Rainwater Calculations

With the ever-changing climates in the UK, many existing commercial and industrial buildings do not have adequate rainwater gutters and downpipes to effectively discharge of rainwater.

When over-cladding asbestos roof coverings these considerations are of paramount importance as the discharge from the new steel roof sheeting will be considerably faster.

Clad-IT have the latest Rainwater design software which has detailed algorithms to perform calculations to BSEN12056-3:2000.

By entering the detailed roof survey information which we will gather from your site appraisal, the building dimensions, geographical location, proposed gutter style and dimensions will be inputted into our software to ensure adequate drainage capacity will be achieved from the new roof refurbishment design.

All our rainwater calculation will be completed using rainfall data evaluated using Category 1 as defined in annex NB of BSEN12056-3:2000. This data relates to a storm return period of 1 year.

To achieve these results on existing commercial and industrial roof refurbishment projects, we look to use our experience and techniques to increase existing gutter girths using specialist gutter linings systems and add additional overflows and weir overflows where possible.
