Roofing calculators

Fall clearance calculatorFind the clearance a personal fall arrest system needs below the anchor: free fall + deceleration + worker height + a safety margin.R-value thickness calculatorFind the insulation thickness for a target R-value: thickness = target R divided by the material's R per inch.Ladder setback calculatorSet a ladder safely with the 4 to 1 rule: base setback = height to contact divided by four.Coating coverage calculatorFind the paint or coating needed: gallons = area x coats / the coverage rate, plus waste.Roof squares calculatorEstimate roofing squares from the building footprint and the pitch: roof area = footprint x the pitch multiplier, and one square is 100 square feet.

Roofing readiness checks

Envelope readinessA 2 minute check on whether the air barrier, insulation, and moisture control are working together, before high bills, condensation, or rot prove they are not.Roof maintenance readinessA 2 minute check on whether your low-slope roof is on a real maintenance program, before a clogged drain or a skipped inspection turns into an interior leak and a voided warranty.Drone inspection readinessA 2 minute check on whether your drone inspections are flown legally, capture the thermal data that matters, and feed a report the crew can act on.Facade access readinessA 2 minute check on whether your swing stage, mast climber, or scaffold is rigged, tied, loaded, and tied off so a failure does not drop someone off the building.Fall-protection complianceA 2 minute check on the program OSHA actually looks for, before a fall or an inspection finds the gap for you.Jobsite safety readinessA 2 minute check on whether your crews are actually protected from the hazards that kill in the trades, before an injury or an OSHA inspection finds the gap for you.Siding install readinessA 2 minute check on whether your siding job has the water barrier, flashing, and install details that actually keep the wall dry.Single-ply seam and attachment QA readinessA 2-minute check that catches the missing trial weld, the unprobed seam, and the untested deck before they cost you the warranty.Storm claim documentation readinessA quick check of whether your crew has the verification, test squares, photos, and legal guardrails a storm claim needs before tear-off.
