Naperville Premium Roofing provides professional roof ventilation in Naperville, IL for residential and commercial properties across the DuPage and Will county suburbs. Ventilation is the part of a Naperville roof that nobody inspects, almost nobody itemises, and most people get wrong by installing the exhaust and skipping the intake. It is also comfortably the cheapest thing on this list to put right.
The rule is balance, not quantity. Continuous soffit intake has to at least match the ridge exhaust, and the figure that matters is net free area in square inches, not the length of vent you can see from the driveway. Add a ridge vent to a house whose soffits are packed solid with blown insulation and you have built a device that draws conditioned air out of your living space through the ceiling.
Around here the symptom shows up in February. Frost forms on the underside of the sheathing overnight, melts during a mild afternoon, and drips onto the insulation below. Homeowners report it as a roof leak in dry weather, which is the tell. The roof is not leaking at all; the attic is manufacturing its own water, because warm and humid indoor air is reaching the cold deck and has nowhere else to go.
So we start inside. Baffles at every rafter bay to keep insulation clear of the soffit, air sealing at top plates, recessed light housings and the attic hatch, bath and kitchen fans ducted to the outside rather than into the space, and only then a continuous baffled ridge vent, sized against the intake figure we have just confirmed and measured rather than against the length of the ridge.
We argue against powered attic fans on almost every house we see. They are loud, they fail, they compete directly with the ridge vent, and on a leaky ceiling plane they will happily pull heated air out of the house in January and cooled air out in July. Mixing a powered fan with continuous ridge exhaust short-circuits both of them.
Because none of this is permitted or inspected, we put both figures into the written scope: net free area of intake, net free area of exhaust, and the ratio they produce. It is one line, it takes a minute to check against the manufacturer's data, and it is the clearest single signal of whether whoever roofed your house was thinking about the assembly or only about the shingles.
Our licensed and insured team brings the right materials and equipment to every job — ASTM D3462 fiberglass-mat laminated shingles, ASTM D7158 wind classification stated per slope, half-inch CDX sheathing swapped at an agreed per-sheet price, self-adhered ice barrier carried past the inside face of the exterior wall, ring-shank fasteners driven in the manufacturer's nailing zone, 24-gauge snap-lock standing seam over high-temperature underlayment — and backs the work with a written workmanship warranty. We serve Naperville and nearby communities including Lisle, Woodridge, Warrenville, Wheaton.

Materials, equipment and how we do roof ventilation
The difference between roof ventilation that lasts and roof ventilation that gets redone in three years is almost always preparation and materials, not the finish you see on day one. We work with ASTM D3462 fiberglass-mat laminated shingles, ASTM D7158 wind classification stated per slope, half-inch CDX sheathing swapped at an agreed per-sheet price, self-adhered ice barrier carried past the inside face of the exterior wall, 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 Naperville 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 DuPage and Will county suburbs means we have already met whatever your property is going to throw at us — awkward access, older construction, an HOA with opinions.

Why Naperville Chooses Naperville Premium Roofing
- ✓We state in writing whether your job triggers a Naperville permit, because an asphalt re-cover over sound sheathing does not, and that means no inspector will ever see it.
- ✓A per-sheet price for half-inch CDX sheathing is agreed and signed before tear-off morning, so "we found rot" is a number you already approved rather than a negotiation on a ladder.
- ✓Our Illinois roofing license number is on the bid, the contract and the truck, and you can check it against the state register before you call anyone.
- ✓Arbitration and jury-waiver clauses are pointed out and signed separately, the way Illinois law requires, or they do not bind you at all.
