Bur Tar & Gravel Or Other Asphalt Roofs Perform Poorly With Insulation

Most contractors will not recommend a BUR roof is installed with underlying insulation, since the roof membrane is usually stretched towards the edges of the roof where there is no insulation. This causes stretching of the membrane since the roof tends to heat or cool faster in these areas, causing both excessive contraction and expansion of the roof membrane. This is in sharp contrast to the rest of the roof membrane, which will not shrink or stretch as much, due to underlying insulation. This tug of war causes wear and tear on the roof membrane, especially near the edge of a roof. In the case of a BUR roof, without reflective coatings, the surface temperature can exceed 150 degrees Fahrenheit on a summer day. Cooking a roof membrane like this can cause it to tear and crack prematurely. And once a roof membrane is compromised, water can seep in and quickly cause large areas of a roof to deteriorate. Just a few months of water penetration can cause major deterioration of a roof membrane.
