When it rains, water can collect on your roof and cause damage if it is not properly diverted. There are several effective and affordable options for diverting roof water to protect your home.

Gutters and Downspouts
Gutters and downspouts are the most common and effective way to divert roof water. Gutters are installed along the roof’s edge and collect water as it runs off the roof. The water then flows through the gutters and is channeled down downspouts, directing it away from the house’s foundation.
Gutters and downspouts come in a variety of styles and materials:
- Aluminum – Lightweight, durable, and affordable
- Galvanized steel – Strong and corrosion resistant
- Copper – Durable and aesthetically pleasing
- Vinyl – Low maintenance and long-lasting
When installing a gutter system, be sure to:
- Slope gutters slightly towards downspouts so water can drain effectively
- Space downspouts every 40 feet or less
- Direct downspouts at least 5 feet away from the house
- Use gutter guards to prevent clogs from leaves and debris
Routine cleaning and maintenance will help ensure your gutters and downspouts keep working properly.
Alternative Gutter Systems
While regular gutters and downspouts are the standard, there are alternative gutter systems that may be beneficial in certain situations:
Hidden Gutters
Hidden gutters tuck inside or directly against the roofline for a streamlined appearance. Options include:
- K-style – Angled gutter profile nestled just under roof shingles
- Half-round – Rounded gutter attaches flush to fascia board
Covered Gutters
Covered gutter systems fully enclose the gutter trough, helping prevent clogs from debris buildup. Types of covers include:
- Solid covers – Snug-fitting covers typically made of metal or plastic
- Gutter guards – Porous covers that allow water in while blocking debris
Seamless Gutters
Unlike sectional gutters, seamless gutters are custom-fitted on site from large spools of gutter coil. This creates a continuous waterway without seams.
Diverters
Diverters are devices installed directly on the roof that catch water and redirect it away from vulnerable areas. Options include:
Valley Diverters
Valleys are the angled intersections where two roof sections meet. Valley diverters cover the open valley seam, preventing leaks while diverting water to gutters.
Roof Aprons
Roof aprons install along the eaves (lower roof edges) to catch water running off the roof and channel it into gutters. This helps prevent leaks around gutters.
Eavestrough Diverters
Similar to roof aprons, eavestrough diverters sit just above the gutters and redirect water into the troughs. They help prevent overflowing gutters.
Alternative Runoff Collection Systems
In addition to standard gutters, some other systems can be used to collect and divert roof runoff:
Troughs
Roof troughs are like extra wide gutters installed along the eaves that catch large volumes of water. They’re connected to downspouts or drain pipes to divert water away from the house.
Built-In Gutters
Some roofs have gutters seamlessly built right into the overhang edges. The interior of the roof overhang serves as a long, continuous gutter.
Scuppers
Scuppers are openings cut into roof edges that allow water to drain directly off the roof without gutters. Water is then collected at ground level and diverted away from the foundation.
How Much do Gutters Cost?
When budgeting for new gutters, here are some typical price ranges:
| Gutter Type | Cost per Linear Foot |
|---|---|
| Aluminum | $3 – $6 |
| Galvanized Steel | $5 – $8 |
| Copper | $10 – $20 |
| Vinyl | $4 – $7 |
In addition, downspouts typically cost $20 – $40 each and gutter guards range from $3 – $7 per linear foot installed.
The total cost for a new gutter system on a typical single family home ranges from $800 – $2,500 or more, depending on factors like the roof pitch, size and style of gutters, number of downspouts needed, and any special installation requirements.
Maintenance Tips for Gutters
To keep your gutters functioning properly:
- Clear out leaves, sticks and other debris from gutters in the spring, fall, and after heavy storms
- Use a gutter cleaning tool or scoop to safely remove debris from the ground
- Flush gutters with a garden hose to remove stuck-on debris
- Make sure downspouts are clear and draining properly
- Check for leaks and holes, and patch any damaged areas
- Re-align gutters or tighten hangers if sagging or loose
- Consider gutter guards to reduce clogs from leaves and pine needles
Conclusion
Installing the right water diversion system on your roof protects your home from water damage and foundation problems. For most homes, a combination of traditional gutters, downspouts, and diverters provides an effective solution. Maintaining your gutters with regular cleaning and repairs can help maximize their effectiveness and longevity.
