Standing Seam & Metal: Costs, Lifespan and Alternatives

Two visits a year keeps a Presidio roof honest: clear valleys and gutters before the rains, check flashings after the first storm. Trimming branches back from a Presidio roof removes the debris that holds moisture against the covering.

Attic ventilation drives covering life in Presidio as much as the weather above the roof does. Presidio takes its rain in short heavy bursts, so drainage that sat dry collecting debris has to move everything at once.

Two warranties apply on Presidio work — the manufacturer's on material and the installer's on workmanship. Check the licence, liability cover and workers' compensation before any Presidio contractor starts work.

A Presidio property with two roof types gets two scopes, because a single lump sum hides what is being done. We inspect roofs in Presidio free of charge and put the findings in writing before any price is discussed.

Supplements are normal once a Presidio roof is opened up, and they should be raised with evidence attached. Policies on Presidio properties pay for sudden damage and not for age, so the report has to separate the two.

Emergency work in Presidio costs more than planned work, for the obvious reason that nobody chose the timing. Active leaks in Presidio get same-day or next-day attention; planned work is scheduled around the weather.

Repair makes sense on a Presidio roof with life left and one localised failure; beyond that it is money spent twice. Cost on a Presidio roof comes down to size, pitch, how many layers come off and the state of the deck underneath.

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