For a typical single-family home with architectural asphalt shingles, most projects land in the five figures, with size (measured in squares of 100 sq ft), pitch, stories, tear-off layers, decking condition and region moving the number substantially. Metal roughly doubles shingle money; tile and slate climb from there. Run your numbers in our calculators and see the full cost guide.

You are buying a system, not shingles: tear-off and disposal, decking repairs, underlayment, flashing, ventilation, labor that is skilled, insured and working at height, plus the overhead of a legitimate company (licensing, insurance, warranty reserves). The materials are usually only a third of the bill, which is why suspiciously cheap bids are cutting one of the other two-thirds.

Consistently, in three currencies: resale (roofs are top-of-list in inspections and appraisals, and roof age can decide insurability), transaction speed (an old roof stalls sales and invites renegotiation), and insurance premiums, which often drop on a new roof. Cost-vs-value studies routinely place roofing among the better-recovering exterior projects.

Repair wins while the field is sound and the problems are local, flashing, a leak line, storm-torn shingles. Replacement wins when repairs recur, the field is at end of life, or repair money would only buy a year or two. The honest crossover math is the whole subject of our repair-vs-replace guide.

Commonly: contractor financing programs, home equity products, and insurance proceeds for covered damage are the usual three, and reputable companies walk the options without pressure. What to avoid is financing that only exists to inflate the contract, one of the flags in our hiring guide.

By material: 3-tab asphalt 15-20 years, architectural asphalt 20-30, metal 40-70, wood 20-40 with upkeep, tile and slate 50 to a century-plus, with climate, ventilation and installation quality bending every range. The full table and the factors live in the lifespan guide.

The convergence test: age at or past the material range, widespread granule loss and bald spots, curling or cracked shingles across the field (not one slope), repeated leaks in different places, and daylight or moisture in the attic. Any one alone can be repairable; several together mean the field is done. Our warning-signs guide runs the checklist.

Codes commonly allow a second layer, and it saves tear-off cost, but it hides the decking (the thing most worth inspecting), adds weight, shortens the new roof, and complicates every future repair. Most quality-first roofers, us included, argue for tear-off in almost all cases.

Late spring through fall is prime (dry, warm enough for shingle sealant to bond), fall being the classic rush. Winter roofing is done successfully with cold-weather practices, and off-season scheduling can price better. Urgency beats season: an actively failing roof should not wait for June.

Most single-family asphalt replacements run one to three days: day one tear-off and dry-in, day two shingles and details. Size, pitch, weather, decking surprises and material (tile, slate and standing seam run longer) stretch the calendar. The process, start to final walkthrough, is mapped in the replacement guide.

Statistically, flashing: the metal at chimneys, walls, valleys and penetrations fails long before shingle fields do, with pipe-boot cracks, nail pops and ice dams close behind. The stain rarely sits under the entry point, water travels rafters before dripping. The leak guide runs the hunt properly.

Contain (bucket, move belongings, poke a small drain hole in a bulging ceiling to prevent collapse), document with photos for any claim, then call for a proper diagnosis. Skip the DIY tar smear, it hides the evidence and rarely holds. Emergency tarping exists for the storm-torn cases, per the emergency guide.

Small, defined repairs (a pipe boot, a short flashing run, a handful of shingles) sit in the low hundreds; complexity, steepness, and chasing water damage push toward four figures; and past a threshold the repair-vs-replace math takes over. Legitimate roofers quote after diagnosis, not from the driveway.

No, only paused. Interior patches and pans manage symptoms; the water is still entering the assembly and rotting what it touches. Every real fix happens at the weather surface, which is why attic-side foam and tar jobs are on our list of expensive false economies.

Because the source is conditional: an ice dam that only backs up in freeze-thaw, a flashing gap that only takes wind-driven rain from one direction, or attic condensation in cold snaps, the impostor that mimics leaks per the ventilation guide. Intermittent stains deserve diagnosis precisely because they vanish.

For most homes and budgets: architectural asphalt shingles, the value standard. For longevity per dollar: standing-seam metal. For a century roof with the structure to carry it: tile or slate. For flat planes: single-ply membranes. The honest comparison across all of them is the materials guide.

Over one ownership horizon, often: 40-70-year service, wind and fire resilience, energy reflectivity and low upkeep against roughly double shingle money upfront. Over a short horizon, less so, the payback is in the decades. The full ledger is in the metal guide.

Match the architecture first (the color guide maps styles to palettes), then climate: lighter reflects heat in cooling country, darker suits heating country and hides winter staining. Resale favors the calm middle, weathered wood, driftwood, slate gray, over statements.

Where aesthetics or HOA rules block racked panels and the roof needs replacing anyway, sometimes; otherwise conventional panels on a good roof deliver more watts per dollar. The full accounting, Tesla and its rivals included, is in the solar shingle guide.

They are not extras; they are the system: underlayment is the backup weather plane, ice-and-water membrane the cold-climate eave insurance, drip edge the code-required edge protection, and ventilation the thing keeping the attic from cooking the shingles. Bids that omit them are cheaper the way a car without brakes is cheaper.

For sudden, storm-caused damage, generally yes, minus deductible, and paid at replacement or depreciated value depending on your policy form. For wear, age and neglect, no. The claim mechanics, documentation to depreciation recovery, are walked through in the insurance guide.

Date-stamped photos from ground and (safely) ladder level, wide shots and closeups, interior stains included; keep damaged material samples; get a roofer inspection report fast; and report promptly, claims sour with delay. Never sign an assignment of benefits on the door-knock, per the storm guide.

Around 1 inch (quarter size) for asphalt shingle bruising, smaller with old brittle shingles or soft-metal accessories (vents and flashings dent first and prove the storm). The bruise-vs-blister call and the claim path are in the hail guide.

Weather claims are treated more kindly than liability claims, but claim frequency matters, and in hail states the calculus shifts again. The honest rule: claim real, substantial damage; absorb cosmetic nicks below or near your deductible; and decide with documentation either way.

Safety first (downed lines, sagging ceilings), then document everything before touching anything, then emergency tarping by a professional if water is entering, then the insurance call, and only then contractor conversations, in that order, with signatures last. The sequence is the storm guide chapter one.

Verify license and both insurances (liability and workers comp) directly, demand local references and addresses you can drive past, insist on a written scope naming materials by product, and treat pressure tactics, storm-chaser door knocks and huge deposits as exits. The full vetting protocol is the contractor guide.

Three is the classic, from genuinely local companies quoting the same written scope so the numbers compare. Discard the outlier low bid rather than celebrating it, in roofing the cheap bid is usually the expensive one, per the companies guide.

Usually yes for full replacement, often not for minor repairs, always locally variable. Legitimate contractors pull their own permits as routine; a roofer asking you to pull it (or skip it) is waving a flag. Details in the permit guide.

The revealing five: Who exactly is on my roof (employees or subs, and who supervises)? What does your workmanship warranty cover, in writing, for how long? How do you protect landscaping and find every nail? What happens if you find bad decking? And what manufacturer certifications back your material warranty? Confident companies enjoy these questions.

For the start (walkthrough, surprises like decking calls) and the end (final inspection, magnet sweep, warranty paperwork), ideally yes; the noisy middle needs no audience, though pets and home-office workers may want to relocate for a day. A good crew runs the day the same either way.
