How To Know How Long Your Roof Will Last

How To Know How Long Your Roof Will Last

Repairing or replacing your roofing system can be a costly proposition. So, it’s important as a homeowner to understand the life expectancies of different roofing materials to make an informed choice when investing in a new roof. Here is a quick roundup of how long various residential roofing materials last.

Asphalt Shingles

An asphalt shingle roof lasts around 15 to 25 years when properly maintained and barring significant storms or disasters. However, you will need to have your roof thoroughly inspected by a professional around the 15-year mark, especially if your roof has faced a major weather issue.

If you suspect your asphalt shingles might need repairs or replacement, look out for major cracks, curled shingles around the edges, or missing granules. A hailstorm, tornado, blizzard, or other catastrophic weather event could shorten the lifetime, prompting untimely repairs or replacement.

Metal Roofing

Metal roofing systems are becoming increasingly popular for residential homes, thanks to their longevity. With proper installation and maintenance, metal roofs can last for decades. Typically, a metal roof can last for up to 50 years or even longer if it is well cared for and no major storms or other problems occur. In fact, copper or zinc can remain beautiful and fully functional for 100 years, making their high upfront cost well worth the investment.

Low Slope and Flat Roofing

If your home has a flat or low-sloped roof, a roofing membrane such as EPDM can be an ideal choice due to its low cost and ease of installation and repair. However, EPDM roofs only last 5-15 years and are prone to leakage due to their glued or taped seams. TPO or PVC roof membranes are more costly but relatively more durable alternatives for flat or low-sloped roofs.

Cedar Shake and Wood Shingles

Cedar roofing offers an elegant and timeless appearance. It’s highly rot and insect-resistant, making it last for decades or even longer with proper maintenance. Typically, cedar shingles or shakes can last 30-40 years depending on the climate, level of maintenance, and presence of any overhanging trees which can cause faster deterioration. When you begin to notice cedar shingles or shakes peeling or cracking, then you know it is time to consider repairing or replacing your roof.


Tile roofing systems are popular in warmer, wetter climates due to their impressive heating and cooling efficiencies and water resistance. The lifespan of your tile roof will largely depend on the specific type of tile you choose and the prevailing weather conditions in your region. Overall, tile roofs can last 100 years or longer with proper care.

While the lifespan of your roof will largely depend on the specific roofing material you choose, the installation technique and maintenance routines will significantly shorten or prolong the life expectancy of your roof.
