A Roofer for Life,
Not Just a Roof for Now
Keep a Roofer in Your Phone
Having work done on your home is stressful. You’re letting someone into your house, trusting what they tell you, and hoping the price doesn’t suddenly change halfway through.
That’s why we keep things straight. We’ll tell you what we’d do if it was our own house, whether a repair is worth doing, and when spending money would be a waste. If we think a repair will last, we’ll say so. If we don’t, we’d rather be honest and recommend a new roof than take your money for a patch that is only going to fail.
We’re not the cheapest roofer you’ll find, and we don’t try to be. Good materials cost money, and doing the work properly takes time — but if we take the job on, we’ll do it properly.
No pressure. No chasing. Never trying to squeeze every penny out of you. Just honest roofing advice from a local family company you can keep in your phone and recommend without worrying.
Still not sure? Watch this short video to see what we’re about.

FLAT ROOF REPAIRS & NEW FLAT ROOFS IN NEW MALDEN
New Malden is a strong local area for flat roof work because there is such a mix of homes, extensions, garages, dormers, porches and older roofs that have been repaired, adapted or added to over time.
We work around New Malden High Street, New Malden station, Old Malden, Motspur Park, Coombe Vale, Green Lane, Beverley Park, Kingston Road, Malden Road, Burlington Road, the A3 side of New Malden and nearby KT3 roads.
A lot of the flat roofs in New Malden are domestic roofs that need sensible advice rather than sales talk.
Some are simple repairs. Some need stripping and replacing properly. Some only look minor from above but have already let water into the boards underneath.
The important thing is working out what is actually going on before money is spent.
FLAT ROOFING IN NEW MALDEN
A flat roof should be judged as a full roof, not just by the covering on top.
The felt, GRP, rubber or liquid system matters, but so does the deck underneath, the falls, the edge trims, the outlets, the upstands, the wall details, the insulation and any previous repairs.
In areas like New Malden, it is common to see flat roofs on rear extensions, garages, dormers and outbuildings where different repairs have been added over the years.
Sometimes a previous repair has done its job and bought time.
Sometimes it has hidden a bigger problem underneath.
The job is to know the difference.
FLAT ROOF REPAIRS IN NEW MALDEN
Not every leaking flat roof needs to be replaced.
A repair may be sensible if the roof is generally sound and the problem is local. This might be a split in the felt, a lifted edge, a leaking outlet, a failed trim, a small puncture, a loose flashing, a minor GRP crack or a weak detail around a wall or rooflight.
The question is whether the repair is likely to last.
If the roof is holding water badly, the deck is soft, the felt is breaking down, the GRP has cracked along board joints, or there are several old patches, another repair may not be the best use of money.
A proper repair should deal with the reason the roof is leaking, not just the obvious wet spot.
NEW FLAT ROOFS IN NEW MALDEN
When a flat roof has reached the end of its life, replacement is usually the more sensible route.
That normally means removing the old covering, checking the deck, replacing rotten or damaged boards, improving weak details and fitting a new roof system properly.
A new flat roof should not just look clean when it is finished.
It should drain properly, finish neatly at the edges, protect the building underneath and be built with materials that suit the roof.
This matters especially on extensions and dormers, where a failed flat roof can damage ceilings, plaster, insulation, lights and internal finishes.
For many domestic flat roofs in New Malden, a proper built-up felt system is often the most practical choice.
FELT FLAT ROOFS IN NEW MALDEN
Modern felt flat roofing is still one of the best options for many domestic flat roofs.
A proper felt roof is not the same as cheap shed felt. It is a built-up system using reinforced membranes, correct preparation, good laps, secure trims, dressed edges and careful detailing around walls, outlets and rooflights.
Felt works well on garages, extensions, dormers, porches, bay roofs and outbuildings.
It is strong, proven, repairable and practical.
The reason felt gets a bad name is usually not the material. It is poor workmanship.
Bad decking, weak edge details, poor falls, rushed laps and covering over old problems are what make many felt roofs fail early.
A good felt roof starts before the top layer goes on.
GRP / FIBREGLASS FLAT ROOFS IN NEW MALDEN
GRP fibreglass can look smart when it is installed properly, but it is not the right answer for every roof.
The biggest issue with failed GRP roofs is movement.
GRP cures into a hard shell. If the boards underneath are moving, if the joints are unsupported, if the wrong boards have been used, or if the deck has too much flex, the surface can crack.
That is why the deck underneath matters so much.
A shiny fibreglass finish does not prove the roof has been built properly.
On older domestic roofs, garages and extensions around New Malden, the structure and boardwork should be checked carefully before GRP is recommended.
RUBBER FLAT ROOFS IN NEW MALDEN
Rubber roofing, usually EPDM, can work on simple flat roofs with clean details and a sound deck.
It is often sold as an easy system because the membrane can be laid in large sheets, but the main sheet is only part of the roof.
Edges, trims, corners, outlets, pipes, wall details, rooflights and door thresholds are where rubber roofs often fail if they are fitted badly.
Most flat roofs fail at the details, not in the middle.
Rubber can be suitable in the right situation, but for many domestic roofs with awkward details, a properly fitted felt roof is often the more practical option.
WARM ROOFS AND COLD ROOFS IN NEW MALDEN
If the flat roof is over a heated room, the insulation build-up matters.
This is common with kitchen extensions, rear extensions, dormers, bathrooms, offices and converted spaces.
A warm roof has insulation above the structural deck and is often the better option for modern flat roofs over living space.
It can improve insulation and help reduce condensation risk when designed and fitted properly.
A cold roof has insulation below the deck and relies more heavily on ventilation.
Cold roofs can work, but if ventilation is poor, blocked or badly designed, moisture can build up inside the roof and damage the timber from underneath.
The waterproof covering keeps rain out from above, but the roof build-up underneath still needs to be right.
GARAGE FLAT ROOFS IN NEW MALDEN
Garage flat roofs are common across New Malden, Old Malden and nearby residential roads.
Many are older felt roofs that have been patched over the years. Some still have sound boards and only need a sensible repair. Others have rotten decking, poor falls, failed trims or water sitting in low spots.
Common garage roof problems include cracked felt, leaking edges, soft boards, gutters pulling away, failed corners and old repairs that no longer hold.
If the deck is sound, a repair may be enough.
If the boards are rotten or the whole roof has failed, stripping and replacing it properly is usually the better answer.
EXTENSION FLAT ROOFS IN NEW MALDEN
Extension flat roofs need proper care because they are usually above living space.
A small leak can damage ceilings, plaster, insulation, lights, paintwork and internal finishes before the roof looks especially bad from outside.
The roof needs good falls, proper wall details, secure trims, suitable insulation where needed and a waterproofing system that suits the roof.
Older extension roofs often have a history of patch repairs, coatings or extra layers added over time.
Sometimes those repairs have bought time.
Sometimes they have hidden the real issue until the deck underneath has suffered.
The roof needs to be judged by its actual condition, not just by how it looks on the surface.
DORMER FLAT ROOFS IN NEW MALDEN
Dormer roofs are small, but they can be awkward and important.
They often leak around windows, cheeks, corners, trims, upstands and joins to other roof areas rather than across the open middle of the roof.
A failed dormer roof can cause damp in bedrooms, loft rooms and plasterboard.
Because dormers are often harder to see from the ground, problems can go unnoticed until staining appears inside.
Dormer roofs need careful edge work, proper details and a roof covering that suits the structure underneath.
COMMON FLAT ROOF PROBLEMS IN NEW MALDEN
The same flat roof problems appear again and again: splits, blisters, cracks, rotten boards, standing water, failed trims, poor falls, blocked outlets, loose flashing, lifting rubber, cracked GRP, failed coatings and old patch repairs.
The visible leak is only part of the story.
The real question is what caused it.
If the issue is small and local, and the rest of the roof is sound, a repair may make sense.
If the roof has failed because the deck is rotten, the falls are poor, the structure is moving or the covering has reached the end of its life, a patch is unlikely to be a proper fix.
REPAIR OR REPLACEMENT
The decision between repair and replacement should come down to condition.
A repair may be sensible if the issue is local and the rest of the roof still has life left in it.
Replacement is usually more sensible if the roof has widespread failure, rotten decking, movement cracks, poor drainage, multiple old patches or old coverings that have broken down across the whole area.
There is no point spending money on a repair if it is not likely to last.
Sometimes a repair is the right answer.
Sometimes it is not.
The important thing is being honest about which one applies.
OUR PROCESS
The process starts with understanding the roof properly.
Photos can help, especially where there is an obvious leak, crack, stain, failed trim, rooflight issue or area of standing water.
If the roof needs checking in person, the important things to look at are the roof covering, the deck, the falls, the outlets, the trims, the walls, the insulation and any signs of internal damage.
From there, the advice should be clear.
The customer should know whether the job is a repair, replacement or upgrade, what is included, and why that route makes sense.
Good flat roofing is not just about doing the visible part.
It is about getting the preparation, details and build-up right before the final finish goes on.

NEW MALDEN FLAT ROOF FAQS
How do I know if my flat roof in New Malden is worth repairing?
It depends on the condition of the roof underneath, not just the leak you can see. If the roof is generally sound and the problem is local, a repair may be sensible. If the decking is rotten, the roof is holding water, or it has already had several patch repairs, replacement may be the better long-term option.
Why does my flat roof keep leaking even after it has been patched?
Usually because the patch has only covered the visible problem, not the reason the roof is failing. Poor falls, rotten boards, failed trims, cracks around details, blocked outlets and old repairs can all cause repeat leaks. A proper inspection should look at the whole roof, not just the stain inside.
Is felt still a good option for flat roofs in New Malden?
Yes, when it is fitted properly. Modern built-up felt is strong, practical and repairable, which makes it a good choice for many garages, extensions, dormers and outbuildings. Felt usually fails early because of poor preparation, bad decking, weak details or poor workmanship, not because felt itself is a bad system.
Why do GRP fibreglass roofs crack?
GRP is rigid, so it does not cope well with movement underneath. If the board joints are unsupported, the wrong boards have been used, or the deck is moving, the GRP surface can crack. The roof may look good when first finished, but if the base is wrong, problems often show later.
Should I upgrade my flat roof to a warm roof?
If the flat roof is over a heated room, such as an extension, kitchen, bathroom, office or dormer, a warm roof may be worth considering. It can improve insulation and reduce condensation risk when designed properly. It is not always necessary over unheated garages or outbuildings.
Can a garage flat roof be replaced without changing the boards?
Sometimes, yes. If the boards are dry, firm and in good condition, they may be suitable to keep. If they are soft, rotten, delaminated or damaged by leaks, they should be replaced before the new roof covering goes down.
What causes water to sit on a flat roof?
Water usually sits because the falls are poor, the roof has sagged, the outlet is badly placed, or the roof has been built up over time with old layers and patches. A flat roof should still be designed to drain. Standing water does not always mean instant failure, but it can shorten the life of the roof and expose weak details.
What photos are useful before booking a visit?
The most useful photos are a clear picture of the whole roof, close-ups of the leaking or damaged area, the edges and trims, any outlets or gutters, and any staining or damage inside. This usually gives enough information to say whether it looks like a small repair, a possible replacement, or something that needs checking in person.
