That’s a reasonable estimate based on architectural shingles, although 15 years is more likely in latitudes with more solar exposure throughout the year (the Sunbelt in the US). Metal roofs last longer, but have a higher initial upfront cost. Huge fan of metal standing seam roofs for longevity (40-70 year lifetime) as well as robust mount support (clipping to the seams) for solar racking.

This thread has loads of people talking about roofs lasting 50-100 years https://forums.moneysavingexpert.com/discussion/5575330/when...

Yes, there are types of roofs that last a long time. Standing seam metal, slate, clay, concrete, and copper roofs all last a long time (50+ years). Asphalt shingles and EPDM flat roofs last 15-25, cedar shakes can last 30+ years.

The long lasting ones are substantially more expensive than asphalt shingles, 3x at a minimum.

My estimate is what home insurers use. Roofs can and do last longer.
