Here are detailed explanations for fixing the three most typical issues with asphalt shingles.
When Should Shingles Be Replaced on a Roof?
Water may get under the shingles and ruin the wood sheathing below, so any damage or symptoms of deterioration need prompt attention. Putting off fixing an issue, no matter how minor it may seem, may increase the cost of a roof replacement by hundreds of dollars or more.
The shingles on a roof that is more than 20 years old and has significant damage or wear should be replaced. If your roof is structurally solid and has a shallow pitch that you're comfortable with, you can do the necessary repairs independently.
1. Changing the shingles on the roof
If a shingle is damaged, the entire shingle must be replaced. Check to see if any shingles were left over from the last time the roof was repaired (perhaps the builder or roofer who did the work left some behind). If not, you may purchase a bundle of shingles from a hardware store or a lumber yard for $15 to $20 per square (100 square feet). If a perfect fit is impossible, settle for the next best option.
A hammer, a flat pry bar, a utility knife, and several 11/4-inch roofing nails are all you need to replace a broken shingle. After being nailed down with four nails each, the next course of shingles is fastened by driving its nails through the ridge of the shingles below.
To remove the first row of nails, position the pry bar underneath the shingle directly above the damaged one and pull gently to dislodge it from the sealant strip. The bottom row of nails will be visible.
Lift the damaged shingle by sliding the pry bar beneath it. Please remove the pry bar, push the shingle down, and remove the nail after it has popped up approximately 1/4 in. The remaining three nails will need the same treatment. Then, remove the second row of nails by pushing the pry bar under the shingle directly above the damaged one. Snatch the shingle's eight nails and pry it off the roof.

How to Lay Roofing Shingles
Second, caulk the curved edges of the roof shingles.
Curling of the corners, either downwards or upwards, is a common sign of age in asphalt shingles. The curling of shingles may be prevented if the curled portion is glued down as soon as it is seen.
Use a caulking gun to apply roofing sealant (approximately $4 per 10-ounce tube) beneath the corner. Put some weight on it, like a block (right), and keep it there for at least 24 hours to dry the sealant. That's the whole deal.
Patching Up Broken Roofing Shingles
Replacing a shingle is unnecessary if the damage is minor, such as a fracture or tear. To begin with, a roofing sealant should be applied in a thick bead beneath the crack. A second bead of sealant should be applied on top of the crack as the shingle is pressed down. Use a putty knife to distribute the sealant evenly.
The great thing about this solution is that you can implement it without knowing you implemented it. It's simple to hide: Inspect the downspout for a buildup of granules of varying colors that may have washed off the shingles. Then, scoop a few into a cup and use them to cover the sealant.
