REPAIR ROOF SHINGLES – Replace Missing Aspahlt Roofing Shingles Step by Step Guide

“An asphalt shingle roof should last between 20 and 30 years,” says Claude McGavic, executive director of The National Association of Home Inspectors. “If you have a 40-year-old roof,there could be a problem even if it looks good from the ground.”

How much time you’ve got left: Five to 10 years, depending on your roof’s condition. If you live in a development and your neighbors are all starting to replace their roofing, that could be a sign that you should do the same.

Your Contractor Starts Installing Your Roofing Materials

After the tear-off and making sure your gutters are cleaned out, your contractor is ready to install your new asphalt shingle roof. Theyll systematically work their way around the house following the sections that are torn off.

Once a section is torn off, theyll lay the underlayment and install the drip edge. Depending on the weather, theyll then start installing your starter shingles and shingles using the installation method of your choosing.

When theyre done with the shingles, theyll put on all the ridge capping. One of the very last things your contractor will install is all the vents that are needed for your roofs ventilation system.

Be aware, the life of your roof not only depends on the installers workmanship but the quality of the roofing materials as well. You should always invest in quality roofing materials to get the most out of your roof replacement.

How To Install Wood Shakes And Shingles

Before you can install wood shingles on your roof, you need to create the vent structure or sheathing. This keeps them from warping in the dampness and heat.

Once the structure is in place, plan the layout of the shingles and nail them into the sheathing. Take care to measure the shingles placement throughout the job to make sure youre on the right track.

Many homes in the United States have asphalt shingle roofs. Asphalt shingles are an attractive option when considering a roof system for your home for many reasons. Among these are appearance, expected life span, and cost. Another reason that makes asphalt shingles attractive to most homeowners is the ease of repair if minor damages occur.

How To Remove The Old Damaged Shingles

When shingles are blown off, it’s only the bottom half of a shingle that is typically damaged. What you see on a roof is only half of each shingle the other half is tucked up and under the next higher shingle. In order to replace a shingle, then, the upper half must be removed first.

  • To do this, carefully insert the pry bar between the existing upper shingle still in good repair and the damaged one, working them apart. Take care here it is quite easy to tear the shingle still in good condition, which would mean that it, too, must be replaced.
  • With the upper layer free, work the pry bar under the damaged shingle, prying upward until it is free of any nails or staples. Again, take considerable care not to damage good shingles during the process. Slide whatever is left of the damaged shingle out.
  • Drive protruding nails or staples into the roof until they are flush you don’t want them holding the new shingle higher than it should be. These nails or staples could be removed rather than driving them flat some of the shingles replaced on this job were up under the ridge cap and difficult to reach with a hammer and they were simply removed.
  • The gray areas are actually the top half of a good shingle. The bottom half of the shingle above it on the roof has been broken off and needs replacing.

    Tearing Off & Replacing an Asphalt Shingle Roof
  • Buy a bundle of shingles that match your existing roof. You might have a partial bundle left at your home from when the roof was installed. If you do, use these for an exact match.
  • Wait for a dry day to perform the repair.
  • Position the ladder in a stable location and carry your tools and supplies up to the work area.
  • Take the pry bar and lift the section of intact shingles immediately above the damaged or missing shingles. This exposes the row of nails holding down the damaged shingles.
  • Pry up the damaged shingles or any remnants still attached.
  • Use the curved end of the pry bar to remove the nails.
  • Often two rows of nails secure shingles. Use the pry bar to expose the second row and remove those nails as well.
  • Discard damaged shingles or remnants.
  • Slide the new shingle into place. Make sure that it is straight.
  • If only 1 piece of a 3-tab shingle is damaged, then you can cut a single tab from a section of new shingle and install it. Use the utility knife to cut the replacement piece.
  • Nail the new shingle to the roof deck. Each 4-foot section of 3-tab shingles requires 4 nails.
  • Re-nail shingles above the repair area where you had to take out nails.
  • Load the sealant into the caulking gun. Seal the shingle flaps down on each other to create a smooth surface.

    Do I Need To Replace My Whole Roof Or Just The Shingles

    Theres nothing worse than learning that you have to replace your entire roof. However, if this is the case, its important to do so your roof is the first line of defense against the elements, and a roof thats in bad shape not only offers poor protection, it can end up becoming a danger to your home and to your family.

    However, in some cases you can just replace the shingles on your roof and not the entire roof itself. This is, of course, a much more preferable action as it will take less time and cost much less to replace shingles than it will cost to replace the whole roof. So how exactly can you tell whether you can get by with just replacing your shingles or whether you need to replace the entire roof?

    When You Can Just Replace The Shingles

    The following are a few examples of when simply replacing damaged shingles is enough to ensure that your roof does its job and remains in good condition:

    • The shingles are cracked or torn Shingles that are cracked can be replaced individually. However, if the crack or tear is minor, you may not even have to do that you could simply have the shingle repaired with the use of roofing sealant.
    • The shingles are missing pieces If a piece of a shingle is missing, then the entire shingle will need to be replaced. This can happen if a piece of debris has been blown into your roof, thereby causing a piece of shingle to break off.
    • There are missing shingles Missing shingles will need to be replaced right away. If a shingle is missing, your roof becomes vulnerable to the elements especially wind and rain. Wind will be able to get under surrounding shingles and cause further damage, while rain may be able to leak into the area where the shingle is missing.

    The Pros Of Completely Replacing The Roof

    • Completely replacing the roof lasts longer than re-roofing.
    • It can be done no matter how many layers of shingles are on the roof.
    • Unlike, re-roofing that may cover up any issues with the deck, such as rot, which can eventually cause the roof to give out, a fully revamped roof addresses all issues for a safe and sturdier roof.
    • Saves more money over the long haul because it enables you to identify early signs of rot and sagging caused by water damage to the deck, which can eventually permit water to leak and drip down inside the walls where it can damage the drywall and flooring and lead to costly repairs.

    One Break The Seal On The Target Shingle

    The images below depict Sedona Dynasty with ArmourZone shingles.

    • In the photo below, the target shingle is located.
    • The first step obviously requires the removal of the nails holding that shingle to the roof deck. To access the nails, the shingle will need to be lifted, but it is likely bonded to the shingle below by the shingles asphalt sealant spots. Although this sealant bond is quite strong , it can be broken by sliding a flat pry bar carefully under the target shingles edge.
    • This sealant separation is best done in cool weather, as the sealant bond will be more easily sheared by the pry bar when cool in hotter weather, the sealant will be more gooey and tenacious, and harder to separate cleanly.

    A word of caution: In cooler weather, the shingles will be stiffer than in warmer weather. Exercise care to avoid distorting the shingles more than necessary.

    Install Step And Dormer Flashing

    It’s possible to reuse existing step flashing and dormer flashing, but the best way to get a watertight seal is to tear off the siding in those areas and install new flashing. Start by running self-stick underlayment at least 6 in. up onto the walls. This provides an additional barrier if water does get past the flashing. Cover the front wall first and then work your way up the side wall. Overlap the sidewall underlayment around the corner onto the front wall about 1 in. or so.

    Install the shingles right up to the front wall. Cut a couple of inches off the vertical portion of the dormer flashing, and run the horizontal portion past the side wall that same distance. Nail the dormer flashing to both the wall and the shingles.

    Make a 1- to 2-in. cut with a tin snips at the bend in the first step flashing. Run a bead of sealant on the corner edge of the dormer flashing, and then run that step flashing past the dormer flashing the same distance you made your cut. Bend the step flashing around the corner onto the dormer flashing with your hammer.

    Install your next row of shingles over that first step flashing, then cover that row with a step flashing, and so on. Nail the step flashing to the wall toward the top of the flashing at the end that’s closer to the peak, so the next step flashing in line will cover the nail. Don’t nail them down through the shingles. For information about flashing around chimneys, see Installing Chimney Flashing.

    How To Replace Damaged Shingles

  • With the area prepared , slide the new shingle into place. Line up the bottom of the shingle with adjacent shingles to each side. The new shingle will not quite fill the gap between the shingles on either side equalize the gaps between shingles side to side. You may find that the shingle needs to be lifted slightly to slide over staples, nails, or the next shingle slide a hand up under it and carefully lift slightly.
  • Very carefully roll up the shingle just above the replacement until the tar line is well exposed as this is where the nails should be driven in.
  • Drive two nails on each tab, or six nails per shingle. The nails, if driven through that tar line, will hold both the new shingle and the one beneath it.
  • Allow the upper, rolled-up shingle to relax back into place, helping with a little hand pressure. As shown in the photo, it is a good idea if possible to apply a little heat to help melt the tar and seal the new shingle to the older existing one underneath it.
  • The job pictured needed replacement of four shingles, plus one that was damaged in the process of “unsticking” it from the broken one, for a total of five. It took about an hour to do the task a small amount of effort to protect the investment of your home.
  • The upper shingle is curled up, revealing the nailing area. The nail is placed on the tar line and driven through both the new shingle and the older shingle underneath it.

    Your Asphalt Roof Was Damaged From A Storm

    How to Replace a Roof Shingle (DIY)

    The weather where you live and the kind of storms your roof faces factor into how much wear and tear it goes through. But that isnt the only thing you have to worry about when it comes to weather.

    This may seem obvious, but heavy storm damage will also lead to a roof replacement. If high winds come through and rip up your shingles or a tree falls on your roof then clearly youre going to need a new one.

    If you have a metal roof system, then hail damage to your metal panels will lead to a replacement if the integrity of the metal is compromised. But for an asphalt shingle roof to be replaced from hail it has to cause damage to the soft metals that are on your roof.

    Whatever kind of storm damage your roof has, its important to know if your roof is covered. Read this article on replacing your roof through homeowners insurance.
