Underlayment & Ice-and-Water Shield

Underlayment is the layer between your deck and the visible roofing material, and it is what actually keeps a roof watertight when wind drives rain sideways or a shingle lifts in a storm. Ice-and-water shield is a self-adhering membrane used at eaves, valleys, and other spots where water tends to collect or back up. In a Florida climate, this layer matters as much as anything on top of it.

What We Install

Synthetic Underlayment — A tear-resistant, water-shedding layer set across the full deck before any shingles or panels go down.
Self-Adhering Ice-and-Water Shield — Applied at eaves, valleys, and around penetrations, where wind-driven rain and standing water are most likely to find a gap.
Capped, Wind-Rated Fastening — Cap nailers and pneumatic coil nailers hold underlayment tight to the deck at the pattern Florida's wind-uplift standards call for.

How We Approach the Deck

Full Tear-Off First — Roofing shovels and tear-off spades strip old material down to a bare, inspectable deck so underlayment goes over sound wood, not old fasteners.
Layout Before Fastening — Chalk lines and laser distance meters keep courses straight so overlaps land where they should, not by guesswork.
Documented as We Go — Time-stamped photos of the underlayment and ice-and-water shield are taken before the finish material covers them, so there is a record of what is underneath.
