How long it takes
Duration comes down to the size of the roof, the condition it is in and the system specified. A sound roof that needs cleaning, minor repairs and a coating finishes far quicker than one needing extensive cut edge corrosion treatment, gutter works or sheet repairs first. The survey is what tells us which situation applies, which is why we will not promise a timescale before we have seen the roof.
Weather is the other big factor. Coatings need a dry, clean substrate and conditions within the manufacturer's range, so wet or very cold spells can pause work between stages. We build realistic allowances into the programme rather than commit to dates we cannot hold, and we keep you posted if conditions force a change.
The stages always run in a fixed order: cleaning, repairs and prep, priming where specified, then the coating, with curing time between coats set by the manufacturer. Because the work happens at roof level, most projects cause little disruption inside, and trading usually carries on as normal.
