Fast, Reliable Roof Installation Across Lynwood
Roof installation in Lynwood usually means a full tear-off, not a quick overlay. The housing stock here runs heavily to 1940s and 1950s stucco tract homes with original composition shingles or wood shake roofs that are decades past their lifespan, plus aging apartment buildings along Long Beach Boulevard with flat roofs carrying multiple layers of old material. A proper Roof Installation on these structures starts with getting down to the decking and seeing what is actually there. Our crews know Lynwood, we know what these roofs hide, and we give you a written price before any work starts. Call (213) 521-8272 and a live person answers.
Why Mercer Roofing Co Los Angeles Is Lynwood’s Preferred Roof Installation Company
Homeowners in Lynwood call us because we treat the person answering the door with the same seriousness as the roof going on the house. Every technician who comes to your home is background-checked, identity-verified, and arrives in a clean, marked uniform with a photo ID badge. Before they arrive, we send you their name and photo. That is the Threshold Verified standard, and every Mercer Roofing location is held to it. For parents home alone with young kids, or older homeowners who want proof of who is at the door, that matters as much as the shingle brand.
We have torn off enough roofs near Lynwood Park, along Imperial Highway, and in the neighborhoods east of Long Beach Boulevard to know what to expect: multiple layers of patchwork, rotted decking in the valleys, and underlayment that crumbled years ago. Our team, led by Grant Whitlock, writes every repair with a 365-Day Done Right Promise behind it. If it is not right within a year, we make it right. Free second visit if the repair fails. No fine print, no phone tree.
Styles & brands we work with






Roof Flashing Installation in Lynwood
Roof flashing installation in Lynwood is where a lot of roof replacements succeed or fail, because the older homes here have original flashing that was barely adequate in 1955 and is now rusted through at the chimneys, vents, and valleys. Flashing is the metal strips that seal the joints where the roof meets a wall, chimney, skylight, or valley. When flashing fails on a Lynwood roof, water follows the seam straight into the attic, and by the time you see the stain on the ceiling, the decking underneath has usually been wet for months. On installations in Lynwood, we almost always replace flashing completely rather than patch it, and the cost typically runs $25 to $55 per linear foot depending on the material and how much tear-out is involved.
Where flashing fails first
Valley flashing, the metal running down the inside corner where two roof planes meet, takes the most abuse on Lynwood homes. The 1940s and 1950s valley metal was thin galvanized steel, and the Mediterranean sun plus winter rain cycles has corroded it beyond saving. When we open up a valley during a Lynwood install, we routinely find the roof decking soft and the underlayment gone right where the valley runs. We install new ice and water shield in the valleys before the new flashing goes in, because that is the difference between a roof that leaks in five years and one that does not.
Chimney and pipe flashing
Every penetration in the roof, a chimney, a plumbing vent, a furnace flue, needs flashing that is still doing its job. On older Lynwood roofs we pull off and replace the flashing boots at every pipe because the rubber gaskets have hardened and cracked from UV exposure. A $12 pipe boot failing after a new roof goes on is not something we are willing to hand back to you. Our standard is to replace every penetration flashing during a new install, no exceptions, and we write that into the line-item price before we start.
TPO Roofing Installation in Lynwood
TPO roofing installation in Lynwood is the right call for the flat and very low-slope roofs on the apartment buildings and duplexes that line Long Beach Boulevard and the streets around Martin Luther King Jr. Park. TPO is a single-ply thermoplastic membrane that comes in wide sheets, heat-welded at the seams, and it reflects heat instead of absorbing it the way old built-up tar roofs do. For a typical flat roof in Lynwood, a TPO installation runs $7 to $11 per square foot including tear-off of the existing material, underlayment or cover board, and the membrane itself. Multiple layers of old roofing under the TPO always add to the price because they add to the labor.
Why TPO beats tar and gravel here
The old apartments along Long Beach Boulevard were built with low-slope roofs designed for tar and gravel or layered cap sheet, and many of them now carry three or four layers of old material. Heat-welded TPO seams do not rely on adhesive alone, which matters when summer roof temperatures in Lynwood climb over 140 degrees and thermal movement tugs at every seam. We see fewer failed seams on properly installed TPO than on any older flat roof system common in Lynwood.
When a flat roof needs full replacement
Landlords and property owners in Lynwood often ask us to patch a leak on a flat roof that is really done. The tell is puddling water that never drains plus multiple previous patches around the scuppers and roof penetrations. Once the water ponds and the patch history is long enough, a new TPO installation with proper slope or at least a new cover board to level the surface is the only fix that will not leak again in the next winter rain. We give you the written price for the full job, and you decide. No pressure, no urgency tactics.
Trusted Brands We Service in Lynwood
We install GAF, Atlas, and Tamko roofing systems in Lynwood, and we stock common components locally so we are not waiting on a distributor when your roof is open and the weather window matters. GAF architectural shingles are our most-installed shingle on Lynwood homes because they handle both the summer UV and the winter rain cycles well. Atlas and Tamko both offer strong high-wind options that we recommend for roofs with open exposure, and we can get any of these brands to a Lynwood job site fast because our supply lines are already set up to serve the city.

AfterCommon Roof Installation Problems We See in Lynwood Homes
- Multiple layers hiding rot: Many Lynwood homes have two or three layers of old composition shingles patched over the original roofing. By the time a new roof goes on, the only honest option is a full tear-off, because new shingles laid over old do not bond properly and the fasteners cannot reach solid decking. We always recommend tear-off on pre-1970 structure.
- Failed underlayment at valleys and penetrations: The original paper underlayment on 1950s Lynwood roofs disintegrates after decades of heat and moisture. We routinely find bare wood under the shingles at valleys, around chimneys, and at pipe penetrations, which is exactly where the next winter downpour finds its way in.
- Original low-slope design that holds water: Some of the older tract homes in Lynwood were built with very low slopes that drain slowly even when new. If the slope is below the manufacturer’s minimum for shingles, we will tell you and recommend a TPO or modified bitumen system instead, because installing shingles on a roof that puddles is a guarantee of future rot.
- Deferred maintenance until the ceiling caves: Landlords and owner-operators often wait until a leak has turned into a ceiling failure before authorizing a new roof. By then, the decking has been wet for months. The result is a more expensive install with a lot of structural repair that would have been avoidable a year earlier.

FAQs About Roof Installation in Lynwood
Most Lynwood homes built in the 1940s through 1960s have original roofs that are now 60 to 80 years old with multiple layers of patching on top, so a clean tear-off to the decking is the only way to inspect and properly fasten the new roof. Overlays hide decking rot and shorten the life of the new shingles. We recommend tear-off on nearly every Lynwood home we quote, and the written price includes disposal and re-decking where needed. Call (213) 521-8272 to schedule a free look at your roof.
Lynwood’s hot, dry summers with intense UV exposure break down asphalt shingles faster than in coastal areas, and the sudden winter rain events push water into any weak seam, so we recommend architectural shingles with strong UV and wind ratings, like GAF, Atlas, or Tamko, and we always install ice and water shield at valleys, eaves, and penetrations. For low-slope roofs, the reflected heat and durability of TPO beats traditional built-up roofing in this climate. Call (213) 521-8272 for a material recommendation specific to your roof’s slope and exposure.
Once we tear off an older Lynwood roof, the City of Lynwood may require that the new installation meet current building code for things like roof sheathing thickness, nailing patterns, ventilation, and flashings, especially on apartment buildings where a re-roof triggers inspection of structural connections and drainage. We pull permits, schedule inspections, and when a code requirement adds to the job, it is added to your written price before we proceed. Call (213) 521-8272 to ask about your specific property and what we can expect permit-wise.
We show you the damaged wood, explain what needs to happen, and give you a written price for the repair before we go one step further. On a single-story stucco home near Lynwood Park, our crew tore off three layers of early composition shingles to find the original 1950s tongue-and-groove decking had rotted through in two valleys from decades of deferred maintenance. We replaced the decking, installed ice and water shield in the valleys and around all penetrations, then laid GAF architectural shingles with a new ridge vent and drip edge, finishing the week before a January storm that would have caved in the living room ceiling. No change orders without your written approval, ever. Call (213) 521-8272 if you suspect your older home has rot under the shingles.
Low-slope and nearly flat roofs cannot shed water fast enough for shingles to work, especially on the aging apartment buildings along Long Beach Boulevard, where the original roof design was tar and gravel or layered cap sheet, not shingles, and the slope is too low to meet shingle manufacturer requirements. TPO is the right system for these roofs because the heat-welded seams keep water out and the membrane handles ponding better than shingles ever could. For a Long Beach Boulevard apartment roof, a full TPO install runs $7 to $11 per square foot, and the written quote includes tear-off of the old layers. Call (213) 521-8272 for a free estimate on your building.
