Membrane roofing solutions christchurch.jpeg

Roofing membrane installation requires specialised knowledge and techniques. Dwellsmiths have the expertise to identify and install the ideal roofing membrane system to suit your home or business. 

The appropriate membrane solution for your roof depends on your roofing structure and requirements. We complete a thorough assessment and inspection before recommending the best membrane solution for your roof.

Our team have experience working with many types of membrane options and have the expertise to advise and install the ideal solution for your home or commercial property.


Conventional Uninsulated 

Roof membrane is installed directly to the deck (usually wood or concrete), and is exposed to the weather. There is no insulation directly below the membrane. In a wood deck of this type the insulation, if used, is typically installed in the supporting joist space, which must be cross-vented. 


Conventional Insulated 

Roof membrane is installed directly over insulating materials, which are installed on the deck (wood, concrete or steel). The membrane is exposed to the weather. 


Protected (or Inverted) Membrane 

Roof membrane is installed directly to the deck (wood, concrete or overlaid steel). Extruded polystyrene is installed over the membrane covered by filter fabric and appropriate ballast. Ballast is required to counteract insulation flotation and wind uplift, and to provide ultraviolet resistance for the insulation. A modified protected membrane includes insulation both above and below the membrane. It is often used to provide slope to the membrane in order to improve drainage or to move the dew point away from the membrane.

MEMBRANE TYPES (Most common) 

Modified Bitumen

Generic description for pre-manufactured sheet membranes consisting of asphalt, modified with a polymer, which improves the physical properties of the asphalt and coated on a reinforcing mat or carrier.  Different polymers offer different physical properties.  Sheets may be installed either in hot asphalt or by heating with a propane torch, and in some cases they may be self-adhesive.  Applications normally consist of 2 plies but may be a single ply in certain well sloped applications.

EPDM (Ethylene Propylene Diene Monomer)

A generic description for synthetic rubber sheet membranes.  Applied only in single-ply applications on all roof types.  Seams are accomplished with proprietary adhesives.


PVC (Polyvinyl Chloride and TPO (Thermoplastic polyolefin)

Generic descriptions for a plastic sheet membrane. Applied in single-ply applications on all roof types.  Seams are accomplished by fusion either with solvent or hot-air welding techniques.


Although these are the most commonly used generic flexible membranes, there are other types on the market (each of which, as mentioned, requires special knowledge and techniques). 

  • What type of metal is suitable for an architectural roof?
    Various metals can be used, such as steel, aluminum, or copper. The choice depends on factors like durability, budget, and aesthetic preferences.
  • How does the design and colour of the metal roof contribute to the overall aesthetics of the building?
    The architectural design enhances the building's visual appeal. Features like profiles, textures, and colour options play a crucial role in achieving the desired look. We offer a wide range of colour and finish options, including matte, gloss, or textured finishes. These choices allow ultimate control over your home.
  • How durable is the chosen metal, and how does it withstand different weather conditions?
    Metals like steel and aluminium are known for their durability and resistance to elements. Proper coatings and treatments enhance weather resistance, ensuring longevity.
  • What maintenance is required for the metal roof, and how often should it be inspected?
    Regular inspections for debris, damage, or coatings are recommended. Maintenance typically involves cleaning and addressing any issues promptly.
  • Can you describe the installation process for the architectural metal roof?
    Installation involves preparing the roof substrate, applying underlayment, and then installing metal panels or shingles. Proper installation is crucial for optimal performance.
  • What is the estimated cost for installing the architectural metal roof?
    Costs vary based on metal type, design complexity, and project size. A detailed estimate includes materials, labor, and potential additional expenses.
  • How does the metal roof contribute to energy efficiency and insulation?
    Metal roofs can reflect sunlight, reducing heat absorption. Combined with proper insulation, this contributes to energy efficiency by maintaining interior temperatures.
  • How well does the metal roof resist elements like wind, hail, and heavy rain?
    Metal roofs have excellent resistance to wind, hail, and rain. The choice of metal gauge and profile influences their ability to withstand specific weather conditions.
  • What warranties are provided for the metal material and installation work?
    Warranties vary but often include a manufacturer's warranty for the metal and a separate warranty for the installation work. It's essential to review and understand the terms.
