Gutters last for a reasonably long time, but it depends on how you take care of them. Gutters are exposed to so much debris and waste that if they are not properly taken care of, they may need replacing sooner rather than later. For this reason, and many others, it is important to take care of gutters often to ensure that they are not falling into disrepair. If done, gutters can last for very long periods of time.
Gutters last about twenty years. This is, as stated above, a reasonable amount of time, but they are not guaranteed to make it so long. For example, location plays a part in the health of gutters. Because some locations produce more debris, gutters are exposed to harmful materials in greater amounts, which can be a serious detriment to their lifespan. This would mean that homeowners are looking at having to replace gutters years before they are supposed to be switched. In addition, if gutters are not regularly maintained at least twice a year, they will also fall into a level of inefficiency. The best way to keep gutters working, then, is to make sure they are properly serviced.
Just as bad care can shorten the lifespan of gutters, good care can lengthen it. For those who feel like spending the extra money and time, gutters can last for even longer than they are typically supposed to. Indeed, good care of gutters can allow them to last for much longer than twenty years, but this would involve regular gutter cleaning beyond the two recommended times every year. It would also mean spending more money for companies to take care of the gutters and keep them in great condition. Especially for larger homes, this practice might be too expensive and time consuming.
Most homeowners, however, if they work towards keeping their gutters clean and free of waste, can expect to see their accessories lasting for a full twenty years. Again, this sounds like a long time, but there are many people who live in homes for decades and pass them on to their children. When that is considered, changing the gutters every twenty years seems like more time than initially thought. Indeed, gutters do need maintenance to get their full lifespan, but homeowners do not have to go above and beyond to get to that point.
As long as gutters are properly looked after, they will last for long periods. As mentioned above, there are some unknowns that could impact the life of the gutters. The weather and location both have an impact on gutters, and homeowners need to figure out how many times they need to be having their gutters cleaned every year. It is and always will be a useful endeavor.
