What is EPDM Rubber Roofing?
EPDM (Ethylene Propylene Diene Monomer) rubber is a durable and weather-resistant roofing material commonly used on flat and low-slope roofs. It is highly resistant to UV rays, ozone, and extreme weather conditions, making it a popular choice for commercial and industrial buildings.
Where is EPDM Roofing Used?
EPDM rubber roofing is found on various types of buildings, including:
• Data Centres – Protecting critical infrastructure with a watertight, durable surface.
• Warehouses – Providing long-lasting and cost-effective roofing solutions.
• Office Buildings – Ensuring efficient insulation and weather protection.
• Hospitals & Schools – Used for its low-maintenance and long lifespan.
• Retail & Commercial Properties – Ideal for large flat roofs requiring minimal upkeep.
• Residential Homes & Extensions – Common for flat-roofed extensions and garages.
How to Properly Clean EPDM Rubber Roofing
Maintaining an EPDM roof is crucial to extending its lifespan and preventing damage. Regular cleaning removes dirt, moss, algae, and other contaminants that can degrade the material over time.
Step-by-Step Guide to Cleaning EPDM Rubber
1. Remove Debris – Use a soft-bristle broom or a leaf blower to clear away leaves, branches, and dirt.
2. Prepare a Cleaning Solution – Mix warm water with a non-abrasive, pH-neutral cleaner or a dedicated EPDM roof cleaner. Avoid harsh chemicals, solvents, and petroleum-based products.
3. Apply the Cleaner – LBC Use a high volume low pressure sprayer to apply the cleaning solution evenly to a wide area in a controlled mannor.
4. Gently Scrub the Surface – Work in small sections using a soft brush to agitate the surface dirt.
5. Rinse with Clean Water – Use a pressure washer to rinse away residue.
6. Inspect for Damage – Look for any tears, punctures, or loose seams and repair them if needed.
Top 10 Questions About Cleaning EPDM Rubber Roofing
1. What is the best cleaner for EPDM rubber roofs?
The best cleaner is a pH-neutral, non-abrasive cleaner such as a mild dish soap or a dedicated EPDM roof cleaner. Avoid harsh chemicals like bleach or petroleum-based products, as they can degrade the rubber.
2. Can you pressure wash an EPDM rubber roof?
Yes, experienced professionals can pressure wash the roof using the correct techniques and nozzles and an adequately low pressure.
3. How often should you clean an EPDM roof?
It is recommended to clean an EPDM roof at least once or twice a year, preferably in the spring and autumn, to remove dirt and prevent algae or moss buildup.
4. How do you remove mold and algae from EPDM rubber roofing?
Use a mild detergent mixed with water or a dedicated EPDM-safe algae and mold remover. Apply it to affected areas, scrub gently, and rinse with clean water.
5. Can I walk on an EPDM rubber roof while cleaning?
Yes, EPDM is durable enough to walk on, but it’s best to wear soft-soled shoes and avoid sharp objects that could puncture the surface.

• Avoid standing water by ensuring proper drainage.
• Apply a protective sealant (if recommended by the manufacturer).
