How can I repair a sagging roof?

The first step in fixing the sagged roof is to identify the cause of SAG. In most cases, the sagging roof is caused by a broken rafter or roof deck, but in some more serious cases the basic cause of the problem may be damaged or sink the foundation. You will have to get up in the attic and carefully explore the roof to discover the basic cause. Once you find out the cause, you will need to determine the best procedure for solving damage.

It is best to make all repairs from the top of the roof, which means that in some cases you have to tear shingles and other covers. This may not be possible if you notice the sagged roofs in winter, when it is likely to reduce snow, which means that you will need to repair under the roof in the attic. This can be difficult and dangerous, and if possible, you should avoid it. Torning shingles and deck can be more expensive, but it's safer and more efficient.

Specific repairs you will need to make will vary depending on the type of damage has suffered the roof. Broken rafters can be particularly difficult to repair, especially from the roof; Returning of two broken pieces of rafters to the original position can be made using a L-mildew, but the jacks may be necessary to lift the pieces until they are flushed. The decline can also be completely replaced, but it is a much more significant repair that may include the removal of significant parts of the roof deck and shingles.

If the sagged roof is caused by rot or deformation of the roof deck, the repair will be much easier. You will have to remove shingles and old decks, which means that the roof will be an exposed hole. This can be problematic in the winter months, but allowing the roof to continue with SAG can lead to greater problems such as the cave. The deck will have to be removed from the top of the roof because the shingles will have to be removed and then replaced. IfIt is necessary to strengthen the deck, new lumber may be added under the deck rather than replace older supports.
