What is Built Up Roofing? A Complete Guide for Pennsylvania Business Owners: Table of Contents
If you’re a business owner in Pennsylvania considering roofing options for your commercial property, you’ve likely encountered the term “built-up roofing” or BUR. But what is built-up roofing? Built-up roofing is a traditional multi-layer roofing system that has protected commercial buildings for over a century, consisting of alternating layers of bitumen and reinforcing materials that create a durable, waterproof barrier.
Understanding Built-Up Roofing Systems
Built-up roofing systems, commonly known as BUR systems, are constructed using multiple layers of different materials applied directly to the roof deck. This time-tested approach creates a reliable roof through the application of alternating layers of asphalt or coal tar and reinforcing ply sheets. The process begins with a base sheet adhered to the roof deck, followed by layers of bitumen and additional reinforcing materials.
The main advantage of BUR roofs lies in their proven longevity and excellent protection against weather conditions. Commercial property owners have relied on these systems for decades because they offer:
- Exceptional durability: Multiple layers provide redundancy against water damage
- Cost-effectiveness: Lower square foot installation costs compared to some modern systems
- Proven performance: Decades of experience demonstrate reliability in various climates
- Foot traffic resistance: The robust construction handles regular maintenance activities
How BUR Compares to Other Commercial Roofing Options
When evaluating roofing options for commercial buildings, it’s essential to understand how built-up roofing systems compare to other roofing types. Single-ply membranes like TPO and EPDM (ethylene propylene diene monomer) offer ease of installation and energy efficiency benefits, while metal roofs provide excellent longevity and aesthetic appeal.
However, BUR systems offer unique advantages for specific needs. Unlike single-ply systems that rely on seam integrity, built-up roofing creates a monolithic surface with no vulnerable seams. This makes it an excellent choice for low-slope roofs and flat roofs where water pooling might be a concern.
Installation Process and Materials
The installation of a built-up roofing system requires proper installation techniques and adherence to local building codes. Professional roofing companies begin by preparing the roof deck and applying the base sheet. Hot asphalt or asphalt cement is then applied, followed by reinforcing felt or fabric layers. This process repeats until the desired number of layers is achieved.
The materials used in BUR systems include:
- Bitumen: Either asphalt or coal tar provides waterproofing
- Reinforcing materials: Felt, fabric, or fiberglass strengthen the system
- Surfacing materials: Gravel, mineral granules, or reflective coating protect against UV rays
- Insulation: Often installed beneath the system for energy efficiency
Energy Efficiency and Environmental Considerations
Modern built-up roofing systems can incorporate energy-efficient features to reduce energy costs. A reflective coating applied to the surface helps deflect UV radiation and reduce cooling demands. This approach can significantly impact energy savings while maintaining the proven reliability of traditional BUR construction.
Building owners should also consider the environmental impact of their roofing choice. Built-up roofing systems can be designed with recyclable materials and proper maintenance can extend their lifespan, reducing long-term environmental impact compared to roofs requiring frequent replacement.
Maintenance Requirements and Longevity
The longevity of your roof depends heavily on regular maintenance and proper installation. BUR systems typically require regular inspections to identify potential issues before they become costly repairs. The low maintenance requirements of these systems make them attractive to commercial property owners who want reliable protection without constant attention.
A general guideline for BUR maintenance includes:
- Annual inspections: Professional assessment of system condition
- Prompt repairs: Addressing minor issues before they expand
- Drainage maintenance: Ensuring proper water flow off flat surfaces
- Surface protection: Reapplying protective coatings as needed
Is Built-Up Roofing the Right Choice for Your Business?
Determining the best roofing materials for your commercial property depends on various factors, including budget, building design, and specific needs. Built-up roofing systems remain a popular choice for many commercial properties because they offer excellent protection at competitive labor costs.
This roofing solution works particularly well for:
- Historic buildings: Where traditional materials and methods are preferred
- Large commercial properties: Where cost per square foot is a primary concern
- Buildings with heavy foot traffic: Where durability is essential
- Properties requiring long-term reliability: Where proven performance matters
