A roof certification in Arizona is a licensed roofer's written statement that a roof is watertight today and should stay that way for a stated term, usually 2 to 5 years, issued after an inspection and any repairs the roofer requires. It is not a warranty and it is not insurance. Buyers, lenders and insurance carriers ask for one because it puts a licensed contractor's name behind the most expensive single component of the house.
Most of the certification calls we take at Hardacker come out of a home sale somewhere in the Valley, and the questions are always the same: who pays, what does it cover, and what do we do about the line on page 14 of the home inspection that says "recommend evaluation by a licensed roofing contractor." This is the kitchen-table version.
What a roof certification actually is
Think of it as two steps bolted together. First, a roofer walks the roof and documents what is there: material, age, flashings, penetrations, drainage, and anything that is failing. Second, if the roof passes, or once the required repairs are done, the roofer signs a letter that says the roof should perform for a set term.
An Arizona roof certification is usually one or two pages on the roofing company's letterhead with the ROC license number on it. It names the property, the roof type, the inspection date, the repairs completed, the certification term, and the exclusions. The exclusions are the part almost nobody reads. We cover them below.
Who can issue one: a roofing contractor licensed by the Arizona Registrar of Contractors. Verify the license at roc.az.gov before you accept the paper. A certification from an unlicensed handyman is worth nothing to a lender, and it will not help you if the roof leaks in August.
Roof inspection vs roof certification
People use the two words interchangeably. They are different products, and the difference matters when you are deciding what to ask for during a sale.
What you get — Roof inspection: A written report with photos, a list of defects, and repair pricing. A snapshot of the roof on that day. · Roof certification: The inspection, plus any required repairs, plus a signed letter stating the roof should perform for a set term.
Who asks for it — Roof inspection: Buyers during the inspection period, sellers before listing, owners after a storm. · Roof certification: Lenders (FHA/VA especially), insurance carriers on older roofs, buyers on the BINSR.
Typical cost — Roof inspection: quoted when you book, often credited toward repairs. · Roof certification: inspection fee quoted when you book, repairs quoted separately.
Validity — Roof inspection: None. It describes the roof today with no commitment. · Roof certification: 2–5 years, set by the roofer based on condition. Transferable at closing if the letter says so.
A plain inspection tells you what you are buying. A certification adds the roofer's commitment to stand behind the roof for the term, which is why it costs more and why the roofer will insist on fixing anything marginal first. If you only need information, an inspection is enough. If a lender or insurer wants paper, you need the certification.
Who asks for a roof certification in Arizona
Buyers, during the inspection period, when the general home inspector flags the roof or the roof is older than about 15 years.
Lenders. FHA and VA appraisers look for a roof with at least two years of remaining life. If the appraisal notes roof condition, the underwriter will usually ask for a roofer's letter before closing. Conventional lenders ask less often, but they will when the appraisal flags something.
Insurance carriers. Many Arizona carriers now want a roof inspection or certification before binding a policy on a roof over 15 to 20 years old, and some will only write depreciated (actual cash value) roof coverage on older roofs without one. The Arizona Department of Insurance explains how roof age affects coverage at difi.az.gov.
Sellers, voluntarily, to take the roof off the table before the buyer's inspector gets up there.
What we look at during a certification inspection
We walk the roof. We do not look at it from the driveway. On a typical Phoenix house that means:
The field of the roof: cracked, slipped or missing tile; curled, bald or cracked shingles; blisters, cracks and ponding on foam and flat roofs.
Flashings: pipe jacks, roof-to-wall, chimney, skylights, and the valley metal. This is where most Valley roofs actually leak.
Penetrations: HVAC curbs, satellite mounts, solar standoffs, and the abandoned mounts somebody caulked over ten years ago.
Drainage: gutters, scuppers, drains and parapet caps on flat roofs, including the dust left by the last haboob, because that is what blocks scuppers.
Underlayment, where we can see it: at the eaves, at the ridge, and under the handful of tiles we lift. We cannot see all of it. That limitation drives the biggest exclusion in the certificate.
From inside: attic staining, daylight at penetrations, wet insulation, and ceiling stains that line up with a roof detail above.
You get a written report with photos, a repair list with pricing, and a plain statement of whether the roof qualifies as-is, qualifies after repairs, or does not qualify. "Does not qualify" usually means the roof is at the end of its life and the honest answer is replacement. Our post on repair versus replacement walks through that call.
The buyer vs seller playbook during the 10-day inspection period
The standard Arizona purchase contract gives the buyer an inspection period, 10 days by default, to inspect the house and then deliver a Buyer's Inspection Notice and Seller's Response, the BINSR. The seller gets a short window to respond, and the buyer gets a final window to accept the response or cancel with earnest money returned. The timelines are negotiable and your agent runs the calendar, but the roof has to fit inside it.
If you are the buyer
Order the general home inspection on day one or two. Do not wait.
If the inspector flags the roof, or the house is a tile roof built 1995 to 2008, or a shingle roof over 15 years old, book a roofer's inspection the same day. A Valley roofer can usually get on a roof in 2 to 4 business days. You need the written report in hand before the BINSR is due.
Decide what to ask for. On the BINSR you can request specific repairs, a seller-paid certification, a credit at closing, or a price reduction. Attach the roofer's priced repair list so the seller cannot argue about scope.
If the roof needs an underlayment replacement, which runs $10,500 to $16,000 on a typical tile house in 2026, ask for a credit rather than letting the seller hire the lowest bidder to do it in five days. You want to pick the contractor and the underlayment product.
Insist that any seller-completed repairs come with a receipt from a licensed roofer and a certification letter that transfers to you at closing.
If you are the seller
Get the roof inspected before you list. Paying for an inspection to learn what the buyer's roofer is going to find is the best money you will spend on the sale.
Fix what is found and get the certification in hand. Attach it to the Seller's Property Disclosure Statement. A 2- or 5-year cert on the listing takes the roof out of the negotiation and cuts the buyer's leverage on the BINSR to nearly nothing.
If the roof is at end of life, disclose it and price it in. Hiding worn-out underlayment is how sellers end up with a cancelled contract on day nine and a disclosure problem later.
When a BINSR arrives with a roof item, respond with your roofer's report, not an argument. Two licensed roofers rarely disagree about whether a pipe jack is cracked.
What a roof certification does NOT cover
Here is the fine print, and it is where buyers get burned. No roof certification in Arizona covers all of the roof, all of the time.
Underlayment life on tile roofs. This is the big one. The tile on a Phoenix roof lasts 40 to 50 years. The felt underneath it is the actual waterproofing and lasts 15 to 25 years. A certification is based on what the roofer can see, and we cannot certify 2,500 square feet of underlayment we did not look at. Most certificates say so in a sentence like "underlayment condition not warranted." Read our post on why tile roofs leak even when the tile looks fine before you buy a 2003 tile house on the strength of a cert alone.
Weather events. Wind, hail, lightning and falling debris are excluded. That is what your homeowners policy is for.
Damage by other trades. HVAC technicians, solar installers, satellite crews, pest control and painters walk on roofs and break things. A leak traced to foot traffic or a new penetration is excluded.
Drainage you did not maintain. On a flat or foam roof, scuppers clogged with monsoon debris are on the owner.
Anything inside the house. A cert covers the roof system. It does not pay for drywall, flooring or furniture if a leak happens.
Repairs by someone else. Most certs are void if another contractor touches the roof during the term. If you have a leak, call the roofer who issued the cert first.
How to read one: look for the term in years, any dollar cap, the transferability clause, the "visible and accessible" language, and the list of exclusions. If the letter is a single paragraph with no exclusions, it was written by someone who has never had to honor one.
When the home inspector flags the roof
General home inspectors are generalists. Most will not walk a tile roof because they are not insured for it and they would break tiles anyway. So the roof section of the report is often shot from the ground or a drone, and the recommendation is a liability line: "Recommend further evaluation by a licensed roofing contractor." That sentence is not a verdict. It is a handoff.
What to do with it:
Pull the roof photos from the inspection report and send them to the roofer when you book. We can often tell from the pictures whether this is a simple pipe-jack problem or an underlayment problem.
Get the roofer on the roof before the BINSR deadline. Ask for a written report that answers three questions: what is failing, what it costs to fix, and how many years of life are left.
Turn the findings into a BINSR ask. Cracked tile and a couple of pipe jacks: ask for repairs plus a cert. Worn underlayment or shingles at the end of their life: ask for a credit sized to the replacement quote and plan to do the work yourself after closing.
Do not let a seller's "it has never leaked" settle the question. Phoenix roofs do not leak in a dry year, then they leak the first week of monsoon. The underlayment under a 20-year-old tile roof is tired whether or not it has rained on it.
Our roof repair crews do a lot of pre-closing work on exactly this kind of list, and it moves fast once the scope is written down.
What it costs and how long it lasts
The cost of an Arizona roof certification inspection depends on roof size, pitch and material, and whether it involves a two-story walk or lifting tile; we quote it when you book. Repairs are extra and quoted separately. Some roofers credit the inspection fee toward repairs; ask before you book.
Validity is usually 2 years on older roofs and up to 5 years on roofs in good condition with a long runway left. The term is the roofer's call based on what was found. Nobody can honestly certify a 22-year-old felt underlayment for five years, and you should be suspicious of anyone who offers to. Lenders generally want at least 2 years. Certifications are written to the current owner and transfer to the buyer at closing only if the letter says so, so ask for that language up front.
Every certification we issue runs through the same inspection-to-report-to-repair process we use on any residential roofing job, and the repairs carry our workmanship warranty on top of the certification term.
