What is a Built-Up Roof (BUR)?

We often hear the term “Built-Up Roof” but what does it really mean? Simply put, a Built-Up Roof (BUR) is a roofing system made by layering multiple materials like asphalt and felts to create a thick, durable barrier. Think of it like a layered cake each layer builds strength and protection. It’s one of the oldest and most trusted roofing styles, especially for flat or low-slope roofs like many you see across NYC.

Why NYC Property Owners Trust Built-Up Roofing

You and I both know how unpredictable New York weather can be. One day it’s a harsh winter storm, the next it’s the blazing summer sun. That’s why so many NYC property owners turn to BUR. It’s proven to withstand heavy rain, snow, and temperature swings better than many modern roofing materials. When you choose BUR, you’re choosing a roof that can take the punches and keep your building safe.

A Quick History of BUR

Built-Up Roofing has been around since the late 1800s. Over the decades, it’s evolved but stayed true to its core promise: long-lasting protection. It was first popularized in commercial buildings, and it quickly became a staple for NYC’s flat roofs because of how well it handles the city’s weather extremes and heavy foot traffic.

How a Built-Up Roof is Made

The Layers That Matter

We build a BUR with multiple layers stacked carefully:

• Base Sheet: This is the first layer over your roof deck or insulation.
• Ply Sheets: These are felts soaked in bitumen (tar or asphalt).
• Bitumen Layers: Applied hot or cold, this sticky substance seals and waterproofs each ply.
• Surfacing: The top layer usually gravel or mineral granules that protects the layers beneath from UV rays and weather.

Each layer adds strength and makes sure water stays out.

Materials Used in BUR Systems

Typically, we use organic or fiberglass felts, asphalt or coal tar, and gravel or other ballast materials. These materials work together to form a heavy-duty shield that resists damage from sun, water, and wear.

Types of Built-Up Roofing Systems

Asphalt BUR

This is the most common type you’ll find in NYC. Asphalt is heated and applied with felts, creating a reliable, waterproof surface.

Coal Tar BUR

Coal tar systems resist chemicals better and heal minor cracks over time, but they tend to be more expensive and harder to work with.

Cold BUR

For when hot asphalt isn’t safe or practical, cold adhesives replace heat. It’s safer for workers and buildings but requires precise application.

Benefits of Built-Up Roofs in NYC

Durability Against Harsh Weather

We all know how tough NYC weather can get. BUR is designed to handle snow, rain, and heat without cracking or leaking. Its multiple layers act like armor, giving you confidence that your roof won’t give out when you need it most.

Waterproofing Like No Other

Every layer adds a waterproof barrier. When water tries to sneak in, the BUR pushes it away. This is especially important in NYC, where freeze-thaw cycles can cause other roofs to crack.

Fire Resistance for Safety

The gravel or mineral surface helps protect against fire. That’s peace of mind, especially when your building is surrounded by others.

Energy Savings Over Time

Because BUR adds insulation mass, it helps keep your building cooler in summer and warmer in winter. You’ll notice the difference on your energy bills.

Challenges of Built-Up Roofing

Installation Time

We won’t sugarcoat it it takes time to install a quality BUR. You can’t rush the layering process, and that means some patience is required.

Weight Concerns

BUR is heavy. If your building isn’t built to hold the extra weight, you may need structural reinforcement before installation.

BUR vs. Modern Roofing Alternatives

You might have heard about TPO or EPDM roofing. They’re lightweight and quick to install, but in NYC’s extreme weather, BUR’s thick, layered system often lasts longer and needs fewer repairs.

Is BUR Right for Your NYC Property?

If your building has a flat or low-slope roof and you want a roof that can last decades with proper care, BUR is a strong candidate. It’s especially great for commercial buildings, schools, and multi-family residences.

Maintenance Tips for Long Life

• Schedule inspections twice a year
• Quickly remove debris and leaves
• Keep drains clear so water doesn’t pool
• Reapply surface coatings every 5 to 10 years

If you and we work together to care for your BUR, it will reward you with years of solid performance.

Signs Your BUR Needs Repair

• Bubbling or blisters on the roof surface
• Areas where gravel has worn away
• Water stains inside your building
• Pools of water that don’t drain properly

Spotting these early means we can fix issues before they become costly disasters.
