Flat roofs fail at the seams. So that's where we spend the time.

Silicone restoration for flat roofs that are sound but tired, torch-down replacement for the ones that aren't. Either way the seams, curbs and penetrations get the detail work first, because that is where every flat roof leak starts.

What happens when you call:

  • We walk the roof and check the substrate. Dry and sound means restoration; wet means replacement. We tell you which before we price anything.
  • You get a written scope with the prep, seam work and coats spelled out, not a per-square number with nothing behind it.
  • Drainage problems get fixed, not coated over.

How We Do It

Silicone Restoration, Step by Step.

The finished roof is a smooth gray or white field. Everything that makes it last happens before the first coat.

1. Clean and dry

Degrease and pressure wash the whole roof, then let it dry completely. Coating over dust or damp is how restorations fail in a year.

2. Three-course every seam

Mastic, polyester mesh, mastic, at every seam, vent, curb, pipe and drain. Full cure before anything goes over it.

3. Primer and two coats

Primer, then two coats of silicone applied in good weather and checked for thickness, so the system reaches its rated build.

Flat Roof Questions

What Flat Roof Owners Ask Us.

Is a silicone coating a real roof, or a patch?+

A silicone restoration is a roof system: cleaned substrate, every seam and penetration reinforced with a three-course treatment, primer, and two coats of silicone. Applied over a sound flat roof it adds years of service. It is not a fix for a roof that is already saturated or structurally failing; we tell you which one you have before we price it.

When is silicone the right call, and when do you tear off?+

If the existing roof is dry underneath, drains, and the seams are intact or repairable, restoration is the better buy. If the insulation or deck is wet, or the roof has been coated before and is failing, torch-down replacement is the honest answer. A core cut or moisture check settles it.

What is the three-course detail you keep mentioning?+

Every seam, vent, curb and pipe gets a bed of elastomeric mastic, polyester mesh pressed into it, and a second coat of mastic over the top, before any primer or silicone. Those white stripes are what keep the roof from opening at the seams. It is the slow part of the job and the part that decides whether the coating holds.

Do you install new flat roofs too?+

Yes. Torch-down modified bitumen and two-ply systems for new flat roofs, patio roofs, and the low-slope sections many Ventura homes carry, with new Z-metal, drip edge and curb flashings. See the Oxnard partial re-roof.

Does it come with a warranty?+

Our workmanship warranty covers the restored section and the flashings we install, in writing on the estimate. Resealing of existing flashings elsewhere on a roof is maintenance work and is called out separately so there is no confusion about what is covered.
