Franchise Investment Overview
If you’re reading this, you’re probably not shopping a franchise the way you’d shop a truck. You want hard numbers, or at least honest ranges, before you waste a month on brochures. So here’s the straight version. What follows are the realistic costs to open a Brennan Roofing location, based on what it actually takes to run a residential roofing company. These are ballpark marketing estimates. Nothing here is a legal offer, and we don’t do handshake math. We do written numbers, and we expect you to hold us to them. That discipline is the whole point of the brand.
Estimated Startup Investment
The table below reflects what a new owner typically commits to stand up a Brennan Roofing operation with a truck or two on the road, a small office, and enough runway to get through the first season. Ranges exist because markets differ. A location in a mid-size metro will carry different lease and labor costs than a smaller suburb. What doesn’t change is that every number gets put in writing before anything is signed.
| Investment Category | Estimated Range |
|---|---|
| Franchise Fee | $45,000 – $65,000 |
| Equipment & Vehicles | $60,000 – $110,000 |
| Initial Marketing & Launch | $25,000 – $45,000 |
| Working Capital (first 6 – 12 months) | $70,000 – $120,000 |
| Total Estimated Investment | $200,000 – $340,000 |
Those ranges are built from the trade itself. Roofing is equipment-heavy from day one. Ladders, safety gear, a dependable work truck or two, nail guns, tear-off tools, and a trailer add up fast. We’d rather you see that number up front than discover it six months in. The franchise fee is what buys you the brand, the systems, and the training. It does not include your operating capital, and it should not. You need real money behind you to run a real company.
What’s Included
When you write the franchise fee check, here’s what it actually pays for. Not promises. Not a binder of “proprietary secrets.” Just the things a new owner needs to open the doors and run the business the way Brennan Roofing is supposed to be run.
- Brand license and the Brennan name. Brennan is an old Irish surname. Easy to say on the phone, and it sounds like a company that has been on the roof for years. You get the right to use it, along with the marks and the promise attached to it.
- The Garrison Standard training program. Before you take your first job, you and your crew lead learn how we bid, how we schedule, how we inspect, and how we close out a site. This is the operational backbone of the company.
- Launch marketing support. A new roofing company has to be findable. We help you set up your local presence, from signage and vehicle wraps to your initial online footprint, so you’re not cold-calling your way through month one.
- Operational systems and pricing tools. The written-price-before-work-starts rule is not a suggestion. We give you the estimating framework that makes it repeatable, so your numbers are consistent from job one.
- Territory rights. You operate as an independent local business with a defined service area. Garrison Partners does not pretend to be from every town. Each location is an independent business that agreed to work to The Garrison Standard. Your territory is yours to build.
- The 365-Day Done Right Promise backing. You’ll be able to offer the same written guarantee every Brennan Roofing location carries: if a repair or installation fails within one full year, we come back and make it right at no charge. That promise is part of what you’re buying.
Financing & Next Steps
This is a capital-intensive business, and most owners don’t bring the full amount in cash. That’s normal and expected. Third-party financing is commonly available for equipment, vehicles, and portions of the startup cost. Traditional bank loans, SBA-backed lending, and equipment financing through commercial lenders are all routes our owners have used. We don’t lend money ourselves, and we don’t make financing decisions for you. What we do is give you a clear picture of what the buildout costs so you can take a real set of numbers to your bank or lender and have a grown-up conversation.
From here, the process is simple. You call us, we talk. We’ll ask where you’re looking to operate, what kind of capital you’re working with, and whether you’ve run a trade business before. If it makes sense for both sides, we send you the qualification materials. That’s where the exact figures come from, not from this page. Call (361) 320-9467 and ask for the franchise investment kit. A live person answers. No voicemail, no automated system, no callback queue. That’s how we run the roofing business, and it’s how we run the franchise conversation too.
All figures on this page are non-binding marketing estimates for planning purposes only. Actual investment amounts vary by market, territory size, and individual circumstances. Official figures are provided in the qualification documents after you speak with our team.
