Tear Off and Install a Flat Roof

1. Assessing the Roof Condition
Before starting a flat roof tear-off, a thorough inspection is necessary to determine the extent of damage, leaks, or structural weaknesses. Key aspects to check include:
- Ponding water: Flat roofs often accumulate water due to poor drainage.
- Blisters and cracks: These indicate aging and potential leaks.
- Insulation condition: Damaged insulation can lead to heat loss and moisture issues.
Pro Tip: If your roof has extensive water damage or multiple leaks, a full tear-off is the best solution.
2. Preparing for Tear-Off
Preparation ensures a smooth and safe removal of the old roof. Steps include:
- Obtaining necessary permits as required by Denver building codes.
- Setting up safety measures like harnesses and guardrails.
- Protecting surrounding areas from falling debris.
- Arranging for proper waste disposal, such as using a dumpster.
3. Tearing Off the Old Roof
The tear-off process involves:
- Removing surface materials: This includes gravel, membranes, or old coatings.
- Lifting and stripping away layers: Using roofing shovels or cutters, old roofing materials are removed.
- Clearing debris: Ensuring a clean work area to prevent hazards.
Note: Some older flat roofs may contain asbestos. If so, professional removal is required.
4. Inspecting the Roof Deck
Once the old material is removed, the roof deck must be inspected for:
- Rotting or damaged wood
- Structural integrity issues
- Moisture damage
If any sections of the deck are compromised, they must be replaced before proceeding with the new installation.
5. Choosing the Right Flat Roofing Material
The choice of roofing material depends on budget, climate, and durability needs. Common options include:
- TPO (Thermoplastic Olefin) – Energy-efficient and UV-resistant.
- EPDM (Ethylene Propylene Diene Monomer) – Durable and flexible.
- Modified Bitumen – Asphalt-based and highly weather-resistant.
- PVC (Polyvinyl Chloride) – Strong, chemical-resistant, and long-lasting.
Pro Tip: TPO is a great choice for Denver’s climate due to its energy efficiency and durability.
6. Installing the New Roofing System
The installation process includes:
- Laying a vapor barrier to prevent moisture issues.
- Installing insulation for better energy efficiency.
- Applying the chosen roofing material using adhesives, fasteners, or heat welding.
- Securing seams and edges to prevent leaks.
7. Sealing and Waterproofing
Proper sealing ensures long-lasting protection from water infiltration. Steps include:
- Using seam tape or heat welding (for TPO and PVC roofs).
- Applying flashing around vents, pipes, and edges.
- Coating with reflective sealants to extend the roof’s lifespan.
8. Final Inspections and Cleanup
Once the roof is installed, a thorough inspection ensures everything is secure and meets building codes. Steps include:
- Checking for proper drainage and slope.
- Inspecting all seams, edges, and flashing.
- Cleaning up the worksite and disposing of waste materials responsibly.
9. Maintenance Tips for Longevity
To keep your flat roof in top shape:
- Schedule annual inspections.
- Keep drains and gutters clear.
- Address small leaks immediately.
- Apply reflective coatings to reduce UV damage.
