Choosing a Shingle for Long Beach UV Load — Budget Planning

What moves the number on an asphalt shingle roof in the Harbor Area, before anybody puts a figure on paper.

Price is the first thing anybody wants and the last thing most contractors will commit to. The working figure for an asphalt shingle roof in the Harbor Area is $5.50 to $9.00 a square foot installed, and the rest of this explains what moves it, because the same roof can differ by half again depending on things you can check yourself before anyone quotes.

What you are actually paying for

Layer count, deck condition and roof complexity move the figure more than the shingle you choose. Tearing off two existing layers instead of one adds disposal and labour before a single new shingle goes down, and a cut-up roof with several valleys and dormers takes far longer per square than a simple gable.

Where quotes diverge

Deck repair should be priced per sheet in writing before work starts, because it is the one item nobody can size until the covering comes off. The starter course and the drip edge are where cheap work shows first. A starter strip laid the wrong way round, or an eave with no metal under the first course, will wick water back into the fascia no matter how good the shingles above it are. It is also the line that most often separates two quotes that looked identical on page one.

How the Harbor Area changes the figure

Humidity stays high, salt is constant, and industrial fallout settles on top of both. Flat and low-slope roofs dominate the commercial stock here, and a membrane that would give twenty years in a dry inland setting can give noticeably less with that combination working on it every day. Much of the building stock is older commercial and industrial with large low-slope areas, parapets, and rooftop plant that gets walked on regularly.

What we look at before quoting

Granule loss across the field, and how much is sitting in the gutters
Curling, cupping or cracking, particularly on the sun-facing slopes
Nail placement and whether shingles have begun to back off the deck
Valley construction, and whether it is woven, closed-cut or metal-lined
Flashing at every wall, chimney, skylight and pipe penetration
Deck condition underfoot, checked by walking rather than by eye
Attic ventilation, both intake at the eave and exhaust at the ridge

Common questions

Can I get an accurate price without an inspection?

You can get a range. You cannot get a price, because nobody knows the deck condition until the covering comes off, which is why the per-sheet repair rate belongs in the estimate.

Is financing worth it on a roof?

It depends on the alternative. Deferring a failing roof through another wet season usually costs more in interior repairs than the finance charge would have.

The honest summary

Shingle roofs rarely fail suddenly. They give years of warning through granule loss and edge curl, and the difference between a planned replacement and an emergency one is usually whether anybody was looking. In the Harbor Area the thing to watch is membrane condition around rooftop plant, parapet terminations, and every drain and scupper on the roof.
