Roof Installation

A roof installation is a full roof replacement. We strip the old roof down to the wood deck, fix what we find, and build a new roof from the deck up. Tradition Roofing Company has installed new roofs across the East Bay since 2007. We work in asphalt shingle, tile, flat and low-slope, and metal.

What is included in a new roof installation?

A new roof is much more than the shingles you see from the street. It is a full system, and each layer has a job. We remove the old roof first, then check the wood deck underneath. We replace any boards that are soft, rotted, or sagging. Next we lay new underlayment, the water barrier that guards the wood if wind or rain pushes water past the surface. We set new flashing at the valleys, walls, chimneys, and vents, because most roof leaks start at these joints, not in the open field. We add or repair attic venting so heat and damp air can escape. Then the new roof surface goes on, whether that is shingle, tile, standing-seam metal, or a flat-roof membrane. A new roof in California needs a building permit, and we pull it and build to code.

What is the difference between a reroof and a full replacement?

People use the words in different ways, so it helps to be clear. A reroof sometimes means laying a new layer over an old one without a tear-off. A full replacement, which is what we almost always do, means stripping the roof down to the deck and building it back up. A full replacement costs a bit more and takes a little longer, but it is the honest, lasting choice. It lets us inspect the deck, fix hidden rot, replace the flashing and underlayment, and give you a roof that starts fresh instead of hiding old problems under a new surface.

Which roofing material is best for a new roof?

The best material depends on your home, your budget, and how long you want the roof to last. We do not push one product. We look at your home and walk you through the honest trade-offs.

Asphalt shingle is the popular pick and the easiest on cost. A good architectural shingle roof looks clean and lasts many years, which is why most homes wear it. Metal sheds rain fast and stands up to wind and sun, so a standing-seam metal roof can last for decades and needs little care. Tile gives a classic look and a very long life, though it weighs more, so the frame has to carry it, and it costs more up front. Flat and low-slope roofs, common on additions, garages, and some modern homes, need a sealed membrane instead of shingles, because water sits and drains slowly on them. Once we see your roof and hear your plans, we help you match the material to your home and your budget.

How do you install a new roof?

We install a new roof in clear, tidy steps, and we keep your yard protected the whole time. First we tear off the old roof down to the deck and haul the old material away. Then we inspect the bare wood and replace any damaged boards, since a new roof is only as sound as the deck beneath it. Next we roll out fresh underlayment and set the flashing at every joint. After that we install your chosen roof surface, shingle, tile, metal, or membrane, and finish the edges, valleys, and ridge. Last we clean the whole site, run a magnet over the lawn and driveway for stray nails, and walk the finished job with you. We work to California code the whole way, including Title 24 energy rules where they apply, so your roof passes inspection.

Why do the deck and ventilation matter on a new roof?

The deck and the venting decide how long your new roof lasts, even though you never see them. The deck is the wood layer the whole roof sits on. If we cover soft or rotted boards, the new roof will sag and fail early, so we replace bad wood before anything else goes on. Venting matters just as much. Good intake and exhaust vents let hot, damp attic air escape instead of baking the underside of the roof and rotting the deck from below. In the wet East Bay winters, that trapped moisture is a real problem. California's Title 24 energy code can also call for cool-roof materials or added ventilation on some homes, and we build to meet it.

How long will a new roof last?

A new roof should last for decades when it is installed right and vented well. The exact number depends on the material. Asphalt shingle roofs commonly last around 20 to 30 years. Metal roofs can last 40 years or more. Tile can last the longest of all, often 50 years or more, since the tile itself does not wear the way shingles do. East Bay weather still matters. The coastal marine layer and wet winters keep roofs damp, and hot, dry summers age the surface, so good venting and yearly checks help any roof reach its full life. Installing the right material for your home is the first step toward a roof that lasts.

Best Roof Installation in San Leandro

We are based in San Leandro and install roofs across the East Bay. Local weather shapes how we build. Wet winters and the coastal marine layer keep roofs damp, so strong underlayment, tight flashing, and good venting matter here more than in a dry climate. Dry, sunny summers bake the surface year after year. In the hills near the wildland edge, a fire-smart roof is worth the thought. We have installed roofs on East Bay homes since 2007, so we know what a local roof goes through and how to build one that lasts.
