Commercial roofing is essential for maintaining the integrity and functionality of any business establishment. At MHI Roofing, we understand that business owners have many questions about commercial roofs. This blog aims to address the most frequently asked questions and provide you with the information you need to make informed decisions about your commercial roofing needs.
What Types of Commercial Roofing Systems Are Available?
Selecting the appropriate commercial roofing system involves considering factors like the roof’s purpose, architectural style, and local climate. Here are common types of commercial roofing, each with unique benefits:
- Single-Ply Membranes: Durable, lightweight, and resistant to tears and leaks.
- Modified Bitumen: Reinforced asphalt membrane, ideal for flat or low-slope roofs, installed in two layers.
- PVC (Polyvinyl Chloride): Single-ply, suitable for flat or low-slope roofs.
- Asphalt Shingles: Affordable and lightweight, with a fiberglass or organic base coated in asphalt and mineral granules.
- Metal Roofing: Long-lasting (40-60 years), available in materials like aluminum, copper, tin, zinc, and stainless steel.
- TPO (Thermoplastic Olefin): Known for durability and energy efficiency, reducing energy costs.
- EPDM (Ethylene Propylene Diene Monomer): Synthetic rubber is known for longevity and weather resistance.
How Long Does a Commercial Roof Last?
When selecting a commercial roofing system, understanding its expected lifespan is crucial. Here are the typical lifespans of various commercial roofing materials:
- Single-Ply Membranes: 20-30 years
- Modified Bitumen: 15-20 years
- PVC (Polyvinyl Chloride): 20-30 years
- Asphalt Shingles: 15-30 years
- Metal Roofing: 40-60 years
- TPO (Thermoplastic Olefin): 20-30 years
- EPDM (Ethylene Propylene Diene Monomer): 20-30 years
Regular maintenance and timely repairs can significantly extend the lifespan of your commercial roof.
What Are the Signs That My Commercial Roof Needs Repair?
Identifying issues early can prevent costly damage. Here are common signs that your commercial roof may need repair:
- Leaks and Water Damage: Water stains on ceilings or walls often indicate roof leaks.
- Ponding of Water: Water that remains on the roof for more than 48 hrs often indicates sagging areas and areas for potential leaks and water damage.
- Blistering or Bubbling: These are signs of trapped moisture within the roofing layers.
- Sagging Areas: Any sagging or uneven spots on the roof surface should be inspected immediately.
- Visible Damage: Cracks, tears, or punctures in the roofing material can lead to significant issues if not addressed promptly.
- Mold or Mildew Growth: Mold and mildew growth on a commercial roof often indicates persistent moisture issues and can indicate underlying water damage. These fungi not only damage roofing materials but can also pose health risks to building occupants.
- Increased Energy Bills: High energy costs may indicate that your roof is not maintaining proper temperature regulation due to issues like leaks or insufficient insulation.
How Do Flat Roofs Drain Water?
Flat roofs, despite their name, are not entirely flat. They have a slight slope to facilitate drainage. Here are the primary methods used to drain water from flat roofs:
- Internal Drains: Internal drains are positioned strategically around the roof to collect water and direct it through a system of pipes inside the building, preventing water accumulation and leaks.
- Scuppers: Scuppers are openings placed at the edge of the roof that allow water to drain off the roof and into downspouts or directly off the building.
- Gutters: Gutters along the perimeter of the roof catch and direct water away from the building foundation, protecting the structure from water damage.
How Often Should I Schedule Commercial Roof Inspections?
Regular inspections are important to maintaining the health of your commercial roof. We recommend scheduling inspections at least twice a year—preferably in the spring and fall. Additionally, it’s wise to have your roof inspected after any severe weather events, such as heavy storms or hail.
What Is the Best Way to Maintain a Commercial Roof?
Proper maintenance involves several key practices:
- Regular Cleaning: Keep your roof free from debris, leaves, and other materials that can trap moisture.
- Gutter Maintenance: Ensure that gutters and downspouts are clear and functioning correctly to prevent water buildup.
- Timely Repairs: Address any minor issues immediately to prevent them from escalating into major problems.
- Professional Inspections: Hire professional commercial roofers for regular inspections and maintenance.
How Much Does Commercial Roofing Cost?
The cost of a commercial roofing project can vary widely based on factors such as the size of the roof, the type of materials used, and the complexity of the installation. Here are the estimated costs per square foot for various types of commercial roofing:
- Single-Ply Membranes: $3.50 – $7.50
- Modified Bitumen: $4.00 – $7.50
- PVC (Polyvinyl Chloride): $5.50 – $9.50

For an accurate estimate, it’s best to consult with professional commercial roofers.
How Long Does It Take to Install a New Commercial Roof?
In general, a small to medium-sized roof typically takes one to three weeks to complete, while a larger or more complex roof may take three to six weeks to complete. The time required to install a new commercial roof can vary depending on several factors:
- Size of the Roof: Larger roofs take longer to install.
- Type of Roofing Material: Some materials, like metal or TPO, may take longer to install than others.
