Standing seam metal roof life expectancy.

Standing seam roof life expectancy.

We re working on a 120 year old house that still has its original standing seam metal roof. A roof painter told the owner that this roof has 50 years of useful life left. The seam sits between the metal panels at the highest point of the roof. A contrast to flat r panel metal roofs standing seam roofs feature angled roof panels.

It depends on the quality of installation but on average exposed fastener metal roofs which do indeed use edpm washers if not of very low quality and life expectancy are a 15 25 year roof while a quality standing seam job is a 50 year roof. Can a metal roof really last 170 years. A 30 year shingle roof actually may last up to 25 years if properly cared for or 12 15 years if it s not. Asphalt shingles on the other hand have an average life span of 17 years and a life expectancy range of 12 20 years according to state farm insurance.

The average lifespan of asphalt shingles ranges from 20 to 40 years depending on the manufacturer although many warranties only guarantee between 15 and 25 years. Some metal roofs can sustain wind gusts up to 140 miles per hour will not corrode or crack and may be impact resistant depending on which metal you choose. Most insurance certificates concerning the roof will mention a lifespan of 50 years which is considered to be the longest period that the metal will last. For our comparison we ll take the average and use 2 0 years.

In those days the options were copper lead tin coated iron and terne coated steel. Without complications the average lifespan of a standing seam metal roofing is considered to be 50 years or more. A rob haddock of the metal roof advisory council responds. The elevated seam is far less likely to leak leading to an increase in flat roof life expectancy.

If this roof is 120 years old that would mean it was built around 1880.
