1Choosing a Covering in Tenderloin

Coatings suit Tenderloin buildings with a sound deck and a tired surface — they buy years, but they do not fix water already trapped in the insulation. Cool-rated coverings are worth specifying in Tenderloin even where code does not require them. Lightweight tile gives Tenderloin owners the look without the structural upgrade older framing would otherwise need. Realistically, synthetic composite has become a credible option in Tenderloin where the look of slate or shake is wanted without the weight or the fire risk. Mixing materials across a Tenderloin roof is fine provided each section gets the system it needs and the transitions are flashed properly.

Granule loss in the gutters is the earliest honest signal on a Tenderloin shingle roof, and it shows up years in advance of a ceiling stain does. A proper Tenderloin inspection starts at the flashings, not the field. Chimneys, vents, skylights and the swamp cooler curb fail long before the covering does. Put simply, a Tenderloin inspection should end with a written report and photographs, not a verbal summary and a price.

Ask any Tenderloin roofer what happens if the deck is worse than expected, and get the answer ahead of the covering comes off. Itemised scope, documented price and a documented warranty are the minimum on any Tenderloin job. Check that the Tenderloin crew doing the work is employed by the company quoting it. A Tenderloin contractor who will not put the assembly in writing is not quoting the same project as the one who will.

Deck replacement on a Tenderloin project is unknown until the tear-off, which is why it belongs in the contract as a per-sheet rate. Budgeting a Tenderloin replacement a few years out costs nothing and removes the pressure of choosing a contractor during a storm. Repair makes sense on a Tenderloin roof with life left and a localised failure, and nowhere else.

5Maintaining a Tenderloin Roof

Trimming back branches over a Tenderloin roof removes the debris that holds moisture against the covering and shortens its service life. This holds across San Francisco County. Put simply, moss on a shaded Tenderloin slope should be treated rather than scraped, since scraping takes the granules with it.
