What matters for project planning
The severe-weather exposure is the fact that matters here. Central Indiana has documented severe-weather activity, and roofing is the assembly that takes it first — which makes wind rating, fastening and the condition of the deck beneath the covering the consequential decisions rather than shingle brand. Roof replacement is reviewed by the Building Safety Office. The soil and growth facts have little bearing above ground, though the housing-era point still holds: what is under a 1980s roof differs from a 2015 one.

Check the parcel, not just the city
General city data doesn't tell you a specific parcel's flood zone, historic status, permit needs, soil conditions, or what's actually behind the walls. Confirm those details with the city and your chosen provider before work starts.
