Quick answer

Commercial roof replacement in San Jose removes a roof that has reached the end of its working life and installs a new system, usually torch down or TPO on a flat or low slope building. Golden Sky Roofing Inc, CSLB #1160249, Class C-39, plans the work with property managers, HOAs and owners and puts the scope and price in a written proposal.

When a commercial roof needs replacing

  • Repairs keep recurring in different places
  • Water has soaked the insulation or damaged the deck
  • The surface has failed across most of the roof
  • The roof is old enough that repairing it no longer makes financial sense

Not sure whether the roof is at the replacement point? A free on-site estimate tells you whether repair or replacement fits, and a paid roof inspection documents the roof’s condition if your board wants it on paper. For local problems, see commercial roof repair.

Replace or restore

A silicone roof coating can restore a flat roof that is still sound. If we find wet insulation or a failed surface, we tell you a coating will not hold and walk you through a commercial re-roof instead.

Systems we install on commercial roofs

We go through both with you and recommend the one that fits the building, its roof details and how the roof is used.

How a commercial replacement is planned and run

  1. 01Phone consultation. We learn about the building, the roof and who approves the work.
  2. 02Free on-site estimate. Anthony Rivera, Sales and Estimating, walks the roof with you and talks through your options, including the deck and insulation.
  3. 03Written proposal. The system, scope, materials and price are in writing.
  4. 04Schedule. Start dates and any access or notice requirements go into the plan with you.
  5. 05Installation. The proposal states what comes off and what stays. The deck and insulation are repaired where needed, and the new system is installed.
  6. 06Final walkthrough. We review the finished roof with you and hand over warranty paperwork in writing.

Golden Sky Roofing Inc pulls the permits for the job and adds the cost to the estimate, so the permit line is already in the proposal your owner or board reviews.

What owners and boards receive

Replacement is a large decision for an owner or a board, so the paperwork is built to be shared. You receive a written proposal, sent by email, with the scope, the system and the price, payment terms in that proposal, and warranty terms in writing before work starts. Our work carries a 5 year workmanship warranty plus the manufacturer’s limited product warranty. Golden Sky Roofing Inc holds CSLB #1160249, Class C-39 (Roofing), and is owned and run by Jose and Luz Dominguez.
