FAQs
What makes your high-performance roof coatings ideal for metal roofs in Blaine’s climate?
Our elastomeric and silicone-based coatings are engineered to flex with the daily freeze-thaw cycles and temperature swings common to Blaine. They form a seamless, UV-stable membrane that resists corrosion, ponding water, and wind-driven rain—issues that frequently shorten the life of untreated metal roofs in Minnesota’s harsh weather.
How long can I expect a coated metal roof to last compared with an uncoated roof?
A properly prepared and coated metal roof can extend service life by 15–20 years or more. The coating seals fasteners, joints, and micro-cracks, preventing rust and water infiltration that typically cause metal panels to fail after 20–25 years. Many clients in Blaine see total roof lifespans of 40 years or longer once the coating system is applied and maintained.
Will a roof coating help lower my energy bills?
Yes. Our high-albedo white and light-gray coatings reflect up to 85% of solar heat, keeping attic and interior temperatures cooler in summer. Independent studies show reflective coated roofs can reduce Blaine homeowners’ cooling costs by 10–25%, and commercial facilities often qualify for local utility rebates tied to energy-saving cool-roof technologies.
What is the installation process for coating an existing metal roof?
1) Inspection & moisture scan – we locate and replace any compromised panels or wet insulation. 2) Surface prep – pressure-wash at 3,500 psi, remove oxidation, and treat rust with a phosphatizing primer. 3) Seam & fastener treatment – embed polyester fabric in a base coat over all transitions and tighten or replace screws. 4) Application – spray or roll the high-performance coating at 1.5–2 gal per 100 sq ft for uniform 20-mil dry film thickness. 5) Final inspection – verify adhesion, thickness, and watertightness before issuing the manufacturer’s warranty.
How much does high-performance coating cost versus full roof replacement?
In Blaine, coating a metal roof typically runs $3–$6 per square foot, depending on prep requirements and total square footage. Full tear-off and replacement of a metal roof can cost $9–$14 per square foot. Coating therefore saves 40–60% upfront and qualifies as a maintenance expense rather than a capital improvement, offering tax advantages for commercial property owners.
What maintenance is required after my metal roof is coated?
Maintenance is simple: schedule an annual inspection, clear debris from gutters and valleys, and wash the roof every 2–3 years with a low-pressure rinse to remove dirt that can reduce reflectivity. If mechanical damage occurs—e.g., from falling branches—our team can perform spot repairs that seamlessly tie into the original membrane, preserving your warranty for its full term.
