Is This Roof A Fit?
Acrylic needs a roof that drains and weather that stays dry while it cures. These four cases show where it fits.
If Your Roof
Covers A Church Or Office That Faces The Street
A crisp white finish that resists dirt pickup keeps the roof looking clean from the sidewalk.

If Your Roof
Holds Water Behind Rooftop Units For A Day
Acrylic softens where water sits, so the low pockets need a silicone system instead.

If Your Roof
Has Holes Through The Steel In Several Panels
Those sheets need replacing, and only then does any coating go over the rest of the roof.

Problems Acrylic Coating Takes Care Of
On a pitched metal roof the trouble sits at the overlaps and fasteners. These rows trace each one back to its cause.
Drips Under A Side Lap After Wind-Driven Rain
Likely Cause
Wind and capillary action pull water into the gap where two sheets meet at the rib.
What We Do
Seal the side lap with mastic or seam tape and run fabric across it in the base coat.
Faded, Chalky Paint On The South Slope
Likely Cause
Years of sun break down the factory finish, leaving chalk that blocks new coating from gripping.
What We Do
Wash with a maker-approved cleaner, run a test patch, then prime where the product sheet says.
Rust Freckles Along The Panel Ribs
Likely Cause
Dew collects on bare steel where the paint has worn thin at the rib tops.
What We Do
Brush off loose rust, prime the rib tops, and cover them with base and finish coats.
Wet Spots Below The Ridge Cap
Likely Cause
Foam closures under the cap break down and let blown rain past the cap screws.
What We Do
Swap the closures, tighten and seal the cap screws, and coat the cap edges into the panels.
Commercial Roof Coating Options for Bardstown
Acrylic systems differ in finish color and in what goes under them. These are the combinations used on pitched metal.
White Acrylic Finish
A bright white top coat reflects the most sunlight and shows dirt least. Its rated values are listed in the Cool Roof Rating Council directory.
Acrylic Over Rust Primer
Painted steel with red rust at the laps gets a rust-inhibiting primer first, then two acrylic coats over the whole roof.
Light Color To Match The Street
Roofs where looks matter can take a light gray or tan acrylic finish in place of bright white, still over primed panels.
Benefits of Coating Your Roof
Acrylic fits more pitched roofs than flat ones. These benefits come from that match between roof and coating.
Stays Bright And Clean
Water-based acrylic resists dirt pickup better than silicone, so a white finish on a church, office, or storefront roof keeps its look for longer. A brighter roof also bounces back more sunlight on summer afternoons.
Easy Recoats Later
Acrylic bonds to many coatings, so when the finish wears thin, a cleaned roof takes a new coat without stripping the old one.
Low Odor During Work
Water-based product keeps fumes low near open doors and office windows under the eaves while the coats go on.
Laps Bridged As One Piece
Fabric in the base coat lets each side lap and end lap move with the panels instead of splitting apart.
Planning Spring Or Fall Roof Work?
Acrylic needs dry afternoons and evenings above the maker minimum. Book early and the job can land in a dry stretch.
Steps To An Acrylic Coated Roof
Acrylic cures by drying, so weather sets the pace. This is the sequence we run on a pitched metal roof.
- Step 1:
Inspect Your Roof
We check the pitch and how quickly each slope drains, then walk the side laps, end laps, ridge caps, and screw rows. A test patch on the old paint confirms adhesion.
- Step 2:
Watch The Forecast
Dry afternoons with evenings above the product minimum are picked for each coat, since dew on fresh acrylic can wash film off the panels.
- Step 3:
Clean And Treat Rust
Panels are washed, chalk is removed with an approved cleaner, and rust at laps and rib tops is brushed and primed.
- Step 4:
Seal Every Overlap
Side laps, end laps, ridge caps, and pipe boots get mastic or seam tape with reinforcing fabric pressed into wet base coat.
- Step 5:
Roll Or Spray Two Coats
Base and finish coats go on at the film thickness on the product sheet, slope by slope, with each slope dry before the next coat starts.
Services For Other Roof Conditions
If acrylic is the wrong match, one of these usually fits the roof better.
Metal Roof Coating
Full metal restorations start with rust grading and fastener work before the finish is chosen.

Silicone Roof Coating
Low-slope roofs with puddles behind units need silicone, which holds up where acrylic softens.

Spray Foam Roofing
Shops that drip condensation or cost a lot to heat add foam under a protective top coat.

Why Do Metal Roofs Leak At Panel Laps?
Water pulled into gaps
Two sheets meet at every lap, and wind plus capillary action pull water into the gap. Side laps run up the slope at the ribs; end laps cross it where panels overlap. End laps are worse, since water runs straight in and the tape inside dries out. Each lap is cleaned, sealed, and bridged with fabric.
When Does Acrylic Make Sense On A Metal Roof?
When it drains fast
Acrylic fits metal roofs with enough pitch that rain runs off within hours, such as gable shops, equipment buildings, and church or office roofs that drain quickly. In Nelson County, spring and fall jobs need dry afternoons and evenings above the product minimum, because dew on fresh acrylic can wash film off the panels.
Does A White Coating Keep A Metal Building Cooler?
Cooler roof surface
A white finish reflects more sunlight than faded paint or dull Galvalume, which lowers the roof surface temperature on summer afternoons. The Cool Roof Rating Council lists solar reflectance and thermal emittance for rated products, new and weathered. Compare a summer of utility bills before and after, since any change inside shows up there. Washing helps, because dirt lowers reflectance.
How Many Coats Go On A Pitched Metal Roof?
Usually base plus finish
Most acrylic systems call for a base coat and a finish coat, with primer under them where rust or the old paint requires it. The product sheet sets the dry film thickness, and crews check it with a wet film gauge as they work. Laps and screws get extra material in the base coat.
Can Acrylic Be Tinted To Match Nearby Buildings?
Light colors, yes
Light gray, tan, and other pale colors are available in most acrylic lines. Darker colors absorb more heat and reflect less sunlight, so they give up some of the cooling gain a white roof offers. Inside the Bardstown historic district, bring color samples to the preservation office before ordering.
