Trusted Commercial Roofing for Local Businesses

When your building is dealing with leaks, standing water, or sections that keep needing repairs, the priority is identifying and addressing the issue before it affects operations inside. At that point, you need more than a quick fix. You need a clear plan for whether the roof can be repaired or if a full roof replacement makes more sense.

Seci Construction Inc. is a licensed and insured roofing company with experience working on active commercial properties across New Jersey, New York, Pennsylvania, and Connecticut. We offer comprehensive solutions for coordination, permits, and project staging so work can move forward without unnecessary delays or disruptions.

As a GAF Certified Contractor, we install manufacturer-approved systems that meet required specifications for performance and warranty eligibility. This allows us to offer extended warranty options that help protect your property long after our work is complete. With a commitment to quality workmanship, we are a trusted contractor for all your commercial roofing needs.

Commercial Roofing Systems Installed by Seci Construction, Inc

Most professional roof installations for commercial buildings rely on flat or low-slope roofing, where drainage, seams, and surface wear play a major role in long-term performance. Our commercial roofing contractors provide roof maintenance, repairs, and replacements designed around how your building handles water, foot traffic, and weather exposure over time.

EPDM Roofing

This rubber membrane flat roofing system works where movement and temperature shifts are constant. We reinforce seams, flashing, and perimeter edges to help prevent separation, shrinkage, and long-term leak points.

Torch Down Roofing

Torch down roofing when heat is used for application. It is an asphalt-based system designed for durability, flexibility, and low-slope commercial use.

Low-Slope Roofing

GAF Liberty is used on smaller low-slope sections where open flame is not practical. We apply it with proper adhesion and edge detailing to support warranty coverage and consistent long-term performance.

Metal Roofing

Metal roofing is used on industrial buildings and warehouses where durability is critical. We align panels and secure fasteners properly to limit movement, reduce wear, and prevent future leak issues.

24 Months 0% Financing Available

SECI Construction, Inc is proud to offer financing options for our customers.

Commercial Roof Replacement

A full roof replacement becomes necessary when the existing system is no longer performing consistently. If issues continue to show up across multiple areas or repairs are no longer holding, it is usually more practical to install a new roof.

We start all commercial roofing projects with a detailed roof inspection to evaluate the surface, insulation, and decking materials. On many commercial buildings, moisture can spread beneath the system before becoming visible inside.

Signs that a full commercial roof replacement may be needed include:

Recurring leaks in similar areas
Surface separation or visible wear
Standing water that does not drain
Soft or weakened sections beneath the membrane

Commercial Roof Repair

Commercial roof repairs are often the right approach when issues are limited and the rest of the system remains stable. Our focus is on identifying the source of the problem rather than just addressing surface damage.

Our repairs for commercial buildings with flat roofing systems usually include:

Leak detection across large roof areas
Seam reinforcement for EPDM, PVC, and Torch Down Roofing systems
Flashing adjustments around rooftop units and edges
Storm damage repairs
Drainage corrections to improve water flow

Warranty Coverage for Commercial Roof Projects

Warranty coverage on a commercial roof is tied directly to how the system is installed, not just the materials used. That is why working with the right commercial roofing company that has the relevant certification, documentation, and inspection standards plays a major role in what coverage you actually receive.

Seci Construction Inc. is a GAF Certified Roofing Company

As a GAF Certified Commercial Contractor with President’s Club and Master Elite status, our work must meet strict manufacturer guidelines. This includes approved materials, verified installation methods, and proper documentation. These requirements allow access to GAF warranty programs that are not available through other roofing companies with non-certified contractors

GAF System Pledge and Integrated System Warranties

For qualifying systems such as GAF Liberty low-slope roofing, we can offer System Pledge and Integrated System warranties. These warranties are designed to cover full system performance when installed to specification. That can include membrane integrity, seams, attachment points, and eligible workmanship coverage tied to the system.

Vadim S

SECI Construction Inc. just completed roof and gutters installation on my property. First of all - the estimation process done by Edi was smooth and painless, differences between different roofing materials clearly explained. I have collected a few estimates and the one provided by Edi was fair enough - needless to say that the other guy tried to charge me twice more for the same materials and job. The work has been scheduled on one day after signing proposal. Project manager Lagys organized the work of 10 people crew very efficiently and the whole job has been completed on the second day. Lagys took time to show me all the details of the finished work and made sure all has been done to my satisfaction. The property has been carefully cleaned up and all the garage left from the old roof has been removed. Nice job - five stars! Iwill definitely work with Seci Construction Inc. for my future projects.

DILIA P.

We had an emergency situation when our roof was being replaced—the condition turned out to be much worse than expected, with rotten rafters and wood that all needed to be replaced. With rain expected the very next day, the company immediately took control and handled the situation without hesitation.In a time where many contractors don’t show up or don’t follow through on what they promise, this company was the complete opposite. They showed up when they said they would and got the job done right.One of the owners, Achilles, personally came to explain everything clearly to me and my husband. He made promises—and more importantly, he delivered on every single one. I have honestly never seen such a fast and professional response from any contractor.Achilles is a wonderful person, and his leadership truly showed during this stressful situation. The entire crew worked incredibly hard and were always respectful and professional.What impressed me the most was how they handled the emergency. On the very first day, they made sure our home was secure and safe, which gave us real peace of mind.I highly recommend this company to anyone looking for reliable, honest, and responsive roofing professionals.

Response from the owner: Thank you so much or your heartfelt review and for trusting us during such a stressful emergency! We're incredibly grateful that our team stepped up quickly to handle the situation, especially with rain on the way.A special thank you to Achilles for personally explaining everything and delivering on every promise-- its feedback like this that motivates us to keep going the extra mile. We truly appreciate your kind words and are thrilled everything turned out right. Best regards, The Seci Construction Team

Kenneth B.

Although I’ve already written a superb review of SECI, I think a follow up is in order, having lived with the roof they rebuilt in the summer of 2024. We have an antique house, with an 18th century foundation that was rebuilt in 1880, and then added on and updated in the 1960’s. What we thought was going to be a change of asphalt shingles turned out to be a major overhaul as the previous roofer had not removed the original wood shingles and they and the rafters underneath had rotted and also ruined the insulation. So essentially SECI rebuilt the roof, removing all rotten materials, installing good and new insulation, and making sister rafters (doubling) for the old ones, as well as new premium GAF TImberline HDz asphalt shingles. We also replaced 11 Skylights.Over the almost 18 months since completion, we have had a much more silent, solid house. Cooler in the hottest days of summer, and cozy and warm today in the coldest day in years. We had assumed that “this old house” was subject to drafts and exterior noise. WRONG! SECI has changed not just the exterior appearance of our house for the better but also markedly improved the quality of our lives. I might add that all their workmen were courteous, polite, respectful, and took care for us to have the least inconvenience during a major construction project. The manager Cobra and construction supervisor Manny were always courteous at our beck and call-and have remained so for any questions.

Response from the owner: Hi Kenneth, Thank you for the wonderful review and all the kind words. We appreciate your business and for allowing us to work on your beautiful home. I will Relay the message to the team! Thanks- Seci Construction, Inc.
