 Industrial Roofing 

Replace. Overclad. Clean.


Refurbishments can be a hassle. At SIAD, we understand that! We focus on beautifully renovating and rejuvenating your space all while striving to minimise interruptions to your daily routine.

Roof Replacement

Many industrial roofs require substantial renovations during their lifetime. Traditionally, old industrial buildings were clad with asbestos cement sheeting and these present a special maintenance problem. The sheets are fragile and often crack and leak. 


Once a roof has deteriorated to this point replacement is often the only viable option. SIAD have the experience, expertise and certification to make sure your old asbestos roof is safely removed and correctly disposed of according to regulatory requirements. 

Overcladding Existing Roofs

Disruption to your everyday operations can be a concern when considering roof replacement. However, if the roof is structurally sound, rather than replacement, there is a successful hassle free alternative method called overcladding.

Overcladding is the renovation of an existing roof by applying a ‘second skin’ over the top using metal sheeting. This process ensures your existing roof is fully covered against water ingress and your building remains weather proof.

Roof Cleaning

With age, the surface of an asbestos roof can discolour and become covered in moss and algae. This can cause problems and have a severe effect on the roof. It is possible to refurbish an asbestos roof to a high standard, using methods such as remote cleaning


Cleaning roofing will dramatically reduce the deteriorating process of any roof, by removing all the moss and neutralising root growth.


All works performed by SIAD are carried out strictly to CDM regulations and HSE guidelines.
