How to Reroof a Steep Pitched Roof
You can reroof a steep roof, but you will need to take extra safety precautions. With the proper tools and materials, this home improvement job will probably take a minimum of 2 days to complete, providing the weather is clear. Follow the simple steps belsow to reroof your own steep roof.
Step 1 – Safety
You will need the right equipment to be safe while you work. Scaffolding and rappelling gear will provide the safety you need. Be sure you have all of your tools and materials with you and that you can get to them readily. The tools and materials should also be in a secure location so as to prevent them from falling. Consider connecting some of your tools to a bungee cord. Always put on protective eyewear, work gloves and work boots while you are roofing.
Step 2 – Removing the Old Shingles
Use the shovel to pry the old shingles from the roof decking. If any nails will not come free, drive them into the decking with your hammer.
Step 3 – Replacing Rotten Plywood
Check to be sure that the plywood that was under the shingles is still in good condition. Any wood that has become rotten should be replaced. The new plywood should have the same thickness as the wood you remove. Be sure to mark the wood to be replaced and include the area over the middle of the rafters. Use the circular saw to cut the wood to be removed. Secure the new plywood into place.
Step 4 – Determining the Amount of Shingles Needed
Estimate the number of shingles you will need for your reroofing job. Generally, shingles are bundled in groups of 30. An area measuring 10x10 feet will require 3 bundles of shingles.
Step 5 – Securing the Felt Paper
Use felt nails to secure felt paper to the entire roof. The first sheet of felt paper should be secured in line with the bottom of the roof. Cut the paper with the razor knife at the end of the roof. Continue the process, overlapping the paper about 5 inches as you go, until the roof is completely covered.
Step 6 – Chalking the Shingle Lines
Use the chalk lining to mark a line twelve inches from the the bottom of the roof. Continue marking the roof with the chalk line every six inches after that.
Step 7 - Attaching the Shingles
Generally, shingle dimensions are 1x3 feet. Install the first shingle with the tabs pointing toward the roof top. The following shingles should be installed with the tabs pointing toward the bottom of the roof. Each shingle should overlap the one before it. One nail should be placed in each tab of the shingle. Continue installing all of the shingles until the entire roof is covered.
