With more than 50 years of industry experience, we offer professional knowledge and expertise that homeowners depend on. That's why we are one of the most referred roofing contractors serving Hammond and surrounding areas in Northwest Indiana and Chicagoland. Our long track record of successful projects, from roof replacement to siding installation, and more, inspire total confidence, and customers know they can trust us to provide reliable products and consistently meticulous workmanship.

"I regret hiring this company. The sales rep was pushy and misleading about what was included ? I believed gutters, soffit, and fascia were part of the job, but later was told it was just a cleaning (which never happened). The crew left open holes in my roof on day one, and the ?one-day job? dragged into four days of loud, late work with sloppy cleanup and debris left behind. When they said the job was done, I found exposed nail heads, poor trim work, and granule loss on my brand-new roof. They had to send crews back multiple times, and I still had to hire two independent inspectors at my own expense. I was also charged over $1,000 extra for wood and for trim I didn?t want ? now I?ll have to pay to remove and replace it. Despite repeated promises from management that they would ?take care of me,? my calls, emails, texts, and photos went ignored after one brief call from the GM. Poor workmanship, poor communication, and no accountability. I would not recommend this company."

Roofing questions, answered by experts

Some hail storms can cause serious damage to your roof and shingles, but unless your roof is aging or already in poor condition, it’s unlikely to necessitate a full roof replacement. It is rare for an insurance company to approve a roof replacement after a hailstorm.

Underlayment exists under your tile roof. It helps protect your home by acting as a secondary water barrier. Often, when roof tiles fall off, underlayment that's in good condition can temporarily keep water from getting into the home. However, immediate replacement of missing tiles is crucial to avoid additional roof damage. 

Whether flashing goes over or under shingles depends on the type of flashing. For example, with step flashing, the shingles go on top, but they overlap one another. So technically, flashing goes both over and under shingles. But generally speaking, flashing goes under shingles and beneath the house siding. And in most cases, you can't see the flashing from the ground.

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

Walking on any roofing material is dangerous, so you should avoid it if you can, but if the need arises, you should know that you can walk on a concrete tile roof without damaging it. Try to step on the bottom portions of the tile that are supported by the lower layer, and distribute your weight evenly across both feet and hands, if possible.
