Presented by Motor City Roofers, Detroit, Michigan
When it comes to the maintenance, repair, or installation of a commercial flat roof, hiring the right contractor is a decision that will impact your business for years to come. Commercial flat roofs are an essential part of your building, protecting your property, employees, and equipment from harsh weather conditions. However, their unique design, materials, and structure require specialized knowledge and expertise. At Motor City Roofers in Detroit, Michigan, we understand the complexities of flat roofing systems and the importance of working with qualified professionals to get the job done right.
In this guide, we’ll explore what commercial flat roofing contractors do, the types of services they offer, and how to choose the right one for your business.

What Is a Commercial Flat Roofing Contractor?
Commercial flat roofing contractors specialize in the design, installation, repair, and maintenance of flat roofing systems. These roofs, characterized by their minimal slope, are commonly used in industrial buildings, warehouses, schools, and office complexes. Flat roofs are popular because they maximize usable space and are cost-effective compared to traditional sloped roofs. However, they also pose unique challenges, such as drainage issues, which require expert attention.
Professional roofing contractors bring specialized skills, equipment, and materials to ensure your flat roof meets industry standards. From initial consultations to the final touches, a reliable contractor will guide you through the entire process, keeping you informed and ensuring your roof provides long-lasting protection.

Services Offered by Commercial Flat Roofing Contractors
Commercial flat roofing contractors provide a variety of services tailored to the specific needs of flat roofing systems. Here’s an overview of the key services:

1. Flat Roof Installation
Building a flat roof requires careful planning and precision. Contractors evaluate factors like the building’s size, purpose, and location before recommending suitable roofing materials, such as EPDM, TPO, PVC, or modified bitumen. A skilled contractor will ensure the roof is installed correctly to prevent future problems, such as leaks or structural issues.

2. Roof Repair
Flat roofs are prone to wear and tear, especially in harsh weather conditions like Detroit’s freezing winters and hot summers. A professional roofing contractor can identify and fix issues like ponding water, leaks, cracks, or membrane punctures. Early repair prevents minor problems from turning into costly repairs or replacements.

3. Roof Replacement
When a flat roof reaches the end of its lifespan, a complete replacement may be necessary. Experienced contractors can guide you through the process, helping you choose the best materials and ensuring the replacement is done efficiently with minimal disruption to your business operations.

4. Roof Coatings and Restoration
Roof coatings, such as silicone or acrylic, are an excellent way to extend the life of your flat roof. Contractors apply these coatings to create a protective layer that enhances durability, improves energy efficiency, and prevents leaks. Restoration is a cost-effective alternative to full replacement and can add years to your roof’s lifespan.

5. Preventive Maintenance
Preventive maintenance is essential for prolonging the life of a flat roof. Contractors offer services such as inspections, cleaning, and minor repairs to keep the roof in optimal condition. Regular maintenance can help detect issues early and save money in the long run.

6. Emergency Roof Repairs
Unpredictable weather or unexpected accidents can cause sudden damage to a flat roof. Reliable contractors offer emergency repair services to quickly address urgent problems and minimize disruptions to your business.

Qualities to Look for in a Commercial Flat Roofing Contractor
Not all roofing contractors are created equal, and choosing the right one can make all the difference. Here are the key qualities to consider:

1. Experience and Expertise
A contractor’s experience with commercial flat roofing systems is critical. Look for a company with a proven track record of successful projects and expertise in handling the specific roofing material you need.

2. Licensing and Insurance
Always hire a licensed contractor who complies with local regulations. Additionally, ensure they carry proper insurance, including liability and worker’s compensation, to protect you from any liability in case of accidents.

3. Reputation and Reviews
Research the contractor’s reputation by reading online reviews and testimonials from previous clients. A reputable contractor will have a history of satisfied customers and positive feedback.

4. Warranty and Guarantees
A trustworthy contractor stands behind their work. Ask about warranties for materials and workmanship to ensure you’re covered in case of future issues.

5. Transparent Pricing
Avoid contractors who provide vague or overly low estimates. A professional contractor will offer a detailed, written estimate outlining the scope of work, materials, and costs.

6. Communication Skills
Effective communication is essential for a smooth roofing project. Choose a contractor who listens to your concerns, answers your questions, and keeps you informed throughout the process.

7. Safety Standards
Roofing projects involve risks, especially on large commercial buildings. Ensure the contractor follows strict safety protocols and uses proper equipment to protect workers and property.

​A Comprehensive Guide to Commercial Roof Inspection: Insights from Motor City Roofers in Detroit, Michigan
As a business owner or property manager, maintaining the structural integrity of your commercial building is essential to protecting your assets and minimizing costly repairs. One of the most critical parts of your building is its roof, which takes on the brunt of weather exposure and environmental wear. Routine commercial roof inspections are essential to identify problems early, prevent significant damage, and extend the roof's lifespan.
At Motor City Roofers, we specialize in commercial roofing services in Detroit, Michigan, where varying weather patterns—from summer heatwaves to harsh winter snow—can impact roof durability. This guide will walk you through the essentials of commercial roof inspections, offering a checklist of items to examine and insights into why regular inspections are a smart investment for any commercial property.

Why Commercial Roof Inspections Are Important
A commercial roof is constantly exposed to the elements, from rain and snow to UV rays and high winds. Over time, these conditions can cause damage that may go unnoticed without regular inspections. Here are some reasons why inspecting your commercial roof is crucial:

1. Prevent Costly Repairs: Routine inspections help catch minor issues before they escalate into significant problems that require extensive repairs or even a full replacement.
2. Prolong Roof Lifespan: Regular maintenance and inspections can extend the life of your roof, saving you money in the long run by postponing replacement.
3. Energy Efficiency: A well-maintained roof ensures your building stays energy-efficient, reducing heating and cooling costs.
4. Maintain Aesthetic Appeal: Regular inspections help keep your roof looking good, contributing to the building's overall appeal.
5. Compliance with Warranty Requirements: Many roofing warranties require regular inspections and maintenance to remain valid. Failing to inspect your roof could void your warranty.

How Often Should You Inspect Your Commercial Roof?
At Motor City Roofers, we recommend inspecting your commercial roof at least twice a year—ideally in the spring and fall. Seasonal inspections help you address issues that arise due to extreme weather. Additionally, it’s wise to conduct inspections after severe storms, high winds, or heavy snowfall, as these events can cause sudden damage.
Essential Tools for a Commercial Roof InspectionA thorough commercial roof inspection requires a few key tools:

• Ladder (for safe access)
• Binoculars (to inspect hard-to-reach areas)
• Infrared camera (to detect moisture)
• Flashlight (for interior inspections)
• Notepad or inspection software (to document findings)
• Tape measure (to assess damage size)
• Digital camera (to take photos for records)

Key Areas to Inspect
A comprehensive roof inspection covers multiple areas and components. Here’s a checklist of the most crucial aspects to examine:

1. Roof Membrane
The roof membrane is the topmost layer of your roof and serves as the primary barrier against water. Common issues with the membrane include cracks, punctures, blisters, and seam separations. Over time, exposure to UV rays and temperature fluctuations can degrade the membrane, causing it to lose its protective qualities.
Inspect the membrane for any signs of wear and tear, and ensure there are no loose or damaged sections. Even small punctures or cracks can allow water to seep through, leading to interior damage and mold growth.

2. Flashing
Flashing is used around roof penetrations, edges, and corners to prevent water from entering. Loose, corroded, or damaged flashing can compromise the roof’s waterproofing. During the inspection, examine all flashing for cracks, rust, or lifting. Pay special attention to areas around vents, skylights, chimneys, and HVAC units, as these are common sites for flashing failure.

3. Drains and Gutters
An effective drainage system is essential for keeping water from pooling on your roof. Clogged or damaged drains and gutters can lead to ponding water, which puts undue stress on the roof and can cause structural damage. Check all drains, downspouts, and gutters for debris, cracks, or blockages. Ensure water flows freely through the drainage system.

4. Roof Penetrations
Roof penetrations, such as vents, pipes, and HVAC units, create weak points on the roof. Inspect these areas for signs of wear, as well as any gaps or holes that could allow water to enter. Make sure the seals around each penetration are intact and that there is no evidence of rust or corrosion.

5. Interior Ceilings and Walls
A roof inspection should include an interior assessment of the building. Check ceilings and walls for water stains, mold, or peeling paint, which could indicate a leak. If you find any signs of moisture or water damage, trace them back to the roof to determine the source of the issue.

6. Seams and Joints
Roof seams and joints are vulnerable areas that can develop leaks if not properly maintained. Inspect all seams for separations, gaps, or other signs of failure. If you notice any loose or open seams, repair them promptly to prevent water infiltration.

7. Signs of Ponding Water
Flat commercial roofs are particularly susceptible to ponding water, which occurs when water pools on the roof instead of draining. Prolonged ponding can lead to membrane damage, structural strain, and accelerated deterioration. Look for depressions or areas where water has collected. If ponding is a recurring problem, consider implementing additional drainage solutions.

8. Roof Surface Conditions
Inspect the overall condition of the roof surface. Look for signs of general wear, including fading, granule loss (if applicable), and damage caused by UV exposure. Also, check for loose or damaged roofing material that may need repair or replacement.

9. Parapet Walls and Copings
Parapet walls are common on commercial buildings, especially those with flat roofs. Inspect these walls and their copings (protective coverings on top of parapets) for cracks, loose material, and signs of water damage. Damaged parapet walls can lead to water infiltration, compromising the entire roofing system.

10. Previous Repairs
If your roof has undergone any previous repairs, check these areas to ensure they’re still intact. Repairs that were not completed correctly or have deteriorated over time can become weak points in the roof and cause additional problems.

Documenting Your Inspection
Proper documentation is critical to a successful roof inspection. Motor City Roofers recommends creating a checklist of all the areas inspected, taking photos of any issues found, and recording detailed notes. Digital tools and inspection software can help streamline this process and make it easier to track issues over time. Good documentation also supports warranty claims and helps plan maintenance schedules.

When to Call a Professional
While property owners or managers can conduct basic visual inspections, certain aspects of a roof inspection require expertise and specialized equipment. If you notice significant damage, suspect moisture intrusion, or have concerns about the roof’s structural integrity, it’s best to contact a professional roofing contractor. A licensed roofing professional, like those at Motor City Roofers, can conduct a thorough inspection, identify potential issues, and provide expert recommendations.

Regular commercial roof inspections are a proactive measure to maintain the longevity and performance of your roofing system. By catching small issues before they become major problems, inspections can save you money, extend your roof’s life, and protect your building’s interior from damage. For Detroit business owners, partnering with a reputable roofing contractor, such as Motor City Roofers, ensures your roof stays in optimal condition year-round.  Whether it’s a seasonal check-up or a post-storm assessment, a comprehensive inspection plan is crucial for preserving your investment and ensuring the safety of your commercial property.

What is the Most Common Roofing Material? A Guide from Motor City Roofers in Detroit, Michigan
When it comes to choosing the best roofing material for commercial or residential buildings, there’s no one-size-fits-all answer. The “best” material depends on a range of factors, including climate, building structure, cost, and maintenance needs. However, some roofing materials are consistently more popular than others, particularly for commercial properties where durability, cost-efficiency, and ease of installation play a key role in decision-making.

At Motor City Roofers, we understand the unique needs of commercial properties in Detroit, Michigan. Our region’s climate, with its harsh winters and humid summers, calls for roofing materials that can withstand significant temperature swings, heavy snow loads, and potentially damaging UV rays. Below, we’ll explore some of the most common roofing materials used today, their unique properties, and why certain materials are better suited for Detroit's climate.

1. Asphalt Shingles
Overview: Asphalt shingles are by far the most common roofing material for residential buildings across the United States and have also been used in some smaller commercial buildings. They are popular because they are affordable, versatile, and relatively easy to install. Asphalt shingles are typically made of fiberglass or organic materials, coated with asphalt and topped with mineral granules for added protection.
Pros:

• Affordability: Asphalt shingles are one of the most cost-effective roofing materials.
• Variety: They come in a wide range of colors and styles, making it easy to match architectural preferences.
• Ease of Installation and Repair: Installation is straightforward, and damaged shingles can be individually replaced.

Cons:

• Durability: Asphalt shingles are generally less durable than other commercial roofing materials and may not withstand Detroit’s intense winters and summers as well as other materials.
• Shorter Lifespan: Asphalt shingles have a lifespan of 20-30 years, which is shorter than many alternatives.

Best for: Residential buildings and small commercial buildings in areas with moderate climates.

2. TPO (Thermoplastic Polyolefin)
Overview: TPO is a single-ply roofing membrane made of a blend of polypropylene and ethylene-propylene rubber. It has gained popularity in commercial roofing due to its energy efficiency and cost-effectiveness. TPO is particularly appealing in areas with warmer climates, but it has also performed well in colder climates like Detroit’s.
Pros:

• Energy Efficiency: TPO membranes reflect UV rays, reducing cooling costs during hot summers.
• Durability: Resistant to punctures, tears, and most chemicals.
• Cost-Effective: TPO is typically more affordable than other commercial roofing options like PVC and EPDM.

Cons:

• Quality Variations: Since TPO is a relatively new material, the quality can vary significantly depending on the manufacturer.
• Seam Integrity: Over time, TPO seams may become vulnerable if not properly installed and maintained.

Best for: Flat or low-slope commercial roofs, particularly for properties looking to reduce energy costs.

3. EPDM (Ethylene Propylene Diene Monomer)
Overview: EPDM, commonly referred to as “rubber roofing,” is a synthetic rubber membrane that has been widely used in commercial roofing for decades. Its reputation for durability and flexibility in extreme temperatures has made it a top choice for flat roofs, particularly in areas with variable weather like Michigan.
Pros:

• Durability: EPDM can last up to 30 years or more with proper maintenance.
• Flexibility: This material can expand and contract with temperature changes, making it ideal for Detroit’s variable climate.
• Low Maintenance: EPDM is relatively low maintenance and can withstand UV exposure and ozone.

• Aesthetics: Black EPDM absorbs heat, which may increase cooling costs in the summer unless a reflective coating is applied.
• Vulnerability to Punctures: Though durable, EPDM can be punctured by sharp objects or debris, which can lead to leaks.

Best for: Flat and low-slope commercial roofs in variable climates, especially those looking for a long-lasting material.

4. Metal Roofing
Overview: Metal roofing is popular for both commercial and industrial properties due to its exceptional durability and longevity. Typically made from steel, aluminum, or copper, metal roofing systems can be used on low-slope and steep-slope roofs. Metal roofing is ideal for Detroit’s climate, as it can handle heavy snowfall, resist corrosion, and perform well under varying temperatures.
Pros:

• Longevity: Metal roofs can last 40-70 years, making them one of the longest-lasting roofing materials available.
• Weather Resistance: Metal roofing can withstand extreme weather conditions, including heavy snow, strong winds, and hail.
• Sustainability: Metal is highly recyclable, making it an eco-friendly option.

Cons:

• Cost: Metal roofs have a higher upfront cost than many other materials.
• Noise: Without proper insulation, metal roofs can be noisier during rain or hailstorms.
• Expansion and Contraction: Metal expands and contracts with temperature changes, which may lead to issues with fasteners over time.

Best for: Large commercial buildings in regions with harsh weather, especially those that prioritize longevity and minimal maintenance.

5. Modified Bitumen
Overview: Modified bitumen roofing is a multi-ply roofing system often used for flat or low-slope roofs. It is made from asphalt with added modifiers to enhance flexibility and durability. Modified bitumen can be applied through various techniques, including torch-down, cold adhesive, or self-adhered methods.
Pros:

• Durability: Modified bitumen is strong, puncture-resistant, and can withstand heavy foot traffic.
• Weather Resistance: It performs well under various weather conditions, including Detroit’s snowy winters.
• UV Resistance: Some modified bitumen systems are designed with UV resistance, helping to reduce heat absorption.

Cons:

• Installation Complexity: The installation process can be labor-intensive and requires professional expertise.
• Limited Lifespan: Modified bitumen roofing generally lasts around 20 years, which is shorter than some other commercial options.

Best for: Flat commercial roofs that need additional durability and resistance to weather and foot traffic.

6. PVC (Polyvinyl Chloride)
Overview: PVC roofing is another single-ply membrane option, similar to TPO, but with enhanced chemical and puncture resistance. PVC is especially popular in commercial applications where chemical exposure is common, such as restaurants and factories.
Pros:

• Chemical Resistance: PVC is resistant to grease, chemicals, and fire, making it ideal for certain commercial applications.
• Durability: Known for its durability and ability to withstand various environmental factors.
• Energy Efficiency: Reflects UV rays, helping to reduce cooling costs in the summer.

Cons:

• Cost: PVC roofing is generally more expensive than TPO and EPDM.
• Environmental Concerns: The production and disposal of PVC can have a greater environmental impact than some other materials.

Best for: Commercial roofs in sectors with specific requirements, such as food production and chemical processing, as well as buildings seeking energy-efficient solutions.
