A Three tab shingle is an industry term for the entry level composition shingle also known as a “strip” shingle. This entry level product is not laminated like dimensional shingles.  The product has a product warranty from 20-25 years. This product has a typical wind warranty of 60-70 mph. It is common practice to cut these shingles between the three tab’s of the shingles to be utilized at the hips and ridges on your roof. We recommend the utilization of a pre-manufactured hip/ridge shingle that has life expectancy and wind performance comparable to the field shingle. Your roof is only as good as its weakest link.
