Improper Drainage

Commercial buildings typically require special drainage solutions due to their flat or low-sloped roofs. Rather than relying on gravity as pitched roofs do, commercial roofs require scuppers and interior drains to collect rainwater. If the drainage system is poorly designed, poorly installed, or simply clogged, the weight of collected water can quickly overload the weight capacity, leading to backlog and collapse. Water collection, or ponding, may also develop in areas of the roof that are too flat for positive drainage or where a depression has formed. This will lead to a compression of insulation, sinking of materials, and creation of low points, all of which are likely to lead to water getting in your building. 

Membrane Damage

Damage to roofing membranes ranks high on the list of common sources of commercial leaks. The membrane is an integral part of your commercial roof, designed to prevent water from reaching the building’s interior by helping seal and waterproof flat roofs. However, as the roofing membrane ages or inclement weather conditions occur, the membrane can become damaged. When this happens, you may see your roof’s membrane start to crack, split, blister, shrink, or puncture, giving way to the insulation beneath. Equally important is the flashing, or protector of the edges of the membrane, which can become loose during storms or expand and contract as a result of changes in temperature, leading to gaps and leaks.

Open Penetrations

Roof penetrations are found on the majority of flat commercial roofs and can include HVAC units, vents, pipes, hot stacks, gas lines, and any other systems that come through the roof membrane. Any and all roof penetrations are prone to leaks and should be properly sealed to ensure the roofing system is protected from water damage. This includes making sure each of the penetrations is kept watertight with field wraps, flashing, pipe boots, rain collars, or pitch pans. The more roof penetrations you have, the greater the likelihood of your commercial building experiencing a leak. It is important to avoid unnecessary penetration to the roof membrane as well as penetrations placed so closely together that they cannot be individually flashed.

Roof Nearing the End of Its Lifespan

Even if all other major problems on this list have been avoided, no commercial roof will last forever. You may begin to experience rapid deterioration, especially if your flat roof is fifteen to twenty years past its initial installation. It’s time to consult with one of the top commercial roofing companies in Tampa regarding whether or not you should opt for roof repair or preservation to extend the lifespan of your roof or invest in a roof replacement. Aderhold Roofing will address the needs of your business alongside your budget, conduct a thorough onsite inspection, and determine which roofing option is right for you. If you opt for a roof replacement, we will move to implement preservation measures for your investment, such as annual or semiannual inspections. Whether you’re in need of a total replacement or simple maintenance, our licensed roofing professionals are here to help.

The Hidden Dangers of a Leaky Roof

The rainy season in Central Florida runs through late May into mid-October and is characterized by thunderstorms that slowly build during the heat of the day to deliver brief but heavy rainfall. Over half of The Sunshine State’s annual rainfall is received during these five months, and while it may provide an excellent opportunity to enjoy indoor activities, the rainy season can lead to serious damage for your commercial roof.

Our team of licensed and insured roof coating contractors in Tampa with Aderhold Roofing is dedicated to combating high humidity, sunlight, and heavy rain through regular maintenance. Keep your property dry and structurally sound by consulting with a trustworthy commercial roofing contractor ready to serve your needs and extend the lifespan of your roof.

Mold and Mildew

One of the most serious, unseen dangers of a leaky roof is mold and mildew growth. Mold and mildew can begin to develop within just a couple of days of water entering your property. Any area within the building that has a buildup of moisture is likely to experience mold and mildew capable of spreading throughout the building via the HVAC system to the walls, floor, carpets, and wood framing. Not only will you need professional assistance to remove the existing mold spores and restore the condition of the property, but mold and mildew can lead to serious health issues. 

Mold and mildew can lead to the exacerbation of respiratory conditions, such as rhinitis, nasal congestion, and asthma, especially for those with high sensitivity. Additionally, as the mold continues to spread, it can lead to allergic reactions, fungal infections, fever, and shortness of breath. Prevent costly damages and potential health concerns through routine maintenance and inspection for water damage. With the exception of moisture buildup, ventilation and humidity levels are the largest contributors to the spread of mold. If you want to prevent roof leaks in Tampa, you need to contact an experienced, licensed roofing contractor.

Structural Damage

Compromised structural integrity is yet another inevitable consequence of a long-standing leaky roof. First, the wooden components of your roofing system will become deteriorated through water intrusion, leading to sagging, bowing, rotting, and more. If water leaks down into the ceiling joints and wall framing, the costs will continue to steadily rise. Finally, you’ll observe interior damage, such as deteriorated ceilings, buckled wall coverings, and peeling paint. If the leaks are not detected while they are still manageable, then the ceiling could give way and collapse, damaging anything underneath. 

If you’re experiencing leaks on your commercial or multifamily property, it could be traced back to one or more of the following issues: 

  • Clogged drain
  • Blisters
  • Damaged flashing
  • Alligatoring
  • Damaged roof membrane

To address these deficiencies and avoid the hidden dangers of a leaky roof, contact Aderhold Roofing about roof waterproofing in Tampa. We are prepared to trace and stop leaks before they even begin.

What Water Spots on the Ceiling Mean for Your Commercial Roof

Water stains may take a while to notice, but you can’t stop noticing them once you do. Water stains and spots are telltale signs of a leak and a sign that there may be something terribly wrong with your roof. A leak will be a particular challenge to repair if it’s coming from a flat commercial roof — it’s not like they can just replace a few shingles. Fortunately, Aderhold Roofing is here to help

In this brief article, we discuss what water stains mean for commercial roofs and what owners can do to mitigate damage caused by these eyesores. Although your first inclination may be to simply ignore a commercial roof leak in Tampa, doing so could result in extensive roof and structural damage. Always call a professional roofer who can get to the bottom of that dark stain on your ceiling. 

Where Do Water Stains Come From? 

Water travels down the path of least resistance, meaning that the source of your water stain may be hard to find or nowhere near the stain. It also means that the extent of the damage will be difficult to determine at first glance. Maybe the water stain was caused by a recent leak brought on by Florida weather, or maybe it was caused by an ongoing leak that’s only just causing a water stain (one of the many reasons we suggest investing in a maintenance plan to prevent roof leaks in Tampa). 

Although a water stain is usually a sign of a leaky roof, it could really be anything. HVAC units, plumbing leaks, and condensation are only a few potential sources of a leak. Even poorly installed window frames could be the problem. There’s no way of telling where your water stain is coming from until you call upon a professional to take a look at your roof. 

What Commercial Roof Owners Should Do to Mitigate Damage 

You can only replace so many stained ceiling tiles. Blotting, cleaning, and painting over a water stain can help mitigate damage in the interim, but the longer you wait to address the underlying problem the more expensive the repair bill will be in the end. A professional roofer can not only discover the source of the water stain but also provide an appropriate solution, whether that means installing a new waterproof membrane or applying a restorative coating over your existing commercial roof.

Under a maintenance plan, our technicians perform regular inspections to assess the condition of commercial roofs, down to pulling roofing permit history to accurately determine a roof’s lifespan.

Thermal Imaging Capabilities in Roofing

When most people think of the term “thermal imaging,” the first thing that comes to mind is probably how the technology is depicted in movies like Predator. Although some movie magic and special effects may have popularized the technology, the truth is that thermal imaging capabilities can save your commercial roof by uncovering issues impossible to see with the naked eye. A roofing contractor in Tampa will explain more. 

What is Thermal Imaging Technology?

On the surface, your commercial roof may look perfectly fine. However, many building owners will be surprised to learn that their great looking roof actually has some minor leaks. Of course, leaks lead to mold and eventually structural damage. Fortunately, with the right technology at their fingertips, a commercial roofing contractor can utilize thermal imaging to inspect the entire roof system, including what’s underneath the surface. 


There’s a common misconception that thermal imaging is the process of taking temperature readings. According to, the helpful tool actually “detects infrared energy and converts it into an electronic signal, which is then processed to produce a thermal image on a video monitor and perform temperature calculations.” In layman’s terms, heat gives off infrared light and the more heat that collects in an area, the brighter the area will appear on the video screen. Roofing contractors can utilize this technology to determine the difference between wet and dry areas of roofing material.

The Benefits of Thermal Imaging in Roofing

Thermal imaging capabilities allow commercial roofers to inspect roofing conditions more accurately and detect moisture under the roof system. This technology is noninvasive, allowing roofing contractors to detect moisture without a need to cut into the roof membrane. Thermal imaging can be used during all phases of a roof’s lifespan too. The technology can be utilized at the end of the construction phase to ensure that no water entered the roof system during the building process, or it can be used during inspections to pinpoint the location of a leak or wet insulation. 


Although the technology has been around for some time, it’s become easily accessible today with a variety of state-of-the-art camera models that can detect infrared radiation. For example, aerial photography using drones can capture the entire roof system in one shot as the bird’s eye view allows the contractor to see the entire roof’s surface. 


There are many benefits to investing in a commercial roofer that utilizes thermal imaging. The technology can save the owner thousands of dollars when hidden issues are detected and quickly repaired before the roof experiences significant damage. The inspection process also provides the owner with a clear picture of what exactly needs to be repaired on a roof system. 


If you are interested in learning more about this extremely valuable tool and our inspection process, or if you are looking for a company that can maintain and repair your commercial roof system in Tampa, contact the commercial roofing professionals at Aderhold Roofing today.

Why You Should Repair Your Roof Before the Rainy Season Hits

Home to the thunderstorm capital of the United States, Florida is known for its heavy rains, harsh winds, and violent storms. This year will prove to be no different. In fact, 2020 is shaping up to have an above-average Atlantic hurricane season. Considering that this year’s rainy season has only just begun, it’s imperative that multifamily and commercial roof owners take steps to ensure that their roofs will be able to withstand everything that mother nature can throw at them in the coming months. Here’s why it’s so important to invest in commercial roofing repair in Tampa before your roof is hit with heavy rains. 

A Small Leak Now Can Be a Big Problem Later 

The biggest reason to reach out to a roofing contractor in Tampa before the rainy season to repair minor damage in the present so that you can avoid costly repairs in the future. A missing shingle or series of cracks in your roof may not seem like much now, but in a few months, a small leak can cause tremendous damage, even structural damage. Is your roof ready for months of heavy rain? If not, you should get in contact with a roofing contractor in Tampa right away. 

The Rainy Season Makes Repairs Difficult 

Another concern is the logistics of performing roof repairs during the rainy season. Although roofing companies would be more than happy to repair your roof at any time, roof repairs often require days of clear skies — a rare occurrence once the rainy season is in full force. Furthermore, once the rainy season hits, companies like ours are often booked solid with emergency roof repairs. Although Aderhold Roofing strives to assist every client in any way we can, commercial roofing repair in Tampa is best performed long before storm clouds have formed overhead. 

A Roofing Company You Can Trust Year Round 

Although 2020 is shaping up to be a rough year with regards to Florida weather, we’re confident that we can provide the roofing services needed to safeguard your roof against the rainy season. If you’re seeking roof repair, replacement, recover, or restoration services, we encourage you to contact a roofing contractor in Tampa from Aderhold Roofing at your earliest convenience. We further encourage you to invest in a roofing maintenance program offered by us to ensure that your roof is protected year round. Don’t wait for the next thunderstorm to surprise you with a leak. Contact Aderhold Roofing to begin the process of inspecting and, if need be, repairing your multifamily or commercial roof.

Roof Restoration vs. Replacement

If your roof is looking worn, suffering from damages such as missing shingles, or nearing the tail end of its expected lifespan, it’s time for you to consider commercial roof repair in Tampa. Aderhold Roofing is a licensed, vendor-certified roofing contractor that specializes in a number of services from roof replacement and new construction to roof restoration and roof recover. In this brief article, we cover the differences between roof restoration and roof replacement, and how you can decide which option is best for you.

Roof Restoration

Roof restoration is an attractive option for multifamily and commercial projects in which there may not be the budget for a complete roof replacement. There are many benefits to roof restoration over roof replacement, such as lower cost and more sustainability. Not only does roof restoration prevent roofing waste from ending up in landfills, it can also make the property more energy efficient through the use of roof coatings. Restoration coatings are highly reflective, allowing for a drastic decrease in the temperature of the underlying roof substrate and, thus, a reduction in HVAC loads. 

However, roof restoration is not fit for every roof. In order to determine if your roof is a good candidate for restoration, a thorough inspection must be conducted of the overall condition of the roof. There should be no moisture, decay, missing or cracked shingles, or damaged flashing. In order for the restoration to take place, there must be no moisture in the deck or insulation. A simple visual inspection will reveal the first signs of moisture, such as pools of standing water or wet insulation.

Roof Replacement

Roof replacement, on the other hand, is a necessity for roofs that are not candidates for restoration. It’s important to plan your roof replacement in advance rather than waiting until your roof is nearing the end of its lifespan. If you wait too long to obtain commercial roofing in Tampa, it could leave you with costly damages. The process of roof replacement involves either stripping all of the shingles before replacing the underlayment and shingles or layering a new set of shingles on top of the first.

Although a full replacement costs more and takes longer than roof restoration, it is the best option for roofs with extreme or irreversible damage. Additionally, a new roof will ensure the protection of the property for much longer than restoration as well as add value to the property. 

At Aderhold Roofing, a licensed roofing contractor dedicated to commercial roofing in Tampa, we understand that each building is different and your roofing solution must be catered to its unique characteristics and your budget.

Maintaining Your Commercial TPO Roofing System

Maintaining Your Commercial TPO Roofing System

If you do not know a TPO roof from a gingerbread house, you may be missing out on a great solution to Tampa’s tremendous heat and blazing sun.

Thermoplastic polyolefin (TPO) is a single-ply, highly reflective membrane. A TPO roof is an increasingly popular choice for commercial roof installations because of its resistance to heat, its resistance to chemical degradation from ultraviolet light (UV), and its easy workability.

A Typical TPO Roof

A TPO roof is made from polyprophylene and ethylene-propylene rubber. These two chemicals are polymerized into a single mixture, together with fillers like talc, carbon or fiberglass. The typical Tampa TPO roof is notable for its durability and water resistance.

According to experts at, TPO combines the best property of EPDM roof membranes —  durability — with the fast installation technology of hot-air weldable seams. This leaves the TPO roof with seams three to four times stronger than EPDM. It also lowers installation costs to building owners, since the material can be worked on site with the same water-resistant results expected in a custom single-ply PVC roof.

How is a TPO Roof Installed?

A professional Tampa roofer will install a TPO roof in one of two ways:

  1. A fully adhered system
  2. A mechanically attached system

Either method allows the white, light gray or black membrane to stay exposed throughout the life of the roof.

TPO: The Popular Option

Most TPO roofs capture all the advantages of PVC roofs without the higher costs associated with extremely long-wearing PVC. Since TPO is installed and seamed on site, the custom-fitting and higher costs associated with factory-seamed single PVC membrane roofs are not factors.

Another great advantage of white TPO roofing, especially in Tampa’s hot climate, is its energy efficiency. A white TPO roof will reflect infrared (heat) radiation back into the environment, instead of allowing it to enter your commercial building. It means your HVAC system will not have to work as hard to keep your building cool and comfortable.

Make It Last

To make your TPO roofing last as long as possible, develop a plan with your commercial roofer to include:

  • Annual inspection and repair to prevent leaks
  • Roof preservation to maximize your capital investment
  • Quick emergency service, should a leak develop

For a superior roof for your Tampa business, please consider Aderhold Roofing Corporation, your partner in perfect roofs. Contact us today to learn how TPO roofing can be an advantage to your Tampa business, financially, structurally, and environmentally.


3 Ways Florida Weather Wears At Your Flat Roof

Effective roof maintenance is key to preventing Florida’s worst weather from affecting your flat roof.

Tampa’s climate combines at least three roof-destroying forces: wind, rain, and sun. Your local commercial roofer can work with you to schedule a program of roof maintenance to counter this one-two-three punch.

One: Wind

Scouring comes from a prevailing wind pattern, blowing small bits of sand and debris across your commercial roof. Without healthy roof maintenance, this persistent pattern will eat away at single-ply membrane, ballasted roofs, or built-up roofing (BUR).

Annual or even semiannual cleaning, as part of a program of roof maintenance, can eliminate some of the material tossed around like sandpaper against your roof. We do not recommend attempting to clean your commercial roof by yourself, or with your maintenance crew. It takes a trained roofing specialist to safely and effectively clean a roof without damaging it.

Extremely high winds, such as the forces felt in hurricanes, can cause serious damage:

  • Winds can open seams
  • High winds can create a pressure differential to make an entire roof lift from its fasteners
  • Winds can drive water under flashings, around HVAC curbs, and into seams
  • Wind can lift up and tear away TPO membrane or large sections of modified bitumen roofing

Two: Rain

Tampa gets 50 inches of rain annually, according to Sperling’s Best Places. That is nearly a foot more than the U.S. average. It does not all fall in hurricanes, either. One way rain can start to deteriorate flat roofs is through ponding. Rooftop insulation becomes compressed, the roof sags, and water collects. Eventually, water will infiltrate, or plants can take root.

The antidote to rain damage is roof maintenance. Have your commercial roofer inspect seams and parapets to confirm no water can infiltrate before a heavy rain occurs. If the rain has already passed, have them inspect the same areas to see if water is ponding or cannot shed from your roof properly.

Three: Sun

Tampa’s near-tropical sunlight hits at a high angle (more directly) for more of the year than much of the rest of the U.S. This means long periods of ultraviolet (UV) exposure and a lot of infrared (heat) radiation soaking into your roof.

Choosing a bright color for your flat roof will cut down on heat absorption; choosing strong, UV-resistant membranes like TPO or PVC will delay UV damage.

Prevent the worst damage weather can cause to your flat roof. Contract with the professionals of Aderhold Roofing for an effective, affordable roof maintenance program to keep up against the onslaught of wind, rain and sun. Contact Aderhold Roofing today to get a site visit from a trained professional.


Proper Planning Can Prevent Emergency Roof Repair

You no doubt have seen the sign in businesses like copy centers and freight shipping offices: “Lack of planning on your part does not constitute an emergency on my part.”

It is a favorite among folks who serve an often-anxious public, but it applies equally well to commercial roofers dealing with those frantic calls from commercial building owners.

Plan to Fail?

Another aphorism (perhaps from Ben Franklin, no less) says if you fail to plan, you are planning to fail. This is especially true of your low-slope or “flat” roof, which literally shelters the rest of your entire business. Consider what goes on under that roof:

  • Building supplies that must stay dry to be usable
  • Residential buildings with finicky tenants inside
  • Hospitals and nursing homes with frail residents
  • Businesses catering to customer foot traffic

Without roof preservation, you are risking a roof leak that could shutter your business while repairs are made. No customers. Moving patients, or paying tenants to stay at expensive hotels and motels. Ruined inventory; the list is nearly endless.

Roof Preservation

The logical alternative to disrupting your commercial building’s occupants with emergency roof repair is roof preservation. Plan a regular schedule with your local roofer. Set up inspections, routine repair work, and systematic cleaning.

With roof preservation, you lessen the chances that an unexpected leak will appear to ruin inventory or tenants’ possessions. Roof preservation lengthens the life of your roof, too, with protective coatings.

When you partner with a local, reliable roofer, you get a crew that becomes familiar with your company’s individual low-slope roof. Careful documentation can help crews focus on problem areas like flashing, degraded internal drains, or loose mechanical fasteners.

Tampa Weather

Roof preservation is also your protection against Tampa’s harshest weather. From hurricanes to blistering heat, Tampa’s climate taxes even the best commercial roof. With roof preservation services from Aderhold Roofing, you can be prepared for the next Category 5 or the next heat wave. Roof preservation also makes storm repair work easier, faster to fix, and less expensive.

Aderhold Roofing is ready to help with emergency roof repair, but we also can be your partner for long-term roofing maintenance and roof preservation. Contact us today to see how our extensive program of roof preservation can help you properly plan to avoid roofing emergencies. Our trained crews can monitor and protect your roof year-round and respond to storm damage when needed.


Vital Elements Connected To Flat Roof Functionality

Any of Tampa’s amazing physical therapists will tell you that your body is a finely tuned, balanced system. When one little part — your lower back, an ankle, or a hamstring — goes out, your whole body gets out of whack. The same is true of your commercial flat roof. It is an integrated system of many interconnected parts, and each part has a role to play in keeping your Tampa business dry, climate-controlled, and safe.

S is for Scuppers

The parapet scuppers (those openings that allow water to drain off your not-quite-flat roof) must be kept clear and free-flowing, so Tampa’s strong storms do not overwhelm your roof.

Scuppers and internal drains allow wastewater to flow quickly off the roof and away from your building’s foundations. This has several positive effects:

  • Foundations stay dry, tight and strong
  • Roof surfaces dry quickly
  • Water has no time to pond

Clean scuppers are key to keeping your commercial building dry and at the ideal humidity.

S is Also for Seams

If your roofing material has seams, you have only two options for keeping them sealed:

  1. Heat — Heat-sealed seams are strong, waterproof, and long-lasting if done correctly; deferred maintenance or poor installation workmanship can spell trouble
  2. Chemicals — Adhesives will hold the seams together only if the correct adhesive, specific for the roofing material, is used

Increased interior humidity and higher energy bills are typical problems rooted in open seams.

B is for Built-Up Roofing

One of the longest-lasting and economical roofing solutions for many Tampa commercial properties is built-up roofing (BUR). Unlike a PVC membrane, BUR is itself an integrated system of layers. Therefore, BUR requires some special care.

Experts at Facilities Net identify several common problems a strong commercial roofer will spot (and solve) quickly:

  • Alligatoring — When the asphalt used in the various layers begins to shrink, alligatoring (crazing) can occur; as these worsen, splits in membrane can cause water leaks
  • Blisters — Trapped moisture beneath the top surface causes blisters; remove the moisture and the blisters can be patched
  • Ridges — Damaged insulation below the BUR layers can separate from those layers, which expand and contract with Tampa’s volatile temperatures
