Commercial Roof Replacement: Full Tear-Off and Deck Preparation
Complete removal of the existing roofing assembly involves the use of industrial roof cutters and high-volume vacuum trucks to clear debris. This process exposes the underlying structural deck for a comprehensive inspection of wood rot or metal corrosion. Ensuring a clean, dry substrate is critical for the long-term adhesion of the new roofing system.
Structural deck repairs utilize CDX plywood or heavy-gauge steel fluting to restore the load-bearing capacity of the roof. New substrate boards are mechanically fastened using specialized drill-point screws to meet current building code requirements. This phase eliminates hidden moisture traps that could lead to premature failure of the replacement membrane.
Advanced vapor barriers are installed over the prepared deck to prevent internal building moisture from migrating into the insulation. These self-adhering membranes create an airtight seal that improves the overall thermal efficiency of the structure. Proper deck preparation ensures the new roof system performs to its maximum design life.
Commercial Roof Replacement: Tapered Insulation Systems
Custom-designed tapered polyisocyanurate insulation systems are engineered to create a positive slope on flat roof surfaces. These boards are cut to specific gradients using computerized hot-wire tools to ensure precise water flow toward drains and scuppers. Eliminating ponding water is essential for maintaining the manufacturer's warranty on the replacement membrane.
The installation utilizes low-rise polyurethane foam adhesives to secure the insulation layers without penetrating the structural deck. This method provides a continuous thermal break and eliminates thermal bridging caused by metal fasteners. Staggered joint patterns are strictly followed to prevent air gaps and ensure a rigid, stable surface.
Drain sumps are professionally fabricated by thinning the insulation around internal outlets to accelerate water evacuation. This engineering prevents excessive weight loads from accumulating on the roof during heavy Irvine rainstorms. The resulting slope-to-drain configuration significantly extends the functional lifespan of the entire roofing assembly.
Commercial Roof Replacement: Modified Bitumen Overlays
Modified bitumen replacement involves the application of APP or SBS granulated cap sheets over a reinforced base ply. High-output propane torches or cold-applied adhesives are used to fuse the layers into a multi-ply waterproofing system. This redundant approach provides multiple layers of protection against punctures and mechanical damage.
Granulated surfaces offer superior UV protection and are available in various colors to match the building's aesthetic requirements. The dual-layer construction provides exceptional dimensional stability and resistance to thermal shock. This system is ideal for roofs with high foot traffic or those housing extensive mechanical equipment.
Reinforced transition strips are applied at all vertical-to-horizontal junctions to accommodate structural movement. Heavy-duty metal counter-flashings are reglet-mounted into masonry walls to provide a permanent, watertight seal. The finished replacement offers a robust, traditional roofing solution with modernized material technology.
Commercial Roof Replacement: PVC Retrofit Systems
PVC retrofit solutions allow for the installation of a new high-performance membrane directly over an existing functional roof. A specialized separator sheet or flute-fill insulation is used to prevent chemical incompatibility between the old and new materials. This method reduces construction waste and avoids the operational downtime associated with a full tear-off.
The new PVC membrane is secured using the RhinoBond induction welding system for a non-penetrating, high-wind-rated attachment. This technology bonds the membrane to the plates beneath it, creating a secure and uniform grid of attachment points. Heat-welded seams ensure the retrofit system is as durable and watertight as a completely new installation.
New edge metal and coping caps are installed to provide a fresh architectural appearance and enhanced wind protection. All existing penetrations are re-flashed with new PVC accessories to ensure a seamless transition between old and new components. This cost-effective replacement strategy provides a 20-year warranted solution with minimal environmental impact.

Systematic Tear-Off and Structural Deck Remediation
We utilize specialized roof stripping machines to efficiently remove existing gravel, membranes, and saturated insulation layers. Debris is transported directly from the roof to sealed containers via heavy-duty trash chutes to maintain a clean job site. This controlled removal process prevents the accumulation of weight on the structure during the replacement phase.
Once the deck is exposed, technicians perform a comprehensive visual and physical audit of the structural material. Damaged sections of corrugated steel or rotted wood decking are removed and replaced with identical gauge materials. This remediation ensures that the new roofing system is installed over a sound and reliable foundation.
The exposed deck is treated with antimicrobial solutions to neutralize any existing mold or fungal spores. Industrial blowers are used to ensure the surface is completely dry before the new assembly is applied. This thorough cleaning process prevents the entrapment of contaminants between the old structure and the new roof.
High-Performance Underlayment and Base Sheet Application
A heavy-duty SBS-modified bitumen base sheet is installed over the remediated deck to provide an initial layer of protection. This sheet is either mechanically fastened or hot-mopped depending on the specific engineering requirements of the building. The base layer serves as a secondary moisture barrier and a stable platform for the final surfacing.
We utilize propane torches to carefully fuse the laps of the base sheet, creating a continuous watertight seal. This "torch-down" method requires extreme precision and constant fire-watch monitoring to ensure safety and quality. The resulting bond is impervious to water and provides exceptional dimensional stability for the entire system.
For projects requiring enhanced fire resistance, specialized gypsum cover boards are installed over the base layer. These boards are secured with low-rise adhesive foam to provide a smooth and impact-resistant surface. This additional layer protects the insulation from foot traffic and improves the overall fire rating of the commercial structure.
Multi-Layer Bitumen or Single-Ply Overlayment
The primary waterproofing layer consists of a high-grade granulated cap sheet or a thick single-ply membrane. This material is rolled out with precise overlaps to ensure that all seams are properly offset from the underlying layers. The selection of the cap sheet is based on the specific environmental stressors present at the Irvine location.
Advanced cold-applied adhesives are used in areas where open flames are restricted or undesirable for the facility. These adhesives provide a high-strength bond while remaining flexible enough to accommodate the natural expansion of the building. This method ensures a quiet and low-odor installation process for occupied commercial spaces.
Our roofers use weighted rollers to press the membrane into the adhesive, ensuring 100% surface contact and eliminating voids. This step is critical for preventing the formation of blisters or bubbles that can compromise the roof's integrity. The resulting multi-layer system provides redundant protection against leaks and physical damage.
Final System Calibration and Drainage Optimization
Retrofit roof drains with heavy-duty cast iron strainers are installed to replace aging or damaged drainage hardware. These units are integrated into the new membrane using reinforced flashing details to prevent leaks at the drain sumps. Proper drainage is verified by conducting a controlled water flow test across the entire roof expanse.
New overflow scuppers are cut into the parapet walls to provide a secondary exit for water during extreme rain events. These scuppers are lined with custom-fabricated stainless steel sleeves and sealed with high-performance membranes. This safety feature prevents water from accumulating to dangerous levels if the primary drains become obstructed.
A final application of reflective silver coating or white granules is applied to the seams and flashings for UV protection. This coating reflects solar energy and prevents the localized overheating of the membrane at the joints. The project concludes with a comprehensive cleanup and the removal of all specialized equipment from the site.
