Two Finishes, Two Primers
Fresh factory paint can be too slick for some coatings, while old paint is chalky. Tests on both decide the primer for each.

Tying New Replacement Panels And Old Steel Into One Coated Roof
DuBois metal roof coating often follows a few panel swaps; we test the old and new finishes, check the joints between them, and coat both as one roof.
FocusOld And New Panels
- New Panels Lapped In Tight
- Each Finish Tested
- Screws Checked Across The Roof
- One System Over Both
DuBois Metal Roof Coating After Panel Replacement
Storm damage or rust often leaves a roof with a handful of new panels among old ones, and DuBois metal roof coating has to bond to both. Factory finishes on new panels differ from aged, chalky paint, so each gets its own cleaning and adhesion check.
The laps where new meets old get extra attention before coating. Owners often call after an insurance repair has swapped the worst panels. The rest of the roof still carries the original screws and laps, and that is where the coating plan does most of its work.
- Adhesion tested on old and new finishes
- Joints between new and old panels sealed
- Hidden moisture checked beyond the swapped panels
Metal Roof Coating Issues on Patched DuBois Roofs
Roofs with replaced panels share four issues that shape the coating plan.
Laps Where New Meets Old
Panel profiles from different makers rarely nest perfectly. Those laps get sealant, fabric, and a closer look.
Screws Beyond The Swapped Panels
Replacing damaged panels fixes one area. The screw rows across the rest of the roof still need checking.
Water That Reached The Insulation
Damage that justified new panels often let water in first, so insulation nearby is probed for moisture.
Dents Left From The Same Storm
Panels near the swapped ones often carry smaller dents and cracked washers. Each one is checked before coating.
Gutters Bent By Ice And Debris
Storms that damage panels often bend the gutters too, and those get rehung so water leaves the roof.
Benefits of Coating Your Roof
A roof with mixed panels finishes as one surface once it is coated.
One Surface Over Old And New Steel
A roof patched with new panels looks and ages unevenly, and the joints between old and new are where leaks start. A single coating system over both, with each finish primed correctly and every new-to-old lap reinforced, turns the patchwork back into one roof.
Joints Reinforced Where Profiles Differ
Fabric and sealant close the gaps where new panels do not quite match the old ribs.
An Even Look Across The Roof
Bright new panels and faded old ones end up the same color under the topcoat.
Metal Roof Coating for DuBois Businesses
Shops and warehouses keep working while the roof is coated in sections.
Commercial Roof Coating Options for DuBois
Mixed roofs here usually take one of these builds after the panel work.
Full Field
Primer Matched To Each Finish
Old and new panels each get the primer their test calls for, then one coating covers both. Every lap where profiles meet gets fabric and sealant.
Low Bays
Silicone Where Water Lingers
Low sections around the new panels take silicone if water sits there after rain. Low spots by the new panels are checked for a sagging purlin.
Insulation Need
Foam Over The Whole Roof
Buildings that also need insulation can take foam over old and new panels alike. Old and new panels both get fastened tight before spraying.
Mixed Buildings
Shingle Sections Hit By The Storm
Shingle faces damaged in the same storm get tabs and flashing repaired first, then coated only where the maker allows. Storm-loosened flashing is reset before any coating.

Metal Roof Coating Steps for DuBois Roofs
Four steps, with the new-to-old joints handled before coating.
Inspect Your Roof
We test adhesion on old and new finishes, check the laps between them, walk every screw row, and probe insulation near the damage.
Seal New-To-Old Joints
Laps where profiles meet get sealant and fabric, loose screws are replaced, and wet insulation is removed.
Clean And Prime Each Finish
Old paint is washed and its rust primed, while new panels get the cleaning or primer their test calls for.
Coat Both As One Roof
Base and top coats go on across old and new panels at full thickness, with extra build at the joints.
Recheck The New-To-Old Laps
After the first heavy rain, the joints between old and new panels get another look for any sign of water.

Mixed Panels
Can a DuBois Commercial Roof Be Coated After Only the Damaged Panels Are Replaced?
Yes, when the remaining panels and the new ones both accept the coating system. We check the joints between old and new and set up preparation for each finish. Swapping the visibly damaged panels still leaves the screws, seams, and hidden moisture elsewhere to check.
Do New Panels Need to Weather Before Coating?
Not always. Some new finishes need a cleaner or primer to give the coating something to grip, and the adhesion test tells us which, so the roof does not have to sit for a season.
Cost
How Is DuBois Metal Roof Coating Cost Figured on a Patched Roof?
Roof area sets the base, with coating running about $2.50 to $4.00 per square foot. Separate primers for two finishes, extra work at new-to-old laps, and screw replacement move a roof within that range.
Is Panel Replacement Priced Separately From Coating?
Yes. Panel work and coating are listed as separate lines, so you can see what each part of the job costs.
Should the Coating Wait Until Storm Repairs Settle?
Coating can follow soon after the panel work. Fresh sealant at the new laps needs its cure time, and the adhesion tests confirm when the new panels are ready.
Finding Help
