DIY Under-Deck Drainage System
A low-cost and easy-to-build option for an under-deck drainage system is the one designed by Rune Eriksen, which uses corrugated fiberglass panels attached to purlins with special roofing screws, along with PVC gutters. This DIY approach not only helps maintain the structural integrity of your roof under deck but also creates a more appealing and functional outdoor living area.
Spacing 24 Purlins Parallel to the House at 3 ft. on Center Intervals
To begin constructing this drainage system, space out 24 purlins parallel to your house at intervals of three feet on center. These will act as support beams for the corrugated fiberglass panels that make up the roof under decks’ completed ceiling. Proper spacing ensures adequate weight distribution across all the boards while maintaining a consistent appearance.
Attaching Spacer Blocks to Deck Joists Before Attaching Remaining Purlins
Prioritize attaching spacer blocks made from treated lumber onto each joist before securing any remaining purlin supports in place using galvanized nails or screws. The purpose of these spacers is twofold: they provide additional support for dry space beneath your decking structure while allowing water runoff through gaps between individual boards.
Installing First Fiberglass Panel Using Roofing Screws

Installing a drainage kit for roof under decks is essential to ensure proper water flow away from the home and reduce potential damage. Proper gutter installation is also critical in order to prevent flooding and further structural problems, which will be discussed in the next section.
Proper Gutter Installation
It is crucial to install gutters and downspouts as part of your under-deck drainage system effectively directing water away from your home’s foundation while preventing any pooling beneath your decking structure itself. Ensuring proper gutter placement will optimize performance over time.
Importance of Correct Gutter Positioning in Relation to Roof Under Decks
The correct positioning of gutters plays a vital role in the overall efficiency and longevity of an under-deck drainage system. Gutters should be installed at a slight slope, typically 1/4 inch per 10 feet, allowing water to flow smoothly towards the downspout without causing overflow or backflow issues. Additionally, make sure that gutters are securely fastened with appropriate brackets or hangers for optimal support.
Tips for Successful Downspout Installation
- Select the right size: Choose downspouts that can handle the volume of water expected during heavy rainfall events based on your region’s climate conditions. A general rule is one square inch of downspout cross-section for every 100 square feet of roof area.
