Repair or Replace — How to Actually Think About This
Most contractors will lean toward whatever makes them more money. That's not cynical — it's just real. Which is why it's worth understanding the math yourself before you get into a conversation about it.
Replacement starts to make sense when:
- The roof is 20-25+ years old and showing widespread granule loss, curling, or brittleness. At that point, you're patching something that's going to keep failing.
- There are multiple active leak points. One flashing failure is a repair. Three separate places letting in water across different sections means the system is failing broadly.
- The deck has moisture damage. Once the plywood sheathing is saturated or rotting, shingles on top of it are irrelevant. You need to fix the foundation first.
- Repair cost is approaching half of replacement cost. If a repair quote is $4,000 on a roof where replacement is $12,000, you're not saving money — you're delaying the inevitable and adding another repair bill to the timeline.
- You're planning to sell. A replaced roof is a clean disclosure. A patched one invites negotiation.
None of this is definitive without a contractor looking at it in person. But it gives you a frame for the conversation so you're not just taking someone's word for what you need.
Overlay vs. Full Tear-Off — What's Actually Happening
When a contractor proposes an overlay (laying new shingles over the existing ones), they're saving themselves labor and disposal cost. Sometimes it's a legitimate option. Often it isn't.
Full tear-off is almost always the right call because:
- It lets the contractor inspect and repair the deck before installing new material. An overlay buries whatever problems exist underneath.
- Most areas have building codes limiting roofs to two layers. If you already have an overlay, you're at the limit and tear-off is required anyway.
- New shingles installed over old ones don't lie flat. It affects installation quality, warranty validity, and appearance.
- When the new roof eventually needs replacement, removing two layers costs significantly more than one.
If a contractor is pushing hard for overlay, ask them directly: what's the deck condition underneath? If they can't answer that without looking, they're guessing.
Material Options Worth Knowing About
The material decision matters more than most homeowners realize when they're focused on the total project cost.
- 3-tab asphalt shingles: The low-cost option. Flat profile, 20-25 year lifespan, no longer the standard on new construction. Fine for a budget-constrained replacement, but not what most contractors would recommend if you have a choice.
- Architectural (dimensional) shingles: The current standard. Thicker, layered profile, 30-50 year warranty, better wind resistance. The price difference over 3-tab is usually worth it over the roof's lifespan.
- Impact-resistant shingles: Class 4 rating resists hail damage and often qualifies for insurance premium discounts in Oklahoma City. Worth considering seriously if the area gets hail regularly.
- Metal roofing: 40-70 year lifespan, excellent in all weather, but significantly higher upfront cost. Makes the most sense on homes where the owner plans to stay long-term or where resale value justifies the premium.
Get the warranty documentation for whatever material is proposed. Manufacturer warranties and contractor workmanship warranties are separate — make sure you understand both.
What the Process Looks Like in Oklahoma City
A standard replacement runs roughly like this: contractor arrives and tears off existing shingles and underlayment down to the deck. They inspect the deck for rot, soft spots, or damaged sheathing and replace any sections that need it. New underlayment goes down first, then drip edge, then shingles from the bottom up. Flashing gets replaced or reset at all penetrations — chimney, vents, skylights. Ridge cap goes on last.
For a typical residential home in Oklahoma City, the physical work takes one to three days. The mess is real — a tear-off produces significant debris. Any contractor worth hiring will have a dumpster on-site and will leave the yard cleaner than they found it.
You don't need to leave your home during the work, but it is loud. Most families just plan to be somewhere else for the day.
Insurance and Storm-Triggered Replacements
If your replacement is being driven by storm or hail damage, insurance likely covers it. A few things that matter:
- Document everything before work starts. Photos and video of damage, date-stamped.
- Get a written contractor estimate before accepting any settlement number from your insurer. Adjusters are not always on your side.
- Ask your contractor whether they'll be present during the adjuster's inspection. Having someone who knows what they're looking at changes outcomes.
- Keep all receipts for any temporary protective work. Those costs can be included in the claim.
- Watch for the depreciation holdback — many policies pay actual cash value initially and release the remaining depreciation amount once work is completed and documented.
Frequently Asked Questions
How do I know if I need replacement vs. repair?
Age, scope of damage, and deck condition are the three factors. A roof over 20 years old with multiple failure points or a compromised deck is usually a replacement. A roof under 15 years with isolated damage is usually a repair. Have a contractor look at it -- the honest ones will tell you which it is.
How long does replacement take in Oklahoma City?
Physical work: one to three days for most homes. Scheduling lead time: a few weeks in normal conditions, longer after major storms. Material lead times can extend this further for specialty products.
Do I need to be home during the replacement?
No, but give the contractor access to a hose and a power outlet if they need it. Plan for noise -- a tear-off is loud and vibrates through the house. Most families just arrange to be elsewhere for the day.
