What Is Waterproofing?

Commercial roof waterproofing creates watertight, rain-proof roofing that protects your building from the adverse effects of water seepage. A variety of issues cause roof leaks. In Minnesota, you need to protect your roof from the UV light and humidity it’s exposed to during the summer as well as the extreme cold, snow, and ice of winter.

The majority of low slope roofs and roofing materials can be waterproofed, but may require different solutions. That’s why working with an experienced roofing company that knows how to seal a flat roof 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 serious damage. Waterproofing your roof is simpler than a complete roof replacement while still offering many of the same benefits. At the same time, it provides a longer-term solution than a quick-fix 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

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 waterproof membrane reflects sunlight, reducing the impact of extreme heat and light on your roof. Snow and rain-proof roofing 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 roof overhaul and repairs and maintenance won’t be required as frequently. By extending the life of your existing roof with a water-resistant roof coating, you also experience significant cost savings in the long run.

3. Energy efficiency

Because most types of waterproof membranes 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. Watertight roofing reduces the humidity levels in your building while also preventing the growth of mold. You, your employees, and your clients will all be more comfortable, and you’ll be protected from more serious structural issues, like weakened foundation walls.

5. Low maintenance

A waterproof coating is much simpler to maintain and repair 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 will be made to the waterproof coating 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 any downtime or disruption to your day-to-day business operations, meaning your employees can stay productive and on schedule.

How To Seal a Flat Roof

If you’re interested in applying a waterproof roof coating yourself, there are many steps you must take before and during the application. To begin, 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 ponding water.
Locate and seal any holes, punctures, or tears. Be sure you’re using a caulk that adheres to rubber rain-proof 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 seal your flat roof and prevent water from entering your facility.

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 entire roof is entirely covered and let the sealant dry before allowing anyone on the roof.

As you can see, waterproofing 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.

Protect Your Watertight Roofing With Preventative Maintenance

Commercial roofing is one of the most significant investments you can make in your business. To ensure you get the greatest return on your investment, you need to provide your roofing system with ongoing maintenance.

Maintaining your roof is a year-round duty. After waterproofing your roof, signing up for a preventative maintenance contract helps keep your roof in excellent condition. Roofing experts agree that, at a minimum, 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. A maintenance visit in the fall before the weather turns icy, snowy, and bitterly cold will keep your building safe throughout the winter. A follow-up maintenance visit in the fall to pinpoint any issues and fix them before the summer heat and humidity also keeps 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.
