Gutters are priced by the linear foot of eave they run along. A single-story ranch needs about 126 feet, which puts seamless aluminum with removal and downspouts at roughly $1,200–$2,400.

Most fascia and soffit jobs are a rotten section near a gutter, priced around $900 for 30 feet. Replacing the whole roof edge of a ranch house is closer to $3,000–$6,000.

Flashing is priced per location, not per square. Replacing it around one chimney or skylight usually runs $300–$800, and the chimney is where quotes climb, because the masonry is part of the job.

The price of a leak repair depends on where the water gets in. A clogged gutter or cracked vent boot costs a few hundred dollars; a valley or chimney can cost several times that.

Mobile home roofs cost less per square foot than site-built roofs because they are low, single-story and simple. Width and material decide most of the price.

The membrane chosen moves a flat roof's price more than its size does. EPDM rubber and TPO start near $4 per square foot; the top of every range comes from access, tear-off and what is found under the old roof.

Clay tile and slate often outlast the underlayment beneath them. That is why many "tile roof replacements" reuse the tiles and replace only what is underneath, at a fraction of the price of a new roof.

Small roofs cost more per square foot than house roofs because the trip, setup and disposal are spread over fewer squares. The roof area, not the garage's floor size, decides the price.

Most asphalt re-roofs land between $9,500 and $22,500. The number for one house comes from three inputs: roof squares, price per square, and the lines the base price leaves out.

A 1,500 sq ft house does not have 1,500 sq ft of roof. On a common 6/12 with normal eaves it has closer to 1,900, and every quote is priced on the larger number.

Decking is the one roofing cost nobody can count before the old shingles come off. The per-sheet rate is rarely the problem; a contract without one is.

Most state roofing tables are bands somebody eyeballed. This one is arithmetic on a published number: BLS mean pay for roofers in each state, applied to the 60% of a re-roof that is labor.

Standing-seam steel costs roughly one and a half to two times architectural shingles up front and lasts about twice as long. How long the owner stays decides more than the price per year.
