Roof size calculator
Roofers price by the square (100 square feet of roof). This estimates your roof's area from the house's footprint and pitch.
An estimate for planning only. Hips, valleys, dormers and several roof levels change the real figure; a roofer measures before quoting.
Insurance claim windows
Homeowner policies set their own deadlines for reporting storm damage, usually counted from the date of the storm. If you think a hailstorm damaged your roof, find its date in the records above, then read the "duties after loss" section of your policy and ask your insurer or agent to confirm the deadline in writing.
Hail damage to shingles is often hard to see from the ground, and only an inspection on the roof can show whether a roof was damaged. The records here show where hail was reported, not which buildings it hit.
This is general information, not legal or insurance advice.
