Realistically, dry offshore winds reach Potrero Hill through autumn, lifting shingle tabs and ridge caps in the direction roof coverings are least lapped to resist. Realistically, attic ventilation on a Potrero Hill property is not optional — trapped thermal load cooks the covering from underneath. Expansion and contraction loosens fixings on Potrero Hill roofs long before the material itself gives out. On most jobs, low-slope sections in Potrero Hill hold thermal load worst, which is why coatings and reflective membranes pay for themselves here. San Francisco County is no different.
As a rule, concrete tile suits Potrero Hill buildings designed for the weight; laying it on framing that was not is a structural question first. On most jobs, silicone coatings hold up well on Potrero Hill roofs that pond slightly, where acrylic would not. Put simply, architectural shingle outperforms three-tab on a Potrero Hill roof for a modest extra cost and a meaningfully longer life.
9Which System Fits a Potrero Hill Property
Composition shingle is the most common covering in Potrero Hill and the cheapest to replace, but it is also the earliest to show UV damage. We see it on Potrero Hill roofs every week. Mixing materials across a Potrero Hill roof covering is fine provided each section gets the system it calls for and the transitions are flashed properly. Realistically, metal has grown in Potrero Hill for its lifespan and reflectivity, though the fixing system has to allow for movement or the panels telegraph every fastener. As a rule, underlayment choice matters more than covering choice on a Potrero Hill tile roof, since that is the layer doing the waterproofing. On most jobs, coatings suit Potrero Hill buildings with a sound deck and a tired surface — they buy years, but they do not fix water already trapped in the insulation. Reclaimed tile can be matched on Potrero Hill heritage roof coverings, but the underlayment beneath it should always be new.
As a rule, potrero Hill gets its rainfall in a handful of concentrated winter storms, which means drainage that sat dry collecting debris has to move everything at once. Sealant is the first casualty in Potrero Hill; it shrinks, cracks and pulls away from every penetration within a few seasons. We see it on Potrero Hill roofs every week. Attic ventilation on a Potrero Hill property is not optional — trapped heat cooks the covering from underneath.
