MGMA produces a range of guidance documents designed to educate specifiers and contractors alike on the type of metal gutter systems available, their application, superior life expectancy and unrivalled value over other material alternatives.
The roof drainage system is an important aspect of the overall roof design and the design process and the correct selection of materials can be complex. It is therefore recommended that in addition to reading the guidance documents, the designer consults an MGMA member for advice – details can be found in the members’ section of the web site.
All documents can be downloaded as PDF files by clicking on the document title.
Manufacturers are best placed to offer advice about their particular products and their published data should be closely adhered to; as any variation from their data during the design or construction process could result in the component or system failing prematurely or not complying with the guarantee or warranty conditions. Any uncertainty about the use or application of a product or system should be referred back to the manufacturer for detailed written advice.
