigger from the main roof above. Coverage runs across the addition and the main slope together.
How Newham Rear Additions Are Handled
The rear gets the attention it needs. Ben's Roof Cleaning keeps trusted roof cleaning in Newham to a risk assessment drawn up per property, insured throughout, and the outrigger is not treated as an afterthought. The account describes the valley, the slope and the junction. Neighbours sharing the valley receive the same findings. Quotations cover the addition, the valley and the junctions apart.

Neighbours are consulted about the valley. A shared channel means work benefits both, and where both want it the pair is quoted together. Quotations list the addition separately from the main roof. Anybody attending will explain where the damp originates. Findings go to both households where the valley is shared. Nothing on the original lead is dressed or patched. Owners hear whether the damp below is rising or falling.
Kitchen damp is explained properly. Where moisture in the room below is coming through rather than condensing, saying so saves years of the wrong assumption. Neighbours sharing the valley are consulted before work. Nothing on the flashing is dressed or sealed by us. Quotations cover the valley, the addition and the junctions. Findings state whether the lining needs a roofer.

Frequently Asked Questions
What is a back addition roof?
The covering over the outrigger running from the rear of the house, usually at a shallower pitch and directly beneath the main rear slope. Additions take everything. Pitches shed slowly. Valleys serve two houses. Outlets stay hidden.
Why does it cause so many problems?
It takes everything the main slope sends down onto a shallower surface, and it has a shared valley on one side and an original junction on the other. Pitches shed slowly. Valleys serve two houses. Outlets stay hidden.
Is the damp in my kitchen condensation?
Sometimes, and frequently not. Where moisture is coming through the covering above rather than condensing, that gets said plainly. Valleys serve two houses. Outlets stay hidden. Flashing is original. Condensation gets blamed. Neighbours are consulted. Three years suits outriggers.
Who owns the valley between the additions?
It serves both properties, which means it benefits both and belongs to neither in particular. Doing the pair together settles it properly. Outlets stay hidden. Flashing is original. Condensation gets blamed. Neighbours are consulted. Three years suits outriggers.
Will you lift the flashing to check?
No. Century-old lead is photographed as found, since disturbing it rarely improves matters and frequently creates work that was not needed. Flashing is original. Condensation gets blamed. Neighbours are consulted. Three years suits outriggers. Additions take everything.
Can felt outriggers be treated?
Yes, with the method suited to felt rather than tile. The pitch is too shallow for anything forceful whatever the covering happens to be. Condensation gets blamed. Neighbours are consulted. Three years suits outriggers. Additions take everything.
Is the outlet on the valley checked?
It is cleared and proved with water, since a valley taking from two houses is useless if the outlet at the end of it is blocked. Neighbours are consulted. Three years suits outriggers. Additions take everything.
How often should the rear be done?
Every three years. The outrigger collects more and dries less than anything else on the building, so it sets the interval. Three years suits outriggers. Additions take everything. Pitches shed slowly. Valleys serve two houses. Outlets stay hidden.
