New construction roofing is a genuinely different job from a replacement. There is no tear-off, no disposal, and no unknown decking, which makes it cleaner and usually cheaper per square foot. What it adds instead is coordination, because the roof has to land in the right sequence between framing, mechanical penetrations, and the rest of the exterior.
It is also the one moment when you get to choose everything from scratch. Material grade, underlayment quality, ice and water shield placement, and above all ventilation design are all decided now, at a fraction of what they cost to change later. In Kennewick, where roof surfaces bake for months and wind loads are high, those decisions determine whether the roof gives you eighteen years or thirty.
If you are building with a production builder, the roof is usually already specified in the base package, often at the economical end. Ask what the allowance covers and what upgrading actually costs. If you are owner-building, adding an addition, or putting up a shop or ADU, you are contracting the roof directly, and comparing three bids applies exactly as it does on a replacement.
Decisions Worth Getting Right on a New Kennewick Roof
Design the ventilation, do not inherit it
Balanced intake at the eaves and exhaust at the ridge is the cheapest longevity upgrade available on a new build, and it is nearly free to specify now. Underventilated attics cook shingles from underneath in our summers and can void manufacturer warranties.
Upgrade the shingle grade at the start
The price difference between builder-grade and a quality architectural or impact-rated shingle is modest on a new build, and it commonly buys ten additional years. This is the highest-return decision on the entire roof.
Underlayment and ice and water shield
Synthetic underlayment outperforms felt, and ice and water shield at eaves, valleys, and penetrations is inexpensive insurance against our freeze and thaw cycles. Ask specifically what each bid includes rather than assuming.
Plan penetrations before the roof goes on
Every vent, flue, and future solar mount is a hole in your roof. Coordinating them before installation produces a cleaner, more reliable roof than adding them afterward. If solar is even a maybe, say so now.
Wind rating matters at the edges
Starter strips at eaves and rakes, plus proper nailing patterns, are what keep a roof attached in a Kennewick wind event. These are easy places for a low bid to save money, and they are the first things to fail.

My builder already includes the roof. Why get quotes?
Even when the roof is in the contract, knowing the market price for the material being installed tells you whether an upgrade is fairly priced. Builders typically offer a base shingle and charge for upgrades, and an independent quote is how you judge that number.
When in the build does roofing happen?
After framing and sheathing are complete and the structure is ready to be dried in, usually before siding and interior work. Getting the roof on promptly protects everything underneath it, so line up the contractor before you need them.
Is it cheaper to roof a new build than to replace?
Per square foot, yes, typically by a meaningful margin, because nobody has to remove and dispose of an old roof or repair surprise decking. The total can still be higher if the new home is larger or the roofline is more complex.
Can I use these quotes for a shop or ADU?
Yes. Select the property type on the quote form and contractors will bid accordingly. Shops and outbuildings with simple rooflines are often quoted with metal, which frequently makes the most sense on those structures.
Should I plan for solar now?
If solar is a possibility within the roof's lifetime, mention it while you are collecting bids. Planning mounting and penetrations before installation is far cleaner and cheaper than retrofitting into a finished roof.
