Step-by-Step Roof Replacement Process
This is a simplified overview. Always refer to the manufacturer’s instructions for your specific roofing material.
### Step 1: Removing the Old Roof
- Safety First: Ensure the travel trailer is parked on a level surface and the wheels are chocked. Wear your safety harness and use caution when working on the roof.
- Remove Accessories: Detach all vents, skylights, air conditioners, and other accessories from the roof. Carefully disconnect any wiring.
- Cut and Remove the Old Roofing: Using a utility knife, carefully cut the old roofing material into manageable sections. Peel it away from the substrate. This can be a messy and time-consuming process.
- Scrape Away Old Sealant: Thoroughly scrape away all old sealant and adhesive residue from the roof surface. This is crucial for ensuring proper adhesion of the new roofing material.
### Step 2: Inspecting and Repairing the Substrate
- Check for Damage: Carefully inspect the roof substrate (usually plywood or OSB) for any signs of water damage, rot, or soft spots.
- Replace Damaged Wood: If you find any damaged wood, cut it out and replace it with new plywood or OSB of the same thickness. Secure the new wood with screws or nails.
- Clean and Prepare the Surface: Clean the entire roof surface thoroughly with a roof cleaner to remove any remaining dirt, debris, or residue. Allow the surface to dry completely.
### Step 3: Applying the New Roofing Material
- Dry Fit: Before applying any adhesive, unroll the new roofing material and dry fit it to the roof to ensure a proper fit. Trim any excess material.
- Apply Adhesive: Following the manufacturer’s instructions, apply adhesive to the roof substrate. Work in small sections to prevent the adhesive from drying out before the roofing material is applied.
- Roll Out the Roofing Material: Carefully roll out the roofing material onto the adhesive, smoothing it out as you go to eliminate any air bubbles or wrinkles. Use a roller to ensure proper adhesion.
- Seal the Seams: Apply seam tape to all seams of the roofing material to create a watertight seal. Use a roller to press the tape firmly into place.
- Trim the Edges: Trim any excess roofing material from the edges of the roof.
### Step 4: Reinstalling Accessories and Sealing
- Reinstall Accessories: Reinstall all vents, skylights, air conditioners, and other accessories, ensuring they are properly sealed with RV sealant.
- Apply Sealant: Apply a generous bead of self-leveling sealant around the base of all accessories and along all edges of the roofing material. Use non-sag sealant for vertical surfaces.
- Inspect and Finalize: Carefully inspect the entire roof for any gaps or imperfections and apply sealant as needed. Allow the sealant to cure completely before exposing the roof to water.
