Roofers are busiest from late spring to early fall, so booking in winter usually means shorter waits. Spring and early-summer hailstorms in Missouri bring waves of insurance repair work. After a big storm, get more than one quote and check the license or registration before signing.
We scored 632 O'Fallon roofers on ten factors, weighted as shown. A business is ranked when its trade is confirmed and it has 3 or more Google reviews or a claimed profile. A business with no Google reviews scores zero on rating, review volume and recency. Other unknown factors are left out, not counted as zero. Scores last refreshed October 22, 2026.
Paid placement never changes a rank or score. Featured businesses are paid, labelled, limited to 3 and shown above the ranking, outside it.
