Real Questions Our Customers Ask us every day. Browse by Product Below, or Call/Text 800-517-5246 if you don’t see your Question here.
Section 1: Box Gutters
Depends on your roof size, pitch, and rainfall. 6″ fits most homes; 7″–9″ suits larger homes and heavy-rain areas. Call us and we’ll help you pick.
Standard is our classic profile (6″–9″). True Box (7″–8″) has a more modern face. Slanted/Angle Box (7″–8″) fits specific rooflines. All perform equally well.
Aluminum is affordable and most popular. Steel/Galvalume suits heavy-duty commercial jobs. Copper is premium — costs more, lasts decades.
6″ needs 15″ or 18″ coil, 7″ needs 18″, 8″ needs 20″, 9″ needs 24″.
Section 2: Half Round Gutters
Just the curl direction on the front lip. Euro Curl is the traditional European look; Reverse Curl curls the other way. Same performance, different style.
6″, 7″, and 8″. Our 7″/8″ are named profiles: OnSite/HR7.5 and HR8.5, both 15″ coil.
Yes — Aluminum, Copper, and Galvalume all available.
Section 3: K-Style Gutters
Decorative crown-molded front, the most common residential style in the U.S. Carries slightly less water than box gutters.
7″ and 8″, in Aluminum and Copper.
Section 4: Gutter Hangers
Both are .080″ aluminum. Double-ribbed adds strength for heavy loads or snow-heavy regions. Standard works fine for typical homes.
Yes — .095″ thickness, fits 6″–8″ profiles.
Depends on gutter size and local snow/water load. Call us or check your local building code for exact spacing.
Section 5: Downspouts & Elbows
Smooth, Square, Round, and Corrugated — plus matching elbows.
4×4 and 4×5 are most common; custom lengths available on smooth and corrugated.
Smooth is cleaner-looking and our default recommendation. Corrugated adds rigidity for high-wind areas.
Bigger gutters need bigger downspouts. Tell us your gutter size and we’ll recommend the right match.
