Roofing & Exterior Calculators

How much to order
Materials and quantities from your measurements.
Gravel
Work out how many tons and cubic yards of gravel to order for a driveway, path or bed from its length, width and depth, with the packing allowance built in.
Retaining Wall Block
Count the blocks, caps, base gravel and drainage stone for a retaining wall, and check whether your block is made to stand as tall as you want.
Paver Patio Material
Calculate every material for a paver patio or walkway — how many pavers (with pattern waste) plus the gravel base and bedding sand in cubic yards and tons.
Deck Footings & Posts
Figure out how many footings and posts your deck needs and how big each footing must be — sized from the deck dimensions, post spacing, and your soil type using the IRC / DCA6 design load. Includes concrete to order.
Roof, siding, windows and doors
What the outside of the house costs to repair or replace.
Roof Repair Cost
Roof repairs cost $150–$1,000 for minor fixes, $1,000–$3,000 for a damaged section, and $3,000–$6,000+ for major work. Price your damage and material — and see when a repair bill means replace instead.
Roof Replacement Cost
Estimate what a roof replacement will cost. Compare asphalt shingle, metal, and tile by roof size, pitch, and tear-off, and see a realistic low-to-high installed price range.
Standing Seam Metal Roof Cost
Estimate the installed cost of a standing seam metal roof — by metal (steel, aluminum, zinc, or copper), seam type (snap-lock vs. mechanical-lock), roof size, and complexity. See why copper and zinc cost 2–3× steel.
Skylight Installation Cost
Installing a new skylight costs $1,500–$4,700 depending on type — and replacing an existing one runs just $800–$2,400. Compare fixed, ventilating, and $500–$1,000 tubular sun tunnels, priced per unit.
Gutter Cost Estimator
Estimate what new gutters will cost to install. Compare vinyl, aluminum, steel, and copper by linear footage, add downspouts and gutter guards, and see a realistic low-to-high installed price range.
Gutter Guard Cost
Estimate the cost to add gutter guards to your existing gutters — by guard type (screen, mesh, micro-mesh, reverse-curve), professionally installed vs. DIY, with the access premium for tall or steep roofs. See the range and what DIY saves.
Chimney Repair Cost
Chimney repair costs $200–$850 for common fixes like caps and crown patches — up to $15,000 for a full rebuild. Price your specific repair, from flashing leaks to liner replacement, with inspection and permit costs included.
Chimney Sweep & Inspection Cost
Estimate what a chimney sweep and inspection should cost — by service (cleaning, inspection, or both), what the chimney vents (gas, wood fireplace, or wood stove), inspection level (1 vs. 2), creosote buildup, and number of flues.
Vinyl Siding Cost Estimator
Estimate the cost to replace your home’s siding with vinyl. Enter your footprint and stories — no wall measuring — pick a grade and tear-off option to get wall area, siding squares, and an installed cost range.
Stucco Repair vs. Re-stucco
Compare patching stucco against a full re-stucco by damaged area, wall size, and system (traditional vs EIFS). Get a clear verdict — with the two rules that decide it: how much of the wall is damaged, and whether water has gotten behind it.
Brick Repointing Cost
Estimate brick repointing (tuckpointing) cost by area, joint condition, and access height — with the historic soft-brick lime-mortar premium built in. See what drives the per-square-foot price and why old brick needs lime, not Portland cement.
Window Replacement ROI
Estimate the cost of replacing your windows, how much you recoup at resale (cost vs. value), your net cost, and an honest look at the real — usually modest — energy savings.
Exterior Door Replacement Cost
Estimate the installed cost to replace an exterior door — entry, sliding or french patio, or storm. See the price range by material (steel, fiberglass, wood), configuration (sidelights, double), install depth, and add-ons like a storm door or smart lock.
Garage Door Repair vs. Replace
Should you repair or replace your garage door? Tell us what's broken and how old the door is and get a recommendation — plus repair and replacement costs side by side, using the contractor 50%-of-replacement rule.
Pressure Washing Cost
Estimate pressure washing cost by surface — driveway, patio, deck, house siding, or roof — and compare hiring a pro to renting a machine yourself. See where DIY actually saves and why roofs must be soft-washed, not blasted.
Driveway, yard, fence and drainage
Everything from the walls out to the property line.
Driveway Repair vs. Replace
Should you fill the cracks, resurface, or replace your driveway? Answer three questions about your asphalt or concrete drive and get a recommendation plus the cost of all three options side by side.
Gravel Driveway Maintenance Cost
Estimate the true yearly cost of maintaining a gravel driveway — regrading, gravel top-ups, dust control, and pothole repair — by size and whether you DIY or hire it out. A realistic upkeep budget, not a one-time number.
Concrete Removal Cost
Estimate the cost to demolish and haul away a concrete slab — patio, driveway, pool deck, walkway, or any flatwork. See the price range, per-square-foot cost, and debris weight, plus what drives the number (size, thickness, rebar, access, and disposal).
Fence Installation Cost
Estimate fence installation cost by length, material, and height — chain link, wood, vinyl, aluminum, or composite — with gates and old-fence removal included, plus every material priced side by side for your yard.
Fence Staining Cost
Estimate the cost to stain or seal a wood fence — DIY materials vs. hiring a pro — by fence length, height, sides, and finish (clear sealer, semi-transparent, or solid stain). See how many gallons you need and what a pro should charge.
Shared Fence Cost Split
Splitting a property-line fence with a neighbor? Estimate the fence cost by material and length, set your agreed split, and see exactly what you owe versus what your neighbor pays.
Deck Repair vs. Replace
Should you refinish, repair, or replace your deck? Answer two questions about its size and condition and get a recommendation — plus the cost of all three, with pressure-treated wood vs. composite for a rebuild.
French Drain Cost
A French drain costs $10–$30 per foot in the yard, $30–$90 for deep exterior perimeter runs, and $4,000–$17,000 for an interior basement system. Price your water problem by type and length.
Basement Waterproofing Cost
Estimate basement waterproofing costs by method — interior sealant, interior drainage with a sump pump, or exterior membrane — priced per linear foot of wall, with an honest guide to which fix matches your problem.
Basement Crack Repair Cost
Price a basement or foundation crack repair by what the crack actually looks like — $250–$800 per crack for injection, or thousands if it's horizontal. Includes which material works on your crack and when it's structural.
About Roofing & Exterior Calculators
Your roof and exterior are your home's first line of defense against the elements, and they're also among the most expensive systems you'll maintain. A single miscalculation—whether it's underestimating shingle quantity, misjudging gutter capacity, or misunderstanding replacement costs—can leave you either overspending or underprepared for weather damage. Our roofing and exterior calculators eliminate guesswork by converting your specific measurements into accurate material lists, cost projections, and maintenance timelines. You'll know exactly how many squares of shingles you need, whether your gutters can handle your home's rainfall, and what realistic budgets look like for your climate and roof type.
These calculations matter because roofing and exterior decisions happen under time pressure. A storm damage assessment demands quick answers. A contractor quote needs verification. A DIY project requires precision.
Our tools let you input your home's actual dimensions and get reliable numbers in minutes rather than days. You can compare material options side-by-side, understand the real cost difference between asphalt and metal roofing, and plan maintenance spending before problems develop. Whether you're evaluating a contractor's estimate, planning a replacement project, or simply checking what you should realistically budget next year, having accurate calculations puts you in control of decisions that protect both your investment and your family's safety.
