Advantages of Different Roofing Systems

Historically, code requirements for roof systems have focused on life-safety concerns. However, additional provisions have been added to the International Building Code to cover many roofing issues, including reroofing projects. While life-safety concerns remain the main focus of code requirements, many other aspects are now included, including general serviceability.

There are several different types of insulation for roofing Adelaide. Foam-type insulation is an option for flat roofs. One type of foam has a high R-value: polyurethane sprayed-on foam. A 1-component spray polyurethane foam is commonly used on commercial flat roofing. Another option is insulated metal panels. These are often used in cold storage buildings. Both types of insulation are effective for retaining heat. Visit oldportroofing.com.au for more information.

There are a few different types of roof insulation. For example, those installed on joists can either use a sheet-material air barrier or a low-permeable foam insulation board. In either case, workers should wear eye protection and protective clothing. They should also follow basic hygiene principles. After the roofing material has been installed, the insulation is applied to the roof. Once this is done, the roof can be covered.


A roof coated with a coating will be more durable and resistant to the elements than a standard roof. Roofing coatings contain special chemicals that reduce heat penetration. Some of them are waterborne. Waterborne coatings may not be applied in rainy weather. They will create a chemical bond with the roof substrate during drying. A catalyst in the coating helps force trapped air to the surface. It is important because trapped air can cause future cracks.

Using a roof coating is a great way to restore the integrity of a deteriorated roof. A tough rubberised coating makes a foam roof more resistant to storm damage. Coatings for roofing can also protect the granules common on asphalt shingles, increasing UV protection and adding beauty to a home. Some coatings can also prevent the shingles from sticking together when packaged. These coatings are a cost-effective way to protect your home’s roof.

Fire resistance

A fire-resistant roof protects against the spread of fire and helps maintain the structure’s integrity underneath. The entire roofing Adelaide system must be fire-resistant, including the deck, insulation, underlayment, and roof slope. In addition, the sheathing material plays an important role in the fire resistance of a roof, preventing the spread of fire and minimising damage. Slate tile, for example, is an excellent choice for this purpose. Slate is non-combustible, but it is also heavy and requires specialised knowledge to install properly.


In general, the durability of roofing systems is determined by the thermal load at the exposure site, significant design and workmanship defects, and the selected generic roofing system. The table below shows how to calculate the mean and adjusted durability of seventeen different low and steep-slope roofing systems. It provides thermal loads for many different locations and roofing systems. However, there are some important details to keep in mind. Read on to learn more about roofing durability and how to increase the life of your roof.

Generally, the life expectancy of roofing Adelaide materials varies widely. For example, a flat roof may last 15 to 20 years, while an asphalt or cedar shingle roof may last for twenty or thirty years. Slate and metal roofing have a 50-year lifespan, although their cost will depend on your area. While most roofing materials require maintenance to stay in good condition, you may not need to replace the entire roof if there is a leak. Sometimes, the roof’s leaking could be a simple fix, like repairing a leak in the flashing. Visit oldportroofing.com.au for more information.


Many factors determine the overall cost of roofing. Depending on the type of material you choose, your roof will cost anywhere from $4,000 to $10,000. The type of framing and materials you choose will also affect the cost. The more expensive materials and labour, such as metal, you use on your roof, the more you will spend. In addition, some materials can be more difficult to install, such as wood shingles. If you choose this option, you should expect a cost of $500 to $750 per 100 square feet.
