What fails first here
- 1Green algae & mildewThe most common complaint about white vinyl. Tampa’s damp climate (decay index 103.6) feeds it on the shady side and near the ground. A garden-hose wash with mild soap removes it.
- 2Chalking & slight yellowingUV slowly breaks down the surface of PVC, leaving a dull, chalky film. UV here ranks #4 of 25.
- 3Sagging in heatAbout 94 days a year top 90 °F; long rails and gates can sag or bow if posts are too far apart.
- 4Cracks from cold impactsRare here: only about 1 freeze–thaw days a year.

How long does a vinyl fence last in Tampa?
Our model puts a vinyl fence at 22–28 years in Tampa (national typical range 20–30 yrs). It never rots; what ends its life is UV chalking, brittleness in cold and impact damage.
How often should you clean a vinyl fence in Tampa?
Twice a year — in spring and fall. Tampa’s damp climate makes green algae on the shady side the most common complaint.
Vinyl or wood fence: which lasts longer in Tampa?
Our model gives a vinyl fence 22–28 years here and an untreated cedar fence 10–13 years. Vinyl needs washing instead of staining, and it does not rot at the posts.
Why does a white vinyl fence turn green in Tampa?
The green film is algae and mildew growing on dirt and pollen that sit on the surface, mostly on the shady side and near the ground. It does not damage PVC; a wash with water and mild soap (or a vinyl cleaner) removes it.
