Our Structural Water Protection System
RV's have two structural rain water systems:
• The
Roof Rain Water System
• The
Sidewall Rain Water System
Both systems require seal integrity and runoff control to prevent long-term damage.

Most RV leak maintenance focuses on resealing surfaces.
Our approach focuses on managing how water moves across the structural and penetrations.
What 7 Years of Leak Investigations Revealed
After more than seven years of full-time RV leak investigations and repairs across hundreds of units, clear patterns emerge.
Most water intrusion did not occur randomly. It repeatedly appeared at the same locations.
These failures were not simply “bad sealant.”
They were often the result of design limitations, structural movement, improper sealant application and concentrated water runoff repeatedly flowing across vulnerable areas.
Over time, these field observations led us to develop a more systematic approach to RV water protection.
Instead of focusing only on just resealing, we began improving how the entire water management system works.
This work eventually evolved into the three-tier Structural Water Protection model used today.
Why Water Exposure Matters
Unlike residential construction, most RVs do not include roof overhangs or complete gutter systems.
Managing water movement is just as important as sealing seams, joints, trims, vents, windows, etc.
RVs also shake, rattle and flex during travel while experiencing temperature expansion and contraction, seal joints are constantly under stress.
Rainwater frequently flows directly across:
• Roof membrane to wall transitions & vents
• Slide openings
• Corner trim joints
• Windows and other wall penetrations (wholes cut in sidewalls for cargo storage, water inlets, venting, etc.)
Repeated runoff exposure concentrates large volumes of water at critical joints & openings. If a seal fails and the issue goes unnoticed, water intrusion can escalate quickly and cause significant structural damage.
Our Structural Water Protection System
Rather than addressing leaks one joint at a time, we developed a structured approach to managing both structural water systems.
Tier 1
Structural Leak Assessment™
Non-invasive pressure testing and structural evaluation of both water systems.
This process identifies:
• Active intrusion paths
• Sealant fatigue zones
• Moisture migration patterns
• Potential failure points
You receive documented image findings before any corrective work is recommended.
Tier 2
Leak Correction & Water Management
Confirmed intrusion points are corrected using targeted sealing methods.
NEW!
Where appropriate, we also apply Seal Integrity and Runoff Control designed to reduce runoff exposure at vulnerable areas.
These improvements may include:
• Roof flashing to redirect flow
• Modified trim geometry
• Gutter and downspout improvements
• Water Wicking Protection
Effective protection requires both seal integrity and runoff control, not sealant alone.
Tier 3
Delam Defense System™
NEW!
Designed specifically for laminated fiberglass and gel-coat RVs, this system focuses on protecting sidewall assemblies from moisture migration.
Delam Defense reinforces high-risk wall penetrations and trim joints to reduce long-term delamination risk.
Best suited for laminated RVs typically 1–15 years old, because delamination directly affects trade-in and resale value, preventing moisture intrusion is often far less expensive than repairing structural damage later.
Who This Is Best For?
Owners who prefer professional evaluation before investing in resealing or other work.
Typically:
• Laminated fiberglass travel trailers (Exterior Delamination Risk)
• Aluminum sided travel trailers (Compromised "S" joint seepage Risk)
• Units 1–15 years old
• Owners planning resale
• Owners preparing for major trips
• Owners who prefer documented professional work
Why Owners Choose Delam Defense
Even early-stage wall separation can significantly affect resale negotiations.
Delamination repairs
Structured sidewall protection strengthens confidence for:
• Future buyers
• Dealers evaluating trade-ins
• Long-term ownership planning
Typical Investment:
Most Delam Defense projects range between:
$899 – $2,500
depending on size, configuration & number of areas protected.
