Sheathing can be repaired using a variety of methods. Depending on the nature and extent of the damage, you may need to replace sections or all of the sheathing. In cases where only small areas are affected, nail-on patches can be used to repair holes or splits in sheathing boards. A patch should overlap the damaged area by at least 3 inches on all sides and be fastened securely with galvanized roofing nails. To repair larger areas, you can use a piece of plywood or oriented strand board (OSB) cut to size and nailed into place over the damaged area. If there is extensive damage, it may be necessary to completely replace the sheathing. Be sure to use the same type of material when replacing sheathing and be sure to attach it securely with nails. Following these steps can help ensure that your roof decking is strong, durable, and in good condition.
In addition to repairing damage to the roof sheathing, you may also need to inspect and repair flashing around chimneys, skylights, and other protrusions in your home’s roof. Flashing is a metal or plastic material that is used to create a water-tight seal around these areas. If the flashing is damaged or missing, it can lead to leaks. Inspect the flashing regularly for signs of wear and tear, and repair or replace it as needed.
Finally, you should check your roof for signs of wear and tear or damage due to wind and weather. Look for missing, cracked, or buckled shingles; discoloration; granule loss; dents in metal flashings; or any other signs of deterioration. If any of these issues are present, it is important to have them addressed as soon as possible to prevent further damage.
