Reasons to consider a new roof Failing roof water ingress unseen damage. Lack of insulation freezing pipes in winter overheating of services in hot summers loss of energy increasing carbon footprint. Failing roof which leaks allowing water ingress into the building fabric, causing unseen damage. Lack of insulation on existing roof, causing problems with freezing pipes in winter and overheating of services in hot summers. Loss of energy and increasing carbon footprint. 11/22/2018

Reasons to consider a new roof Health and Safety old asbestos and fibre cement roofs are fragile access onto roof carried out by trained operatives. Appearance poor impression to visitors retailers’ requirements Health and Safety – Old asbestos and fibre cement roofs are very fragile and any access onto the roof to work on service ductwork will have to be carefully carried out by trained operatives. Appearance – An old asbestos roof or failing metal roof can give a poor impression to visitors – many retailers have a policy of not using food manufacturers with asbestos roofs. 11/22/2018

What are the Options? Repair Over – Roof Replace the roof Or get some Umbrellas and Buckets 11/22/2018

Repair Roof over 25 years old think carefully about spending on repairs. corroded fixings sealant will have turned to dust in the laps rooflights will have lost their gel coating metal roof end laps will be corroded and may be past repair. health and safety – most falls from height are on maintenance – usually through a rooflight If your roof is over 25 years old think carefully about spending on repairs. The fixings will be corroded, the sealant will have turned to dust in the laps. Any rooflights will have lost their gel coating. Metal roof end laps will be corroded and may be past repair. Consider health and safety – most falls from height are on maintenance – usually through a rooflight 11/22/2018

What is an Over-roof To leave your existing roof covering in place and provide a new system over the top 11/22/2018

Advantages of the Over-roof Minimal disturbance to area below Quick Relatively low cost option Provides a 40 year lifespan new roof covering 11/22/2018

Asbestos roofs Asbestos roofs –10% white asbestos 50 years life expectancy (the newest models are 30 years old now) Become very fragile with age Remove the asbestos if at all possible – ever increasing costs of disposal Asbestos roofs – usually contain no more than 10% white asbestos mixed into the cement to provide strength to the product. Life expectancy is up to 50 years, last asbestos sheets were manufactured around 1980 that’s a W reg in car speak- so the newest models are 30 years old now. With age they become very fragile and brittle and repairs become increasingly difficult to carry out . We would recommend removing the asbestos if at all possible – due to ever increasing costs in disposing of asbestos related products 11/22/2018

Asbestos Roofs If removal is not an option, it can be over-roofed. Issues are greater than with a metal roof: Fragile roofs – preventing people and debris falling through Dealing with Asbestos cement fibre release However, if it is not an option to remove the asbestos cement the system can be over-roofed. The issues are greater than with a metal roof and considerations have to made to deal with: Fragile roofs – preventing people and debris falling through Dealing with Asbestos cement fibre release 11/22/2018

Dealing with Falls from Height Preferred option: Safety Nets tied from the underside usually difficult in a food factory environment Safety line option: safety lines and safety harness difficult to provide a safe solution Preferred option: If possible Safety Nets tied from the underside – usually difficult in a food factory environment due to insulated panel ceilings and services in voids. Safety line option: Using safety lines and safety harness – difficult to provide a safe solution – proving loadings on a person falling – and the length of steel line or harness lanyard could be greater than the fall. 11/22/2018

The Problem To develop a system that can be fitted at roof level. To develop a system that has minimal disturbance to operations in factory below To develop an economic system 11/22/2018

Our Solution Utilising easily available materials - steel mesh and a purposed designed installation rig. Working in conjunction with the HSE, we have developed and tested a system that can be fitted from roof level – which will prevent a fall from height.

The Over Roof System Phase 1 – fit safety mesh and ashbar 11/22/2018

The Over Roof System Phase 2 – Lay Insulation Quilt 11/22/2018

The Over Roof System Phase 3 - Lay new outer sheet 11/22/2018

Project Steel – 16, 000m² Existing metal roof – single skin, probably over 20 years old Fixings failing, sealant at laps and joints will have dried out. Corrosion of steel sheets at end laps No Insulation Values Over Roofing a Metal Building Much easier to deal with - roof should be non fragile Any rooflights will have to be considered non fragile and usually protection can be undertaken by strip nets below or mesh from above 11/22/2018

Over Roof Guidelines Building Regs - U value 0.18 W/k Tata (Corus) HPS Ultra provides 25 year no quibble product guarantee Rooflights – difficult to get new roof in line when going over asbestos cement – 1016mm cover width v 1000mm on new roof New rooflights will have to be triple skin to conform to Building Regulations 11/22/2018

New Roofs for Old Remove your old roof and fit a new roof The best solution but more costly, longer programme period. More disturbance to production below Needs constant day to day planning with client to ensure on site movements do not interfere with clients. Internal appearance brand new – can be food safe. Costs for disposal of asbestos are continuing to rise 11/22/2018
