As a prospective new homeowner, you probably can't wait to have a 'roof over your head' for which you'll no longer have to pay rent at the end of every week.
Surf Coast is listed as a bushfire prone area. As such, you need to make deliberate efforts to minimize the fire risk associated with all structural components of your house. The roof is perhaps the best place to start. Here are a few ideas.
The truss is the triangular structure/framework onto which metal roofing panels are installed. The weight of the roof panels and anything that goes onto the panels (e.g. solar panels) is supported by the truss.
Roof trusses are either made of steel or they're made of wood. Trusses made of wood are more commonly used for residential construction than those made of steel. However, building in an area that's prone to bushfires doesn't allow you to settle for the common truss material.
Wood has a higher affinity for fire than metal. As such, a wooden truss will be a greater fire hazard on your roof than a truss made of steel. There's nothing wrong with settling for the unconventional truss material, especially when it's the safer alternative.
Metal Roof Insulation
The importance of proper insulation for metal roofing systems cannot be emphasized enough. You have several types of insulation to choose from for your metal roof. These include fiberglass batts, spray foam insulation and structural insulation panels (SIPs).
Structural insulation panels would be a wrong choice of insulation material for your metal roof. The standard SIP is made using two wooden structural boards and expanded polystyrene. Polystyrene is sandwiched between the two boards and it's highly flammable. Thus, settling for structural insulated panels would increase the fire hazard within your roofing system.
Spray foam or fiberglass insulation will be less of a fire hazard as compared to structural insulation panels. Between the two, Spray foam would be a better choice because fiberglass batts seldom create an air-tight roofing system.
Contrary to what many people believe, a metal roof doesn't attract lightning and it's not more vulnerable to a lightning strike than any other types of roof. If anything, a metal roof may make lightning strikes less dangerous.
However, consider the fact that lightning is known to have an affinity for the highest points of a structure. The fewer the high points on your metal roof, the less likely it is that lightning strikes will be a problem. For more information, contact companies like S.E.R.S. Sheetmetal & Roofing.Share
