TL;DR

Water damage is a major threat to commercial roofs, often beginning with small leaks that can cause serious structural damage if not addressed promptly. Regular inspections, proper drainage systems, and timely repairs are essential to prevent costly downtime and protect your building.

Even the most durable commercial roofs are not immune to the dangers of water intrusion. A minor leak can slowly become a significant problem, leading to mold growth, interior damage, and business disruptions. This post explores how water damage happens, what signs to look for, and how proactive maintenance can save you thousands in repair costs.

The Anatomy of a Roof Leak: How Water Intrusion Starts

Water can infiltrate your commercial roof through weak spots that develop over time. Below are some common entry points for leaks:

1. Roof Penetrations
   Vents, chimneys, HVAC units, and skylights require seals and flashing, which degrade over time. When these areas weaken, they become prime targets for leaks.
2. Drainage Issues
   Flat commercial roofs often rely on a network of drains and gutters to remove rainwater. Clogs or damaged drains allow water to pool, increasing the chances of seepage and structural damage.
3. Seam Separation
   For membrane roofs like EPDM or TPO, seams are the most vulnerable spots. Over time, exposure to temperature changes and UV rays can cause seams to loosen or separate, leading to leaks.
4. Punctures and Tears
   Heavy foot traffic, falling debris, or sharp tools used during rooftop maintenance can puncture membranes, creating hidden paths for water to enter.

How to Detect Water Damage and Leaks Before It’s Too Late

Early detection can prevent small leaks from turning into major headaches. Here are some common signs of water damage to look out for:

1. Interior Water Stains or Discoloration
   Yellow or brown stains on ceilings and walls are often the first signs of hidden leaks.
2. Mold or Musty Odors
   Persistent dampness due to unnoticed leaks creates an environment perfect for mold growth, which can harm indoor air quality.
3. Warped Roof Membranes or Blisters
   Flat roofs with membrane systems may show bubbles or blisters, indicating water has penetrated the surface layers.
4. Standing Water on the Roof
   Pooled water that remains after 48 hours is a sign that drainage systems are not working effectively.
5. Increased Utility Bills
   Water damage compromises insulation, making your HVAC system work harder to maintain temperature, which can spike energy costs.

Effective Strategies to Prevent Roof Leaks and Water Damage

Preventive maintenance is key to extending the life of your roof and avoiding costly repairs. Here’s what we recommend:

1. Regular Roof Inspections
   Schedule inspections at least twice a year, particularly before and after storm seasons. Focus on seams, flashing, and drainage systems.
2. Gutter and Drain Maintenance
   Keep gutters and downspouts clear of debris to ensure water flows away from the roof. Inspect internal drains for blockages.
3. Use Roof Coatings
   Applying a protective coating to membranes or metal roofs can prevent cracking and UV damage.
4. Seal Roof Penetrations
   Regularly inspect and reseal areas around HVAC units, vents, and chimneys to maintain water-tight seals.
5. Invest in Moisture Detection Technology
   Modern leak detection systems use sensors to monitor moisture levels and alert you to water intrusion before it becomes visible.

What to Do if You Discover a Leak

If you find signs of water intrusion, it’s essential to act quickly. Here are the steps to follow:

1. Document the Damage
   Take photos and detailed notes of the affected areas. This will help with insurance claims.

Commercial roofs are built to withstand a lot, but even the toughest roofing systems aren’t immune to wind damage. Strong gusts can create problems ranging from minor shingle shifts to catastrophic roof failure, compromising your building’s structure and exposing it to leaks and other issues. In this post, I’ll walk you through how to spot wind damage early, ways to prevent it, and what steps you can take if it occurs.

Understanding Wind Damage: Why It Happens

Wind damage often begins at the most vulnerable points of a roof—such as edges, corners, and seams—where gusts can loosen roofing materials. Once a small piece is compromised, the wind gets under the surface, tearing larger sections away. Here are key factors that determine your roof’s vulnerability to wind:

1. Roof Age: Older roofs lose durability over time, making them more prone to wind damage.
2. Roof Type: Flat roofs may experience “uplift” pressure, while sloped roofs are more susceptible to shingle lifting.
3. Installation Quality: Poor installation leaves gaps and weak spots that wind can easily exploit.
4. Building Height and Location: Taller buildings and those in open areas are more exposed to high wind pressures.

Signs of Wind Damage on Commercial Roofs

Early detection is crucial to prevent minor issues from escalating into expensive repairs. Here’s what to watch for:

1. Lifted or Torn Materials: Look for shingles, metal sheets, or membrane seams that appear loose or out of place.
2. Debris on Roof Surface: Accumulated debris can block drainage systems and indicate nearby wind damage.
3. Visible Gaps or Open Seams: Gaps in roofing materials can let water in, leading to internal damage.
4. Damaged Flashing: Flashing around vents, chimneys, and skylights may be bent or missing.
5. Interior Leaks or Water Stains: Wind damage can lead to leaks, which often show up as ceiling stains or water drips.

After a severe hailstorm in the Twin Cities, many homeowners find themselves scrambling to assess the damage. Unfortunately, this is also when disreputable contractors try to take advantage of people in need of roof repairs. At Right Now Roofing, we’ve heard the horror stories, and we want to make sure you’re informed and protected. Here are 10 steps you can take to safeguard your home and avoid being scammed.

1. Understand the Scope of Damage to Your Home

In Minnesota, severe hail can damage your roof, siding, and windows. Before calling in an insurance claim, inspect the damage yourself or have a reputable contractor provide photo documentation. Make sure you agree with their findings. Filing unnecessary claims could harm you in the future and raise your premiums.

2. Verify the Company You’re Considering

Do a quick Google search and check reviews for any roofing company you’re considering in the Twin Cities. Look them up on the Better Business Bureau (BBB) to check for complaints or negative history. If they’re not a member of the BBB, that’s a red flag. Additionally, platforms like Angi and Nextdoor can provide valuable local insights from your neighbors.

3. Ask for Local References

Be sure to ask for references specific to the Twin Cities area and take the time to contact them. Ask about their experience, the quality of the work, and if the company fulfilled their promises. A company that regularly works in your local area should have plenty of references.

4. Clarify the Role of the Salesperson

In Minnesota’s storm restoration industry, it’s common for salespeople to serve multiple roles, such as job supervisor or production manager. Ask your salesperson what their role will be during your project and ensure there’s clear accountability for overseeing the work.

5. Carefully Read Contracts

Never feel pressured into signing an “insurance proceeds agreement” without fully understanding it. In Minnesota, you have the legal right to cancel any contract within three days of signing. Make sure you take the time to read the contract thoroughly and don’t be rushed by any high-pressure tactics.

6. Confirm Insurance Coverage

Ensure that the roofing company and any subcontractors have both workers’ compensation and liability insurance. This protects you as a homeowner if accidents occur on your property. You can ask for proof of insurance and verify it before any work begins.

7. Review Your Insurance Loss Statement

Your insurance loss statement will detail what’s covered, but sometimes items can be left off that are necessary for code compliance in Minnesota. Contractors may need to supplement for these items. Make sure you understand what is being covered and ask questions if anything is unclear.

8. Don’t Pay Until Materials Are Delivered

In Minnesota, it’s not uncommon for roofing projects to be delayed due to weather. Don’t hand over your Actual Cash Value (ACV) check before materials arrive on your property. The safest approach is to provide a down payment on the day the project starts, after confirming that materials are on-site and work has begun.

9. Secure Lien Waivers Before Final Payment

Before making your final payment, ensure you receive unconditional lien waivers from both the material suppliers and subcontractors. These waivers guarantee that all bills have been paid, protecting you from future legal claims on your property.

10. Ensure Supervision Throughout Installation

A reputable roofing company will have a supervisor present throughout the project. This person should:

• Be there at the start of the tear-off to inspect the decking.
• Oversee the installation of the ice and water shield, especially important for Minnesota’s harsh winters.
• Perform a final inspection upon completion to ensure the job was done to code and no property was damaged.

Having a dedicated supervisor helps identify underlying issues and ensures proper communication with your insurance company.

Conclusion

By following these steps, you’ll protect yourself from scammers and ensure your roofing project goes smoothly. Right Now Roofing is proud to serve homeowners in the Twin Cities area with integrity and professionalism. If you’ve been affected by a recent storm, contact us today for a free consultation.

When a storm hits or a tree falls, the last thing homeowners want to think about is insurance paperwork. However, documenting roof damage correctly can make all the difference when it comes to filing a successful insurance claim. In Minnesota, certain rules and procedures can help ensure that you’re properly covered for any roof-related incidents. Here’s what you need to know.

Step 1: Understand Minnesota’s Insurance Requirements

In Minnesota, most homeowners’ insurance policies cover damage caused by storms, hail, wind, or falling objects such as trees. However, the coverage for the cost of repairs largely depends on the policy specifics. Minnesota law requires that claims for damage be filed within a reasonable amount of time after the incident occurs. Some policies may have a statute of limitations, so check your policy for specific time frames.

Step 2: Start by Documenting the Damage Immediately

After ensuring your home is safe, your first step is to take clear and comprehensive photos of the roof damage. Include wide shots of the roof and close-up photos of any visible issues like missing shingles, punctures, or debris. It’s also important to:

• Use timestamps on photos: Minnesota insurance adjusters often require proof of when the damage occurred. Most smartphones will automatically do this, but make sure the settings are enabled.
• Document from multiple angles: Take photos from ground level and, if safe, a ladder or drone.
• Capture the environment: Minnesota weather can be unpredictable, so be sure to document the conditions during and after the damage occurred (e.g., fallen trees, snow, hail).

Step 3: Write a Detailed Incident Report

Beyond photos, write down the events leading up to and following the incident. Include:

• The date and time of the event.
• Weather conditions before and after the damage (e.g., severe winds, heavy snowfall).
• Any actions you took to mitigate further damage (such as placing a tarp).

Step 4: Preserve Evidence for the Insurance Adjuster

Insurance companies in Minnesota may send an adjuster to evaluate the damage, so avoid making permanent repairs until after the inspection. However, it’s wise to take temporary measures, such as placing a tarp, to prevent further damage. Keep any receipts for temporary repairs, as these can sometimes be reimbursed.

Step 5: Be Aware of Minnesota’s “Right to Repair” Laws

Minnesota homeowners have the right to choose their own contractor for repairs. Your insurance company might suggest certain contractors, but you’re not obligated to use them. At Right Now Roofing, we frequently work with insurance companies to ensure repairs meet all necessary requirements.

Hailstorms can cause serious damage to commercial roofs, often in ways that aren’t immediately visible. Whether it’s a minor impact or significant structural damage, hail poses risks that, if left unaddressed, could cost building owners substantial sums in repairs and lost revenue due to downtime.

Understanding how hail can affect your roof is crucial for making informed decisions about inspections, repairs, and preventative measures. In this post, we will explore the different types of hail damage, the long-term risks, and why regular roof inspections after a hailstorm are vital for maintaining the integrity of your commercial building.

Understanding Hail and Its Impact on Commercial Roofs

Hail forms when updrafts in a storm carry rain droplets into extremely cold areas of the atmosphere, where they freeze and eventually fall to the ground. While smaller hailstones might only cause superficial damage, larger hailstones can compromise the structure of your commercial roof in significant ways. It’s not just about the visible dents and cracks—hail can damage the underlying structure of the roof, weakening its ability to protect your building from future weather events.

Common Types of Hail Damage on Commercial Roofs:

1. Dents and Impact Marks: Hail often leaves visible dents or impact marks on roofing materials, especially on metal roofs. These dents can compromise the roof’s ability to effectively drain water, leading to ponding and eventual leaks.
2. Punctures and Cracks: In cases of larger hailstones, the impact may cause punctures or cracks in the roofing membrane, which opens the door to water intrusion.
3. Shingle Granule Loss: If your commercial roof uses asphalt shingles, hailstorms can knock off the protective granules, leaving the shingles more vulnerable to UV damage and reducing the overall lifespan of the roof.
4. Membrane Damage: For flat or low-slope commercial roofs with rubber, TPO, or PVC membranes, hail can create punctures or tears, which may not be visible at first but can lead to serious water damage over time.
5. Flashing Damage: Flashing around chimneys, vents, and other roof penetrations can also be damaged by hail, which can lead to water seeping into the building.

The Long-Term Risks of Ignoring Hail Damage

Ignoring hail damage can lead to a host of problems that extend far beyond the roof itself. Here are some of the most significant risks:

1. Water Leaks and Mold Growth: Small cracks or punctures in the roof can allow water to infiltrate, leading to leaks. Over time, this moisture can promote mold growth, which poses health risks to building occupants and can require costly remediation.
2. Structural Weakness: Hail damage can weaken the structural integrity of your roof. Over time, this may lead to sagging, collapse, or other severe issues that compromise the safety of your building.
3. Energy Inefficiency: Hail damage to your roof can impact its insulation properties, making your building less energy efficient. This can lead to higher heating and cooling costs, putting a strain on your budget.
4. Decreased Property Value: A damaged roof can significantly reduce the value of your commercial property, especially if potential buyers or tenants learn about the damage.
5. Voided Warranties: Some roof warranties require regular maintenance and inspections, particularly after weather events like hailstorms. Failing to address damage promptly can void your warranty, leaving you on the hook for costly repairs.

The Importance of Regular Roof Inspections

After a hailstorm, it’s essential to have a qualified roofing professional inspect your commercial roof, even if there doesn’t appear to be significant damage. Often, the most serious types of damage aren’t immediately visible to the untrained eye. A thorough inspection can identify small cracks, punctures, or membrane damage that could lead to more serious issues if left unaddressed.

In addition to post-storm inspections, it’s a good idea to schedule routine roof maintenance to catch potential problems early and ensure that your roof is in good shape before the next hailstorm hits. Many roofing companies offer maintenance programs that include regular inspections, which can extend the life of your roof and protect your investment.

Comparison of Hail Damage by Hailstone Size

Different sizes of hailstones cause different levels of damage. Here’s a comparison of typical roof damage based on hailstone diameter:

What to Do After a Hailstorm: Step-by-Step Guide for Building Owners

If your commercial building has been through a hailstorm, follow these steps to ensure your roof’s integrity and avoid long-term damage:

1. Inspect the Surrounding Area: Before climbing onto the roof, inspect the ground around your building for signs of hail, such as damaged trees, vehicles, or outdoor equipment.
2. Perform a Visual Roof Inspection: If it’s safe to do so, look for visible damage to your roof, such as dents, punctures, or granule loss. If your roof has a rubber or synthetic membrane, check for tears or punctures.
3. Hire a Professional Roofing Contractor: Have a licensed roofing contractor perform a thorough inspection. They can identify more subtle types of damage and recommend necessary repairs.
4. File an Insurance Claim: If your roof has been damaged by hail, contact your insurance company to file a claim. Make sure to document the damage with photos and inspection reports from your roofing contractor.
5. Schedule Repairs: Depending on the extent of the damage, you may need to schedule immediate repairs or a complete roof replacement. Be sure to get quotes from several contractors and choose one with experience in hail damage repair.
6. Plan for Future Storms: After your roof is repaired, consider investing in preventive measures to minimize future hail damage. This could include installing more durable roofing materials or reinforcing vulnerable areas of your roof.

Choosing the Right Roofing Materials for Hail-Prone Areas

If your commercial building is in a region prone to hailstorms, it’s essential to choose roofing materials that can withstand hail damage. Here are a few options to consider:

• Metal Roofing: Metal is one of the most hail-resistant roofing materials available. While hail may cause dents, it is less likely to puncture metal roofing than other materials.
• Impact-Resistant Shingles: Some manufacturers offer asphalt shingles that are designed to withstand hail impacts. These shingles have a reinforced layer that helps prevent granule loss and cracks.
• Single-Ply Membranes (TPO, EPDM, PVC): While single-ply membranes can be punctured by large hail, newer versions offer increased durability. For added protection, you can opt for a thicker membrane or reinforced seams.
• Clay or Concrete Tiles: These materials are highly resistant to hail, but they can crack under the impact of very large hailstones. However, they offer excellent protection in regions with moderate hailstorms.

Conclusion

Hail damage to commercial roofs is a serious concern that should not be ignored. From minor dents to major structural damage, hail can compromise your roof’s ability to protect your building and its contents. By understanding the different types of hail damage, recognizing the risks of ignoring it, and investing in regular roof inspections, you can prolong the life of your roof and avoid costly repairs in the future. If your commercial building has recently experienced a hailstorm, be sure to contact a roofing professional to assess the damage and recommend the best course of action.

The main difference between TPO and EPDM roofing lies in their material composition and energy efficiency. TPO is a single-ply membrane known for its reflective white surface, which helps reduce cooling costs in hot climates. In contrast, EPDM is a synthetic rubber membrane, typically black, known for its durability and proven track record, making it ideal for buildings in regions with extreme temperature fluctuations.

When it comes to selecting the right roofing material for your commercial building, the choice can often feel overwhelming. With so many options on the market, it’s essential to understand the differences between materials and how they can impact your building’s longevity, energy efficiency, and overall costs. Two of the most popular commercial roofing materials today are Thermoplastic Olefin (TPO) and Ethylene Propylene Diene Monomer (EPDM). Each has its strengths and weaknesses, making it crucial to understand which might be better suited for your specific needs.

Understanding TPO Roofing

TPO roofing is a relatively new roofing material, gaining popularity due to its energy efficiency and cost-effectiveness. It is a single-ply membrane composed primarily of a blend of polypropylene and ethylene-propylene rubber, which gives it flexibility and strength. TPO membranes are typically white, reflecting the sun’s UV rays, making them an energy-efficient option for commercial buildings, especially in warmer climates.

One of the key advantages of TPO is its ability to resist dirt, algae, and mildew growth, which can be particularly beneficial for buildings located in humid or coastal areas. Additionally, TPO roofs are known for their heat-welded seams, which provide superior strength and durability compared to adhesive-based systems.

However, TPO is not without its challenges. Because it is a newer material, the long-term durability and performance of TPO roofs are still being studied. Some earlier formulations had issues with seam failures and cracking under extreme temperature fluctuations, but many manufacturers have since improved their products to address these concerns.

Understanding EPDM Roofing

EPDM roofing has been a staple in the commercial roofing industry for decades. It is a synthetic rubber membrane made primarily of ethylene and propylene derived from oil and natural gas. EPDM roofs are typically black, though white EPDM is available for those seeking a more reflective surface.

One of the most significant advantages of EPDM is its proven track record. With over 50 years of performance data, EPDM has demonstrated its ability to withstand a wide range of weather conditions, from extreme heat to freezing temperatures. Its flexibility makes it highly resistant to thermal shock, and its simple installation process makes it a cost-effective option for many commercial building owners.

EPDM roofs are also known for their ease of maintenance and repair. Punctures and tears can often be repaired with simple patches, and the material’s long life expectancy makes it a popular choice for low-slope commercial roofs.

However, EPDM’s black surface can absorb heat, leading to higher cooling costs in warmer climates. This issue can be mitigated by using a white EPDM membrane or by applying a reflective coating, but these solutions can add to the overall cost.

Real-Life Story #1: The Warehouse Dilemma

A few years ago, we were approached by a client who owned a large warehouse in an area downtown Minneapolis that had zero shade or other buildings around it to allow the roof to cool in the summer. The building had an aging EPDM roof that had been in place for over 25 years. While the EPDM roof had served the building well, the client was facing skyrocketing cooling costs during the summer months. The black surface of the EPDM was absorbing the sun’s heat, making it nearly impossible to keep the warehouse cool without running the air conditioning constantly.

After assessing the situation, we recommended replacing the old EPDM roof with a new TPO roof. The reflective white surface of the TPO membrane promised to reduce the building’s cooling costs significantly. The client was initially hesitant due to concerns about TPO’s long-term durability, but after discussing the advancements in TPO technology and offering a solid warranty, they decided to make the switch.

The result? The client reported a noticeable decrease in cooling costs during the first summer after the installation. The TPO roof not only helped lower energy bills but also provided a clean, modern look to the building. This experience reinforced our belief in the effectiveness of TPO for buildings in hot climates.

Real-Life Story #2: The Manufacturing Facility

On the other side of the spectrum, we worked with a manufacturing facility located in St. Paul. The owner was very particular about having a roof that can withstand our harsh winters. He wanted it to withstand our crazy Minnesota temperature extremes without frequent maintenance or repairs.

Given the facility’s location and the owner’s desire for a long-lasting, low-maintenance roof, we recommended sticking with an EPDM membrane. The flexibility and durability of EPDM made it the ideal choice for a building that would be exposed to such a wide range of temperatures. Additionally, the black EPDM surface would help melt snow and ice more quickly during the winter months, reducing the risk of leaks or damage.

Several years after the installation, the owner reported that the EPDM roof had performed exceptionally well, withstanding heavy snow, ice, and summer heat without any significant issues. The decision to go with EPDM proved to be a wise investment for the facility, providing peace of mind and protecting the building for years to come.

Which Roofing Material is Right for You?

When deciding between TPO and EPDM for your commercial building, there are several factors to consider:

1. Climate: If your building is located in a hot climate where cooling costs are a concern, TPO’s reflective properties may offer significant energy savings. On the other hand, if your building is in a region with extreme temperature fluctuations or heavy snowfall, EPDM’s proven durability might be the better choice.
2. Budget: Both TPO and EPDM are cost-effective options, but TPO may offer better energy efficiency, potentially lowering long-term operational costs. However, EPDM’s long track record and ease of maintenance can also provide excellent value.
3. Aesthetics: If the appearance of your roof is important, TPO’s clean, white surface might be more appealing, particularly for modern or minimalist designs. EPDM, while typically black, can also be installed in white or coated to achieve a similar look.
4. Longevity: EPDM has a proven lifespan of 20-30 years, while TPO is newer and still accumulating long-term performance data. However, advancements in TPO technology suggest it may also provide excellent durability.

Ultimately, the best choice for your commercial roof depends on your specific needs, location, and budget. At Right Now Roofing, we’re here to help you navigate these options and choose the roofing material that will best protect your building for years to come.
