What Roof Coating and Waterproofing Delivers for Your Property

Roof coating and waterproofing is a targeted, cost-effective service that applies a seamless protective layer across the entire surface of an existing roof, sealing small cracks and seams, eliminating exposed fastener penetrations as potential water entry points, and creating a continuous waterproof barrier that prevents infiltration. Unlike spot repairs that address specific damaged areas, a full coating application treats the entire roof surface as a system, closing vulnerabilities you may not even be aware of yet.

For commercial and residential flat roof owners in Richfield, WI, a roof coating applied to a roof that is structurally sound but showing surface deterioration is frequently the most economical path to another decade or more of reliable performance. The alternative, a full tear-off and membrane replacement, costs significantly more and generates substantial waste. A coating applied correctly with proper surface preparation can deliver equivalent waterproofing performance at a fraction of the replacement cost.

Beyond waterproofing, reflective roof coatings deliver meaningful energy performance benefits. A standard low-slope commercial roof with a dark membrane surface can reach temperatures of 150 to 180 degrees Fahrenheit on a hot summer day in Richfield, WI, driving significant heat gain into the building below. A white or light-colored reflective coating can reduce roof surface temperatures by 50 to 70 degrees Fahrenheit, directly reducing cooling loads and energy costs throughout the summer months.

Coating Is Not a Substitute for Repair

A coating system will not fix an actively leaking roof or compensate for failed seams, blistered membrane sections, or saturated insulation beneath the surface. All underlying deficiencies must be identified and repaired before any coating is applied. Troy Bass Roofing Solutions always begins with a thorough inspection and completes all necessary repairs before applying any coating system. This preparation phase is what separates a lasting coating installation from one that fails prematurely.

Coating Systems We Install

Most Popular

Elastomeric Acrylic Coating

The most widely applied residential and light commercial roof coating. Water-based acrylic elastomeric coatings are flexible enough to bridge minor surface cracks, highly reflective when applied in white or light colors, and compatible with most existing roofing surfaces. They are the most cost-effective entry point into roof coating and are suitable for most metal, modified bitumen, and SPF roofing surfaces in Richfield, WI.

Premium

Silicone Roof Coating

Silicone coatings are the premium choice for flat roofs in areas that experience prolonged standing water. Unlike acrylic coatings that can soften under ponded water conditions, silicone maintains its waterproof integrity regardless of how long water remains on the surface. Silicone also provides outstanding UV resistance and does not chalk or degrade as quickly as acrylic alternatives under intense sun exposure.

Industrial

Polyurethane Coating

Two-component polyurethane coatings provide the highest level of abrasion resistance and tensile strength of any roof coating system. They are the appropriate choice for roofs that receive significant foot traffic, mechanical service access, or equipment load. Polyurethane systems are also used on roofs with complex geometries where a higher-build film thickness is needed to protect transitions and detail areas.

Metal Roofs

Aluminum Reflective Coating

Aluminum-pigmented coatings are specifically formulated for metal roofing surfaces. They provide excellent UV protection that slows the oxidation of metal panels, reduce thermal movement-induced fatigue at seams and fastener points, and deliver meaningful reflective performance that reduces cooling loads in metal-roofed commercial buildings and residences across Richfield, WI.

Key Benefits of Professional Roof Coating

  • 🌡️
    Significant Energy Cost Reduction: Reflective white and light-colored coatings reduce roof surface temperatures by 50 to 70 degrees Fahrenheit compared to dark membrane surfaces. This directly reduces the heat gain transferred into the building below, lowering air conditioning loads and energy costs throughout the cooling season in Richfield, WI.
  • 💧
    Seamless Waterproof Membrane: Unlike roofing materials installed in lapped sections that create seams and overlaps, a spray or roll-applied coating forms a seamless continuous membrane across the entire roof surface. There are no joints, laps, or fastener holes in the coated area to become entry points for water.
  • 🔧
    Minimal Disruption During Application: A roof coating installation is far less disruptive than a tear-off and replacement. The existing membrane remains in place, the structural system is not disturbed, and the installation typically generates minimal noise and no debris hazard for building occupants or visitors.
  • ♻️
    Environmentally Responsible: Applying a coating system over an existing roof avoids generating the significant volume of tear-off debris that a full replacement creates. For environmentally conscious building owners and commercial operators, the reduced waste footprint of a coating project is a genuine advantage.
  • 📅
    Postpones Replacement Capital Expense: For commercial property owners and residential investors managing capital budgets, a properly applied coating system that extends roof service life by 10 to 20 years represents a significant postponement of the full replacement capital expense, allowing those funds to be directed to other priorities in the interim.

Our Coating Application Process

01

Full Roof Inspection and Deficiency Report

We perform a systematic inspection of the full roof surface, documenting all areas of damage, failed seams, blistering, ponding zones, and flashing deficiencies. You receive a written report of all findings and a clear picture of what must be repaired before coating proceeds.

02

Surface Preparation and Cleaning

The entire roof surface is pressure-washed or chemically cleaned to remove all dirt, chalk, mildew, oxidation, and contaminants that would prevent proper coating adhesion. Proper surface preparation is the single most important factor in coating performance and longevity.

03

Deficiency Repair Before Coating

All identified deficiencies are repaired prior to coating application. This includes seam repairs, flashing re-sealing, blister remediation, and fabric reinforcement at all critical transition details. No coating is applied over surfaces that have not been restored to a sound condition.

04

Coating Application at Specified Rates

The selected coating is applied in the required number of coats to achieve the specified dry film thickness needed for the warranty program and performance objectives of the project. Critical details receive additional mil build to ensure superior coverage at seams, flashings, and penetrations.

Roof Coating and Waterproofing FAQ

What types of roofs are best suited for coating application?

▾
Roof coatings are most effective on flat and low-slope roofing systems including TPO, EPDM, modified bitumen, built-up roofing, and spray polyurethane foam surfaces. Metal roofing, both standing seam and exposed fastener panel systems, is also an excellent candidate for coating application, particularly for corrosion protection and energy efficiency improvement. Steep-slope shingle roofing is generally not a suitable candidate for liquid-applied coating systems because these surfaces are designed to shed water by slope rather than by membrane, and the coating would not adhere consistently across the overlapping shingle surfaces. For shingle roofs showing age, our recommendation is typically a targeted repair program or eventual full replacement rather than a coating approach.

How long does a roof coating application take to complete?

▾
The duration of a coating application depends on the size of the roof, the number of coats required by the specified system, the drying and recoat time between applications, and the weather conditions during the project. Most residential and small commercial coating projects in Richfield, WI are completed within one to three days of active application work, not counting the inspection and repair phase that precedes coating. Larger commercial roofing surfaces covering tens of thousands of square feet may take five to ten days or more depending on the system and crew deployment. We provide you with a realistic project timeline at the proposal stage so you can plan accordingly. Coating application requires dry weather conditions, and we monitor forecasts closely to schedule work during appropriate windows.

Can a coating system be reapplied when it eventually wears out?

▾
Yes, and this is one of the most compelling long-term advantages of a coating-based roof maintenance program. When a coating system approaches the end of its service life, the surface can be cleaned, any new deficiencies repaired, and a fresh maintenance recoat applied at a significantly lower cost than the original coating installation. This recoat cycle can theoretically extend the service life of the underlying roof indefinitely, as long as the primary membrane and deck remain structurally sound. Several coating manufacturers offer maintenance programs that include scheduled inspections and recoat cycles as part of an extended warranty package. Troy Bass Roofing Solutions can discuss which programs are available and applicable for your specific roof system and help you plan a long-term maintenance approach that maximizes the return on your roofing investment.
