Why regular conservatory roof cleaning matters
Your conservatory roof faces constant exposure to weather, pollution, moss growth, and stubborn dirt. Without regular cleaning, these elements can cause serious damage and reduce the lifespan of your roof panels.
Clean conservatory roofs offer:
- Maximum natural light transmission
- Prevention of structural issues
- Prevention of leaks and water ingress
- Better overall performance
Essential equipment for conservatory roof cleaning
Before starting the cleaning process, gather the right equipment:
Basic cleaning supplies include:
- Mild detergent (or specialised conservatory roof cleaner)
- Warm water/clean water for rinsing
- Soft brush or soft sponge
- Microfibre cloth for glass surfaces
- Spray bottle for cleaning solutions
- Garden hose for initial rinsing
For higher roofs:
- Telescopic brush (adjustable angle of the telescopic jet pipe)
- Roof ladder with proper safety equipment
Avoid using high pressure washers (as this can damage seals and cause more harm than good). It’s also a good idea to avoid harsh chemicals and abrasive brushes that can scratch glass.
Safety precautions: your first priority
Safety should always be your first step when cleaning any conservatory roof.
Check weather conditions and choose a good time with mild temperatures before attempting to clean your conservatory roof. Avoid overly hot, rainy or windy conditions. Inspect the roof for structural issues first before attempting to clean.
It’s also important to have someone nearby when working at height or on a ladder.

How to clean conservatory roof: step-by-step cleaning method
Step 1: Remove loose debris
Start by clearing loose dirt and debris from your conservatory roof. Use a soft brush or vacuum cleaner to remove leaves, twigs, and surface dirt. This prevents scratching during the wet cleaning phase.
Step 2: Prepare your cleaning solution
Mix warm soapy water using mild detergent. For stubborn stains, add white vinegar to your cleaning solutions. Avoid harsh chemicals that could damage special coating on glass panels or polycarbonate roofs.
Step 3: Initial rinse
Use a garden hose to rinse the roof. This removes additional loose debris and prepares the surface for cleaning. Avoid high pressure settings that might force water into seals.
Step 4: Apply cleaning solution
Using your spray bottle, apply the soapy water generously across affected areas. Allow the solution to sit for 10-15 minutes to break down stubborn dirt and atmospheric pollution.
Step 5: Scrub gently
Work systematically across your glass conservatory roof or polycarbonate panels using a soft brush or telescopic brush. Pay special attention to areas with moss growth or water spots.
Step 6: Rinse thoroughly
Rinse all surfaces with clean water, working from top to bottom. Ensure all cleaning solution is removed to prevent streaking on glass surfaces.
Step 7: Final polish
Use a microfibre cloth to dry glass roof panels and prevent water spots. This step is crucial for achieving the best results on your conservatory glass roof.
Cleaning different roof types
Glass conservatory roofs
Glass panels require gentle handling with soft cloths and appropriate cleaning solutions. Focus on achieving streak-free glass surfaces for maximum light transmission.
Polycarbonate roofs
These lightweight panels need careful cleaning to avoid scratching. Use warm soapy water and soft sponges, avoiding any abrasive materials.
Tiled conservatory roofs
Solid roof systems like SupaLite require different approaches, focusing on cleaning gutters and checking for moss growth around tiles.

Establishing a regular cleaning schedule
Create a regular cleaning schedule to maintain your own conservatory effectively. Plan a deep clean of all roof panels every quarter, whilst monthly maintenance should focus on clearing debris and checking for potential issues.
Schedule an annual inspection for professional assessment of wear and damage to catch problems early. The good news is that regular maintenance prevents costly repairs and keeps your conservatory in pristine condition.
When to call professional help
While DIY cleaning works well for routine maintenance, certain situations require professional intervention:
- Extensive moss growth requiring specialist treatment
- Structural issues or damaged roof panels
- Roofs too high for safe DIY access
- Persistent stubborn stains despite regular cleaning
- Special coating requiring professional products
Professional conservatory cleaning services have the expertise and equipment to handle challenging cleaning tasks safely.

How often should I clean my conservatory roof?
For best results, clean your conservatory roof every 3-4 months with monthly debris removal. Regular cleaning prevents stubborn stains and moss growth that can cause expensive repairs. However, if your conservatory faces trees or is in a particularly exposed area, you may need more frequent cleaning to maintain pristine condition.
Can I use a pressure washer to clean my conservatory roof?
Avoid using high pressure washers on conservatory roofs as the intense water pressure can damage seals, force water into joints, and crack glass panels or polycarbonate roofs. Instead, use a garden hose with moderate water pressure combined with warm soapy water and a soft brush for safe, effective cleaning without risking structural damage.
Signs your conservatory roof needs replacement
Sometimes cleaning isn’t enough to restore your conservatory roof’s performance.
Watch for warning signs including persistent leaks that continue despite thorough cleaning, cracked or damaged panels that compromise the roof’s integrity, and poor thermal performance that makes the space uncomfortable.
Excessive condensation inside your conservatory and any structural damage that affects safety are also clear indicators that replacement is necessary. A replacement conservatory roof, while an initial investment, can pay dividends as it prevents costly repairs down the line and helps to create a useable, thermally-efficient space. Replacing an old or failing conservatory roof with an insulated modern design can also significantly reduce heating bills.
