GRAVEL ROOFS AND THE PACE ROOF RENEWAL SYSTEM
GRAVEL ROOFS -- RELIC OF THE DARK AGES. HOW TO BRING THEM BACK TO LIFE SAVING THE HIGH COST OF A NEW ROOF!
The gravel roof is completely unnecessary in this day and age. Back in the days of the old locomotive steam engine with coal and hot ashes flying off onto roofs of buildings alongside railroad tracks, there was purpose. But not today. All a gravel roof accomplishes is a convenient place for a roof contractor to bury his mistakes where nobody can see them. The average gravel roof has 400lbs of gravel per 100sq.ft putting strain and stress every time there is the slightest expansion or contraction. This tells a lot why gravel roofs fail.
We've often used the comparison of the old style barbecue pit to explain the second weakness in a gravel roof. Gravel or stone was put in the bottom of the pit to retain the heat. In the same way, the gravel on a roof draws the intense heat of the sun, then retains it to burn out the life of the roof mat. Using our PACE method of roof renewal, building owners get all the horrible, unnecessary weight off the roof. Even in cases where gravel is deeply imbedded and sweeping won't remove all of it, you reduce the heat factor as much as 90%. Removing the weight eliminates the danger of roof sagging, makes the building safer. And you improve the visibility factor, making it easy to detect defects in the future roof maintenance program.
