Short answer. A valley splash guard is a piece at the gutter intended to catch water a steep valley throws past the front lip. On tile roofs in Orlando and Sarasota subdivisions, the valley, the tile profile, and the gutter opening decide whether that piece belongs. It is not a substitute for pitch, outlets, or downspouts.
Overshoot is a path problem at the valley.
A steep tile valley can send a sheet off the tile and past the gutter, even when the trough itself is clear. A splash guard at that corner is one way to interrupt the sheet. It works only if the water can then enter the gutter and leave through an outlet. A guard that bounces the sheet somewhere else is not a fix. This page does not publish a percentage of water caught.
Plumbing code sizes gutters from roof flow. It does not name a splash guard.
Florida Building Code, Plumbing, section 1106.6, read on the UpCodes copy of the 2023 code, says horizontal gutters shall be sized based on the flow rate from the roof surface, and that the flow shall not exceed Table 1106.6. Section 1106.1 sizes vertical conductors and leaders on the 100-year hourly rainfall rate in Figure 1106.1 or on approved local weather data. This page does not copy a rainfall number or a table cell. A splash guard is not in those sentences. SMACNA’s calculator asks for intensity, area, length, and downspout count together. PrimeFlow does not publish a calculator result here.
- Which valley, and which roof planes feed it.
- Whether the gutter lip is inside the sheet or outside it.
- Whether the outlet downhill of that corner is open.
- Whether a larger profile is a separate question from the splash piece.
Orlando tile and Sarasota tile are separate visits.
Both markets have subdivisions with steep tile and long valleys. The houses, the access, and the storm pattern are not interchangeable. Orlando uses the Orlando tile-roof page and (407) 902-7639. Sarasota uses the Sarasota tile-roof page and (941) 404-3901. NWS Melbourne is the east-central pattern. NWS Tampa Bay is the Gulf-coast pattern. Neither is a design rainfall for one valley.
Do not assign 7-inch from the tile
Six-inch is a common residential starting point. Seven-inch is reviewed when the roof demand supports it. Tile alone does not assign either size, and a splash piece does not replace that review.
The piece is gutter work. The tile is not.
PrimeFlow does not repair tile, flashing, or the valley metal. If the overshoot is a flashing or a tile problem, that trade is coordinated and kept out of the gutter scope unless a written agreement says otherwise. Walking a tile roof to prove a splash path is not required for the estimate.
The estimate names the corners. It does not name a success rate.
What changes the work is how many valleys throw water, the gutter profile, the outlet count, and access on tile. This page does not publish a price. Work is scheduled after a written scope and the required deposit, unless a written waiver says otherwise.
