California Laws on Hiring Unlicensed Contractors

Business engineer contractor who contracts to supplies consulting about working their job at construction site office headquarters.The state of California has very strict laws in place to prevent the use of an unlicensed contractor in any building works. There are stiff consequences for both the unlicensed contractor and the person who hired them. More detail about these laws and how to stay on the right side of them can be found below.

California Laws on Hiring Unlicensed Contractors

Underground Economy

The issue of unlicensed contractors is dealt with by the California State Licensing Board (CSLB). They consider unlicensed contractors to be part of the underground economy and this is something that they are very much against. It is not just the fact that the contractors are unlicensed that it is the problem, they may also be hiring people who are not qualified for the job they are carrying out. This is particularly important when it comes to building work as there is a danger that this work could be unsafe.

The Contractor Could Face Criminal Charges

The CSLB was set up at the request of the construction industry in 1929. It helps to protect customers by ensuring that there are strict regulations that contractors should adhere to. It also looks to raise the standards of construction in California. It has the power to investigate contractors that are suspected of not being registered. They are also able to carry out sweeps of construction sites to make sure that everyone who should have a license does have one. They will also make sure that all other regulations are being adhered to. Misdemeanor charges can be bought against anyone who is operating without a license. The maximum sentence for this charge is a $5000 fine or six months in prison. An administrative fine may also be given and will be added to the total. These fines can range from $200 to $15000. The penalty becomes more severe if the contractor continues to operate without a license. If they are bought before the court a second time then they will face a mandatory 90-day jail sentence. Their fine could also be increased to 20% of the total contract price if this is more than $5000. If another contractor’s license is used illegally then this will be classified as a felony charge. This will also apply to a contractor that has misled any potential client that they have the correct licensing in place. If this person is convicted of a felony charge then it is possible that they will serve any custodial sentence in state prison.

No Legal Rights In Cases Of Nonpayment

As well as the legal implications of not having a license, there are also financial concerns that can arise out of not being properly licensed. The CSLB has a number of free tools that contractors can use if they are dealing with a client that is reluctant to pay what they owe. Unlicensed contractors will not have access to any of these and therefore it can be quite difficult to get back any money that is owed. Unlicensed contractors also have no legal rights when it comes to suing for the money that they are owed.

Homeowners Can Be Considered At Fault

It is not only the contractor themselves that may face consequences for not having a license. If you suspect that your contractor does not have a license then you may be able to get some legal assistance. You will have to prove that to the best of your knowledge the contractor did have a license.

How To Report An Unlicensed Contractor?

If you suspect that a contractor does not have a license then you can report them to the CLSB. The state of California has very strict laws in place to prevent the use of an unlicensed contractor in any building works. There are stiff consequences for both the unlicensed contractor and the person who hired them.

Importance of Roofers’ Insurance

(A-One) Importance of Roofers' Insurance

When researching for the best roofing company for your domestic or commercial property, it is essential to ask about roofer’s insurance. It is important to deal with a company that has adequate insurance to protect against risks and disasters.

Importance of Roofers’ Insurance

  • Types of Insurance Options Available – The roofing job is dangerous, and there is a need for protection in the event of damage to your property or injury during the roofing repair job. Insurance against risks such as accidents and fires should be among your priorities.
  • General Liability Insurance – The general liability insurance will cover the contractor when there are claims against property damage, personal injury or bodily harm due to the roofer’s action. If an accident occurs and as result, there is a lawsuit, then the insurance will cover you and the roofing company for any claims payable. Therefore, as the property owner, you are not liable for any costs and are not responsible for anything that happens to your property that is not your fault.
  • Commercial Auto Insurance – This type of insurance is important for cars, vans, and trucks that are registered in your business name. You will be compensated should they suffer damage if they are in your property.
  • Workman’s Compensation Insurance – If an employee or a subcontract suffers an injury in the course of their duties under your projects, then they will be compensated against costs incurred and medical benefits. If your roofer or workers suffer injury, they can claim workmanship compensation as a substitute for their wages instead of filing a lawsuit against roofer or the property owner. While hiring a contractor to work on your roof, it is essential to set aside some money for both insurance policies.

The following Tips Will Help you in Choosing a Roofing Contractor

  • Do a simple background check –  The best roofing contractor is one who is experienced, licensed and insured. It is essential to do a background check before hiring a roofing contractor so that you can deal with roofer insurance who is credible and one of high integrity. Get references from previous customers. A reputable roofer will provide references from past satisfied customers. However, a roofing contractor of questionable character may not provide you with references and this may be an indicator they are not insured. Ensure they have general liability insurance and there is workmanship insurance before hiring them. By doing a background check of a contractor, you will be saving yourself the agony of doing business with businesses operating below expectation. An insured roofer will carry out the task with due diligence and will offer you the best price. Always contact the insurance company before signing up for the policy and verify their legitimacy.
  • Ensure your Roof Contractor is Licensed – Having someone work on your roof can be expensive. You might opt for a shortcut and hire a cheap contractor. However, it can even be costlier working with an unlicensed roofer. Chances are, a contractor who is not licensed is also not insured. Contractors with limited knowledge, expertise and training may not have the necessary skills, and you could be entrusting someone to do a poor job. It may lead to the cost of repairs. It can also lead to lawsuits, and you may find yourself on the wrong side of the law. You may end up paying fines as a result. The insurance company will demand licenses while signing up for roofer insurance. Therefore, you will not only be working with poor workmanship bit also be at risk of incurring more costs should your contractor, or the employees suffer an injury while on your property.
  • Get the Best QuotationA reputable roofer insurance company will provide the same quotes for their services. Their prices are reasonable and are similar to other reputable insurance companies. Research and compare quotes from other insurance companies.
  • Ask for Proof of Insurance – You need to request for insurance coverage of respective insurance company. This information should be made available to you upon request. If your contractor fails to provide the coverage, you may drop them and move to the next. Always consider roofers who are insured since if there are damages, you may be liable to cover the cost of the damages and any injuries that may occur during the job.

A long-term roofer is familiar with everything to do with the roofing system. The contract should have a deeper understanding of every component of the roofing system. It is essential to test their knowledge before hiring them, for the job. If the contract is well versed with the job, the chances are that they are insured and your property is not at risk.

Roofing systems must be able to withstand any weather and knowing the general weather of an area, means reliable roofing systems must be installed.

Rooftop vs. Side Yard Unit Air Conditioners: What You Need to Know

(A-One) Rooftop vs. Side Yard Unit Air Conditioners - What You Need to Know

Not all air conditioning units are the same. They may perform the same general functions but there are important differences when it comes to style and possible benefits. You typically get to choose between either rooftop units or side yard units. Depending on the benefits and comfort you are looking for, one system may be better suited to your needs than another. So long as you have the information about them, you can make the best decision for your building.

Rooftop vs. Side Yard Unit Air Conditioners: What You Need to Know

Rooftop Units

These are typically centralized cooling systems whereas side yard units are typically split systems. The rooftop units are secured to your roof and via a series of ducts and will keep the inside of the building cool. There are a number of benefits to getting a rooftop unit installed.

  • Air naturally cycles through the building easier because hot air rises as cool air descends. The natural movement of air makes these styles more energy efficient and they do not need to work as hard to circulate the air as the natural air movement will be doing most of the work.
  • Rooftop units are all-inclusive which means they have all components placed both inside and outside the building, so maintenance is much easier since everything is in one single location.
  • Rooftop units were originally thought to be bulky so newer designs and models have been developed and are much smaller and often invisible from the ground.

Side Yard Units

Despite the benefits that rooftop units offer, there are good reasons to get side yard units too. Ground units offer more diversity and customization as you can choose from a number of styles, powers, and sizes, to find exactly what fits. Many consumers find it a big advantage to be able to find a unit that matches their exact needs rather than compromising. With inside fans and an outside unit, you can easily replace one without having to replace the entire system which makes replacement costs much lower. Newer side yard units are quieter and are also not as bulky. Newer designs have been described as visually appealing which is giving them more attention than previous versions. These newer models are barely detectable which contributes to these A/C units developing a more positive reputation these days.

There are advantages to both rooftop and side yard air conditioning units and the choice you make will depend on your needs, budget, and the space you have available for installation. Both systems will keep you cool during those hot months.

Checking Your Roof for Hail Damage

hail proof roof

Hail storms can be just as dangerous as any rain or snow storm, resulting in breakage, damage, and serious dents to roofing. Some surfaces do not make it easy to identify storm damage which means some damage can go undetected and fixed. Over time this can cause serious damage to the internal and external structure of your roof. It is always recommended to work with a professional roofer to identify storm damage and get it fixed as soon as possible.

Checking Your Roof for Hail Damage

Maintaining the exterior of your roof will ensure that the inside of the building remains safe. To protect the internal structure of your property, regular maintenance is needed for your roof. This includes regular inspections after any and all storms or severe weather changes. Most insurance policies will cover damage caused by hail, but it needs to be properly identified by a professional first or your claim will be denied. Before you reach out to a specialist, there are a few things you can do to locate any damage caused by a hail storm. Check all the metal parts of the roof (flashing, valleys, and vents) for denting. Look at the top of the roof along the ridge cap as this flat area is likely to receive the most damage. You need to look for three types of damage when it comes to hail; bruising, cracking, and missing granules.

In addition to the top of the roof, there are other areas that will require inspection after a hail storm. Check your gutters and downspouts for dents. Gutters that have been significantly damaged need to be replaced so they do not cause blockages. The sidings and windows can also be damaged depending on the size of the hailstones so be sure to check those thoroughly. Any outdoor A/C or HVAC units may also be dented or dinged which can indicate that hail damage could have occurred elsewhere too.

Ignoring hail damage, as with any storm damage, will be a costly mistake. Finding and repairing dents or missing shingles is cheaper than having to replace your entire roof. The damage that is not fixed right away can get worse over time, allowing for leaks and internal structural damage. If you suspect any damage after a hail storm, contact us to provide a full inspection and we will help you identify the problems and get them fixed before irreparable damage is done.

our roof is one of the first lines of defense against bad weather, so it needs to be durable and reliable. Otherwise, you risk the integrity of the building as well as the property and the safety of the inhabitants inside. Mold growth, water damage, and cracked roofing need to be repaired immediately to avoid more expensive damage in the future. Check your roof after any hail storm and call us for an evaluation to get your roof back into shape before the next storm hits.

Top 5 Things Roofing Contractors Wish Their Customers Knew


It is important to work with a roofing contractor when it comes to caring for your roof, as this is the best way to ensure the roofing system is optimally maintained. The process of roof installation, as well as regular maintenance, involves technical jargon as well as lengthy paperwork and many consumers are easily confused and overwhelmed.

Top 5 Things Roofing Contractors Wish Their Customers Knew

Many contractors can find it challenging to work with clients that have little knowledge about roofing, so the more you know, the easier the process will be. Below are the top things contractors wish their clients knew before the job started.

#1 Price and value are not the same.

There will always be a contractor who will do a job for less but cheaper pricing is not indicative of better quality. Roofing systems are not like commodities so bargain hunting will not always get you the best results. Make sure you collect multiple bids and then base your decision on more than price. Consider the knowledge and experience of the contractor and be sure to check their references because when you make a choice based on price only, you may end up with inferior products and service.

#2 The importance of routine maintenance.

The more proactive you are about roof care, the longer your roof will last. Many roofers report that most roof replacements are done prematurely, and roofing can typically last longer wit better care. A little maintenance can go a long way and save you from expensive replacements and unnecessary repairs. Find a contractor that will work with you on to get the required maintenance done.

#3 Know when your roof is beyond repair.

There are a number of roofs that cannot be saved no matter what and putting more money into repairs will only be a waste. You will end up spending more in the long term than you would on a replacement. It can be frustrating when you make a lot of repairs and the roof continues to have problems. Work with an experienced contractor to assess and evaluate when your roof will need a replacement so that you can budget accordingly.

#4 Find a local roofing contractor who is established and reputable within the area.

You need a contractor that has proper licensing, valid insurance, and can perform all essential roofing installation and maintenance tasks. A roofer who only uses subcontractors may not have the appropriate or adequate insurance or licensing which could increase your risk for poor work. Be sure you always ask for the paperwork before hiring.

#5 Active membership to the National Roofing Contractors Association.

NRCA contractors know about industry code changes and technical issues. They are fully informed of the best practices to ensure you are a satisfied customer and they also provide the resources that all contractors need to make the best roofing decisions. This all means that you get the best possible service and roof for your building.

Biggest Mistakes Homeowners Can Make

A-One Construction Biggest Mistakes Homeowners Can Make

Your home is one of your largest assets, but so many homeowners are not cautious when selecting a roofing contractor to protect this important investment. Homeowners often wait until there is a significant roofing issue before considering roof system replacement. Painting and remodeling the inside of a home will do no good when the roof system has reached the end of its lifespan.

Biggest Mistakes Homeowners Can Make

This mismanagement of a home’s upkeep ends up being a costly mistake for many homeowners. For this reason, you should always work with an experienced roofer to regularly inspect and maintain your roof. When selecting a roofing contractor, you should look for a quality roofing contractor instead of choosing the one who is cheapest or one that can start the job first. There typically is a reason certain contractors are available immediately, such as the fact that no one else is buying from them.

Consider the research you do when purchasing a new car. You will likely not choose the cheapest model from a no-name auto manufacturer. The purchase is not impulsive and the dealership’s reputation is not poor when you finally make a decision. Because the roof protects your home it should be given the same consideration and priority as other major purchases. Consider these questions before hiring a contractor: How long has the roofing contractor been in business? Is his or her warranty longer than the number of years in business? Is the company licensed and insured? Have you checked with the Better Business Bureau? Knowing what you are purchasing and from whom is vital to the long-term enjoyment of your investment. Your roof system investment is far more effective when you remain proactive about its care. You should understand the importance of your roof and invest in maintaining it. Your roof requires service, just as an automobile requires regular tune-ups. Check your roof often to identify problems before they become worse and more expensive.

Have you removed the debris from your roof lately? Are the gutters and downspouts clear and allowing proper drainage for your roof system? Are the flashings around penetrations performing, or do they need attention? A roof system replacement should be done once, maybe twice, during the lifetime of a roof. If you do your homework and give your roof a little extra attention, you will get the greatest value and protection both for your building and your investment.

Understanding Roofing Estimates and Roofing Proposals

Understanding Roofing Estimates and Roofing Proposals

When it comes to getting a roof installed or getting regular roofing maintenance it is important to know the difference between estimates and proposals. The two are frequently confused because there are similarities, but there are key differences you need to know when it comes to the work you need to be done.

Understanding Roofing Estimates and Roofing Proposals


Estimates include the types of materials that will be needed for a particular project. It also includes the scheduled time for the project, cleanup, and the contractor’s liabilities and any relevant warranty information for the roof and materials. Estimates also include how the roof is to be paid for and if there could be any possible add on costs. Any potential add-ons will be explained in the estimate in full. There are some contractors that will try to use the estimates as a means of getting you to agree to and sign a contract, by acting as if it is a formal proposal. This is not what estimates are supposed to be used for. Estimates help you evaluate which roofer you may want to work with based on pricing, materials, and warranty information. A professional and trustworthy contractor will give an estimate to provide the specific details and costs that will likely be involved in your roofing project s you can make an informed decision.


A roofing proposal sets the cost for a project that the contractor and building owner are bound to, like a contract. Most roofers will have set costs for materials and labor and will provide these costs in full, so you know exactly what to expect. They also give a detailed breakdown for each part of the project, including any additional costs. Proposals give a final price that cannot be exceeded regardless of what happens during the project. If the proposal numbers are not one that you like, then you do not enter into a contract with the roofer. Be sure to discuss every aspect of cost with the roofer upfront so you will be aware of exactly what you will be charged for. You will want to know exactly what you are signing and what you are agreeing to.

Not all proposals are the same and they differ by project, contractor, and consumer demand. Some proposals will also be lengthy while others are much shorter. Beware of proposals that are too short because they should contain details and critical information. Shorter proposals may be missing important and critical details. Your roofing is an investment, so collect your estimates to make an informed decision. Then, discuss a detailed proposal with your contractor before entering any contract so that everyone is on the same page.

TPO vs. Modified Bitumen: What to Choose?


The two most commonly used roofing systems in commercial properties are TPO and modified bitumen. Modified bitumen roofing has been around since the 1970s and TPO developed later in the 1990s but they both are ideal for all types of weather and have advantages and disadvantages.

TPO vs. Modified Bitumen: What to Choose?

Modified Bitumen Roofing

Modified bitumen systems are practical and lower in cost than other commercial roofing options. Bitumen was an upgrade from traditional systems and offered enhanced longevity and flexibility, but many contractors have stopped offering these systems due to a number of disadvantages that were recently discovered. Modified bitumen roofing was designed to improve the original version by adding substances like APP (atactic polypropylene). This made sure that the newer systems were resistant to UV light, oxidation, cracking, and blistering. Unfortunately, some manufacturers do not use enough APP to save money and this means the modified bitumen roofing doesn’t stand up to newer challenges as well as expected. The granulated surface of these systems was also added to provide additional UV resistance, but makes it more difficult to identify cracks and leaks in the surface. These roofs also come with a serious fire hazard if there are any open flames nearby during installation.

TPO Roofing

Thermoplastic Polyolefin (TPO) roofing is the more modern choice in large-scale roofing and is installed typically in one of three ways; ballasted, mechanically fastened, and fully adhered. It has become popular because of the numerous benefits for building owners.
The single-ply membrane is tear resistant, UV resistant, and resistant to chemical and grease spills. They are also fully recyclable which is popular with today’s more eco-friendly society. There are also no plasticizers in the insulation which adds to it’s “green” image and appeal. You can also pick from an assortment of colors to match your building or opt for the traditional and energy-saving white. If the current roof is in good condition, you can apply TPO over existing metal or bitumen roofing. You save money and time because you don’t have to tear off and dispose of the old roofing. TPO is also reheatable and has a smooth and easy-to-clean surface as compared to the granules of bitumen roofing. TPO membranes are much thicker material which protects your roof from falling debris and tears.
You must always ensure that your roofing system is installed correctly as most of the problems detected with TPO systems have to do with poor installation. With quality and an experienced roofer that installs the system and welds the seams correctly, you can be assured that your TPO roofing will be more effective and will last longer than expected.

Whichever roofing material you decide to go with, we have the expertise and resources to get your new commercial roofing installed with quality and efficiency. TPO is the preferred option but we understand that sometimes traditional materials are great too. We are here to answer any of your concerns regarding your next roofing project and find the best fit for your roof.

13 Reasons Why Rooftops Are The Best

(A-One) 13 Reasons Why Rooftops Are The Best


1.Those views. Standing on a rooftop means you can see for actual miles.

2. Height gains. Especially important for short people who don’t know what it’s like to see over the heads of others…


3. Loads of cool space-saving stuff happens on rooftops in big, built up cities because there’s nowhere left on ground level. We’re talking vegetable gardens, beekeeping, and most importantly, bars.

4. You can probably see your house or workplace and it’ll make you feel like you’re in some super mega realistic Google Map.

5. Sunsets and sunrises will never look better than from the top of a roof.


6. If you have to climb a load of stairs to get up there, there’ll be some kind of view-based reward and you can tell yourself that you don’t have to go to the gym for another week.

7. The greatest movie scenes were filmed on the top of roofs; just look at Mary Poppins’ chimney sweep dance, King Kong’s accidental hostage situation and The Hangover’s pre-s@#$-hitting-the-fan Jager shots.


8. Extra special rooftops have extra special things on them, like tennis courts and movie theaters.


9. They’re the perfect spot for first dates because if you run out of chat, you can just spout on about the views until they tell you to shut up/kiss you to make you stop/run away.

10. It’s like being given a telescope over the city. You’ll spot buildings you want to visit, green spaces you want to roll around in and other rooftops you want to love life from.

11. The higher you are, the more cool points you’ll earn. “We had to climb one flight of stairs” wows no-one, but five is impressive.

12. The Beatles played their last ever gig on the rooftop of Apple headquarters in London in 1969.


13. Some rooftops have yoga classes on them which is the most zen thing ever.
