What is a c-39 license?

Before we go into details about what the importance of using a roofer with a C-39 license is, it is important to understand what the C-39 license is in the first place.

C-39 is a specific license issued by the Contractors State License Board (CSLB) to qualified roofing contractors who have met specific requirements and satisfied stipulated licensing criteria. It is one out of 61 other licenses under CSLB’s category C of licenses which covers special contractor services including plumbing, fencing, fire installation and in this case, roofing.

The Scope Of The C-39 License

The C-39 license acts not only as a mode of identification for qualified roofers but also as a legal document stipulating the responsibilities and duties of a roofer as a specialty contractor. As a client, it would be important to understand some of these before getting into a contract agreement with your roofer. That way, you will have the law on your side in the event that the roofer does not hold up their end of the bargain. Below are the three key things covered under the license.

  • The roofing contractor’s duty and responsibilities

The license describes the roofer’s job as that of installing roofing materials or repairing those that have been damaged by different factors.

  • Expected results

According to C-39, the ideal result of a roofing contractor’s project would be a roof that is impervious to water, other liquids and solids.

  • Materials that they are allowed to use

Finally, the license mentions a few of the materials that a roofer might use including asphalt, pitch, tar, glass fabric and even weatherproof membrane materials.

In addition to these three, there are many other specific areas covered including payment arrangements and liability parameters in the even there is a breach in contract. In a nutshell, asking to see this license will save you as the client a lot of grief by keeping you informed and giving you a clearer idea of what to expect.

Importance Of Using A Roofer With The C-39 License

Having understood what to expect from a roofer based on the scope of the C-39 license, below are a few reasons why it is in your best interests to work with a roofer who is C-39 licensed.

  1. It helps ascertain the roofer’s qualification and skill level

CSBL licensing does not come easy and finding a roofer with a C-39 license means that you have one of the best in the state working for you. On account of all the qualification criteria that the roofer must satisfy, the license acts as the easiest way to determine whether or not you are working with a contractor who will offer you results worth the monetary investment made.

The licensing board that issues the C-39 licenses allows you as the client to access the roofer’s legal records in terms of contracts complaints made by the board and by other clients. This information comes in handy as it ensures that you are not blindsided by the roofer in any way.

  1. It is an objective indicator of experience

The C-39 license is only issued to roofing contractors with up to 4 years of work experience or those with one year experience and a college degree. With this in mind, it is very easy to estimate the roofer’s level of experience and in turn get an idea of whether or not to expect very high quality results.

  1. It is comes in handy when drafting a project contract

As a legally recognized document, the C-39 license comes in very handy when you are drafting a contract with the roofing contractor. This is because the license clearly stipulates the roofer’s abilities, rights and responsibilities. This information helps both parties come up with specific contracts where repercussions for breaching are clear and have a legal basis.

  1. It protects you from unlawful charging

It is common practice among unlicensed roofers to ask for payment in advance. This leaves you as the client vulnerable to scams or raw deals where the work is done in a substandard manner. Working with a C-39 licensed roofer on the other hand ensures that this is something that you will never have to worry about. This is because according to the license, the roofing contractor is not allowed to ask for more than 10%, or $1,000, whichever is higher, prior to beginning work.

  1. C-39 licensed roofers are always insured

Another importance of working with roofers with a C-39 license is the fact that they are always insured. This means that in the event that there is any damage to property or injury to the workers during the project, you will not be held accountable in any way.

After all is said and done, there is no denying the importance of the C-39 license whenever you are working with a roofing contractor. In addition to helping you settle for a qualified and certified roofer, it protects you in case of any issue including breach of contract by the contractor. Therefore, it is super important to ensure that you ask to see proof of C-39 licensing before signing any work contract or officially soliciting the services of a roofer. That way, you can rest assured that you will not only get great services but that you will get them in a legal and formally acceptable manner.
