How to Remove Tar Paper From a Roof
Tar paper, or asphalt-saturated roofing felt, is commonly used as an underlayment or old roofing material. Removing tar paper can be messy and labor-intensive, but with the right approach, it can be done safely and effectively. This guide covers preparation, tools, step-by-step removal, cleanup, and disposal, focusing on practical methods for American homeowners tackling tar paper on a residential roof or attic space.
What Tar Paper Is And Why Removal May Be Needed
Tar paper serves as a moisture barrier beneath shingles or tiles. Over time, it can become brittle, moldy, or damaged by weather, making replacement necessary. Removal is often required when upgrading roofing, addressing leaks, or accessing underlying sheathing for repairs. Understanding the material helps in choosing the correct tools and safety steps to minimize damage and waste.
Safety Considerations And Preparation
Roof work carries fall hazards and exposure to old materials that may contain asbestos in very old homes. Always verify the age of the building and follow local regulations. Wear a hard hat, non-slip footwear, eye protection, gloves, and a dust mask or respirator if dust or mold is present. If asbestos-containing materials are suspected, consult a licensed professional before disturbance.
- Check weather: dry, calm days are ideal; avoid windy or wet conditions.
- Inspect the ladder and roof edge for stability; use a harness if needed.
- Test a small area first to gauge adhesion and ease of removal.
- Contain debris with tarps to protect landscaping and gutters.
Tools And Materials You’ll Need
Having the right tools reduces damage to the roof deck and speeds up the job. Gather these before starting:
- Heavy-duty putty knife or roofing scraper
- Wide pry bar and nail puller
- Oscillating multi-tool with a scraper blade (for stubborn tar)
- Roofing shovel or stiff-bristle brush
- Heat gun or heat source (optional for stubborn areas)
- Disposable plastic bags or contractor bags
- Tar paper disposal bags or a 6–8 mil plastic sheeting for waste
- Safety gear: gloves, eye protection, respirator or mask, knee pads
- Pressure washer or garden hose with spray nozzle (optional, for cleanup)
- Sealant and patch material for any damaged deck (if repairing is required)
Step-By-Step Removal Process
Approach the removal methodically to minimize damage to the roof deck and to keep work manageable. The following steps outline a practical sequence for most residential applications.

- Clear The Work Area: Move all loose shingles away from the work zone and cover nearby areas to protect paint, siding, and vegetation. Place tarps along gutters to catch debris.
- Loosen The Tar Paper: Use a wide putty knife or roofing scraper to lift the edge of the tar paper at a seam or rake. Work along the sheet, applying steady pressure to break the adhesive bond without gouging the roof deck.
- Remove The Material: Once an edge is lifted, slide the scraper under the tar paper and pull toward you, peeling off sections in manageable strips. For stubborn areas, a heat gun can soften the asphalt adhesive, easing removal. Be cautious to avoid scorching the deck.
- Tackle Stubborn Adhesive: In resistant spots, use an oscillating multi-tool with a scraper blade or a stiff-bristle brush to remove residual adhesive. Persist with shallow, even strokes to protect the decking.
- Inspect The Deck: After tar paper is removed, inspect the roof deck for damage, rot, or water intrusion. Mark any compromised sections for repair or replacement before re-roofing.
- Clean And Organize: Collect debris into disposal bags. Check gutters for tar fragments and rinse if necessary to prevent clogging.
Dealing With Residue And Surface Prep
Residual glue and asphalt can be challenging to remove. A clean surface ensures proper installation of new underlayment or roofing material. Use a scraper to lift adhesive residues and consider a light wash with water or a mild solvent recommended by roofing material manufacturers. Allow the deck to dry completely before applying new underlayment.
Disposal And Environmental Considerations
Tar paper and associated debris belong in accordance with local waste guidelines. Many municipalities require bulk waste collection rather than curbside recycling for roofing materials. Bundle tar paper in weather-resistant bags or dump them at an appropriate disposal facility. Do not dispose of tar paper into regular household trash in some jurisdictions, as asphalt can contaminate soil and water. If mold or hazardous materials are present, treat handling as hazardous waste and follow local regulations.
Repair If The Deck Is Damaged
Removal can reveal damaged roof decking or sheathing. If soft spots, rot, or mold are found, replace affected sections before proceeding with new underlayment or shingling. Cut and fit new plywood or OSB, securing with exterior-grade nails or screws. Seal edges with roof-grade sealant to prevent water infiltration. Consider consulting a pro for extensive structural repairs or if framing is compromised.
Choosing A Replacement Underlayment
After tar paper removal, select an appropriate underlayment. Options include synthetic roofing felt, rubberized asphalt underlayment, or peel-and-stick membranes. Synthetic felts offer improved tear resistance and longevity, while peel-and-stick membranes provide excellent water sealing. The choice depends on climate, roof slope, and the chosen roofing system. Follow manufacturer installation guidelines for best results.
Preventive Tips For The Next Roof
Proactive maintenance helps extend roof life and reduces future removal efforts. Regular inspections after major weather events, prompt repair of damaged shingles, and proper ventilation in the attic reduce moisture buildup. When replacing roofing, use a high-quality underlayment and ensure clean surfaces free from adhesive residues before installation. Scheduling professional inspections every few years can catch issues early and save costs over time.
Common Pitfalls To Avoid
Avoid rushing the removal process, which can cause decking damage or missed adhesive pockets. Do not mix incompatible solvents or cleaners that could degrade the roofing deck or new underlayment. Never work alone on a steep roof without proper fall protection. Finally, don’t ignore safety protocols around old insulation or mold-prone areas; address these concerns before proceeding.

For homeowners seeking more detailed guidance, consult manufacturer installation manuals for underlayment products, check local building codes on roofing material disposal, and review region-specific advisories on asbestos assessment. Local home improvement stores and roofing contractors can provide product recommendations tailored to climate and roof type.
