Cheapest time for flat roof replacement in Kensington
Roofers are slammed the moment warm weather returns, especially after storms. Get on their books in the off-season for a spring job and you're negotiating with an empty calendar, not a waiting list.
Why flat roof replacement quotes vary — and how to compare them fairly
Two bids for the “same” job can differ by thousands. Usually it's scope, not greed — here's what moves the number and how to get an apples-to-apples comparison.
Why a quote looks high (or low)
- One bid is a full tear-off; another lays new shingles over the old roof — cheaper now, costlier later.
- A storm-chaser's lowball often skips flashing, ice-and-water shield or a real warranty.
- Shingle tier (3-tab vs. architectural vs. premium) changes both material and labor.
Get an apples-to-apples bid
- Confirm underlayment, ice-and-water shield, flashing and ventilation are included.
- Ask how deck/sheathing repairs are priced if rot is found.
- Specify tear-off vs. overlay so all bids match.
- Verify the contractor is licensed, insured and local, with recent references.

Where does a smart roofing budget go in 2026?
Tear-off vs. overlay, shingle tier and what's hidden under the deck decide the real number. Our editors on the trade-offs.
The value case
Architectural shingles hit the sweet spot — far more durable than 3-tab for a modest premium, and far cheaper than metal or tile. For most homes they're the right default.
The risk case
Budget for the unknown: rotten decking found at tear-off is the most common surprise. Get the per-sheet repair rate in writing up front so a "cheap" bid doesn't balloon mid-job.
The do-it-right case
Pay for a full tear-off and quality underlayment, flashing and ventilation. An overlay saves money today but traps heat, voids some warranties and costs more at the next replacement.
The two things that actually protect a roofing budget are a real tear-off and a written rate for any deck repairs found along the way. The cheapest post-storm bid usually isn't the cheapest roof, long-term.
