Roofing

Roof systems, tie-ins and flashing, performed by licensed roofing trades.

Roofing on a remodel is usually a junction problem: a new addition or patio cover meeting an existing roof, where the flashing detail decides whether the connection lasts.

In this climate the failures concentrate at penetrations, valleys and roof-to-wall transitions, where concentrated monsoon rain meets details that are dry most of the year. A Phoenix roof spends eleven months being cooked and a few violent afternoons being tested — the details that pass that test are designed, not improvised.

Tying a new roof into an old one starts with an honest assessment of the old one. Adding a decade-long addition onto underlayment that is already at end of life is a false economy the design stage exists to catch — sometimes the right scope includes renewing the adjacent roof plane while the trade is mobilised, and that is a decision to make deliberately, with the numbers visible.

Low-slope sections — common over Valley patio covers and additions — are their own discipline. Drainage has to be designed (slope, scuppers, overflow), because ponding water finds every shortcut. The flat-looking roof is the one where the drawing matters most.

This work is performed by licensed roofing contractors. Monarch designs the tie-in conditions, coordinates the trade, and sequences roofing so the structure is dried-in before the interior scopes that depend on it.

Monarch coordinates the full project scope, with specialty work performed by appropriately licensed trades where required.

What this covers

  • Roof tie-ins for additions and covered structures
  • Flashing at walls, valleys and penetrations
  • Underlayment and roof covering
  • Drainage, scuppers and slope
  • Repair of damage found during remodel work

Decided in design

Settled before anything is built.

These are the decisions the design and preconstruction stage resolves for this work — while changing the answer is a revision, not a demolition.

  1. Existing roof condition assessed before any tie-in is drawn
  2. Tie-in and flashing details designed at every new-to-old junction
  3. Low-slope drainage — slope, scuppers, overflow — engineered, not assumed
  4. Material match or deliberate contrast decided against the existing roof and any HOA constraints
  5. Sequencing so the building is dried-in before interior finishes begin

Questions

Answers we can give honestly.

The addition's roof is new — why are you talking about our existing roof?
Because the tie-in joins them into one system. Flashing a new roof into failing underlayment moves the leak to the joint. If the adjacent plane is near end of life, the honest options — tie in as-is, renew the plane while the trade is here — get priced side by side during design.
Why do monsoons find leaks that winter rain never did?
Volume and violence. A monsoon cell drops intense rain, often wind-driven sideways, in minutes. Details that shrug off gentle winter rain — a marginal scupper, a short flashing leg — get overwhelmed. Designing for the monsoon case is designing for the only rain that matters here.
Who performs the roofing work?
Licensed roofing contractors. Monarch designs the junctions and drainage, coordinates the trade, and holds the sequence so the roof is complete before the interior work it protects begins.
