Cleaning a Patio Cover
with a Telescopic Pole

Leaves, pollen, bird droppings and green deposits settle on every patio roof, whether glass or plastic. You cannot walk on most roofs. With a telescopic pole you clean the surface from the ground or from a ladder. Here you can read what you need for it, how to proceed step by step, what glass, multi-wall panels and aluminium can take and what happens to the sun protection under the roof.

The Short Answer

With a telescopic pole you clean the patio cover without scaffolding and without walking on the roof. Soft attachments, mild washing-up liquid and plenty of clear water are what matter. You will find further topics on pergolas and patio roofs in the pergola guide.

  • Push the sun protection under the roof together or take it down, and cover furniture and plants.
  • Sweep leaves and coarse dirt off dry with a soft broom on the telescopic pole.
  • Wash from top to bottom with lukewarm water, a little mild washing-up liquid and a soft brush.
  • Rinse thoroughly with clear water and squeegee the water off with a rubber-bladed squeegee.
  • Do not climb onto the roof, no abrasive cleaners, no pressure washer on plastic panels.
Equipment

What You Need for Cleaning

A telescopic pole alone cleans nothing yet. The attachments are what matter: they must be soft so that glass and plastic do not get scratched. Many poles have a thread or a click-system connection for interchangeable attachments.

Telescopic Pole

The pole should extend far enough for you to reach the middle of each roof bay from the edge. If you also want to work from the ground, measure the height and depth of the roof beforehand.

Soft Brush or Wiper

A brush with soft bristles or a wiper with a microfibre cover loosens the dirt without attacking the surface. Leave out hard bristles and scrubbers.

Water and Mild Washing-Up Liquid

A bucket of lukewarm water with a little mild washing-up liquid is enough for almost any dirt. A garden hose with a gentle spray helps with rinsing.

Squeegee with Rubber Blade

A squeegee on the pole pulls the water off glass and panels. That leaves fewer limescale marks and streaks.

Safe Ladder

You can often reach the gutter from the ground with a gutter attachment, otherwise from a stable ladder. It is best if a second person holds the ladder.

Instructions

Cleaning the Patio Roof with the Telescopic Pole

1

Protect the Shading

Push the awning, shade sail or rope tension awning together under the roof or take the fabric panels down. That way no dirty water drips onto the fabric.

2

Cover the Surroundings

Cover furniture, cushions and plants on the patio. Choose an overcast, windless day, then the water does not dry on too quickly.

3

Sweep Dry

Sweep leaves, twigs and coarse dirt off with a soft broom on the pole. That way dry dirt is removed before water smears it.

4

Soak and Wash

Wet the surface with lukewarm water and a little mild washing-up liquid. Work with the soft brush bay by bay, from the high side of the roof towards the gutter.

5

Rinse with Clear Water

Rinse thoroughly with clear water until no more foam is visible. Otherwise washing-up liquid residue dries on as a haze.

6

Squeegee and Check the Gutter

Squeegee the water off towards the gutter. Finally, check that the gutter is clear so that the water can run off.

Glass, Multi-Wall Panels, Aluminium - What Each Material Can Take

The roof of a patio cover usually consists of glass or plastic, the frame of aluminium or timber. Plastic panels are more sensitive than glass. If in doubt, the care instructions of the roof manufacturer apply.

MaterialHow to CleanWhat to Leave Out
GlassSoft brush, lukewarm water with mild washing-up liquid, rinse with clear water, squeegee off with a rubber bladeAbrasive cleaners, steel wool, hard bristles, working in strong sun
Multi-wall and twin-wall plastic panelsSoft brush or microfibre, mild washing-up liquid, rinse with a gentle water jetPressure washer, solvents, harsh cleaners, abrasive cleaners, hard attachments
Solid plastic panelsAs for multi-wall panels, wipe especially gently so that no scratches occurDry rubbing, abrasive sponges, solvents
Aluminium frameDamp cloth with mild washing-up liquid, wipe with clear waterAbrasive cleaners that attack the coating
Timber frameBrush off dry, wipe damp if needed and let dry wellPressure washer, standing water
Gutter and Conservatory

Roof Gutter and Conservatory with the Pole

The gutter catches the water from the whole roof. If it is blocked, the water overflows and leaves marks on the frame. A conservatory needs the same care from outside and additionally from inside.

Cleaning the Gutter with the Telescopic Pole

With a gutter attachment or a small scoop on the pole you get leaves out of the gutter. This can often be done from the ground. If the pole does not reach, work from a stable ladder. Afterwards rinse with the hose and check that the downpipe is clear.

In Spring and Autumn

A thorough clean is worthwhile in autumn, once the leaves have fallen, and in spring after the pollen. In between, it is enough to remove leaves and bird droppings.

Cleaning the Conservatory Roof

You clean the conservatory roof on the outside in just the same way as a patio roof. Here too: do not walk on it, soft attachments, mild washing-up liquid, plenty of clear water.

Cleaning the Conservatory from Inside

You can also clean a conservatory from inside with a telescopic pole. First push the shading all the way together. On a roof with a slope, the fabric bundle of the rope tension awning parks at the highest point, and a stopper on the first aluminium tube holds it there. That way you can reach the free bays with the pole.

Do Not Climb onto the Roof
Glass and plastic roofs are as a rule not walkable. Work from the ground or from a safe ladder, never on the roof.
No Pressure Washer on Plastic
The hard jet can attack the surface of multi-wall panels and force water into the chambers. A gentle jet from the garden hose is enough.
No Abrasive Cleaners or Solvents
Scouring cream, steel wool and harsh cleaners scratch plastic and can attack coatings. Mild washing-up liquid is enough.
Not in Strong Sun
On a hot roof the water dries on immediately and leaves streaks. Clean in the morning, in the evening or on an overcast day.
Sun Protection Under the Roof

And the Shading Under the Patio Roof?

Many patio roofs and pergolas carry a fabric sun protection underneath. The fabric has its own care rules. It is sun protection, not a storm or rain roof.

Park the Fabric Bundle Under the Roof

Pushed together, the fabric of the made-to-measure rope tension awning belongs under the roof, and the bundle must not lie exposed to the weather. While you clean the roof, it stays pushed together.

Clean the Fabric

The panels can be taken down and cleaned. How to do that depending on the fabric is explained under Cleaning an awning and, for sails, under Cleaning a shade sail.

Dry First, Then Hang

Only hang the panels again and push them together once the fabric is completely dry. Pushed together damp, mildew forms easily.

Made-to-Measure Pergola Sun Protection

For pergola sun protection and patio roofs we make the rope tension awning and the made-to-measure rope tension shade sail. Whether the protection is better above or below the roof is explained under Sun protection above or below the patio roof.

More on the Pergola

What makes a pergola, which roof types there are for the pergola and which ideas for the pergola roof are worthwhile are covered in their own articles. For a small space: Pergola on the balcony without drilling.

First push the sun protection under the roof together and cover the patio. Then sweep off leaves dry, wash with lukewarm water, mild washing-up liquid and a soft brush on the telescopic pole, rinse with clear water and squeegee the water off with a rubber blade. You do not walk on the roof while doing this.

Yes. With a soft brush or a microfibre wiper and a squeegee on the telescopic pole you clean a glass roof from the ground or from a ladder. Work on an overcast day, then fewer streaks remain.

With a soft brush, lukewarm water and mild washing-up liquid, then rinse with a gentle water jet. Pressure washers, solvents and abrasive cleaners attack the surface. This also applies to twin-wall panels.

Not on plastic panels, because the hard jet can damage the surface and force water into the chambers of the multi-wall panels. On glass, too, the garden hose is enough. If in doubt, the care instructions of the roof manufacturer apply.

Glass and plastic roofs are as a rule not walkable. So clean with a telescopic pole from the ground or from a secured ladder.

Thoroughly in spring and autumn. In between, remove leaves and bird droppings before they dry on or leave stains.

Push the awning or shade sail together beforehand or take the fabric panels down. That way no dirty water drips onto the fabric. Only hang and push together once the fabric is completely dry.

Push the interior shading all the way together, on a sloping roof to the highest point. Then clean the panes with a soft brush, mild washing-up liquid and a squeegee on the telescopic pole and rinse with clear water.
