If your metal roof is structurally sound but showing rust, loose fasteners, or tired paint, a professional metal roof coating can add years of service life without a full tear-off. Coatings create a seamless, flexible membrane over the panels that helps seal seams and fasteners and reflects summer heat.
Custom Remodeling LLC applies metal roof coatings on shops, barns, warehouses, churches, and commercial buildings throughout DeSoto County and the Memphis metro. We'll tell you honestly whether your roof is a good coating candidate or whether replacement makes more sense.

- Inspection to confirm the roof is a good coating candidate

Coating options
Acrylic coatings
Cost-effective, highly reflective — popular for heat reduction.
Silicone coatings
Excellent resistance to ponding water and UV exposure.
Elastomeric systems
Flexible coatings that move with panel expansion and contraction.
Color choices
White and light colors reflect the most heat; other colors are available.
Signs a metal roof coating could help
- Surface rust spreading across panels
- Loose or backed-out fasteners
- Faded, chalky paint
- Seams that are starting to let water in
- High cooling bills in a shop or warehouse

Most metal roof coating projects take two to five days depending on size and prep needed, with dry weather required for application. We schedule around the forecast to make sure each coat cures properly.
Metal Roof Coatings FAQ
Is my metal roof a good candidate for coating?
Roofs with surface rust and sound panels are usually good candidates. Panels with holes rusted through or major structural issues may need replacement instead.
Will a coating lower my cooling costs?
Reflective coatings can reduce the heat absorbed by the roof, which may help lower cooling costs in shops and commercial buildings.
Can coatings be applied to residential metal roofs?
Yes, though they're most common on commercial and agricultural buildings. We'll discuss whether it's a fit for your home.
How long does a metal roof coating last?
Lifespan depends on the coating type and thickness applied. We'll explain manufacturer details for the system we recommend. [ADD COATING WARRANTY DETAILS]
