How to start a commercial roofing division when you already run a residential company

Many guides on how to start a roofing business assume you are starting from nothing: form the company, get licensed, buy a truck, find a first customer. If you already run a residential roofing company, you have done all of that. The harder question is how to start a commercial division without hurting the business that already pays the bills.

The earlier post on why commercial roofing is a different business than residential covers why the two are not the same game. This piece is the practical follow-up: a launch sequence for an existing company adding commercial work, in an order that tends to protect the residential side while the new division finds its feet.

Step 1: Check readiness before you check the market

Before you look for commercial work, look at the company you have. A few honest questions:

• Is the residential side steady and profitable enough to carry a slower cash cycle?
• Does someone other than you run residential day to day?
• Can you free up one strong person to focus on commercial without leaving a hole?
• Are you prepared for longer sales cycles and more people involved in each yes?

If the residential business only works when the owner is in every decision, adding commercial will usually make both sides worse. In that case, the first project is the owner bottleneck, not the new division.

Step 2: Write the plan before the first bid

A commercial division started by accident tends to stay accidental. Before you chase anything, write down the work you want, the work you will pass on, who owns each part of the job and how the money comes back. It does not need to be long. The one-page roofing business plan for a commercial division walks through it section by section.

Step 3: Sort out insurance, bonding and licensing questions early

Commercial customers and general contractors often ask for certificates of insurance, specific coverage and sometimes bonds before they will look at your bid. Licensing rules vary by state and sometimes by city, and some places treat commercial work differently from residential.

Sit down with your insurance broker, a surety contact and, where needed, a lawyer. Ask what your current coverage and licenses allow, and what would need to change for the kind of commercial work in your plan. Do this before you chase work. A first commercial opportunity can stall at the certificate of insurance long before anyone reads your estimate.

Step 4: Name the first commercial seat

Commercial needs an owner inside the company. It is tempting to hand it to your best residential foreman or salesperson on top of their current job. That often means commercial gets whatever time is left after residential fires.

In many companies the first commercial seat is one person who sells and helps run the early jobs, with the owner backing them up rather than doing the work for them. Write down what that seat owns and how it reports. The post on naming seats without a bloated org chart shows how to keep this simple.

Step 5: Learn the systems and the paperwork

Low-slope roof systems such as TPO, PVC, EPDM and modified bitumen install differently from steep-slope residential roofs. Manufacturer reps and industry associations offer training, and it is worth using before your crews are on a commercial roof.

The paperwork deserves the same attention. Commercial jobs often come with written specs, submittals, manufacturer warranty requirements and closeout documents. On some bids a building owner's roof consultant writes the spec and watches the job. The post on working with the roofing consultant on a commercial bid covers that relationship.

Step 6: Start small and close to home

Many residential companies do better starting with commercial service, repair and maintenance work, and smaller re-roofs, before chasing large projects. Smaller jobs carry less risk while your team learns how commercial buildings and commercial buyers work. They also build relationships with the people who decide on the bigger jobs later.

Look first at who you already know. Some of your residential customers own or manage commercial property. Some local general contractors and property managers may already know your name. Qualify those opportunities against your plan rather than taking all of them. The post on how commercial opportunities actually open goes deeper.

Step 7: Build the first accounts on purpose

Commercial work tends to come through relationships: property managers, facility managers, building owners and general contractors who need a roofer they can rely on. Many of them have vendor approval steps before you can work for them. Ask what those steps are and complete them.

Once you are on a list, how you handle the small calls matters. Respond quickly, document the work clearly and close out cleanly. Commercial sales is its own seat, and building that sales seat for commercial work looks different from residential selling.

Step 8: Protect the residential business while you launch

Residential is usually what funds the launch, so keep it healthy. Keep separate reporting for the two sides so a strong residential month does not hide a struggling commercial start, or the reverse. Avoid pulling your best residential crew onto every commercial job. Look at both sides in a short weekly meeting, using an operating rhythm built for a commercial division.

Common launch mistakes

• Bidding a large project first to prove the division is real
• Sending the best residential crew with no commercial handoff
• Billing commercial work on residential timing
• Letting the owner become the whole commercial department
• Saying yes to every opportunity because the calendar has room

None of these are fatal on their own. Together they are how many commercial starts end with the owner deciding commercial is not worth it.
