Cross-referrals between home trades: how a roofer, a plumber, a realtor and an insurance agent feed each other

Four businesses, one homeowner, a predictable order

A family buys a house in Lake Highlands. Before closing, their realtor orders an inspection that flags an aging water heater and a roof near the end of its life, and the lender requires proof of homeowners insurance. In the first year the water heater fails. In the third year a spring hailstorm hits the roof and the insurance agent is the first call. In the seventh year the family outgrows the house, and the realtor is back, asking which contractors can get it ready to list. Four businesses, one address, each handing the homeowner to the next whether they planned to or not.

I am Mantas Auk, a member of BNI Preston Center and the owner of a Dallas SEO agency, and from the search side I see this order constantly: a homeowner who searched "roofer" last month searches "homeowners insurance claim" this month and "realtor near me" a few years later. The businesses that do well are the ones that make the hand-off deliberate. BNI calls a group of complementary businesses that serve the same client without competing a power team, and BNI's own description uses real estate agents, home loan consultants, insurance advisors and movers as the example.

What follows is six scenarios, each showing who meets the homeowner first, what they notice, and who should get the introduction. The members in our chapter who hold these seats are the examples: Chris Grimes of Verde Roofing, Thomas Rhodes of 1-800 Plumber +AIR, Andy Scott of Dave Perry Miller in residential real estate, and Aaron Husman of The Phoenix Insurance for property and casualty coverage.

Scenario one: the inspection report lands on the realtor's desk

Every purchase produces an inspection report, and every inspection report is a list of referrals waiting to be made. The roof section says "serviceable, approaching end of life." The plumbing section notes a water heater past its expected service life and corrosion at the shutoff valves. The buyer asks the realtor one question: "Who do I call?" A realtor without partners says "search around." A realtor with partners says "I have a roofer and a plumber I trust; let me introduce you," and the buyer, who is already overwhelmed, is grateful.

The National Association of Realtors' 2024 Profile of Home Buyers and Sellers reports that 40 percent of all buyers found their agent through a friend, neighbor or relative, and 51 percent of first-time buyers did. Realtors live on referrals and understand them better than most trades, which makes them ideal partners if the trade holds up its end: showing up fast, speaking to the buyer with patience, and reporting back. The roofer who gives a buyer an honest "you have three to five years, here is what to watch" instead of a sales pitch has just become the realtor's roofer for every inspection that follows.

Scenario two: the roofer is on the roof and sees the rest of the house

Nobody sees a house the way a roofer does. From the ridge, the roofer sees gutters pulling away, a plumbing vent boot that has cracked, a chimney cap missing, the flashing around a bathroom exhaust fan rusted through. Inside the attic, the roofer sees the water heater flue, the HVAC ducting, and often the first signs of a leak the homeowner has not noticed. Every one of those observations is an introduction to another trade, if the roofer has the names and the habit.

A roofer who finishes the walk-around by saying "two things I noticed that are not my work: your vent boot is cracked and will leak eventually, and that water heater flue connection looks loose. I know a plumber who will tell you straight whether it is a problem" has done the homeowner a service and the plumber a favor. The plumber, in turn, is the one in the house a year later when the homeowner mentions the roof is leaking again. Trades that watch each other's backs on the same house keep each other busy between storms, which is the problem I wrote about in how home-service companies get steady work between the storms.

Scenario three: hail, the insurance agent and the roofer who plays by the rules

Hail is the season that makes or breaks this partnership in Dallas. After a storm, the insurance agent's phone fills with clients asking what to do, and the Texas Department of Insurance's after hail or windstorms guidance tells homeowners to file promptly, photograph the damage, make temporary repairs to keep rain out, get more than one bid, not pay in full up front, and avoid contractors who offer to waive the deductible. An agent who can say "here is a roofer who will follow every one of those rules and will not inflate the claim" protects the client and their own book.

The roofer's side of the bargain is the law. TDI's page on roofing and insurance states that it is illegal in Texas for a contractor to offer to waive, rebate or absorb a property policyholder's deductible, that contracts of a thousand dollars or more tied to an insurance settlement must include a notice that the policyholder must pay the deductible, and that insurers may request proof the deductible was paid. A roofer who builds those rules into the contract and explains them to the homeowner is the only kind an insurance agent can refer without risk. Chris Grimes wrote a homeowner's guide to how a hail claim actually works, and I would point any agent in Dallas to it.

The reverse referral is just as natural. The roofer meets homeowners whose claims went badly, whose coverage turned out to pay depreciated value on an old roof, or who are buying a house and have not thought about insurance. A sentence, "you might want an agent to look at how your policy treats the roof before next spring," is a referral to an insurance agent, and it comes at the exact moment the homeowner is paying attention.

Scenario four: the plumber finds the water damage and the insurance question

A supply line fails under a sink and the plumber is the first professional in the house. The plumber fixes the line and sees what the homeowner has not yet understood: the cabinet floor is swollen, the drywall behind it is wet, and the question of whether this is covered has not been asked. The plumber cannot answer the coverage question and should not try. The plumber can say "call your insurance agent before you do anything else, and if you do not have one you trust, I know one," and then suggest a restoration company, such as our chapter's Servpro of Park Cities, to dry the structure before mold starts.

The agent receives a client who called early, documented the damage and had the water stopped, which is the claim every adjuster wants to see. The homeowner receives a coordinated response instead of three disconnected phone calls. And the plumber receives, over the years, the agent's clients who need a plumber they can trust to show up and not overcharge, which is a steadier source of work than any amount of search advertising.

If you want to see these four seats together in one room, we meet every Thursday at 11:30 AM over lunch at Park City Club, 5956 Sherry Lane, Suite 1700, with open networking from 11:00 AM. Our chapter has one roofer, one plumber, one residential realtor and one property and casualty agent, which is the point of a one-per-category group: the circle in this guide is already sitting at the table.

Scenario five: the listing that needs to be ready in three weeks

When the family decides to sell, the realtor walks the house with a buyer's eyes and produces a list: a roof that will scare off inspectors, a slow drain in the guest bath, a water heater that will be flagged, and a question about whether the old hail claim was ever properly closed. The realtor needs a roofer who will give a fast honest assessment and, where it makes sense, a repair rather than a replacement; a plumber who will clear and certify the small items before the inspection finds them; and an insurance agent who can confirm the claim history and help the seller understand what a buyer's insurer will ask.

This is the scenario in which the realtor sends the most work and expects the most in return: speed. A listing has a calendar. A roofer who can be on site in two days and a plumber who can fit the small jobs in this week become the realtor's default, and a realtor's defaults are worth a lot of referrals a year, even when the first ticket is small.

Scenario six: the new owner, the policy and the first year

The circle closes where it started. The buyer who moved in has a new policy from the agent, who has their roof age and plumbing condition on file from the inspection. In the first year the agent is the professional with the most reason to check in, and the check-in is the natural moment to say "your inspection noted the water heater; if you want it looked at before it fails, here is the plumber my clients use." The agent becomes a coordinator of the homeowner's first-year maintenance, which is exactly the trusted role that keeps a policy from being shopped at renewal.

NAR's 2024 profile also reports that 88 percent of buyers would use their agent again or recommend them to others, and that 61 percent had already recommended their agent within the year. A realtor whose introductions to a roofer, a plumber and an agent all went well has given the buyer three more reasons to be in that 88 percent, and the trades have given the realtor three stories to tell the next buyer.

What each seat needs from the others

The scenarios suggest a short list of what makes a partner worth referring in each seat. Share it with your own circle, because most cross-referral relationships fail on an unspoken expectation rather than on bad work.

• The roofer needs honest introductions to homeowners whose roofs are actually aging, early word when storms produce claims, and partners who do not promise the homeowner a free roof.
• The plumber needs to be called at the first sign of a leak rather than after the drywall is down, and partners who describe the plumber as the one who shows up and tells the truth.
• The realtor needs trades that answer the phone within hours during a transaction, speak kindly to nervous buyers and sellers, and report back after the visit.
• The insurance agent needs contractors who follow Texas law on deductibles, document damage properly and never try to adjust the claim themselves, so the agent can refer them without a second thought.
• All four need the same thing from one another: a thank-you after every introduction and a note on how it turned out, so nobody is left wondering whether their client was looked after.

How to build the circle if you are starting from zero

Pick the seat you do not have. If you are a roofer with a good insurance agent and no realtor, the realtor is the first coffee to arrange, and the inspection-report scenario is what you talk about. Meet in person, ask what their ideal client looks like, and describe yours in one sentence. Then send the first referral yourself, before you receive one; the circle starts with whoever goes first.

A structured chapter shortens this considerably, because the seats are already filled by people who have agreed to send each other business and to report what happens. In ours, the roofer, the plumber, the residential realtor and the property and casualty agent see each other every Thursday, and the mortgage lender, the title company, the foundation contractor, the gutter company, the restoration company and the property manager are at the same table, which widens the circle described here into the whole house. If you hold one of these seats elsewhere in Dallas and want to see what a complete circle looks like before building your own, register on the Visit page and join us at Park City Club. Open networking begins at 11:00 AM, the meeting runs from 11:30 to about 1:00 PM, and the visitor orientation at the end will tell you whether your category is open.
