6 Reasons Why You Can Trust Desert Sun for Your Elastomeric Roof Coating Project
If you were to ask a handful of roofers in Pima County how to handle a flat roof, you would probably get a wide range of conflicting advice. In an industry crowded with generalists who bounce from shingles to tiles, finding a clear, definitive answer for a horizontal surface can feel exhausting.
At Desert Sun Roofing, we believe that true trust isn’t built on a broad sales pitch—it’s built on a singular focus. We do not work on shingles, we do not lay tile, and we do not handle residential slope replacements. Our entire business is dedicated to a single, specialized craft: protecting and extending the life of flat roofs using premium elastomeric roof coating systems. When a team pours 100% of its daily energy, training, and experience into mastering flat surfaces, the result is a level of precision and honest guidance that generalized companies simply cannot duplicate.
We’ve been in business since 2007, working tirelessly to build our sterling reputation here in Tucson. If you are looking for the right team to safeguard your home before the next monsoon season arrives, here are the 6 definitive reasons why you can trust Desert Sun Roofing with your flat roof, driven directly by our strict, field-tested installation standards.
1. Absolute Specialization in Elastomeric Roof Coating
The physics of a horizontal roof are entirely different from a sloped shingle or tile roof. Water drains differently, UV radiation hits more intensely, and structural movement is much more pronounced. Because we only do flat elastomeric roof coating, our crew members aren’t multi-tasking general laborers—they are specialized technicians who understand the exact chemistry required to make a horizontal surface completely watertight.
We know the precise advanced polymer formulations for elastomeric roof coating that performs best under the blazing Arizona sun. We choose premium products engineered for high elongation, meaning the cured rubber membrane can stretch up to 300% or more without tearing and seamlessly snap back to its original shape. This specialization means we diagnose hidden issues faster and prescribe solutions that actually last.
2. Meticulous Roof Cleaning Process
You might assume that thoroughly clearing a surface before sticking a permanent, waterproof membrane to it is standard practice across the industry. Unbelievably, it is not. There are generic roofing companies in Tucson that will roll a fresh coating directly over loose, failing material just to save a few hours of labor.
At Desert Sun Roofing, we start every project with a rigorous, two-step structural clean. First, we clear all loose debris from the roof surface and trim back any overhanging tree limbs or desert bushes interacting with your roofline to prevent immediate physical scraping. Second, we hand-scrape away all existing loose or peeling roof coating from the surface, meticulously bagging and removing the debris so the substrate is entirely sound.
3. Precision 3200 PSI Chemical-Free Deep Washing
Once the loose material is gone, the baked-on “desert crust” of fine silt, dust, and environmental residue must be completely eradicated. Coating over a dusty roof prevents the new layer from binding to the actual structure, leading to rapid bubbling and peeling. Our standard protocol requires deeply cleaning the roof surface with a 3200 PSI chemical-free high-pressure wash. Utilizing exactly 3200 PSI provides the precise physical force needed to strip away microscopic dirt layers and open up the pores of the substrate for maximum adhesion, completely eliminating the need for harsh chemical agents while ensuring the underlying roof structure suffers absolutely no physical damage.
4. Comprehensive Metal and Penetration Reinforcement
A flat roof is highly vulnerable at its edges and penetration joints, where different materials meet and expand at different rates under the desert heat. Before any liquid coating is poured, we systematically secure and reinforce these high-stress areas.
We mechanically secure any loose metal drip edges, metal roof flashings, and rooftop fixtures so they cannot shift in high monsoon winds. Following that, our technicians seal around all roof penetrations—including pipes, electrical lines, and vents—using a heavy-duty, rubberized roof flashing compound that maintains an airtight, elastic bond over years of structural shifting.
5. Advanced Three-Course Scupper and Crack Fortification
The drainage entry points and existing stress fractures require far more than a simple layer of paint. Water flows with immense volume through drainage zones, and micro-cracks will quickly tear a standard coating layer apart during a sudden temperature drop.
To solve this, we execute a rigorous 3-course detail on all roof scuppers and every single visible roof crack using a premium rubberized roof flashing compound. This “three-course” methodology involves sandwiching a high-tensile reinforcing fabric membrane between two thick layers of rubberized flashing mastic. This creates an incredibly durable, reinforced joint that can easily absorb intense structural movement without leaking.
6. Tailored Priming, Dual-Coat Thickness, and Structural Care
We tailor our chemical process directly to the unique needs of your roof’s surface. If your specific substrate shows signs of heavy aging, we lay down a foundational roof primer coat using Tucson Rubberized premium clear primer (#297-X) to maximize chemical cross-linking. Furthermore, if your roof exhibits persistent ponding areas where water struggles to drain, we embed a specialized tie-tex membrane to give the system heavy-duty structural reinforcement. We also inspect and replace any damaged or broken skylight domes as needed to ensure the entire system is renewed.The actual coating process is built on maximum thickness and durability. We never cut corners with a single “thick” layer, which fails to cure correctly. We apply a full first coat of premium, high-quality Tucson Rubberized Coating. Most roofing companies will use #7000. We only use #10000, it’s more expensive but a superior quality. Once that initial layer has fully cured and formed its base matrix, we apply an identical second full coat to lock in a massive, seamless, monolithic wear layer. When the seals are set, we completely clean up and remove all project debris from the job site, leaving your home or business just as clean or cleaner than when we first arrived.
Frequently Asked Questions
Q: Can any flat roof be saved with an elastomeric roof coating?
A: Most flat roofs in Tucson are excellent candidates for a elastomeric roof coating. However, if a roof has been neglected for so long that the underlying wood structure is rotted from trapped moisture, a coating cannot structurally fix that issue. We will always give you an honest evaluation of whether your roof deck is healthy enough for a coating.
Q: How often should roof coatings be reapplied?
A: Generally, a high-quality, professionally applied elastomeric roof coating should be reapplied every 3 to 5 years. Factors like extreme desert heat, proper drainage, and keeping the surface free of dirt and debris can impact longevity. The great advantage of this system is that you can indefinitely extend the life of your roof by simply applying a fresh top coat before the existing layer wears down to the substrate.
Q: Is elastomeric coating the same thing as white roof paint?
A: No, they are entirely different. White reflective paint is thin and dries rigid, meaning it will crack the first time the roof expands from the heat. An elastomeric roof coating is a heavy-duty compound that stays flexible, thick, and rubberized for over a decade.
Q: Does roof coating help lower energy bills?
A: Absolutely. A premium white elastomeric roof coating will act like a mirror for your home by reflecting up to 85% of solar radiation away from the roof deck. Because a flat roof sits horizontally under direct sunlight all day, keeping that surface cool significantly reduces the workload on your air conditioning system, often lowering monthly summer cooling costs by 15% to 20%.
