Building a Network of Roofing Subcontractors vs. Referring Work Out

There comes a point in every roofing contractor’s career where the phone rings more than your crew can handle. Maybe a hail storm blew through and suddenly you have 30 leads in a week. Maybe you landed a string of re-roofs in a subdivision and your two-man crew is booked out six weeks. Maybe you keep getting calls for flat commercial work that is not your thing.

You have two choices: sub the work out under your name, or refer it to another roofing company entirely. Both are legitimate. Both can make you money. But they are very different arrangements, and choosing the wrong one at the wrong time will cost you: either in reputation, in money, or in headaches you did not sign up for.

I have been running a residential roofing operation for over 15 years, and I have used both models at different stages. Early on, I referred everything I could not handle. As I grew, I started subbing out work under my company name. Both approaches taught me expensive lessons. Here is what I have learned about building a network of roofing subcontractors versus referring work to another company, and how to know which one fits the situation.

The Core Difference Between Subcontracting and Referring

Before getting into strategy, it is worth defining terms the way they actually work on the ground, not how a textbook describes them.

Subcontracting means you keep the customer relationship. The homeowner signed a contract with your company. You pull the permit under your license. You bring in another crew to do the labor, but your name is on the warranty, the invoice, and the yard sign. If something goes wrong, the homeowner calls you.

Referring means you pass the lead to another roofing company entirely. The homeowner becomes their customer. They write the contract, pull the permit, handle the warranty. You collect a referral fee for sending the lead, and your involvement ends there. If something goes wrong, it is their problem.

That distinction (who owns the customer relationship) changes everything about how you should think about quality control, pricing, risk, and compensation.

5 Factors That Determine Whether to Sub or Refer

This is not a coin flip. There are specific conditions that push you toward one arrangement or the other. Here is how I evaluate it every time.

1. Job size and complexity. Small repairs, single tear-offs, and straightforward shingle re-roofs are easy to sub out because the scope is clear and the quality standard is simple to verify. Large multi-layer tear-offs, steep-slope work, and anything involving structural repair get riskier to sub out because the margin for error is higher and your warranty is on the line. If the job complexity exceeds what you can confidently inspect and stand behind, refer it.
2. Your relationship with the customer. If a longtime customer calls you for a job you cannot get to, subbing it out under your name lets you keep that relationship intact. They trust you, not some other company. But if it is a cold lead from a Google search, referring it to another roofer costs you very little in terms of relationship equity.
3. Volume and timing. Storm season surge is the classic case. You might get 40 leads in two weeks after a hail event. There is no way you are subbing all of those. You would need a small army of crews you trust. In high-volume situations, referring the overflow makes more sense because you can process more leads with less overhead. During normal-volume periods when you get one or two jobs above your capacity, subbing is more manageable.
4. Geographic fit. If the job is 90 minutes from your usual territory, subbing it out is awkward. You cannot easily drive out to inspect the work, and your material delivery logistics get complicated. Jobs outside your service area are almost always better referred to a company that operates there.
5. License and insurance coverage. Some states require the permit-pulling contractor to carry specific insurance or bonding that covers subcontracted labor. If your policy does not cover sub crews, you are either paying for a rider or you are taking on uncovered risk. If the insurance math does not work, refer the job.

How Volume and Job Size Affect the Decision

I want to dig deeper into the volume question because it is the one most roofers get wrong. The instinct is to sub out everything so you keep a piece of every job. That works up to a point, and then it breaks.

The subcontracting ceiling

There is a natural limit to how many sub crews you can manage at once. For me, that limit is two. With two sub crews running alongside my own crew, I can visit each job site once during install, do a final walkthrough before the customer sees the finished product, and handle any punch list items quickly. I know the schedule, I know the material orders, and I can respond same-day if something comes up.

At three sub crews, things start slipping. I miss a site visit. A material order gets delayed because I was juggling too many deliveries. A customer calls with a concern and I do not even know which crew is on their roof. That is when mistakes happen, and on a job with your name on it, a mistake is a warranty claim, a bad review, or both.

When volume tips toward referring

Here is my rule of thumb. If I am getting more leads than my own crew plus two sub crews can handle in the next three weeks, I start referring the overflow instead of subbing it. The referral fee is smaller than the margin I would make subbing it out, but I am not risking my reputation on work I cannot supervise.

Storm season is where this really matters. After a major hail event, the phone does not stop. Every homeowner in the affected area wants an inspection, an estimate, and a start date. The roofers who try to sub out 20 jobs at once are the ones whose names show up in complaints. The roofers who refer the excess and focus on executing well come out of storm season with their reputation stronger.

Job size changes the math

On a small repair (a pipe boot replacement, a small section of flashing, anything under $1,500), it rarely makes sense to sub it out. The margin on small repairs does not cover the overhead of managing a sub crew. Either do it yourself or refer it.

Mid-range residential re-roofs in the $8,000 to $18,000 range are the sweet spot for subcontracting. The margin is large enough to pay your sub crew and still earn a meaningful profit, and the scope is manageable enough that one site visit can catch most quality issues.

Large or unusual jobs (steep-slope mansions, multi-family buildings, anything over $30,000) need careful judgment. The payout for subbing is attractive, but the risk is proportional. If you are going to sub a big job, make sure you have a crew you have worked with extensively and that your insurance covers the full scope.

Managing Quality Control on Subcontracted Work

This is where most roofing subcontractor arrangements succeed or fail. When your name is on the contract and the warranty, your quality standard is the only one that matters. The sub crew might do great work for their own customers but cut corners when they are working under someone else’s name. I have seen it happen more times than I would like.

What I check on every subbed job

I treat every sub crew job the same way I would treat a new hire’s first month. I inspect until I trust, and I never fully stop inspecting. Here is my checklist:

• Site visit during tear-off. This is when you see how they treat the property. Are they using tarps and protecting the landscaping? Are they pulling nails cleanly or leaving the deck chewed up? Tear-off is where sloppy crews reveal themselves.
• Starter course and drip edge inspection. I check this before they get too far into the field shingles. If the starter is misaligned or the drip edge is not properly overlapped, it is easier to fix now than after the whole slope is shingled.
• Final walkthrough before the customer sees it. I walk every roof before telling the homeowner it is done. I check the ridge cap, valleys, pipe boot seals, flashing details, and cleanup. If something is not right, the sub crew fixes it before the homeowner ever knows there was an issue.
• Debris and cleanup. Nothing kills your reputation faster than nails in the driveway or shingle scraps in the flower beds. I require a magnet sweep of the entire property and I verify it myself.

When quality slips on subbed work

Here is the hard truth: if a sub crew delivers bad work twice, they are off your list. The first time might be an off day. The second time is a pattern. It does not matter how affordable they are or how available they are. Your warranty and your reviews are worth more than the margin on any single job.

I had a sub crew that did solid work for six months, then got busy with their own jobs and started rushing mine. Missed caulking on flashing, sloppy ridge cap lines, incomplete cleanup. I gave them a direct conversation about it, they said they would fix it, and the next job was the same. That was the last job.

Quality Control on Referred Work Is Simpler, but Still Matters

When you refer a lead to another roofing company, you are not responsible for the quality of the work. But your name is still attached to the recommendation. If you send a homeowner to a company that does terrible work, that homeowner remembers who told them to call that company.

The quality standard for a referral partner is different from a sub crew. You are not inspecting their job sites. Instead, you are evaluating three things:

• Do they answer the phone and follow up promptly? The most common complaint I hear from homeowners about roofers is not bad workmanship. It is ghosting. If your referral partner does not call the homeowner back within 24 hours, you are going to hear about it.
• Is their online reputation solid? Check their Google reviews. Not to count stars, but to see how they respond to complaints. A company that handles a negative review professionally is one you can trust with your referrals.
• Have you seen their finished work? Before I refer anyone, I want to have seen at least two or three of their completed jobs in person. Drive by a recent install and look at the lines, the flashing, the cleanup. You do not need to get on the roof. You can tell a lot from the curb.

I keep my referral list short: two or three companies I trust. Having a long list dilutes the quality. You want to know your referral partners well enough that you would put your own family in their hands.

How to Structure Subcontractor Arrangements Fairly

The financial side of subcontracting is straightforward once you know the norms. But getting it wrong (even slightly) creates resentment that kills the relationship.

How sub crews typically get paid in residential roofing

The most common arrangement I have seen and used is paying the sub crew a per-square rate for labor. In my market, that rate runs $60 to $90 per square for a standard shingle tear-off and re-install, depending on the pitch, layers, and access difficulty. Steep-slope work commands a premium, usually 20% to 30% above the standard rate.

You handle the materials, the permit, and the dumpster. The sub crew handles the labor, their own tools, and their crew’s insurance. If you are supplying materials and managing the project, a typical margin for the general contractor (you) is 20% to 35% of the total job price after paying the sub crew and covering materials.

What to get clear before the first job

Every sub crew arrangement needs a few things settled from day one. It does not need to be complicated, but it does need to be clear:

• The per-square labor rate, including any premium for steep or complex work
• Who supplies materials, dumpsters, and equipment
• Who handles the permit and inspections
• Payment terms: when the sub crew gets paid after the job is complete
• Cleanup expectations and who handles the final magnet sweep
• What happens if the homeowner has a warranty claim on workmanship

I put all of this in a simple written agreement. Not a stack of papers: a single page that both parties sign. It protects both sides and prevents the “I thought you were handling that” conversations that derail good working relationships. (For more on structuring these, see my guide to roofing referral fee agreements.)

How to Structure Referral Arrangements So You Earn Fairly

Referring a lead to another roofing company is simpler than subcontracting. You do not manage the project, supply materials, or handle quality control on the job site. But you are providing something genuinely valuable: a qualified lead with a homeowner who needs work done and already trusts your judgment.

What referral fees look like in roofing

In residential roofing, a typical referral fee runs 5% to 10% of the total job value. On a $12,000 re-roof, that is $600 to $1,200 for a phone call and an introduction. Some roofers use a flat fee instead ($300 to $500 per closed job regardless of size), which is simpler to track but can leave money on the table on bigger jobs.

The fee only gets paid if the lead closes. That is standard in the trades and it is fair. You are not charging someone for a lead that goes nowhere. You are sharing in the revenue from a job that would not have happened without your introduction.

Getting paid consistently

The biggest problem with roofing referral fees is not the percentage. It is actually collecting the money. The receiving company finishes the job, gets paid by the homeowner, and then your referral fee is the last thing on their mind. If the arrangement is informal, it is easy for payments to slip.

I have found two things that help. First, a short written agreement that spells out the fee percentage and the payment timing: something like “within 14 days of receiving final payment from the homeowner.” Second, a simple way to track which leads you sent and what happened to them. If you are sending more than a handful of referrals a year, keeping track in your head stops working. A platform like PureIntro handles the tracking and payment coordination for exactly this kind of arrangement between trade professionals.

Building Your Network: Finding the Right Subs and Referral Partners

Whether you are looking for sub crews or referral partners, the process starts the same way: working alongside people and seeing what they produce.

Where to find sub crews

The best sub crews I have worked with came from three places:

• Crews I met on shared job sites. If you are doing a re-roof on a house where a siding crew is also working, you get to see their work ethic, their cleanup habits, and how they treat the property. That is a better interview than any conversation.
• Roofers who are scaling down. I know two guys who decided to stop running their own company but still wanted to work. They have years of experience, they know what quality looks like, and they are happy to run a crew under someone else’s name for a fair per-square rate.
• Supplier referrals. Your roofing supply house knows every contractor in the area. Tell your rep you are looking for a reliable crew for overflow work. They will not steer you wrong because your account is worth more to them than any single introduction.

Where to find referral partners

Referral partners are slightly different. You are looking for companies you trust with your customers, not crews you supervise. Start with roofers who serve a different niche or territory:

• A company that specializes in flat or commercial roofing if you focus on residential shingle and tile
• A roofer in an adjacent market area who covers zip codes you do not
• A company with a bigger crew that can handle the large jobs you turn down
• A roofer who focuses on repairs and maintenance if you only chase full replacements

The ideal referral partner is someone whose strengths complement yours, not someone who competes directly for the same jobs in the same area. When you refer work to a complementary company, both sides benefit. When you refer to a direct competitor, you are just feeding them leads in your own market.

A Side-by-Side Comparison: Subcontracting vs. Referring

Here is how the two models stack up across the factors that matter most to a residential roofing contractor:

• Revenue per job: Subcontracting earns you more per job (20% to 35% margin) vs. referring (5% to 10% referral fee). If maximizing revenue on a single job is the goal, subbing wins.
• Risk and liability: Subcontracting carries full warranty and liability risk. Referring carries none beyond reputational risk.
• Time commitment: Subcontracting requires site visits, material coordination, and schedule management. Referring requires a phone call or text.
• Scalability: Referring scales almost without limit. You can pass 20 leads a month with minimal effort. Subcontracting hits a ceiling based on how many crews you can supervise.
• Quality control: Subcontracting demands active quality oversight. Referring requires upfront vetting but no ongoing oversight.
• Customer relationship: Subcontracting keeps the customer in your orbit for future work. Referring transfers them to another company.

Neither model is universally better. Most established roofers end up using both, depending on the situation.

How I Use Both Models in Practice

Here is what my setup looks like today, after years of trial and error.

I have one sub crew I use regularly: a three-man team I have worked with for four years. They handle standard shingle re-roofs in my service area when my own crew is booked. I supply the materials, they bring the labor, and I visit every job at least once. That crew earns me an extra $3,000 to $5,000 a month during busy season without me spreading myself too thin.

I also have three referral partners. One does commercial flat roofing, one covers a neighboring county I do not service, and one runs a larger crew that takes on the big residential jobs I am not set up for. Between the three of them, I send out eight to twelve referrals a year. At $600 to $1,200 per referral, that is $5,000 to $15,000 in annual income for work I was going to turn down anyway.

The combination of both models means I never have to tell a homeowner “sorry, I cannot help you.” Every lead either stays under my name with a sub crew, or gets a warm handoff to someone I trust. Either way, the homeowner gets taken care of and I get paid.

Getting Started If You Do Not Have a Network Yet

If you are a newer roofing contractor or a solo operator who has been doing everything yourself, here is how to start building your network:

1. Start with one referral partner. Find one company in a complementary niche or adjacent territory. Send them a lead or two with no strings attached. Once they see you are sending real work, the conversation about a referral fee arrangement happens naturally.
2. Look for your first sub crew at the supply house. Ask your rep who is looking for overflow work. Meet the crew lead, check their insurance, and give them a small job first: a single tear-off, not a ten-job run.
3. Document the arrangement in writing. One page. The fee or rate, payment terms, quality expectations, and who is responsible for what. This prevents 90% of the problems that kill these relationships.
4. Start small and build trust. Give a new sub crew one job, inspect it thoroughly, and then decide if they get a second. Same with referral partners: send one lead, check in with the homeowner afterward, and see how the experience went. Trust is earned one job at a time.

The roofers who build the strongest businesses are not the ones who do every job themselves. They are the ones who know when to keep a job under their name, when to pass it to someone they trust, and how to get compensated fairly either way. Building that network takes time, but every solid relationship you develop is one more way to turn leads into revenue without overextending your crew.
