Quick Answer
Instead of traditional gutters, consider using a drip edge, a fascia board, or a French drain system for rainwater collection. These alternatives can effectively channel water from the roof into a collection system. They are often more cost-effective and low-maintenance.
Alternative Gutter Options
Drip Edges: A Low-Cost Solution
A drip edge is a simple, cost-effective solution for collecting rainwater. It consists of a metal or plastic edging attached to the roof’s eaves, which directs water into a collection system. To install a drip edge, attach it to the roof’s fascia board, ensuring a 1/4-inch overhang to prevent water from seeping behind the edge. A 2-foot length of drip edge costs approximately $10, making it an affordable option for rainwater collection.
French Drains: Effective for Heavy Rainfall
A French drain is a trench filled with gravel and a perforated pipe that directs water away from the building. To use a French drain for rainwater collection, install a 6-inch deep trench along the roof’s edge, filling it with 2-3 inches of gravel. Place a 1/2-inch perforated pipe in the trench and connect it to a collection system. This design is ideal for areas with heavy rainfall, as it can handle large water volumes.
Fascia Board Collection Systems
A fascia board collection system involves attaching a series of troughs to the roof’s fascia board, which direct water into a collection system. To install this system, use a 1/2-inch thick fascia board with a 4-inch wide trough, spaced 12 inches apart. Attach the troughs to the fascia board using 1-inch screws, ensuring a watertight seal. This design is suitable for smaller rainwater collection needs, such as irrigation systems.
