Northern Territory Capability Statement


Tired, damaged or aged roofing can quickly become detrimental to your home. A damaged roof is susceptible to adverse weather, which can impact wall-cladding, trusses and even your home’s electrical wiring.

Our team of roofing specialists have the knowledge and experience to replace, repair and upgrade roofing for the Northern Territory’s specific conditions.

Making your home safer, better looking and more valuable.


High quality wall-cladding is essential to ensuring your home’s safety and longevity from the elements.

Darwin’s harsh weather can often take a toll on external cladding. As your home ages, this can show signs of deterioration.

SEM Group can design, supply and install various styles of wall-cladding based on your preferences and requirements.

Wagaman Terrace

“SEM have just completed significant works at my home in the last couple of weeks. Here’s how it went. New roof to replace our old problematic leaking roof. Took about 4 days, and looks great. Was done safely also. Then came the solar and Tesla battery. Super efficient, clean and just professional the way it was installed and how we were shown to operate the system. 10/10. Wall-cladding replacement next. The boys did a great job and the transformation of the house is significant. Billy, Nick and Thi were there for very long days and the result was outstanding. Managed by the very communicative Minh, the whole process took about 3 weeks, and we are extremely happy with the result.”
