As a Mount Joy metal roof coating contractor, we repair and coat long metal roofs on warehouses and storage buildings in sections around loading hours.
Mount Joy metal roof coating jobs often cover a long warehouse or storage roof with an older coating already on it. We test that coating first, since new film holds only as well as the layer under it. Sections are planned around dock doors and truck schedules.
Each section is repaired, washed, primed, and coated before the next one opens. Old gutters and eave laps usually show the worst wear, so those sections often go first.
Systems we use most here: Commercial Metal Roof Coating, Acrylic Roof Coating, Spray Foam Roofing
Warehouse roofs show trouble over aisles and docks. These are the signs we trace back to the roof. Most start at an eave or a lap.
Pieces of old white coating collect on racking and the floor.
The earlier coating has lost its grip on the metal and is peeling in sheets.
Loose film is scraped and washed off, adhesion is tested, and primer goes on before recoating.
Water runs down the wall above a loading door after rain.
A clogged or sagging gutter is overflowing back under the eave laps.
Gutters are cleared, refastened, or replaced, and the eave laps are sealed before coating.
Small drips land in a straight line down a long aisle.
A row of fasteners has loosened as the long panels expand and shrink each day.
Fasteners are tightened or upsized with new washers and the row is primed and coated.
Light shows where two panels meet partway up the slope.
End laps have separated as the roof moved over many seasons.
End laps are pulled tight, sealed, reinforced with fabric, and coated.
On a Mount Joy warehouse or storage building, a coating over a repaired roof brings these gains.
New coating goes over tested, primed metal instead of a peeling layer.
Sections are scheduled so trucks load and unload while the roof is coated.
Separated panel ends are tightened and sealed under one film.
A white topcoat reflects summer sun off long steel roofs over stock.
Repaired gutters and sealed eave laps stop overflow at dock walls.
Primer and coating keep rain off surface rust so it stops growing.
Later on, a wash and fresh topcoat renew the roof without new panels.
You get notes on what was repaired and coated in each section.
Long warehouse roofs in Mount Joy usually fit one of these four systems, picked after the old coating is tested.
Older acrylic that still grips after washing can take a new acrylic coat over a compatible primer.
Low-slope dock canopies and flat additions that hold water take silicone once outlets are clear.
Unheated storage turned into heated space can gain insulation from spray foam with a topcoat.
Warehouse offices with flat, flexible shingles can take an approved shingle coating; worn ones get replaced.
Peeling film means the grip underneath has failed. Call us and we will test how much of the roof needs stripping before a recoat.
Five steps, run one roof section at a time so the warehouse keeps shipping.
We walk the full length, test the old coating for grip in several spots, and mark loose fasteners, open end laps, and gutter damage.
Roof sections are matched to the dock doors and aisles below, and each one gets a start date that fits shipping.
Peeling coating is removed, fasteners are tightened or upsized, end laps are sealed, and gutters are repaired.
Each section is washed and dried, rust is brushed down, and a compatible primer goes on.
Base and top coats go on at the specified thickness, then work moves to the next section.

Millersville metal roof coatingOnly after the peeling is dealt with. We check how much film has separated and whether the layer still on the roof grips firmly. Loose acrylic is scraped and washed off.
New coating over a weak layer would peel along with it, so the surface has to be firm first.
Coating plans at about $2.50 to $4.00 per square foot of roof and replacement at about $5 to $8. Stripping old coating, end lap and gutter repairs, fastener work, coating type, and thickness all move a warehouse within that range.
The roof is split into sections that line up with dock doors and aisles. We agree on which sections run on which days, protect stock under active areas, and keep wash water and overspray clear of trucks.
Yes, storage and equipment buildings around Mount Joy get the same inspection and repair steps as larger warehouses. Smaller roofs are often finished in one working stretch.
Usually only under the section being washed and sprayed. We cover racking and floor areas nearby, and stock elsewhere in the warehouse stays put while that section is done. Racking under skylights or exhaust fans gets an extra cover.
Gutters with rust holes or sagging hangers are repaired or replaced before the eave laps are coated. A gutter that overflows sends water back under the laps, so it gets fixed as part of the roof work.
Send the roof size and where the leaks or peeling show. We inspect, repair, and coat one section at a time.
