How Long Does a Commercial Roof Last?

One of the most significant investments for any commercial entity is the building itself, specifically, the roof. This brings us to a question that every property manager, homeowner, or business owner has asked at one point - how long does a commercial roof last? The lifespan of a commercial roof depends on a multitude of factors, which we’ll delve into in this blog post.

Factors Affecting the Lifespan of a Commercial Roof

Type of Commercial Roofing Materials

The durability of commercial roofs will depend largely on the type of materials used. Here are a few common types:

• EPDM Roofing: Also known as rubber roofing, EPDM (ethylene propylene diene terpolymer) is a popular choice for flat roofs due to its durability and cost-effectiveness.

• PVC Roofing: PVC (polyvinyl chloride) roofing is known for its strength and flexibility. It’s highly resistant to fire, wind, and chemical exposure.

• Modified Bitumen Roofing: This multi-layer roofing is noted for its flexibility during temperature fluctuations and resistance to leaks.

• Built-Up Roofing (BUR): BUR systems consist of alternating layers of bitumen and reinforcing fabrics creating a finished membrane, which works well with flat roofs.

• Thermoplastic Polyolefin (TPO): TPO roofs are heat-reflective and energy efficient, which makes them an excellent choice for commercial buildings.

• Asphalt Shingles for Commercial Buildings: While typically used on residential properties, asphalt shingles can be a viable option for smaller commercial buildings due to their aesthetic appeal and durability.

Roof Installation Quality

The longevity of a commercial roof is also determined by how well it’s installed.

Importance of Choosing Experienced Commercial Roofing Contractors

Choosing a reputable and experienced roofing contractor can make a considerable difference to the lifespan of your roof. A poorly installed roof can lead to frequent repairs, leaks, and ultimately, premature replacement.

Ensuring the Roof Is Properly Installed

A well-installed roof should have correctly installed flashings, tightly sealed seams, and no areas of ponding water. All of which contribute to a longer-lasting roof.

Climate and Weather Conditions

Impact of Weather on Flat Roofs and Slope Roofs

Weather conditions significantly affect roof longevity. For instance, flat roofs can accumulate water if not correctly designed, leading to leaks and damage. Slope roofs, on the other hand, can be more prone to wind damage.

UV Exposure and Temperature Fluctuations

UV radiation can cause roofing materials to deteriorate over time, while frequent temperature changes can cause expansion and contraction, leading to cracks and leaks.

Maintenance and Inspection Frequency

Recommended Roof Inspection Schedule

Regular inspections and maintenance are key to extending your roof’s lifespan. The National Roofing Contractors Association recommends at least two roof inspections annually, preferably in the spring and fall.

Common Roof Repair Needs

Regular inspections can help identify common repair needs, such as leaky seams, ponding water, or damaged flashing, before they turn into larger, more costly problems.

Roof Design and Structure

Slope Roof vs. Flat Roof Design

The design of your roof can also impact its lifespan. Slope roofs tend to have fewer leaks and longer lifespans than flat roofs due to their ability to shed water more effectively.

Importance of Proper Drainage Systems

A well-designed drainage system is critical to prevent water accumulation and ensure the durability of your roof.

Typical Lifespan of Different Commercial Roofing Systems

Different roofing systems have different expected lifespans under ideal conditions:

• EPDM Roofing: 20-30 years
• PVC Roofing: 20-30 years
• Modified Bitumen Roofing: 20-25 years
• Built-Up Roofing (BUR): 15-30 years
• Thermoplastic Polyolefin (TPO): 15-25 years
• Asphalt Shingles for Commercial Buildings: 15-20 years

Signs It’s Time for a Roof Replacement

Knowing when to replace your roof can save you from costly water damage and other related issues. Here are a few signs that it might be time for a roof replacement:

• Visible Damage and Leaks: If your roof has extensive damage or frequent leaks, it may be more cost-effective to replace rather than repair it.
• Energy Efficiency Decline: A sudden increase in energy bills could indicate that your roof is no longer providing adequate insulation.
• Frequent and Costly Roof Repairs: If your roof requires frequent and expensive repairs, it’s probably time to consider a replacement.
• Expired Manufacturer Warranty: If your roof’s warranty has expired, it may be more vulnerable to damage and less cost-effective to maintain.

How to Extend the Lifespan of a Commercial Roof

Just as there are factors that can shorten a roof’s lifespan, there are also ways to extend it:

• Regular Roof Maintenance Plans: Regular inspections and preventive maintenance can help identify and address issues before they become major problems.
• Working with Certified Commercial Roofing Contractors: Experienced contractors will ensure your roof is properly installed and maintained, extending its lifespan.
• Installing Energy-Efficient Roofing Membranes: These can help reduce the impact of UV radiation and temperature fluctuations.
• Scheduling Roof Inspections After Severe Weather: Weather events can cause unseen damage. Regular inspections can help catch and address these issues early.

Choosing the Right Roofing Contractor for Long-Term Results

The right roofing contractor can significantly impact the longevity of your commercial roof. Here are some things to consider:

• Certifications and Industry Credentials: Contractors with certifications have demonstrated a commitment to industry standards and best practices.
• Experience in Roofing Projects for Commercial Buildings: Experience matters. Contractors with specific commercial roofing experience will be able to help you make the best choices for your property.
• Customer Reviews and Testimonials: These can provide valuable insights into a contractor’s reliability, quality of work, and customer service.
