A roof is an assembly, not a covering
Almost every roofing quote a property owner reads is written as though the job were a single product: a shingle brand, a colour, a square-foot price. That framing is convenient for selling and it is the reason so many roofs installed in the last decade are already failing. What actually keeps water out of a building is an assembly of six or seven layers that have to work in sequence — deck, underlayment, ice and water barrier at the vulnerable edges, flashing at every interruption, the visible covering, the ventilation path underneath it, and the drainage that carries the load away.
Change any one of those and the others have to change with it. Putting a heavier tile or metal panel on a deck framed for asphalt is a structural question, not a preference. Sealing an attic tight without rebalancing intake and exhaust turns a well-insulated house into a condensation chamber that rots the sheathing from the underside. Running a synthetic underlayment under a metal panel without accounting for the temperature it will see is how you get an underlayment that has gone brittle before the panels are paid off.
We specify the whole assembly before quoting the covering. It makes the proposal longer to read and it occasionally makes it more expensive than the cheapest bid on the table, and we would rather explain that up front than explain a callback in year four.
What we install
Roof Installation
New construction and full tear-off replacement, with deck inspection, underlayment, flashing detail and ventilation designed as one system.
Commercial & Flat Roofing
TPO, EPDM and modified bitumen on low-slope decks, with drainage design and detailing at every curb, drain and penetration.
Metal Roofing
Standing seam and exposed fastener panels, specified around thermal movement, coating system and the service life you are actually buying.
Shingle Roofing
Architectural and three-tab asphalt, read through wind ratings, impact classification and what the warranty document really covers.
Roof Maintenance Plans
Scheduled upkeep on a fixed cycle, so a twenty-dollar sealant failure never becomes a deck replacement.
Not sure which you need?
Describe the building, the slope and what the current roof is doing. Most of the time the right system is obvious once someone asks the right four questions.
Where roofs actually fail first
Field covering almost never fails first. The middle of a slope, away from any interruption, is the easiest part of the roof to get right and the last part to give up. Failures start at the interruptions — the places where the roof stops being a plane and has to turn a corner, wrap an obstacle or hand water off to something else.
| Layer | What it does | How it typically fails |
|---|---|---|
| Deck | Carries the load and gives every layer above it something to fasten to. | Soft or delaminated sheathing gets covered rather than replaced, so fasteners never reach full withdrawal strength. |
| Underlayment | The secondary water barrier for wind-driven rain that gets past the covering. | Felt left exposed too long before dry-in, or a synthetic run under a system that cooks it past its rated temperature. |
| Ice and water barrier | Self-adhering membrane at eaves, valleys and around penetrations. | Omitted to save a few hundred dollars, or stopped short of the interior wall line where the damming actually happens. |
| Flashing | Manages the transition at walls, chimneys, valleys, curbs and vents. | Old flashing reused on a new roof, or a bead of sealant substituted for a step-flashed detail. The single most common source of leaks. |
| Covering | Sheds bulk water and takes the UV, hail and wind load. | Under-fastened for the wind zone, or a product rated for a slope steeper than the one it was installed on. |
| Ventilation | Moves air from intake at the eave to exhaust at the ridge. | Exhaust added without matching intake, so the ridge vent pulls conditioned air out of the living space instead of air from the soffit. |
| Drainage | Carries water off the assembly and away from the foundation. | Undersized on low-slope roofs, or blocked at a scupper nobody has looked at since the building opened. |
How a nationwide installer stays accountable
Working across the country introduces a real problem that local companies do not have: the crew standing on your roof is not the person who sold you the job. Plenty of national roofing brands solve that by not solving it — they broker the lead, hand it to whoever bid lowest, and disappear from the relationship. We run it the other way.
- The specification is written before the crew is assigned. Materials, fastening pattern, flashing details and ventilation math are fixed in the proposal, so the crew is executing a document rather than improvising a price.
- Photographic documentation at dry-in. The most important hour of any roof is the one when the deck is bare and the underlayment is going down, and it is the one hour nobody ever sees. It gets photographed and it goes in your file.
- Local code drives the assembly, not a national default. Wind uplift requirements, ice barrier extents and ventilation ratios vary enormously by jurisdiction. The assembly is written to the code that applies to your building.
- One written scope, one price. Deck replacement is quoted at a per-sheet rate in the original proposal, so the classic mid-tear-off surprise is a number you already agreed to.
Getting a bid that is far cheaper than the others? Read it for what it leaves out rather than what it includes. The usual omissions are new flashing, ice and water barrier, drip edge, deck replacement allowance and haul-away. A quote can be thirty percent lower and still be the more expensive roof once those come back as change orders.
