Metal Roofs Risk Points:
- Side and end lap joints
- Sealants
- Fasteners and attachment strength
- Rain run-off and wind driven snow
- Penetrations for rooflights and apertures
- Perimeter trims
- Coatings and maintenance
Kingspan’s 30 years of experience in the metal roof systems demonstrates that KS1000 RW roof systems are reliable for roof slope applications of 4 degrees and above.
For roof slopes below 4 degrees, standing seam and low pitched solutions are essential as they have no exposed through fixings, preferably no end laps, incorporate barrel vault rooflights and include pre-engineered ridges, hips, eaves, valleys etc.
Kingspan roof systems are suitable for the following roof slope applications:-
Note: the finished roof slope takes all normal deflections into account.
To achieve the correct finished slope the steelwork will have to be designed with a greater fall, e.g. 2° to achieve a 1.5° finished slope. This is dependant upon span and to be checked with engineer.
*Dependant upon slate or tile specification

Design, Construction & Workmanship
The design and construction details shown in the roof and wall sections have been developed to provide robust and reliable weatherproof solutions using Kingspan’s range of insulated roof and wall systems.
Particular emphasis has been given to selecting sealant and fastener types co-ordinated with dimensions and positions which will be functional given a superior standard of on-site workmanship.
Surface Coatings
The range of surface coatings available on Kingspan’s insulated roof and wall systems are selected for their proven durability when exposed to the UK weather conditions.
Advice is available from our Technical Design Bureau for coating applications which are the most suitable for coastal or close to localised polluted locations.
