Roofing, Flashings, and Chimneys
Repairing Chimney Flashing Easily
Once you have completed the inspection of the chimney, take a look at the flashing and shingles around the chimney. If the shingles around the chimney are cracked or have holes then repairing the chimney flashing area is easily accomplished by sealing the shingles and the chimney flashing with an elastomeric roof coating. If you do not want unsightly black patches on your roof use a clear elastomeric roof coating designed for asphalt shingles.
Before applying the elastomeric roof coating, fill the cracks and holes with clear exterior elastomeric caulk. Next, following the manufactures instructions apply the elastomeric roof coating.
Although the best time for repairing chimney flashing is in warmer weather, some elastomeric roof coatings and caulk can be applied in below freezing and even on a damp roof surface.
You live in an area with a rapid freeze-thaw cycle and you use the fireplace intermittently. This especially true for wood-burning fireplaces. The biggest culprit is moisture. What starts out as water vapor becomes tiny droplets of water. These droplets settle into fissures in your chimney - and freeze if when the temperature drops and you're not using your fireplace.
Then, since it's gotten cold again, you fire up the fireplace, and melt that water. The next day you decide not to have a fire - and the water freezes into those fissures, spreading them open like a pair of pliers. A couple of winters of this, and you have a real problem.
You live in an area that's just plain cold. Long, cold winters also put heavy wear-and-tear on the chimney. Again, moisture is the problem. Water is called the "universal solvent" for a reason - it'll dissolve anything given enough time. Look at the Grand Canyon.
In many cases the damage of a chimney is so substantial that tuckpointing will not work. When this happens a chimney, and/or fireplace, rebuild is necessary. As a result of direct exposure to all aspects of weather (especially freeze-thaw cycles), the mortar that keeps the bricks held together will crack, allowing water entry. The brickwork is porous and becomes saturated. This creates the framework of the brick to degrade, which causes a safety concern for the chimney and for your home.
Does Your Chimney Need to Be Repaired?
When you get lots of moisture in a chimney, the water's solvent properties go to work on the water, concrete and bricks, slowing removing one particle at a time until you have fissures, and eventually, cracks, especially if you don't have a flue liner or other flue protection. If you're getting heavy use out of a chimney, you'll speed up the deterioration process.
You have a high-energy efficiency furnace. Today's high-efficiency furnaces save you money, but they also put a lot more moisture in the flue air than yesterday's lower-efficiency ones. All that moisture, again, increases the wear-and-tear on your chimney and flue.
You have an oil or gas furnace. In these cases, the problem is acid. Acidic vapors from burning gas and oil build up a residue and that eats away at your chimney from the inside out. This can cause cracks in the clay lining, especially, and leave you with potentially expensive repairs.
Anyone that is dealing with a chimney that is settling or pulling away from a home needs to consult with a professional chimney repair company at once. There are many reasons why chimneys begin to detach from the rest of the home. The most cited reason is that the home is built on unsettled ground.
This can ultimately cause the heaviest part of a home, which is usually the flue, to detach as the ground or base begins to settle. This occurrence will make the vent very unstable and it does cause a significant safety hazard. Individuals that have chimney structural issues will need to consult with a professional company to fix the problem.
There are a number of solutions for a leaning chimney and some are better than others. One way to address the issue is with metal bars or cables. The contractor may suggest strapping the flue to the rest of the house for stability. This process involves adhering the flue to the rest of the home using a very strong material such as a metal strap.
