Asphalt shingles have an average lifespan of between 15 and 30 years. Some high-quality materials can last for as long as 50 years.
Generally, the longevity of asphalt roof shingles depends on these factors:
The climate in your area—roofs in warm and sunnier climates typically need replacement sooner than those in cooler, shady climates.
Your attic’s ventilation
Quality of materials used
Proper installation
Keeping up with maintenance
If the damage is minor and the repair cost is relatively low, it’s probably worth repairing your shingles. However, if the damage is extensive or the shingles are quite old, repairing them might only postpone the inevitable. In that case, it might be better to replace the shingles completely.
To determine the best solution, check for signs of wear across the roof. If you’re noticing collections of mineral granules in common drainage areas, this is a sign that the roof's protective coating has worn away. If this is the case, then repairing roof shingles individually probably won’t equate to a long-term solution.
Before you hire a roofing contractor, ask several questions. The answers to these questions will help you gauge the quality of service you can expect from the roofer.
Are your workers licensed? (Ask this question depending on the state in which you live.)
Can you provide proof of liability and worker’s comp insurance?
What permits are necessary, and are these included in the estimate?
What is the quality warranty for work done on the roof?
What types of damage aren’t included in that warranty?
If the roof requires replacement, does removing the old roof factor into the cost estimate? What will you do with the leftover debris?
Do you use ladder stabilizers or standoffs to protect the gutters?
How will you protect my landscaping while working on the roof?
What are the plans to clean up the property after the repairs are complete?
What will you do if there’s bad weather during my repair project?
Is your company doing the project, or will you work with a subcontractor?
If you’re hiring someone to repair or replace your roof, you want to ensure they’ll do exactly what you need at a reasonable cost. On top of that, all costs should factor into your initial estimate with no hidden fees. You should also ensure they’ll be respectful of your landscaping, gutters, siding, and all other parts of your property.
Installing a new roof costs $8,844 on average, with most homeowners spending between $5,660 and $12,060 depending on the roof’s size. Other factors, like the roof's pitch and geographic location, may also affect how much you pay. Generally, the total cost breaks down to about 40% for materials and 60% for labor.
