What Does Melted Siding Look Like?

This one’s easy enough, since if you’ve ever seen melted plastic, you’ll know what melted siding looks like. Although vinyl siding is a blend of materials created for added durability and aesthetics, it is still plastic at its core, and thus behaves much like plastic under heat stress. If your siding is bulging irregularly, bubbling, or getting quite wavy and runny-looking in an isolated spot, the odds are very good that what you’re looking at is a melted section of siding.

Is Melted Vinyl Siding Common?

Not at all, actually. Barring home fires or a fireworks display gone wrong there are only a very few things that can cause siding to melt. And even these require a lot of things to go right (or horribly wrong, we guess) in order for the issue to manifest.

This is because even the lowest quality vinyl siding has to hit temperatures of over 150 degrees to begin melting. Which is of course quite hot! The only times this ever really happens is when there are certain window types nearby—ones that are specifically built to reflect sunlight and heat. These types of windows include:

  • Double and triple pane windows
  • Low-E glass or treated windows
  • Windows installed with a reflective coating

This issue is even less likely when your siding is of a higher quality or grade, as top-end vinyl siding is treated and constructed specifically to get rid of this potential weakness altogether. If you’ve got top-tier home siding and you’ve still got melting going on then something is seriously wrong. Either with the siding product itself, or with your windows.

Do I Need Siding Replacement if I Have Melted Siding?

Unfortunately you do need a replacement in this case. But the good news is that your siding replacement doesn’t need to be a full replacement. Sectional siding replacement is another of the great advantages of vinyl siding, meaning the service in the hands of a pro can take as little as a handful of hours, and can actually be quite friendly cost wise.

You will want to find out what caused the issue in the first place, of course. If the culprit is a nearby window then a solution will need to be found first, though there are many ways to go about this (block the rays with shrubs or trees, install a screen on the window, install an awning, etc).
