The Fastnet System for Roof Protection
- to prevent wind storm damage.
Commercial Applications
Many roofs to commercial buildings are clad either in tiles or man-made slates which have been designed to wind loadings that do not meet modern day design requirements. The wind loading and the consequent recommended fixing methods could be underestimated by as much as 50%. As a result many commercial buildings have suffered, or are likely to suffer, roof damage by wind storms .
The installation of the Fastnet System for Roof Protection on these types of roof cladding will permanently prevent wind storm damage occurring. Examples of the installation of the Fastnet System on these types of roofs to commercial buildings are as follows:
Case History 1 - 1995
Type of Building
A Tesco supermarket situated in an exposed position overlooking the River Dee. The roof cladding comprised man-made slate tiles with pitched roof construction.
Reasons for Installation of the Fastnet System
Within two years of completion of construction of the supermarket building roof areas suffered wind storm damage resulting in slates being stripped from the roof and blown off the building. In addition to damage to the roof this also presented a clear danger to pedestrians and shoppers. Exercising due care Tesco commissioned the installation of the Fastnet System on the areas of roof vulnerable to this wind storm damage to ensure that these areas were permanently protected.
Installation
Paranet was installed on the roof areas requiring protection in accordance with the Fastnet System specification.
Results and Observations
The installation of the Fastnet System prevented any further damage to the protected areas and proves that the system is equally effective in protecting man-made slate cladding.
Case History 2 - 1997/1998
Type of Building
A Benefits Agency office building situated about three miles South-West of Glasgow city centre and of recent construction. The roof cladding comprised man-made slates with pitched roof construction.
Reasons for Installation of The Fastnet System
Sections of the roof suffered serious wind storm damage in early 1997 which was subsequently repaired. However further wind storms caused further displacement of slates, some of which fell into the staff car park causing serious concern due to the real possibility of human injury and damage to parked cars.
B.A. Estates (Scotland), exercising due care, commissioned the installation of the Fastnet System to the areas of roof prone to damage and this was completed in November 1997.
At the end of December 1997 further severe wind storms were experienced in the Glasgow area. The roof areas secured previously by the Fastnet System remained intact but other areas of unprotected roof were severely damaged, stripping slates and depositing them in the car park, again causing serious concern to all involved.
As a result of this further damage and the continuing threat of damage and injury to people and vehicles, B.A. Estates (Scotland) commissioned the installation of the Fastnet System on the whole of the remaining high level roof.
Installation
Installation of the Fastnet System to the whole of the complex high level roof areas was completed, the total roof area measuring some 1650 sq.m.. Installation also involved successfully fitting the Paranet in valley and hip areas.
Results and Observations
The project illustrates that the Fastnet System for Roof Protection can be simply and effectively installed on large and complex roof structures. Disturbance to the staff working in the building during installation was said to be minimal.
Even though the Paranet has been installed on large areas of roof it remains virtually undectectable to the human eye at ground level.
Installation of the Fastnet System has proved a permanent solution to serious wind storm damage which conventional methods such as replacing the cladding had failed to solve.
