How Long Should A New Roof Last?

There is no one answer to how long your roof should last, as various factors will influence its lifespan. These include,

  • Materials used
  • Ventilation
  • Roof colour
  • Installation
  • Location

Different Roofing Materials & Potential Lifespan

Ashfelt Roofing Material

15 -25 years is the period typically expected for a shingle ashfelt roof. Your location will influence how long it will last. High winds and heavy snowfall are the most significant problems. If you live in an area that experiences this type of weather, higher-grade shingles will be your best option. 

Three-tab shingles can withstand a maximum wind lift of 60 -70 MPH and a lifespan of 10 – 20 years. Dimensional or architectural shingles will withstand a wind lift of up to 130 MPH and a life span of 15 – 25 years. Premium or high-impact resistance shingles are category level 4 and have a life expectancy of 20 -30 years.

Metal Roofing Material

You can construct a roof with various metals. The lifespan varies according to the metal used. These can include,

  • Ribbed metal panels, with an expected duration of 25 – 40 years.
  • Stone-coated steel tiles, with an anticipated duration of 30 – 50 years.
  • Stainless steel, titanium, zinc and copper are premium metals for roofs and can last up to 100 years.

Clay & Concrete Roofing Materials

Both of these materials have an expected duration of up to 100 years. Clay is the longest, with an expected lifespan of 100 – 150 years. Concrete has a lifespan between 40 – and 75 years.

Wood Shingles

Ceader and shake shingles are amongst the most aesthetically pleasing roofs. They also last around 20 – 40 years. Cedar is popular due to its insect and rot resistance, although Oak is a durable alternative.

Alternative Roofing Material & Expected Duration

  • Natural Slate has an expected lifespan of 50 – 100 years.
  • EPDM roof has an expected lifespan of 5 – 15 years.
  • Composite roofs have an expected lifespan of 30 – 50 years.
  • PVC and TPO membranes have an expected lifespan of 20 to 30 years.

Ventilating Your Loft

A well-ventilated loft keeps your roof cool, preventing the creation of ice dams caused by snow and ice melting on the roof. Ice dams happen when the snow melts during the day and refreezes overnight. After several days, the melted water and ice will work under the shingles, letting water enter the loft. Ice dams cause problems to your roof, ceilings, walls and contents.

Consider Your Roof Colour 

A darker-coloured roof absorbs more heat; excess heat will damage your roof eventually, whereas a lighter-coloured roof will last longer.

Geographical Location

The UK experiences different weather in different areas. As previously mentioned, the roofs in areas prone to high wind speeds, heavy rain or snowfall will experience a reduced lifespan of their roofs.
