Question

Should I replace or paint my steel roofing?

Asked by Noel F Davis
North Creek, NY

The current roof is old steel. The interior insulation under the steel is new spray foam. Snow build-up has been a problem; I expect that ice-dams will be less of a problem with the new insulation. Question: should I paint or replace the steel roofing? Cost is an important factor.

I would suggest you explore getting your old roof coated with a cool roof (high SRI or solar reflectance index) coating.

  • Most good roofers these days are familiar with this, but you may have to call on someone from a nearby city.
  • However, if your roof is in good enough shape to be coated, it's a very affordable solution.

Look up elastomeric (you should look up several companies' websites). For Kynar, try this link: http://www.arkema-inc.com/index.cfm?pag=1291
