Gutters systems can last 20-30 years, but that doesn't mean they'll never need repairs. The first step to extending the life of your gutters is regular gutter cleaning. But let’s suppose you already have damaged gutters. While many problems can be repaired, sometimes you just need to go ahead and replace your gutters.
The main factor in determining whether to repair or replace your gutters will be extent of damage. If you only have one or two trouble spots, they should be easy to fix, but if multiple sections of your gutters are giving you problems or you have tried repairing a problem before and it keeps coming back, you should save yourself the headache and replace your gutters.
