How Old Is the Roof? What It Means When You Buy or Sell on the Northside

Of all the things that come up between contract and closing, the roof causes more renegotiation than almost anything else in the house. It's expensive, it's hard to see from the sidewalk, and both the lender and the insurance company care about it. Whether you're buying or selling, here's how the roof actually gets handled, and where I've seen deals hit a pothole.

Our roofs are not all alike

On the Northside, "the roof" can mean very different things. Many of our two-flats, greystones and courtyard buildings have flat roofs behind a parapet wall. You can't see them from the street at all, and their weak spots are drainage, seams, flashing and the coping along the top of the parapet. Our bungalows and frame houses usually have pitched shingle roofs, where the questions are age, layers and ventilation. And if you're buying a condo, the roof is usually not yours alone, which changes the conversation entirely (more on that below).

Chicago winters are hard on all of them. Freeze and thaw, snow that sits for weeks, and ice that builds up at the edges find every weak seam. So a roof's age is only part of the story. How it has been maintained matters just as much.

A home inspection is not a roof inspection

This is the most common misunderstanding. A general home inspector looks at the whole house in a few hours and reports on the roof as one item among dozens. Depending on the pitch, the height, the weather and their own policy, they may walk the roof, look from a ladder at the edge, or inspect from the ground. All of that is fine for a general inspection, but it isn't what a roofer gives you.

A roofing contractor gives you an estimate of the roof's remaining life, the number of layers, the condition of the flashing and drains, and a written price for whatever needs doing. When your inspection report says something like "roof nearing end of life, recommend evaluation by a licensed roofing contractor," take that line seriously. That referral is the real decision point, not a formality.

What Illinois sellers have to disclose

Illinois sellers of most homes, including condos and buildings of up to four units, complete the Residential Real Property Disclosure Report. One of its questions asks directly whether the seller is aware of leaks or material defects in the roof, ceilings or chimney.

Two things to understand about that form. First, it covers what the seller actually knows. A seller who genuinely doesn't know the roof is near the end of its life hasn't done anything wrong by checking "no." Second, it doesn't ask the roof's age. So for a buyer, a clean disclosure isn't a guarantee. If the roof matters to you, and it should, ask about its age and history in writing and get the answers in writing.

For a seller, my advice is simple: do the right thing. A known leak that gets quietly painted over is the kind of thing that can follow you after closing, and it turns a repair conversation into a "what else are they hiding" conversation. (This is general information, not legal advice. Your real estate attorney can speak to your situation.)

The insurer and the lender have opinions too

Even when buyer and seller are both comfortable, two other parties can force the issue.

• The insurance company. Homeowners insurers look closely at roof age and condition. A buyer can be surprised late in the process by a much higher quote, a carrier that won't write the policy, or coverage that pays less for an older roof. Your lender requires insurance in place at closing, so get a quote with the roof's age in hand during the inspection period, not the week before closing.
• The appraiser. On FHA and VA loans, the appraiser looks at the roof's remaining life, not its age. FHA's standard is a roof with at least about two years of life left. If it falls short, a repair or replacement can become a condition of the loan. Conventional lenders can also call for repairs when the appraiser notes a problem.

Buying a condo? The roof belongs to the association

In most condominium buildings, the roof is a common element. The association maintains and replaces it, and every owner pays for it, either through reserves or through a special assessment. So for a condo buyer, the real question isn't "how old is the roof?" but "is the building ready to pay for it?"

When a condo is resold in Illinois, the seller has to obtain the association's resale disclosures and make them available to the buyer. They include any capital expenditures the association expects in the current or next two fiscal years, and the status of the reserve fund. Read those, and read the board meeting minutes if you can get them. A roof replacement that's already being discussed is much better to learn about before you buy than after.

If you're buying

• Ask the roof's age early, before you're emotionally committed to the house.
• Get a roofer up there during your inspection period if the inspector flags anything or the roof is clearly older.
• Ask about layers. A second layer of shingles makes the eventual replacement a bigger job.
• Call your insurance agent with the roof's age before your inspection period ends.
• Ask whether any warranty transfers to you, and how. Transfer windows are often short.
• For a condo, read the association's disclosures for planned roof work and reserves.

If you're selling

• Know what you have before a buyer tells you. A roofer's look before you list means no surprises mid-contract, when you have the least room to maneuver.
• Gather the paperwork: the original invoice, what was installed, any warranty and its transfer terms, and records of repairs.
• Decide on purpose whether to replace or offer a credit. Replacing before listing removes an objection and gives buyers one less thing to worry about. A credit costs less up front but invites a negotiation. Neither is automatically right.
• Don't paint over a leak. A fresh patch of paint on one ceiling is one of the first things an inspector notices.

A documented roof is worth more in a negotiation than an undocumented roof of the same age. We cover the rest of the prep work in How to Prepare Your Northside Home to Sell.

How roofs actually get negotiated

When an inspection turns up a roof problem, the outcome is usually one of these, and they aren't equally good for both sides:

• The seller repairs or replaces it before closing. Buyers, lenders and insurers like this. The catch: the seller chooses the contractor, and the buyer inherits the workmanship.
• A price reduction. Sellers often prefer it. But it doesn't fix the roof, so it won't satisfy an appraiser who has made the repair a condition of the loan.
• A credit at closing. Often a fair middle ground. Lenders limit how much a seller can credit, though, so the credit may not cover the whole job.

Whichever side has a written, itemized estimate from a real roofer usually does better. Numbers argued from a line on an inspection report tend to be round, high and contested. Numbers from a contractor's estimate tend to stick.
