About
G3 Roofing & Construction is a roofing and restoration contractor based at 200 Mosswood Dr in Argyle, Denton County, serving the Dallas-Fort Worth metroplex. Owner Matt Alva founded the company after a 15-plus year career as a hospital and healthcare executive, with a stated mission to raise the bar in workmanship, support, and trust in the restoration profession. Its BBB profile records the business as started in January 2023, and it has been BBB accredited since April 2023 with an A+ rating. More than a roofer, G3 positions itself as a full restoration firm: residential and commercial roofing plus storm (hail and wind), water, fire and smoke, and mold work, along with window replacement, remodeling, and exterior services. The leadership team pairs Alva with JD Swenson, a chief operations officer with 14-plus years in construction and real estate development, and Jason Cook, who brings 11-plus years in catastrophic loss resolution. The company states credentials geared to insurance work, including HAAG Master Level inspector, IICRC certifications (AMRT, FSRT, WRT), a TDLR mold remediation contractor license, IAUA certified appraiser and umpire status, and Xactimate Level 3 training. The company operates under a Be Grateful, Be Generous, Be Good philosophy, committing to donate at least 10 percent of earnings to community causes, and states that roof replacements come with complimentary annual maintenance.

Insurance & credential verification
Texas does not issue a state roofing license, so we verify companies the way homeowners actually can: confirming insurance coverage, checking RCAT (Roofing Contractors Association of Texas) status, and checking city or county registration where the local jurisdiction requires one. Every credential below links to the actual issuing organization's own public lookup — don't just take our checkmark for it. Always ask for a current certificate of insurance before signing any contract.
Confirm this licence yourself at web.rcat.net/rcat/search — search #03-0630 or the company name.
Confirm this yourself: ask the company for their certificate of insurance (COI). Note that RCAT's Licensed Roofing Contractor credential (CRRL, RRL or CRL) is earned and held by a named individual at a company, not by the business itself, which is why we name that person above where we know it; Texas issues no company roofing license at all. RCAT and NTRCA status can be checked in their own public directories (RCAT, NTRCA) — use the "Licensed"/"Accredited" filter to see more than plain membership. GAF's contractor verification tool and Owens Corning's Texas locator confirm those tiers directly; CertainTeed doesn't offer a comparable self-serve lookup, so ask to see that certificate in person. BBB accreditation and rating are on bbb.org. Houston's own published registered-roofer list is years out of date, so it isn't cited here at all — confirm registration by contacting the city directly. Corpus Christi's STAR program has its own online contractor registry — for any other city or county registration claim, confirm directly with that jurisdiction's permit office.

Be careful with anyone that gives you nice discount because they are going to have to cut corners somewhere. You get what you pay for. Just finding this out the hard way. Now the included “lifetime labor warranty” only comes with excuses.
Mr. Gary, owner of 3 G ROOFING has been the best choice for me since 2012! Very responsive & everyone pays close attention to details! It’s now 2025 & they have done so much work for me on my referrals after my 1st project in 2012 & others since then! It’s now time for a new remodel project to be completed by 3/2026! I’m so ready for a surprise for my parent's to be executed!
I have been a 3G Roofing customer since 2021 when my house was hit with hail damage resulting in a $85,000 claim. Gary with 3G was exceptional dealing with the insurance company and getting them to revise their initial estimates, which were low with the insurance trying to repair things that obviously needed replaced. Every repair was completed well and when a subcontractor didn't do something to his standard, Gary had it corrected before I had even noticed anything so that the overall repair was exceptional. Later he replaced a roof at one of my dental office locations. Then he began working on remodel projects as well. 3G added a bedroom and changed a half bath to a full bathroom, remodeled and painted an entire dental office, and then updated paint and did several repairs at a 3rd location. Every project that I have hired 3G, Gary has made sure that it was done to a high quality. His communication with me has been excellent and he is always on top of projects. One of the best things is that a couple times when something needs tweaked after a project is completed, he will make sure it is fixed. Some places disappear on you once payment is complete and you can't get them back to fine tune the minor things. I highly recommend using 3G and have referred friends to 3G, all have said they had good experiences.
I recently had my roof replaced and Gary was great to work with. From the initial assessment of the damage to working with the insurance company to the completion of the work, everything went very smoothly. Gary helped to make sure any questions were answered promptly. The work was done very professionally and they did a great job from the beginning of the job to final cleanup. I would highly recommend 3G Roofing & Construction for any roofing needs. Thanks again for a great job!
In 2018 we received damage from a hail storm. I called 3G Roofing and spoke directly with the owner, Gary. He handled everything from start to finish. I was very impressed with how clean my yard and driveway were when the crew left. They took extra time to ensure every nail and piece of debris was picked up to my satisfaction before they left. The repairs included replacement of the roof and gutters. 3G handled all the repairs which made things easy for me. They are definitely a good choice.
