Shingle roofs are simpler than tile, but a few things still swing the number:

• Roof size and pitch
• How many layers come off
• Soft or delaminated sheathing found after tear-off
• Self-adhering underlayment in valleys, at eaves and around penetrations
• Vents and flashing, plus any low-slope sections that shouldn't carry shingles at all
• Shingle line and color, and HOA rules if you have them

How much a shingle roof really costs goes deeper on these. For your own house, the estimator gives a quick range and a free inspection settles it.

Maryvale: 1950s trusses, sheathing to watch

Maryvale grew from 1954 to more than 30,000 homes between 35th and 91st Avenues, I-10 to Camelback. Long framed with manufactured trusses, which gives these houses simple, regular roof planes that shingle well. On a house this age, though, we look hardest at the sheathing along the eaves and in the valleys once the old roof is off. We tear off to the deck, replace what's soft, and start clean.

Many of these houses also have a flat patio roof or carport tied into the shingled slope. Shingles stop where the pitch gets too low to shed water, and the flat part gets its own system, usually foam. The joint between the two is a common leak point, so we flash it as its own detail instead of running shingles past where they belong.

Felt fails where the water goes

Older Phoenix shingle roofs were laid over felt. Heat cooks the oils out of it until it turns brittle, and it cracks first in the valleys and along the eaves, where water from two planes collects. That's where we put self-adhering membrane. It bonds to the deck, so there's no nail hole at the bottom of a valley for water to find. Why old roofing felt fails in high-water areas and what makes self-adhering underlayment hold so well explain both halves of that.

Vents, valleys and monsoon downpours

A monsoon cell can drop a lot of water on a Phoenix roof in a short time, and a valley carries all of it. A dryer vent or plumbing stack sitting in that path acts like a dam. When we find one, we move it onto a clean field of roof between trusses and flash it properly instead of counting on a seal. Attic ventilation gets the same attention, because balanced intake and exhaust keeps heat from cooking the deck during a 110 degree stretch. UV and heat also wear the granules off older shingles, and once the asphalt is exposed the shingle ages fast. Granules piling up at the downspouts are a sign the roof is near the end.
