Fire or hot chimney flue damage to vinyl siding:
Obvious & less-obvious fire damage to vinyl on buildings. Aside from actually burned siding (shown in this article) vinyl siding more distant from an actual fire or from an improperly-installed chimney or flue may be buckled, rippled, bent, deformed, loose, or un-clipped. This article joins others in this series to help sort out different types and causes of buckled, rippled, bent or loose vinyl siding on buildings.
This article series discusses all of the known causes of buckled, loose, cracked or otherwise damaged vinyl siding. Rippled or loose vinyl siding may be more than just a cosmetic worry, and may indicate structural defects, building movement, leaks, or even heat or fire hazards.

Further Investigation of Rippled or Deformed Vinyl Siding Points to Reflected Heat vs Actual Fire Damage

As a contrasting example to vinyl siding damaged by reflected or transmitted heat alone, our photograph at left illustrates vinyl siding that was damaged in a Poughkeepsie NY house fire.
Watch out: for heating equipment installers who may run a metal vent through a vinyl-clad wall such as the installation shown at left Vent materials that get hot may risk a fire, or at least risk damaging the siding.

To understand with confidence why the siding at above right shows that rippled, bending effect, we recommended investigation
- into the condition of the fireplace insert installed in the building, from beneath, from the building interior,
- and ultimately by removing siding and sheathing to investigate the chimney chase cavity around the fireplace and chimney, looking for safety hazards, heat leaks, or fire risks as well as for evidence of other leaks or spills that might have caused this siding pattern
- Watch out: heat leaks around a fireplace insert could be a serious building fire or gas hazard
- Readers, especially Mike in Michigan, offered the best explanation for this particular case of rippled vinyl siding: damage caused by a combination of heat (from sunlight) reflected onto the siding from an adjacent window, and dead air space in the insider corner formed by the building wall and fireplace chase.
