Roof and Seal Inspection: Cost, Hours and Process in Hacienda Heights

Every coach has somewhere between fourteen and thirty roof penetrations depending on the floorplan: vents, fans, skylights, air conditioner shrouds, refrigerator and water heater vents, plumbing stacks, antennas, solar mounts, ladder brackets, rack feet, and the front and rear cap transitions. Each one is a sealant joint with its own age and its own condition.

The inspection walks all of them and records each individually rather than reporting a single verdict on the roof. Alongside that, the deck is read for moisture on a grid, with a dry area on the same coach used as the baseline because absolute meter numbers vary by material and by ambient humidity.

What you receive is a mapped report: a diagram with each penetration numbered, its sealant condition, any elevated moisture area outlined, photographs, and a priority order. That report is what lets you make a decision instead of taking somebody's word for it, and it is what an adjuster or a buyer will actually read.

• Every penetration numbered, photographed and condition graded individually
• Seam and cap transition condition recorded separately from penetrations
• Deck moisture read on a grid against a dry baseline on the same coach
• Slide topper rails and awning rail sidewall transitions included
• Wrong product and prior repair history flagged, including silicone
• Priority order: now, this season, watch

Sealant manufacturers write their service life expectations for a national average. The San Gabriel Valley is not the national average. The UV load here chalks a self levelling sealant in three to four years rather than the six to eight assumed, and the rainfall pattern is the second half of the problem: a dry summer bakes the sealant brittle and then several inches of rain arrive in a week.

That combination is why we recommend a survey every six months on a coach stored uncovered and at minimum before every rainy season. It is also why an owner who resealed four years ago and assumes they are fine frequently is not.

The asymmetry is what makes the interval worth keeping. A sealant renewal caught in time is a low four figure job at most. The same failure found after water has been in the decking for two seasons is a five figure job, because the membrane comes off and the decking and framing come out.

This page is deliberately an inspection only. We survey, we read moisture, we photograph, we report. If the report says the sealant is due, the reseal is a separate quoted job under roof work. If the report says moisture has reached the deck, that is membrane and decking work and it is quoted there.

Keeping them separate is the point. An inspection that is bundled into a reseal gives you no way to tell whether the reseal was needed, and it removes any reason for the shop to tell you the roof is fine. This way the inspection stands on its own and so does the recommendation.

It also means you can bring the report elsewhere. We would rather do the work, obviously. We would rather more that Hacienda Heights owners get a survey at all than skip it because they assume it is a sales call.
