Would You Trust a Drone Service for Your Roof Inspection?

drone inspection

You really shouldn’t invest in a new building or home until you’ve had a roof inspection, even if you think you’ve found the one. You don’t want to buy a building or home with weak or damaged roofing, then find yourself with hefty bills to repair leaks and structural damage.

One of the latest technologies inspectors are often using to evaluate a roof involves using a drone.

But roofing contractors perform this importantl task differently, preferring a close-up, hands-on examination. Can you trust a drone inspection? Or should you hire a roofing contractor instead?

How Roof Inspections Work with a Drone

Many home inspectors today don’t actually get up on the roof to check its condition. And many of those who do climb up may stay on the ladder and look at the roof from there. The high cost of liability insurance is the most common reason cited for this worrisome trend.

So to avoid injury to the inspector — and to prevent damage to the building — many roof inspections are performed with a drone.

How does that work? A drone pilot flies a helicopter-like machine, that’s outfitted with a camera. The drone can be adjusted to view different angles, and it can hover to zoom in on selected areas on the roof. As the drone flies, it takes photographs and videos to allow the inspector to evaluate the roof’s condition.

How Roof Inspections Work with a Professional Roofing Contractor

A professional contractor doesn’t rely on drone photos or videos to determine the structural integrity of your roof.

Roofing contractors actually climb up on the roof to look at the roofing materials, underlayment and, if applicable, the roof decking itself.

During a professional roof inspection, the contractor also evaluates the condition of the flashing around the chimneys and vents as well as the soundness of the rain gutters, drains and downspouts. He also examines the deck and structural supports from the attic side.

Professional Roof Inspection vs. a Drone Inspection

A drone inspection gives results that are easy for inspectors to review. And pictures or videos often speak louder than words. With a drone inspection, buyers and sellers can see any roof damage for themselves.

That said, relying on a drone service may not be the best plan. Overhead photos cannot adequately assess any underlayment or deck issues, nor can drones check from inside for water damage or structural support problems.

A roofing contractor will perform a much more in-depth analysis of the roof, manually testing the strength and flexibility of the shingles or tiles as well the other materials. Drone pictures can let you see the rooftop, but only a professional roof inspection will provide you a clear view of the structure’s condition.

How To Avoid a Roofing Scam


Don’t let a roofing scam hijack your finances and ruin your investment. Dishonest contractors are always out to take your money and leave your roof in shambles.

How can you identify a roofing scam when you see one?

Here are the key signs that an offer is either too good to be true:

They Offer Repairs at No Cost

The #1 r roofing scam is when some workers show up at your door and offer you free repairs after a rain storm. They tell you that your insurance company will pay for the job and reimburse you later because the damage was from severe weather.

This is probably not true. A random roofer off the street can’t possibly know of the details of your insurance policy, so you shouldn’t trust their opinion. You should contact your insurance company directly.

They Ask to Inspect Your Roof

It’s a definite sign of a roofing scam when a “professional” asks to take a look at your roof. Do not allow any roofing contractor on your roof unless you have first verified their references and qualifications.

Some bad contractors may damage your roof on purpose to convince you to hire them for the repair.

They Ask for Your Insurance Information

Never agree when a contractor asks you to sign over your insurance benefits. They may claim that this will make the entire process easier for you since you won’t have to deal with the insurance company.

While this sounds like it would save you time, they could easily leave town after collecting the insurance claim, without finishing your roof repairs.

They Want You to Sign a Contract Today

No one should have to make a quick decision on whether to get a roof replacement. It’s one of the most expensive investments you will pay for as a property manager or homeowner, and you will only have to do it a few times in your life.

Some dishonest contractors use pressure, convincing property managers and homeowners to put down a sizeable deposit right away.

If you have never replaced a roof before, you won’t have any experience to determine if their business practices are solid, and scammers prey upon inexperienced property managers and homeowners. If you give in to the pressure, you may never see them again and your money will be gone.

Roofing scams can be avoided when you do research to find a professional roofer with a good reputation, such as ourselves.

Will A New Roofing System Add Value To Your Commercial Property?


With any commercial or industrial roofing investment it is crucial that property managers and business owners across Southern California are able to receive both a return of investment and long-term benefits on their spending. There are distinct advantages in replacing an old flat roofing system with a modern system. Newly installed flat roofing systems, if installed right will be more dependable and require less maintenance in the long run and whether you choose PVC or Modified Bitumen roof, you may benefit from higher energy savings and efficiency.

By working with us, an experienced commercial roofing contractor, we will be able to strategize and form a long-term relationship with you from the beginning of the new install to the end of the flat roof’s service life. This allows for a historic knowledge of the flat roofing system and easy maintenance. With this planning you can avoid the headaches and stresses when it comes to roof management and flat roof leaks.

As soon as the new commercial roof is installed, your building is worth substantially more than it was under the old, deteriorating roof. The building will be more secure, more weather-tight, and more attractive.

But exactly how much can you get in return from a new flat roofing system?

There is no question that a flat roof replacement is expensive. Seeing the total price for a professionally completed replacement can cause eyebrows to raise and hearts to skip beats. However, when property managers grasp a true understanding of where the money on a new flat roofing system is being spent, they will see saved dollars in the long-term and how a flat roof replacement is a true investment.

For those considering on selling a commercial property,  installing a brand new flat roofing system could be very profitable. If the sale of your commercial or industrial property is a step you are looking to take, you should take into consideration what prospective buyers expect from a flat roofing system and building efficiency. Low maintenance costs, durability and a long life cycle flat roof is ideal.

By replacing a flat roof with a durable and reliable flat roofing membrane, you not only reduce future spending on flat roof repairs, but you also eliminate costs associated with the damage a leaking roof can cause. With green roof bylaws that require energy saving credentials, you could end up saving thousands of dollars more than the costs required to achieve it.


How To Get Your Roof Ready For Solar Panel Installation


When you’re planning solar panel installation at your home or business, you must make sure that your roof can support your sustainable energy goals.
Take these three simple steps before installation of your new photovoltaic array, and you can rest assured that your roof will be ready to support your solar panel installation.

Step One: Contact a Licensed Roofing Contractor and Schedule a Free Roof Inspection

Do you know if roof can support the weight of a photovoltaic array? Solar panels are pretty heavy — each weighs about 40 pounds, not including the mounting racks and hardware. To provide enough power for your building, you may need dozens of solar panels. And your roof must have the right structural support in place to bear the weight of all that equipment. The best way to figure out if you have enough structural support is to schedule a roof inspection. A licensed roofing contractor can assess your roof’s condition.

Step Two: Get The Roof Repaired Before Installing Solar Panels

If during inspection the roofing contractor finds that your roof has some obvious damages, you need to address those problems now. It’s important that you have all repair work done before installing a photovoltaic array. Solar panels last at least 25 years, and most continue to provide power for much longer than that. Therefore, your roof must be in good condition if you want it to last for the life span of your photovoltaic array. Don’t be tempted to skip roof repair if the damage is slight. Small problems can easily grow into big and costly problems over time. And if you need repairs in the future, it will be expensive to remove your photovoltaic array to address the problem. You’ll have to have the solar panels reinstalled, which will cost you even more.

Step Three: Address Roof Obstacles before Solar Panel Installation

Shading can largely affect your photovoltaic array’s output. Roof penetrations like chimneys can result in unwanted shading, and they can also interfere with panel placement. To reap the most solar energy production, it’s important to address these issues now rather than later.

During your roof inspection, ask your contractor to see if any of the roof fittings or penetrations are likely to affect your solar panels. Some, like antennas and satellite dishes, can usually be moved to a better position if needed. Chimneys and vents can be more difficult to move, but may be possible.

Contact us to schedule an inspection to be sure your roof is ready for solar panel installation.

Types of Commercial Roofing Systems

Most low-slope commercial roofing systems have three principle components:

  • Weatherproofing layer or layers — the weatherproofing component is the most important element because it keeps water from entering a roof assembly.

  • Reinforcement — reinforcement adds strength, puncture resistance and dimensional stability to a membrane.

  • Surfacing — surfacing is the component that protects the weatherproofing and reinforcement from sunlight and weather. Some surfacings provide other benefits such as increased fire resistance, improved traffic and hail resistance, and increased solar reflectivity.

If you’re in the process of constructing a new building, or planning the replacement of an outdated roof on an existing building, there are five main types of commercial roofing systems to consider:

Thermoplastic Roofing

TPO roofing systems are among the fastest growing commercial roofing systems. Made of an especially durable material with a low-temperature flexibility and a high-temperature tolerance, these roofs are exceptionally resistant to ultraviolet, ozone and chemical exposure. TPO roofs can be expected to have a lifespan of 20+ years, and also feature a high resistance to fire, punctures, chemicals and high winds.

EPDM Roofing

EPDM roofing offers superior durability and versatility, making it one of the longest lasting types of commercial roofs available. EPDM commercial roofing systems are also typically easier to install, maintain and repair than most other types of commercial roofs.

BUR (Built-Up Roofing) System
A traditional built-up roofing (BUR) system derives its name from the building of a roof on-site using layers of base sheet, interply sheets and cap sheet or other surfacing such as gravel or liquid coating.

Hot asphalt (bitumen) is the bonding and waterproofing agent between layers. BUR is suitable for most low slope roofing applications. The higher the quality of the BUR materials and asphalt used and the greater the number of plies (and separate asphalt moppings), the more superior the roofing system.

APP and SBS modified bitumen
In the 1970s, technological advances in asphalt sciences led to the development of modifiers such as APP (atactic polypropylene)and SBS (styrene-butadiene-styrene) which, when added to unblown (unoxidized) asphalt, impart either plastic (APP) or rubber (SBS) characteristics. These additives provide enhanced performance characteristics to traditional asphalt. When coupled with reinforcements, such as polyester (superior elongation abilities) or fiber glass (high tensile strength), they create high-performance roof membranes.

APP modified bitumen membranes are self-adhering when heated using a roofing torch. SBS modified bitumen membranes can be formulated for torch application, but are more commonly applied using hot asphalt or cold SBS modified bitumen adhesive. The result is a BUR system with significantly enhanced performance capabilities. Continuing improvements in technology have also resulted in self-adhering SBS roof membranes.

When an SBS or APP cap sheet is combined with traditional BUR base sheets and interply sheets, the result is a hybrid roof offering the best of both systems – multiple plies and superior performance and longevity.

Photovoltaic Solar Panels

As energy costs continue to rise and America looks towards green and sustainable energy, many building owners are turning to solar energy roofing systems. PV solar panels installed over a rooftop or used with glass, membrane and roof-mounted tile, absorb sunlight and convert it to energy that can be used to power a building. Although not in wide use, PV panel roofs offer great potential to conserve energy and control skyrocketing costs.

Green Roofs

Perhaps of all the types of commercial roofs available today, green roofing systems have experienced the greatest surge in popularity in the last few years. Sedum green roofs are typically flat roofs that are partially or completely covered with vegetation and soil and planted over a waterproofing membrane. Green roofing systems reduce the urban heat island effect by soaking up heat and also are found to dramatically improve a roof’s insulation value – lengthening the lifespan of the roof by as much as two to three times longer and saving on heating and cooling costs.

All of these commercial roofing systems are excellent choices for industrial, institutional and residential low slope roofing. In choosing, factors such as site access, structural load, finished appearance, desired warranty and performance criteria should all be considered. Your ADCO project manager can help with more information.

Negative Impact of Ponding Water on Roofs

Without proper design, installation, and maintenance, a roof can suffer from ponding water, which can create a variety of adverse effects for the building.

According to the Asphalt Roofing Manufacturers Association (ARMA), ponding water is defined as the water that remains on a roof 48 hours or longer. The ARMA recommends that roof designs provide adequate slope (a minimum of one quarter-inch per foot) to guarantee the roof drains properly throughout the building’s life.

Typical issues that arise from ponding water on roofs include…

  • Accrual of dirt, debris and other impurities, which can mar the roof’s membrane.
  • Distortion of the roof deck’s construction, as ponding water can significantly swell the load. As water gathers, deck deflections can intensify, producing more ponding water that may adversely influence the structural integrity of the deck.
  • The emergence of algae and vegetation. If water is in place for extended intervals, algae and vegetation will probably result, triggering roof membrane damage. Furthermore, these materials can obstruct drains, often causing more ponding.

Ponding water often brings about hastened erosion and weakening of the membrane surface, leading to the roof system’s breakdown. Permitting even comparatively small quantities of moisture under the roof membrane may lower the insulation’s thermal efficiency. Plus, moisture invasion can cause severe impairment to the deck, insulation, membrane, and building interior.
