Metal Roof Coating Short Hills, NJ
A Short Hills roofer can tell you whether a metal roof is a good coating candidate and apply the full system: cleaning, rust treatment, primer, seam sealing and topcoat, as long as the panels have not rusted through. Call (862) 424-5211 to reach a local roofer.
Coating a metal roof means adding a seamless, rubbery layer over the whole surface to seal it and protect the metal. By the time a metal roof is a coating candidate, the paint is usually chalky, rust has started at screw heads and seams and a few fasteners leak. What a coating cannot do is fix rust holes, rotted framing or panels that are loose, so those are repaired first.
Most metal roof coatings are acrylic or silicone. Acrylics are flexible, reflective and recoatable, and they suit sloped metal that sheds water quickly. Silicone stands up to ponding and sun, which is why it is popular on low slope metal.
The prep work matters more than the coating itself. Cleaning, rust treatment, fastener sealing and seam reinforcement all happen before the first coat. Rain or cold during curing can ruin a coating.
Metal Roof Coating is often paired with metal roof repair and roof coating, depending on the cause.

The metal roof coating process
Here is how a roofer usually coats a metal roof.
Inspect the roof
The roofer checks for rust-through, loose panels, rotten purlins and the condition of the fasteners and finish. An adhesion test shows whether the coating will stick to this roof.
Remove chalk
Chalk and dirt are washed off so the coating bonds to the metal. Everything has to be dry before primer goes on.
Prime the metal
Rusted areas are wire brushed and primed with a rust-inhibiting primer. Rust that has gone through is patched first.
Reinforce seams
Screws and laps are sealed and reinforced so the coating spans them without cracking. This step stops most active leaks.
Topcoat
Coats are sprayed or rolled on and checked with a wet film gauge. The roof is left to cure in dry weather.
What is included
What a metal roof coating includes

Metal Roof Restoration Short Hills, NJ
Restoring a metal roof means fixing what is broken, then coating the whole surface. Before coating, rusted panels are replaced, screws renewed and flashing repaired.
Many Short Hills owners choose restoration when the structure is solid but the surface is worn. It also skips tear-off and disposal of the old metal. Ask the roofer which repairs are needed before coating and how thick the coating will be.

Metal Roof Painting Short Hills, NJ
Metal roof painting is a lighter job than coating, aimed at restoring color and rust protection rather than sealing leaks. Paint is much thinner than an elastomeric coating, so it will not bridge open laps or seal leaking fasteners.
If a Short Hills roof is not leaking and only looks worn, paint may be all it needs. The surface still has to be cleaned of chalk and rust primed first, or the paint will peel. Leaking roofs need a coating, not just a fresh color.

Roofs in this climate
Winters here are long and cold, with snow on the roof for weeks at a time and plenty of nights below freezing. Heat escaping from the attic melts snow on the upper roof, and the water refreezes at the colder eaves, building ice dams that push water up under the shingles. Strong coastal storms push rain into every weak spot at the flashing and valleys. Most homeowners in Short Hills, NJ have the roof checked in the fall and again after the snow melts.

Metal Roof Coating FAQ
What type of coating works on a metal roof?
Most metal roofs are coated with acrylic or silicone. Acrylic is flexible, reflective and easy to recoat, and it suits sloped roofs that drain well, while silicone handles ponding water and sun but only bonds well to more silicone later. The right choice depends on drainage and how you plan to maintain the roof.
Is my metal roof a good candidate for coating?
The best candidates are structurally sound roofs with surface rust, faded paint and leaking fasteners or seams. Roofs with widespread rust-through, rotten purlins or loose panels should be repaired or replaced instead. An inspection with an adhesion test answers the question.
When will a coated metal roof need recoating?
The life of a coating depends mostly on its thickness and type. Recoating at the right time adds years without redoing the prep. Watch for thinning or chalking as signs a recoat is near.
Should I paint or coat my metal roof?
The difference is thickness and purpose: paint protects and colors, coating waterproofs. Leaky roofs need a coating, and dry roofs that only look worn can often be painted. Both need the same careful prep.
Can a roof coating fix metal roof leaks?
A coating system seals fastener heads, laps and seams, which is where most metal roof leaks begin. Holes, loose panels and structural damage are fixed before the coating goes on. Call (862) 424-5211 to have the roof checked.
