calculators.
Roofing, shingle and fence calculators for preliminary exterior material planning.
Plan the quantity before the purchase.
Exterior projects combine geometry with exposure, pitch, layout and local installation requirements. These tools estimate roof area, squares, bundles or fence materials while keeping waste and spacing assumptions editable. Safe measurement and product-specific instructions remain essential before purchase or installation.

Roofing Calculator
Estimate sloped roof area, roofing squares and bundles for a simple gable roof.
Roof area & squaresShingle Calculator
Estimate roofing squares and shingle bundles for a simple pitched roof.
Squares & bundlesFence Calculator
Estimate fence panels, posts, sections and material cost from total run length.
Panels, posts & costA practical estimating sequence
- Use plans or safe ground-based measurements whenever possible.
- Record roof pitch, fence run length and opening locations accurately.
- Adjust waste for valleys, hips, corners, gates and layout complexity.
- Confirm product exposure, bundle coverage and local code requirements.
Common mistakes to avoid
- Using building footprint as sloped roof area without a pitch factor.
- Ignoring starter, ridge, flashing, underlayment or ventilation materials.
- Counting gate openings as ordinary fence panels.
- Measuring a roof in unsafe conditions.
Roof & exterior FAQ
What is a roofing square?
One roofing square represents 100 square feet of roof surface. The number of bundles per square depends on the specific shingle product.
Does the roofing calculator include pitch?
Yes. It applies a pitch multiplier to a simple rectangular building footprint. Complex roofs should be divided into sections or measured from plans.
Are posts and gates included in a fence estimate?
The fence calculator estimates posts, sections and cost from editable spacing assumptions. Gate hardware, bracing and site-specific terminal posts should be verified separately.
