Roofing Systems

The flagship of the line and the product most WatchGuard Roof work is built around. A pure polyurea roof membrane carrying Miami-Dade approval — the hurricane-zone standard that specifiers, building officials, and insurance carriers ask about before anything else.

It sprays over prepared metal, over roofing foam, and — with 7001 Primer — over existing single-ply and modified bitumen. It wraps curbs, pipe boots, drains, scuppers, and parapet terminations as one continuous piece, which means the details that leak on every other roof system are simply not present.

Where it is specified: low-slope commercial, standing seam and R-panel metal, TPO and EPDM restoration, agricultural storage and livestock buildings, and any roof where wind uplift is a design consideration.

Spec: 40–60 mil DFT over 7001-primed substrate; carried continuously up all curbs and terminations; aliphatic topcoat where long-term appearance is specified.

In hail country the failure mode is not water intrusion — it is impact. A hailstorm that dents panel is survivable; one that fractures a brittle coating opens hundreds of points for water to get under it at once.

Flak Jacket 1 is a higher-build polyurea with greater tear strength than the standard membrane. It absorbs impact energy and keeps its integrity where a thinner, harder film would craze.

It is also the right call on roofs that get walked regularly — around rooftop mechanical units, along service paths, and on walkable decks and mezzanine roofs where the membrane is being used as a surface rather than just a barrier.

Spec: FJ1 at 60–80 mil DFT over 7001-primed substrate, either across the full field in high-hail regions or as a reinforced band along traffic paths and around equipment.

A vehicle roof is a structural problem disguised as a roofing problem. It twists over every uneven road surface, it goes from −10°F overnight to 140°F on a summer afternoon, and it does all of this at seventy miles an hour with wind load on top.

The original EPDM or TPO roof on most RVs is joined and sealed at every seam, edge, and rooftop appliance, and those sealants are the single largest source of water damage in the industry. Once water gets into the laminated roof structure, the repair is not a roof repair — it is a rebuild.

Alasta Seal is a flexible polyurea membrane formulated for exactly this service: enough elongation to live with continuous flexing and enormous thermal cycling, sprayed continuously across the full deck and wrapped around every vent, AC unit, antenna, and skylight so there are no sealant joints left to fail.

Spec: clean, dry, and repair the existing deck · 7001 Primer over the full surface · Alasta Seal continuous across the deck, wrapped at all edges and penetrations.

Membrane alone fixes leaks. It does not fix ponding, and it does not insulate. Where the roof has drainage problems or the building needs continuous insulation, roofing-grade spray foam goes down first.

Foam is the only roofing insulation that can be applied thicker at low spots and tapered toward drains without a custom-cut board package. On a roof that ponds — which is most older low-slope roofs — that is the difference between fixing the problem and covering it up.

It also gives continuous insulation with no thermal bridging at fasteners, because there are no fasteners, and it produces a fully adhered monolithic substrate for the membrane to be sprayed onto.

Spec: prepare and dry the deck · roofing-grade closed-cell foam at 1–1.5" nominal, tapered for positive drainage · OR-80SLM at 40–60 mil DFT, same day where conditions allow. Foam is not UV stable and must never be left uncoated.
