Roof Coating in Davis, CA

What Roof Coating Does

A reflective coating system works by creating a seamless, flexible membrane across your entire roof surface. Unlike shingles or tiles, coatings bond directly to your substrate—whether asphalt, metal, concrete, or flat membrane. The elastomeric coating stretches and contracts with temperature swings (Davis sees 90°F+ afternoons and cool mornings), so it doesn't crack or separate. Silicone coatings excel at shedding ponding water, while acrylic elastomerics offer cost-effective UV protection and energy savings.

We start with a thorough roof condition survey. Our crew inspects for alligatoring (cracked, checkered patterns), delamination (layers separating), erosion of granules, and any seams or flashing that need attention. We document everything—photos, measurements, material recommendations—so you understand what's being repaired before we begin.

Materials We Use

Silicone coatings handle ponding water better than most alternatives; they cure slowly but create exceptional tensile strength and flexibility. Acrylic elastomerics dry faster and cost less upfront, though they need recoating every 5–7 years. Polyurethane coatings offer superior abrasion resistance if foot traffic or HVAC maintenance is common on your roof. Each system includes a primer layer that bonds to the old surface, then a repair coat (thicker, patched areas), and finally a finish coat (the visible, reflective layer). We apply everything with roller application or airless sprayer, depending on roof size and geometry. The dry film thickness matters—we target 20–30 mils to ensure durability and warranty coverage.

A squeegee is essential for working out air pockets and ensuring even adhesion, especially at seams and flashing bead details where water loves to hide. Proper substrate prep—cleaning, priming, and patching—is non-negotiable; a coating is only as good as what it's bonded to.

Why Davis Roofs Need Coating

Davis summers are relentless. Intense UV exposure degrades asphalt shingles and oxidizes metal roofs year after year. Winter rain and occasional heavy downpours test every seam and flashing. By the time you notice leaks inside, water has already wicked through cracks and damaged the decking. A reflective coating stops that cycle. It reflects 65–85% of solar heat, cutting cooling costs by 10–20%. It seals micro-cracks before they become structural problems. And it buys you 10–15 years without a full roof replacement—a major financial difference.

The Application Process

Step 1: Inspection & Prep – We walk your entire roof, identify all damage, and create a detailed estimate. We photograph alligatoring, delamination, pooling areas, and flashing issues. Prep includes power washing, patching holes, and allowing 24–48 hours for the substrate to dry completely.

Step 2: Primer Application – We apply a primer coat that bonds the new coating to your old roof. This step is skipped by cut-rate contractors and is why their coatings fail. We don't skip it.

Step 3: Repair Coat – High-build repair coat goes down over damaged seams, flashing, and any area that needs extra protection. This is where the squeegee work happens—we hand-work every seam to eliminate air pockets and ensure full adhesion.

Step 4: Finish Coat – The reflective finish coat is applied uniformly across the entire roof. Coverage rate varies by product (typically 300–400 sq ft per gallon), and we always apply two coats for maximum durability and warranty compliance.

Step 5: Cure Time & Inspection – Most coatings cure in 24–72 hours, depending on humidity and temperature. We schedule a final walkthrough, photograph the completed work, and provide you with warranty documentation and maintenance recommendations.

Cost & Warranty

A typical 2,000 sq ft residential roof costs $2,500–$4,500 for a two-coat silicone system, or $1,800–$3,200 for acrylic elastomeric. Flat commercial roofs often cost less per square foot due to scale. Pricing depends on roof condition, slope, seam count, and material choice. We provide free estimates and work with most insurance carriers if storm damage is involved. Warranties typically run 10–15 years for materials and labor, transferable to the next owner.

Energy Savings & Sustainability

Reflective coatings reduce roof surface temperature by 40–60°F on a 95°F day. That means your HVAC runs less, your utility bill drops, and your roof lasts longer. No tear-off means no landfill waste—we're reusing your existing structure, which is the greenest choice available. Over 15 years, the energy savings often pay for the coating cost entirely.

When You Need Coating

Signs include visible blistering (bubbles in the membrane), widespread cracking, seams that leak during rain, ponding water that doesn't drain, or shingles with heavy granule loss and UV degradation. If your roof is 10–15 years old and still structurally sound, coating is often the right answer. If decking is rotted or sagging, you'll need repair or replacement first.
