OCRV Center repairs roof edges, residential window frames, skirting damage and long term leaks for West Covina owners in Yorba Linda. ## Common damage - Roof edge and drip rail damage picked up during transport to or from a site - Residential style window frames leaking where the flange meets the sidewall - Sliding glass patio door frames racking after the trailer settles on its blocks - Sealant that was never reapplied after the original bead reached the end of its life - Skirting panels cracked, warped or torn away by wind at the site - Corrosion at frame crossmembers where skirting trapped moisture underneath - Shingled or residential style roof edge lifting at the eave - Sagging floors over blocking that was set unevenly at the site - Deck and porch attachments that were fastened into the sidewall rather than the frame - Awning arms and rails torn loose after being left deployed through a wind event ## A destination trailer barely moves, and that is the problem A destination trailer is designed to be towed to a site and left there. Many of them make one trip from the dealer, one trip when the owner changes parks and one trip at the end of their life. Everything else that happens to them happens while they are stationary. That inverts the normal maintenance conversation. A travel trailer owner inspects the roof because they see it hitched up several times a season. A destination trailer owner walks past the same unit for six years without ever getting on the roof. The construction reflects the intended use. These units carry residential windows and doors, a residential feel interior, sometimes a shingled or membrane roof with a real pitch, larger appliances, and in many cases a loft. What they do not carry is the reinforcement a frequently towed trailer gets, because it was not expected to be towed frequently. That is a rational engineering decision and it becomes an owner problem the day the trailer has to move. For West Covina owners, most of these live at a park up in the mountains, out at the river, or down toward the coast, and they come to us either after a move went badly or after a leak that has been developing quietly for years finally reached something visible. Both are common. Both are repairable. Neither is a small job once the water has been in the structure for multiple seasons. - Designed to be sited, not towed, so reinforcement is minimal - Residential windows, doors and roofing behave differently from RV components - Roof inspection almost never happens because the unit never gets hitched - Damage is either transport related or the result of years of slow leaking ## Transport damage and the roof edge that takes it The two or three tows a destination trailer sees in its life are the most violent thing that ever happens to it, and the roof edge takes the worst of it. These units are tall. Branches at a park entrance, a low limb on a park road, an overhang at a gate, a covered fuel canopy: all of them contact the roof edge first because it is the highest and widest point. The result is a torn drip rail, a lifted roof membrane at the edge, a crushed corner molding and often a section of the eave pulled loose along a run of several feet. The second transport related damage pattern is the front and the sides taking road debris and wind loading they were never set up for. A unit that has sat for six years has sealant that is well past its service life, hardware that has seized and window frames that have not moved. Tow that down a highway and things that were quietly holding on come loose. Owners are frequently surprised to find a window frame weeping after a move when it was dry for years. Repair of a torn roof edge is a real job and it is worth doing correctly. The membrane or roofing gets opened back to sound material, the damaged decking and edge framing gets cut out and replaced, new edge trim and drip rail is installed, and the seam is rebedded and sealed with the correct product for the roof type. Where the eave framing has pulled, the framing gets repaired rather than the trim simply being screwed back down over a gap. Trim over damaged framing is how a small transport injury turns into a rotted eave. ## Residential windows, patio doors and frames on a moving building Destination trailers use residential or residential style windows and sliding patio doors because they feel better to live with. Those units are engineered to sit in a wall that does not move. A trailer, even a stationary one, moves: it settles on its blocking, it expands and contracts with temperature, and it flexes any time it is towed. The mismatch produces a specific set of failures. Sliding glass patio doors are the most sensitive component on the trailer. When the unit settles unevenly on its blocks, the opening racks by a fraction of an inch and the door stops rolling smoothly, then stops latching, then leaves a gap at the top or bottom of the meeting stile. Owners try to fix it by adjusting the rollers, which works once and then stops working. The actual problem is the opening, and it needs the trailer releveled and the opening squared before the door will behave. Window flanges are the other issue. A residential style window is set into the sidewall with a flange and sealed at that flange. When the sealant reaches the end of its life, water gets behind the flange and into the wall. Because these units use conventional wall assemblies in many cases, that water can travel a long way before it shows. We repair by removing the window, cutting back wet material, repairing framing and sheathing, reinstalling with a correct flashing and sealing sequence and refinishing the exterior. Reinstalling a window over damp sheathing is a repair with a very short life. - Residential windows and doors expect a wall that does not move - A racked patio door opening is a leveling problem, not a roller problem - Window flange sealant failure lets water into the wall assembly - Windows get reset with a proper flashing sequence, not just fresh caulk ## Skirting, blocking and the underside of a trailer that never moves Skirting makes a destination trailer look finished, keeps the underside warmer and keeps animals out. It also creates an enclosed, poorly ventilated space directly under a steel frame, and if that space does not drain and breathe, it becomes the reason the crossmembers corrode. We regularly find serious frame corrosion on units that look immaculate from the outside because the skirting has been trapping moisture against the underbelly for years. The skirting itself takes wind damage. Panels crack, warp in the sun, pull off their retaining tracks and tear away in a gust. That is straightforward to repair or replace, and it is the right moment to look at what is behind it. When we take skirting off for a repair we photograph the underside for the owner, because most have never seen it. Blocking is the other stationary issue. A unit set on blocking that has settled unevenly puts a twist into the frame that stays there for years, and the frame slowly accepts it. Floors sag between supports. Interior doors bind. The patio door racks. Correcting that means relevelling on adequate blocking with proper support under the frame at the right points, then addressing whatever the twist did while it was in place. Deck and porch structures attached to the trailer add another variable, because a deck fastened into the sidewall rather than into the frame will pull on that wall every time the deck moves. ## Set and forget sealant and the leaks it produces Every sealed joint on a destination trailer has a service life, and in Southern California the sun sets that life short. A unit that has been sited for six or eight years without a single reseal has roof penetrations, roof to wall seams, window flanges and corner trim all past the end of their intended life at the same time. When one finally lets go, the others are usually not far behind, which is why the honest answer to a single stain on the ceiling is often an inspection of everything rather than a spot repair. The damage pattern in a stationary unit is worse than in a towed one for a simple reason: time. A travel trailer leak gets noticed on the next trip. A destination trailer leak drips into the same spot for two seasons. By the time a stain reaches an interior finish, the substrate, the framing and often the flooring have been wet for a very long time. Owners are understandably frustrated to hear that a small stain represents a large repair, and it is better to say that at the estimate than to discover it after teardown. The prevention conversation is simple and worth having. Get on the roof, or have someone do it, at least once a year. Look at every penetration, the roof to wall seam, the eave and the corner trim. Look at the window flanges from outside. Look at the door thresholds. A destination trailer that gets an annual inspection stays out of the body shop almost indefinitely. One that does not eventually arrives with a structural job. - All the sealed joints on a sited unit age out at roughly the same time - Stationary leaks run into the same spot for seasons before they show - A single ceiling stain frequently represents years of accumulated damage - An annual roof and flange inspection is the entire prevention program ## Moving a destination trailer between West Covina and Yorba Linda Getting a destination trailer to the shop is a logistics question before it is a repair question. These units are heavy, tall and long, and many owners do not have a vehicle capable of towing them. Arranging transport is the owner's responsibility, and it is worth using a transporter who moves park models and destination units regularly rather than a general hauler, because height clearance and load securement on these is specific. The shop is at 23281 La Palma Ave in Yorba Linda, about 22 miles from West Covina and 30 to 45 minutes by car. If the unit is being brought from a park in the mountains or out at the river, plan the route with your transporter for height clearance. Before it moves, secure everything inside, remove anything on the roof, take the skirting off or secure it, and photograph the unit from all four corners so there is a documented starting condition. Transport damage is much easier to sort out with a before photograph. For owners weighing whether a repair is worth doing, bring photographs and let the estimator look at them before the unit moves. We can tell you a great deal from clear pictures of the roof edge, the interior stain, the window flanges and the underside. If the answer is that the unit should come in, we will say so. All work is performed in the building at Yorba Linda and we do not offer mobile service.

The eave is the highest and widest point, so it makes contact first, and the damage is typically a torn drip rail, membrane lifted along the edge, crushed corner molding and pulled eave framing. Repair opens the roofing back to sound material, replaces damaged decking and edge framing, installs new drip rail and trim and rebeds the seam with the correct product for that roof type. Screwing the trim back down over damaged framing is what turns a transport injury into a rotted eave. ### My sliding patio door will not latch and I have already adjusted the rollers. Now what? The rollers are not the problem. When a sited unit settles unevenly on its blocking, the door opening racks slightly, and a residential sliding door has almost no tolerance for that. Adjusting rollers compensates once and then runs out of adjustment. The fix is to relevel the unit on adequate blocking with support at the correct frame points, square the opening, and then reset the door. If the racking has been in place for years, the surrounding wall and the door frame itself may need attention as well. ### Is skirting causing the rust I found under my trailer? Very possibly. Skirting creates an enclosed space under a steel frame, and if that space does not drain and ventilate, moisture sits against the crossmembers and the underbelly for years. We find significant corrosion on units that look perfect above the skirt line for exactly this reason. When we pull skirting for a repair we photograph the underside so you can see the condition. Repair covers cleaning, treating and where needed sectioning corroded members, plus improving drainage and ventilation so it does not recur. ### One ceiling stain appeared this winter. Why does the estimate cover so much more than that? Because a stationary unit leaks into the same place for a long time before anything shows. On a towed trailer you would notice on the next trip. On a sited unit the water has usually been arriving at that spot for two or more seasons, so the substrate, the framing and often the flooring below have been wet the whole time. We open a small area to establish how far it has traveled before writing the full scope, and we show you what we find. It is better to know at the estimate than after teardown. ### Can you work on the deck and porch attached to my destination trailer? We work on what attaches to the trailer, and that attachment is frequently the actual problem. Decks fastened into the sidewall rather than into the frame apply load to a laminated wall every time the deck moves or someone walks on it, which tears fasteners out and opens the wall to water. We repair the wall, install proper structure and reattach the deck through a connection that loads the frame. Whether we rebuild the freestanding deck itself is a conversation for the estimate. --- OCRV Center, 23281 La Palma Ave, Yorba Linda, CA 92887. Phone (949) 799-3387.
