Absolutely. Safety is our primary concern—both for your property and our team. We assess every roof individually to determine its structural integrity before starting. Whether we use manual scraping, softwashing, or controlled pressure washing, we use techniques that protect your tiles and ensure the watertight seal of your home remains intact.

Not when performed by specialists. While aggressive, high-pressure “blasting” by an amateur can damage tiles, our precision pressure washing uses adjustable, professional-grade equipment. It is a highly effective and viable option for robust tile types or roofs with heavy carbon staining and compacted debris, providing an instant and thorough deep clean.

Softwashing is a low-pressure cleaning process that relies on HSE-approved, biodegradable solutions to kill organic growth. We favor this for the majority of Cardiff homes because it treats the root cause of moss and algae without mechanical force. It is the gentlest way to achieve a “like-new” finish on delicate or aged materials.

Most domestic projects in Cardiff are completed within one to two days. This includes property protection, moss removal, the cleaning treatment, and a full perimeter tidy-up. Larger commercial or industrial projects may take longer, and we provide a clear timeline with every quote.

No, as long as we have access to a water source and the perimeter of the building is clear, you don’t need to be present. We will keep you updated on our progress and perform a final walk-through or send photos once the job is complete.

No. Unlike a simple “water-only” wash, we apply a professional biocide treatment as part of our process. This penetrates the tiles to kill microscopic spores, significantly slowing down the regrowth cycle. Typically, a treated roof stays clean for 3 to 5 years depending on local tree cover.

Yes. We use eco-friendly, biodegradable biocides. As part of our “Property Protection” protocol, we pre-drench your grass and plants with fresh water, cover sensitive greenery, and rinse the area thoroughly afterward to ensure a safe environment for your family and pets.

Yes. Ace Roof Cleaning Cardiff and our subcontractors hold comprehensive Public Liability Insurance specifically rated for roof work and high-level cleaning. Our team is trained in the latest health and safety protocols and uses specialized access equipment to minimize risk.

Pricing depends on the size of the roof, the steepness (pitch), the type of tile, and the level of moss growth. We offer free, no-obligation site surveys and transparent quotes so you know exactly what the investment will be before we start.

We believe in the quality of our work, which is why we don’t ask for payment upfront. Once the job is completed to our high standards and yours, payment is due via bank transfer or card within 7 days of completion.
