Oakville roof replacement, at a glance
Most Oakville homes were built from the 1960s through the 1980s, and many of them are now on their second or third roof. If yours has two layers of shingles, curling edges or leaks that keep coming back, it's probably time to talk about replacement. Call (314) 429-6000 any hour.
Why Oakville roofs wear out the way they do
Oakville is mostly ranches, split-levels and two-story homes on generous lots, many of them backing up to trees or to the bluffs along the Mississippi. Back in the day it was common to roof right over the old shingles to save money. Now we find those second layers holding heat against the deck, hiding rot and adding weight the framing was never meant to carry.
Original decking from that era is often plank boards or thin plywood. Years of small leaks and attic condensation soften it near the eaves and around chimneys. You can't see that from the driveway. You find it when the old roof comes off, which is why we check every section of deck during tear-off and replace what's damaged before anything new goes down.
What a replacement includes
Shingles are the part you see. Everything under them decides how long the roof lasts.
- Complete tear-off down to the deck, every layer
- Damaged decking replaced and the deck re-nailed where needed
- Ice and water barrier at the eaves and in valleys
- Synthetic underlayment over the rest of the deck
- New drip edge, pipe boots and step flashing
- Ventilation checked and corrected
- Owens Corning architectural shingles and matching ridge cap
- Magnetic sweep of the yard and driveway for nails

Is replacement the right call?
Not every old roof needs to come off. If the shingles still lie flat and the problem is a single leak at a vent or chimney, a roof repair in Oakville may be enough. We will tell you which one makes sense and put the reasons in writing. If a recent storm is the reason you're looking, start with our Oakville storm damage page, because insurance may cover part of the cost.
