T Lock Shingles: Why Denver Roofers No Longer
Use This Roofing Material.

Made popular in the 1930s and widely used on houses throughout the 1980s and 1990s, a T-lock shingle roof has a T-shaped design that enables the shingles to interlock. T-lock shingles were the best option for roofing due to their ability to withstand high winds. This is especially the case in areas such as Denver, Colorado Springs, and other surrounding communities where high winds are prevalent.

Primarily made of asphalt, a T-lock roof shingle is heavy and sturdy. When manufacturers gradually reduced the amount of asphalt used, the T-lock shingle became weaker. Instead, fillers were added as asphalt prices rose, causing the shingles to become thinner, more brittle, and less capable of withstanding the wrath of inclement weather.

T-Lock Shingles No Longer Used

When architectural shingles were introduced, the use of T-locks declined dramatically, to the point where it was no longer cost-effective to produce them. In fact, by the 2000s, manufacturing of T-lock shingles stopped entirely as alternatives rendered them obsolete. This made repairing T-lock shingles out of the question because replacement shingles were no longer available. Depending on where you live and the age of the roof, nearly every roof with T-locks will qualify for a new roof or roof replacement.

Many Insurance Companies Don’t Insure a T-Lock Shingle Roof

In addition, when a homeowner is looking to buy or sell his or her home, T-lock shingles are less likely to be insured by most insurance companies. It’s important to speak with your insurance agent to find out if the insurance company that writes your homeowner’s insurance coverage will cover hail damage and wind damage for T-lock shingles. Buyers are also less likely to purchase a home with a T-lock roof unless the seller gets the roof replaced. Buyers should find out if a home has a T-lock roof or if the roof will be replaced. Consider making the seller replace the roof as part of the closing terms.

Actual Cash Value Vs. Replacement Cost For T-Lock Shingles

An insurance company that provides coverage for T-lock shingles may include a high deductible or do so on an actual cash value (ACV) basis rather than pay for the replacement cost value. ACV policies are based on the item’s depreciated value while replacement cost coverage does not account for depreciation. This may leave many homeowners with no option but to pay out of pocket for repair or to replace the entire roof.
