Why Merrillville Homeowners Choose Alamo
What Our Customers Say
Davis was very helpful and understanding of our problem with the roof. He also did a very good job explaining our options and new roofing systems. Alamo is a great company and they do great work. I would highly recommend!
We had a tree fall on our house and it damaged our roof and siding. We called the guy who put our roof on 5 years prior and he wouldn’t respond to us. We called Alamo and our worries were over! Alamo worked with our insurance company but went way beyond. Insurance only wanted to repair the damage even though it was 2/3 damaged. Our shingles would be mismatched but Alamo gave us a new roof and brand new siding! They even covered our deductible! They’re professional, do great work and we called them back the next year to roof and side our garage so everything matches! Don’t hesitate. Call Alamo!
Amazing service and work from Alamo! Davis was super professional in his quote and follow-thru. Thanks for a great job!
