Tar & Gravel roofs have been around for centuries. Constructed by layering asphalt and felt then finishing the system with a heavy coat of asphalt and gravel, these systems are used primarily on large commercial flat roof area. Tar & Gravel usage has been replaced with more effective modern systems.
As a roof expands and contracts the roof system moves. This is a daily occurrence and is associated with Thermal Shock. During movement the membrane binds against each other. Sometimes a tree branch or flying debris may impact the roof causing damage. 3rd party damage is another issue. As people walk across the roof they can cause damage. The membrane on this roof has been damaged. Since this leaves the underlayment showing, it is our recommendation these areas are repaired.
Tar & Gravel roof construction starts with layers of fiberglass felt paper and asphalt. This intermat is not a waterproofing layer until it is layered with asphalt and more fiberglasses felt paper. Over time the membrane surface wears down. Eventually the fiberglass felt will become exposed. It is generally accepted that when this occurs it is time to replace the roof. Without the fiberglass intermat holding the roof’s waterproofing construction together the membrane can no longer withstand thermal shock (expansion and contraction) and will crack, possibly allowing seepage.
Tri County Roofing and Siding gives back to the community.
We understand the value of community. Tri County leaders have lived in the Charleston area for several generations. All of our employees live in the area. We understand that generosity strengthens a community, and that a vital community is important to everyone.
Tri County Roofing and Siding is actively involved in innovative community outreach. We sponsor community events and organizations such as Little League teams, and high school football games. We’ve also been active in the following community outreach programs:
In 2010, we partnered with this Salvation Army program to provide a free Christmas roof to someone in the community in need. Tri County Roofing and Siding donated the labor and GAF donated the shingles. The program had more than 3,000 applicants. Tri County provided a Christmas roof, at no charge, for a cancer patient. When that person passed on, Tri County provided another roof for a woman with a serious medical condition.
