ARYLIC ROOFING: PREPARING A METAL ROOF

The following procedures apply to all metal roofs, including flat-seam, standing seam, and metal-shingle roofs. We do not recommend using rust consolidators: always remove rust, replace missing metal, and fill as needed with patching compounds. Small areas that have been cleaned and patched can be primed with any good rust-inhibiting primer, but use Conservation Technology Metal Primer for large areas. Call for advice about coating metal roofs in good condition where reinforcing fabric may not be required.

scrub with detergent

STEP 1: Scrub the roof with detergent solution.

pressure wash

STEP 2: Pressure-wash with a generous amount
of water to remove all traces of the detergent.

scrape

STEP 3: Scrape any residue, such as thick
accumulations of asphalt patching compounds.

wire brush

STEP 4: Wire brush any rusted areas,
preferably with a cup wheel in a grinder.

patch

STEP 5: Patch deteriorated metal or low areas where
water might collect using a metal repair compound

prime spot

STEP 6: Prime bare metal and patched
areas with Conservation Technology Metal Primer.
