Roofing square at gastos
Libreng kalkulator ng gastos sa bubong
Ilagay ang measured roof area, waste allowance, at material at labor rates per roofing square para tantiyahin ang job quantity at cost.
Libre, walang sign-up, at nananatili sa browser ang mga inilagay na halaga.
Paano gamitin ang roofing cost calculator
Ilagay ang sukat ng bubong o kuwentahin mula sa building dimensions at pitch. Itakda ang waste, materyales at labor. Working cost estimate ito, hindi site inspection o binding replacement quote.
Ilagay ang area o building dimensions
Gamitin ang tunay na roof surface, o length/width sa dimensions method na gumagamit ng napiling pitch. Huwag gamitin ang pinagsamang floor area ng maraming palapag bilang footprint.
Itakda ang pitch at allowance
Sa dimensions method, piliin ang rise bawat 12 unit na run. Ihiwalay ang waste allowance para sa order; hindi pareho ang measured area at purchase quantity.
Ilagay ang materials at labor
Per roofing square ang rate, katumbas ng 100 ft², o gumamit ng labor-hours at hourly cost. Sundin ang displayed units sa metric. Huwag idagdag ang buong labor kung kasama na ang installation sa material rate.
Repasuhin ang buong proyekto
Suriin ang adjusted area, squares, materyales at labor. Hiwalay na presyo ang tear-off, disposal, deck repairs, flashing, access, permits, overhead at tubo kung wala pa sa input.
Magkano ang pagpapalit ng bubong?
Magsimula sa measured surface at nakasulat na scope. Ang 1,700 ft² bubong ay hindi laging katumbas ng 1,700 ft² bahay: slope, overhangs, garahe at palapag ay nakakaapekto. Material grade, removal, access at lokal na labor ang humuhubog sa quote.
Bilang dated US context, binabanggit ng GAF ang 2025 U.S. Roof Report: average replacement cost $17,631. Halo-halong proyekto iyon, hindi presyo ng partikular na 1,700 ft² bahay. Kumuha ng kasalukuyang lokal na quotes bago bumili.
Ang mga talahanayan ay tahasang budget scenarios, hindi kasalukuyang market survey. Palitan ang bawat sample rate ng supplier/contractor figures para sa property mo.
Roofing squares = measured area ÷ 100
Installed base budget = roof area × installed unit price
Installed base budget = roof area × installed unit price
Sa palagay na $6–$9/ft² installed, 1,700 ft² ay $10,200–$15,300 base. Linawin kung kasama ang removal, trim, repairs at permits bago tawaging kumpletong estimate.
Paghahambing ng roofing materials
Magkakaiba ang hitsura, bigat, installation at maintenance. Ihambing ang buong roof system, hindi bundles o panels lamang. Hindi kasama sa covering-only price ang underlayment, fasteners, edge details at labor.
| Covering | Sample installed / ft² | Kuwenta sa 1,700 ft² |
|---|---|---|
| Asphalt shingles | $6–$9 | $10,200–$15,300 |
| Metal roofing | $9–$20 | $15,300–$34,000 |
| Concrete/clay tile | $11–$22 | $18,700–$37,400 |
| Wood shakes/shingles | $10–$16 | $17,000–$27,200 |
| Natural slate | $22–$36 | $37,400–$61,200 |
Illustrative inputs lamang, hindi supplier offer, national average o garantiya ng contractor price. Hindi ipinapalagay na kasama ang structure, tear-off at unusual access.
Asphalt: basic, architectural at premium
Karaniwang may ilang grade kaya magandang batayan sa bids. Hingin ang eksaktong produkto, kulay, wind requirements, accessories at warranty.
- Three-tab: medyo patag at paulit-ulit na profile. Suriin ang availability at angkop na local wind requirements.
- Architectural: laminated layers para sa makapal at dimensional na hitsura. Depende pa rin sa system ang details/warranty.
- Premium laminates: mas masalimuot na hugis/finish ay dagdag material at handling. Hindi guaranteed service life ang mahabang warranty label.
- Recycled content: humingi ng dokumentasyon at kumpirmahin ang local rebate eligibility; huwag ipagpalagay ang claim o rebate.
Metal: panels, shingles at standing seam
Maaaring tumagal kung angkop at maayos ang assembly. Gauge, coating, uri ng metal, fastening, trim at fabrication ay nakakaapekto sa presyo.
- Corrugated/exposed fastener: ihambing ang panel kasama ang fasteners, sealants at patuloy na inspection.
- Metal shingles: individual pieces na may sariling detailing at labor.
- Standing seam: raised seams at concealed attachments; ipresyo ang transitions, penetrations at custom fabrication.
Tanungin kung may old-covering removal, disposal at deck prep. Hindi direktang kapantay ng all-in asphalt quote ang metal materials lamang.
Concrete at clay tiles
Kailangan ng tamang support at attachment. Alternatibo sa clay ang concrete, ngunit hindi awtomatikong magaan. Ipasuri ang structural load ng tunay na produkto.
- Concrete: specification, finish, battens at installation method.
- Clay: hugis, firing, finish at matching accessories. Ingatan ang marupok o lumang piraso.
Hindi maintenance-free ang assembly dahil matibay ang tile. Underlayment, flashings at sirang units ay maaaring maunang mangailangan ng trabaho.
Wood shakes at shingles
Maaaring cedar o angkop na species. Mas textured ang split shakes, mas pantay ang sawn shingles. Grade, treatment, exposure at installation ay kasinghalaga ng hitsura.
Pag-usapan ang fire requirements, ventilation, moisture at product-specific maintenance. Alisin ang debris at tingnan ang decay. Gumamit lang ng treatment/cleaner na inirerekomenda; hindi para sa lahat ang annual sealant.
Natural slate
May natatanging finish at posibilidad ng mahabang buhay. Bigat, breakage allowance at specialist labor ay maaaring mahal. Kumpirmahin ang structural capacity bago umorder at ihiwalay ang strengthening.
Kailangan pa ring alagaan ang flashing, fasteners at transitions. Gumamit ng experienced roofer at magtago ng compatible spare pieces.
Roofing labor: removal, installation at access
Ihiwalay ang pagtanggal ng luma sa pagkabit ng bago. Kasama sa crew time ang setup, protection, loading, carrying, cleanup at inspections. Kulang ang tantiyang shingle attachment time lang.
| Labor item | Sample / ft² | 1,700 ft² halimbawa |
|---|---|---|
| Simple lightweight removal | $1.50–$3.00 | $2,550–$5,100 |
| Heavy/difficult tile o slate removal | $3.00–$5.00 | $5,100–$8,500 |
| Simple new covering installation | $3.00–$4.00 | $5,100–$6,800 |
| Complex/steep installation | $4.50–$7.00 | $7,650–$11,900 |
$1.50 removal + $3 installation sa 1,700 ft² ay $7,650 labor. Heavy removal $5 + complex install $7 ay $20,400. Magkahiwalay na halimbawa, hindi low/high limits ng lahat ng trabaho. Dagdag ang materyales/disposal maliban kung kasama.
Bakit magkaiba ang quote ng crews?
- Lokasyon: sahod, insurance, transport at skilled-worker availability.
- Access/safety: hoists, scaffolding, protected paths, fall protection at limitadong staging.
- Geometry: valleys, hips, dormers, skylights, chimney at intersecting slopes ay dagdag cuts/details.
- Kondisyon: maraming old layers, rotten deck o concealed damage na lumalabas matapos buksan.
Hingin ang kasamang bilang ng layers at agreed unit price para sa extra. Hindi all-inclusive promise ang mababang base labor.
Roof size, pitch at taas ng gusali
Roof footprint ang gamitin, hindi kabuuan ng lahat ng floors. Sa constant slope, factor = √(1 + (rise ÷ run)²); i-multiply sa horizontal area. Sukatin kada plane ang complex roof at isama ang overhangs.
Sloping area = horizontal area × √(1 + (pitch rise ÷ 12)²)
One-story sa 5:12 pitch
Eksaktong factor 13/12, humigit-kumulang 1.0833. Simple footprint, walang dagdag overhang o waste, at illustrative installed rate $6–$9/ft².
| Horizontal footprint | Sloping area | Sample base budget |
|---|---|---|
| 1,000 ft² | 1,083.3 ft² | $6,500–$9,750 |
| 1,500 ft² | 1,625 ft² | $9,750–$14,625 |
| 2,000 ft² | 2,166.7 ft² | $13,000–$19,500 |
| 2,500 ft² | 2,708.3 ft² | $16,250–$24,375 |
| 3,000 ft² | 3,250 ft² | $19,500–$29,250 |
Two-story na magkapantay ang floors
Hatiin sa dalawa ang total interior floor area para sa approximate footprint, saka 5:12 factor. Hiwalay sukat ang garahe, porch, unequal floors at overhangs. Maaaring dagdag access cost ang taas kahit maliit ang roof.
| Total interior floor area | Approximate roof area | Sample base budget |
|---|---|---|
| 1,500 ft² | 812.5 ft² | $4,875–$7,312.50 |
| 2,000 ft² | 1,083.3 ft² | $6,500–$9,750 |
| 2,500 ft² | 1,354.2 ft² | $8,125–$12,187.50 |
| 3,000 ft² | 1,625 ft² | $9,750–$14,625 |
| 3,500 ft² | 1,895.8 ft² | $11,375–$17,062.50 |
Parehong footprint, tatlong slopes
Sa horizontal 1,700 ft², nagbabago ang surface bago pa idagdag ang steep-slope labor. Unrounded areas ang gamit sa budget na $6–$9/ft².
| Slope | Factor | Sloping area | Base budget |
|---|---|---|---|
| 3:12 | 1.0308 | 1,752.3 ft² | $10,514–$15,771 |
| 5:12 | 1.0833 | 1,841.7 ft² | $11,050–$16,575 |
| 9:12 | 1.2500 | 2,125 ft² | $12,750–$19,125 |
Hiwalay na adjustment ang taas/access
Maaaring kailangan ang material lift, dagdag fall protection at mas mahabang handling sa second story. Maaaring hindi kasya ang normal equipment sa steep/narrow access. Hingin ang itemized hoisting, scaffolding at special-access cost, hindi unexplained percentage sa lahat.
Hypothetical 10% access allowance sa $12,000 ay $1,200. Palagay, hindi standard surcharge; huwag ulitin kung kasama na sa labor ang kondisyon.
Paano binabago ng lokasyon ang estimate?
Hindi nasasakop ng national number ang bawat kalye/property. Supplier distance, wages, demand, permits, weather at building requirements ay mahalaga. Ihambing ang eksaktong scope/material specification.
Parehong 1,700 ft² ang worksheet upang rate lang ang magbago. Illustrative ang mga presyo, hindi measured city averages o published indices.
| Market scenario | Sample local / ft² | 1,700 ft² budget |
|---|---|---|
| National | $8 | $13,600 |
| New York City | $12 | $20,400 |
| Los Angeles | $10 | $17,000 |
| Chicago | $9 | $15,300 |
| Seattle | $9.50 | $16,150 |
| Denver | $8.50 | $14,450 |
| Miami | $9 | $15,300 |
| Houston | $7.50 | $12,750 |
Palitan ng written local quotes. Maaaring mahal ang difficult roof sa low-cost region at mura ang simple project sa high-cost city. Suriin ang wind, snow, moisture at permit sa tunay na address.
Local comparison factor = local quoted unit price ÷ comparison unit price
$10 local ÷ $8 comparison = 1.25. Dalawang quote lang ang inilalarawan, hindi pangkalahatang multiplier ng lungsod o materyales.
Roof removal at pagtatapon ng debris
Higit sa pagtanggal ng covering ang removal. Kumpirmahin ang layers, protection ng exposed deck kapag nagbago ang panahon, pagdadala sa container at disposal payer. Iba ang handling ng mabigat na tile/slate sa asphalt.
Ihiwalay ang labor at waste handling
- Removal labor: per square/ft² na may layers at material.
- Hauling/disposal: container fee, weight allowance, tipping fee o area rate.
- Site protection: halaman, driveway at magnetic cleanup kung angkop.
- Extra waste: presyo ng additional layers, deck damage at overweight loads.
| Scenario | Labor + disposal assumptions | Combined rate | 1,700 ft² total |
|---|---|---|---|
| Isang lightweight covering | $1.75 + $0.50/ft² | $2.25/ft² | $3,825 |
| Heavy/complex covering | $3.50 + $0.90/ft² | $4.40/ft² | $7,480 |
Aritmetika lamang, hindi price list. Hindi awtomatikong katumbas ng per-area fee ang container allowance. Kung labor at disposal na ang removal rate, huwag magdagdag ng buong debris charge muli.
Karagdagang materyales at roof details
Assembly ang bubong. Maaaring manatili ang lumang problema kung tatakpan ang sira o gagamitin ang failed details. Hingin ang quantity, unit, product at labor bawat component. Quote organization ang mga halimbawa, hindi market averages.
Decking/sheathing
Plywood/OSB ang pinakakabitan ng roof system. Maaaring hindi humawak ang fasteners sa malambot, delaminated o sirang panel. Suriin ang exposed deck at pagkasunduan ang dokumentasyon/approval ng concealed damage.
Ihiwalay ang sheet price at install. Walong 4 × 8 ft sheets sa $38 = $304 materyales. Ang 256 ft² replacement sa dagdag $2/ft² labor = $512; total $816. Hiwalay ang framing work.
Underlayment
Felt/synthetic sa pagitan ng covering at deck bilang bahagi ng water-shedding system. Ihambing compatibility, installation, exposure limit at warranty, hindi roll price lang.
- Felt: 1,700 ft² × assumed installed $0.20 = $340.
- Synthetic: 1,700 ft² × assumed installed $0.35 = $595.
Dagdag purchase quantity ang overlaps. Hindi ibig sabihin nito na weatherproof nang walang hanggan o ligtas lakaran ang unfinished roof.
Ice-and-water membrane
Maaaring kailangan sa vulnerable eaves, valleys at transitions. Depende ang lawak sa local code, klima, assembly at manufacturer, hindi elevation lang.
Sukatin ang treated zone maliban kung full coverage. 300 ft² sa hypothetical installed $1.20 = $360. Kung linear feet, itanong ang kasamang lapad.
Fascia at soffits
Tinatapos ng fascia ang edge at madalas suporta ng gutter. Isinasara ng soffit ang ilalim ng eaves at maaaring may ventilation. Isama ang sirang trim, baradong vents at mahinang transitions.
Halimbawa: fascia 120 linear ft × $10 = $1,200; soffit 120 × $7 = $840. Kumpirmahin ang sukat, finish, vent area, access at gutter removal/reinstall. Magkaiba ang detailing/maintenance ng PVC, wood, aluminum at vinyl.
Flashing at pipe boots
Kailangan ng maayos na integration sa roof-wall junction at penetrations. Hindi sapat na repair ng underlying system ang visible sealant lang.
| Detail | Quote unit | Sample line |
|---|---|---|
| Step flashing sa wall | Linear foot | 40 ft × $8 = $320 |
| Chimney counterflashing | Linear foot o buong assembly | 20 ft × $14 = $280 |
| Vent pipe boots | Bawat isa ayon sa size/spec | 3 × $35 = $105 |
| Valley flashing | Linear foot | 30 ft × $9 = $270 |
Linawin alin ang bago, reusable matapos inspection at paano konektado sa wall/underlayment. Idagdag lamang ang wala sa base para hindi doble ang materyales.
Mga palatandaang kailangan ng professional assessment
1. Edad at maintenance history
Hanapin ang installation date, produkto, repairs at warranty. Karaniwang ilang dekada ang usapan sa asphalt, mas maraming dekada sa metal at maaaring mas matagal sa tile/slate. Depende sa produkto, install, klima at alaga ang buhay. Hindi replacement schedule ang warranty.
| Roof family | Published planning reference | Suriin |
|---|---|---|
| Three-tab asphalt | Mga 20 taon sa InterNACHI chart | Brittleness, nawawalang units, granule loss at flashing |
| Architectural asphalt | Mga 30 taon sa parehong chart | Lamination, exposure at installation |
| Metal | 40–70+ taon sa Interlock guidance | Fasteners, coatings, seams at corrosion |
| Concrete/clay tile | 50–100+ taon sa industry-association guidance | Broken pieces, support, underlayment at flashing |
| Natural slate | 60–125+ taon sa National Park Service guidance | Slate quality, configuration, lokasyon at support details |
Magkakaibang materials/kondisyon, hindi uniform schedule. Sources: InterNACHI · Interlock · Tile Roofing Industry Alliance · National Park Service.
Broad references, hindi garantiya. Ipasuri ang kondisyon, hindi palitan ang maayos na bubong dahil lang umabot sa isang numero.
2. Sirang/nawawalang covering
Tingnan ang malawak na curling, cracking, missing shingles at exposed areas dahil sa granule loss. Maaaring repairable ang lokal na sira; recurring failures sa maraming planes ay dahilan para sa replacement assessment.
3. Tubig sa loob
Ceiling stains, attic drips, damp insulation at persistent mold ay kailangang imbestigahan. Maaaring malayo ang entry point. Puwede ring plumbing, condensation o wall details; hindi lahat ng stain ay buong roof failure.
4. Hindi maipaliwanag na heating/cooling changes
Maaaring kailangan ang insulation, ventilation at air-leak assessment. Hindi garantiya ng energy savings ang roof replacement; alamin muna ang dahilan.
5. Moss, algae at debris
Makapal na moss/debris ay nakakaipon ng moisture at nakakasagabal sa drainage. Dark algae stain lang ay hindi structural failure. Product-appropriate cleaning ang kailangan; maaaring makasira ang agresibong paraan.
Suriin mula sa ligtas na lugar. Ipaubaya ang steep access, invasive assessment at repairs sa equipped professionals.
Buong halimbawa ng roofing estimate
Mga halimbawang numero lamang, hindi presyo sa merkado. Gamitin ang tunay na gastos at sukat.
Measured asphalt replacement
40 × 40 ft horizontal area sa 5:12 pitch: 1,600 ft² o 16 ground squares.
- Sloping area = 1,600 × 13 ÷ 12 = 1,733.33 ft².
- Material-only assumption = 1,733.33 × $3 = $5,200.
- Labor = 100 worker-hours × $45 = $4,500.
- Base = $5,200 + $4,500 = $9,700.
- Dagdag $2,500 removal/disposal at $300 permits = $12,500 bago ibang excluded scope.
Isama ang waste, deck repairs, overhead, tubo at tax kung naaangkop. Apat na tao × 25 oras ay 100 worker-hours, hindi 25 labor-hours.
Installed laban sa material-only quote
Sa 1,700 ft², Quote A $8/ft² kasama materyales/install. Quote B $4/ft² materyales at $6,800 labor.
- A: 1,700 × $8 = $13,600.
- B: (1,700 × $4) + $6,800 = $13,600.
Pareho ang base, hindi pa ang value. Ihambing ang removal, underlayment, flashing, ventilation, warranty at disposal. Ang dagdag $6,800 labor sa A ay double counting.
Deck damage na nakita matapos buksan
Base quote $14,000. Inaprubahan ng owner ang anim na damaged sheets sa installed $115 bawat isa.
Approved extra = 6 × $115 = $690
Revised price = $14,000 + $690 = $14,690
Revised price = $14,000 + $690 = $14,690
Ilakip ang larawan, dami at written approval. Mas malinaw ang documented unit-rate change kaysa unexplained contingency. Tiyaking may tax/disposal ba ang $115.
Mga tanong tungkol sa roofing cost
Magkano ang bubong ng 2,000 ft² bahay?
Tukuyin muna kung interior, footprint o measured roof surface ang 2,000 ft². Huli lang ang direktang imumultiply sa installed roof rate. Sa tunay na 2,000 ft² roof, sample $6–$9 ay $12,000–$18,000 bago exclusions.
- Material grade at system accessories.
- Slopes, dormers at transitions.
- Old-layer removal, disposal, decking at permits.
Maaaring mas maliit ang footprint ng two-story kaysa one-story na pareho ang interior area. Sukatin muna.
Paano buuin ang replacement budget?
- Sukatin horizontal area kasama overhangs/extensions.
- Gamitin ang slope factor o sukatin bawat plane.
- Pumili ng complete spec at material-only/installed rate.
- Isama removal, disposal at known deck repairs.
- Ilista underlayment, membrane, flashing, trim, permits at inspections na wala pa.
- Kumpirmahin height, access at local requirements.
- Repasuhin written total, assumptions at unit prices sa concealed damage.
Material-only ang gamitin kung hiwalay ang labor. I-round ang orders ayon sa packaging matapos sukatin ang area.
Ano ang average cost sa North Carolina?
Hindi sapat ang statewide average para sa partikular na bubong. Coastal exposure, labor, delivery, permits, area at covering ay magkakaiba. Hindi kami naglalahad ng hindi verified na average bilang current price.
Measured 2,000 ft² sa illustrative $7 installed ay $14,000; sa $11 ay $22,000. Kumuha ng equivalent local bids at suriin exclusions. Hindi North Carolina market measurements ang sample rates.
Magkano ang pagpapalit ng 1,000 ft²?
Sa assumed installed $6–$9/ft², base $6,000–$9,000. Idagdag lang excluded work. Maaaring may minimum crew, transport/equipment charges sa maliit na project, kaya hindi palaging kalahati ang presyo kapag kalahati ang area.
Complex penetrations, premium material, difficult access at concealed damage ay maaaring magtaas nang malaki. Hingin ang measured scope.
May contractor financing ba?
May nag-aayos sa pamamagitan ng lenders. Depende ang availability, term, deposit at approval sa offer/applicant. Ihambing cash price, financed amount, APR, fees, schedule at total repayment, hindi monthly lang.
Ihiwalay ang tunay na 0% introductory APR sa deferred interest at basahin ang matapos promo. Huwag ipagpalagay ang approval. Ang loan calculator ay model; lender disclosure ang masusunod sa kontrata.
Sasagutin ba ng homeowners insurance?
Depende sa policy, sanhi, exclusions, deductible at settlement. Covered sudden event ay iba sa age, wear o neglected maintenance. Replacement cost at actual cash value ay magkaiba ang out-of-pocket.
Dokumentuhin nang ligtas at kontakin insurer bago umasa sa reimbursement. Hindi coverage decision ang contractor estimate. Itanong ang roof age, depreciation, matching at recoverable depreciation sa claim.
Tataas ba ang resale value dahil sa bagong bubong?
Maayos at magandang roof ay nakakadagdag buyer confidence at nakababawas repair concerns. Recovery sa sale ay depende sa market, lumang kondisyon, material at ibang bahagi ng bahay. Hindi guaranteed kapantay ng gastos.
Halimbawa $18,000 spent at $12,000 added sale value ay 66.7% recovery; $6,000 hindi nabawi. Illustration, hindi promised return o appraisal. Tingnan local evidence at gamitin ang ROI calculator sa sariling assumptions.
Bakit mahal ang bagong bubong?
- Materials: covering, underlayment, membranes, fasteners at details.
- Skilled labor: removal, preparation at install.
- Waste: hauling, containers at disposal.
- Permits: administration at required inspections.
- Access: height, slopes, staging at safety equipment.
- Business costs: insurance, licensing, supervision, overhead at warranty.
Dapat malinaw ang inclusions. Maaaring wala sa cheapest total ang items na kasama sa iba; scope muna bago price comparison.
