Mother Nature at its best !
DO NOT be fooled by inferior roofing products. The average life expectancy for a properly installed tar and gravel roof is over 25 years, we have installed thousands of tar & Gravel roofs with just as many satisfied customers. It is a multi ply roof system in which it's installation is somewhat like baking a croissant.
The tar is safely heated in a Hot Tar Pot to a pourable 450 degrees, after preparing your deck whether it be wood, concrete or metal, if specified, insulation is installed. (recommended for R-Value and / or taper systems)
A Vapor Barrier Base sheet and layers of perforated felt are mopped with the hot asphalt to the prepared deck to create built up plies. Depending on the specs, there are 3, 4 & 5 ply Tar & Gravel roof systems available.
On top of the plies of tar and felt a final flood coat of Hot Asphalt is applied as washed pea gravel or washed Colored natural stone is fanned into the hot tar. Then a final layer of gravel is spread atop the embedded rock which creates the ultimate UV protection.
The top layer of rock is designed to take the elements of nature, hard driving rain, sleet, hail, snow and ice are no threat to the rock as it moves around on-top of the embedded rock, protecting the asphalt from the elements of freeze and thaw as well as contraction and expansion and the weight of the water and snow.
Base and Wall flashings are mopped with cap sheet and properly terminated. All Metal, soldered pipe flashings, Custom Gravel Stop eve metals, thick Gauge counter and wall flashings are custom made and installed at walls, curbs and chimneys.
We are keeping our Custom detail secrets off line, but will be in your estimate specifications and on your roof!
