Roof-Over & Overlay Installation

A roof-over, or overlay, installs a new roofing layer directly over an existing one instead of tearing the old roof off first. Homeowners typically consider it when a roof has one layer already down, the deck below is sound, and the goal is a faster path to a refreshed roof surface. Whether an overlay is the right call depends on what is actually happening underneath the surface, which is why that step comes first.

Checking What's Underneath

Core Sampling Tools — Test cuts show exactly how many layers are already on the roof and whether wet insulation is hiding underneath.
Moisture Meters — Direct readings across the deck separate a dry roof from one holding water that an overlay would seal in.
Handheld Infrared Cameras — Thermal scanning finds wet insulation and hidden leak paths before a new layer goes down over them.
Drones with Thermal & High-Res Cameras — Aerial imaging reviews the whole roof surface for damage without foot traffic on it.

Planning and Documentation

Aerial Measurement Platforms (EagleView) — Aerial measurement reports give exact material counts before the overlay begins.
Photo Documentation Apps (CompanyCam) — Time- and location-stamped photos of the roof's condition and each stage of the work, so you see what we see.
