From engineered commercial projects to large residential installations, we have the experience, the systems, and the attention to detail to install every flat roof correctly the first time.

Flat Roof Systems We Install in Norwalk, CT & Fairfield County

At Melchor Roofing we install two of the most reliable and proven flat roofing systems available for residential and commercial properties across Fairfield County. During your free inspection we assess your property thoroughly and recommend the best system for your specific situation, budget, and long term needs.

GAF Liberty SBS Modified Bitumen System

The GAF Liberty SBS modified bitumen system is one of the most advanced and durable flat roofing systems available today. SBS — or Styrene Butadiene Styrene — is a rubber modifier added to the bitumen that gives the membrane exceptional flexibility, elongation, and resistance to cracking in cold weather. The GAF Liberty system is self-adhering, which eliminates the need for open flame application and significantly reduces installation risk. It is highly resistant to UV exposure, foot traffic, and the extreme temperature swings that Connecticut winters demand. For homeowners and businesses looking for a premium flat roofing solution with outstanding long term performance the GAF Liberty SBS system is our top recommendation.

Benefits of the GAF Liberty SBS System

The GAF Liberty SBS system offers superior flexibility in cold temperatures preventing cracking and splitting that is common with traditional modified bitumen membranes. Its self-adhering design creates a watertight bond across the entire surface with no open flame required. The system carries a strong manufacturer warranty and is backed by GAF's reputation as one of the most trusted roofing manufacturers in North America. Every GAF Liberty installation by Melchor Roofing is backed by our 10-Year Labor Guarantee on top of the manufacturer warranty.

Ideal Applications for GAF Liberty SBS

The GAF Liberty SBS system is ideal for residential flat roof sections, low slope roof areas, porches, dormers, and commercial properties requiring a premium self-adhering membrane system. It performs exceptionally well in Connecticut's climate — standing up to heavy snow loads, ice, and the freeze-thaw cycles that challenge flat roofing systems every winter across Fairfield County.

EPDM Rubber Roofing

EPDM — Ethylene Propylene Diene Monomer — is one of the most widely used and proven flat roofing membranes in the industry. A properly installed EPDM roof can last 25 to 30 years with minimal maintenance, making it one of the most cost-effective long term flat roofing solutions available. Melchor Roofing installs EPDM roofing for residential and commercial properties across Norwalk and Fairfield County using a fully adhered installation method for maximum wind resistance and watertight performance.

Benefits of EPDM Roofing

EPDM is highly resistant to UV exposure, ozone, and extreme temperature fluctuations — making it an excellent choice for Connecticut's climate. It is lightweight, flexible, and maintains its integrity across a wide range of temperatures from extreme cold to intense summer heat. EPDM is also one of the most environmentally friendly roofing materials available and is fully recyclable at the end of its service life. For properties where budget and long term value are the primary considerations EPDM is an outstanding choice.

Ideal Applications for EPDM

EPDM is ideal for large flat or low slope commercial roofs, residential flat roof sections, and properties where a proven low maintenance system is the priority. Its flexibility and durability make it particularly well suited for larger roof areas where seaming and detailing are critical to long term performance.

Our Flat Roof Evaluation Process in Norwalk, CT & Fairfield County

Every flat roof installation starts with a thorough evaluation. Flat roofs have unique drainage, structural, and waterproofing requirements that must be assessed carefully before any system is recommended or installed. Here is exactly how we evaluate every flat roof project across Norwalk and Fairfield County.

Step 1 — Initial Contact & Scheduling

The moment you reach out to Melchor Roofing, Alejandro will call you back personally to discuss your situation and schedule your free flat roof evaluation at a time that is convenient for you. We respond promptly because we know that a failing flat roof can cause serious damage quickly.

Step 2 — Thorough On-Site Evaluation

Our flat roof evaluation covers every critical aspect of your existing roof system. We assess the current membrane condition, check for ponding water areas, evaluate existing drainage including gutters and drains, inspect all penetrations, edges, and termination points, and examine the underlying insulation and deck structure where accessible. We also assess the overall slope and drainage pattern of your roof to identify any areas that may require tapered insulation or additional drainage solutions.

Step 3 — Drainage Assessment

Proper drainage is the most critical factor in flat roof performance and longevity. A flat roof that does not drain correctly will fail prematurely regardless of how good the membrane is. During every evaluation we assess your roof's drainage pattern thoroughly and recommend solutions where needed — including gutter upgrades, additional drains, or tapered insulation systems to eliminate ponding water areas. We have engineered drainage solutions for commercial and large residential flat roof projects across Fairfield County and we bring that expertise to every job we evaluate.

Step 4 — System Recommendation & Detailed Estimate

After our evaluation we recommend the flat roofing system that best suits your property's specific needs, budget, and long term goals. Within 1 to 3 days you will receive a detailed written estimate outlining exactly what we recommend, what materials will be used, and the total cost broken down clearly by line item. We walk you through every detail and answer every question you have — no pressure, no commitment required.

Common Flat Roof Problems We Solve

Tackle these issues early to prevent leaks and water damage, saving you from major costs and ensuring total peace of mind for your home.

01. Ponding water: Standing water strains seals and membranes, eventually finding its way into the building as leaks.

02. Leaks around flashing: Weak or damaged flashing is a common source of leaks because water funnels directly into those gaps.

03. Cracking & blistering: These splits and bubbles create entry points for water to penetrate the membrane and damage the building.

04. Poor previous installation: Improper methods and shortcuts often result in future leaks and early roof failure.

05. Drainage issues: clogged or poorly designed drains trap water on the roof, increasing the risk of leaks and structural damage

Flat Roof FAQs

How long does a flat roof last?

A professionally installed EPDM or SBS flat roof system typically lasts between 20 and 30 years. Regular maintenance and ensuring your drainage systems remain clear are vital to reaching the maximum lifespan of these high-performance materials in our local climate.

What is the best flat roofing material?

We highly recommend EPDM (rubber) for its exceptional durability and GAF Liberty SBS systems for their superior waterproofing. Both are top-tier choices for Connecticut homes, offering long-term protection and resistance to extreme temperature shifts.

How much does a flat roof cost?

The investment for a flat roof is determined by the total square footage, the selected material system, and any necessary plywood repairs. We provide clear, photo-documented estimates so you can see exactly what your project requires for a long-lasting installation.

Can a flat roof be repaired instead of replaced?

Yes, smaller leaks or isolated seam failures can often be repaired to extend your roof's life. However, if the underlying structure is saturated or the material is significantly aged, a full system replacement is usually the safest and most reliable long-term solution.

How do I know if my flat roof is failing?

Warning signs include ponding water that stays on the roof 48 hours after rain, visible blisters or cracks in the membrane, and damp spots on your ceilings. Catching these early through regular inspections prevents extensive water damage to your home's interior.
