"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"

"Like that they could find the problem with my roof leak that three others did not. while fixing the leak, they corrected other problems as well for siding and vents. They were like others who have worked on my siding, left behind a handful of nails and cigarette butts on my lawn to be throw away. I will use Griffitts in the future, since they know how to do things correctly!"

Roofing FAQs, answered by experts

The terms “roof shingles” and “roof tiles” are sometimes used interchangeably, but the term “shingles” most often refers to asphalt, rubber, metal, or slate shingles, and the term “tiles” normally means they’re made from clay or concrete. In all cases, shingles are small, rectangular components that a roofer layers in an overlapping pattern to protect the structure underneath from the elements.

There are several pros and cons of flat roofs. One disadvantage of flat roofs is that you lose potential attic space because it's flat. Flat roofs tend to pool water and because they lack an angle, any leak in the roof—usually due to a bad seal—has the potential to let in a lot of water. They don’t work well in climates with snow. Flat roofs are also structurally weaker than sloped roofs.

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.

Some people prefer to use connectors consisting of galvanized metal to replace the birdsmouth cuts on the rafter board. Common names for these metal pieces include hurricane ties and variable-pitch connectors. Making birdsmouth cuts is more cost-effective than purchasing these connectors for each rafter. However, because making large birdsmouth cuts to accommodate extra-wide exterior walls can weaken the rafter, a connector may be the better option in some cases.

Roofers can install roof vents. Updating, upgrading, or simply replacing your roof's existing vents is common when installing a new roof. If you're looking to upgrade your ventilation system with a powered version, a local HVAC professional can also help with the task. If adding roof vents to your home is necessary while installing an addition or during other renovation work, your contractor will handle or hire out the venting work.
