Taylor and Klass type fascia gutter systems
These are characterised by the clean exterior metal lines of the outside fascia but have the actual gutter concealed behind it.

The issues are: In heavy rains, or when the gutters become blocked, or age, or rust, or were poorly constructed, rain water overflows onto the soffits, into walls and wets framing, insulation, GIB board, flooring and carpets. If the framing is only H1 or UTKD the framing will decay as it is not treated against decay when wet.

Walls with narrow soffits, gutters that connect with walls, those with upper roofs discharging onto them and valleys pose even higher risk of leaking, wetting the framing and causing decay.

Problems are:
A - many have a series of holes punched through the gutter at 20 or 25. When the water level reaches this it travels down onto the soffit and into the walls wetting the framing, GIB, insulation, carpets and flooring.

B - When the gutter is blocked with debris or the rain event is extreme the water level rises and overflows inside onto the soffit and into the walls wetting the framing, GIB, insulation, carpets and flooring.

10e - The gutter lip is often separated allowing water in

10 - across the bottom to 5c often rusts out dropping water onto the soffit and into walls.

Taylor have introduced overflows fitted at 21c but often these are not cut down below 25 so leak onto the soffit before they start operating.
Leaf guards can be fitted however these make things worse as organic matter composts so moss can grow and cannot be cleaned.

Other defects are shown later.

Sure any gutter can be blocked by leaves and debris. But only Taylor and Klass direct rainwater onto soffits and wet walls. External gutters overflow safely out into the garden.
Sure any gutter could be poorly installed but only Taylor and Klass direct leaks from defects onto soffits and wet walls.

So what went wrong?
Taylor outside trim is set on an angle so when they are joined at corners are a development. This takes skill. These have been cut square so have left a gap. Rain water gets straight in.

The valley is a Vee lower in the center than the two sides. This lowers the depth of water before it overflows onto the soffits.

The valley extends into the gutter blocking it.

The leaves are Natives which don't easily decompose so fill up the gutter blocking rainwater from getting to the down pipes. Leaf guards will only make it worse as these block up the gutters even more and composting debris is difficult to clear away.

Taylor Fascia blocked down pipe and overflow

I removed some of the leaves blocking the down pipe, overflow and gutter.

Native leaves amongst others are effective at blocking Taylor Fascia gutters. This causes rainwater to overflow onto soffits, into walls and wets framing, insulation, chip board floors, carpets and GIB linings. It can be serious when framing is only H1 or UTKD.

Time slides by and well meaning landscaping grows above the gutter line. Trees drop leaves which roofs collect and leaves get blown down into the gutters.

If this was a normal external gutter the owner would see the water cascading over the gutter onto the gardens and clean them out. With Taylor and Klass this overflowing water is dropping onto the soffits and making its way into walls doing damage.

We can blame the tree, or the owner for failing to trim the tree or to clean out the gutters. The difference though is if this was an external gutter there would be little consequence when the external gutter got filled and blocked with leaves. No damage would be done.

Not with Taylor and Klass. The gutters may need cleaning 3 or 4 times a year with deciduous trees and more so with Oak, natives and palms as these leaves don't seem to compost for years. That means a lot of muck in the gutters. But even then any small amount of leaves will send rainwater overflowing inside walls.

The overflow shown to the left of the outlet is a typical Taylor after thought add on. But its design does not deal with leaves. They block it as easily as the outlet. No use at all. This particular gutter has a rib about 2/3 the way up with overflow slots in it set below the height of the overflow cut out. That means the gutter leaks before the water level even gets to the overflow level. Its all but useless.

All these defects lead to rain water dropping onto soffits and into walls. Sure maintenance will help but from the ground everything looks okay. Owners and maintenance people without any understanding of Taylor and Klass fascia defects will not even bother to inspect this so in time walls get wet and framing decays. No-one is prepared to inspect off ladders with OSH conditions so these are ignored in the name of safety.

Issue is when products age they must be designed to deal with the consequences until repaired.

Basic engineering 101. External gutters rust as well. The difference is when they rust rainwater leaks out the bottom safely into the garden. But not so with Taylor Fascia.

This recent purchasers builders report to their credit noticed rust in the gutter and recommended a rust primer and paint. It would accordingly last another 10 years. Rust primer does not fix rust pitting that have broken through.

What is the issue?

This Taylor Fascia gutter system has a 0.55 thick Zinc Alum internal gutter. ie considered heavy duty. BUT it is in the sea spray zone so cannot be used as salt oxidizes the Zinc and pits the steel until failure.

The gutter is two stories high. There are no trees nearby so previous owners would have no reason to climb a ladder to inspect or to clean gutters. 'Out of sight out of mind'. From the outside the colour steel Fascia is in good condition so why even think 'what's inside'?

The new owner has noticed two rooms have wet carpets. Constantly. In heavy rain it gets worse but it never dries out. To them its leaking without rain.

Yes it was. The gutters have not been set with the correct fall to drain water to the down pipes. Water is ponding. Salts are rusting. Gutter pitted and holed so the ponding water slowly drips onto the soffits. The two rooms have no soffits so water leaks straight into the wall framing. The remainder of the house has soffits.

On inspection four more areas of pitting were discovered and had wet soffits despite no rain for a few days. Two had mould.

Invasive tests were positive.

The owner contacted us to get overflows installed and conduct Invasive tests in case they had serious problems. The house as built in approx 2000 at the height of the UTKD era.

The builders report included this global statement regarding weathertightness. 'Without invasive testing ie (cutting holes in the cladding) it is not possible to determine the full weather tightness of a building'.
The owner did his research and discovered Moisture Detection who use Mdu Probes for invasive testing. No cladding would be ruined. Tests are done from the inside. Five tests confirmed good news. The framing had been treated with boron to a level higher than the current H1.2 so is effective against decay. All samples extracted were in good condition.

The gutter can safely be replaced or repaired without fear of consequential damage to the framing. Overflows would not help this time. Invasive Testing news is not always bad.

Taylor Fascia incorrectly set out
Negative soffit

This Taylor fascia has been set against the framing so when the cladding was installed it did not fit behind it so water can run down the metal casing and in behind the cladding.

Why blame Taylor then? Isn't it more to do with cramping more homes on limited size sections than a defective gutter? And who left the hole in the corner?

The point is the wall framing is now decayed. How is it to be fixed? It is nonsense to simply replace the decayed framing. No council will allow this to be rebuilt as is as it cannot ever work.

I have included it in Taylor issues as the Taylor is buried into the cladding.

Taylor Fascia Soffit has collapsed.

This Taylor Fascia system has been poorly installed and instead of rain water overflowing safely into the garden it has overflowed at every rain onto the Hardies soffit board until it became brittle and collapsed.

The owner has repeatedly sprayed Exit Mould but it comes back within a few months.

Look for this on your home. By accident the breakout has reduced the water leakage into the two bedrooms below as some of the overflowing rain water dropped into the garden.

This is a direct result of a defective installation and defective design. The expected failure leaked onto the soffit and into walls.

No stop end to divert rainwater from the apron into the gutter

Taylor Fascia incorrectly set up for cladding thickness so trim buried into the plaster.

Taylor Fascia gutter not secured back to trim.

Three issues on top of the defect Taylor Fascia overflow onto soffits and into walls. What the three extra defects do is worsen the incidence and amount of water getting into walls.

A previous owner must have been alerted to the leaks as someone has slipped a fake stop end under the apron and attempted to divert rain water to the gutter. But the fake stop end was not slipped up behind the cladding so water still gets in.

The Taylor Fascia connects to 40mm Insulclad with 5mm of plaster. Although the Taylor Fascia system should never have been allowed to be used it should have been set out 50mm and have a stop end to divert rainwater into the gutter and to protect against weather behind the end. No and No.

The gutter was poorly fitted and has opened up along the top which allows rainwater onto the soffits.

The result of this poor Taylor Fascia installation

The Insulclad plaster has cracked due to continual wetting which has reduced the cementitious material to brittle dust which has cracked and become loose.

The framing below has decayed and requires removal.

Expensive for the current owner. Obviously this has been slowly happening since construction 25 years ago so has passed through several owners. Are you the unlucky one?

In the meantime to keep the rooms healthy a diverter flashing and cap has been installed and RotStop injected to sterilize the walls. This has enabled the current owner to delay the bigger expensive decisions.

Taylor Fascia defective connection to wall.

No stop end to Taylor Fascia has caused wall framing to decay.

Typical completed Taylor Fascia installation to plaster wall. The issue is the Hardibacker and Stucco is 30mm thick so the apron flashing needed to be turned out to divert rain water into the gutter. The Taylor Fascia was incorrectly set up at installation and fitted hard up to the framing. It needed to be shorter so it could be flashed properly. But as it penetrates the Stucco it cannot be effectively sealed.

This detail would have leaked from day one of construction.

But if the owner had Mdu Probes they would have known the first rain they had. Then they could have claimed and got it fixed. Now they are out of time and the consequence has grown to all the framing below the two rooms has decayed. This is over a tiled bathroom and extensive entrance way so will be very disruptive and costly. The owners also have to deal with two more of these also built wrong.

Moral here is to undertake Invasive Testing and install monitoring now.

If any of the owners had installed monitoring they would have been alerted to the problem and got the builder back then and there. Or reduced the purchase price to cover the cost of repairs. Ongoing monitoring would have proven it was corrected or not.

Why wait 22 years before you pluck up the courage to find out.

This came to us as a purchasers builders report recommended invasive testing. Lucky they did otherwise they may be bleeding by now. At least this owner purchased with knowledge. But the previous owner lost a bundle here.

Taylor Fascia issues
Water ponding
Valley failure
Poor workmanship

This could be what is protecting your million dollar home. The gutter is falling away from the outlet with water ponding 20mm deep. The home is close to the sea and beginning to rust. Valley has been cut into the back of the gutter lowering the threshold for overflows. Underlay is short. Taylor Fascia internal corner poorly formed. Valley is partially blocked which allows water to overflow along its length.

Placing any reliance on this sort of detail is miss-founded. These defects were only discovered when the owner replaced the kitchen and found the wall framing had decayed. Kitchens hide leaks as you have no access to them.

Install probes now. At least you will find out what is going on so you can make informed decisions. 
Taylor Fascia gutter leaks:

General note: This webpage shows some common deficiencies with Taylor and Klass style Fascia gutters.
Taylor Fascia (and Klass Fascia) are responsible for unexplained leaks coming out ceiling down lights and water dribbling out of windows. Even with large soffits. The defect is the Taylor and Klass fascia design puts the gutter on top of the soffit so any defect leaks into the building. In heavy rain, or when gutters are blocked, or installed poorly, or age, water overflows and runs onto the soffits (if there are any), gets into walls and wets them. What you see coming out the down lights or windows is but a small part of the full wetting inside the walls.

Wet walls can wet the carpet, GIB and insulation. You may even see these immediately after rain.

The bigger concern which could end up costing a lot of money is wet walls could mean the framing is decaying. If your home was built with H1 timber or Kiln Dried framing it won't have resistance to decay.

Moulds could also be growing inside the walls. The insulation could also be wet resulting in colder rooms. Many homes we visit have decay at the ends of window sill liners, swollen skirting boards and damaged carpet. GIB linings may be wet and soft.

Excessive mould can develop into health issues especially those with immune deficiencies and asthma.

Explaining some of the typical defects
I include some photos and explanations showing defects with Taylor and Klass style Fascia. Keep an open mind as most Taylor Fascia installations have more than one defect. If you have experience with different defects please send your story so I can add them to the list so everyone gets the message.

Has the Taylor Fascia already caused damage to your home.

Before we go any further I want to drum in this message. Your first consideration must be: 'has the building been damaged'.

You may have only just discovered your Taylor Fascia is defective. Your home may already be 20 years old so could have been leaking all that time. Framing hidden inside the walls could already be decayed.

You may have already tried some things which have not worked. Now you are searching for better advice. The first step is to get Invasive Tests done to check the condition of the timber framing hidden inside the walls.

We install moisture probes. See The Invasive Testing will determine whether work is required to fix the flooring, framing, insulation, GIB and window liners.

Invasive testing will also find out whether you are lucky and the framing is properly treated and not decayed. This has a big bearing on what repair options you need to consider to keep your home safe and healthy. RotStop treatment can be added to kill decay and prevent further damage.

Is the Taylor Fascia actually worth repairing?

The adage is 'the only good Taylor Fascia is the one on the trailer going to the tip'. If the Taylor is rusting or has too many defects and approaching the end of its life it may be best to cut it loose. Spending good money on something beyond repair is not good planning. So once you have the invasive test results and have confidence in the condition of your house you can then start investigating how wrong is the Taylor Fascia gutter system. Repair or replace. Its your option. It will depend on what the best cost benefit is for you. If you are to replace it install an external gutter.

Many Taylor can be remedied with overflows, riveting the gutter, tidying up corners, resetting the gable under flashings and installing stop ends.

Monitor afterwards.

Decisions made, repairs made, so now its time to monitor. The only good repair is a successful one. Have the walls dried out? Has decay stopped? How will you know unless you installed moisture probes and have them monitored.

Its all too easy for a contractor to tell you 'she'll be right' but that is the oldest saying in the book. This time you must know and must have proof. Probes don't lie.

Good planning. following processes, providing specifications and warranties have little bearing on what actually happens during heavy rain and as your building ages. Builders are liable for 10 years. But what are they liable for if they don't use the probes? You won't know one way or the other even with the warranty in your hand.

You got to this position because the building industry does not monitor itself. Your problem is the consequence. Ask yourself 'the Taylor system is so blatantly defective how the hell did it get accepted by builders in the first place'.

Same question should be asked about H1 and UTKD. They certainly have no place in external walls of homes. Give yourself a leg up and get the tools to monitor so you can prove to yourself that your walls are no longer getting wet by Taylor Fascia.

Otherwise next rain all you'll be thinking 'is it getting in again'.

Taylor Fascia does not comply with the building code

Never did, never will. Emphatic no.

The building regulations are based on performance codes. Weathertightness is based on External Moisture E2.3.2.

E2.3.2 Roofs and exterior walls shall prevent the penetration of water that could cause undue dampness, or damage to building elements.

The operative word is 'COULD'.

Compliance is meant to mean roofs and exterior walls shall be built so they could not leak.

Councils should have rejected building consents that included Taylor and Klass because they have at least 15 defects why they 'could' leak and drop water onto soffits and into walls to wet framing, insulation and cause decay, rust, mould loss of insulation, damage to GIB, flooring, skirtings and carpets.

This is another of the building industries big 'Oops' moments. No matter to them as after 10 years no-one can claim. Scott free so to speak.

Your problem to deal with this legacy. Added to this is framing that decays, underlay sagging, tiles leaking in wind driven rain, inadequate down pipes, inadequate valleys and gable under flashings. 

You are not alone. Industry claims Taylor and Klass has been installed on about 200,000 homes without any testing of any sort. Council does not want to talk about the Elephant in the room. Neither does BRANZ or the Government. Yet together they are the regulators and wrote the building code using the word  'could'

They have no interest in monitoring or Invasive testing as they know what trouble you will find. But you need to so you know what must be done.

Imagine if Taylor was Toyota, or Nissan, or Honda, or any reputable manufacturer. They would have recalled them and upgraded them into external gutters. 

If you are thinking of recladding this is one of the first products that goes into the skip bin. Not the only one I may add.

Document Taylor Fascia feeding Rainwater Tanks
Taylor Fascia feeding Rainwater Tanks.png
Taylor Fascia set up with Siphon System Feeding Water Tanks
This country home setting shows two large water tanks for collecting rain water feed from the roof via a Taylor Fascia gutter system.

The main house is behind the trees to the right about 50m away. It is a large home. Both homesteads are built on the same level which sets the Taylor Fascia about 450mm above the rim of the water tanks.

Over the years they have suffered from numerous floods through the ceiling down lights and dripping windows. Roofers have installed about 20 over flows and extra down pipes which have all helped but not prevented 'the big rains' from getting inside.

What is happening is during rain events the tanks begin to fill. The tank level rises. The down pipes feeding the tanks are fully water tight right to the Taylor Gutter. They have to be or precious rain water is lost. The down pipes have no relief against blockages or back pressure. When full the right tank top white pipe runs off to an underground overflow drain which is near level for 100m to discharge into a creek. The exit pipe would be 400mm below the Taylor Fascia.

This means the down pipes have a resting water level at 400mm below the Taylor Fascia. Heavy rain then fills the gutters which flow into the down pipes which are already fill to the 400mm mark. Gravity does not allow the same flow rate as a normal 2.7m fall storm water systems provide. Result is water level rises and overflows mostly out the 20 overflows.

The roofers nearly got success however they miscalculated the Taylor Fascia on the far side of the house, with the furthest to travel have roof valley flashings which have been cut-out in the back of the gutters to feed the valley flashing.

Lowering the overflows again will assist but even then the shear volume of water and its back pressure all the way from the creek to the Taylor Fascia will never be 100% safe. The restrictions on gravity and flow rate means it will still overflow in heavy rain.

When the Taylor gutter has debris, moss, leaves and dirt blocking flow it will cause even more overflows into the ceilings.

Taylor Fascia is not suitable for siphon system water storage systems. Always make sure you use external gutter systems as any overflow is safely dropped into gardens and lawns.

Many owners are thinking Green at the moment and water conservation with storage tanks. Think twice if your gutters are Taylor Fascia and if you must specify overflows and have the tanks sunk into the ground so gravity works in your favour.
