Tigerflex Shiplap Apex Shed – Show Site Review

Why this review matters (and why this one is different)

This review is of the TigerFlex Shiplap Apex Shed, and it’s important to say right from the outset that this is the most important TigerFlex review we’ve done.

Unlike several other TigerFlex variants where we’ve relied on modular familiarity and comparative inspection, we have physically inspected this exact shed — and not just once. We’ve inspected it at both the Tong and Otley show sites, across different visits, in different weather conditions, and after prolonged public use.

This is the shed that genuinely changed our opinion of the TigerFlex system.

And that context matters.

Our early scepticism of TigerFlex (and why it existed)

If you’ve read our earlier reviews, you’ll know that our first exposure to TigerFlex wasn’t through sheds at all, but through Tiger’s 19mm TigerFlex summer house log cabins.

At the time, we had mixed feelings.

Not because the materials were poor — they weren’t — but because the internal bracing and modular construction in those cabins took up more internal space than we were comfortable with. For a summer house or log cabin, internal space efficiency matters enormously, and the modular approach felt slightly at odds with that goal.

So when we came to the TigerFlex shed range, we’ll be honest:
we carried a bit of prejudice with us.

That prejudice didn’t last long.

How the TigerFlex shed range won us over

As we inspected more TigerFlex products — garden storage sheds, bike sheds, security sheds, pent sheds, and apex sheds — something became very clear:

👉 TigerFlex works exceptionally well for sheds.

The very things that felt intrusive in a cabin context — modular joins, reinforced frames, structural stitching — become major advantages in a shed.

The TigerFlex Shiplap Apex Shed is the clearest example of that.

The model we inspected: a classic, flexible apex shed

The shed we’re reviewing here is the windowed TigerFlex Shiplap Apex Shed.

Within the TigerFlex apex lineup, there are three main variants:

• A non-windowed version
• A security version (with enhanced security features and smaller windows)
• This standard windowed version, which we’re reviewing here

The design itself is a classic apex shed — but what elevates it is the modular execution.

Window layout and flexibility

This shed uses four windowed panels, each fitted with toughened glass. Because of the modular design:

• You can place windows on either side of the door
• You can run windows down one side
• You can balance light symmetrically
• You can adapt the layout to your garden, not the other way around

This is not common in traditional sheds, where door and window placement is usually fixed.

Understanding the modular layout (without the jargon)

The shed we inspected is built from multiple modular panels — effectively two modules deep and wider across the front, with:

• Solid panels
• Windowed panels
• A door module

The important takeaway isn’t the exact module count — it’s what that enables.

Because every panel is interchangeable, you can:

• Move the door
• Move the windows
• Optimise access
• Nestle the shed into a corner or alcove
• Work around paths, fences, or boundaries

This is where TigerFlex genuinely differentiates itself from almost every traditional shed on the market.

Offset door placement: a subtle but powerful advantage

One of the most underrated features of this shed is the offset door.

Because the door isn’t centred:

• You can position the shed closer to boundaries
• You can create uninterrupted internal wall runs
• You gain more usable internal layout options

In real gardens — which are rarely perfect rectangles — this flexibility can be the difference between a shed that just fitsand one that fits properly.

Build quality: setting concerns aside

If you come to this shed with concerns about modular construction, we’d encourage you to set them aside.

Everything about the build quality of the TigerFlex Shiplap Apex Shed is on par with Tiger’s non-modular sheds — and in several areas, better.

Let’s go through it properly.

Roof construction: doing it right

• 12mm tongue-and-groove roof boards
• No OSB
• Proper framing
• Strong fixing points

OSB roofs are still common in the market, and frankly, they’re not ideal if longevity matters. Once OSB takes on moisture, it degrades quickly.

This roof doesn’t do that.

The way the roof ties into the modular walls also creates a box-like structural effect, reinforcing the entire building. There’s no sense of the roof being a weak or separate element — it actively strengthens the shed.

Wall cladding: quality you can feel

The walls use 12mm shiplap tongue-and-groove cladding, and the quality here is immediately obvious.

On the outside:

• Smooth, clean finish
• No rough milling
• No protruding nails
• No splinter risk

On the inside:

• Smooth-planed framing
• Clean joins
• No sharp edges
• A genuinely premium feel

We ran our hands along the timber inside and out without hesitation — something we would not do in many cheaper sheds.

A real-world moisture test (without meaning to)

When we inspected this shed, it had:

• Been on site for around 12 months
• Experienced heavy foot traffic
• Been opened and closed constantly
• Just come through a stormy, damp period

Inside, it was:

• Bone dry
• No water ingress
• No musty smell
• Just the scent of fresh-cut timber

That alone tells you a lot about build integrity.

Floor performance: measured, not guessed

The floor deserves special mention.

• 12mm tongue-and-groove floor boards
• Bearers spaced very closely (roughly around a foot apart)
• Each board double-nailed into each bearer

We tested this floor with a 75kg load and measured deflection using a laser.

👉 Result: ~2mm of deflection

That’s excellent.

Double-nailing matters here. It means:

• No single point of failure
• Nails can’t work loose easily
• Long-term stability is vastly improved

This is not a “good enough” floor — it’s a properly engineered one.

Modular joins: strength through doubling

One of the clever side effects of TigerFlex’s modular design is that where panels join, framing thickness effectively doubles.

That means:

• Thicker frame sections at stress points
• Greater rigidity
• Less movement over time

We tested wall movement by applying a 75kg load against the wall and measuring with a laser.

👉 Result: ~3mm of deflection

For context, we’ve seen more movement in 28mm log cabins than in this shed.

That surprised us — and it speaks volumes.

Roof-to-wall integration: no weak links

Another area where cheaper sheds often fail is in how the roof ties into the walls.

Here:

• There’s no skimping on framing
• No reliance on minimal fixings
• No sense of “floating” roof panels

The whole structure behaves as a single, reinforced unit — almost like a box bridge.

That’s exactly what you want for longevity.

Windows: solid, not token

The windows here are:

• Proper toughened glass
• Well-framed
• Securely seated

They are not:

• Styrene
• Plastic
• Vacuum-formed inserts

Styrene windows yellow over time. Cheap plastic windows can flex or pop out.

These don’t.

One fair criticism (and a suggested upgrade)

To be completely honest, there is one area we’re less enthusiastic about — and we’ve mentioned this in other TigerFlex reviews.

• You need to supply your own silicone sealant
• You apply it yourself
• The window is then tacked in with nails

Even though it’s toughened glass, hammering nails near glass isn’t something everyone feels comfortable doing.

Tiger does offer a window upgrade kit with additional beading, and we’d strongly recommend considering it. It adds:

• A more finished look
• Greater confidence
• A more “premium” feel overall

Doors, locks, and usability

The door on this shed is:

• Well-framed
• Properly hung
• Solid in use

It comes with:

• A good-quality lock
• A proper door pull
• No rattling
• No flex

Everything works as it should — and continues to work after heavy public use.

Longevity under real wear and tear

Perhaps the most telling thing about this shed is that it has been heavily used.

Hundreds — if not thousands — of people have:

• Walked in and out
• Slammed the door
• Leaned on the walls
• Dragged feet across the floor

And yet:

• No sag
• No looseness
• No visible degradation
• No structural fatigue

That’s a real-world test most sheds never get.

Who this shed is really for

The TigerFlex Shiplap Apex Shed is ideal if:

• You want a traditional apex look
• You value flexibility of layout
• Your garden isn’t a perfect rectangle
• You want measured, proven solidity
• You care about long-term quality, not just specs

If you want something rigidly traditional with fixed layouts, there are simpler sheds.

But if you want a shed that adapts to you, not the other way around, this is a standout option.

Final verdict: the shed that sold us on TigerFlex

This shed is the reason we now speak so positively about the TigerFlex system.

It takes:

• Modular construction
• High-grade materials
• Excellent attention to detail

…and applies them in a context where they genuinely add value.

If you’re looking for a traditional apex shed, but you also want flexibility, strength, and longevity, the TigerFlex Shiplap Apex Shed is absolutely worth serious consideration.

It’s not just good on paper.
It’s good in the real world — and we’ve seen that first-hand.
