3 Different Types of Roofing Companies (Commercial, Residential, and System-Specific)
So, you’re having a roofing issue and you’re wondering who to contact.
But just because they have “roofing” in their name, does that mean they are qualified to repair MY roof?
Well, that depends on what “MY” roof is?
Is it residential? Is it commercial? Are you only interested in a certain type of roofing system?
Getting a quote from any roofing company is just like getting a brake repair quote from any place that deals with cars.
Car dealerships, local mechanics, and specialized brake shops can all repair your brakes.
But which one is best for your brake repair job?
The dealership is probably best if you have a warranty or have purchased the car there. The local mechanic deals with all types of repairs or cars that need more than one service. The specialized brake shop only does brake repairs. They probably have seen every issue with brakes, have spare parts, special tools for brake lines, etc.
Every car repair shop isn’t equal. Just like every roofing company isn’t equal.
If you need a roof for a residential house, we probably aren’t your best option.
But why is that so?
In this article, we want to clarify the three different types of roofing contractors, what they are good at, what they are bad at, with the goal to help you choose the right roofing contractor for your issue.
Let’s get started.
Commercial roofing contractors
Characteristics of a roof that’s the best fit for commercial roofing contractors: Usually 20,000+ square feet and within 150 miles of the roofing contractor. Commercial roofing contractors usually install flat or low-slope roofs. They also usually only install metal, single-ply, silicone roof coatings, or spray polyurethane foam roofing systems.
Commercial roofing contractors usually specialize in roofing larger buildings (usually more than 5,000 sq. ft.). The reason is that they have a large staff of roofers (most likely 50 or more) who can work in teams of 5-20 to get commercial roofing projects completed quickly.
The larger your roof is, the wider the range you have in choosing a commercial roofing contractor cost-effectively.
For example, if your commercial roof is 2,000 sq. ft., it would cost a contractor who is 200 miles away a lot more than a contractor whose right down the street.
If your roof is 200,000 sq. ft. Your range to find a roofing contractor widens because the overhead costs (such as gas, time to get to your roof) are a very low percentage of the total cost of the job.
The larger the project, the more options you have (cost-effective-wise) in choosing the best roofing contractor for the job.
Tips for choosing the best commercial roofing contractor:
- How long have they been in business?
- Do they have references you can call?
- Have they performed similar work that will be done on your roof?
- Do they have any certifications or awards?
If you have a residential house and you’re looking at getting a quote from a commercial roofing contractor, the price may be higher than you expected.
The reason is that commercial roofing contractors usually have:
- A large service team that’s on the payroll
- A full administrative team that’s on the payroll
- Large buildings used to house trucks, equipment, etc.
- Offer insurance, training, vacation, and full benefits to employees
A commercial roofing contractor is set up to perform large projects cost-effectively. Since they have a large amount of overhead, it doesn’t allow them to be the most cost-effective for residential roofs.
Residential roofing contractors
Residential roofing contractors are known for performing shingle work in local areas. Shingles are the roofing system that most residential roofing contractors use because of the aesthetics.
A metal roof wouldn’t look as appealing as a shingle roof, which can have many design options to best match the rest of the house.
Residential roofing contractors are great at getting to your house and performing the work quickly. This is mainly due to roofing contractors only sticking to local areas.
It wouldn’t make much sense to hire a residential roofing company from 200 miles away. The costs associated with traveling would make the job very inefficient.
Residential roofing projects tend to cost between $5,000 – $20,000 depending on a lot of factors, such as:
- How many square feet is the roof?
- How many layers of shingles are going to be applied?
- Does any deck work need to be repaired before anything is installed?
- How fast does the job need to be done?
- How high is the house in the air?
All of the factors include fluctuations in labor, time, or material, which add up to the cost of the project.
Characteristics of a roof that’s the best fit for residential roofing contractors: The roof is usually under 5,000 square feet and within 50 miles of the roofing contractor. Residential roofs can be low-slope or high-slope (very rarely will there be a flat roof). They usually install shingle roofs.
System-specific roofing contractors
A roofing contractor can be commercial or residential, but the type of roofing systems they specialize in can differentiate themselves.
This is beneficial for a property owner who’s already done research on what type of roof they want. Now it’s time to find a contractor that specializes in that roofing system.
Here are the most common types of roofing systems and a quick summary of each.
Spray Polyurethane Foam
Spray polyurethane foam, or spray foam, is a roofing system that’s installed as a liquid, which expands into a foam, creating a closed-cell, monolithic layer over top of an existing roofing system.
The best part about a spray foam roof is that the initial installation requires the least amount of tear-off of the existing roof as possible.
Also, a spray foam roof is renewable, which means after it’s warranty (10-20 years) all that needs to be done is to clean the roof and add more coating overtop. This gives the roof another 10-20-year warranty, doesn’t require any tear off, and is performed for ½ to 1/3 of the cost of any other roofing system.
Single-ply roofing systems are sheets of rubber or synthetics that can be ballasted (use rocks to hold the roof down), mechanically-fastened (use screws and plates to hold the roof down), or chemically-adhered (using adhesive to hold the roof down).
The best part about a single-ply roof is that it’s easy for a roofing contractor to install, which means it can be less expensive than other roofing types.
Metal roofing is the use of large metal panels that are installed over the insulation on a roof. Most metal roofing systems use corrugated galvanized steel, although other materials such as aluminum or tin can also be used.
The best part about a metal roofing system is that it can typically last about 50 years without having to replace the metal panels.
Shingles are mainly for residential housing because of aesthetics, but they are also common on other structures such as churches and barns.
Shingles can be made from wood, slate, metal, plastic, ceramic, and composite material such as asphalt.
The best part about shingles roofs is that there are plenty of contractors who can install them, and there are many options when it comes to colors and design.
Silicone Roof Coatings
Silicone roof coatings are a newer roofing solution that commercial buildings are installing. In the simplest terms, it’s installed by:
- Removing all the saturated areas off of the current roof
- Replacing the saturated areas with new, dry materials
- Cleaning the existing roof
- Adding coating overtop of the entire roof
There are other steps such as adhesions tests to make sure the coating will perform like it should, seam treatments if the roof has seams and a few other quick steps. You can watch an entire silicone roof coating installation in this video:
The best part about silicone roof coatings is that they usually save the building owner money on their energy costs because the coating reflects the sun.
Another benefit is that silicone roof coatings are considered a repair and not another roofing system.
This is critical for roofs that already have two or more roofing systems installed.
Due to building codes stating that the maximum amount of roofing systems a commercial roof can have is 2, an entire roofing system may need to be removed to install any other roofing system besides silicone coating.
