"Central Illinois Roofing and Renovation got the job done in two days removing our old roof and replacing it with a new medal roof. They were so professional in the business part and even more professional in their work and politeness. My Wife and I are very happy with them and our new roof. They also did a very good job cleaning up all leftover debris. We're looking forward to calling them again on other needed projects in the future. Thank you for have them on your list. P. Young"

Roofing FAQs, answered by experts

Roof vents are an essential part of a roof, as they promote energy efficiency by keeping warm, humid air at bay. The roofing material, especially asphalt shingles, will not last as long as it should (about half of its manufacture life) if the attic is not ventilated. Also, going without ventilation means having a warm attic that demands more from your air conditioning system (and your wallet, once the bills come). Ridge vents and roof vents also prevent a host of other icky moisture-related problems like rot, mold, and mildew.

There are several signs that indicate you’ll need new underlayment. Clear signs include missing or damaged roofing and exposing the underlayment to the elements. Additionally, if you notice water damage in your home by the roof after a storm, it could indicate that your underlayment may need to be replaced. If your gutters aren’t draining properly, it could also lead to rotting or water damage to the underlayment.

Technically, a flat roof can be raised, but it’s extremely expensive, and there would not be much of a point. Most homeowners raise the roof in their homes to access the space between their existing ceiling and the roof, but flat roofs don’t have this space. Therefore, you can raise a flat roof, but it involves heavy structural modification.

If you’re choosing between a roof overlay and a tear-off, opt for a tear-off and full roof replacement instead of a roof overlay if possible. The cost savings from an overlay can easily be eclipsed by repair costs, the effects of structural damage from the additional weight, and needing to replace your roof sooner than expected. A full replacement will last longer and is less likely to need damage repaired over time.

Costs depend on material, labor, and additional features like underlayment or insulation.
