Asphalt Shingle: Costs, Lifespan and Alternatives

Work on a North Beach roof starts with ground protection and a plan for where the debris goes. A typical North Beach re-roof runs one to three days depending on size, pitch and how much deck needs replacing.

Dry offshore winds reach North Beach through autumn and lift tabs and ridge caps in the direction roofs lap least well. Thermal cycling does the quiet damage in North Beach — hot afternoons, cool nights, materials working against their fixings.

A full replacement in North Beach needs a permit and a final inspection; small repairs generally do not. Structural work on a North Beach roof triggers a separate review beyond the roofing permit itself.

Two visits a year keeps a North Beach roof honest: clear valleys and gutters before the rains, check flashings after the first storm. Annual inspection on a North Beach property typically adds two to three years to the back end of a roof's life.

Nothing is left open overnight on a North Beach job — the deck is dried in the same day it is exposed. Flashing at every penetration is replaced rather than reused on a North Beach roof.

Tile on a North Beach property outlives its underlayment by decades, and the underlayment is the part doing the waterproofing. Low-slope sections on North Beach buildings need a membrane or coating system rather than shingle laid flatter than it is rated for.

We look at the deck from inside the North Beach attic as well as walking the roof; half the evidence is underneath. On a North Beach tile roof we lift field tiles in two or three places to date the underlayment, which takes about fifteen minutes.

The line that moves on a North Beach quote is deck repair, so it belongs in writing at a rate per sheet rather than as an allowance. Repair makes sense on a North Beach roof with life left and one localised failure; beyond that it is money spent twice.
