Flat Roof Replacement

Durable, Energy-Efficient Solutions Built to Last

Flat and low-slope roofs function differently than steep residential roofs — and because of that, they require craftsmanship, precision, and materials tailored to their unique challenges. A flat roof that’s installed the right way will protect your building for decades, guarding it against leaks, heat, UV damage, and the wear-and-tear that accumulates over time. A flat roof installed the wrong way can do the exact opposite.

Whether you own a commercial building, manage a multifamily property, or need to replace a flat roof on your home, the roofing system you choose will play a major role in your property’s durability, energy efficiency, and long-term maintenance costs.

At Roof Artistry, flat roofing is one of our specialties. We work with industry-leading materials from trusted manufacturers like GAF, CertainTeed, DecTec, and Gaco, and we take the time to understand your building’s needs before recommending a solution. Our replacements are clean, precise, and built with longevity in mind — and we install every system with the same level of care we’d expect for our own homes and businesses.

Why Flat Roofs Require Specialized Expertise

Flat roofs aren’t entirely “flat” — they have a subtle slope designed to move water toward drains or gutters. Unlike pitched roofs, where water naturally flows downward, flat roofs hold water longer, face more direct sunlight, and experience more foot traffic from maintenance crews. This means:

• The materials need to be flexible yet durable
• Seams and edges must be sealed perfectly
• Drainage paths must remain clear
• Installation must follow strict specifications

A well-installed flat roof can last decades. A poorly installed one can start failing almost immediately. That’s why choosing a team experienced in flat roof replacement matters — and why we take pride in doing this work the right way, without shortcuts.

Flat Roofing Materials We Offer

Different properties have different needs. Some owners want maximum energy efficiency. Others prioritize durability, foot-traffic resistance, or the ability to restore an existing roof without tearing everything off. We help you weigh the pros and cons of each material and choose the one that aligns best with your goals.

Here’s what we offer:

TPO (Thermoplastic Polyolefin)

Lightweight, reflective, and highly energy-efficient

TPO has become one of the most popular flat roofing materials in the country — and for good reason. It handles heat extremely well, reflects UV rays, and helps lower cooling costs. We typically install GAF EverGuard® 060 White TPO, known for its long-term performance and strong welded seams.

Benefits:

• Excellent reflectivity and energy savings
• Heat-welded seams for superior waterproofing
• Resistant to mold and punctures
• Long lifespan with proper maintenance

Great for commercial buildings, multifamily properties, and homes that want efficiency and durability.

EPDM Rubber Roofing

Flexible in extreme temperatures and built for longevity

EPDM is a synthetic rubber membrane that performs exceptionally well in both hot and cold climates. Its flexibility helps it expand and contract without cracking, making it a reliable choice for properties that experience significant temperature swings.

Benefits:

• Cost-effective
• Durable and low-maintenance
• Excellent for cold or variable climates

EPDM does not offer the same reflectivity as TPO, but it remains one of the longest-lasting flat roofing systems available.

Modified Bitumen

Tough, puncture-resistant, and perfect for foot traffic

Modified bitumen is a multi-layered, asphalt-based material designed to withstand heavy use. If your roof sees frequent foot traffic — HVAC technicians, maintenance crews, or building staff — this may be the ideal choice.

We install systems such as GAF Liberty® and CertainTeed Flintlastic, two of the most trusted names in the industry.

Benefits:

• Highly puncture-resistant
• Great for walkable surfaces
• Durable in a wide range of climates

A strong, reliable system with predictable performance.

DecTec® Waterproof Membranes

A stylish, waterproof surface ideal for rooftop decks

DecTec is different from traditional roofing membranes. It’s waterproof, slip-resistant, and designed to be seen. That makes it perfect for:

• Rooftop decks
• Balconies
• Walkways
• Patio roofs

If you want a flat roof that doubles as a usable outdoor space, DecTec offers both performance and beauty.

Gaco Roof Coating (Silicone Coating System)

A restoration solution that extends the life of an existing roof

If your flat roof is worn but structurally sound, a silicone coating may be the most cost-effective solution. Gaco’s silicone roof coatings create a seamless, waterproof barrier that reflects sunlight and prevents future leaks.

Benefits:

• Extends roof life 10–20 years
• Creates a monolithic waterproof surface
• Excellent UV protection
• No seams, no fasteners

Best for restoring — not replacing — a roof that still has structural integrity.

Signs It’s Time to Replace Your Flat Roof

You don’t need to wait for a major leak to know something’s wrong. Flat roofs often show subtle warning signs first:

• Frequent leaks or water pooling
• Cracks, blisters, or punctures in the membrane
• Separation at seams or flashing
• Soft spots from moisture infiltration
• Major discoloration or UV damage
• Rising energy bills
• The roof is at or beyond its expected service life

If you’ve noticed one or more of these issues, a professional inspection can help you determine whether a repair, restoration, or full replacement is the most cost-effective path forward.

Our Flat Roof Replacement Process

We’ve refined our process to be thorough, efficient, and transparent. You’ll know exactly what’s happening at every stage of the project.

1. Detailed Roof Assessment

Our team inspects your entire roofing system, including:

• Membrane condition
• Flashings
• Drainage points
• Underlayment and insulation
• Penetrations (vents, HVAC, piping)

We identify not just the visible issues but any hidden concerns that could affect your new roof.

2. Material Selection

We walk you through the best roofing systems for your building’s needs and budget. You’ll get clear explanations — not confusing jargon — and honest recommendations.

3. Tear-Off & Surface Preparation

We remove old materials, repair the substrate, and prepare the surface so your new roof bonds securely.

4. High-Quality Installation

Every step is completed according to manufacturer guidelines. This is critical because it protects your warranty and ensures maximum lifespan.

5. Seam & Edge Sealing

We reinforce all seams, penetrations, and flashing points — the areas where leaks most commonly start.

6. Final Inspection

Nothing is considered complete until we’ve checked every detail for accuracy, durability, and weather readiness.

FAQ: Flat Roof Replacement

How long does a flat roof replacement take?

Most projects take 1–3 days depending on size, material, and weather conditions. Large commercial roofs may take longer, but we always aim to minimize disruption.

Do I need a full replacement or just a coating?

If your roof is structurally sound with only surface wear, a coating may be a great option. If it has widespread leaks, membrane failure, or saturated insulation, a replacement is usually more cost-effective.

What is the most durable flat roofing material?

TPO and EPDM both offer excellent longevity. Modified bitumen is extremely durable with foot traffic. The right choice depends on your building’s needs.

Will a new flat roof improve energy efficiency?

Yes. Modern membranes — especially white TPO — can significantly reduce heat absorption, leading to lower cooling costs.

What maintenance does a flat roof require?

We recommend twice-yearly inspections and simple upkeep like clearing drains. Proper maintenance dramatically extends the roof’s lifespan.
