Fast, Reliable Roof Repair Across North Hills
Roof repair in North Hills most often comes down to two things: wind damage from Santa Ana events and the slow failure of 60-year-old materials on homes that have never had a full tear-off. We know the 91343 and 91393 housing stock well because we work on it every week. Call (866) 705-2978 when you spot a leak, missing shingles, or daylight coming through the attic.
Marquis Roof Repair serves North Hills homeowners with inspection, repair, and full replacement under one roof. We carry materials from seven manufacturers, so the right product for your roof is always available. No referrals, no generalist handyman guessing. Just a roofing specialist who investigates before recommending anything.
Why Marquis Roof Repair Is North Hills’s Preferred Roof Repair Company
North Hills homeowners call us because we understand what aging Valley tract housing actually looks like under the surface. The 1950s hip-roof stucco home on a quiet street near Sepulveda Basin is not the same roof as a newer build in Porter Ranch. Different decking, different framing quirks, different code triggers once a permit gets pulled. We have seen enough of these roofs to know what we will find before we open them up, and that matters when you are deciding between a patch and a tear-off.
Our reputation in North Hills is built on honest diagnosis. Ron Thibodeau leads the Marquis team, and his rule is simple: we investigate before we recommend. Homeowners in the 91343 corridor have told us they called other roofers and got a replacement pitch over the phone. We do not work that way. We get on the roof, inspect the decking, check the flashing, and then tell you what actually needs to happen. Sometimes that is a targeted repair. Sometimes it is not. You will know why either way.
Response time to North Hills is short because we are based just over the hill in Burbank. We are in the neighborhood regularly, which means we can get someone on your roof quickly after a windstorm or leak. That proximity also means we know exactly what the Valley heat does to asphalt, what Santa Ana gusts do to shingle edges, and what winter rain pooling does to low-slope and flat roofs around 91343.
Styles & brands we work with
Emergency Roof Repair in North Hills
Emergency Roof Repair in North Hills usually means one of two scenarios: a Santa Ana event has torn shingles or lifted flashing, or a leak has opened up during the winter rains and water is coming into a bedroom or living space. Either way, the priority is protecting the interior from further damage. We respond to emergency calls across North Hills, including the neighborhoods around Roscoe Boulevard, Woodley Avenue, and the 405 corridor. Call (866) 705-2978 and describe what is happening. We will tell you over the phone if it is safe to wait or if you need tarping tonight.
Emergency repair pricing in North Hills generally falls between $350 and $900 for temporary tarping and minor shingle or flashing work done same-visit. A wind-lifted ridge cap or missing shingle tab repair typically runs $300 to $600. Larger storm response, like re-securing an entire roof plane, can push toward $1,200 to $2,800 depending on how many squares are involved and whether decking was exposed and damaged. We give you a written line-item price before any work starts, even in emergency situations.
After a Santa Ana Wind Event
We get calls the morning after every major wind event. Homeowners walk outside and find shingle tabs scattered across the yard or sitting in the gutter. The damage is not always obvious from the ground. A lifted shingle that is still attached can let water under the roof system for months before you see a stain on the ceiling. After wind events in North Hills, we schedule rapid inspections and check for lifted tabs, broken seal strips, exposed underlayment, and loosened flashing around vents and valleys.
Tarp-Over and Interior Protection
If a storm has opened your roof and rain is forecast, we can secure a heavy-duty tarp over the affected area the day you call, in most cases. This is not a repair, it is protection. It buys you time to get a proper inspection and a written quote. We will explain exactly what the tarp covers and what it does not, and we will not leave you wondering when the real fix happens.
Flat Roof Repair in North Hills
Flat Roof Repair in North Hills is common around the 91343 corridor, where mid-century apartment buildings and commercial strips carry built-up and modified-bitumen roofs that are decades old. These roofs fail differently than pitched shingle roofs. The usual culprits are clogged drains that cause ponding, failed flashing at HVAC penetrations or parapet walls, and cracked or alligatored membrane from years of direct Valley sun. We work on these roofs often and know what aging modified-bitumen looks like right before it splits open.
Flat roof repair pricing in North Hills typically starts around $450 for a small flashing or drain repair. A targeted patched area with new membrane and sealant runs $600 to $1,400 depending on size and the condition of the surrounding material. Larger recoating or re-flashing work on an apartment building can range from $3,000 to $12,000 or more depending on square footage and how much of the existing membrane needs to be stripped. Every flat roof we inspect gets a full drainage check, because in North Hills, ponding is the number one thing that shortens a flat roof’s life.
Built-Up and Modified-Bitumen Repairs
Older built-up roofs are layered asphalt and felt, and when they leak, the water travels sideways before it shows up inside. Finding the actual breach requires experience with how water moves through those layers. We do not patch the ceiling stain and call it done. We trace the water back to the source, usually a penetration or a low spot, and repair the membrane there.
Drain and Flashing Work
On many North Hills flat roofs, the drain is the weak link. Debris from nearby eucalyptus and pine trees clogs scuppers and drains, water ponds, and the membrane fails at the seam. We clear the drainage path, re-secure loose flashing, and apply membrane-compatible sealants at every penetration. If the deck below the membrane has rotted, we cut it out and replace it before the new membrane goes on.
Trusted Brands We Service in North Hills
Marquis is authorized to install products from seven roofing manufacturers, including GAF, CertainTeed, and Owens Corning. That is unusual. Most roofers in the Valley carry one or two brands and steer every job toward whatever they stock. We do not have that conflict. We recommend the material that fits your North Hills roof, your budget, and the heat and wind loads your home actually deals with. If we are repairing a GAF architectural shingle roof, we have the matching materials. If your home has CertainTeed presidential shake or Owens Corning Duration, we can source those too. Seven manufacturer lines, one point of contact.

AfterCommon Roof Repair Problems We See in North Hills Homes
- Wind-lifted shingle tabs after Santa Ana events. North Hills sits in the Valley’s hot interior, where gusts from the foothills strip seal strips and lift shingle edges. The damage is often invisible from the street and only shows up as a leak when winter rain arrives.
- Dry, curled wood shake on 1950s-60s hip roofs. Many original wood shake roofs in North Hills have outlived their useful life twice over. Shake curls, cracks, and then hides rotten decking underneath. Nailing new shingles over it fails within a season.
- Flashing failures at valleys, vent boots, and swamp coolers. The old swamp cooler or heater flue was usually the first thing flashed incorrectly on 1950s tract homes. Over time, the flashing lifts, sealant dries out, and water follows the penetration into the attic.
- Ponding and clogged drains on flat roofs around 91343. Mid-century apartment buildings in North Hills fight standing water every winter. Water finds its way through small membrane cracks at drain seams and parapet corners, and interior damage appears slowly.

FAQs About Roof Repair in North Hills
Most original wood shake roofs in North Hills are beyond targeted repair. The shake itself is dry and curled, the underlayment is often gone, and the decking underneath is frequently cracked or rotted from decades of heat cycling. We can patch small sections temporarily, but the honest answer is usually a full tear-off and re-roof. North Hills building codes limit how many shingle layers you can have, and adding a layer over failing shake violates that limit and sets up a bad roof. We will show you photos from the inspection so you can see exactly what we see. Call (866) 705-2978 for an inspection and we will give you a straight answer.
We write allowances into every North Hills repair or re-roof contract for exactly this. When we open a roof and find rotted decking, undersized or notched framing, or old wiring that violates current code, we stop, document it with photos, explain what code requires and what we recommend, and get your written approval on the additional cost before we touch it. You will never get a surprise bill at the end. The price gets agreed to in writing first. Call (866) 705-2978 for a written estimate with allowances built in.
For pitched roofs in North Hills, we typically recommend an architectural asphalt shingle with a high wind rating, like GAF Timberline HDZ or CertainTeed Landmark, installed with six nails per shingle and proper starter strip. For flat or low-slope roofs, a modified-bitumen or TPO system with heat-welded seams holds up well to Valley UV. The exact recommendation depends on your roof’s slope, decking condition, and exposure. We are brand-agnostic, so the spec we give you is based on your house, not on what we have in the yard. Call (866) 705-2978 and we will walk you through the options.
We prioritize North Hills calls after Santa Ana events and winter storms, and we can usually get someone to your home the same day for an emergency inspection and tarp-over if needed. We are based nearby in Burbank and work in North Hills regularly, so the drive time is short. Call (866) 705-2978 as soon as you notice damage, because the first rain after a wind event is when the real interior damage happens.
Yes. We repair built-up and modified-bitumen flat roofs on the mid-century apartment buildings common around the 91343 corridor.
