Decks Inspected Before Material Goes Down
Roof Installation in the St. Louis metro for new construction, additions, and properties requiring full deck-up installation
New roof installation starts with what you can't see from the ground. Roofing STL, LLC approaches installation as a deck-up process—inspect the sheathing, replace rotted sections, confirm ventilation design, then install the material that will sit on top. You're in older St. Louis area neighborhoods like Florissant and Ballwin where aging decks require assessment before any new shingles or membrane go down. Skipping that step means new material fails early because it's covering compromised structure.
The installation process includes deck inspection and replacement of rotted sheathing as part of the standard scope, not an upsell added after tear-off when the damage becomes visible. This applies to both residential and commercial properties across the metro.

Installation involves tearing off old material if present, inspecting or installing sheathing, ensuring proper ventilation on residential attics, and then laying the new roof system according to manufacturer specifications. On commercial flat roofs, this includes confirming insulation condition and drainage slope before the membrane goes down.
After installation, you'll see a roof surface with uniform appearance, no lifted edges or gaps at seams, and properly integrated flashing at every penetration and transition. The structure underneath will be solid, ventilation will function as designed, and the new material will perform as expected because it's not trying to compensate for deck problems that weren't addressed.
Deck inspection and sheathing replacement prevent the hidden failures that happen when new material covers rotted wood or inadequate structure. That approach has been applied across 2000+ roofs throughout the St. Louis metro, and it's the same whether the project is a residential installation in Webster Groves or a commercial roof in Clayton.
Common Installation Questions
New roof installation brings up questions about process, timing, and what's included in the scope. Property owners want to know what happens if problems show up once old material comes off.
What happens if you find rotted sheathing during installation?
Rotted sheathing gets replaced before new material is installed—that's part of the deck-up approach, and it prevents new roofs from failing prematurely because they're sitting on compromised structure.
How long does a typical roof installation take in St. Louis?
Residential installations usually finish in one to three days depending on size and complexity, while commercial flat roof installations vary based on square footage and whether insulation or slope correction is needed.
Do you install roofs year-round or only in certain seasons?
Installation happens year-round in St. Louis, though extreme cold affects material performance and summer heat changes how crews work—scheduling depends on current roof condition and weather windows.
What roofing materials do you install for residential properties?
Asphalt shingles are the most common residential material in the metro, with metal and tile used in specific applications—material choice depends on building design, budget, and expected lifespan.
Is deck inspection included in every installation quote?
Yes, deck condition gets assessed before the quote is finalized so there are no surprises once tear-off begins—that's how you avoid the patch-and-pray approach that turns into callback work within a season.
Roofing STL, LLC handles installation projects across the metro with a focus on what's underneath the material, not just what shows from the street. Schedule an on-site assessment to review your property's deck condition and discuss material options that match your building and budget.
