Frequently Asked Questions About Roof Installation and Replacement

From our convenient location in New Baden, Ill., Crown is able to handle roofing jobs across the St. Louis Metro East, including cities in Clinton, Madison, Marion, Monroe, Randolph, St. Clair, and Washington Counties. All of our manufacturer-trained, highly-experienced installers live and work in the communities they serve.

Installing a new roof on top of an old one is not recommended. Sure, you may save money in the short run without the need for a roof tear off, but it’ll cost more in the long run because the life expectancy of your new roof will be reduced by half, and in most cases, void your warranties.


If a contractor installs a second roof layer, the air flow becomes constricted, causing the shingles underneath to smother and overheat. As a result, the old shingles dry out and curl up, damaging the new shingles sitting on top of them. Plus, double layers cause your home to retain a greater amount of heat, forcing your air conditioning system to work harder and driving up your energy bill.

There are a number of indicators that suggest it’s time for a roof placement, including a persistent leak, unexplained mold inside your home, torn, cracked or curling shingles, a loss of granules, missing shingles or a visible underlayment, and flashing pulling away from the structure.

Asphalt shingles are covered with ceramic granules that reflect water and light to protect the underlying material, and ultimately your roof. As UV light and heat dry out your shingles, water wears away at any loose granules. The more granules lost, the faster your roof will deteriorate.

Curling is an indication that the oils are starting to evaporate, and the shingle is shrinking, exposing the plywood underneath. Water can then deteriorate the wood decking, which allows water to enter your home.

At Crown, we do not recommend tar as the only seal on your chimney. The recommended method of flashing a chimney is to use a quality ice and water underlayment, aluminum step flashing, and depending on what your chimney is made of, a surface or inset counter flashing.

No, you don’t have to be home for our inspection, but we would like you to be present when we explain our estimate so we can answer any questions you may have.

Unlike many roofing estimates which are performed by a temporary sales team, all Crown quotes are handled by co-owner Bernie Thebeau who has years of experience in the field. There is no charge for new roof estimates – however, there may be a charge for repair and inspection estimates.

Because every roof is different in terms of area, pitch, story level, and installation difficulty, a precise estimate requires an in-person inspection. In addition, the style of roofing shingles can also impact the final roof replacement cost. By understanding your goals, needs and budget, Crown co-owner Bernie Thebeau can help determine the best roofing option for you.
