8. What should be done when using metal to repair splits in wood shingles?

Answer: D

Explanation:

The metal should be slid under the split and the bottom edge of the metal should be bent 90 degrees to hold it in place.

This method effectively secures the metal in place while providing support to the damaged wood shingles, ensuring a more durable repair.

A) All exposed nails should be sealed with roofing cement.

While sealing exposed nails with roofing cement is a good practice to prevent leaks, it does not address the specific issue of repairing splits in wood shingles. This option does not provide a direct solution to hold the metal in place or repair the split itself.

B) A new shake or shingle should be installed over the metal.

Installing a new shake or shingle over the metal may cover the repair but does not effectively secure the metal underneath. This option overlooks the crucial step of properly placing and securing the metal to support the split, which is necessary for a long-lasting repair.

C) New felt paper should be slipped between the metal and the damaged shake or shingle.

While adding felt paper may provide some level of protection, it does not address the requirement of securing the metal properly. This option fails to provide a reliable method for holding the metal in place, which is essential for effectively repairing the split.

D) The metal should be slid under the split and the bottom edge of the metal should be bent 90 degrees to hold it in place.

This option provides a practical and effective solution for repairing splits in wood shingles. By sliding the metal under the split and bending it, the repair is secured properly, ensuring that the damaged area is reinforced and less likely to fail again.

Conclusion

Option D is the most effective method for repairing splits in wood shingles, as it directly addresses the need to secure the metal and support the damaged area. The other options either do not provide a comprehensive solution or miss the critical step of anchoring the metal in place, making them less effective for this specific repair task.
