Codes change, and the San Francisco Department of Building Inspection applies the version current on the day the permit issues, which is one reason a Mission District quote should state the assembly being installed. Work in Mission District is inspected as well as permitted — the San Francisco Department of Building Inspection signs off the finished assembly, not just the application. As a rule, historic districts near Mission District may restrict covering type and colour, which is worth confirming in advance of materials are ordered. Permit fees in Mission District are a small part of the work and a large part of what protects the owner at resale.

Roof surface temperatures in Mission District routinely run well above the air reading, and every material on the roof covering feels it. As a rule, dust and grit settle on Mission District roofs through the dry months and wash into the drainage the first time it rains. Mission District gets its wet weather in a handful of concentrated winter storms, which means drainage that sat dry collecting debris has to move everything at once. We see it on Mission District roofs every week.

9Material Options for Mission District Roofs

Underlayment choice is what decides it more than covering choice on a Mission District tile roof covering, since that is the layer doing the waterproofing. On most jobs, composition shingle is the nearly all common covering in Mission District and the cheapest to replace, but it is also the soonest to show UV damage. Metal has grown in Mission District for its lifespan and reflectivity, though the fixing system has to allow for movement or the panels telegraph every fastener. This holds across San Francisco County. On most jobs, silicone coatings hold up well on Mission District roof coverings that pond slightly, where acrylic would not. On most jobs, reclaimed tile can be matched on Mission District heritage roofs, but the underlayment beneath it should always be new. Mixing materials across a Mission District roof is fine provided each section gets the system it needs and the transitions are flashed properly.

Sealant is the first casualty in Mission District; it shrinks, cracks and pulls away from every penetration within a few seasons. We see it on Mission District roofs every week. Attic temperatures in Mission District drive shingle life as much as the weather above does, which is why ventilation matters more here than the brochure suggests. A light-coloured covering in Mission District measurably lowers attic temperature and takes load off the air conditioning.
