Roofing contractors are tradespeople who handle the full lifecycle of your roof-from inspections and leak repairs to full tear-offs and replacements. They work with all major roof types (asphalt shingles, metal, tile, slate, flat membranes), coordinate permits, and follow building codes and manufacturer specifications.
Typical responsibilities include:
- Assessing roof condition, measuring your roof, and recommending repair or replacement
- Removing old roofing, disposing of debris, and protecting landscaping
- Repairing or replacing damaged decking (the wood sheathing under the roof)
- Installing underlayment, ice and water shield, flashing, ventilation, and new roofing
- Sealing penetrations around chimneys, skylights, and vents
- Cleaning up, scheduling inspections, and registering warranties
On Roof Lists you can find roofing companies near you that offer these services. The directory does not pre-vet providers or perform any roofing work, so always verify a contractor's license, insurance, and references yourself before hiring.
Why a quality roof matters
Your roof is a weather shield, a structural component, and a big chunk of curb appeal. A well-installed roof:
- Stops leaks that can lead to mold and costly interior damage
- Helps keep heating and cooling bills in check with proper ventilation and reflective options
- Boosts resale value and can improve insurance insurability
- Reduces noise, resists wind uplift, and protects against ice dams when detailed correctly
Cut corners on materials or workmanship and you may face premature failure, voided warranties, and repeated repairs. Choosing the right pro-and the right system-pays off for decades.
Roof repair vs. replacement: how to decide
Not every problem requires a new roof. Consider these guidelines:
-
Repair may be enough when:
- Damage is localized (a few missing shingles, one small leak)
- The roof is relatively young with plenty of life left
- Flashing around a chimney or vent has failed but shingles are otherwise sound
-
Replacement is often the better choice when:
- The roof is near or beyond its expected lifespan
- There are widespread cracks, curling, granule loss, or sagging
- Multiple leaks appear in different areas or there's storm damage across large sections
- You already have multiple layers of roofing-many codes limit overlays
A trusted local contractor can inspect the deck, underlayment, and ventilation to recommend the most cost-effective path.

How to use Roof Lists
Roof Lists is a service directory that helps you:
- Search roofing contractors by city or ZIP code
- Scan business profiles for services, materials, photos, and customer feedback
- Request quotes from multiple companies to compare options
Important: Roof Lists does not pre-screen or endorse individual businesses. Before you sign anything, confirm state licensing where required, ask for proof of general liability and workers' compensation insurance, and check references from recent, nearby projects.
How to choose a roofing contractor
A great contractor brings skill, organization, and communication. Look for:
- Local presence and experience: A physical address, years in business, and recent jobs nearby
- Proper credentials: Licensing where required, insurance, and any manufacturer certifications (for example, shingle maker "preferred" or "master" status)
- Detailed written estimates: Clear line items for tear-off, materials, flashing, ventilation, disposal, and contingencies for deck repairs
- Solid warranties: Separate labor (workmanship) and manufacturer (materials) warranties, with terms in writing
- Professional process: Permits handled, daily cleanup plan, on-site supervision, weather contingency plans, and final inspection
- Good communication: Straight answers about products, schedule, crew composition (in-house vs. subcontractors), and change-order procedures
Red flags:
- Only verbal quotes or pressure to sign today
- Unusually low bids without detail
- No proof of insurance
- Storm-chaser tactics after severe weather, asking to handle your entire insurance claim without transparency
Typical roof replacement costs (and what affects them)
Every roof is unique, but these ballpark figures can help you plan. Total cost depends on roof size and complexity, local labor rates, material choice, tear-off needs, and code requirements in your area.
- Asphalt shingles (architectural): commonly the most affordable; many homes fall roughly in the mid-to-high four figures to low five figures for a full replacement, depending on size and complexity
- Metal roofing (standing seam or metal shingles): typically higher upfront than asphalt; strong wind and longevity performance
- Tile (concrete or clay) and slate: premium options with long lifespans; higher material and structural requirements
- Flat roofs (TPO, EPDM, PVC): pricing varies by membrane type, insulation, and edge details
Cost drivers you'll see itemized on quotes:
- Tear-off and disposal of existing layers
- Deck repairs or replacement per sheet (often priced as a contingency)
- Underlayment type and ice/water shield coverage
- Flashing and ventilation upgrades
- Roof pitch, story height, and complexity (valleys, dormers, chimneys, skylights)
- Regional labor and permit fees
- Warranty level and manufacturer/system certification requirements
Tip: Ask each contractor to price the same scope and materials so you can compare apples to apples. If one bid is far lower, request clarification-something may be missing.
Key components of a roof system
A quality roof is more than shingles. Make sure your quotes address the whole system:
- Decking: Plywood or OSB sheathing; damaged areas should be replaced
- Underlayment: Synthetic felt or hybrid; provides secondary water protection
- Ice and water shield: Self-adhered membrane in valleys, eaves, and critical transitions
- Drip edge and gutter apron: Metal edging that directs water away from the fascia
- Starter strip: Ensures proper seal and wind resistance at eaves and rakes
- Field shingles or panels: The visible roofing-shingle, metal, tile, slate, or membrane
- Flashing: Metal details around chimneys, skylights, sidewalls, and penetrations
- Ventilation: Intake (soffit) and exhaust (ridge or roof vents) to move attic air and prevent heat/moisture buildup
- Ridge cap and hip caps: Finishing pieces that seal and ventilate ridge and hips
- Fasteners and sealants: Nails or screws specified by the manufacturer for wind and corrosion resistance
- Gutters and downspouts: Not always part of roof contracts, but critical for drainage
Request product brands and model lines in writing, not just generic descriptions.
Roofing materials at a glance
- Asphalt shingles
- Pros: Budget-friendly, widely available, many styles and colors
- Considerations: Lifespan varies by grade and climate; proper ventilation matters
- Metal roofing (steel, aluminum, copper)
- Pros: Excellent wind/hail resistance, long life, recyclable, reflective options
- Considerations: Higher upfront cost; requires skilled installation and precise flashing
- Tile (concrete/clay)
- Pros: Distinctive look, durability, fire resistance
- Considerations: Heavy-may need structural checks; breakage risk during service
- Slate
- Pros: Premium appearance and longevity
- Considerations: High cost and weight; requires expert installers
- Wood shakes/shingles
- Pros: Natural aesthetic
- Considerations: Fire rating and local code restrictions; more maintenance
- Flat roof membranes (TPO, EPDM, PVC)
- Pros: Common for low-slope sections; energy-efficient white options
- Considerations: Seaming method and edge details are critical to performance
- Composite/synthetic
- Pros: Mimic slate or shake with lighter weight and lower maintenance
- Considerations: Verify warranty, hail rating, and UV performance
What to expect: installation timeline
Timelines vary by season and crew size, but a typical replacement flows like this:
- Site visit and estimate: 1-3 days to receive a written proposal after inspection
- Contract and scheduling: Materials ordered; permits applied for as needed
- Tear-off and dry-in: 1 day for many single-family roofs; larger or complex roofs may take longer
- Deck repairs: Same day as tear-off if minor; extensive work can add time
- Underlayment, flashing, and roofing installation: 1-3+ days depending on roof size and material
- Cleanup, punch list, and final inspection: Same or next day
- Warranty documents: Ask for copies and registration details before final payment
Weather can extend timelines. A good contractor will communicate delays and keep your roof "dried-in" between phases.
Prep checklist for homeowners
A little prep makes installation smoother:
- Move vehicles from the driveway; crews need space for dumpsters and deliveries
- Protect attic items from dust; remove fragile décor from walls and shelves
- Cover landscaping or outdoor furniture; ask the crew how they protect your property
- Keep kids and pets indoors during tear-off
- Confirm where power is available and which outlets the crew may use
- Discuss satellite dishes, solar equipment, or holiday lights ahead of time
- Notify neighbors about potential noise for 1-3 days
How to compare roofing quotes the smart way
Make sure each bid answers the same questions:
- Exact products: brand, line, color, and thickness/gauge where relevant
- Underlayment and ice/water shield coverage
- Flashing plan: step flashing, chimney counter-flashing, skylight kits, valley metal
- Ventilation strategy: intake/exhaust balance and ridge vent details
- Edge metals: drip edge and gutter apron included?
- Accessories: pipe boots, attic fans, starter strips, ridge caps
- Tear-off layers and disposal fees
- Decking repair allowance (per sheet price and trigger)
- Permits and inspections included
- Workmanship and material warranty terms, transferability, and exclusions
- Schedule, daily start/stop times, cleanup, and magnet sweep for nails
- Payment milestones and change-order process
- Who performs the work: in-house crew or subcontractors; on-site supervisor name
If a bid seems vague, ask for a revised, itemized proposal. Clear scopes reduce surprises.
Smart questions to ask a roofing contractor
- Are you licensed (if required in my state) and fully insured with workers' comp and general liability?
- How many installations like mine have you completed in the last 12 months?
- Which manufacturer certifications do you hold for the products you're proposing?
- Can you provide recent, local references and photos?
- Who will be on-site supervising, and how many crew members should I expect?
- What's your plan for protecting my landscaping and siding?
- How will you handle bad weather mid-project?
- How do you ensure proper attic ventilation and calculate the needed net free area?
- Will you replace all flashing or only reuse some? How will you flash my chimney/skylights?
- What is included for deck repairs, and how are unforeseen costs handled?
- What are the workmanship and manufacturer warranty terms? How do I register them?
- What inspections and permits are required, and who schedules them?
- Will you provide lien waivers from suppliers/subcontractors upon final payment?
Signs you might need roofing service
Call a pro if you notice:
- Leaks or water stains on ceilings or in the attic
- Missing, cracked, curling, or blistering shingles
- Excessive granules in gutters or at downspout exits
- Rusted, loose, or missing flashing; deteriorated rubber pipe boots
- Sagging roof planes or soft spots on decking
- Light shining through the attic or mold growth on rafters
- Persistent ice dams, high energy bills, or poor attic ventilation
- Storm damage from hail, wind, or fallen limbs
- A roof that's reached or exceeded its typical lifespan for the material
Insurance, permits, and warranties
- Insurance claims: If storms caused damage, document everything with photos, prevent further water entry, and contact your insurer. It's wise to get at least two detailed contractor estimates for comparison. Understand your deductible and whether your policy pays actual cash value (ACV) or replacement cost value (RCV).
- Permits and codes: Many localities require roofing permits and inspections. A reputable contractor will follow local codes covering ventilation, ice barriers, and overlay limits.
- Warranties: You'll typically receive two protections-manufacturer (defects in materials) and workmanship (installation quality). Ask about term length, what voids coverage, and whether the warranty is transferable.
Energy, sustainability, and add-ons
- Ventilation and insulation: Balanced attic ventilation and adequate insulation can improve comfort and extend roof life.
- Cool roofs and colors: Reflective shingles or light-colored metal can reduce heat gain in sunny climates.
- Recycling and disposal: Ask whether the contractor recycles asphalt shingles where facilities exist.
- Gutters and guards: Consider new gutters or leaf protection while scaffolding is already in place.
- Skylights and sun tunnels: Replacing aging skylights during a roof project can prevent future leaks.
