Looking for flat & low-slope roofing in Castroville? Most people who land here want a quote for a flat or low-pitch section that shingle roofers keep declining. That's what this page is for.
Get a written quoteAerial measurement plus a five-minute history of the house beats a drive-by estimate in an area this varied. Real estate activity drives a lot of the roofing here — pre-listing inspections, buyer credits, and insurance-driven replacements right after closing. Roofs here tend to go longer between inspections, so damage from two or three storms ago is often still sitting there when someone finally looks.
On cost: priced per square like any roof but with a wider spread; TPO and modified bitumen are the common systems, and a silicone coating over a sound existing membrane is the lowest-cost path when it qualifies.

How it works
Not every residential roofer. Ask specifically whether the crew installs low-slope membrane or subs it. The tie-in between the flat section and the pitched roof is where leaks start.
TPO is a heat-welded single-ply, white, and reflective — good in Florida and Texas heat. Modified bitumen is torch- or self-adhered asphalt, more forgiving on complex details. Both are fine when installed right.
