A Mod Bit roof is a hybrid BUR that typically comes in rolled sheets. The sheets are either hot-mopped (using heated asphalt), torch-applied to the roof, or cold applied using adhesives. If the seams are inadequately heated, voids and blisters can result. Over time, weak seams and flashing details age and crack, causing leaks.
The surface of the applied sheet is often granulated. Before applying a Roof Restoration System, it is recommended that loose granules are swept or power-washed off; the remaining granules can then be “locked down” with Coatings.
Traditional asphalt-based roofing weathers from the bottom-up. The oils leach from the asphalt, leaving a dry, brittle substrate. As a result, the roof is less flexible and less able to expand/contract with the building as it heats/cools throughout the day.
Dark colored asphalt-based roofs heat up quickly and can reach temperatures of over 190°F. If an afternoon thundershower appears, the rain rapidly cools the roof surface. The asphaltic roof surface doesn’t handle this drastic temperature change well, resulting in thermal shock causing cracks and premature weathering.
As a Mod Bit weathers, it cracks – resulting in leaks.
As the Mod Bit seams become weathered and brittle, they begin to pull apart from one another, causing leaks.
Traditional asphaltic roofing was Designed to be torn off and replaced. Roof Restoration Systems can extend that roof’s life cycle by protecting it from the #1 threat: the sun. A seamless roof coating system is a cost-effective solution to a full roof tear off.
