Maitland homeowners replacing a roof tend to focus on the shingle product they can see from the street. The product selection matters, but the components beneath the shingles determine how the roof actually performs when Central Florida's afternoon thunderstorms arrive with wind-driven rain or when a slow tropical system stalls over Orange County and delivers rain for days. A high-quality shingle installed over a compromised or code-minimum underlayment system is a better-looking roof with the same vulnerability. Understanding what goes under the shingles changes how the installation is evaluated and what questions to ask a contractor.

Roof Decking: The Foundation Everything Else Attaches To
The roof deck is the structural panel system, OSB or plywood, that covers the rafters and provides the nailing surface for every component above it. In Maitland's year-round heat and humidity, deck condition matters more than in drier markets. OSB decking that has absorbed moisture from a prior leak or from inadequate attic ventilation loses its structural integrity over time, and shingle fasteners driven into compromised OSB do not hold under wind uplift the way they do in sound material. Deck inspection during tear-off is where deck replacement decisions are made, and those decisions affect everything above.
Underlayment: The Layer That Protects When Shingles Are Compromised
Underlayment is the layer installed directly over the roof deck before shingles go down. In Florida, the underlayment is not just a backup barrier. It is a primary defense layer during the tropical weather events that Maitland receives through hurricane season. Florida building code requires more robust underlayment than many other states specifically because the wind and rain conditions here test the system at a level standard code in other markets does not address.
Self-adhering modified bitumen underlayment, used in Revildor's CertainTeed system installations, bonds directly to the roof deck and seals around fasteners, closing the gaps that standard felt or synthetic underlayment leaves at nail penetrations. Under the high wind conditions of a tropical event, water can be driven upslope under lifted shingles. A sealed deck system catches that water before it reaches the wood.
Ice and Water Shield at Valleys and Eaves
Ice and water shield is a self-adhering membrane installed at high-risk areas of the Maitland roof before the main underlayment goes down. Valleys, where two roof planes intersect and water concentrates during heavy rain, are the primary application point. Eave edges, where water can back up under shingles during a prolonged rain event, also receive ice and water shield coverage in a properly installed CertainTeed system. These are the locations where water entry is most likely during the sustained heavy rainfall events that Central Florida tropical systems deliver.
Drip Edge: The Component That Protects the Fascia
Drip edge is a metal flashing profile installed at the eave and rake edges of the Maitland roof that directs water away from the fascia and into the gutter rather than allowing it to run back under the shingle edge and contact the wood below. A roof without drip edge or with deteriorated drip edge allows water to wick back against the fascia repeatedly during rain events, which is one of the most common causes of fascia rot on Central Florida homes. Florida code requires drip edge on residential installations, and Revildor installs it on every Maitland project.
Flashing: The Transition System at Every Joint
Flashing is installed at every location where the roof plane meets a vertical surface or where two roof planes intersect. Chimney flashing, step flashing at wall-to-roof transitions, valley flashing, and pipe boot flashing at every penetration through the Maitland roof surface all serve the same purpose: direct water away from the joint and prevent entry at the transition point. These are the highest-risk locations on any roof, and the quality of the flashing installation at each determines how long the roof performs without developing a leak at those points.
