Even though slate roofs are highly durable, at some point, they will need repair work. Depending on the depth of the problem with the roofing, a total replacement might be necessary. If you are unsure whether or not it is time to repair or replace your slate roof, here are some signs to look for.
Moisture and Rot
Ideally, your slate roof should insulate your home from outside moisture. However, as the roofing deteriorates, you will notice moisture, mold, and rot developing in your attic and other areas. At the first sign of moisture, it is important to contact a professional for a roof inspection. If you wait, rot could develop and that would make your home structurally unsound.
When assessing your roof for signs of moisture, pay close attention to the area around the ventilation pipes and the attic. Look for water stains or mold growth. You also need to check the attic insulation for moisture.
Over time, your roofing tiles can become brittle and crack. Elements such as rain and sunlight can take a toll on your slate roof. The slates can also crack if they were poorly installed by the original contractor. In addition to these reasons, slate also naturally expands, which can cause cracking.
Having the cracked tiles assessed and repaired immediately is important because the cracks could be a sign that there is an underlying issue, such as damaged flashing. If assessed early enough, you could potentially avoid a complete replacement of your roofing.
Missing or Slipping Tiles
Slate tiles are held into position with special roofing nails. Over time, the nails start to corrode. When that happens, the tiles on your roof can start to slip and eventually fall off. As a result, your roofing will allow elements such as rain to slip into your home.
Even if your tiles have not fallen off the roof, there is a possibility that they have slipped. If the edges of the slates do not line up as they did before, there could be some slippage.
Since all of your tiles were installed at the same time, when a few slip off the roof, it is time for a complete assessment of your roofing. If you wait and a storm hits, your home could potentially be flooded with rain water.
Talk to your roofing contractor to learn about other signs of damage you should be on the lookout for. Check out websites like http://www.stevensroofingcorp.com for more information.Share
