Due to the increased use of insulation, more energy-efficient windows and doors, as well as house wraps, today’s homes have become more airtight than in the past. Consequently, these homes do not breathe as easily as before, which makes roof ventilation systems more important than ever.

During the hot season, the heat from the sun builds in the attic and radiates into the living space, which makes your home uncomfortable. That’s why air conditioning usage increases and roof shingles start to deteriorate. During the cold season, the moisture generated inside your home rises to the attic where it condenses and causes mould and mildew.

Lack of attic and roof ventilation system is one of the main contributors to winter ice dams that caused damage to many roofs and forced homeowners to consider roof replacement in Sydney.

While a ventilation system is beneficial to your roofing in Sydney, not every roof ventilator system, however, is favourable for homes. This calls for a careful inspection before installation. To help you know whether the attic and roof ventilation system is for you, we have compiled its pros and cons in this article.

Pro #1: Moisture control

Moisture is drawn to cold surfaces the same way it is drawn to your windows. When cold surfaces get wet, they start to rot and mould forms. The rot affects the framing and the roof decking, resulting in a sagging roof.

Moreover, sagging roofs leak and worsen the moisture problem in the attic, creating big problems in the living areas below. With a ventilation system in your roofing in Sydney, moisture has a place to escape before moulds and mildews appear and create further damage.

Con #1: Carbon Monoxide Risk

If you have natural gas or propane burning appliances (e.g. a furnace or water heaters), an attic ventilation system could lead to carbon monoxide poisoning. It could also create negative air pressure in your home’s interior. But if you want to install a ventilation system, you can try solar-powered or turbine attic fans.

Pro #2: Temperature Control

During the coldest season of the year, attic ventilation is necessary to maintain warmer room temperature. Interestingly, in the hottest season of the year, attic ventilation is just as important for the opposite reason—to keep the attic space cool. So, an attic ventilation system helps regulate the overall temperature levels within the house.

Con #2: Roof Leak Risk

According to experts, most types of attic ventilation systems are not designed to prevent water intrusion during hurricanes. They are only intended to keep out “normal” rainfall, which means the power of the wind can push water up the roof in sheets when rainstorms take place.

Furthermore, when do not install these types of ventilations properly, the probability of calling in the help of roof leaking specialists increases.

Pro #3: Reduced Energy Costs

Proper roof ventilation removes hot air from houses through the process called air circulation. The system minimises the workload on your air conditioner, therefore reducing your electric bill. Besides, the reduced temperature in the attic benefits the air conditioner by keeping the internal air and ductwork cooler.

Con #3: Not Always Energy Efficient

When attics are poorly sealed, it can lead to fans pulling conditioned air from inside the home into the attic. This makes your air conditioning unit work harder and still be counterproductive.

Even with a perfectly tight ceiling, powered attic ventilators use more energy than they save. For this reason, the production of solar-powered attic ventilators (supposedly off the grid) has begun.

Pro #4: Extended Roof Life

When the heat from inside your attic combines with the heat from the sun, ice damming happens. This occurrence leads to damaging your entire roofing system, your attic, and even inside the walls of your home. When this happens, you will be required to have roof replacement in Sydney.

When your attic heats up, the underlayment warms up as well. Over time, they will become brittle and ineffective. This is when proper roof ventilation system can prove to be a boon as it helps escape the warm air before it melts the snow and ice on your roof. The system does not let your roofing in Sydney turn brittle, therefore extending its life. Plus, you will be able to avoid the costly roof repairs in Sydney.

Conclusion

The cost of roof repair and roof replacements in Sydney can vary dramatically. Asking how much exactly will you be paying for these requires an answer with thorough research.

There are so many variables that come into play when talking about the cost of repairing, patching, or replacing a roof. Every house is different. So, each comes with a unique roofing problem that needs a specialised solution.

But to help you understand everything, we have put together in this article the common costs of roof repairs in Sydney as well as the factors that affect the costs.

Current Cost of Roof Repairs and Replacements

For roof repairs, roof leaking specialists generally charge from around $40 to up to $90 per hour. However, you should keep in mind that an hourly rate is not the best indicator of the total cost of a roof repair. A square metre rate can be more accurate, which price can vary depending on different factors.

For roof replacements, the general costs for a three-bedroom house range from $6000 to $10,000 to replace metal roofing with Colorbond, $15,000 to $20,000 to replace an asbestos roof with Colorbond, and $20,000 to replace a tiled roof with Colorbond.

Concrete tiles cost between $40m2 and $60m2, while tiled roofs cost between $80m2 and $120m2 depending on the pitch of the roof and other factors. If you opt for slate roofing, it may cost between $200m2 and $500m2.

While you have these figures in mind, these may not yet include additional expenses, such as structural work or the removal of the old roof.

Factors That Affect the Cost of Roof Repairs and Replacements

When repairing or replacing your roofing in Sydney, figure in the following factors when tallying up your expected cost:

1. Roofing Materials

Each roofing materials experience different roofing issues They also need different repair methods and expenses. If your existing roof is made from low-cost materials (e.g. asphalt shingles), the repair cost may be less expensive. If your existing roof uses metal sheeting, the repairs may be more complicated and come at a higher price.

2. Roofing Shape

The shape and size of the roof can greatly influence the costs of roof repairs in Sydney. If your roofing system has multiple levels, steep valleys, or complicated structures, it may go through a complex process. If so, it will require roofing contractors more time, work, and planning, which can increase labour costs and repair costs.

3. Roof Age

One of the factors that impact the cost of roof repairs is the age of the roof. Roofing systems that have worn out over the years require more costly repairs because they will not be as straightforward as they once were. They need thorough repairs to make sure their structural integrity is kept intact. On the contrary, newer roofs may only require a simple patch job.

4. Roof Location

Your location may also affect the overall cost of the roof repair. If you live near an area prone to high winds or corrosion, your roof may require a more thorough repair job to ensure it can withstand harsh weather conditions. Since the repair jobs required are more complicated, the costs will increase.

5. Scope of Project

The scope of your roofing project determines the total repair cost. If your roofing system has minor issues, you can expect less labour work and low costs. If the roofing problem proves to be big and complex, roofing contractors will likely charge you more.

The way you maintain your roof impacts the scope of the project. Homeowners can take plenty of preventative measures to protect their roof from roof damage and premature ageing. If you decide to take extra steps to prolong the life of their roofing system, you can help make roof repairs less complicated and less expensive.

6. The Roofing Contractor

Just like roofs, every roofing company is different. So, the cost of your roof repair or roof replacement in Sydney can vary depending on the service provider’s experience, quality of workmanship, and service area.

The costs can be inconsistent from company to company, so there is no set price for a roofing project. If you sought after high-quality roof repairs in Sydney, you should choose a roofing company with repair and replacement expertise. While these companies may charge more than others, their workmanship is worth the price.

The Bottomline

Knowing how much roof repairs and replacements cost and understanding the factors that influence the cost are important steps you need to take before any work begins. In that way, you can determine the nature and cause of your roofing problems and set a budget for the work that you will require.
