Residential and Commercial Roofing

Although invisible to most people, roofing products have evolved dramatically. Approximately 25 years ago, fiberglass became the shingle mat of choice. Shingle asphalt is modified to make the shingles more pliable and durable. Special granules are added to help protect roofs from the damage of UV light. Computer-aided color design increases the amount of selection and enhances the beauty of today's shingles.


Siding and Exteriors

Casey Exteriors uses only the only the best vinyl siding for your home: The Royal Dura Technology System. The key to the Dura Technology Process is a special ROYALSIDE Compound: a proven blend of the world's finest raw materials. This blend, together with our exclusive DURA impact modifiers and premium ingredients, forms the base for a tougher, longer lasting siding.



Homeowners, just like you, have always had many reasons and needs for choosing quality replacement windows for their homes. Anything from low maintenance, lighting, ventilation to even decorative flair. However, a window's function does not end there. Well-designed windows will provide warmth during winter's chilly day, keep your home cool during summer's intense heat.

What is Important to me?

If I say we're going to do your project, it gets done - and it gets done in a timely, clear, and honest process. I've been doing this for over twenty years, and I have customers whose parents' houses were projects back when we first started out. Our work is high quality, and it lasts, so a generation later we still have clients coming back to us for new work and we're being passed down in families like an heirloom. I'm very proud of our long list of five-star reviews online, because no one else in St. Louis has the kind of quality reviews that we do.

How I get the Job Done Right.

We have a perfect Better Business Bureau rating and 5-star ratings on Yelp, Facebook, Google, you name it. We use the best products, and the people on our crews are experts. They're quality professionals who work together as a team, some working together for almost twenty years. We have separate crews for roofing, siding, and windows, so each team really has tremendous expertise with their work.

Communication Counts

If you want a specific color or style for siding, roofing, or windows, I can give referrals to houses we've worked on all over the St. Louis area, so you can see how your finished project will look. I quote every job personally, with a site visit for every quote. It's as painless as possible and takes five minutes - unless you have five minutes of questions! We can communicate as much or as little as you want, depending on how involved you want to be or how many questions you have.

Cleanliness and Efficiency

Our crews show up and do the job right the first time, with phenomenal work on the job and during the clean-up process. We're fully insured and can provide all liability and other information up front before the job even starts.

Casey Exteriors just completed my new roof installation last week. I've worked with them before on smaller projects, but I can't believe how easy this process was for a full new roof through my insurance. Bill and his crew took care of things for me from start to finish! Not only was the process simple, the work is impeccable and everyone I spoke/dealt with could not have been nicer. Material was delivered on Thursday, and the job was completed on Friday. Their clean-up was so was like they were never even there (aside from the beautiful new roof, of course)! Very very pleased with them. Looking forward to some aesthetic projects with them!

I had originally hired a different company to replace our roof after storm damage. The other company kept giving us the run around, hadn't put us on the schedule. We finally gave up and looked for another contractor. I am SO glad that we found Casey Exteriors. Bill was a pleasure to work with. He responded promptly to any calls/texts, and he let us know in advance when he would be able to get the work done. He definitely wanted to make sure that we were happy with the work. I can't say enough good things about the roofing crew. They tore off and replaced the roof in one day. Afterwards, they cleaned up the area so thoroughly that I haven't found a single roofing nail or shingle in my yard, and none of my plants were damaged. If you need exterior work done, these are the guys to hire!

We had to replace out roof. Casey exteriors provided Excellent hassle free service. They made the roof repair easy and painless. Bill was very professional and polite when quoting. Bill was willing to work with what the insurance paid and no more. Office staff was also polite and courteous. We did call a few other roofers, but bill and his team had the best service hands down. Excellent service!! Thank you Bill and team. Would highly recommend to anyone needing a roof replacement or exterior work done.

I have used Bill Casey several times over the years, as has my extended family. He is very trustworthy and responsive. He really cares about his reputation and delivers to his customers expectations. He is also very reasonable in pricing, which is also important to know your contractor isn't raking you over the coals at any chance he gets. I have used other contractors for a couple of small jobs here and there along the way, and generally regretted not using Bill both times. He is top notch. Highly recommended contractor! Thanks for the nice job on the Windows today! They look amazing!

Bill recently put a new roof on for us and it was the easiest most professional job I have ever hired. It was so easy and the roof just looks great. I had a few questions along the way and his office staff was amazing. I'd recommend him to anyone. Bonus: he was willing to work for what the insurance paid and no more. (outside of the deductible of course). Thanks BIll!!

Bill and Gus' team are wonderful! They replaced our roof and garage door last summer and just did some exterior work on our house to help complete the sale of our home. Everyone is pleasant to work with, the work is done in a timely manner and always to the highest quality. We will be using Casey’s for all our future exterior needs and will be recommending them to anyone who needs work done to their home!
