Tar and gravel roof repair is a common on flat or build-up roofed structures. The roof covering is a layered combination of asphalt and roof membrane, covered with small gravel. Though prone to leaks, it is fairly simple to repair with roofing tar and patience. If you tend to get the flour all over you when baking or transform yourself into a work of spaghetti art when painting, you may opt to wear coveralls for repair jobs with roofing tar.
Because the source of the leak may be many feet away from where it is showing upon your ceiling inside the house, check anywhere the water may flow between roofing sections and especially any flashing for roofing vents, turbines, fans and skylights. A really good indication of a possible leak is any area where the gravel is missing and the asphalt is damp.
Once you find the source of the leak, clear the area of gravel, dust and debris so that the asphalt is totally exposed. Now you can patch the roof with by using a trowel to apply the tar evenly and smooth out several inches beyond the actual leak source. Roofing fabric is then laid over the tar with another application of tar spread on top to complete the patch. Make sure that all the edges of the fabric are smooth and that the patch is feathered on the perimeter to create a seamless integration with the roof.
The last step is to replace the gravel over the patch for a complete tar and gravel roof repair. Make sure you have a roofing contractor check your roof annually for leaks.
