Installing a new roof is one of the bigger calls a property owner makes, and getting it right pays off for decades. A properly installed system holds up against the weather, keeps the structure sound underneath it, and works with your insulation and ventilation to lower energy costs. It also does wonders for curb appeal and resale value. Get it wrong, though, and you're looking at leaks, wasted energy, and repair bills that keep piling up, usually worse the longer they go unaddressed. Cornerstone Roofing Solutions brings years of hands-on installation experience to every Oxford, MS project we take on. Our focus stays on getting the roof right from day one: durable materials, correct installation sequencing, and performance that holds up long after the crew has left.
Reasons Property Owners Need a New Installation
Not every roof installation happens for the same reason. Knowing which situation fits your property helps us plan the right approach and material choices for your project.
New Construction
We work alongside builders and homeowners on new builds, putting in complete roofing systems that fit the building's design, drainage layout, and attic ventilation plan from day one.
Complete Tear-Off and Replacement
Once an old roof has run its course, a full tear-off gives us the chance to upgrade materials, fix any ventilation issues that were baked in originally, and put on a system built to current standards.
Room Additions and Extensions
New garages, room additions, and other expansions need roofing sections that tie into your existing roof correctly, matching pitch, drainage, and appearance so the finished result looks like one roof, not two.
Upgrading to a New Material
If you're moving up from worn asphalt to metal, tile, or another specialty material, a fresh installation lets us build the structure and details around exactly what that new system needs to perform well.
The Layers That Make Up Your Roofing System
A roof that's done well isn't just one layer of shingles. It's several components installed in a specific order, each doing its own job. Here's what actually goes into a system built to last, and why skipping a layer is where shortcut installs go wrong.
| Layer | Material | Purpose |
|---|---|---|
| Deck | OSB or Plywood Sheathing | The structural base everything else attaches to, spreading the roof's load evenly across the framing below. |
| Ice and Water Barrier | Self-Adhering Membrane | Installed at eaves, valleys, and penetrations to keep moisture out during ice dam formation and heavy wind-driven rain. |
| Underlayment | Synthetic or Felt | A backup moisture barrier across the whole deck, protecting the structure both mid-installation and if the top layer is ever compromised. |
| Starter Strip | Pre-Cut Shingles or Tape | Seals the roof's edge and gives the first course of shingles or panels a clean, straight line to align against. |
| Field Material | Shingles, Metal, or Specialty | The main weather-facing surface, responsible for shedding rain, holding up against wind, and giving the roof its finished look. |
| Flashing | Galvanized or Aluminum Metal | Covers every joint, valley, edge, and penetration where the main roofing material alone can't keep water out. |
| Ridge Ventilation | Ridge Cap with Vent | Lets built-up heat escape the attic continuously, keeping temperatures in check and preventing the moisture buildup that rots decking. |
How We Approach Every Installation
Every roof we put on follows the same disciplined order, with each layer checked and secured before the next one goes down. Nothing about a Cornerstone installation gets skipped or rushed.
Getting the Site Ready
We cover your landscaping, driveway, and other exterior surfaces before work starts and set up debris collection to keep the property clean. Permits are pulled ahead of time, and we walk you through the project timeline before the crew shows up.
Checking the Deck
Old material comes off where needed, and we go over the deck carefully for damage, soft spots, or weak fastening. Anything we find gets corrected before any waterproofing goes down.
Putting Down the Waterproofing
Ice and water barrier goes in at every vulnerable spot, followed by synthetic underlayment across the entire deck. We overlap and seal these layers properly at every edge and penetration.
Installing the Flashing
Every piece of metal flashing goes in and gets sealed before we touch the field material. Getting this sequence right means water is directed away from every joint and penetration without leaning on caulk to do the job.
Laying the Roofing Material
Shingles, metal, or specialty material go on following the manufacturer's exact nailing pattern, exposure, and alignment. We check each course for level and proper interlock before moving to the next.
Finishing Ridges, Vents, and Edges
Ridge ventilation goes in to keep attic airflow moving, ridge cap material gets applied, every edge is finished off, and gutter aprons are secured so the whole perimeter is sealed up tight.
Final Walkthrough and Cleanup
We do a final quality check against our own standards and local code, then clean the property thoroughly, magnetic sweep included, and hand over all your documentation before we call it done.
