How To Replace A Mobile Home Roof: Step-by-Step Guide

Step 1: Remove the Old Roof

Start by removing the existing roofing material. If the roof is covered with shingles, use a roofing shovel to lift and remove them. For metal roofs, unscrew the panels and lift them off. Be careful not to damage the underlying structure.

Step 2: Inspect the Roof Deck

Once the old roofing material is removed, inspect the roof deck for any damage. Look for signs of rot, mold, or structural issues. Replace any damaged sections of the roof deck with new plywood.

Step 3: Install Underlayment

Lay a high-quality roofing underlayment over the roof deck. This acts as a moisture barrier and provides a smooth surface for the new roofing material. Secure the underlayment with roofing nails or staples, ensuring it is flat and free of wrinkles.

Step 4: Install Flashing

Install metal flashing around the edges of the roof, as well as around any vents, skylights, or chimneys. Flashing helps prevent water from seeping into the joints and seams of the roof.

Step 5: Lay Down Roofing Material

Depending on the material you’ve chosen, the installation process will vary:

  • Metal Roofing: Start at the bottom edge of the roof and work your way up, overlapping each panel. Secure the panels with roofing screws, ensuring they are tightly fastened.
  • Asphalt Shingles: Begin at the bottom row, laying shingles and overlapping each row as you work your way up. Nail the shingles in place, making sure they are properly aligned.
  • Rubber Membrane: Roll out the rubber membrane over the roof, securing it with adhesive or roofing nails. Ensure the membrane is smooth and free of wrinkles.

Step 6: Seal and Secure

Once the roofing material is in place, apply roofing sealant to all seams, joints, and around any penetrations (such as vents or chimneys). This helps prevent water infiltration and ensures a watertight seal.

Step 7: Install Ridge Cap

Install a ridge cap along the peak of the roof to cover the seams where the roofing material meets. Secure the ridge cap with roofing nails or screws, ensuring it is properly aligned and sealed.

Maintenance Tips for Your New Roof

Regular maintenance is crucial to extend the lifespan of your new mobile home roof and prevent future issues:

  1. Inspect Regularly: Check the roof at least twice a year for signs of damage, leaks, or wear and tear.
  2. Clean Debris: Remove leaves, branches, and other debris from the roof surface to prevent water buildup and damage.
  3. Repair Promptly: Address any issues, such as loose shingles or damaged flashing, as soon as they are noticed to prevent further damage.
