Armour Spray Foam | Insulation Installation & Roofing in Mandeville, LA 70471

Spray foam insulation is applied directly to the underside of your roof deck, creating a monolithic, airtight barrier. For roof valleys—a common leak point during our heavy rains—this seal prevents warm, moist indoor air from reaching the cold roof surface and condensing. It also adds structural strength and seals around nails and penetrations, blocking the primary paths for water intrusion and protecting your home from the inside out.

If your ridge cap is damaged or leaking, moisture has likely already compromised your existing attic insulation, especially traditional materials like fiberglass batts. Wet insulation loses its R-value, promotes mold growth, and can damage your roof deck. Our insulation removal service safely extracts the damaged material, allowing for a full assessment of the roof deck. We then install new spray foam, which adheres directly to the deck, providing superior protection and preventing future moisture issues from similar damage.

For our local climate, spray foam offers key advantages. It provides a much higher R-value per inch and acts as an air and moisture barrier. This combats both energy loss and the humidity that leads to condensation in your attic—a common contributor to roof deck rot and mold. By sealing the roof deck, it also helps prevent the wind-driven rain we experience from pushing moisture into your home through minor roof imperfections, offering a more resilient and energy-efficient solution.
