Mentor Windows provides professional bay and bow windows in Mentor, OH for residential and commercial properties across Lake County's Erie shore. A bay is the only window on a house that is also a piece of structure and a piece of roof. It leaves the wall plane, carries its own weight on a cantilever, and grows a small roof that has to be flashed like any other roof.
That change of geometry also changes the wind. The flat-wall pressures in the code tables assume a window sitting in a wall. A projecting assembly presents angled faces to the flow and picks up loads on its underside and its roof that those tables were never meant to describe. On a sheltered street this is academic. On the shoreline it is not.
Inside the 600-foot Exposure D band, a bay is the one assembly on a house where we will ask for a manufacturer's engineering rather than reading a table. Head and seat board spans, the cable or knee-brace support, the fastening back into the rim joist: all of it should be sized against the actual site pressure, and the supplier can do that if asked.
The roof over the bay is where these fail, and it fails the same way every time. Ohio requires ice barrier underlayment statewide, and a bay roof is a short, low-slope run terminating against a wall — precisely the geometry that backs water up under shingles in a January thaw. Membrane over the whole deck, a proper kickout at the wall, and step flashing woven into the siding.
The seat cavity is the second failure point and nobody looks at it. Below the seat board is a small floor cantilevered over outside air, and in a Lake County winter it needs insulation and an air seal as serious as a rim joist. Get this wrong and you have a permanently cold seat, condensation on the glass, and mold in the corner nobody can see.
On configuration, an angled bay of three units carries load better than a wide gentle bow of five, because the joints between lites are steeper and the projection is shorter. If you want the sweep of a bow and you are near the water, the sensible compromise is a shallower projection with the same number of lites.
The most common honest answer here is that the existing bay does not need replacing at all. Very often the units are sound and what has failed is the roof, the flashing or the seat insulation. That is a much smaller job, and we will price it that way when it is what the house needs.
When a bay does come out we quote the whole assembly: units, head and seat construction, support method, roofing and flashing, insulation and interior trim. A bay quoted as windows alone is a quote that has left out the parts that actually fail, and it is the reason so many bays get done twice.
Our licensed and insured team brings the right materials and equipment to every job — Exposure D taken 600 feet in from the edge of open water, component and cladding pressure read out of Table 301.2(2), height and exposure coefficient of 1.47 on a one-story wall, performance class LC specified in place of class R, water penetration test pressure of 3.75 pounds per square foot, steel stiffener slid into a vinyl meeting rail — and backs the work with a written workmanship warranty. We serve Mentor and nearby communities including Mentor-on-the-Lake, Eastlake, Willowick, Willoughby.

Materials, equipment and how we do bay and bow windows
The difference between bay and bow windows that lasts and bay and bow windows that gets redone in three years is almost always preparation and materials, not the finish you see on day one. We work with Exposure D taken 600 feet in from the edge of open water, component and cladding pressure read out of Table 301.2(2), height and exposure coefficient of 1.47 on a one-story wall, performance class LC specified in place of class R, 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 Mentor 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 window work in Lake County's Erie shore means we have already met whatever your property is going to throw at us — awkward access, older construction, an HOA with opinions.

Why Mentor Chooses Mentor Windows
- ✓We settle the wind exposure category before opening a catalog. Six blocks decides whether your house needs a residential-class window or a light-commercial one, and no product page will tell you that.
- ✓Grades are quoted at a size. A performance grade with no size attached is a number you cannot use, so every line on our sheet carries both, along with the wall zone it came from.
- ✓We buy from several manufacturers rather than one line. A bluff-top house at the Headlands and a ranch two miles inland do not want the same window, and a single-brand quote pretends otherwise.
- ✓Sill pans go under every door and low sill as standard rather than as an upgrade line. It costs very little during installation and it cannot be retrofitted afterwards without pulling the unit back out.
