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 684 Dellwood roofers on 8 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. Unknown factors are left out of the score, not counted as zero. Scores last refreshed October 22, 2026.
