As a result of these failures, most manufacturer's have changed the formula of the asphalt and stabilizers used in the shingle manufacture. They have not changed the fiber glass mat, which is still the backbone of the shingle. Only time will tell how these new shingles perform in the future.
However, one major manufacturer, CertainTeed, had no problems with splitting and cracking of shingles, due to their manufacturing standards. They developed their own fiber glass mats, and together with the correct amounts of asphalt and stabilizers, they confidently produced the finest shingle on the market today. They also provide the home owner with SureStart Protection . Simply put, if a manufacturing defect is discovered during the SureStart Protection period, CertainTeed will provide reimbursement of 100% of the cost of shingles and labor required to repair, or replace the defective product. The SureStart Protection period varies (from the first 5 to 10 years) depending on the shingle selected. After expiration of SureStart Protection, the homeowner is still covered by the remainder of the guarantee period of the shingle selected, (guarantee periods vary from 25 years to lifetime).
We cannot stress enough the importance of selecting a shingle that meets or exceeds the ASTM Standard Codes for Class A Fire Resistance, UL Wind Resistance, and High Tear Strength Resistance. These standards are available from all roofing manufacturer's and should be checked thoroughly before you decide on the shingle you will have installed on your house. All CertainTeed shingles, meet or exceed, all of the ASTM Standard Codes.
