Residential, Commercial and Industrial Roof Replacement
GENERAL ROOFING COMPANY HAS INSTALLED COMPLETE ROOF SYSTEMS SINCE 1924
General Roofing Company provides complete residential, commercial and industrial roof replacement in Oakland and throughout the greater San Francisco Bay Area. Since 1924, we have installed durable roofing systems for homes, businesses and industrial properties using materials selected for each building, budget and application.
Our Diamond Certified, licensed and insured roofing team continually trains in modern installation methods and manufacturer requirements. Every project begins with a careful assessment of the existing roof so we can recommend repair, maintenance or complete roof replacement based on its actual condition.
When Is Roof Replacement Necessary?
Not every roof problem requires replacement. However, a complete roof replacement may be the most reliable solution when the existing roof has widespread deterioration, recurring leaks, damaged decking or membrane, or has reached the end of its expected service life. General Roofing Company evaluates the complete roof assembly and explains whether repair, restoration or replacement offers the best long-term value.
Our Roof Replacement Process
01 · Roof Assessment
We inspect the roof covering, decking, flashing, drainage and penetrations to identify damage and determine whether replacement is the right solution.
02 · System Selection
We recommend the appropriate roofing system and provide a clear scope covering materials, scheduling and the work required for the property.
03 · Professional Installation
Our trained crew prepares or removes the existing roof, repairs damaged substrate and installs the new system to manufacturer requirements.
04 · Final Inspection
We inspect the completed system, clean the jobsite and review the finished roof, warranty information and maintenance needs with the owner.
Roof Replacement Systems We Install
Fiberglass Composition Shingles
Architectural, also known as laminated or dimensional shingles are among the highest quality roofing products made. Traditionally they are composed of a heavy fiberglass mat base and ceramic coated mineral granules tightly embedded in carefully refined, water-resistant asphalt.
Luxury/Designer Shingles
Laminated roof shingles designed to provide an enhanced aesthetic improving a building’s curb appeal. The shingle shape and size are modified in a way that simulates the appearance of other, more expensive types, including slate, shake & tile.
Solar Reflective Shingles
Synthetic Slate or Shakes
Synthetic Composite Slate or Shakes are modeled from actual slate or hand-split shakes and made from virgin resins fortified with state -of-the art UV stabilizers for a natural, non-repeating beauty.
Concrete or Clay Tiles
Tile Roof Systems allow you to achieve either an authentic, old world feel or an up-to-date modern look using current technology. The different styles are designed to replicate the customer’s preferred characteristics such as slate, clay and wood.
Cedar Shingles and Shakes
A shake is a basic wooden shingle made from split logs. Higher-grade shakes are typically used for roofing purposes. Properly installed shakes provide long-lasting weather protection. A wood roof system tends to require more maintenance than most other roof surface.
Modified Bitumen Built-up Roof Systems
Modified Bitumen is asphalt that has had modifiers added to it to give it plastic or rubber-like properties. The most common types of modifiers being used are APP (Atactic Polypropylene) and SBS (Styrene Butadiene Styrene). This system is usually mopped, heat applied or self-adhered.
Metal Shingles
PVC Single-Ply Roof Systems
PVC (Polyvinyl Chloride) roof systems are ENERGY STAR qualified and CRRC (Cool Roof Rated Council) certified. They offer the potential for decreased cooling costs and excellent resistance to rooftop chemical attacks including acids, oils and greases.
TPO Single-Ply Roof Systems
TPO (Thermoplastic polyolefin) membranes are ENERGY STAR qualified and CRRC (Cool Roof Rated Council) certified. TPO roof systems have been directly attributed to reducing a building’s energy consumption by greatly diminishing the cost of air conditioning.
Standing Seam Metal Roof Systems
One of the oldest and most practical roofing solutions, Standing Seam Metal Roofing enhances the roofline of virtually any architectural style.
Can a Roof Coating Extend the Existing Roof’s Life?
PROTECTION AND EXTENSION OF ROOF LIFE
In some cases, a properly specified roof coating can protect an existing commercial or low-slope roof and extend its service life without complete replacement. Our team can assess the roof’s condition and determine whether coating, repair or replacement is appropriate. Learn more about our roof repair and maintenance services.
