Should I replace or paint my steel roofing?
Average Rating: ( 0 votes)
Current roof is old steel. New spray foam is interior insulation under the steel. Snow build-up has been a problem; expect that ice-dams will be less of a problem w/ new insulation. Question: paint or replace 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.
