A full roof replacement removes your old roof down to the deck and installs a complete new system: underlayment, flashing, shingles or metal, and ventilation. Our primary system is architectural asphalt shingle, always a 30-year shingle and never cheap 3-tab. We also install standing-seam metal, slate, and residential TPO. Asphalt replacements start around $9,000, and most Lake Saint Louis area roofs land between $20,000 and $25,000. These are estimates, not binding quotes.
You don't need to book a sales visit to find out where your home lands: enter your address, we measure your roof from satellite imagery, and you get a real estimate range in minutes. We serve Lake Saint Louis, St. Charles, Wentzville, St. Peters, Bridgeton, Wright City, Warrenton, Troy, Chesterfield, Ballwin, Town & Country, Creve Coeur and Maryland Heights and the surrounding St. Charles County towns.
When do you need Roof Replacement in Lake Saint Louis?
An honest contractor should talk you out of work you don't need. We recommend Roof Replacement when we see:
- Shingles are cracked, curling, or missing across the whole roof
- Your roof is past 20 years and has never been replaced
- Repeated leaks in more than one spot
- Bald patches and granules collecting in the gutters
- An insurer or adjuster called the roof a total loss after a storm
If none of these apply, we will tell you so. We would rather earn a repair today than sell a replacement you do not need.
What LSL Roof Replacement actually includes
No good-better-best games. This is what is in every Roof Replacement job we do across Lake Saint Louis:
Tear-off to the deck
We strip the old roof down to the decking so nothing is shingled over and hidden problems like rotten decking get caught and replaced.
Synthetic underlayment and ice-and-water shield
A full underlayment layer plus ice-and-water shield in the valleys and at the eaves where leaks start.
30-year architectural shingles
Our primary system is a 30-year architectural asphalt shingle, never 3-tab, installed by a CertainTeed Master Craftsman crew.
New flashing and proper ventilation
Fresh flashing at every penetration plus balanced attic ventilation, including solar slant-back vents on request, so the new roof lasts its full life.
