How To Use The Calculator

To estimate the total cost for your new siding, enter your ground measurements, number of levels, home type, number of doors & windows, old siding removal, house insulation type, and new siding material.

This tool aggregates and analyzes pricing from contractors if different regions of the US. This means that when you select your location, you will get an accurate price quote for that particular region. Alternatively, if you want to get just a general sense of siding installation costs, you can select the National Average setting.

For accurate results, take your time to measure the house properly. Go from corner to corner with a tape measure, and get the Length and Width of your house. If you get sizes like 26' 7", it is best to round it up to 27', otherwise the quote will be less than what contractor will give you.

Measuring-Roof-SlopeRoof Slope: When measuring / estimating roof slope, you can either use your judgement or use a 2' level + tape measure to get accurate reading. Go into your attic, position the level horizontally, one end against the rafter. Then measure the distance from the opposite end of the level, up to the rafter. Divide this distance by 2. This will be your slope.

Example: If your distance is 14", the slope is 7 over 12 or just 7. Follow the provided diagram.

Roof Types: If you have a FLAT or HIP roof, select "FLAT" option for Roof Slope. In either case, your house does not have gables, so now siding will be installed above roof base.

Gable Side (roof width): Make sure when entering house dimensions that the Gable Side is entered into appropriate field. Your gables will be calculated base on this dimension and roof slope. If you enter wrong measurement into this field, the calculation will be off.

Other options: Select number of floors in your home, job complexity (use your judgement, but if you have multiple bump-outs / built in bays, etc, of if your house is Victorian style with all kinds of decorative pieces, use medium or difficult option). Select new insulation type, and number of windows / doors to be wrapped with flat stock aluminum.

Removal of old materials: Note that old plastic / vinyl / aluminum siding must always be removed, before new VINYL siding is installed. Vinyl CAN be installed over wood siding. For other materials, you must always remove old siding down to wall flat boards.

Asbestos siding: If you have old asbestos shingles on your walls it is best to install new (vinyl) siding on top, without removing asbestos. Otherwise your cost of siding a house will be 3 times more that is estimated by our calculator. Removing asbestos is VERY expensive and can only be done by certified contractors. The whole area should be then concealed to minimize / eliminate asbestos dust. Never let a regular siding contractor remove asbestos shingles.

Siding Installation Cost vs Return On Investment

Exterior siding prices Replacing old siding can be a very expensive project, especially if you want to install higher end, materials such as James Hardie, or natural wood. Many homeowners wonder if installing quality siding is a smart investment that can boost house value.

The answer is - Yes!!! According to the National Association Of Realtors, exterior projects, such as installing new siding bring some of the best returns on investment, compared to other remodels. According to research, you can recoup about 80-83% of vinyl siding cost, at resale.

For premium fiber cement products, such as Hardie Plank, the returns are 80-85% In general, prospective buyers perceive Hardie siding to be more upscale and durable than vinyl, and are willing to pay more for it.

Wood siding offers an overall lower ROI, of about 70-75% Keep in mind that its also more expensive compared to other types of siding. This means that if you are considering siding replacement as a way to boost your home's curb appeal, it may not be worth it to invest in natural wood materials.

To give you more specific data, if your new siding costs $12,000, it will add around $9,600-9,800 to the resale value of your house.

Depending on your location, some siding materials may be perceived as more desirable and valuable than others. Its best to consult with your realtor to determine which product will deliver the best return on investment at resale.

    Hello, how can I tell which states are in which region? It may seem intuitive, however I’ve been reading Energy Star maps till I’m blue in the face and the South-Central area includes the Carolinas; where do they fall on this site as far as region goes?
