A repair is usually the best option when the issue is localized and your roof is still relatively young. Consider repairing if:
Damage is limited to one area
If only a small section has missing shingles or damaged flashing, a targeted repair can be the best option.
Your roof is only a few years old
In Texas, asphalt roofs last an average of 12 to 15 years. If yours is only a few years old and has not been damaged by hail or significant wind, a repair could be the right call.
You need a short-term solution
If you plan to sell your home soon, or need a temporary fix before a larger project, a repair may be the practical choice.
Replacement is usually smarter when problems are widespread or your roof is nearing the end of its lifespan. Consider replacement if:
Damage is extensive
If a large amount of your roof is affected, repairs become patchwork and can cost nearly as much as a replacement.
The roof is nearing the end of its life
Even if damage looks minor, an aging roof may fail sooner rather than later, and replacing it prevents repeated repair bills. Check whether your insurance carrier will diminish your coverage because of an older roof — many policies are changing in Texas.
You have multiple leaks
Several leak points usually indicate underlying system failure rather than isolated damage.
Storm damage compromised the system
After major hail or wind, roof damage is not always visible from the ground, but it can shorten roof life significantly. Keep in mind that your insurance company expects owners to take steps to mitigate further damage. Insurance may cover sudden and accidental damage, but not additional damage that happens because the owner failed to act.
