For metal roofing, the roof is inspected and photographed first, and the scope and price come in writing.
One call to (855) 512-1072 reaches Roofers Hotline for metal roofing in San Francisco and 5 towns across Marin and San Mateo counties. Calls are answered 24 hours a day and every estimate is put in writing before work starts.
Older roofs are the norm here, where Census estimates put 77% of homes inside the city limits before 1980, and estimates cover repair and replacement.
The estimate names which panel type fits your roof and why. Standing seam hides the fasteners, while exposed-fastener panels use screws through the face. With a Low hail band for the metro, the choice comes down to budget, roof shape and how long you plan to stay. Call to compare both in writing.
Metal needs underlayment made for it, and the estimate lists the product. The metro averages 22.9 inches of precipitation a year in the 1991 to 2020 normals, so the layer under the panels matters for the damp months. Call and ask which underlayment is priced for your roof.
Edges and joints are where water gets in, so the estimate itemizes trim, ridge, eave and valley work. On homes built around the 1945 median, the edges often need attention before new panels go on. Call to have each detail priced and written down.
Snow guards are included only where snow loads require them. The metro has no freeze days and no measurable snowfall in the 1991 to 2020 climate normals, so most roofs here will not need them. Call, and the written estimate will say plainly whether yours does.

Roofers Hotline books metal roofing in San Francisco, and the written estimate before any work starts covers the panels, the underlayment, the trim and flashing details, and how the panels are fastened. In a city where the median home was built in 1945, the existing roof deck and edges are often older than the roof on top of them, so the visit looks at those first. Call 24 hours a day to book the inspection, then ask for the written estimate so you can compare the scope line by line before you decide.
San Francisco has almost no hail. NOAA's storm records since 2015 show no hail of one inch or larger in the county and one damaging thunderstorm wind event, and the largest hail on record was half an inch. So a metal roof here is chosen for long life and wind, not for impact. The latest federal disaster declaration, on April 3, 2023, was for severe winter storms, straight-line winds, flooding, landslides and mudslides, which is why the written estimate spells out edge details and fastening. Call to have those items priced.
The visit itself is covered under what roof repair includes, which serves 168 ZIP codes.

Say you are replacing a roof you plan to keep 40 years or more. In a city where 77 percent of homes were built before 1980, that decision often comes with older framing and a deck that needs a look first. The same applies to high wind exposure and to low-slope sections where shingles fail early. Photograph what you see from the ground, and do not climb onto the roof. Call, and the inspection will confirm what the roof needs.

Why call
Book metal roofing whenever your roof is due, because San Francisco has no freeze days and almost no snow in the 1991 to 2020 climate normals, so winter does not close a window for the work. Housing age is the better reason to call: with a median build year of 1945 and 77 percent of homes built before 1980, expect the inspection to check the deck and edges as well as the roof surface. You get the inspection, a written estimate before any work starts, and then the installation. Call to set it up.
