Roof Installation: Factors that Affect a Roof’s Longevity and Durability

12 April 2023

Roof installation done right offers a lot of benefits, likewise, a properly maintained, high-quality roof can continue to offer exceptional protection and performance for decades. As a company that specialises in a variety of roofing solutions for both residential and commercial buildings, we are here to discuss everything that might extend or shorten a roof’s lifespan.


Asphalt shingle is the most common type of roofing material used in Australia. Asphalt shingles provide the best balance of attractiveness, longevity, and energy efficiency. Regarding durability, though, asphalt shingles aren’t even close to being on par with tile or metal roofs.

The Components & Pitch

The elements of nature are the greatest threat to the integrity of any roof. Even while roofing systems are designed to endure damaging and corrosive elements, high winds, torrential downpours, and hailstones can ultimately take their toll on even the most durable roofing system.

The angle at which a roof is pitched determines how effectively it drains water. Every resilient roofing system has a maximum amount of ponding water that it can withstand before losing its strength. This limit varies from system to system. Because of this, it is recommended that low-slope roofs use flat roofing systems rather than sloped roofs.

Sun Exposure

Heat hastens the process of wear and tear, particularly when the roofing material is dark in colour since this causes it to absorb more energy, which in turn causes it to become hotter. Intense UV radiation increases roof disintegration. Fortunately, several roofing systems are intended to protect against UV radiation efficiently without compromising their attractive appearance.


Insufficient ventilation in the attic may cause the roofing materials, particularly asphalt shingles, to heat up inside. In addition, it results in condensation, which in turn makes the wooden roof deck more susceptible to damage caused by moisture.

Isolation And Soundproofing

The temperature in your home’s attic may skyrocket if it does not have sufficient insulation. When combined with inadequate ventilation, keeping the temperature in your attic at a comfortable level is exceptionally challenging.

Installation, Maintenance, and Roofing Age

Errors in artistry are the leading reason for roofs failing before their expected lifespan. Even if you select the roofing material with the finest quality available on the market, improper installation can still result in early degradation, which will need you to replace the roof earlier than expected.

Even the most durable roofing systems require maintenance and upkeep as any other roof does. If you do not properly maintain your roof, you should not expect it to live up to its full lifespan since it will likely fail before then. In addition, if you do not perform certain maintenance tasks as directed, you risk invalidating the warranty purchased with the product.

Eventually, even the most long-lasting and well-maintained roofs will succumb to the effects of time, no matter how well they are cared for. When it comes to providing maintenance for an older roofing system, you should always consider the system’s age to make a financially sound decision. Sometimes it’s not worth saving an old roof if it’s not in good enough shape.
