Keystone Roofing Ltd. brings 17 years of roof cleaning expertise to Cork. Our team uses soft wash systems and eco-friendly solutions to safely remove moss, algae, and lichen without damaging your tiles. We’re fully insured and registered, with every technician trained in safe roof access methods. Cork’s damp climate accelerates moss growth, which is why we recommend professional cleaning every 2-3 years to prevent costly water damage and extend your roof’s lifespan.
We begin with a complete roof inspection to assess moss coverage, tile condition, and structural integrity. Our soft wash system applies biodegradable biocides at low pressure, killing moss and algae at the root while protecting your tiles. After treatment, we clear all gutters and fascia boards to ensure proper drainage throughout your property.
Our assessment starts with a visual inspection from ground level to identify moss, algae, and debris buildup. We then conduct a close examination of your tiles, flashing, and valleys to spot potential leaks or structural issues. Using detailed photos and measurements, we document problem areas and determine the most effective cleaning method for your specific roof type. You’ll receive a clear, itemised quote with no hidden fees before any work begins. Our 17 years serving Cork properties means we spot issues that inexperienced cleaners miss.
Safety is our priority on every Cork roof cleaning project. We follow strict protocols to protect your property and our crew throughout the entire service. Our team arrives with professional-grade safety equipment, scaffolding access systems, and protective coverings for your landscaping.
We start with a practical assessment, explain the condition of the roof, and agree the right scope before work begins. You get updates during the job, daily site care where needed, and a final review before handover.
Timing depends on access, weather, materials, and the scale of the work, but our team keeps the process straightforward from first call to completion.

Ask About Roof CleaningWe recommend reapplying moss and algae treatments every 2-3 years, but you'll want more frequent treatments in heavily shaded areas. We'll help assess your roof's specific needs during our inspection.
We don't recommend cleaning roofs during rainy weather as it's unsafe and ineffective. Rain affects cleaning solutions and creates slippery conditions. For best results and safety, we'll schedule your cleaning during dry weather.
We don't recommend pressure washing as it can severely damage your roof tiles. It may strip away protective coatings, force water under tiles, and reduce your roof's lifespan. Let's use gentler cleaning methods.
Yes, we use environmentally safe cleaning solutions that effectively remove dirt and algae without harming your roof or the ecosystem. Our eco-friendly products are biodegradable and won't affect your garden or water supply.
