Flat Roof Leaks in Heavy Rain

Commercial Park, Aerial View with Several Large Structures.

A Low-Slope or Flat Roof Is Generally Chosen as an Economical Option for Large Structures.

A flat roof will always represent something of a gamble. While their economy and ability to cover large areas make them ideal for commercial roofing, building owners must practice a lot of oversight to ensure proper flat roof repairs. As a matter of fact, this oversight should ideally begin with the roof’s construction. Since flat roofs will always remain vulnerable to heavy rainfall, there must exist a proper, dependable drainage system. The roof must also have proper grading to prevent ponding, a highly troublesome issue that can become quite difficult to solve.

Homeowners who choose flat roofing tend to do so for aesthetic reasons, rather than economy. If the appearance of a flat roof provides the main justification for its choice, then the homeowner needs to fully understand the roofing’s vulnerabilities. If they do not, they risk a litany of problems that could include leaks with every heavy storm. For residential and commercial properties alike, a flat roof represents a compelling choice. Even though the reasons for this choice are drastically divergent, the responsibility for proper care and awareness remains the same.

Flat Roofing Systems and Rainfall

If you need to choose a new roof for your structure, or purchased a home or business that already had a flat roof, you should fully understand not just the advantages of this roof system, but also its drawbacks. A lack of dependable, functional, and effective drainage represents the main problem with many flat roofs. During and after storms, it can seem as if water simply refuses to leave the roof.

Flat Roof Advantages

  • Economical and Cost-Efficient
  • Rooftop Space for Storage
  • More Interior Space
  • Accessibility for Repairs and Installs

Flat Roof Disadvantages

  • Drainage Difficulties
  • Propensity for Leaks
  • Limited Choice of Roofing Materials
  • Short Lifespan Expectancy

The economy and cost-efficiency of flat roofing provides the top justification for its choice. Flat roofing materials generally cost around 80 cents per foot. This applies not only for installation, but any time new roofing material is needed for repair or maintenance. You should also not underestimate the advantage of a large rooftop storage area. While many companies and homeowners simply use the roof to store HVAC equipment, it can serve a variety of purposes, including space for a rooftop garden, deck, or leisure area, oran ideal expanse for the installation of solar panels. Furthermore, a flat roof makes it possible to take full advantage of your structure’s space, without the frustration of sloped walls created through a pitched roof. The accessibility of a flat roof also matters, as it makes it easier to both identify and make repairs.

As for disadvantages, drainage difficulties are, of course, the number one problem. Even well-designed drainage systems will operate slowly, and allow for the continued threat of ponding. This troublesome issue occurs when a portion of the roof has a lower grade than the surrounding area. While this can happen through faulty construction, it can also occur as a natural consequence of the roof’s age. Regardless of how it occurs, ponding creates the same problems as a place that will attract and trap water. Many people fail to realize the corrosive capabilities of water. As it sits on your roof, water will gradually eat away at seams and other vulnerable areas, and create the likelihood for leaks. Ponding will also grow worse over time, as the weight of the trapped water will continually cause the problematic section to sag further.

Flat Roof Materials

Flat Roofs Can Become Vulnerable to Leaks at Their Seams.

Another disadvantage of flat roofing is the relatively poor choice of available materials. Since economy serves as the primary justification for many flat roofs, many building owners opt for rolled roofing. This category refers to roofing materials that are literally rolled on, then secured through adhesives, heat welding, or weight. Rolled roofing materials include EPDM, TPO, and bitumen. While easy and cheap to install, it’s not uncommon for these materials to last only 10 or 15 years. More durable options do exist, including PVC roofing, but the higher cost can serve as a major drawback when you need to roof a massive commercial warehouse.

Flat Roof Drainage

As discussed above, the lack of natural drainage is a serious drawback for many flat roofs. The precise reasons for this problem are as follows:

  • Ponding water contributes to leaks and overall damage.
  • Windblown debris will simply sit on the roof and trap more moisture.
  • Pooled water and debris will deteriorate caulking and adhesives.
  • Ice and snow become hugely problematic due to weight and drainage difficulties.
  • More likely to have leaks at flashing and other vulnerable areas.

Believe it or not, systems do exist for proper flat roof drainage. If you decide to make the investment in one of these roofing systems, or are forced to choose one out of financial necessity, make sure to fully employ the potential of each of these features.

Interior Drains: These work just like the drain of a shower. A drain is installed in an area that collects water, then sends it out via a system of pipes through the building’s interior and into a downspout.

Gutters: Flat roofs can also use gutters, which will collect water as it drips off the side of a roof, and channel it away from a building’s vulnerable foundation.

Scuppers: A highly effective drainage solution, scuppers are square openings installed along the roof’s perimeter to shoot water away from the building.

Will a Flat Roof Always Leak?

The answer to this question depends on one thing: the quality of the roof’s construction. Flat roofs installed by inexperienced or rushed roofers can very likely have permanent drainage issues. However, if the installation employed a skilled, expert roofer with plenty of experience in flat roofing, then leaks may only rarely develop. This all depends not only on the quality of roofing material installation, but also on the integration of proper drainage opportunities.

Can Flat Roofs Be Repaired

Like any type of roof, flat roofs benefit from regular maintenance and repairs. However, since a selection of problems can create the need for flat roof repairs, you must stay attentive to your roof’s needs. Since a lack of service can cause a flat roof to rapidly break down, preventative repairs provide the secret to long-term value. If you notice any of the following, make sure to call a trusted commercial roofer right away for an inspection.

  • Ponding
  • Rips and Tears in the Roofing Material
  • Mold Growth
  • Broken Flashing
  • Leaks

Common Questions About Flat Roofs

What Are the Different Types of Flat Roofs?

Flat Roof Housing Many HVAC Devices.

Flat Roofs Provide a Convenient Space to Store HVAC Units.

Built Up Roofing (BUR): Also known as tar and gravel roofing, this consists of layers of roofing felt topped with asphalt and gravel for waterproofing and impact protection.

Modified Bitumen: Similar to BUR, but with only two layers of material installed with rollers.

EPDM: Also installed via rollers, this type of roofing either adheres to a substrate, or has ballasting with stones. EPDM roofs are also known as rubber roofs, and appear like one would expect.

SPF Roofing: Spray foam is a seamless type of roofing applied as a liquid. Upon application, this liquid immediately expands and hardens for an airtight seal. It is usually covered with an elastomeric topcoat for added protection.

PVC and TPO: These are both thermoplastic membranes that consist of a single layer. Easy to install, these materials provide a range of benefits that make them a popular choice for flat roofing.

What Are the Problems with Flat Roofs?

Drainage difficulties and susceptibility to heavy rainfall represent the main problems with any type of flat roofing. There are also few choices in roofing materials, compared to the vast selection afforded to peaked roofs.

How Long Should a Flat Roof Last?

This depends on a number of factors, including the material chosen to cover the roof, the quality of its installation, the presence of proper drainage systems, the frequency of maintenance, the environment the roof exists within, and more. As a general rule, a well-maintained commercial roof can last for 20 years.

Do Flat Roofs Leak More?

If equipped with proper drainage systems, including internal drains, gutters, and scuppers, flat roofs leak no more than pitched roofs. If a flat roof lacks proper grading and has a poorly designed drainage system, then it will leak much more frequently than other roofs.

A New Way To Check Roofs Out


Drone In Sky

Have a Drone Check Out Your Roof!

Technology has come a long way in the world and it hasn’t stopped for roofing technology either. Today, we have what are called drones that are able to fly up in the air and look at your roof in a way that even sometimes inspectors cannot do themselves. These little flying machines can do a lot inside of their small frames and they can be an excellent addition to a roofing company. Sometimes roofs have a hard time being accessed or maybe we didn’t bring the right equipment to get up there that day. This is when a drone comes in handy. This can take a look at your TPO roofing before we can even get up there to see it. We also have other great ways to detect leaks without using traditional inspections, like RWS scanners as well.

How It Works

Roof Inspections – These drones can look at your roof from the sky and be able to detect things on your roof without a contractor having to go up there on their own.

Infrared Scans – These scanners can detect roof leaks using infrared technology that even the human eye can’t see.

Leak Detection – If you have a leak and it is on your roof, a drone can look to see where it is so it can be repaired.

Hard To See Places – There are sometimes places that even we cannot see or go to a drone would be able to do that for us.

If you want to know more about drones in Austin, TX, call Dimensional Drones at (512) 402-8877.

How Infrared Scanners Detect More Accurate Roof Leaks

An Infrared Scanner Can See Leaks In Roofs From Situations Like Ice Dam Build Up

If you notice dripping water from your ceiling, you have a major roof leak problem. This could have been prevented with annual roof inspections for your Austin, TX home using an infrared scanner called an RWS scanner. Ordinary roof inspections rely on human eyes and trained professionals to spot hidden leaks under layers of roofing material, but with an RWS scanner, infrared technology can see through the material to find wet spots, guaranteeing a more precise inspection. For more information on how moisture and leaks can be found in walls and roofs during a roof inspection by using a RWS scanner, call Dimensional Drones at (512) 402-8877.

How To Spot a Leak In Your Roof

If you do think you have a leak in your roof, but you are not sure where, here are some ways you can help pinpoint the general location:

  • Missing or broken shingles easily allow water to penetrate the now-vulnerable and bare roof decking
  • Water stains on ceiling will help you pinpoint the leak location
  • Look around your chimney, gutters, and other parts of your roof where there could be gaps that water can slip through
  • Mold or algae growing on top of or under your shingles
  • If there is sunlight shining through your attic, find the hole where light is coming in
  • Clogged gutters leave ponding water that can seep through your roof
  • Ice dam build up after a heavy snowstorm leads to melting snow and leaking roofs
  • Roof valleys are the places where two slopes meet, so water can easily pool in between the ditches

General maintenance and routine roof inspections using an infrared scanner will help prevent expensive and frustrating leaking roof problems.

How Do You Detect a Wall Leak In Your Home?


water leak detection

Water In Your Walls Can Cause Major Structural Damage.

Water leaks happen in homes all of the time. The biggest problem is that they tend to go unnoticed until they have caused significant damage. The reason for this is because, water that begins to leak behind walls usually gets absorbed into the wall and will not become apparent until the wall or paint begin to blister or even bubble up. To detect a wall leak, you really just need to pay extra attention. A way to do this is to make sure you are always checking your water bill at the end of the month to see if there is a large rise in water usage. Another way to do this is to also check your water meter. You can turn off all of your water for several hours and write down the number the meter is at, then go back and check it after a few hours and see if the meter has risen while you were not using any water. If you think you are having a water leak in your wall but do not know the source, you will want to call a professional at Dimensional Drones and have them do water leak detection using an RWS device. Just give us a call at (512) 402-8877 if you need a professional to come out and check for leaks in Austin, TX.

Why Is Your Commercial Flat Roof Leaking?

Flat roofs are an exceptional commercial roofing choice for a number of reasons. They are sturdy and they offer years of protection. However, like many roof materials, flat roofs are susceptible to damages. One of the biggest causes of damage is from roof leaks. But why is your commercial flat roof leaking? To learn more, keep ready to find out why your commercial flat roof might be leaking.

Water Ponding

Why Is Your Commercial Flat Roof Leaking?

Why Is Your Commercial Flat Roof Leaking? Find Out Here!

When a flat roof doesn’t have an adequate draining system, it can lead to water ponding, which is the incapacity to shed or drain water off the roof. Because of this, it can cause commercial flat roof leaking issues.

Roof Damage

While a flat roof is very sturdy, it can still become damaged. Roof damages can happen because of constant UV ray exposure, the changes in temperature or even severe weather can cause cracks and blisters on the roofing material. These can cause water to seep beneath the roof material and into your building.

Inadequate Flashing

Although the roof is completely flat there are other things like vents and pipes that can be present on the roof. When these components don’t have the proper flashing around them, water can seep into the areas where the vents and pipes are.

Old Age

A flat roof that is past it’s prime can have plenty of damages. Common damages are cracks, poor flashing, and moisture, all of which can cause water to find itself in your building.

We are committed to making sure you understand everything that is happening inside your walls so that you can get them repaired as quickly as possible.

Why Choose an Infrared Wall Inspection

An infrared wall inspection can help you better understand what’s happening behind the drywall. Here are some other reasons why infrared is the best choice for your building inspection.

It’s Non-Invasive

It Creates a Target for Repairs
With traditional inspections, it isn’t always easy to determine the source of the problem. This means you could spend a lot of time and effort looking for the problem before you spend the money to repair it. An infrared wall inspection allows you to pinpoint exactly where the problem is, so you know which part of the building needs to be repaired.

It Can Prevent Serious Problems
Unlike traditional inspection methods, infrared inspections can pinpoint problems before they damage the walls. This allows you to repair the problem while it is still small and relatively affordable.

If you have questions, or would like to schedule an infrared wall inspection in Austin, TX, cal (512) 402-8877. We can help you with all your commercial building inspections.

Why Use Drones For Roof Inspections

The future of technology is right in front of our eyes and is making our everyday lives easier and easier through each passing day. Drones are becoming the new wave of roofing. They allow us to see things that we cannot and help to detect damage in places that would be dangerous for a roofer to try and access. A roofing company that uses drones to do parts of their roofing inspections are able to see more and find more damage than a traditional inspector could.

3 Reasons To Use Drones


Safety Inspectors and roofers get hurt on roofs every single day. By using a drone, it would significantly lower the risk of getting hurt because you wouldn’t have to go up a ladder anymore. This will also allow the inspector to access places that they may not have been able to before and using special technology that drones have, it can see the damage and locate exactly where it is.

Faster – Without the burden of having the climb up a ladder and walk around on a roof, it will significantly cut down the amount of time it takes to do an inspection or locate the damage. Because a drone has the ability to fly, it can essentially cut the entire inspection time in half.

Cheaper – By having a drone service it will provide a cheaper route to roof inspections because the inspector will not need to lug around all of the heavy equipment, which will also result in a faster inspection. Less time on each customer means a cheaper fee.

Drones are a great way to use technology to your advantage. There are too many pros to name here, but if you have questions or even concerns, give Dimensional Drones a call at (512) 402-8877, today.

Benefits of an Infrared Roof Inspection

Roof Inspection

When You Pair IR Technology with a Drone, You Have a Powerful Tool for Commercial Roof Inspection.

If you own a commercial structure, an infrared roof inspection can provide many different benefits. Aside from IR’s capability to reveal hidden issues, you can avoid a few key pitfalls associated with regular inspections. If the time has come for another inspection of your commercial roof, you’ll definitely want to consider the benefits of IR technology.

Less Invasive

Traditional roof inspections are inherently invasive. The presence of someone on your roof, regardless of how careful the person attempts to be, will naturally cause some amount of wear and damage. When it comes to the location of leaks and moisture-related problems, the inspector may have to damage your roof further. An infrared scan negates the need for core samples or other practices. Additionally, with infrared scans performed from above by drones, you negate the need for a physical presence on your roof.

More Comprehensive

An infrared roof inspection can reveal hidden issues that will elude the most expert traditional inspector. Water represents the primary threat for most roofs. Since water absorbs and disperses the sun’s heat at a different rate from roofing materials, water within your roof will stand out in a thermal image. This provides for a much more comprehensive review of a roof, its issues, and any hidden dangers.

Fast and Easy

A drone-enabled infrared scan can cover much more territory than a physical inspector. When it comes to large commercial structures, or facilities that contain many buildings, this makes a big difference. You can also generally save money as compared to the cost of a traditional inspector.

At Dimensional Drones, we specialize in infrared roof inspection in Dallas, Houston, Austin, San Antonio, TX, and around the state. To learn more about the unique benefits this service provides, give us a call at (512) 402-8877.
