Built Smart, Even When Plans Change: How We Retrofitted a Box Gutter to an Insulated Flyover Roof

At SmartKits, we know great building is more than just using premium materials. It’s about smart thinking, experience, and problem-solving. When plans change mid-build, that’s when skill really shows.

This project started as a clean, modern insulated patio roof using elevated fascia brackets. Midway through construction, the client decided to fall the roof back toward the house. That meant one thing. A box gutter had to be added after the roof was already installed.

Not ideal. But with the right team, absolutely doable.

The Build: SmartKits Insulated Flyover Roof on Fascia Brackets

This patio used our insulated roofing panels, a 3-in-1 system with roofing, insulation, and a ceiling finish all in one. The roof was supported by elevated fascia-mounted brackets, a smart choice to gain height and airflow without bulky posts blocking windows or walkways.

This system delivered:

• A crisp, ceiling-like finish

• Built-in thermal insulation

• Fast install with no battens or ceiling lining

• Strong span capacity for open space

It was all going to plan until water management became the next challenge.

The Twist: Adding a Box Gutter After the Roof Was Installed

Once the roof was up, we saw significant water flow from two intersecting rooflines. A standard flashing wouldn’t cut it. The only option was a box gutter to collect and divert water properly.

Normally, box gutters go in before the roof sheets. Doing it afterward meant working under an already-built structure, modifying flashings, creating penetrations, and sealing everything without factory-finished edges.

This wasn’t a task for the unqualified. It required experience, precision, and the right tools.

The SmartKits Solution: Clean Retrofit with No Compromise

Our team cut and sealed a custom box gutter between the house wall and fascia brackets. It now captures all water from both roof directions and drains it through a neat dropper into stormwater.

The outcome:

• Leak-free

• Compliant

• Seamless appearance

This is why people choose SmartKits. We don’t just sell materials. We deliver engineered outcomes.
