Water causes more damage to chimneys than we might think. The other parts of your house are protected by the roof, the drip flashing, the fire-wall and the eave, but it does not protect your chimney which stands bravely on top of the roof. It is constantly exposed to snow, thaw, rain, animal invasions, leafs and branches. A chimney cap avoids many troubles.
Of course, there are many different types of chimney and chimney caps. Always make sure that the chimney cap fits the chimney or appliance.
Don’t forget the chimney sweeping and the drip flashing verification to avoid water infiltration.
