What the AI looks for in Roofing Gutters
- Size
- Use 5 inch K-style as the standard size, and 6 inch for large roof areas, steep pitches or heavy-rain climates. Gutter capacity has to match the roof area and slope draining into it.
- Material
- Aluminum is the durable middle ground. Vinyl is easiest to DIY but becomes brittle in cold and UV. Copper and steel need matching fasteners and accessories. Material determines lifespan, expansion behavior and how parts must be matched.
- Aluminum thickness
- Prefer the heavier residential gauge, around .032 inch, over thin .025 inch stock. Thin aluminum dents from ladders and sags under ice.
- Joints and expansion
- Minimize seams, seal every connector with gutter sealant, and allow expansion joints on long vinyl runs. Joints are where sectional gutters leak, and vinyl expands substantially with heat.
- Hangers
- Use hidden or bracket hangers about every 24 inches. They hold far better than spike-and-ferrule hangers and prevent sagging.
Brands that matter
- Amerimax: Vinyl and aluminum sectional systems with a full range of accessories.
- Genova Raingo: Vinyl system that is simple to snap together.
What to avoid
- Vinyl gutters in climates with severe freezes
- Mixing brands of vinyl systems, since connectors rarely interlock
- Spike-and-ferrule hangers
Questions
Can I buy seamless gutters to install myself?
Seamless gutters are formed on site by a machine to the exact run length, so they are almost always contractor-installed. DIY options are sectional gutters.
