Refurbishment

Keep an eye on the condition of your roof at all times with Sita. Flat roof refurbishment is required more and more frequently. There are lots of reasons for this – changed regulations, leaking old rainwater outlets and pipelines, damaged roof skin and even saturated insulation. Statutory regulations mean that thermal insulation has to be topped up. As your refurbishment partner we can help you to update your drainage system — and comply with the required standards.
