Fast, Reliable Roof Replacement Across Van Nuys
Roof replacement in Van Nuys runs $8,500 to $24,000 for most homes, depending on whether you’re tearing off a flat built-up roof or re-shingling a low-slope ranch. We work throughout the 91401, 91405, and 91411 zip codes, and we quote every job off an actual site inspection, not a satellite image. Most Van Nuys homes are 1950s and 60s tract builds with low-slope or flat roofs that have been re-covered two or three times already, so the real cost drivers are tear-off, decking repair, and haul-off, not shingle choice.

Why Huntington Beach Roofers Is Van Nuys’s Preferred Roof Replacement Company
We have walked hundreds of Van Nuys roofs, and we know what the Valley sun does to them. The heat off the asphalt on a summer afternoon here is different from what a coastal roof gets, and it shows in the sealants, the flashing, the membrane. We scope every Van Nuys job for what actually fails in this climate: cracked hot-mop, dried-out modified bitumen, soft decking hidden under old re-covers.
Homeowners call us after the first real rain of winter when the leaks finally surface. By then the damage is usually already done. We inspect first and recommend second, which means we will tell you when a repair will buy you a few more years and when you are throwing money at a roof that is already past life.
Neil Stratton leads our crews on the Valley work. He has been up on enough Van Nuys fourplexes to know exactly what a 1960s built-up roof looks like underneath the gravel, and he quotes it honestly.
Styles & brands we work with
Reroofing in Van Nuys
Reroofing in Van Nuys usually means re-covering an existing low-slope or flat roof with a fresh membrane or shingle layer instead of tearing everything off. It is the right move when the decking is still sound and there is only one existing layer. On a typical Van Nuys ranch or fourplex, reroofing runs $6,500 to $12,000, and the work is faster because there is no tear-off labor or haul-off cost.
What Reroofing Does Not Fix
If the decking under the old layers has gone soft from years of trapped moisture, a re-cover hides the problem instead of solving it. We probe the deck during inspection and will not recommend a re-cover over compromised sheathing.
When a Re-Cover Makes Sense Here
Some Van Nuys roofs were built with 1×6 solid sheathing that is still in workable shape, and those decks can take a fresh cap sheet or shingle layer without issue. If the inspection confirms the structure is sound, a re-cover gets you a watertight roof at roughly two-thirds the cost of a full tear-off.
Flat Roof Replacement in Van Nuys
Flat roof replacement in Van Nuys is the most common job we do here, because the postwar housing stock was built with low-slope and flat built-up tar-and-gravel roofs as standard. A full tear-off and replacement with modified bitumen or a TPO-style membrane typically runs $10,000 to $18,000 on a small fourplex or ranch. That price includes hauling off the old gravel and tar layers, replacing soft decking, and installing new flashing at every penetration.
Tear-Off vs. Re-Cover on a Flat Roof
When a flat roof has multiple existing layers, building code limits how many more you can add. At that point a tear-off is the only legal path, and it reveals what is actually underneath. We frequently find soft sheathing at the valleys and around old vents, and that gets replaced before any new membrane goes down.
Membrane Choices for Valley Heat
Modified bitumen holds up better than older asphalt cap sheets under repeated 100°F-plus days, and it is what we recommend for most Van Nuys flat roofs. If you are comparing bids, ask what membrane is being quoted and whether the flashing is being replaced or just re-sealed.
Trusted Brands We Service in Van Nuys
Seven brands. One contractor. We are authorized to install GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral, which means the product recommendation follows your roof and your budget, not our inventory. For Van Nuys flat and low-slope work, we commonly quote GAF modified bitumen systems, Atlas peel-and-stick membranes, and Tamko cap sheets, and we stock local parts and fasteners in our trucks so we are not waiting on a supply house when your roof is open. Match the material to the roof, not the other way around.
Common Roof Replacement Problems We See in Van Nuys Homes
- Multi-layer re-covers hiding soft decking. Decades of hot-mop layers trap moisture against the original 1950s sheathing, and by the time we tear off, the deck needs replacement before any new membrane goes down.
- First-rain leak flushing after a long dry spell. After a summer of 100°F-plus days, the first real winter storm in Van Nuys pushes water past dried-out flashing and cracked sealant, and apartment owners call us all at once.
- Failed hot-mop built-up on flat fourplex roofs. The original tar-and-gravel systems on those small stucco apartment buildings are decades past life, and the gravel does not protect the membrane anymore, it just hides the cracks.
- Minimal attic ventilation cooking the underside of the deck. Valley heat builds up in unvented attics and bakes shingles and membranes from below, which shortens the life of even a brand-new roof if the ventilation is not corrected during replacement.

FAQs About Roof Replacement in Van Nuys
Van Nuys was built out in the 1940s through 1960s as postwar tract housing, and the developers used low-slope and flat built-up tar-and-gravel roofs because they were cheap to install at scale and the Valley climate does not get snow load. The distinctive roofing story here is flat and low-slope roofs on densely packed postwar tracts and apartment rows, not the steep-pitch shingle work that dominates most of the country.
The dry season from April through October is the most predictable window, because you are not racing winter rain. That said, the heat itself is hard on crews and materials, so we schedule membrane work in the early morning hours during summer. Call (833) 467-4901 and we will walk you through the timing for your specific roof.
Line up the tear-off scope, the decking allowance, the membrane or shingle brand, and the flashing work side by side. A bid that is $3,000 lower usually means someone is not tearing off all the existing layers or is skipping decking replacement. We give you a written line-item quote so the comparison is apples to apples, not guesswork.
Yes, if the membrane is specified for the Valley’s UV and heat load. Modified bitumen and TPO-style membranes hold up far better than old asphalt cap sheets under repeated 100°F-plus days. The bigger variable is attic ventilation. If the deck is not vented, the heat bakes the underside of the roof and shortens its life regardless of what is on top.
Yes. We replace roofs on detached garages, shops, and ADUs throughout Van Nuys, and we scope them separately from the main house because the roof systems and deck conditions are usually different. If you are adding an ADU or converting a garage, we can tie the new roof into the existing drainage and flashing correctly from the start.

How Van Nuys’s Building Stock Shapes Every Roof Replacement We Scope Here
Van Nuys is ground zero for mid-century San Fernando Valley tract housing. Thousands of low-pitch 1950s and 60s ranch homes and small stucco fourplexes were built with original tar-and-gravel and hot-mop built-up roofs, and those systems are now decades past life and cracking under Valley sun. The homes sit on tight lots with mature trees overhanging the roofs, which means more debris on the deck and more flashing failures at the eaves. Most of what we replace in Van Nuys is not steep-pitch shingle work. It is membrane tear-offs and re-covers on low-slope decks with minimal attic ventilation, and the scope decisions that matter are labor, haul-off, and deck repair, not shingle color.
On a 1950s ranch off Victory Boulevard near Van Nuys, our crew tore off three layers of hot-mop built-up over the original roof deck, found soft sheathing at the valleys, and replaced it before laying a GAF modified bitumen cap sheet with new flashing at every penetration. We reset the drip edge and fascia along the low-slope eave, added soffit venting to move Valley attic heat, and the homeowner finally stopped chasing the first-rain leaks every winter.
That job is not unusual here. It is the standard Van Nuys roof replacement, and it drives the quote far more than any shingle brand ever could.
