Extension Ladders
Extension ladders give you safe reach for guttering, fascias, second-storey access and outside maintenance where a short ladder just will not do.
If you're working above single-storey height, a proper long ladder matters. These extension ladders are built for roofline jobs, external fixes and access work where stability and working length count. Choose a double extension ladder for straightforward reach, or a triple extension ladder when van space is tight but the job still needs height.
What Are Extension Ladders Used For?
- Reaching gutters, soffits and fascias on domestic jobs is where extension ladders earn their keep, giving roofline installers and maintenance teams the height they need without dragging full scaffold onto a quick repair.
- Accessing first and second-storey windows for cleaning, sealing or inspection is far easier with a long ladder that extends properly and gives you enough overlap between sections.
- Working on external lighting, CCTV, cabling and alarm gear suits a double extension ladder or triple extension ladder when sparkies need quick access up a wall and back down again.
- Handling decorating and repair work on outside walls, render and cladding is a common job for aluminium extension ladder models because they are easier to shift round the plot through the day.
- Getting onto low roofs, flat roofs and upper-level access points is another standard use, especially when the ladder is long enough to extend past the landing point for safer step-over.
Choosing the Right Extension Ladders
Sorting the right one is simple: buy for the working height you actually need, not the number printed on the side.
1. Double or Triple Section
If you are mainly doing straightforward domestic access and want fewer moving parts, a double extension ladder is usually the better shout. If van space is tight but you still need extra reach for second-storey work, a triple extension ladder folds shorter for transport and storage.
2. Material Matters
An aluminium extension ladder is the usual pick for general building, roofing and maintenance because it is lighter to carry round site. If you are working near electrical risks, stop and look at fibreglass ladders instead.
3. Closed Length vs Working Height
Do not just buy the longest ladder you can afford. If it is too long closed, it becomes a pain getting on the van and through side access. Check the stored length, extended length and realistic reach height so the ladder works both on the job and getting there.
4. Job Duration and Access Method
If it is a quick up-and-down task like inspection, cleaning or one fixing, extension ladders make sense. If you are working hands-free for longer periods, look at access towers and scaffold rather than forcing a ladder into a job it is not meant for.
Who Uses These on Site?
- Roofers and roofline installers use extension ladders for gutters, fascias, soffits and quick inspection work where they need proper reach without overcomplicating the setup.
- Sparkies rely on them for outside lights, CCTV, alarm boxes and cable runs, especially on domestic jobs where a triple extension ladder gives the height but still fits in the van.
- Decorators and maintenance teams use a long ladder for masonry repairs, exterior painting and snagging high-level defects that are awkward from a short step ladder.
- Window cleaners, surveyors and property repair teams keep an aluminium extension ladder handy because it is easier to move around the property for repeated up-and-down access.
- General builders and facilities crews often compare these with trade ladders when they need more reach for outside work than a standard site ladder can give.
The Basics: Understanding Extension Ladders
The important bit is not just how tall the ladder is. What matters is how it extends, how much overlap stays between sections, and whether it gives you safe access for the job in front of you.
1. Double vs Triple Extension
A double extension ladder uses two sections and is usually simpler and quicker to set up. A triple extension ladder uses three sections, so it stores shorter but still reaches higher, which helps if you need a long ladder that will still fit in or on the van.
2. Extended Length Is Not Your Working Height
You do not stand on the very top rungs, and you usually need the ladder to extend above the landing point if you are stepping onto a roof or platform. That means the usable working height is always less than the maximum extended length.
3. Angle and Contact Matter
Extension ladders work properly when set at the correct angle on firm ground with the stiles supported properly against the structure. Get that right and the ladder feels planted. Get it wrong and even a good ladder will feel sketchy.
Extension Ladder Accessories That Make the Job Safer
The right add-ons save time, stop damage and make repeated access work less of a faff.
1. Ladder Stand Offs
A stand off keeps the ladder clear of gutters and gives you a steadier position at the top. It is worth having when you are working around fascias, window reveals or awkward overhangs instead of crushing the very thing you are trying to fix.
2. Replacement Feet
Worn feet are one of those things lads ignore until the ladder starts slipping on smooth ground. Change them before they are shot and you avoid turning a decent ladder into a risky one.
3. Ladder Levellers and Stabilisers
If you are forever setting up on uneven paths, soft ground or rough drives, stabilising gear makes a big difference. It helps keep the base right instead of packing one side with whatever is lying about.
4. Storage and Transport Kit
Proper transport brackets and tie-down points stop damage in transit and keep the ladder from shifting on the roof rack. Have a look through ladder accessories if your current setup is chewing through kit.
Choose the Right Extension Ladders for the Job
Use this quick guide to match ladder type to the work in front of you.
| Your Job | Category or Type | Key Features |
|---|---|---|
| Guttering, fascias and first-storey outside repairs | Double extension ladder | Simpler setup, solid overlap between sections, good reach for standard domestic work |
| Second-storey access where van space is limited | Triple extension ladder | Higher reach from a shorter stored length, easier transport, suits mobile maintenance teams |
| Repeated external inspection and property maintenance | Aluminium extension ladder | Lighter to handle, easier to carry round the plot, practical for frequent repositioning |
| Quick access jobs in tight storage conditions | telescopic ladders | Compact storage, fast deployment, handy for van-based trades with limited room |
| Longer duration high-level work with both hands needed | Access platform instead of ladder | More stable working position, better for extended tasks, safer where repeated movement is needed |
Common Buying and Usage Mistakes
- Buying purely by overall length is a common mistake. What matters is safe working height and how much ladder must extend above the landing point, so always check the real reach for the job.
- Choosing a ladder that is too long when closed causes grief before you even start. If it is awkward on the van or will not get through access routes, it soon becomes dead weight instead of useful kit.
- Using extension ladders for long-duration work is the wrong call. They are for access and short tasks, so if the job keeps you up there for ages, move to a more suitable access setup.
- Ignoring worn feet, damaged rungs or bent stiles is asking for trouble. Check the ladder before use and replace parts or the ladder itself before small damage turns into a proper safety issue.
- Setting the ladder too steep or too shallow makes even a decent ladder feel unstable. Stick to the correct angle and firm footing rather than trying to make a bad setup work.
Double Extension Ladder vs Triple Extension Ladder vs Telescopic Ladder
Double Extension Ladder
This is the straightforward choice for plenty of domestic and site access work. Fewer sections means less faff, and they usually feel simpler to extend and close down. Best if you have the transport space and do not need the shortest stored length.
Triple Extension Ladder
A triple extension ladder is the better fit when you need serious reach from a ladder that still stores shorter. Good for van-based trades doing second-storey access, though there is more mechanism and setup to deal with than a two-section ladder.
Telescopic Ladder
Telescopic ladders win on storage and portability, especially for service engineers and snagging work. They are handy, but for regular high-reach outside work, many trades still prefer the feel and reach format of full extension ladders.
Maintenance and Care
Clean Off Grit and Plaster
Brush down the rungs and sliding sections after site use. Dust, plaster and grit in the moving parts make extension ladders rough to operate and can wear contact points faster than they should.
Check the Feet Properly
The feet take a hammering on drives, slabs and rough ground, so inspect them regularly for wear or hardening. If they are shot, replace them before grip becomes a problem.
Inspect Ropes, Locks and Guides
On ladders with operating ropes or locking catches, make sure everything runs cleanly and engages properly. If the sections do not lock as they should, do not chance it on the next job.
Store Them Dry and Supported
Do not leave your long ladder dumped where it can bow, get knocked about or sit in standing water. Store it flat or properly supported so the stiles stay straight and the moving sections keep lining up.
Replace Damaged Ladders Early
A bent stile or damaged rung is not something to work around. Minor wear can be sorted, but structural damage is the point where replacement is the sensible call.

Extension Ladders FAQs
What size ladder do I need for a 2 story house?
For most standard UK two-storey houses, you are usually looking at an extension ladder that gives enough reach for gutter line and eaves work without standing on the top rungs. The key is not just the ladder's full length, but its safe working height and whether it extends above the landing point if you need to step across.
How many sections does an extension ladder have?
Usually two or three. A double extension ladder has two sections and suits plenty of straightforward access jobs. A triple extension ladder has three sections, which helps you get more height from a shorter closed length, handy when transport space is tighter.
What is the safe working angle for an extension ladder?
The standard guide is around 75 degrees, often remembered as the one in four rule. That means for every four units up, the base comes one unit out. Set too steep and it feels ready to tip backwards. Too shallow and the feet are more likely to slip out.
Are aluminium extension ladders strong enough for regular trade use?
Yes, as long as you buy the right duty rating for proper site and trade work. Aluminium extension ladders are popular because they are lighter to move and still tough enough for repeated outside access jobs. Just do not confuse light domestic ladders with trade-rated kit.
When should I use something other than extension ladders?
If the job keeps you working at height for a long stretch, needs both hands free constantly, or involves a lot of side reach, a ladder is not the best answer. That is when a tower, platform or scaffold setup is the safer and more practical choice.
Can I use an extension ladder near electrical work?
Not if there is a live electrical risk and you are using aluminium. Metal ladders conduct, so for that sort of work you want a non-conductive option designed for the job. That is exactly where fibreglass models come into their own.
