Training & Ongoing Support

You don’t need to know how to nail shingles to own a Brennan Roofing location. You need to know how to run a disciplined business, and that’s what we teach. Since 2000, the Garrison Partners family has built a training system that takes people from completely green to fully operational. Every owner goes through the same program before their first truck rolls, and the support doesn’t stop after launch. The roofing knowledge comes with the territory. The systems, the pricing discipline, the hiring process, the vendor relationships – that’s what we hand you on day one.

Initial Training

Week one through launch, we teach you the trade from the ground up – but we teach it as an owner, not as a roofer. You’ll learn roofing terminology so you can talk to suppliers without getting lost: decking, underlayment, flashing, ridge vents, drip edge. You’ll learn how to read a roof, spot failures, and understand what actually causes leaks so you can price jobs honestly and explain them plainly. We walk you through the software that runs the business: our CRM, scheduling, the point-of-sale system that generates the written price before any work starts, and the reporting you’ll use to track jobs. Hiring comes next – how to find the right crews, how to vet them, what background checks look like, and how to keep them accountable to The Garrison Code. Then we cover the money side: margin targets, material costs, labor rates, and how to price a job so you’re competitive without cutting corners. You’ll leave training knowing how to run a roofing company, not just how to replace a roof.

Launch Support

Opening the doors is when most new owners feel the weight of it. We’re there with you. Our launch team helps you set up your local market from the ground up: the website, the Google Business Profile, the local listings, the service area mapping. We get your phone ringing with a lead engine that’s already been tested across the Garrison Partners family – not a pile of marketing theory, but actual campaigns that produce calls in roofing markets. When the first jobs come in, a field coach rides along. You don’t run your first estimates alone. We’re on the phone with you after, walking through what went right and what to tighten up. The goal is simple: the first five jobs a new owner runs should feel like the hundredth. And every one of those first jobs gets a written price before work starts, because that rule doesn’t bend for anyone, including a new owner still learning the rhythm.

Ongoing Support

Training doesn’t end at launch. The support structure is built to be there the entire time you own the location:

  • Field coaching – Regular site visits and ride-alongs from experienced operators who’ve run roofing crews. They watch your estimates, your installs, and your cleanup, and they tell you straight what needs fixing.
  • Ongoing marketing support – Your local campaigns are managed with you, not for you. We review performance monthly, adjust spend, and test new channels as roofing demand shifts through the seasons.
  • Vendor relationships – You buy materials through established lines with GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral. The pricing is already negotiated. You don’t start from scratch cold-calling supply houses.
  • Technology updates – The software stack that runs the business gets maintained and updated centrally. When there’s a better way to schedule crews or track job costs, you get it without having to shop for it.
  • National brand campaigns – Garrison Partners runs brand-level marketing that supports every location. You get the halo of a recognized name without carrying the whole budget yourself.
  • Peer network – You’re not the only owner in the family. When a weird roof situation comes up – and it will – there’s a group of owners who’ve seen something like it before. You can pick up the phone and ask.

You’re Never Alone

This is a franchise built on discipline, not on leaving owners to figure it out alone. If you want to know what training looks like in detail, call (361) 320-9467 or request more information below. We’ll walk you through it.
