The ultimate defense against leaks. Simmons Roofing waterproofs roofs across Southeast Missouri with advanced materials and techniques that seal your roof and keep water where it belongs — outside.
Roof waterproofing uses advanced materials and techniques to seal your roof and prevent leaks and water damage. It adds an extra layer of protection — especially valuable on flat and low-slope roofs, and around the vulnerable points where water tends to find its way in. Simmons Roofing waterproofs roofs across Southeast Missouri for lasting, watertight protection.
Whether it's a high-quality protective coating, sealed seams and flashing, or a full flat-roof waterproofing system, we reinforce your roof exactly where it needs it most — keeping water out and extending the life of the roof.
As a family-owned, licensed, insured, and bonded company, we help you stop leaks before they start. Every job begins with a free, no-obligation estimate.
Here's how we add watertight protection to your roof.
Advanced sealants that add a durable, watertight layer.
The vulnerable points where leaks start, locked down.
Specialized waterproofing for flat and low-slope roofs.
Water stopped before it ever gets into your home.
Every roof has vulnerable points — seams, flashing, penetrations, and low spots — where water works hardest to get in. Waterproofing reinforces exactly those areas, adding a layer of protection that a standard roof surface alone doesn't provide.
It's especially valuable on flat and low-slope roofs, where water sits instead of running off, and on aging roofs that could use an extra line of defense to squeeze more years out of them.
A waterproofed roof means fewer leaks, less water damage, better energy efficiency, and a longer roof life — protection you'll be glad you have the next time a storm rolls through.
Every waterproofing job is done to seal out water for good.

Roof waterproofing uses advanced coatings and sealing techniques to create a watertight barrier that prevents leaks and water damage. It reinforces the vulnerable areas of your roof and adds an extra layer of protection beyond the roofing surface itself.
Flat and low-slope roofs benefit the most, since water sits on them rather than running off. Aging roofs and any roof with leak-prone areas — lots of seams, flashing, or penetrations — also gain a lot from waterproofing.
No. Waterproofing is an added layer of protection applied to your existing roof, not a replacement. It's a cost-effective way to reinforce and extend the life of a roof that's still in serviceable shape.
It can. Many protective roof coatings are reflective, which helps bounce away heat, and sealing gaps and seams reduces air and moisture intrusion — both of which can improve your home's energy efficiency.
It varies by the product and your roof's condition, but a quality waterproof coating adds years of extra protection. We'll recommend the right system for your roof and explain what to expect during your free estimate.
