Flat roofs require proper maintenance in order to serve their purpose and last long. There are times, however, when unavoidable circumstances happen, and your flat roof is damaged. Its metallic materials can turn rusty. The nails can become loose. The roof can collect moss and mildew. It can leak. This is why it is important that you know these three handy roof repair tips.
1. Find cracks and leaks by brushing away debris and whatever else covers your roof.
You might not know it, but your roof may already be covered with moss and mildew. Or it may have a lot of cracks already. You don’t know this because you cannot see them. So the first thing you should do is clean and brush away all the dirt and debris that has gathered on your roof. After cleaning, this is when you will find the cracks and leaks that tell you the roof is scheduled for repair – or for replacement.
2. Find a good cutting tool you can use to repair your roof.
What will you need the cutting knife for? It will take care of all the blistering that has developed on your roof. Cutting through the blister with the cutting knife is the first thing you need to do. Slowly, cut the whole layer, but do so carefully, so you won’t add more damage to the roof. Then remove all the water that you find inside the blister and let it dry. Be sure that your cutting knife is sharp.
3. Repair all leaks, cracks, and holes.
Find a good urethane roof cement for the leaks, holes, and cracks. After spreading the roof cement on the area/s, cover it with steel mesh. Once again, spread some cement, but this time on top of the roof mesh. Place another mesh on top, press it and coat with the final layer of cement. Do not forget to flatten and smoothen it.
As for the rusted surface, clean it with water and detergent first. Be sure that all the moss and mold that may have grown on it is thoroughly removed. Remove all rusted screws and place new ones. Scrub the surface rust using a wire brush. Then use an 80-grit wet/dry sandpaper on it.
