Bloomington Metal Roof Coating FAQ

It usually is when the panels and framing are sound and the trouble is leaking fasteners, open seams, worn paint, or surface rust. Coating seals those weak points without tearing off the roof or interrupting the business below. It is not worth it over panels rusted through in many places or over saturated insulation.

Yes, if the rust is on the surface and the steel is still solid. Mill buildings often carry stone dust and heavy rust at laps, so we pressure-wash thoroughly, remove loose scale, prime bare steel, and replace perforated panels. Then seams and fasteners are sealed before the coating goes on.

Many coating systems often last 10 to 20 years. The actual life depends on the coating chemistry, how thick it was applied, the quality of cleaning and priming, and whether water drains off quickly. Hail, foot traffic around units, and skipped inspections shorten it; a timely recoat extends it.

Coating fits when the plant's metal roof is structurally sound and leaks come from fasteners, seams, and flashings. It keeps the roof deck closed, which matters over controlled production areas. Replacement fits when panels are perforated widely or the structure is failing. A moisture and panel survey shows which path applies.

Start with cleaning: pressure washing removes dirt and chalking, and hand or power tools remove loose rust. Bare and rusted steel then gets a rust-inhibitive primer that matches the coating system. Panels with holes are replaced. Proper rust treatment keeps the coating well bonded and stops corrosion from creeping under it.

Restoration includes cleaning, rust treatment, replacing failed fasteners, sealing seams and laps with reinforced mastic, repairing curb and edge flashings, and applying a full coating system. The existing roof stays in place, so there is no tear-off debris and the building keeps operating during the work.

It depends on the roof. Acrylic suits sloped metal roofs that shed water quickly. Silicone suits low-slope areas that hold water and gets strong UV resistance. Urethane base coats add toughness where hail or foot traffic is heavy. We match the system to slope, drainage, and the existing finish after an inspection.

Longevity comes more from thickness and preparation than from brand. Silicone and urethane systems applied at higher dry film thickness often last longest, and some can be recoated later to extend life again. Poor cleaning or skipped primer shortens any coating, so prep and measured thickness matter as much as the product.

Silicone is applied to a specified dry film thickness, which many systems reach in one or two coats. Seams, fasteners, and penetrations are reinforced first. We check wet film thickness with a gauge as we go so ribs, laps, and areas around rooftop units all receive the full amount.

Lifespans of 10 to 20 years are common for silicone coatings, depending on applied thickness, roof preparation, ponding, and roof traffic. Dirt buildup reduces reflectivity but not watertightness. Periodic cleaning, repair of punctures, and a silicone recoat at the end of its service life extend it.

Flatter roofs where water sits after rain suit silicone, which resists UV well. Acrylic fits sloped metal roofs with fast drainage and usually costs less per gallon. Acrylic is easier to recoat with other materials, while silicone generally needs silicone over it later. Slope and drainage usually make the choice.

Yes, when it goes over a clean, primed, dry surface with seams and fasteners reinforced. Silicone stays flexible and resists standing water and UV, which suits low-slope sections. It does not fix structural problems or wet insulation, so those are repaired before coating.

Lifespans of 10 to 15 years are common for acrylic coatings, depending on film thickness, slope, drainage, and surface preparation. Steeper roofs that shed water give acrylic its longest life. Ponding areas, debris, and foot traffic shorten it, and a recoat at the right time extends it.

Acrylic bonds to clean, primed steel and flexes with the expansion and contraction metal panels go through between summer and winter. It reflects sunlight and stays bright. It performs best on sloped roofs; low spots that hold water need correcting or a different coating in those areas.

Two or more coats are usual for acrylic, applied to reach the specified dry film thickness, often in different colors to confirm coverage. Each coat must dry before the next. Bloomington humidity and temperature affect drying time, so the schedule allows for weather between coats.

It can, on sloped metal sections that drain well. Mill roofs need thorough cleaning first, because stone dust weakens adhesion. Rusted laps and fasteners get primer and reinforcement. Flatter areas where water sits are better suited to silicone, so some mill roofs use both.

Twenty years or more is common for a spray foam roof when the protective top coating is renewed on schedule. The foam is protected from UV by that coating, so keeping it intact is the key. Hail punctures and foot-traffic damage are repaired quickly to keep water out of the foam.

Recoating is due when the top coating has worn thin, which we check by measuring its thickness and looking for exposed foam. We clean the roof, repair damaged spots, and apply a new coating over the foam. Recoating on time avoids removing the foam later.

Pros: a continuous, insulating layer that seals around penetrations and can be built up to improve drainage. Cons: it needs dry, mild weather to apply, overspray must be controlled near intakes and parked cars, and the coating must be maintained. For a plant with many roof penetrations, the continuous layer is a strong advantage.

Spray foam is weather-sensitive during installation, needs trained applicators to reach even thickness, and depends on regular recoating. Birds and sharp objects can damage it. It is also harder to find a small leak once water gets under the coating. These are manageable with good installation and inspections.

Shingle coating typically falls within the coating range of about $2.50 to $4.00 per square foot, with final pricing after an inspection. Roof size, pitch, access, cleaning, shingle repairs, flashing work, and the number of coats change the price within that range.

Yes. Offices, churches, clinics, and small retail buildings in Bloomington often have shingled sections. A coating made for asphalt shingles can slow granule loss and seal small gaps when the shingles are still flat and attached. Damaged shingles and flashings are fixed before the coating goes on.

Coating fits shingles that are still flat, attached, and mostly intact. Reshingling fits roofs with widespread curling, cracking, missing shingles, or a soft deck. We inspect the shingles and the deck before recommending either.

On a sound roof, coating keeps the building in service with little disruption; on a failing one, reshingling avoids coating over problems that will keep leaking.

Use a coating the manufacturer approves for asphalt shingles, commonly an acrylic or silicone formulated to let shingles breathe and to bond to granules. The shingles must be clean and dry, with loose ones fastened or replaced. Coatings made only for metal or flat membranes should not go on shingles.

Metal roof coating typically costs about $2.50 to $4.00 per square foot, and the final price is set after an inspection. Roof size, rust treatment, seams and fasteners to seal, panel replacement, access, and the coating system chosen change the price.

Usually. Coating typically runs about $2.50 to $4.00 per square foot, while replacement typically runs about $5 to $8 per square foot, both set after an inspection. Coating skips tear-off and new panels, but only makes sense when the existing roof is sound.

Water under loose fasteners and in seam laps freezes, expands, and opens the joint further each cycle. Over a winter that can turn a small gap into a leak. Sealing fastener heads and laps with coating and reinforcement closes those entry points before cold weather sets in.

Melting snow keeps water on the roof for days, and ice in gutters and at eaves backs water up against laps and fasteners. Small openings then leak. Sealed seams and fasteners and clear gutters before winter cut these leaks. We also check eave trim and ridge closures, where meltwater often works in.

Hail can dent panels and crack or puncture thinner coatings. After a hailstorm we check for exposed metal, cracked coating, and damaged fasteners, then clean and recoat damaged areas. A urethane base or thicker coating can add impact resistance on buildings that see repeated hail.

The Monroe County Building Department inspects and enforces adopted Indiana building codes throughout Monroe County. Indiana's code for commercial buildings is part of 675 IAC 13, adopted by the Fire Prevention and Building Safety Commission. We confirm permit needs for each roof project with the local office before work starts.

Indiana requires state building plan review for Class 1 structures, which include most commercial buildings. Whether a roof coating project needs a filing depends on its scope, so we check with the Indiana Department of Homeland Security and the local building office before starting.
