An indispensable component of a roof system, gutters protect the roofing and foundation of a home or business from damage from rainfall. If water fails to drain properly from a roof, it will contribute to leak formation. It will also damage your fascia and walls from run-off. As it collection around your foundation, you can furthermore expect slab leaks and other problems. From an energy efficiency perspective, the damage caused through poor drainage can penetrate a structure’s thermal envelope, leading to the lost energy that raises your monthly bills.
