Full tear-off re-roofing
Roof replacement in Long Beach, CA
Your roof has been patched more than once, the next storm worries you, and you want to know if it is time to replace it instead of repairing it again.

Roof replacement means tearing the old roof down to the decking, fixing what is underneath and installing a new roof system. It makes sense when repairs keep coming back or the materials are past their useful life. In Long Beach it typically runs $5.60 to $27.40 per sq ft depending on material.
Most roofs in Long Beach do not fail all at once. They wear out in pieces: a leak at a valley one winter, cracked shingles on the south slope the next, a soft spot near the eave after that. At some point the repairs cost more than they solve, and a new roof is the better use of the money.
Our crews handle the whole job ourselves, from the first look at your attic to the final magnet sweep of your yard. We replace asphalt shingle, clay and concrete tile, metal and low-slope roofs on houses, garages, apartments and small commercial buildings across Long Beach and nearby cities.
Repair or replace: how we make the call
We start by looking at the roof as a system, not one leak. On a shingle roof we check granule loss, cracking and how brittle the tabs are. On tile we look at the underlayment at the eaves and in the valleys, because that is usually what ends a tile roof. On flat roofs we look for blisters, open seams and ponding.
If the problems are isolated and the rest of the roof has years left, we tell you to repair it. If the damage is spread across slopes, or the roof has already been layered over once, replacement is usually the honest answer.
- Repeated leaks in different spots over two or three winters
- Shingles curling, cracking or shedding granules on several slopes
- Tile underlayment brittle or torn when we lift a few tiles
- Two layers of roofing already on the house
- Soft decking you can feel when walking the roof
What a full tear-off includes
A replacement is more than new shingles or tile. We strip the old roofing and underlayment to bare decking, then walk every sheet and replace rotted or delaminated wood. Fascia and rafter tails get checked while they are exposed, since dry rot at the eaves is common on older Long Beach homes.
Then we install new drip edge, underlayment, valley metal, pipe jacks and wall flashings before the finish material goes on. Old flashing is not reused. Ventilation is reviewed so the attic can breathe, and we haul away every load of debris.

Choosing the next roof for your house
The right material depends on the house, the roof slope, your budget and any rules that apply. A Spanish Revival home usually wants clay tile. A 1950s ranch often suits architectural shingles or standing seam metal. Low-slope additions and garages need a membrane system, not shingles.
We walk you through the choices with real samples and explain the tradeoffs in weight, cost and lifespan. Material warranties vary by product and manufacturer, and we show you what each one covers.
- Asphalt shingle: the lowest cost per square foot
- Concrete tile: tile look at a lower price than clay
- Clay tile: the classic choice for Spanish and Mission homes
- Metal: light, long-lasting and good for solar
- Low-slope membranes for flat sections and patios
When to call about roof replacement
Leaks every rainy season
If a new leak shows up each winter in a different room, the roof is wearing out as a whole.
Bald or curling shingles
Shingles that have lost their granules or curled at the edges no longer shed water well.
Sagging roof lines
A dip between rafters often means wet or broken decking that needs replacing.
Daylight in the attic
Light through the boards means gaps that rain and pests can also use.
Selling or buying a home
An old roof can hold up escrow, so many owners replace it before listing.
Adding solar panels
Panels last a long time, so the roof under them should be new before they go up.

Replacing roofs on Long Beach homes, old and new
Long Beach has every kind of roof. Craftsman bungalows in Bluff Heights and California Heights often carry their second or third shingle roof. The 1950s tracts in Los Altos and the Plaza are now on aging shingles or old concrete tile. Cliff May homes in Rancho Estates have low-slope roofs that need membrane systems. Near the water in Naples and Belmont Shore, salt air eats flashing and fasteners faster.
The City of Long Beach requires a building permit for re-roofing, and homes in historic districts such as Bluff Park or Rose Park can need extra review before a visible material change. California's Title 24 energy code can require a cool-rated roof on some re-roofs, so we check what applies to your roof before ordering material.

FAQ
Roof Replacement questions
How long does a roof replacement take on a typical Long Beach house?
Most shingle replacements on a typical house take two to four working days. Tile roofs and jobs with a lot of decking repair take longer. We give you a schedule before we start and cover the roof each night.
Can a new roof go over my old one during a roof replacement?
Sometimes a second shingle layer is allowed, but we rarely recommend it. A tear-off lets us see and fix the decking and replace all flashings. It also keeps the roof weight down.
Do I need to be home during the roof replacement?
No, as long as we can reach the side yards and an outlet. It is loud, so many people with pets or home offices plan around the tear-off day. We walk the finished job with you at the end.
What happens if it rains in the middle of a roof replacement?
We watch the forecast closely and only open as much roof as we can dry in that day. If rain comes in, the exposed areas are covered with underlayment and tarps. Most of our re-roofs are scheduled outside the heavy winter storms.
Is a permit really needed for a roof replacement in Long Beach?
Yes. The city requires a building permit for re-roofing and an inspection during the job. We pull the permit and schedule the inspection as part of our work.
