Just like any other industry, materials in the roofing industry are constantly evolving and improving. What was once a premier roofing material may not even be produced anymore. One once popular material that fits into this category is the T-Lock shingle, let’s take a look at the T-Lock shingle, why it was so popular, what happened to the T-Lock and what you should do if this material is on your home.

What is a T-Lock Shingle?

Like the name implies, T-Locks were shaped like large letter Ts, this designed allowed the shingles to lock together to form good protection against wind and other adverse weather conditions. You can take a look out at your roof and should be able to see this distinct pattern if your roof has T-Locks. This design made it popular in windy areas and the shingle was in mass production from around the 1930s to 1980s.

What Happened to the T-Lock Shingle?

Innovation happened. Material manufacturers were able to produce new and better materials to stand up against wind and other severe weather that made the T-Lock shingle obsolete. There were also material manufacturers who tried to skimp on material costs and the product’s quality suffered in the end.

What Do I Do If I have a T-Lock Roof?

If the roof is in good condition you don’t really have to do anything. Unfortunately, because the material is outdated some homeowner’s insurance companies are increasing their premiums for T-Lock roofs or cancelling the policy altogether. The policy will differ depending on the individual home and insurance policy. It will not matter if the shingle came with a “lifetime” warranty by the manufacturer in the insurance company’s mind as this material is often labelled as a liability hazard.

If you’re curious as to the condition of your T-Lock roof you should have a certified roofing consultant out to examine the quality of the work and the material. In many windy areas roofing companies have dealt with this material and can help you make decisions on where to go to replace the material. If you are calling a roofing company make sure they are knowledgeable about T-Locks to help you figure out what to do next.
