Common Concerns with Vinyl Siding

Vinyl siding has become the colorful, affordable solution for many Canadian homeowners. However, that said most man-made things do eventually begin to degrade, and that’s equally true of this product.

It can for example warp and buckle due to temperature extremes, and come loose after violent winds and storms. Much of this can be detected during annual inspections, and plans put in place to do what’s necessary to restore it.

The Commonest Causes for Vinyl Siding Problems

The most common issues with vinyl siding we encounter, are the result of one of two underlying reasons. These root causes include:

  • Improper installation that prevents the material flexing, and responding to temperature variations.
  • Installed siding buffeted by summer heat, winter cold, storms, winds, and neglect by homeowners.

Siding should be able to move a quarter-to-a-half-inch horizontally either way, as a general rule of thumb to adapt to these stresses. If you have vinyl siding and you can’t do this, then we recommend you call in a contractor to make important adjustments.

Other Reasons Why Vinyl Siding May Distort

There are several other, fairly common reasons for vinyl siding distortion, although incorrect fixing may make it worse:


All buildings shift slightly, as temperatures and soil density vary between seasons. But older homes are more prone to this, as their foundations progressively settle. The wise homeowner takes these signs seriously as they may indicate deeper-seated problems.


However, the vinyl siding distortion may also be a warning of wood-eating insects attacking the battens holding the siding, or even the underlying structure of a timber home. These problems are most likely to affect the lowest few rows of siding.


Vinyl siding should repel moisture as it trickles down, or washes over during a rainstorm. Overlapping joints should prevent capillary action, but again only if the installation was properly done. Consult a siding expert as soon as you notice damp in your home.


Windows and doors are openings in siding runs, and therefore one of their weakest points. Always insist these have adequate flashing that works, to avoid future problems. If you notice caulk coming loose, or warped panels then it is time to take action.
