Gutters are the drainage system that moves rainwater off your roof and away from your home's foundation. Without them — or with gutters that are failing — water runs down your fascia, pools against your foundation, erodes your landscaping, and eventually works its way into your basement or crawl space. Quality guttering isn't just an accessory; it's a critical part of protecting the whole structure. In Texas, where storms dump heavy rain fast, gutters that can't keep up cause real damage.
