This Lock On All-Weather
Protection Requires No Key
|
|
Custom Lok 25 is
interwoven
with adjoining shingles in four
different locaions and is securely nailed down its four critical
points for outstanding resistance to blow-off.
|
In cold, windy and otherwise harsh climates, the wrong choice of shingle
can become obvious the first big storm after installation. But if your choice is Custom
Lok 25, you can ride out one
storm after the next with confidence- these shingles have been custom designed to provide
all-weather protection. Custom Lok 25 shingles interlock with adjoining
shingles at four different points and are securely anchored in just as many. As a result, the overlaps provide
double protection and the roof locks down tight to help protect against
the tearing and blow-off that can occur during high winds. What’s more, Custom
Lok 25 is constructed on a heavy-duty, asphalt-saturated organic felt base which
makes it less brittle in cold weather and flexible enough to withstand tucking and
locking without tearing. This extremely tough shingle is ASTM certified to
provide Type II Wind Resistance and 8-way protection against wind.
Available in a range of colors, Custom Lok 25 is suitable for new construction or
reroofing of homes, farm buildings and light commercial structures.

Exclusive
Protection Program
Custom Lok 25 carries a 25-year limited transferable warranty plus five years of
SureStart protection. This exclusive plan provides extra protection in the
early years when manufacturing defects are most likely
to appear. And although they rarely do, its reassuring to know that 100%
of the replacement costs for materials and labor are covered during the 5-year
SureStart period following installation. |
