Case Studies
Our case studies provide a more detailed account of some of the different projects that we have worked on. You can also read some of our customers' feedback here
Our team regularly carry out commercial roof cleaning projects which require a health and safety assessment regarding risks associated with working at height. A recent project involved cleaning both the roof and gutters of a large unit located in a retail park in Devon.
The corrugated low-pitch roof of the unit was surrounded by wide trough gutters. The roof had become discoloured due to organic growth including lichen which had started to develop on the roof, whilst the gutters had become blocked by luxuriant plant growth!
Dirt, in this instance washed down from the low pitch roof, and debris such as leaves, accumulate and decompose in gutters creating an environment that is surprisingly favourable to plant growth. Then, seeds carried by the wind and birds, land, take root and grow.
When gutters become so blocked water drains very slowly resulting in the gutters flooding. This can lead to water sitting above the roofline and leaking into the property causing immediate and long-term damage. It also dramatically increases the weight being held within the gutters which can also cause long-term issues to their structure.
The first task was to clear the gutters before we could start to clean the roof. Once these were clear water could once again flow freely down away from the roof and the building. We then worked on the roof removing lichen and other organic matter to leave it looking sparkling clean (see pics below).
As can often be the case, the cleaning element of this project was pretty straightforward. It was rather the proper management of health and safety with regards to high-level access and working at height that required our knowledge and experience.
Working on roofs is logically hazardous because it involves working at height. Roof work accounts for a quarter of all deaths in the construction industry - and not all people killed are roofers, many are maintenance workers such as ourselves.
OneFifty takes Health and Safety extremely seriously and we are rigorous about following the latest HSE guidelines. Our qualified operatives are experienced in working at height and our work is all fully insured.
On this project we used a fall arrest system for additional security. The purpose of a fall arrest system is to protect a person if they fall by shortening the distance of the fall and preventing them from hitting the ground. It includes three key components; i.) a body harness and ii.) a connector which is securely fastened to iii.) a reliable anchor point.
All anchor points require an annual inspection and must have the ‘pass’ test date clearly displayed. On this project we used pre-installed anchor lines that been inspected and approved as safe to use.
