We Love Saving Roofs in Harlingen

We offer a free roof tune-up and 10% off for Military and First Responders.


My name is Darnell de Roulac. My wife and I were both born and raised in the Rio Grande Valley (RGV). I earned my Masters of Business Administration at the University of Texas Pan American. Upon graduation, I was commissioned as an officer in the United States Army and was deployed to Iraq in support of Operation Iraqi Freedom.

After 6 1/2 years of serving my country, I was honorably discharged and decided to further my education by becoming a Physical Therapist Assistant. During this time, I met my wife, Cristina, who is a Doctor of Physical Therapy.

We both have enjoyed helping our patients regain strength and mobility in order to improve their overall quality of life.

On our free time, we enjoy running, taking our kids to South Padre Island, working outdoors, and watching our kids participate in extracurricular activities.

As faith would have it, we were introduced to Roof Maxx and knew right away this was the business for us. This business has allowed us more time to spend raising our 4 beautiful children while also offering the RGV a roof replacement alternative.

We believe in the product and we love saving people money especially in this current economy. We cherish the idea of reducing waste and protecting the environment. We are thankful that being a small business owner has allowed us to preserve the values of Faith, Family and Community.

We serve Willacy, Cameron, Hidalgo and Starr County.

How Does Roof Maxx Benefit You?

Asphalt shingles aren't what they used to be. In fact, they include less asphalt than they once did, so they dry out and fail faster than ever before. Fortunately, Roof Maxx's revolutionary new technology uses natural plant based bio-oil to restore shingles' flexibility and instantly add five years of life to a roof. With three treatments possible, once every five years, Roof Maxx adds up to 15 years of added life to your asphalt roof.

How Much Will Roof Maxx Cost You?

Roof Maxx can save you up to 80% over a roof replacement. How would you like to save thousands with a Roof Maxx treatment? The exact cost will depend on the size of your roof. Our Roof Maxx dealers will give you an exact quote after you fill out our Get Free Estimate form.

It All Adds Up

How do I know if my roof is ready for Roof Maxx?

Asphalt shingles contain small, sand-like pebbles that stick together when shingles natural oils are intact. Once those oils start to dry out with age, you may see the granules flaking off in your gutters or downspouts. You might also notice black stains and streaks or shingles cracking, breaking, and curling. Since each roof is different, your local dealer will perform a free inspection to tell if Roof Maxx can help you.
