By employing industrial-grade sealants, reinforced patching, advanced infrared leak detection, and state-of-the-art waterproofing techniques, our team restores your roof's integrity, preventing costly structural issues and extending the lifespan of the system.
Flat & Low-Slope Roofing
Designed specifically for large commercial and industrial buildings, our flat and low-slope roofing systems combine efficient drainage with exceptional waterproofing capabilities. We install advanced single-ply membranes like TPO and EPDM, as well as modified bitumen systems, all engineered for durability, energy efficiency, and low maintenance requirements.
Metal Roofing
Our commercial metal roofing systems provide exceptional durability, energy efficiency, and weather resistance, ensuring lasting protection for your building. Made from interlocking panels crafted from galvanized steel, aluminum, or copper, each installation forms a continuous, watertight barrier that withstands corrosion, high winds, and fire. Sturdy commercial metal roofs guarantee decades of low-maintenance protection for our business clients.
Sloped / Steep-Slope Roofing
Ideal for properties featuring roof pitches of 3:12 or steeper, our steep-slope roofing combines architectural sophistication with excellent water drainage performance. We use high-quality materials such as asphalt shingles, clay or concrete tiles, and natural slate to ensure stunning aesthetics, exceptional structural strength, and reduced maintenance costs.
Commercial Roof Sealing
Our roof sealing service extends the life of your existing roof by applying a liquid protective coating that prevents leaks and enhances reflectivity. By using acrylic, silicone, or polyurethane coatings, we create a continuous waterproof membrane that protects against UV rays, standing water, and thermal stress—guaranteeing that your operations go on without interruption.
Commercial Reflective Roofing Installation
Lower your building's cooling costs with our cutting-edge cool roof systems, designed to reflect as much as 80–90% of sunlight and lower roof surface temperatures by up to 50°F. We utilize white membranes, reflective coatings, and cool-toned shingles to boost energy efficiency and improve indoor comfort year-round.
Commercial Roof Inspection & Assessment
Our comprehensive roof inspections identify potential problems early through a meticulous 9-step evaluation process, which encompasses drainage assessments, flashing inspections, and optional thermal imaging. You will receive a detailed report featuring actionable recommendations, helping to prevent costly repairs and extend the lifespan of your roof.

What Types of Material Do We Use for Commercial Roofs?
TPO, EPDM, PVC Roofing
Lower your building's cooling costs with our state-of-the-art cool roof systems, engineered to reflect between 80–90% of sunlight while decreasing roof surface temperatures by as much as 50°F. We offer services that include the installation of white membranes, reflective coatings, and cool-colored shingles to boost energy efficiency and improve interior comfort year-round.

You'll receive an all-encompassing report featuring actionable recommendations, helping to prevent costly repairs and prolonging the lifespan of your roof.

We provide thorough roof maintenance designed to prevent leaks, prolong system lifespan, and enhance performance through routine inspections, cleaning, and minor repairs. Our evaluations, debris removal, seam resealing, and drainage assessments assist property owners in avoiding expensive downtime, safeguarding warranties, and ensuring continuous waterproofing for all commercial roofing systems.
Metal Roofing
Metal roofing offers a lifespan of 40 to 60 years and has the ability to reflect up to 70% of solar heat, making it one of the most energy-efficient and sustainable options for commercial use. With impressive wind resistance of up to 140 mph, these roofs also bring a sleek, modern aesthetic that elevates the appearance of commercial structures.
Flat and Low-Slope Roofing Systems
Flat and low-slope roofs are engineered for superior drainage and waterproof performance, significantly reducing the risk of leaks and water accumulation. Our flat and low-slope roofs feature high-R-value insulation and seamless membranes, guaranteeing energy efficiency all year round.
What Types of Material Do We Use for Commercial Roofs?
Ponding Water
Ponding water occurs when insufficient drainage or inconsistent insulation results in water buildup on flat or low-slope roofs, accelerating membrane deterioration and the development of leaks. We tackle this problem by regrading the surface with tapered insulation, clearing any blockages in the drains, and applying waterproof coatings to guarantee proper runoff and avert future pooling.
Flashing Failure
Poorly installed flashing around vents, HVAC units, or edges often leads to water intrusion and interior leaks. We meticulously remove compromised flashing, reseal or replace it with high-quality metal or TPO-compatible materials, and strengthen seams to ensure enduring waterproof protection.
Damaged Roofing Membrane
Over time, roof membranes may suffer from cracking, blistering, or puncturing due to various factors including UV exposure, foot traffic, and fluctuations in temperature. Our team employs thorough patching, seam resealing, and infrared moisture scanning to identify weak spots and reinstate a watertight barrier, all without the need for a full replacement.
Storm or Tree Impact Damage
Intense winds, broken branches, and storm debris can cause punctures, ripped membranes, and serious roof damage. Our specialists conduct emergency assessments, remove debris, reinforce affected areas, and perform thorough membrane restoration or panel replacement to bring your roof back to its original condition.
How Much Does Commercial Roof Replacement Cost?
The cost of repairing a commercial flat roof in Paramount typically ranges from $6 to $18 per square foot, fluctuating based on the roofing system, building size, and complexity. TPO, EPDM, and PVC roofs generally average between $7 and $15 per square foot, while Built-Up (BUR), Modified Bitumen, and Metal systems can increase to $16 to $22 per square foot for premium materials and multilayer protection. In an average commercial roof replacement project, materials account for about 40 to 50% of total costs, with labor making up 30 to 40%. Various factors, such as roof accessibility, necessary tear-offs, and local regulations, can impact pricing.
Typical Cost Range Per Square Foot:
| Roofing Type | Typical Cost Range (per sq ft) |
|---|---|
| Single-Ply TPO | $7.00 – $15.00 |
| EPDM (rubber membrane) | $6.00 – $14.00 |
| Single-Ply PVC | $8.00 – $15.00 |
| Modified Bitumen | $9.50 – $16.00 |
| Built-Up Roofing (BUR) | $10.00 – $22.00 |

| Labor & Installation | ~30-40% | Skilled labor, seam welding, substrate preparation, safety measures, cleanup. |
| Tear-off / Disposal & Substrate Repair | ~10-20% | Removal of old roof, disposal fees, repair/replacement of damaged deck or insulation. |

How Long Does a Commercial Roof Replacement Take?
A standard roof replacement project typically takes anywhere from five days to four weeks, depending on factors such as the size of the roof, the materials used, and the intricacy of the project. Single-ply systems, including TPO, PVC, and EPDM, are generally quicker to install, often completed within one to two weeks. On the other hand, multi-layer systems like BUR, modified bitumen, or metal roofing usually necessitate a longer duration due to the complexities inherent in their installation.
Cost Breakdown:
| Project Phase | Timeline | Scope of Work |
|---|---|---|
| Roof Inspection & Assessment | 1-3 days | Our team inspects the existing roof, identifies damage, and evaluates substrate and drainage conditions. |
| Final Quotation & Project Planning | 2-5 days | We provide a detailed estimate and help you choose the best system—TPO, PVC, EPDM, BUR, or metal—based on performance and budget. |
| Pre-Work & Project Scheduling | 3 to 7 days | We handle local permits, compliance checks, and coordinate logistics to minimize disruption to your operations. |
| Roof Tear-Off & Surface Preparation | 2 to 7 days | Old roofing materials are safely removed, and the substrate is repaired or reinforced for new installation. |
| Roof Installation & Seaming | 5 to 14 days | Depending on the roof type and size (e.g., TPO and EPDM install faster than BUR or metal), our crew installs the new system with precision sealing and insulation. |
| Final Inspection & Site Cleanup | 1 to 2 days | We'll do a quality check, water-test the roof, and leave your property clean and business-ready. |
