Bergen County Roofing: Article About Slate Tile Roofing Problems
Many homeowners choose slate roofing because it offers natural beauty, durability and longevity. In fact, slate roofs that are well-maintained are known to last for at least 100 years. However, homeowners should still have their slate roof inspected by a Bergen County roofing professional at least twice per year. These inspections are usually performed during milder weather months, and they can help identify any issues that need to be fixed before they become more significant problems. Homeowners who have a slate roof or who are considering installing a slate roof on their home should be aware of the most common problems with this roofing material.
Issues such as broken tiles are among the most common associated with slate roofing. This happens on homes in areas that are prone to heavy storms. Broken tiles are also common on homes with large trees around the roof. Homeowners should hire an experienced slate roofer to individually repair the slate tiles that have been damaged. Homeowners may be concerned by slate tile corners that are chipped, but they are only an aesthetic, rather than a functional, concern. Slate tiles that are badly damaged or missing, however, will need to be replaced as soon as possible.
Another common problem with slate roofs is related to the flashing, which is often associated with problems on other types of roofing systems as well.

Flashing is the metal material that is located in areas where the roof has projections or intersections, such as chimneys, pipes and valleys. With slate roofing tiles, the flashing is usually made from galvanized steel or copper. Copper flashing does not require any maintenance and is known to last about 70 years. Copper is often chosen for its natural beauty as well. Flashing made of galvanized metal, on the other hand, will need to be routinely painted to provide further protection from rust. This type of flashing will need to be replaced about every 15 to 20 years. Although it is less expensive than copper, galvanized flashing may not be ideal for homeowners who want a low-maintenance roof.
Slate tile roofs also have gutters like most other roofing systems. Gutters and downspouts need to be regularly maintained and professionally inspected. Similar to galvanized flashing, galvanized gutters and downspouts will need to be painted every now and then to help prevent rusting. Homeowners should have their gutters cleaned at least once or twice per year to keep water properly flowing away from the roof.
