Compare 30 year shingles: 3-tab vs. Dimensional.
Asked Apr 13, 2011, 10:19 AM
I manage apartments. We have 40+ buildings that were previously done with 25 year 3-tab shingles.
We want to start using 30-year shingles when we have a roof (or one side below the ridge vent) that needs replaced...
I'm finding that the 30-year 3-tab shingles are about $2 per square more than the dimensionals, but my roofer is telling me that the dimensionals are better: Thicker, seal better, less resistant to wind, etc.
I'm leaning toward the 30-year 3-tab shingles since they'll more closely match the roofs that we have now, but if they are truly inferior to the 30-year Demensionals, then I'll go with dimensional.
Can any of you give me an opinion based on your experience?
