Mr. Roof/Able Roof Thunderguard is a joke.
Its an SBS shingle instead of fiberglass/asphalt like most shingles.
Here is the busted truth on this shingle.
Its supposedly a "lifetime" warranty shingle. But the catch is that after the first 10 years the homeowner has to call every year to re-new/continue the warranty. So if day 1 on year 11, you forget to continue the warranty--you will then have no warranty.
They dont manufacture their own shingles. They buy these private labeled from Malarky.
Bottom line: Mr. Roof is a joke (the original owner/now minority owner is an A-hole). Mr Roof started in Ann Arbor. Able Roof Co. from Columbus, Ohio bought 2/3 of Mr. Roof a couple of years ago. Able Roof bought the company to branch out the name all over the midwest. They went to Indy about the time of the hailstorms and did a lot of bad things. Then they went to Cincinatti...Have sold only a few jobs there in a year...They recently shut down Indy because of the financial losses incurred by offering a warranty that were forced to honor. Able Roof and Mr. Roof private label IKO(worst on the market) dimensional shingles and call them "roof guard".
Im not sure where you are located..But IMHO stay away from Mr. Roof and definitely IKO and Thunderguard.
If you want a real lifetime warranty, go with a GAF/Elk Lifetime shingle with Golden Pledge warranty or Certainteed Lifetime with similar package. The price will probably be the same, because Mr. Roof tries to get top dollar for the Thunderguard.
