Roof Replacement in Aurora, IL

What a Full Replacement Actually Includes

Here is the sequence, in order, because an itemised estimate is only useful if you know what the items are.

Everything comes off first, down to bare deck. That is when we find out what we are really dealing with, and it is why every honest estimate carries a decking allowance rather than a flat price: nobody can see through two layers of shingle. We replace soft sheets at an agreed per-sheet rate that is on your estimate before we start, so there is no conversation on the day about a number you have not already seen.

Then ice and water shield along the eaves. Aurora requires it from the fascia to at least 24 inches inside the exterior wall line, or 36 inches measured up the slope from the eave edge, whichever reaches further. We run it in valleys and around penetrations too. This is the layer that stops an ice dam turning into a ceiling repair, and it is also the layer that gets quietly shortened on cheap quotes. We keep getting called out to roofs where somebody ran a single 36-inch course at the eave and called it done on a house with a two-foot overhang, which does not come close.

Synthetic underlayment over the field, not felt. New drip edge and gutter apron. Starter course. Then the shingles themselves, hip and ridge caps, and ventilation sized to the sheet we filed with your permit. Finally the cleanup, which means the Equipter catches the debris rather than your flowerbeds, and Pete runs a magnet over the yard and driveway twice.

The Two-Layer Rule Nobody Mentions Until It Is Too Late

Aurora's own permit handout answers this in its FAQ: can I add a third layer of shingles? No. If there are two or more existing roof layers, all of them must be removed before the new roofing goes on.

Why this matters to your wallet: a layover is cheaper than a tear-off, so a contractor pricing a layover on a house that legally needs a tear-off will look meaningfully cheaper than everyone else. Then either the permit gets refused, or the work happens without a permit and turns up in your closing paperwork years later. If one quote is dramatically under the others, this is the first thing to check.

The tell that you are on two layers already: unusually thick edges at the rake, and shingles that sit noticeably proud where they meet a wall. We will confirm it in the attic in about ninety seconds.

What Makes One Quote Cheaper Than Another

Six things, and only two of them are the shingle.

Whether it is a tear-off or a layover. How far the ice and water shield actually runs. Whether synthetic underlayment or felt. Whether the decking allowance is on the estimate or is going to be a conversation on the day. Whether ventilation work is included or the ridge vent is just going back on over the same blocked soffit. And whether the permit is priced in or you are expected to pull it yourself, which some outfits do and do not mention.

Put two quotes side by side on those six lines and the mystery usually evaporates.
