Skylight & Roof Penetration Sealing in Vallejo, CA

Skylight and roof penetration sealing in Vallejo means something different on Mare Island than it does anywhere else in our service area. These are century-old industrial buildings, and their daylighting is frequently original steel-framed monitors and sawtooth glazing rather than modern moulded domes on prefabricated curbs.

What skylight and penetration work in Vallejo actually involves

Those assemblies fail differently. The glazing bars, frames and fixings are steel, and salt-laden marine air off San Pablo Bay corrodes them continuously, so the failure is often structural in the frame rather than a degraded seal. Original putty and bedding compounds have usually reached the end of their life several times over. And because these are visible architectural elements on buildings inside a designated historic district, replacement in kind carries considerations that a warehouse dome swap does not. The practical approach is usually careful repair, corrosion treatment and reglazing rather than wholesale replacement, with the flashing where the assembly meets the roof rebuilt properly in compatible membrane. Elsewhere in Vallejo the work is more conventional, though the marine corrosion factor applies to every fixing in the city.

What changes on a Vallejo building

Original steel-framed monitors fail in the frame

Mare Island daylighting is often original steel-framed monitor or sawtooth glazing, and salt air corrodes glazing bars, frames and fixings continuously. The failure is structural in the frame rather than a degraded seal, which needs a different response.

Repair and reglaze rather than replace in kind

These are visible architectural elements on historic buildings, so careful repair, corrosion treatment and reglazing is usually the right approach. The flashing where the assembly meets the roof still gets rebuilt properly in compatible membrane.

Corrosion-rated fixings on every detail

Whatever the assembly, the fixings holding it down are in the most corrosive environment we work in. Replacement components need corrosion-rated specification or the repair fails at the fixing rather than the seal.
