Checking if Your Flat Roof has a Low Spot

low spots on flat roofing

Low spots in flat roofing are common and can cause damage and expensive repairs if not taken care of. But how do you know if you have any low spots? There are signs to look for to identify a low spot, so you can contact a roofer to help get it taken care of before it causes too much damage.

Checking if Your Flat Roof has a Low Spot

Pooled water: Flat roofing is not completely flat and has a small incline. This allows water drain off to the gutters away from the roof. Water that has pooled or accumulated is one of the first signs that you have a low spot, as it prevents water from its natural flow down the gradient. These pools will weaken the roof and eventually cause leaks and even structural damage to the roofing system.

Clogged drains: When drains or gutters are clogged, they collect water. The strain of the backed-up water weight can cause a low spot. You need to check your drains regularly and clean them out if you notice clogs. You should then check to see if water runs off, if not, then you may have a low spot.

Collected dust: Low spots provide protection from the wind for leaves and debris so piles on the roof could indicate a low spot. Collected dirt and debris can also become heavy like water causing damage to roofing materials. You need to clear these out and get the low spots repaired right away.

Concentric sediment circles: Unless you are on the roof directly after it rains, then you may not see any puddles. They do leave tracks though. Puddles will leave concentric circles after the water has evaporated that indicate there was once a pool there. These circular deposits let you know that you have low spots.

Moldy smells: Pooled water can collect bacteria which can increase chances of mold growth and odd smells. Black mold growing on your ceiling or strange musty smells can indicate that water is collected on the roof in a low spot.

Changes in the ceiling: If your ceiling is sagging, stained, or dragging, then you have a low spot in the roof. Low spots collect water which becomes heavy and causes leaks into the building. The signs will be apparent on your ceiling before you even identify the spots on the roof.

If you know what to look for and you check regularly, low spots are easy to identify. Once identified contact us right away to help get them fixed. We use a number of different methods to fix low spots so we guarantee to find a way to get your roofing repaired right away.

Checklist for Hiring 3rd Party Contractors

Roofing flat roof

As a building owner, your building is an investment that you work hard to protect. This means that when it comes to maintenance, you don’t want to just hire anybody. The roof is an important aspect of any building and poor quality roofing can cost you. You need to ensure that any roofing work done is of top quality and that the contractors providing the work are reliable and experienced. This checklist below can help you identify the best roofing contractors so you can hire one that you trust.

Checklist for Hiring 3rd Party Contractors

  • Go slow: Take time when searching and researching contractors and do not hire the one offering the best price or biggest promises. By taking your time to research roofers, ask for recommendations, and confirming they have the experience, you are likely to get a high-quality contractor. You want to hire slowly, but when it comes to firing, you need to move fast. You want to remove an unqualified person performing poor quality work before any real damage is done.
  • Conduct interviews: Part of taking the hiring process slow involves interviews. Despite the reputation, you still need to meet with a contractor face-to-face so you can with them first to form your own opinion and ask about your own specific project needs.
  • Avoid bidding mistakes: Large roofing projects will be costly so you have to make sure that your money is well-spent. Go through all bids carefully and check that all your specifications are met before deciding on a roofer.
  • Protect from any loss: Always get verification of licensing and a certificate of insurance before officially hiring a contractor. You also want to confirm that they carry worker’s compensation insurance. Full coverage protects all parties involved in the event any damage or injury occurs during the course of the project.
  • Get everything in writing: All job specifications, timelines, and pricing need to be fully documented in writing before you sign a contract. It is also advised to have all contacts looked over by legal counsel before signing.


Regardless of the size of your roofing project, be it small repairs or a full replacement, you want a trusted and experienced roofer doing the work. Be prepared and plan what you need and what you expect so you know exactly what you are looking for. Using this list can help you narrow down your search and find you a roofer you can trust.

Spray Foam Roofing Maintenance


Summertime is a great time for roofing installation and maintenance. Both homeowners and commercial facility owners take advantage of the better weather to get their roofs repaired, restored or replaced. When it comes to fixing spray polyurethane foam roofs, or full replacement of existing roofs with a spray foam system, there are some important guidelines to remember.

Spray Foam Roofing Maintenance

Spray Polyurethane Foam on the Roof

Spray polyurethane foam (SPF) roofing is a high density, rigid and closed-cell spray foam which is applied over new and retrofit roofing substrates. SPF acts as a protective roofing layer, a thermal insulator, air barrier, vapor retarder, and a waterproofing solution. These systems are cost-efficient and can be applied to any shape and substrate in roofing. When applied professionally, spray foam roofing locks every portion of the roof into place and creates a monolithic membrane which eliminates the need for mechanical fasteners. The material is durable and lightweight while delivering a compressive strength of 40 to 60 pounds per inch.  As one of the most affordable roofing options, spray foam protects the structure from water intrusion, hail and wind uplift. It also acts as a high-performance insulator, preventing heat transfer through the roof deck, which minimizes the escape of conditioned air, resulting in reduced energy bills for the life of the roof.

Ideal Applications

Spray polyurethane foam systems are ideal for a wide range of commercial, agricultural, industrial and residential applications. It is especially useful when the roof is an unusual configuration or shape or when a sloped application is required for controlled drainage.
Because of its material characteristics and ability to adhere and seal during the application, spray foam works well in situations when the substrate includes numerous penetrations. The foam’s resiliency also makes it ideal for regions where significant rain or wind occurs.

Protective Coatings

Spray foam roofing must be coated once the installation of the SPF is complete. The elastomeric reflective roof coating serves as a protective barrier over the SPF to help maintain the integrity and improve the performance of the roof by protecting it from UV radiation and the elements.

Replacement vs. Restoration

Existing roofs in total disrepair require either total replacement or restoration. Two common factors, weight and cost, determine the choice made. Full replacement is cost-prohibitive which makes restoration a more appealing option. Because spray foam may be directly applied over an existing roof there is no need for removal, making it a cost-effective solution to the problem. It is lightweight and is thus ideal for structures unable to bear excessive loads.

Maintenance of Your SPF Roof

The roofing industry standards recommend that SPF systems undergo roof inspection two or more times per year. Gutters, scuppers, and drains should be reviewed during inspections to ensure dirt and debris are not restricting drainage and that there are no cracks in the coating.

Final thoughts

Rooftop units and penetrations also need to be checked to ensure flashings are all properly sealed to protect against weather. Condensation from HVAC units should be piped to drains, skylights should be checked for a proper seal, heater stacks must have rain caps and seams in the units should be sealed with caulk. The surface area of the roof system must be regularly inspected for damage caused by objects, vandalism, foot traffic, and blistering. Finally, inspection best practices call for a review of any defects potentially present in the roof, such as erosion of the coatings of the spray foam, moisture penetration, cracks or pinholes. Spray foam is a self-flashing membrane that is cost-effective and easily maintained. Repairs are generally easy, so long as you watch for are collecting debris, drainage issues, foot traffic damage, and the degradation of the reflective roof coating. With regular inspections and preventative maintenance, your roof will give you long life and return on your investment.

Types of Drains for Flat Roofing

(A-One) Types of Drains for Flat Roofing

In reality, flat roofing is not entirely flat. There is always a slight slope towards the drain. Gravity allows the drainage system to work, so the water needs to have a natural flow away from the roof. Despite this, common drainage problems can occur associated with flat roofing.

Types of Drains for Flat Roofing

  • Foundation problems
  • Infiltration of water into living spaces
  • Water damage to walls and casings

These problems may be common, but there are still numerous advantages to having flat roofing and each type of drain system has its own pros and cons.

Inner drains

These sit away from the edge towards the center of the roof. A pipe system below the drain that shuttles the water away. Often these can form pools of water on the surface if there are any clogs to the system and the heavy water can eventually find a way into the building. These are also more expensive and repairs can be costly but they are great for colder climates as the pipes do not freeze.


These are small boxed drains that exit through the parapet wall. The slight slope of the roof allows water and debris to move along the roof and out the scupper. These too can become clogged and if water pools near the roof edge and if they are not connected to a downspout, then water can damage your foundation as it falls. These drains are not very expensive and are easier to maintain and prevent clogging.


These metal structures sit along the edge of the roof, collecting water as it flows down the slope. This help protects your foundation and helps to control the flow of water away from the roof. They are inexpensive and are the best way to protect your foundation, basement, and soils from erosion.

Final Thoughts

Flat roofing is a great choice for any building, just be sure you have the appropriate drainage system in place too. There are pros and cons for each choice so be sure to discuss all options with an experienced roofer. Call us today and we will help you decide which drainage system is best for your needs and your commercial flat roof.

Why Your Commercial Building Needs a Cool Roof?

(A-One) Why Your Commercial Building Needs a Cool Roof


You may live in a generally mild climate, but there will always be times where the weather can get unpredictable. There can be days where it gets so hot, you feel as though you could cook on the roof of your building. Planning ahead is the best way to prepare for such unexpected changes and to protect your roofing and building. The changes in weather from day to day can have big effects on your roofing surface, even if the heat only varies by a few degrees.

Why Your Commercial Building Needs a Cool Roof?

The majority of commercial buildings have dark-colored roofing surfaces and this is not good when the sun is out all day. These dangerous surface temperatures have allowed for cool roofing to be developed and it is becoming more popular for commercial roofing. Thanks to durability, reflectivity, and better energy efficiency, cool roofing systems are the best way to cut down your bills and increase the longevity of your roof. Cool roofing absorbs less heat than standard granulated roofing which means better inner temperature regulation. This reduces overall maintenance and energy costs and also ensures your roof will last longer by reducing the extent of any heat damage. Cool roofing also reduces carbon emissions and the overall “urban heat island” effect commonly found in large cities. This is especially important in today’s “greener” society. A fluid-applied cool roofing system is the best option. It can easily be applied over modified bitumen, metal, and single-ply roofing that is already in place. By avoiding re-roofing, you save a bundle as this can be a very costly process. Once you experience the more comfortable building temperatures and energy savings, you will realize the change was more than worth the initial investment.

Final thoughts

If you have a standard dark-colored roof and want to cut down on energy usage and carbon emissions as well as increase the longevity of your roof, do not wait. Call us today to discuss your cool roof options so we can help you keep your building temperature low and your energy bills even lower.

Let Us Help You to Waterproof Your Roof

A-One) Helping You to Waterproof Your Roof

The best way to protect your roof and building structure from water damage is with waterproofing systems. Waterproofing is a great way to keep the elements out and will also save on energy. A properly sealed building enhances the longevity of the building inside and out and saves on utilities because air will not have any place to leak or escape.

Let Us Help You to Waterproof Your Roof

What Causes Leaking?

There are a few conditions that will likely cause leaking in your roofing system.

  1. The presence of moisture or water
  2. Water moved along by a force such as wind or gravity
  3.  A breach in the envelop that allows water to penetrate

Waterproofing Methods

  • Liquid waterproofing membrane: This is a thin membrane consisting of a primer coat and a few topcoats that are very flexible and when cured, the liquid forms a rubbery coating that is difficult to penetrate.
  • Polyurethane liquid membrane: This is best for flat roofing areas and those exposed to severe weathering. Its higher flexibility makes it popular but expensive and it is also sensitive to moisture content.
  • Cementitious waterproofing: This is considered the easiest way to waterproof your building and the materials are easy to apply and find. Wetter areas with lots of rainfall are better suited for this waterproofing system.
  • Bituminous coating: This is a flexible and protective coating made with polymer-grade and reinforced fiber, and it is popular for coating surfaces like concrete foundations.
  • Bituminous membrane: This is popular for low-sloping roofing systems. As a self-adhesive, it is quite unlike any other membrane option. Composed of asphalt, filler, and polymers, its adhesive qualities can be improved by adding certain oils or resins for more enhanced waterproof protection


There are several things you need to do to ensure your roofing is waterproof and environmentally sound. Make sure you are aware of any water sources that the building and roofing could be exposed to and work with a professional to get a system designed to prevent leaks. Waterproofing is essential for the integrity of your roof, your building, and your investment. Call us today and we will help you waterproof your building to provide safety and peace of mind inside and out.

Checking Your Roof Drainage Before it Becomes an Issue

(A-One) Checking Your Roof Drainage Before it Becomes an IssueEven if you live where it doesn’t rain much, any rainfall can cause serious damage to your commercial roofing. Water weakens the roof and can cause pooling and leaks that lead to expensive damage and repairs. If any water reaches below the roofing surface, you could be looking at structural damage too. The best way to prevent this is with regular inspections and maintenance.

Checking Your Roof Drainage Before it Becomes an Issue

Water is one of the most destructive elements for roofing and any water into the roofing will be trouble. By inspecting the exterior of your commercial roof often you can identify if there is any damage or if there are any signs of water pooling. Regular exposure to heat and wear and tear weaken the roofing with time, and any water will only further damage it.

The main things to look for in your roofing should be bubbles in the roof or roofing membrane, damaged flashing, or cracks in the skylights. You also need to look for faulty gutters. These need to be cleaned and cleared of all debris. Anything that constructs water flow away from the roofing will allow for water to accumulate on the roof. Inspect the roofing exterior regularly as well as after any rain fall.

You also need to inspect the interior of the building too. Any damage found inside the building indicates that water damage has spread through the membrane and the structural integrity of the building is at risk . You need to check for:

  • Discoloration on walls and tiles
  • Deformations of wall surfaces
  • Leaking near skylight or window frames
  • Mold or mildew on interior surfaces
  • Rust along the underside of the roof surface

Regular inspection of both the interior and exterior of your commercial property will allow you to identify water damage before it gets too bad. Water damage can be repaired and prevented with inspections and when you work with a qualified and trusted commercial roofing contractor. Call us to day to discuss your inspection options and protect your roofing from the rain.

Estimating The Life-Cycle Costs Of Commercial Roofing Systems

life time cost of a roofing systemWhether you are a building manager or owner of a commercial building, it’s undeniable that getting the right value for money is something that is almost always on your mind, and you want to focus on all types of costs so you can make the right decisions. Most of the time, commercial projects are focused or evaluated based on their initial costs, but the truth is that there is more to consider. Every roofing system has different life-cycle factors to be considered, and such factors can have severe effects. You can choose a roofing system that requires less maintenance but is expensive to install or go for one that offers considerable energy-saving value, but costly to install, or even choose a system that is cheap to install but needs expensive maintenance. With so many options to consider, what are the areas of concern that you want to look at when estimating life-cycle costs?

Estimating Life-Cycle Costs Of Commercial Roof Systems


This is one of the most significant costs that you have to deal with when setting up a commercial roof. Even though some individuals consider it as one large sum, it’s not, and is made up of the following costs:

  • Cost of the roofing material to be installed
  • Cost of installation
  • Tear-off cost (might be required at times)
  • Operational disruption cost

All of the above expenses have to be considered when determining the life-cycle cost of roof installation.


When estimating the total life-cycle cost, repairs also have to be considered as they have different requirements such as tools needed, products used, laborers, and others. Repairing your roof, therefore has several connected costs that may include but are not limited to:

  • Clean-up costs
  • Interior damage costs
  • Costs of using temporary solutions before the repair is commenced
  • Mold and mildew elimination costs
  • Additional fees for emergency site visits and repair

(A-One) What To Look for In Your Roofing EstimateDurability

This is another major area that has to be considered when determining life-cycle costs. Even though most commercial roofs are designed to last long enough, you still have to carry out some maintenance services to ensure that the roof serves you for as long as it’s meant to. That means factoring in maintenance costs as part of the life-cycle costs. That is also in consideration that different types of roofing material will require different maintenance services, which may vary the life-cycle cost.

Energy savings

Since most modern roofing products offer energy saving capabilities, that might mean some “profits” from cost-savings coming into your pocket. In some cases, you might even qualify for incentives, rebates, or even tax breaks, depending on your location. Such benefits affect the life-cycle cost of a commercial roof system by lowering the cost a tad.


Evaluating the warranty that comes with your commercial roof system is vital to avoid any exclusions or caveats that can affect the life-cycle cost. Keep in mind that warranties are different and that not all will cover the roof’s lifespan.

Other potential costs

Even though the above-listed are the most common areas to consider when estimating the life-cycle costs of any commercial roofing systems, additional costs may come up as a result of:

  • Inflation
  • Replacements
  • Record keeping, and others

Final thoughts

Evaluating the life-cycle costs of your building’s commercial roofing system is imperative to making important decisions that may affect the future. Paying attention to such expenses can make your building exist smoothly as you anticipate all costs, or make your building become a hassle as time goes by.

How Roofers Can Use Drones?

(A-One) How Roofers Can Use Drones


New technologies are completely transforming the way things are in various industries all over the globe. Companies that keep up with the latest technology are staying more competitive when servicing their customers. Looks like no field of study will go without being affected; the roofing industry is not an exception. Typically, the tools that a contractor uses to survey and inspect residential and commercial roofing may vary greatly. So, it is important that you are doing your research to see what each contractor has in their disposal.

How Roofers Can Use Drones?

For those of you who are in the commercial roofing industry or expecting to hire a commercial roofer to do your next job, you may want to think about the innovations of using a drone to do your roof inspections. Particularly, since you may find that drones are speeding up roofing projects, while also saving the consumer money in the long run.

Old Traditional Roofing Inspections Performed on the Ground

First of all, when thinking about hiring a contractor to do a roof repair job, you will often find that the initial stages of this kind of project usually begins within performing a roof inspection. With the traditional processes that are presently used today, you will see the roofer climbing on to the roof to identify what is really going on. While many contractors are usually prepared to do these jobs using various safety techniques and procedures, there are some drawbacks and disadvantages to the traditional method. Some of the more common that is usually identified are as follows:

  • The roof is weak so the roofer can suffer potential injuries.
  • Additional roofing damage can be done in these inspections when the roof is already compromised.

New Roofing Inspections Performed by Drones

Today, the methods for inspecting a roofing system has changed dramatically. From climbing on the top of the roof to identify repair problems in using a drone to complete these inspections, the newer methods are bypassing the problems and issues that exist in the traditional inspection methods. So, how are these roofing contractors using the new techniques?

Use Precision Imaging to Complete the Inspections

When drones are used in these inspection jobs, they can be done with precision. According to some of the most recent advanced technology, this simply means that the contractor can use its functions to go farther than the top layer. Typically, when this is the case, the drone can be programmed to go farther down below the roof’s surface. For instance, if the contractor has access to drone fitted software applications, the inspection can uncover water damage that hides in places that are difficult to see. Typically, when the contractor uses thermal imaging to do their inspections, the roofer can use the technology to take measurements of peaks, ridges and other difficult to reach places. Once this information has been collected, the roofer will have the data that they need to identify what needs to be done to the roof without having to climb a ladder to make these distinctions. By using these images, the consumer can even expect the roofer to not only save them time but also money.

Work Digitally Encapsulated – Great for the Company’s Portfolio

In addition to completing the inspection of the roof with a precision image, these digital can use for a number of different purposes. For the smart and innovative roofing contractor, these photos can become a part of their company’s online portfolio.

On-the-Go Provisions Made

Roofing companies and homeowners alike can benefit greatly from this on-the-go technology. Specifically, after storms and other natural disasters where it would be difficult or impossible to get to the roof to see what is going on. Today, commercial roofing contractors have the ability to send these drones out to capture a picture of what is damaged and what needs to be done.
