Step 1: Inspection and Cleaning
We begin with a comprehensive roof assessment to evaluate structural integrity, identify potential problem areas, and determine the most suitable coating system for your specific roof type. Our team examines drainage patterns, looks for signs of membrane deterioration, and checks for loose fasteners or damaged flashing.
Following inspection, we perform thorough surface preparation using power washing, scraping, and specialized cleaning equipment to remove all dirt, grease, oxidation, and loose materials. This cleaning process is crucial because contaminants prevent proper coating adhesion and can lead to premature failure.
Step 2: Repairs
Surface preparation continues with detailed repair work addressing every identified deficiency before coating application. We seal all cracks using compatible sealants, replace damaged membrane sections, and reinforce problem areas with fabric reinforcement where necessary. Seam repairs receive special attention, as these areas are most vulnerable to water infiltration.
We also address any ponding water issues by improving drainage or adding tapered insulation systems. All repairs are allowed to cure completely before proceeding, ensuring a stable foundation that won't compromise the coating's performance over time.
Step 3: Primer Application
Primer application creates the critical bond between your existing roof surface and the new coating system. We select primers specifically formulated for your roof material and chosen coating type, ensuring optimal chemical compatibility and adhesion strength. The primer is applied using spray equipment or rollers depending on surface conditions and manufacturer specifications.
We pay particular attention to achieving uniform coverage and proper mil thickness, as inadequate priming leads to coating delamination and reduced system performance. Weather conditions are carefully monitored during this phase, as temperature and humidity directly affect primer adhesion and curing.
Step 4: Coating Application
The final coating application requires precision timing and expert technique to achieve uniform thickness and seamless coverage across the entire roof surface. We use professional-grade spray equipment calibrated to deliver consistent mil thickness while avoiding over-application that wastes material and under-application that compromises protection.
Multiple coats may be applied depending on the coating system specifications and roof conditions. Each coat is allowed proper cure time before applying subsequent layers, and we continuously monitor weather conditions to ensure optimal application conditions.
Frequently Asked Questions
Maintaining a roof coating properly extends its life and ensures optimal performance. Routine inspections and timely addressing of minor issues help protect your investment.
How much does roof coating cost in Glendale?
Roof coating costs in Glendale typically range from $3 to $7 per square foot, making it significantly more affordable than roof replacement. For an average-sized home, expect to invest between $3,000 and $8,000 depending on your roof's size, condition, and the coating type selected. Factors affecting price include surface preparation needs, number of coats required, and material choice. Most homeowners find roof coating pays for itself within 3-5 years through energy savings and extended roof life.
What type of roof coating is best for flat roofs?
Silicone roof coating performs exceptionally well on flat roofs due to its superior waterproofing properties and resistance to ponding water. Unlike other coatings, silicone maintains flexibility in temperature extremes and provides excellent UV protection. Acrylic coatings work well for flat roofs in good condition but may not handle standing water as effectively.
Can you apply roof coating over shingles?
Yes, roof coating can be applied over asphalt shingles, but proper preparation is essential for optimal results. The shingles must be in good structural condition without loose, curled, or missing pieces. Our team thoroughly cleans the surface, repairs any damaged areas, and applies primer when necessary to ensure proper adhesion. However, severely deteriorated or very old shingles may require replacement rather than coating. A professional inspection determines whether your shingle roof is a good candidate for coating application.
Does roof coating work in Glendale heat?
Roof coating performs excellently in Glendale's intense heat and actually helps combat high temperatures. Quality roof coatings reflect solar radiation, reducing roof surface temperatures by 50-80 degrees compared to uncoated roofs. This reflective property significantly reduces cooling costs during hot summer months. Silicone and acrylic coatings are specifically formulated to withstand UV exposure and thermal cycling without cracking or peeling.
Can I stay in my home during roof coating?
Yes, you can remain in your home during roof coating application. The process typically doesn't require access to your living spaces, and most work is completed from the exterior. You may notice some noise during surface preparation and application, but it's generally less disruptive than other roofing projects. We recommend keeping windows closed during application to minimize odors from coating materials.
