Matching the material to the hillside and the home
A new roof installation starts with picking the right material for the home, the site, the budget, and the fire exposure, and we set out the real trade-offs rather than nudging you toward whatever sells easiest. On Portola Valley's wooded hills that conversation runs deeper than usual, because cedar belongs to the architecture yet asks for the most upkeep under shade and brings fire questions with it, slate and tile last for generations but cost and weigh the most, standing-seam metal sheds debris and stands up to fire and embers superbly, and a quality Class A composition delivers most of the protection at a friendlier price. The best choice turns on the home, the canopy above it, and how long you intend to stay.
Because we install the roof rather than push a single product, our recommendation rests on what genuinely fits your situation and your slope. A homeowner set on the cedar look atop a heavily shaded lot needs to grasp the maintenance that rides along with it, while another is better served by a metal or composition system that copes with the moisture and the embers at far less effort. We hand you the honest comparison, fire rating included, and leave the decision in your hands.
A full assembly, not just a surface
A new roof is much more than the material visible from the road. On new construction and additions we build the entire system from the deck up. We confirm the sheathing, lay quality underlayment, fit fresh flashing at every penetration and wall, run a clean drip edge, detail the eaves, valleys, and vents for ember resistance where the wildland edge calls for it, and finish with the roofing material itself. Every layer carries a job, and the roof only performs when all of them pull together, which on a fire-exposed hillside is not a refinement but a requirement.
Ventilation is engineered in from the outset, one of the biggest advantages of getting a roof right on a new build in this climate. Balanced intake at the eaves and exhaust at the ridge holds the attic near the outside temperature and, just as crucially on a foggy, shaded lot, keeps moisture flowing out instead of condensing on the underside of the deck and rotting it from within. Plenty of roofs in damp settings fail early because the original ventilation was wrong and the attic simply never dried. A new installation is the chance to set it right for the full life of the roof.
Permitted, fire-rated, and warranty-backed
A new roof ought to be done correctly, and on these hills that includes the fire code. We pull whatever permit the job requires, install to a Class A rating and to the manufacturer's specification so the material warranty actually holds, and have the work inspected as the code demands. Trimming any of those corners might shave a few dollars at the start, but it puts the warranty, the insurance, the fire performance, and the resale of the home in jeopardy, and that is not how we operate on a property where the roof matters this much.
Fitting the roof into the rest of a build is a real part of doing a new install well, especially on a custom home with a tight schedule and tricky access. The roof has to arrive at the right point in the sequence, once the framing and sheathing are ready and in step with the other trades, so the structure dries in without holding up the work that follows. We stay in touch with the homeowner and, where it applies, the general contractor or architect to time the install correctly rather than treating the roof as an isolated task dropped into the middle of a project. Getting that order right keeps the whole build moving and shields the new space from weather as early as possible.
Everything starts with a free, no-pressure consultation. We will look over the project, talk through the material options, the fire rating, and the trade-offs, and hand you a clear written estimate with the scope laid out. When the new roof is done, you receive the documentation, the manufacturer coverage, and our own workmanship warranty on top of it, so the roof over your new space is one you never have to give a second thought.
