Built-Up Roofing vs. Metal Roofing: Which Suits Commercial Properties?

When Austin commercial property owners begin planning a roof upgrade or replacement, one of the most important decisions they face is selecting the right roofing system. While many options exist, two systems continue to stand out for mid-size and large facilities: Built-Up Roofing and metal roofing.

Both systems are widely used across Central Texas commercial properties. Each offers distinct advantages, yet they differ significantly in construction, performance, and long-term expectations. For businesses seeking top commercial roofing in Austin, understanding these differences helps ensure the right investment.

What Makes Built-Up Roofing and Metal Roofing So Different?

Before comparing performance and cost, it helps to understand how each system is built and what it is designed to deliver.

What Is Built-Up Roofing?

Built-Up Roofing, often called tar and gravel, has been used on commercial buildings for decades. The system consists of:

  1. Multiple layers of asphalt
  2. Reinforcing fabrics between layers
  3. A protective surface such as gravel or a reflective cap sheet

This layered approach creates a thick barrier designed to resist water intrusion, sunlight exposure, and routine foot traffic.

What Is Metal Roofing?

Metal roofing systems use interlocking steel or aluminum panels that form a sealed, weather-resistant surface. These panels are treated with protective coatings that resist corrosion and reflect heat.

Metal roofing is commonly chosen for:

  1. Long-term durability
  2. Low maintenance requirements
  3. Strong performance in severe weather
  4. Improved energy efficiency

Both systems are proven, but Austin’s climate plays a major role in determining which one performs better over time.

How Austin’s Weather Affects Each Roofing System

Austin experiences high summer heat, sudden storms, humidity, and occasional hail. Commercial roofs must handle constant exposure to these conditions.

Built-Up Roofing in Austin

BUR performs well under heat due to its layered insulation and surface protection. Benefits include:

  1. Strong resistance to UV exposure
  2. Consistent waterproofing when properly maintained
  3. Added surface protection from gravel or cap sheets

However, BUR systems require careful drainage planning. Standing water, seam deterioration, and surface blistering can occur without regular inspections.

Metal Roofing in Austin

Metal roofing performs exceptionally well in Central Texas weather. It excels in:

  1. Heavy rain and rapid drainage
  2. High winds and sudden storms
  3. Temperature fluctuations
  4. Reflecting solar heat during long summers

While hail may cause cosmetic denting, structural integrity typically remains intact.

Durability and Lifespan Comparison

  1. Built-Up Roofing Lifespan: BUR systems generally last between 15 and 25 years depending on drainage and maintenance. They handle foot traffic well but require consistent monitoring.
  2. Metal Roofing Lifespan: Metal roofing offers one of the longest lifespans in commercial roofing, often exceeding 40 years. It resists cracking, moisture absorption, and surface breakdown.

For long-term performance, metal roofing holds a clear advantage.

Installation Cost and Long-Term Value

Built-Up Roofing Cost

BUR systems are often selected for their lower upfront cost, making them suitable for:

  1. Large flat roofs
  2. Older commercial buildings
  3. Budget-conscious replacement projects

Metal Roofing Cost

Metal roofing requires a higher initial investment but delivers value through:

  1. Fewer repairs
  2. Minimal maintenance
  3. Extended service life

Over time, metal roofing often proves more cost-effective for Austin commercial roofing projects.

Choosing the Right System for Your Austin Property

Built-Up Roofing works best for low-slope roofs where insulation and cost control are priorities. Metal roofing suits facilities focused on durability, energy efficiency, and long-term value.

Both systems perform well when installed correctly. The right choice depends on your building design, budget, and operational goals.
