Hail Impact Resistant Shingles

Who Is UL & What Is A Class 3 And 4 Impact Resistant Roof?

Impact (hail) testing class sizes for impact resistant shingles

The Owens Corning Duration Storm Impact Resistant Shingles are a Class 4 shingle that can potentially save you money on your homeowners insurance. Class 4 materials offer some of the best long-term roof protection available to homeowners. Excel Roofing recommends the Owens Corning Duration Storm, a UL 2218 Class 4 asphalt shingle. It is one of the highest-quality shingles on the market.

Underwriters Laboratories (UL) 2218 classifies the resistance of roofing products to impact damage. In the test, steel balls are dropped on roof shingle samples and the shingles are examined for damage. Products that receive a Class 4 rating from UL are the most resistant to hail damage. Some property insurance companies will give a premium discount on homeowner insurance for using impact resistant-shingles.

T-LOCK Shingles Should Be Replaced

Back in 1930 when they were introduced, T-Lock shingles were the latest and greatest in roofing technology.  They were easy to install and could withstand high winds and storms.  The T-Lock shingle was ideal for Colorado’s always-changing and often-threatening weather.  The heavier and thicker asphalt shingle found many home along the Front Range and across our state.

T-Lock shingle example


Not too much tech from the 30s is still in use today, including the T-Lock shingle.  Their manufacture was halted in 2005.  Even though they were rated to withstand winds up to 130 mph, their “wing” design actually acted like a sail and would rip off the roof during much slower wind speeds.


Also, as asphalt became more expensive, fillers were used instead.  These fillers would become very brittle over time. Their woven design and installation doesn’t offer solid protection against hail either.  The weaves can create pockets and gaps between shingles that can be easily damaged by hail.


Basically, the T-Lock shingle lived long past its prime.


Many insurance companies won’t insure homes with a T-Lock roof.  A new policy taken out on a home with T-Lock shingles will most likely require a roof replacement.


So if you are buying or selling a home with a T-Lock roof, it would be a good idea to call your insurance agent. If your T-Lock roof is damaged, it just simply can’t be repaired.  No one makes them anymore.  And your insurance company just may cover some of the costs to replace a T-Lock roof.  They would prefer your home to have a newer roof that will better withstand the elements. Insurance companies just don’t like them, plain and simple.


They want to push the financial responsibility onto the homeowner.  T-Lock roofs have depreciated value.  They are tough to sell without being replaced.  And it really is only a matter of time before they fail.


If you have a T-Lock roof and have any question, please contact Excel Roofing!  We will be happy to assist you in any way we can and will even inspect your roof free of charge.

Love Chris, had my best interest in mind during the entire roof replacement process. He was able to rush the job for us given that we were nearing the closing date of the sale of the house.
