A stone chimney consists of a stone facing in place of brick or plaster. A chimney is an independent structure in the sense that it is not connected to the house frame. Due to this, the joints around a chimney are prone to leaks when it rains. When the joints are not properly sealed, water will leak into the ceiling and you will you notice ring stains on the ceiling plasterboard. To prevent this from happening, you must tightly fit the flashing around the chimney. Flashing is water-resistant and made from various materials like aluminum, galvanized iron, zinc, copper and steel sheets. How you install the flashing will also determine its effectiveness. Here are some useful tips:
Roof Material and Type
Since the flashing around the stone chimney should be attached to the roof and chimney wall, you should find out what your roof is made of. Some roof materials are easy to work with and some are complex. For example, you can install the flashing on your own if the roof consists of asphalt tiles and wood shingles. Nonetheless, roofs made of tile or slate are complicated and the flashing installation should be done by a professional.
Cutting and Measurements
To make the flashing installation easy, you should not do the bending and cutting on site on the roof. Simply measure the chimney girth and inclines where it meets the roof. Use these measurements to cut the right size of flashing in your garage. It is advisable to have the metal workshop do the cutting for you, as they use special equipment for the job. Some of the equipment that you might need includes a pry bar, masonry bit, polyurethane caulk, drive-in anchors and an ice/water water barrier roll.
