Roof Coating

A roof coating is a liquid-applied layer that cures into a seamless, waterproof skin over an existing roof. Done on the right roof at the right time, it can add years of life without a tear-off. Done on the wrong roof, it hides a problem that keeps getting worse underneath.

Which roofs can be coated

Coatings are made for low-slope roofs and metal roofs: aging EPDM, TPO, modified bitumen, built-up roofs and metal panels with rust starting at the fasteners and seams. They are not a fix for an asphalt shingle roof. The key requirement is that the roof underneath is basically sound and dry. A coating seals the surface, but it cannot dry out wet insulation or stiffen soft decking.

Silicone, acrylic and other coatings

Silicone coatings handle standing water well, which makes them a common choice for flat roofs that pond in spots. Acrylic coatings are economical and reflective but do not tolerate standing water as well, so they suit roofs that drain cleanly, including many metal roofs. Other elastomeric products exist for specific substrates. Most coatings are white, which reflects summer sun and keeps the roof and the space below cooler.

How a coating is applied

  • Inspect the roof and check for wet areas, which are cut out and replaced.
  • Power wash and clean the surface so the coating can bond.
  • Repair open seams, blisters, punctures and loose flashing.
  • Reinforce seams, fasteners and penetrations with fabric or seam sealer.
  • Prime where the substrate needs it.
  • Apply the coating in one or more coats to the specified thickness.

Coatings and drainage

A coating does not change the slope of the roof. If water ponds because the framing has sagged or a drain sits high, that should be corrected or accounted for in the coating choice. Edges and the gutters or scuppers they drain into should be cleaned and checked during the job, since a coated roof still depends on getting water off quickly.

We have used NJ Gutters for all of our gutter work. It does take some time to get on their busy schedule, but it is definitely worth the wait. They are the best. Whenever we ask trusted contractors (both our builder and roofer) for gutter work recommendations, they always say NJ Gutters. They are trusted by both excellent contractors and homeowners. NJ Gutters most recently installed gutter caps and we were a little hesitant to install them because we were worried about how they would look, but they are hardly noticeable and the result is great. Highly recommend NJ Gutters for all of your gutter work!

After 20 years, my gutters and downspouts were in dire need for repair. I did research sent out bids got several companies. NJ Gutter was the most responsive and price competitive of the four companies who responded. They performed a thorough site visit including getting access to my roof and inspecting all of the areas. They didn’t just suggest swapping in new materials but improving the “pitch” of some of my gutters, leaf guards and the size of the gutters/down spouts. The “repair” team was fantastic. They were courteous, thorough, diligent and maintained a clean work environment. They also pointed out some additional “damaged wood” that needed replacing. They gutters/downspouts look great. I would highly recommend using them for any gutter issues you might have.

Dealing with contractors is not one of my favorite things to do, but I felt compelled to write a review about my recent experience with NJ Gutter. Jimmy came out and handled everything like a true professional (don't see that these days too often). He inspected my home and made some awesome recommendations. I told him I was having the roof and siding done so he supplied color samples so I can have the trim color match the gutter color which came out great. Then he suggested we use "stone coated gutter cap" that looks like roof shingles and blends right into our new roof. He also corrected a water runoff problem I had on heavy downpour rains by suggesting a larger gutter & downspouts which again worked out great. The job was completed on time and as quoted with no nonsense. If it wasn't for his attention to detail and vast experience who knows what I would have wound up. After all who thought gutters could be this technically advanced? Thanks NJ Gutter Team! They did such a great job....I came back fr more. NJ Gutter just installed gutters and leaders on another home for me. And of course, another GREAT Job!

Process

How long does a roof coating last?

It depends on the product, thickness and conditions. Many coatings are designed to be recoated after a number of years rather than replaced, which keeps renewing the roof surface.

Can a coating stop a leak?

Only if the leak is fixed first. The repair work before coating, at seams, flashings and punctures, is what stops the leak. The coating then protects the whole surface.

Can you coat a shingle roof?

We do not recommend it. Shingle roofs shed water by overlapping, and coating them can trap moisture. A worn shingle roof needs repair or replacement.

Is coating cheaper than replacing a flat roof?

Usually, when the roof qualifies, because there is no tear-off or new insulation. If large areas are wet, replacement is the better value. Compare with the flat roof cost guide.

Warranty

What warranty does New Jersey Gutter offer?

New Jersey Gutter backs its work with a workmanship warranty. It covers how the job was done: seams, hangers, pitch and fastening. Gutters, guards and other products also carry their manufacturer's material warranty. Your length and terms are written on your estimate and invoice.
