If your commercial roofing is damaged, aging, or simply not performing as well as it used to then it is time to call in a roof repair specialist. A California roofing contractor can help you decide which type of roofing will best suit your needs and work within your budget. Before you pick up the phone there are a few things that you should know about commercial roofing and your property’s roofing in particular. This allows you to best communicate your needs and preferences to a roof repair specialist from our team.

Basics of Commercial Roofing

At first glance, roofing may appear to be very uniform, regardless of the building or its intended usage. However, there are two primary differences between commercial roofing and residential roofing that commercial building owners and property managers in Los Angeles should be aware of. 


The ideal materials for your commercial roofing are going to vary by the type of roofing, weather conditions in your area, and the budget you have to work with. Further, commercial roofing is typically a flat surface while residential roofing is generally steeper. Certain materials work better for a flat surface while others are preferable for an incline. A roof repair specialist from Journey Builders can help you determine which material is best for your commercial roofing Los Angeles or HOA roofing Los Angeles needs.

Residential roofing is often much more straightforward, simple, and easy to create and install. There are fewer obstacles to work around, such as chimneys, and the average surface area is significantly smaller in comparison to commercial property. Professional HOA roofing Los Angeles contractors can help you decide the best course of action to take that is attractive, cost-efficient, and within HOA compliance guidelines.

Commercial roofing Los Angeles services are best left to a highly qualified and professional California roofing contractor. This is because commercial buildings typically have more obstacles, such as external piping and rooftop HVAC units. Contractors need to be familiar with the obstacles they may encounter so they can work around them without causing any disruption or damage, either to the potential obstacles that they may encounter or to the roofing itself. 

Commercial Roof Inspection and Roof Repair

There are five fundamental details about your commercial roofing that you should be familiar with. Being aware of these features and their importance will help you make decisions that are informed and cost-effective. These factors are also applicable to residential property but may have different requirements and parameters depending on HOA roofing Los Angeles guidelines and the look you are trying to achieve.


There are two main types of roofing compositions- built-up roofing (BUR) and single-ply membrane. BUR is one of the oldest roofing types, able to withstand the test of time due to its flexibility, low cost, and ease of repair. It is made by alternating layers of tar and gravel. BUR is naturally UV resistant and can have a heat-resistant coating applied, but it has a lower lifespan than other types of roofing.

Single-ply roofing is newer and has more options for building owners to choose from. The three types of single-ply roofing primarily used in commercial buildings are:

  • Thermoplastic Polyolefin (TPO)- Considered the ‘gold standard’, TPO has both low-temperature flexibility and the ability to withstand high temperatures, which is ideal for California summers. TPO is also extremely durable due to its resistance to chemical exposure, ozone, UV rays, fire, high winds, and punctures. The average lifespan for TPO roofing is 20 years.
  • Polyvinyl Chloride (PVC)- PVC is made from a lower percentage of oil than TPO and EPDM. Like TPO it is resistant to chemicals, UV rays, and fire. It is also resistant to leaks and discoloration or damage due to sun exposure. PVC roofing is extremely strong; the minimum required breaking strength outlined by the American Society of Testing and Materials is 200 pounds per square inch but PVC boasts an incredible 350 pound per square inch breaking strength. 
  • Ethylene Propylene Diene Monomer (EPDM)- EPDM roofing has one of the longest lifespans when used on commercial property. It is easier to repair, maintain, and install when compared to other types of roofing used for industrial and commercial buildings. EPDM is available in sheets up to 50 feet wide, making the installation faster and significantly less labor-intensive.

There are four primary methods used in the installation of single-ply roofing. They are:

  • Mechanically Attached System- Used in flat roofing, it works by placing mounting plates from the insulation to the roof deck. The membrane is then secured in place and then attached to the layers of plates beneath.
  • Fully Adhered System- Used for roofs that are sloped, the roof insulation is anchored to the roofing deck with mounting plates, after which the roofing is bonded to the insulation. 
  • Induction-Welded Roof Installation- Used as an alternative when the mechanical attachment is not possible, this method is capable of decreasing the amount of penetrating fasteners used by up to 50%.
  • Ballasted System- Using large panels of roofing membrane made from rubber, this system takes the panels and loosely lays them onto the insulation. They are then covered by the ballast. Rubber roofing panels can be as large as 50 feet by 200 feet.

If there have been any alterations or additions made to your property then there is a possibility that your roofing is a combination of BUR and single-ply.

Aside from BUR and single-ply, metal roofing is also commonly used for commercial buildings. It is known for its incredible lifespan, averaging between 40 to 60 years, as well as its fire resistance and aesthetic appeal. Metal roofing can have an integrated snow removal system or integrated solar panels. Popular choices for commercial metal roofing materials are:

  • Coated or stainless steel
  • Copper
  • Aluminum
  • Tile sheets
  • Corrugated galvanized steel
  • Aluminum, zinc, and tin

Metal is very susceptible to corrosion and requires protective surface layers. This is especially important for commercial roofing in Los Angeles due to California’s hot summers, and LA having the country’s worst air quality for ozone pollution.


There are two ways in which roof ages, chronologically and chemically. Chronological aging is the amount of time that has passed since installation. Roofs that share a chronological age might not be in the same condition, even if they are made of the same materials and used the same installation method. This is due to chemical aging, which refers to damage caused by the elements such as sun exposure, high winds, high temperatures, low temperatures and ice, precipitation, corrosion, growth of mold and mildew, pollution, and air quality. 

Repair History

Be sure to maintain a thorough record of any repair work done to your roofing. These records should be comprehensive and include visual references to the extent, composition, and location of previous repairs such as diagrams, photographs, and drawings. 

Repair Budget

Have your budget ready at the beginning of the fiscal year so you can allocate it accordingly throughout the year, and never get caught off guard by unforeseen expenses such as roof inspection and repair work.

Manufacturer’s Warranty

Familiarize yourself with the coverage in your warranty plan before having any work done. Most commercial roofing comes with either full or prorated warranties for protection against manufacturing defects on the roofing material your California roofing contractor recommends.
