Rancho Cucamonga Roof Pros provides professional skylights & roof windows in Rancho Cucamonga, CA for residential and commercial properties across the western Inland Empire. The builders in these tracts set acrylic domes on site-built wood curbs and flashed them with a kit out of a box. Those units are now well past their design life, and the acrylic is usually crazed, yellowed and slightly out of shape.
They leak in two places and it is worth knowing which before anyone quotes you. Water at the corners of the shaft with a clean dome means the flashing failed, usually at the head, where no cricket was built and the course above dumps onto the curb. Water dripping from the middle of the dome on a cold morning is normally condensation on single-skin acrylic, a glazing and ventilation problem rather than a roof leak.
When we replace, we set a curb-mounted unit with laminated or insulated glass on a curb built to eight inches above the finished plane, wrap the curb in self-adhered membrane before the metal goes on, form a soldered or one-piece head cricket, and run a proper pan under the tile courses above rather than a strip of flashing on top of them. Deck-mounted units belong on composition, not under tile.
Sizing is worth an argument. Two small units in one room usually beat one large one for heat and glare here, and a tubular device serves a hallway or an interior bathroom better than any flat glazing would, at roughly a third of the cost and with no shaft to frame or drywall.
The timing point is the same one that runs through this whole site. Every skylight on a tile roof is surrounded by tile, and getting at it means lifting courses. If your felt is near the end of its range, replace the skylights during the relay. If you replace them now and relay in two years, you will pay twice to open the same six square feet.
We will also say when the right move is to close one up and patch the plane. A single-glazed dome over a room that is now air-conditioned through five months of the year is not always doing you a favour, and framing it out during a relay costs less than replacing it. That recommendation loses us the skylight sale and it is still the correct advice on perhaps one roof in six.
Our licensed and insured team brings the right materials and equipment to every job — self-adhered SBS modified underlayment meeting ASTM D1970, high-temperature synthetic underlayment rated above 240 degrees, thirty-pound organic felt, ASTM D226 Type II, counter-batten and drainable batten systems, stainless steel nose clips and wire-tie tile hooks, dry ridge vent systems in place of mortar bedding — and backs the work with a written workmanship warranty. We serve Rancho Cucamonga and nearby communities including Upland, Claremont, La Verne, San Dimas.

Materials, equipment and how we do skylights & roof windows
The difference between skylights & roof windows that lasts and skylights & roof windows that gets redone in three years is almost always preparation and materials, not the finish you see on day one. We work with self-adhered SBS modified underlayment meeting ASTM D1970, high-temperature synthetic underlayment rated above 240 degrees, thirty-pound organic felt, ASTM D226 Type II, counter-batten and drainable batten systems, spec them to the job instead of to the invoice, and write the material grades into the free estimate so you know exactly what you are buying.
Every Rancho Cucamonga job runs the same way: site walk and measurements, written scope and fixed price, protection of the surrounding area, then the work itself with a daily clean-up. Years of roofing work in the western Inland Empire means we have already met whatever your property is going to throw at us — awkward access, older construction, an HOA with opinions.
