In Fact, we find nigh edifice owners aren't even aware that you could install another metallic roof on top of your existing metal roof, (metallic over metal retrofit) , or that you could install a TPO/PVC flat roofing membrane overtop of your existing metallic roof, (Metallic roof retrofit).

Moving frontward, information technology'due south worth noting that metal roof coatings are easier to compare to the TPO/PVC membrane over metallic option than the metal over metal roof overlay.

3 Major Reasons Why A Metal Roof Coating May Not Exist The Correct Solution For Your Building

ane. Awarding Issues- Weather condition Plays A Huge Role In The Successful Installation And Performance Of Metal Roof Coatings Merely Metal Roof Overlay Systems Can Be Installed Year Round

The showtime major deviation between a metal roof coatings and a metal roof overlay system is that the roof coating can only be installed in the correct temperatures. Some metal roof coatings can exist installed in temperatures as low every bit 40 degrees and rising whereas other coatings must have 60 to 65 degrees and rise temps. These temperature restrictions reduce the installation window of metal roof coatings in many climates around the country.

Information technology may or may not exist the right time for your business or your budget to tackle metal roof repairs when the temps and weather conditions are right simply metal roof coatings offer little flexibility when it comes to temperatures.

In addition to temperature restrictions, other weather condition and environmental weather condition must exist considered like Humidity, dew signal temperature, frost, dew, and condensation.

In order for the metal roof coating to adhere correctly to your building's metallic roof, the surface must be clean, dry out, and gratis of loose debris or any other contaminants.

Metal roof coatings that require multiple coats to exist applied accept varying dry times between applications that range from 16-24 hours out to 3-5 days again depending on air temps, surface temps, humidity levels etc.

The ability for a metallic roof coating to keep your building dry out and its long term performance is very much tied to the conditions it is installed in. Less than platonic environmental conditions = less than platonic overall operation of the coating.

None of these conditions, temperature or environmental factors come into play with metal roof overlay systems. The TPO/ PVC membrane tin be installed over an existing metal roof in a wide range of temperatures especially when existence installed "mechanically fastened" as there is no glue, sealants, or annihilation that needs "dry out time". And the metal over metal roof overlay can too be installed in cold temps with no thought about humidity, dew point, or adhesion problems.

The main idea backside most metallic roof coatings is that as multiple layers of coating are applied, you are " building a waterproof membrane right on top of the existing metallic roof. The problem is that edifice the water proof membrane on the existing metal needs to be done during ideal temperatures and conditions atmospheric condition that seldom occur.

A metallic roof overlay system, especially the TPO/PVC covering membrane over metallic is not existence "built or practical" in the field simply rather installed. The membrane is already created, all that needs to happen is for it to be installed correctly.

There is a major divergence between a metal roof coating being used to create a membrane vs. having a membrane or new metal panel already fabricated and having information technology installed over the existing metallic roof.

Metal is a super durable and long lasting material, after all that's why it's made it into roofing. And metal covering rarely leaks just out in the middle of the roof somewhere for no reason. Leaks are almost ever centered around Pipes, seams in the metal sheets, behind HVAC units, or on the screws or trims.

So it's reasonable to want special care given to the well-nigh leak prone areas of the roof, but metal roof coatings come upwards short in these critical areas. All you get around the pipes and behind the units is more coating which in many cases causes h2o to become trapped and pond backside the pipes or units and makes the leaks fifty-fifty worse.

Metal roof overlay systems come standard with all new flashings around pipes, HVAC units, and they recover old leaking trims, not merely paint them white.
