Complete Roof Tear-Off and Replacement in Tulsa, OK
A tear off and replace roof project, also called complete roof replacement, involves removing every existing layer of roofing material down to the bare deck before installing a new system, rather than layering new shingles over what’s already there. In Tulsa, OK, decades of hailstorms, ice accumulation, and intense summer heat mean many roofs, especially in older neighborhoods like Brady Heights and Cherry Street, have already been reroofed once or twice using the overlay method, leaving hidden deck damage that only a full tear-off can reveal. Conrad’s Roofing has spent more than 10 years performing complete tear-off and replacement projects throughout Tulsa, with particular experience uncovering and repairing the deck damage that overlay roofing tends to hide in this region’s older housing stock.
Understanding Complete Roof Tear-Off and Replacement
A tear-off removes all existing roofing material, including old shingles, underlayment, and flashing, exposing the bare wood deck underneath. An overlay, by contrast, installs new shingles directly over the existing layer, a faster and cheaper approach that skips deck inspection entirely. Tulsa’s adopted building code, based on the International Residential Code, generally limits roofs to two layers of asphalt shingles before a full tear-off becomes mandatory, meaning many homes reroofed more than once are already required to go the complete replacement route on their next project.
Overlay roofing was common practice in Tulsa through the 1980s and 1990s as a lower-cost alternative to full replacement, particularly in older, established neighborhoods like Brady Heights and parts of Cherry Street where homes have gone through multiple reroofing cycles since original construction in the early 1900s. Today, complete tear-off has become the standard recommendation across Tulsa, both because of the two-layer code limit and because overlay roofing traps moisture and heat between layers, accelerating deterioration in ways that aren’t visible until the old layers come off.
An estimated significant share of Tulsa’s older homes, particularly those built before 1980, carry at least one prior overlay layer, and it’s common during tear-off to discover deck rot, previous storm damage, or ventilation problems that were simply covered over during an earlier reroofing rather than properly addressed.
Why Tulsa Homes Need Complete Tear-Off and Replacement
Tulsa’s storm history and reroofing practices combine to create deck and structural issues that only become visible once a roof is stripped down to bare wood.
Hidden Deck Damage Beneath Overlay Layers
The Mechanism: When shingles are installed over an existing layer rather than a tear-off, any water intrusion from cracked or lifted shingles beneath the top layer continues to reach the deck undetected. Over years, this trapped moisture causes the plywood or OSB decking to soften, delaminate, or rot, a process that accelerates in Tulsa’s humid summers when moisture has little opportunity to fully dry between rain events.
Symptoms: Soft or spongy spots felt underfoot during inspection, sagging between rafters, and in advanced cases, visible daylight or staining in the attic beneath the affected area.
Tulsa-Specific Factors: Homes in Brady Heights and older sections of Cherry Street, many carrying an overlay layer installed decades ago, show this deck damage most often, particularly on north-facing slopes where mature tree canopy slows drying after Tulsa’s frequent spring rain events.
Multiple-Layer Weight Load
The Mechanism: Each additional layer of asphalt shingles adds roughly 2 to 4 pounds per square foot to the roof structure. A home with two full layers plus new shingles installed as a third layer, technically a code violation but occasionally found on older properties, can add meaningful dead-load weight that older rafter framing wasn’t originally designed to carry, particularly under added snow or ice load during a Tulsa winter storm.
Symptoms: Visible sagging along the roofline or ridge, and in severe cases, structural stress visible from inside the attic.
Tulsa-Specific Factors: This is most common in historic homes in Maple Ridge and Brady Heights with original early 1900s rafter framing, which was sized for a single roofing layer rather than the multiple layers some of these homes have accumulated over a century of reroofing cycles.
Ice Storm and Hail Damage Compounded Across Layers
The Mechanism: The December 2007 ice storm, one of Oklahoma’s most damaging weather events, left significant ice accumulation and falling limb damage across Tulsa roofs. On homes reroofed with an overlay after that event, any deck damage from the storm itself was often covered rather than repaired, meaning the underlying problem has continued to worsen through every freeze-thaw cycle since.
Symptoms: Localized soft decking in the exact footprint of a fallen limb from a past storm, and water staining that reappears in the same spot after every significant rain.
Tulsa-Specific Factors: Neighborhoods with mature tree canopy, including Brookside and Maple Ridge, see this pattern most often, since falling limbs during the 2007 storm and subsequent hail and wind events caused concentrated impact damage that overlay roofing simply built over rather than resolved.
Ventilation Problems Trapped Beneath Overlay Roofing
The Mechanism: Proper attic ventilation depends on airflow paths at the ridge and soffit that can be partially blocked when a new layer is installed over an existing one without reassessing ventilation. In Tulsa’s summer heat, poor ventilation traps hot, moist air against the deck from underneath while trapped moisture works against it from above, a combination that shortens shingle life significantly.
Symptoms: Excessive attic heat in summer, higher-than-expected cooling costs, and premature granule loss or curling on the top shingle layer.
Tulsa-Specific Factors: South Tulsa homes with larger, more complex rooflines built from the 1980s onward sometimes have ventilation systems that were compromised during a prior overlay, a problem only correctable during a full tear-off when the deck and ventilation path are fully exposed.
Signs You Need Complete Tear-Off and Replacement
Exterior Signs
- Visible sagging along the roofline or ridge
- More than one existing layer of shingles (check at rake edges)
- Curling, cracking, or granule loss across large sections
- Multiple past repair patches that no longer match
Interior Signs
- Soft or spongy spots felt during an attic walk-through
- Water staining that reappears after every significant rain
- Excessive attic heat or high summer cooling costs
- Visible daylight through the roof deck
Structural and Code Signs
- A roof already at or beyond Tulsa’s two-layer code limit
- Deck damage discovered during a prior repair attempt
- Prior overlay installation with no record of deck inspection
Call for an inspection immediately if you notice sagging, soft decking, or recurring interior water stains, since these often indicate structural deck damage that has been building for years beneath an existing overlay layer.
How We Perform Complete Tear-Off and Replacement in Tulsa
Step 1: Roof Inspection – We assess the number of existing layers, general deck condition where visible, and ventilation setup before providing a scope of work. For a closer look at what this involves, see our roof inspection service. This takes 30-60 minutes.
Step 2: Complete Tear-Off – We remove every layer of existing roofing material down to the bare deck, regardless of how many layers are present. On older homes in Brady Heights and Cherry Street, this often reveals two or more layers accumulated over decades. This step typically takes 1-2 days depending on layer count and roof size.
Step 3: Deck Inspection and Repair – With the deck fully exposed, we identify and replace any rotted, delaminated, or storm-damaged plywood or OSB before installing anything new, since building a new roof over compromised decking defeats the purpose of a full tear-off.
Step 4: Ventilation Assessment – We evaluate and correct ridge and soffit ventilation paths, particularly important on homes where a prior overlay may have blocked proper airflow.
Step 5: Underlayment and Ice-and-Water Shield – We install synthetic underlayment across the full deck, with ice-and-water shield membrane at eaves and valleys given Tulsa’s freeze-thaw winter pattern.
Step 6: New Roof Installation – Shingles, metal panels, or the selected roofing material are installed to manufacturer specification on the fully repaired deck. This typically takes 1-3 days depending on material and roof complexity.
Step 7: Final Inspection and Cleanup – We inspect flashing, ridge vents, and seal points, then complete a full magnetic sweep and site cleanup before closing out the project.
What to Expect: Most complete tear-off and replacement projects in Tulsa take 3-7 days from start to finish, longer if significant deck repair is discovered once old layers are removed. We avoid scheduling tear-off when severe weather is in the forecast.
Complete Tear-Off Methods and Approaches
Single-Layer Tear-Off – The most common scenario, removing one existing layer of shingles down to the deck. Straightforward in scope but still requires full deck inspection.
Multi-Layer Tear-Off – Removing two or more accumulated layers, common in older Tulsa neighborhoods like Brady Heights, requiring additional labor time and more thorough deck assessment given the extended history of moisture exposure.
Tear-Off with Deck Replacement – Used when significant rot or storm damage is discovered, replacing affected plywood or OSB sections before new roofing goes down. Adds to project cost but is essential for a roof that will actually last its full rated lifespan.
Tear-Off with Ventilation Correction – Used when ridge or soffit airflow has been compromised by prior roofing work, correcting ventilation paths as part of the same project rather than as a separate repair later.
Maintaining Your New Roof After Tear-Off in Tulsa
- Schedule a professional inspection each spring and fall to catch developing issues before your next reroofing cycle
- Keep gutters clear before Tulsa’s spring storm season to prevent water backup at the eaves
- Trim tree limbs near the roofline in Brookside and Maple Ridge to reduce debris and impact damage
- Monitor attic temperature and humidity to confirm ventilation is performing as designed after the tear-off
- Address any new leaks or soft spots immediately rather than allowing another overlay-style cover-up
- Keep records of your tear-off and deck repair work for future reference and any insurance documentation

Frequently Asked Questions About Complete Roof Tear-Off and Replacement
Most projects take 3-7 days from start to finish, though multi-layer tear-offs or projects requiring deck repair can take longer depending on what’s found once old layers are removed.
Only if your roof currently has fewer than two layers, since Tulsa’s adopted building code generally limits roofs to two layers of asphalt shingles before a full tear-off is required.
Many older Tulsa homes have already been reroofed once using the overlay method, meaning they’re at or near the code-mandated layer limit, and overlay roofing tends to hide deck damage from past storms rather than resolving it.
Yes, a full inspection is the only reliable way to know how many layers exist and whether deck damage is present, since these factors determine whether a tear-off is required or simply recommended.
Any rotted or damaged plywood or OSB is replaced before new roofing is installed, which is priced separately once the scope of damage is confirmed with the old layers removed.
Yes, most homeowners remain in the home throughout the project. Expect noise during tear-off and installation, with precautions taken to protect landscaping and driveways.
