Commercial Flat Roofs: 5 Tricks to Stop Water Ponding

Water ponding can be a problem for commercial flat roofs. Standing water can attract insects, lead to mold and algae growth, and create interior leaks. It can accelerate the deterioration of the roofing materials, reducing the longevity of the roof. Ponding can also invalidate roofing warranties and compromise your building’s structural integrity.

commercial roof maintenance

Fortunately, professional roofing contractors have workable solutions for eliminating or preventing water pooling on commercial flat roofs.

No. 1: Fix Low Spots

Despite the common perception to the contrary, commercial flat roofs aren’t completely flat. They have subtle slopes to facilitate drainage. If your rooftop has low spots, water ponding can easily occur. A professional roofing contractor can fill in low areas with roof plaster to better direct water toward drains.

No. 2: Flush Existing Drains

Just like the drains in your home, the drains on commercial roofs can become clogged with debris. In some cases, a serious clog can lead to standing water. Removing leaves, sticks and other rooftop debris from the drainage system is frequently sufficient to allow rain and melting snow to flow away as it should.

No. 3: Add More Drain Lines

Flat roofs in areas with high precipitation often need additional drains — a fact the building owner may not realize until water ponding becomes a problem after a heavy storm. Professional roofing contractors can install extra drain lines or widen the existing drains to direct water away from the rooftop.

No. 4: Install Roof Crickets

Water ponding near chimneys and large vents can often be solved by installing roof crickets. Crickets are ridged structures designed to divert rainwater and melted snow around roofing obstructions. Adding crickets can also help when standing water is associated with a transition between roof areas.

No. 5: Re-Pitch the Rooftop

With some commercial roofs, the pitch wasn’t properly designed or installed the first time around. Without adequate sloping, water can’t drain and pooling is likely to occur. Though the process is complicated and may be costly, re-pitching a flat roof is sometimes the only way to solve a ponding problem.

Have you noticed standing water on your building’s roof, or do you want to make sure that water ponding doesn’t become a problem? Either way, the professional roofing contractors at Knockout Roofing can meet your needs.

When You Replace a Roof, Should You Replace the Skylights Too?

So you’ve decided now’s the time to replace your roof — and the local roofing contractors are urging you to replace your skylights at the same time.

Replace a roof, should you replace the skylights too?

Is that really necessary? Or are these roofers trying to pull a fast one?

The truth is that any reputable, experienced roofing contractor will recommend skylight replacement at the same time you do your roof replacement. You don’t have to agree, but if you replace your roof without replacing your skylights, you may come to regret the choice later when you discover a leak — which happens in many (but not all) cases.

Some Skylights Can Survive a Roof Replacement

There’s always a chance your skylights could survive a roof replacement. If they are non-opening, less than 10 years old, from a top manufacturer and designed and installed as part of a new home construction, they may not leak after the roofing is replaced.

Unfortunately, this perfect set of conditions almost never exists.

You won’t typically need to replace your roof until it begins to have structural problems. And with a new home, that generally doesn’t occur for at least 20 years. By that time, the skylights are way past their 10th birthday, so the likelihood of them making it through a roof replacement unscathed is pretty low.

Why You Might Want to Replace the Skylights When You Replace the Roof

Why do skylights leak after roof replacement?

Simply put, the roofing tear-off can compromise their integrity. Even an experienced, highly skilled professional roofer can’t avoid disrupting skylights when tearing off an old roof.

Skylights have several seal points that can easily be disturbed enough to allow moisture to get inside. Adding new caulking and flashing can help, but once a skylight seal has been compromised, repairs are typically not effective against future roof leaks.

Replacing Skylights After Roof Replacement Can Create Further Problems

You could still decide to take your chances and skip skylight replacement for now. But if you go that route and your skylights leak a year or two later, you may face further roofing problems.

Replacing your skylights at this point will disturb your new roofing system. Just as a roof tear-off can blow the seals of a skylight, a skylight replacement can create similar issues with a roofing system.

So while your roof replacement project may come in at a lower cost if you decide against skylight replacement, you could end up paying a bigger price later when the integrity of your new roofing system is compromised.

Do you have questions about skylight or roof replacement? The professionals at Knockout Roofing, serving clients throughout northern Utah for over 15 years, offer expert answers and advice.

As the region’s leading roofing contractors, the Knockout Roofing team is known for exceptional service, superior workmanship and affordable prices.

7 Residential Roofing System Performance Threats

When choosing a new residential roofing system, most homeowners tend to rank function above form. Aesthetics and architectural style are important, but customers naturally want their new roof to last as long as possible.

Residential Roofing System Performance Threats

A professional roofer can recommend high-quality, durable rooftop materials capable of protecting your home for decades. However, roofs do have a few natural enemies. Below are the top seven threats that can compromise your residential roofing system’s performance.


How much sunshine hits your rooftop each day? Over time, heat and ultraviolet rays can cause roofing materials to deteriorate. The effect on system performance is typically worse on roof surfaces that face west or south.


When rainwater gets underneath a roof, the support structure can begin to rot. The extra moisture also encourages the growth of mold and mildew within the roofing material, which can spread to the interior walls and ceilings.

Heavy Wind

High winds can lift the edges of a rooftop, blowing away shingles and allowing water and debris to work their way into the roof system. Extremely heavy wind can create extensive damage to most types of roofing materials.

Snow and Ice

As snow melts, it can refreeze at the rooftop’s edge, where the surface is cooler. This causes an ice dam to form, which can block the gutters and drainage system, which can, in turn, create irreparable damage. In addition, ice dams allow water to back up under the roofing materials, which leads to roof leaks and deterioration.

Moss and Algae

When some types of roofing materials become moist, moss and algae can grow. Not only is this growth unsightly, it also leads to roof leaks and the development of mold and mildew.

Poor Ventilation

Ventilation has a profound effect on your roofing system’s performance. In a poorly ventilated attic, condensation builds up inside and underneath the roofing materials. If the problem isn’t quickly addressed, the roof structure can deteriorate.

Overhanging Tree Branches

Trees may not seem all that threatening to your roof’s performance, but overhanging branches can cause trouble. Tree limbs can scrape and gouge roofing materials when the wind blows, and falling branches can create significant damage. Fallen leaves can block drainage systems or stick to the roof and promote rot.

So which type of residential roof system will perform best for your northern Utah home? A professional roofing contractor such as Knockout Roofing can help you make an informed choice, based on your needs and budget.

For more than 15 years, we’ve been providing residential and commercial roof repair, installation and maintenance services in Salt Lake City and the surrounding communities. The Knockout Roofing team has a reputation for high-quality work, exceptional customer service and affordable rates.

Roof Replacement Preparation Tips for Homeowners

Roof replacement is a major home improvement project that can take anywhere from a few days to a few weeks.

roof replacement preparation tips for homeowners

A bit of preparation can go a long way toward making sure your re-roofing goes as smoothly as possible. We’ve put together some helpful homeowner tips to help you get your house ready for roof replacement.

Make Sure the Roof Is Easily Accessible

A home re-roofing project requires heavy equipment, ladders, tools and roofing materials. And all these items need to be close to or on top of your roof.

Before the roofers show up to begin work, make sure vehicles, trash cans and toys are out of the way. Clear the area so that the contractors can move the trucks in closer and have easier access to your rooftop.

Mark Off Fragile Landscape Features

Experienced professional roofers always try to avoid shrubs, trees, lawn decorations, sprinkler head and other landscape features. But damage can occur during a home roof replacement project.

To greatly reduce the chance of that happening during your re-roofing, grab some small flags at your local home improvement store and mark off any delicate landscape features.

Get the Inside of Your Home Ready

A roof replacement project doesn’t just affect the outside of your home — the work may create vibrations inside your house.

If you have any keepsakes, furniture or important items stored in the attic, you may want to move them or use a cover to shield them from dust and debris. Also, consider removing wall art and fragile decorative accessories until the re-roofing is completed.

Make a Plan for Kids and Pets

You’ll need to keep your kids and pets away from the worksite. Children should stay inside or play in an outdoor area far from the house. The same goes for pets — if Fido needs to go outside, keep him on a leash or in a fenced-off part of the lawn.

In addition, re-roofing can be noisy. If you have a nervous dog that barks at every sound, you might want to make arrangements for them to spend time elsewhere.

Re-roofing can protect your home and increase the value of your property — if the job is done properly. Hire the Knockout Roofing team, and you can count on high-quality workmanship and exceptional customer service at an affordable price.

With more than 15 years of experience providing re-roofing, roof repair and rooftop maintenance services to homeowners throughout northern Utah, Knockout Roofing is the region’s leading local professional roofer.

Prevent Roof Rot with These 6 Tips

Roof rot can create serious structural integrity problems. When dry rot begins to eat away at a rooftop, the wooden supports and materials become weak and crumbly. Left untreated, the roof can leak or even collapse. Plus, rotting leads to mold growth, which can threaten the health of your family.

Prevent Roof Rot with These 6 Tips

To prevent roof rot, you’ll need to take proper care of your home and rooftop. What should you do?

No. 1: Schedule Regular Roof Inspections

Have a professional roofer come out and inspect your roof at least once per year — twice is better. Regular roof inspections can identify and resolve issues that could lead to rotting, so that roof rot can’t take hold.

No. 2: Install an Effective Roof Ventilation System

Your attic needs to be properly vented so that the air flows freely and moisture can escape. To prevent roof rot, make sure that you have an effective ventilation system, with sufficient ridge vents, soffit vents and attic fans.

No. 3: Keep the Gutters Clear

Excessive rooftop moisture can cause rotting — and clogged gutters can trap water right at the roof’s edge. Clear your gutters and downspouts regularly to help ward off roof rot. You might also want to have gutter guards installed to keep your gutters clog-free.

No. 4: Remove Debris Immediately

Leaves, tree branches and other debris can block rainwater and melting snow from flowing off the roof. Standing water is more likely to cause rot, so make sure to remove any debris from your rooftop as soon as possible.

No. 5: Replace Missing or Damaged Shingles Promptly

Cracked or loose shingles can compromise your roof and leave it at risk for rotting. Replace any missing or damaged roof shingles as you notice them to prevent rooftop rot from becoming a problem.

No. 6: Pay Attention to Attic Temperature

The temperature in your attic needs to remain moderate all year long to help prevent moisture from building up. To keep the level consistent and prevent roof rot, you may need to install a fan, heater or air conditioner. For some attics, a dehumidifier can also be helpful.

Is it time for your annual roof inspection, or do you think your roofing could be rotting? If so, Knockout Roofing can help. Serving clients throughout northern Utah area for more than 15 years, we can handle all your rooftop maintenance, repair and replacement needs.

Is Roof Repair Possible in the Winter?

From early spring to late fall, roof repair crews can be seen at homes throughout northern Utah. Once winter comes, however, you don’t see too many roofers at work. Does that mean roofing isn’t possible at this time of year?

Roof Repair 

Not at all. While rooftop work is more dangerous in snowy and icy conditions, experienced roofers — such as the professionals on the Knockout Roofing team — absolutely can complete a roof repair in the winter. If your roof springs a leak or becomes damaged, you won’t have to wait until spring to preserve the integrity of your home.

However, before scheduling the repair, professional local roofers will consider a few factors.

Is the Roof Repair Necessary Now?

Many roof problems should be addressed as soon as possible in order to prevent the damage from worsening. Roof leaks, damaged underlayment and missing shingles are examples of issues that need immediate attention.

With some minor roofing problems — such as shingle blistering or granule loss — the situation may not be quite as dire.

When scheduling a wintertime roof repair, professional roofers take the severity of the problem into consideration. Urgent issues are prioritized, but due to the potential danger of roof work in the winter months, less critical fixes are often better left for early spring.

Are the Conditions Safe for Roof Repair?

Before coming out to complete a repair, professional roofers have to think about the weather. If a snowstorm hits the greater Salt Lake City area or the conditions are particularly icy, roof work may have to wait a day or two.

Preserving the integrity and stability of your roof is crucial — but roofing crews have to stay safe. If weather conditions will put the roofers at a greater risk, repair must be delayed.

Will the Temperature Affect the Roof Repair?

Temperature is also a factor for winter roof repairs — if it’s too cold, rooftop work can be more difficult.

Professional roofers can work in extremely chilly weather, but nail guns often can’t. When the temperature is below freezing, roofing crews may have to turn to hand-nailing — a process that takes longer and adds to the overall repair cost.

In addition, cold temperatures can affect some roofing materials. For instance, certain types of roof shingles may not seal properly until the weather warms up, leaving the roof vulnerable to damage.

Before working on a rooftop in the winter, professional roofers have to consider the temperature and the affect it may have on the repair.

Does your roof need to be repaired now? Don’t wait for spring to arrive, or the problem could get worse. Instead, make an appointment with the professionals at Knockout Roofing, northern Utah’s leading residential and commercial roofing contractor.

The Knockout Roofing team can meet all your roofing needs — even problems that crop up in the middle of winter. Our expert roofers provide top-quality workmanship at an affordable price, and our commitment to customer satisfaction is beyond compare.

New Gutters: What Color Should You Choose?

Are you planning to install new gutters on your northern Utah home? Performance is likely your chief concern, since a properly functioning rain gutter system helps prevent roof leaks and foundation damage. But appearance is also important. Consequently, you want to choose a color that enhances the overall look of your home.

Adding New Gutters

Choosing the right color for your new gutters can seem like a daunting task. To make the decision easier, you can ask yourself a few key questions.

Are Your Gutters Visible from the Curb?

Stand at the curb and check to see if your rain gutter system is visible. If not, the color of your new gutters may not matter quite as much. Keep in mind, though, that a bold or contrasting shade could shine a spotlight on the gutters — which may affect your home’s curb appeal.

Do You Belong to a Homeowners Association?

The color of your gutters may not be entirely up to you. If you belong to a homeowner’s association, you might have to follow certain guidelines regarding the exterior colors of your home. Find out about any restrictions before installing new gutters, or you could find yourself in hot water with your HOA.

What Color Is Your Roof?

Many northern Utah homeowners opt to match their gutters to their roofs. Going with the same color as your roof can be a smart strategy, as it allows the rain gutter system to appear as an extension of the roofline — the gutters really won’t be noticeable at all.

What Color Is Your Home’s Exterior?

Similarly, choosing a color that echoes the shade of your exterior paint or siding will allow your gutters to blend right in. Your rain gutter system won’t call attention to itself — it will be less of a visual feature. For many northern Utah homes, matching the gutters to the exterior color is the best approach.

What Color Is Your Exterior Trim?

Most Utah homeowners match their rain gutter systems to either their rooftops or their exterior walls. But depending upon your home’s style, it could make sense to choose a color that coordinates with the exterior trim. The visual harmony of your home could be improved if your gutters are the same color as the trim around your doors and windows.

If you’re not sure which color to choose for your new gutters, let the professionals at Knockout Roofing help. With over 15 years of experience serving homeowners in northern Utah, our team has what it takes to guide you toward the right decision.

Knockout Roofing is known for stellar customer service, exceptional workmanship and affordable rain gutter system installation. Contact our Salt Lake City office today to schedule a free professional consultation and estimate for your new gutters.

Is a Roof Leak the Cause of Your Ceiling Stain?

A roof leak may be to blame if you notice a mysterious stain on the ceiling.

Although the two are not always related, roof leaks are a common cause of ceiling stains. But leaking isn’t the only roofing problem that creates unsightly water spots. An ice dam or condensation issue could just as easily be the culprit.

Roof Leak

How do you know if your water damage is from a roof leak, another roofing problem or something else? Our layperson’s guide to determining the source of a ceiling stain can help.

Ice Dam

If your ceiling stain is near an exterior wall, you may not have a roof leak — an ice dam is the likely culprit.

Ice dams form after a buildup of snow melts and refreezes on the rooftop. This usually happens as a result of insufficient attic insulation, though poor ventilation and other roofing problems may play a part. An ice dam can be destructive, forcing water through the roof shingles and creating ceiling spots.

Attic Condensation

If you have random spots of water damage with no clear sign of a roof leak, you could have an attic condensation problem.

In attics with tight insulation and few vents to allow moisture to escape, condensation can develop. Eventually, this can trickle down, causing stains.

Exhaust Fan Condensation

If your ceiling stain is near an exhaust fan, chances are the fan is connected to a duct that isn’t properly insulated.

When an exhaust fan duct doesn’t pass through an air-tight, insulated vent in the roof, moisture condenses instead of evaporating into the outside air. When enough moisture is trapped in the vent space, it can run down and create a stain.

Finding the Cause of Your Ceiling Stain

Besides a roof leak, ice dam and condensation issues, a number of other household and roofing problems can produce ceiling stains. Pinpointing the exact cause isn’t always easy.

If you can’t determine the source of your water damage, contact a professional roofer as soon as you notice a ceiling stain. Ceiling spots should never be ignored, as the underlying roofing problem will only get worse.

If you live in northern Utah, the professional team at Knockout Roofing has the skills, knowledge and training to accurately identify ice dams, condensation issues and roof leak problems.

Utah Roof Problems to Watch for this Winter

In Utah, roof problems are common during the winter months. But if you keep your eyes open and catch them early, your home will be better protected against the elements.

Utah Roof Problems to Watch for this Winter

This winter is expected to be colder and snowier than normal for northern Utah, which means many different things can go wrong with your roof. If you notice any of the common roof problems listed below, contact a professional roofer right away.

Ice Dams

Ice dams are among the most damaging roof problems for areas of Utah that get snow and ice.

An ice dam forms when heat collects in the attic space, warming the underside of the roof deck and melting the snow. The water runs down the roof and refreezes at the edge along the gutters. Ice dams can cause the gutters to give way, and they can also create moisture damage inside and outside the home.


Icicles may seem harmless, but they result from the same rooftop conditions as ice dams, and they can be just as destructive.

When large numbers of icicles form in one area, the culprit is usually poor attic insulation in that spot. Not only can icicles destroy gutters, but they can also cause injury to people below if they suddenly break lose.


The cold can also create roof problems that affect the inside of the home.

Condensation can occur due to poor attic ventilation. When the heat inside a home rises to the attic, it can become trapped if the roof doesn’t have enough vents. The moisture in the air condenses on the walls and underneath the roof deck. Over time, condensation can lead to mold, mildew and rotting in the attic and roofing materials.

Heavy Snow

Northern Utah may not see many severe blizzards, but heavy snowfall can cause roof problems.

Though roofing systems are designed to withstand snow loads, the weight of a large amount of snow can create roof damage. In some cases, snowfall can induce or contribute to rooftop collapse.

Tree Limbs

Many Utah homes have large trees with branches that hang over the rooftop. Diseased or stressed limbs can cause serious roof problems.

When branches become burdened with ice and snow, they are more likely to break off and fall. Fallen tree limbs can weaken, crack or break away roofing materials. In addition, branches can trap snow or water on the rooftop, leading to further roof damage.

The professional team at Knockout Roofing, serving customers in northern Utah for over 15 years, is known for providing exceptional workmanship and top-quality roofing materials at an affordable price.

Steep Roof Pitch versus a Low-Slope Design: Which Is Better?

Is roof pitch important when you’re building or buying a home in northern Utah?

A steep roof pitch usually comes at a slightly higher price, due to the additional roofing materials and labor required. However, a steep-slope roof offers several significant advantages.

Steep Roof Pitch versus a Low-Slope Design

Less Pooling Water on the Roof

Water accumulation is bad news for a roof, and it’s a real danger for flat and low-slope roofs. With a high-slope roof, gravity is your friend. Rain and melting snow easily run off, so you don’t have to worry about pooling water degrading the materials and causing a leak.

Less Rooftop Snow Accumulation

Some parts of northern Utah are particularly snowy. In a home with only a slight roof pitch, snowfall can accumulate, leading to destructive ice dams and  moisture infiltration. When snow falls on a steep roof pitch, it slides away before it can build up and cause roofing damage.

Less Debris on the Rooftop

Leaves, pine needles and tree branches that land on a low-slope roof usually stay where they fall. Over time, unless you clear it away, debris can build up and cause roofing problems. With a steep roof pitch, any debris that falls is likely to tumble to the ground quickly.

More Roofing Style Choices

Many homeowners consider flat roof architecture to be visually dull. Flat and low-pitch roofs offer limited design options. High-slope roofing, on the other hand, offers a wide variety of styles and detail options. With gables, dormers and visual architectural details, a steep roof provides for a more interesting look and enhanced curb appeal.

More Attic Space

When you choose a high-slope roof, you get a bonus — plenty of attic space. You can leave the space unfinished and use it for long-term or seasonal storage. Or turn it into a playroom, home office or extra bedroom. A low roof pitch won’t give you much storage space, let alone an extra room.

More Rooftop Durability

Thanks to pooling water and problems with snow and debris accumulation, low-pitch rooftops tend to be less durable than steeper roofs. High-slope roofing typically has a longer life span and needs fewer repairs over time.

One thing to keep in mind is that slope can affect your roofing material choices. Conventional shingles aren’t appropriate for a flat or low roof pitch, for example, and a membrane system won’t work with a high-slope roof.
