What Is Waterproofing?
Commercial flat roof waterproofing systems create watertight rain, snow, and ice protection that helps you avoid the adverse effects of water seepage. Various issues cause roof leaks in Minnesota, including the UV light and humidity roofs are exposed to during the summer and the extreme cold, snow, and ice of winter.
Most low-slope roofs and roofing materials can be waterproofed, but may require different solutions. That’s why working with an experienced local roofing company that knows how to seal a flat roof and understands the area’s climate is critical. Whether it’s a rubber roof waterproof membrane or a roof sealant that protects foundations walls, your solution needs to address your specific type of roof.
Why Waterproof?
If you’re wondering why flat roof waterproofing might be a good solution for your business, we have the answers you’re looking for. Even the smallest leak in your roof can let water into your building and cause severe damage. Waterproofing your roof is more straightforward than a complete roof replacement while still offering many of the same benefits.
At the same time, a flat roof waterproofing system provides a longer-term solution than a quick repair. If you’re trying to decide between a one-time repair, a waterproof roof coating, or a complete roof replacement, here are six benefits to waterproofing to help you with the decision-making process:
1. Longevity
Flat roof waterproofing reduces the risk of critical damage. With a watertight roofing membrane, your roof has an additional layer of protection from wear, decay, and leaks caused by rain, snow, ice, and wind. At the same time, a flat roof waterproofing system reflects the sun’s damaging UV rays, reducing the impact of extreme heat and light on your roof. Rain, snow, and ice protection solutions last up to ten years, substantially extending your roof’s lifespan.
2. Cost Savings
Beyond reducing wear and tear, watertight roofing saves you money in the short term because it’s significantly cheaper than a complete overhaul or repeat repairs. Waterproofing layers also require maintenance less frequently. By extending the life of your existing roof with a water-resistant coating, you also experience significant cost savings in the long run.
3. Energy Efficiency
Because most flat roof waterproofing systems reflect heat and sunlight, you’ll save on HVAC costs in the summer by maintaining steadier building temperatures. Some watertight roofing solutions may even qualify for additional rebate and warranty programs. A one-time repair or complete roof replacement won’t have nearly as much of an impact on your building’s energy efficiency as waterproofing does.
4. Lower Humidity
A waterproof roof coating seals your building from water leakage and protects against the damaging effects of thermal shock. Flat roof waterproofing reduces the humidity levels in your building while also preventing mold growth. You, your employees, and your clients will all be more comfortable, plus you’re protected from more serious structural issues, like weakened foundation walls.
5. Low Maintenance
Coatings are much simpler to maintain and require fewer roof waterproofing repairs than your existing roof infrastructure. When maintenance and repairs are necessary, they’re generally much quicker to perform than on a conventional roof alone. Most repairs are made to the flat roof waterproofing system rather than the roof itself.
6. Easy Installation
Sealing a flat roof takes about a third of the time it takes to replace one. Because waterproofing is a spray applied to your roof, it can get in those hard-to-reach spaces that one-time roof repairs may miss. Waterproofing solutions minimize disruption to your day-to-day business operations, so your employees can stay productive and on schedule.

How To Seal a Flat Roof
If you’re interested in applying a flat roof waterproofing system yourself, there are many steps you must take before and during the application. When waterproofing your flat roof, you need to:
- Keep a close eye on the weather. There should be no rain for at least 48 hours following your waterproofing, and temperatures should remain above 55 degrees Fahrenheit at all times.
- Remove any standing water from the roof surface.
- Locate and seal any holes, punctures, or tears. Be sure you’re using a caulk that adheres to rubber rainproof roofing membranes.
- Remove any asphalt patches or old caulking and refill them with ample amounts of roofer’s caulk. If you have substantial tears or loose seams, butyl roofing tape is the best option.
- Remove all dirt, leaves, and other debris from the roof.
- Thoroughly clean the roof with a mildewcide, soapy water, and a stiff-bristled brush.
- Allow the roof to dry completely.
Once you’ve completed the preparation steps, you’re ready to apply the waterproofing layer and seal your flat roof to add an effective layer of rain, snow, and ice protection.
- Start by mixing the waterproof roof coating according to the manufacturer’s instructions.
- Use a paintbrush to apply the waterproofing material in areas that a roller or push brush won’t reach.
- Next, pour the watertight roofing sealant directly on the roof and spread it evenly, paying close attention to the manufacturer’s suggestions.
- Repeat the previous step until the roof is entirely covered and let the sealant dry before allowing anyone on the roof.
As you can see, applying a flat roof waterproofing system to a commercial roof is no simple task. That’s why many building owners choose to work with a professional roofing company that knows how to seal a flat roof. In many instances, roofing companies apply watertight roofing cheaper and more effectively than a DIY project.
Roof Waterproofing Repair
Flat roof waterproofing systems are designed to be highly durable and add significant protection and longevity, but they’re not indestructible. Severe weather, downed limbs, or abnormal usage can cause damage that requires repair.
Depending on the severity of the damage, roof waterproofing repairs range from basic patches to complete replacements. A thorough inspection performed by a roofing expert is sure to give you the insights necessary to decide the best course of action for a damaged flat roof waterproofing system.
Protect Your Watertight Roofing With Preventative Maintenance
Commercial roofing is one of the most significant investments you can make for your business. To ensure you get the greatest return on your investment, you need ongoing maintenance for your roofing system.
Maintaining your roof is a year-round duty. After waterproofing your roof, sign up for a preventative maintenance contract to keep your roof in excellent condition. Roofing experts agree that your commercial roof should have a professional on it at least twice a year.
Minnesota receives almost double the national average of snowfall each year. Before the weather turns frigid, a maintenance visit in the fall provides snow and ice protection from the bitterly cold winter. Snow removal services and follow-up maintenance visits in the fall and winter pinpoint any issues and fix them before the summer heat and humidity, keeping your roof at its best. Depending on the age of your roof and its condition, you may want to consider more frequent inspections and maintenance.
