Over time, your roofing underlayment or sheathing will need replacements, especially if it’s been more than 20 years servicing your property. True enough, your roofing material plays the biggest role when it comes to protecting your property against rain, hail, and snowstorms. However, the sheathing is the attic’s first line of defense against water damage, and it will definitely face big trouble if the roof sheathing gives way to damages.

You’ve done some research, and you’ve seen numerous guides telling you it’s important to have roof sheathing replacement soon. In fact, some websites encourage you to perform these repairs by yourself. It does look easy: just get a ladder, climb your roof, remove the plywood and damaged underlayment right after you’ve removed your roofing material.

In fact, it’s enjoyable to shop for top-quality roofing equipment that your dependable Calgary AB roofers also own. Unfortunately, it’s a huge investment for homeowners to purchase top-quality equipment for a single roof sheathing repair job. If you’re planning to make roofing and roof sheathing repair a career, then this is a worthwhile buy.

However, going up a ladder and traversing the heights of your roof — no matter how high it is off the ground — can be nauseating. Additionally, most individuals that perform home DIY roof repairs of any kind have no safety harnesses to protect them from any possible slip or trip that can send them down the roof.

Removing the roofing material, plywood, and sheathing will require considerable force with the pry bar, and you can get yourself off-balance if you use too much force in removing the material. Therefore, we highly advise that unless you have an apprentice’s experience in roofing, it’s better to work with roofing professionals for all your roofing needs.

If you’d like to know more about the usual roof sheathing replacement process, SF Gate Homeguides has an in-depth list of steps to help you.

  1. Unroll roofing underlayment the length of any valleys on the roof where sections join. Cut the underlayment with a utility knife. Center the underlayment over the valley. Nail it into the sheathing with corrosion-resistant nails long enough to penetrate at least 3/4 inch into the plywood sheathing. Space the nails 12 inches apart along the outside edge of the underlayment.

  2. Unroll approximately 5 feet of underlayment horizontally on the roof so one long edge is even with the bottom edge of the roof. Adjust the underlayment so it is square and level, using a carpenter’s level. Secure the bottom edge with the same nails used in the previous step. Space these nails 24 inches apart. Secure the top edge with nails spaced 36 inches apart.

  3. Continue to unroll the underlayment in 5-foot sections and fasten it down. Overlap ends of the underlayment on the bottom row, if necessary, by 6 inches as you begin a new roll of underlayment. Continue to add more underlayment to finish out the first row. Nail it into position.

  4. Measure and mark 4 inches from the top side of the underlayment. Snap a chalk line to connect your marks. This becomes the placement line for the bottom edge of the next row of underlayment. (Continued)
