Frequently Asked Questions

Reroofing Explained

Re-roofing refers to the process of removing an existing roof covering, repairing any damage to the framing or substrate (this may include replacing roof trusses and support battens or purlins), removing and replacing existing underlay and installing a new roof covering. This may be done for aesthetic reasons – to freshen a house up for sale, or simply to update the look of your forever home – or it may be done to address underlying issues such as rot or water damage to the roof structure, wall lining and ceiling. Replacing your roof is the best way to prevent further damage to the internal structure of the house and the costly repairs that follow.
Repair or Replace

Choosing whether to repair a leaky roof or replace it entirely is one of the biggest decisions homeowners face when it comes to general maintenance of their property exterior. The decision is generally influenced by cost factors – repairs versus replacement – but also needs to take into account the lifespan of the roof, and whether or not it has enough serviceable life left in it to merit ongoing repairs.

Typically, a house will only need two full roof replacements in its lifetime – this is when the entire roof is stripped back and all elements are replaced with new roofing materials ie: roofing sheets, flashings, fixings and underlay.

Minor or ongoing repairs is generally sufficient for a newer roof which may be experiencing some localised leaks or spot failure. However, if any rot or damage to the substrate is found, it can quickly become a much larger job than first thought. If you are in any doubt, it is always recommended to seek professional opinion from a roofing specialist in order to avoid unexpected surprises down the track. If your roof has required a number of repairs over a period of several years, or if it continues to leak in certain spots regardless of previous attempts to repair, it is highly likely that it is time to consider a full roof replacement.

As a general rule – replacement rather than repair is recommended for any roof which is over 30 years old – at this point the roof is nearing the end of its serviceable life and attempts at patching are likely to cause additional problems to those they were intended to fix.
Considering The Costs

The cost of replacing a roof isn’t solely determined by its size in square meters. It’s crucial to get a comprehensive quote from a professional roofer that considers all aspects specific to your project. Relying on a simple square meter rate can be misleading if it doesn’t encompass all necessary factors. At Aspect Roofing, we offer free, no-obligation quotes tailored to your needs.

While it might seem economical to continue making repairs to extend your roof’s life, frequent walking on an aging roof or disturbing its materials can create new leaks beyond those you’ve patched. Though repairing may seem cheaper initially, if your roof is approaching the end of its viable lifespan, these fixes only delay the inevitable. Moreover, recent safety regulations have made minor repairs more costly, often necessitating expensive scaffolding or access requirements. Cumulatively, these expenses can exceed the cost of a roof replacement in the long run.
Cost Affecting Factors

Factors influencing roofing costs include:

Materials: Choosing between longrun metal or tiled roofs, and deciding between standard or marine-grade coatings impacts costs.

Roof Pitch: Lower slopes generally mean lower costs compared to steeper pitches.

Height: Taller roofs typically incur higher expenses due to increased materials and labor requirements.

Accessibility: Considerations such as delivery access, site accessibility, and ease of roof access affect overall costs.

Labor: The complexity of the roof design and the estimated time for completion influence labor costs.

6. **Location**: Proximity to the sea may necessitate marine-grade coatings, which are more costly. Rural locations might incur extra charges for material delivery.

7. **Special Equipment**: Requirements like cranes for material lifting or specialized trucks impact costs.

8. **Safety**: Depending on safety needs like full scaffolding or edge protection, and any necessary electrical isolations, expenses may vary.
Will insurance cover the costs

Typically, home insurance policies will reimburse the cost of repairing or replacing your roof due to sudden, unforeseen events or natural disasters. This coverage extends to incidents like a tree falling on your roof during a storm, damaging cladding sheets, where repairs are necessary.

However, gradual wear and tear or deterioration over time is not covered by insurance. For example, internal damage caused by a long-term leaking roof that has exceeded its expected lifespan falls under maintenance responsibilities and would not qualify for insurance coverage.
When it’s time to act

Homeowners bear the responsibility of maintaining their roofs to ensure longevity. Regular inspections and upkeep play a crucial role in achieving this. Tasks like clearing gutters, pruning trees, and annually washing areas not reached by rainwater are essential.

As a guideline, signs such as rust, deterioration of soft edge mesh under the ridge, missing or protruding fixings on roof sheets, lifting laps on sheets, or horizontally overlaid short sheets indicate potential issues. Seeking professional assessment can provide insight into the roof’s condition and guidance on when re-roofing may be necessary.
Build to last

After re-roofing, your roof should last at least until the end of the manufacturer’s specified warranty period, which your roofing installer will provide upon completion of the work. Typically, roofs are expected to exceed this base warranty period significantly. However, weather conditions and climate can impact lifespan, especially if specific environmental guidelines, such as those for sea spray or industrial emissions, aren’t followed. Here’s a rough estimate of expected lifespans for different roof types, which can vary based on climate and exposure:

– Longrun metal / metal tile roofing: 40+ years
– Membrane / rubber roofing: 30+ years
– Composite tile / shingle roofing: 12-20 years
– Asphalt shingle roofing: 15-20 years

The roof structure itself should endure for the duration of the house’s lifetime and typically doesn’t require replacement when new roof coverings are installed. However, this assumes the external cladding remains watertight throughout its lifespan without prolonged exposure to leaks.
A sound investment

While the initial expenses of a significant renovation like re-roofing might seem intimidating, it’s one of the most worthwhile investments for your home’s future security. A new roof typically guarantees at least 30 years of protection, ensuring your family’s comfort and safety for decades. Additionally, if you’re considering selling, a fresh roof enhances your home’s value and curb appeal. A well-maintained exterior gives your property a competitive edge in the real estate market compared to similar listings.
