What are typical problems with shingle roofs in south Florida? The number one problem is that they don’t last very long! InterNACHI gives 3-tab Asphalt Shingles 10 to 12 years and architectural or dimensional Asphalt Shingles 15 to 20 years. There are many factors that can affect their life, from the manufacturer, to how well they were installed, to which way the roof faces, overhanging trees and even the color of the shingles. If you are willing to spend money on repairs you can often extend the life of the roof as often the are parts of the roof where the shingles deteriorate quicker.
If you are not sure of the difference between the two types of shingles, have a look at the pictures below. 3 tab shingles lay flat whereas architectural shingles are thicker and you can see the different layers, hence the term dimensional shingles.
You can see several of the 3 tab shingles are missing. This is not uncommon on an older roof. You can have individual shingles or sections of shingles replaced if the rest of the roof is in good condition.
Here you can see shingles that are well and truly worn out.
If there are a number of shingles starting to lift this can be a sign that the roof is getting old.
Sometimes a roof may look okay but still be leaking.
The best way to see if a roof is leaking is to look in the attic.
