Licensed. Local. Accountable.
Your roof is the first line of defense for everything underneath it — your family, your finishes, your foundation. We approach every replacement, repair, and remodel with that responsibility: permits pulled, materials specified in writing, and walkthroughs that leave you confident instead of guessing.
We started J Castillo Construction on a simple idea — that a roofing contractor should talk to homeowners the way we'd want to be talked to. No inflated urgency, no vague scopes, no disappearing after the check clears. A decade later, that approach is still why Herndon, VA calls us back for the next project, and refers us to their neighbors.

How we work
Four steps. No surprises.
01
Inspect, honestly
We climb the roof, not just the estimate. You get photos, plain-language findings, and options — including when repair beats replacement.
02
Scope it in writing
Materials, timeline, and price are locked in before a single shingle moves. No surprise change orders once we start.
03
Build it right
Licensed crews handle tear-off, decking, and installation to code — with daily cleanup so your property stays livable.
04
Walk it together
We finish with a final walkthrough, warranty paperwork, and a straight answer to whatever you ask next.
