Should I replace or paint my steel roofing?
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.
