When choosing a new roof for your home or a commercial project, metal fascia for a modern roof gets the preference. Why? It is highly durable and long-lasting. Speaking of durability, the first thing that comes to mind is how long the metal roof will last. There is no denying that metal roofs have a lot of benefits, but the most important value they offer is their longevity.
The Average Lifespan of a Metal Roof
A steel roof can easily last 40-60 years. Metal panels like copper or zinc can last even longer, 70-100 years. Copper and zinc are the most expensive types of roofing, and they are hard to find. Metal roofs bring the highest value for money because they are affordable and are also considered “lifetime roofs.”
What Makes the Metal Roof Last?
The durability of metal enhances the longevity of the roof. It increases resistance to the elements that can cause major damage to weaker roofing materials like shingles. Metal has superiority in the following areas:
1. Class 4 impact resistance – The materials that have class 4 resistance are the most impact resistance.
2. Wind uplift
3. Class A fire rating – Class A fire rating ensures that the roofing materials are the most non-combustible.
4. Resistance to termites and pest
5. Resistance to mould and mildew
6. Corrosion resistance
What Are Some of the Factors that Affect the Longevity of the Metal Roof?
There are certain factors that impact the longevity of the metal roof. These include:
1. Proper installation
2. Climate
3. Maintenance
4. Gauge
5. Paint finish
Proper Installation
Any roof that is not installed correctly will have problems. Metal roof installation is not an exception. Nominal installation errors, like over-tightening fasteners or not using the roofing underlayment when required, lead to damage and roof repair. Proper installation helps ensure a metal roof that will last a long time.
Climate
Weather plays a vital role in how long the metal fascia for a modern roof will last. Choose the right type of roof for the weather. It is crucial for harsh weather conditions like heavy snow and extremely high winds. These elements can take a heavy toll on any roof, not just metal. These areas need a roof that can handle the stress from the elements. Choosing such a metal panel that is right for your area helps ensure that the metal fascia for a modern roof last for a long time.
Maintenance
Metal roofs only need minimal maintenance. However, proper maintenance from time to time helps make the roof last a long time. If a small problem starts to form, a routine inspection will help identify what’s going on before it becomes a major problem. Problems that are not detected result in expensive repairs or roof replacement.
Gauge
The correct metal gauge on a roof helps ensure longevity. Corrugated metal roofing is used in 29, 26, and 24 gauge thicknesses and standing seams are usually 24 gauge in thickness. Thicker gauges are available, and they must be used if the roof will be exposed to extreme weather. The lower the gauge number, the thicker and more durable the metal will be. Thicker metal offers the roof more strength to handle snow load and more weight to resist the wind and uplift during heavy storms.
Paint Finish
The paint finish is another crucial element that determines the durability of the metal panel. The paint finish for the metal panels comes in a PVDF or an SMP paint finish. PVDF is a superior finish that ensures higher chalk and fade resistance. The metal fascia for a modern roof with a PVDF paint finish doesn’t increase the longevity of the metal roof, but it does prolong the aesthetic life of the roof. Face and chalk resistance helps to maintain the desired appearance of the metal roof, especially when it is about maintaining vibrant and bright colours that can fade away after a certain time.
