EPDM Roofing in Cypress built for flat roofs
EPDM Roofing in Cypress is a single-ply rubber membrane system made for flat and low-slope roofs that take sun, heat, and standing water all year. We install, repair, and recoat it for homeowners, HOAs, and commercial property managers across Cypress and Orange County. If your flat roof is leaking, ponding, or past 20 years old, we can inspect it this week and give you a straight answer.
Service overview
What EPDM Roofing in Cypress actually involves
EPDM Roofing in Cypress is a flat-roof system built from large sheets of ethylene propylene diene monomer, a synthetic rubber membrane that resists UV, ozone, and temperature swings better than most older flat-roof materials. We roll out 45-mil or 60-mil sheets, seam them with splice adhesive and seam tape, and mechanically fasten or fully adhere the membrane over a clean substrate. Edges get metal drip edge and termination bars, penetrations get pipe boots and flashing, and the whole assembly is pressure-checked before we leave. Cypress has a lot of 1960s through 1980s tract homes, apartment buildings, and small commercial buildings with flat or low-slope roofs. Those roofs see summer surface temps above 140 degrees, winter rain that finds every seam, and ponding water that sits for days after a storm. If you have been searching for EPDM roofing in Cypress CA near me and want a roofer who actually works on flat roofs every week, that is what we do. We also handle affordable EPDM roofing Cypress CA work for landlords who need a long-term fix, not another patch.
! Problems we solve
Ponding water sitting on the roof for days
Standing water works its way into seams and flashing, and it is the number one cause of flat-roof leaks in Cypress. Left alone, it also adds weight and shortens the membrane's life.
Lifted or separated EPDM seams
A lifted seam lets water straight into the insulation and ceiling below. It usually shows up as a stain on the ceiling or a musty smell in the room, and it gets worse with every storm.
Flashing failure at walls and penetrations
Most flat-roof leaks start where the roof meets a wall, pipe, or skylight. Failed flashing lets water behind the membrane, which leads to roof rot and expensive deck repairs if it is ignored.
Scope of work
What our EPDM roofing service includes
Every EPDM project is different, but most Cypress installations include the same core scope. Here is what is covered in a standard quote, and what we price separately if your roof needs it.
-
01
Tear-off and disposal
We remove the existing roofing material, haul it to the landfill, and dispose of it properly. That includes old gravel, modified bitumen, or a previous membrane. We protect your landscaping and driveway during the process and clean up with a magnet sweep for nails.
-
02
Deck inspection and repair
Once the old roof is off, we inspect the sheathing for rot and soft spots. Damaged plywood gets replaced before the new membrane goes down. We show you photos of anything we find and get your approval before we do the repair work.
-
03
Insulation and cover board
We install polyiso insulation and a cover board to give the EPDM membrane a smooth, stable surface. This also improves the roof's R-value, which helps with cooling costs in Cypress summers. Thickness depends on your building and code requirements.
-
04
Membrane, flashing, and drainage
The core of the job is the EPDM membrane itself, plus all the details that keep it watertight: drip edge, termination bars, pipe boots, seam tape, and flashing at walls and curbs. We also confirm drains and scuppers flow before we finish.
Why Cypress property owners choose EPDM
EPDM is not the cheapest flat-roof option, but it is one of the longest-lasting. Here is what our Cypress customers get when they choose a rubber membrane over another patch or a short-lived coating.
Request a quoteTools and methods we use on EPDM roofs
Roofing nail gun
We use a roofing nail gun to fasten the cover board and insulation to the deck before the membrane goes down. It is faster and more consistent than hand-nailing, which matters on larger Cypress commercial roofs.
Seam roller
A seam roller presses the splice adhesive and seam tape into the membrane so the seam bonds fully. We roll every seam by hand, because a seam that is not rolled is a seam that will lift.
Moisture meter
We use a moisture meter to check the deck and insulation for trapped water before we install new membrane. If we find wet material, it has to come out, or the new roof will fail from the inside.
Caulking gun and utility knife
We use a caulking gun to seal termination bars and flashing details, and a utility knife to trim membrane and cut around penetrations. These are the small tools that determine whether the details stay watertight.
Local execution
Cypress sits in Orange County with a warm, dry summer and a short but intense rainy season from December through March. Flat roofs here bake at surface temperatures above 140 degrees in July and August, then get hit with rain that finds every seam. The housing stock is mostly 1960s to 1980s tract homes, apartment buildings, and small commercial properties, and a lot of them have flat roofs over garages, additions, and entire structures. That means we see a lot of ponding water, failed flashing at parapet walls, and old modified bitumen that has reached the end of its life. If you need a Cypress CA EPDM roofer free estimate, we inspect the roof, check the deck, and quote the job with local code requirements in mind. California requires cool-roof materials on many re-roof permits, and white or light-gray EPDM meets that standard. We also pull permits when the job requires it and schedule inspections with the city so your project stays compliant.

When your flat roof leaks, we answer
Flat-roof leaks do not wait for business hours, and neither do we. Our Cypress crews are on call 24/7 for emergency EPDM roof repair, and we typically have a technician at your address within 60 to 90 minutes for urgent calls in the 90630 area. Our trucks carry 45-mil and 60-mil EPDM membrane, splice adhesive, seam tape, pipe boots, and tarping materials, so we can stop the water on the first visit in most cases. If the leak needs a permanent repair, we schedule it as soon as the weather allows. We keep a crew of four to six roofers available for storm response, and we prioritize active leaks, occupied buildings, and properties with tenants. Call us any time and you will talk to a real person who can get a crew moving.
How our EPDM installation process works
Free roof inspection
We walk the roof, check the deck, look for ponding water, soft spots, and failed flashing, and take moisture readings. You get photos and a written scope the same day. Most Cypress inspections take 45 to 60 minutes, and there is no charge.
Written estimate
You get a line-item quote that shows membrane thickness, insulation, flashing, and labor separately. We explain what is required by code and what is optional. Most Cypress homeowners get their estimate within 24 hours of the inspection.
Tear-off and deck prep
We remove the old roofing, haul it off, and inspect the deck. Rotted sheathing gets replaced, and we install a cover board or recovery board so the new membrane has a smooth surface. A typical 1,500 square foot roof takes two to three days.
What EPDM roofing costs in Cypress
EPDM roof installation in Cypress runs $5.50 to $9.50 per square foot in 2026, depending on the size of the roof, the condition of the deck, and how much insulation and flashing the job needs. A typical 1,500 square foot flat roof falls between $8,250 and $14,250. Repairs and recoats cost much less, usually $450 to $2,200. We give you a line-item estimate so you can see exactly where the money goes, and we do not add charges without your approval.
Roof size and access
Larger roofs cost more overall but less per square foot, because setup and mobilization are spread across more area. Difficult access, like a roof surrounded by landscaping or a steep ladder pull, adds labor time and can raise the price.
Deck condition
If the sheathing is rotted or soft, it has to be replaced before the new membrane goes down. We inspect the deck after tear-off and show you what we find. Most Cypress roofs need some deck repair, but the amount varies widely.
Membrane thickness and insulation
60-mil membrane costs more than 45-mil but lasts longer, and we usually recommend it for Cypress roofs that see heavy sun. Adding polyiso insulation and a cover board raises the price but improves energy performance and extends membrane life.
