Recoat or replace? Score your flat roof in 60 seconds.

An elastomeric recoat runs $1.50–$2.50/sqft. A full tear-off replacement is $7–$11/sqft. Recoating the wrong roof means you'll do the tear-off in 3 years anyway — plus the coating. Answer 8 questions and we'll tell you which is honest for yours.

What we see

The three flat roofs that get recoated when they shouldn't.

The saturated foam roof

SPF that's been coated 3 times and the top 1" is soft when you walk it. Recoating adds weight to a roof that's already failing under the water it holds.

The 25-year mod-bit

Granules are 90% gone, seams have 'alligator' cracking. Coating will bridge the surface for 12–18 months then delaminate in sheets.

The ponded TPO

1/2" of standing water 3 days after rain. No coating warranty covers ponding — spending $6k to void every warranty makes no sense.
