Flat Roof Repair
Flat Roof Repair in Lakewood, CO That Stops Leaks
A flat-roof leak rarely shows up where the water gets in. It travels under the membrane, along the deck, and appears on a ceiling far from the failed seam or flashing. The fix is finding the real entry point — a split seam, a clogged drain, a lifted parapet cap — and repairing that, not the spot on the ceiling. Call (720) 817-3348 and we will trace the leak before touching the membrane.
Service overview
What Flat Roof Repair in Lakewood Actually Involves
A flat repair starts with the water, not the ceiling stain. We walk the roof after rain if we can, find where water ponds, check the seams and the flashing at every penetration and parapet, and test the drains. The repair itself is usually one of three things: a seam is cleaned and re-welded or re-adhered, flashing at a parapet or penetration is rebuilt, or a drain is cleared and resealed. The membrane around the repair is checked too, because a patch over a failing membrane is a patch you will pay for twice.
Not every flat roof is a repair candidate. If seams are splitting across the whole roof, if the membrane is brittle, or if ponding is caused by a deck with no slope at all, a repair buys a season and the leak comes back. In that case we say so and point you to a full flat roof installation with tapered insulation instead. Lakewood requires a permit for a repair of 100 square feet or more, pulled before work starts through eTRAKiT. This business serves residential clients, including multifamily homes.

Practical benefits
Why a Targeted Flat Repair Beats Another Patch
Flat repairs fail when the diagnosis is wrong. Here is what a proper one looks like.
The Entry Point Gets Found
We trace the water from the roof side and the ceiling side before cutting anything. On a low-slope roof, the stain and the leak are rarely in the same place.
Seams Repaired Properly
A failed seam is cleaned and re-welded or re-adhered, not covered with sealant. Sealant over a split seam is the most common failed flat repair we see.
Drains Cleared and Tested
A clogged drain turns a sound membrane into a pond. We clear it, reseal it, and test it before we leave.
An Honest Repair-or-Replace Call
If the membrane is done or the deck has no slope, we say so. A repair on a roof that needs a rebuild wastes your money.
How service works
What to Expect During Your Flat Repair
Most flat repairs are done in a visit or two. Here is the sequence.
STEP 01
Roof Inspection
We walk the roof, check the seams, flashing, and drains, and photograph the ponding and the failed detail so you can see what we found.
Tools and methods
Tools and Methods We Use on Every Flat Repair
Heat welder for TPO
A split TPO seam is re-welded into a continuous sheet rather than glued over, so the repair is as strong as the membrane around it.
Adhesive and seam tape for EPDM
An EPDM seam is re-bonded with adhesive and seam tape, flexible enough to hold through temperature swings.
Membrane patch
A patch cut to size and welded or adhered over a puncture, with the edges sealed.
Roofing nail gun
Base layers and flashing are fastened at the spacing the membrane maker specifies, so the repair holds under wind and snow load.
Chalk line
A chalk line marks the repair area and the drain locations, so the work stays true to the slope.
Safety harness and ladder stabilizer
On parapet edges and two-story buildings the crew works tied off with a harness and ladder stabilizer.
Flashing at parapets and penetrations
Flashing at parapets and penetrations is rebuilt for a low-slope system, not adapted from a shingle detail.
Drain snake and flush
Clears a clogged drain and tests the flow before we leave.
Ice-and-water shield patches
Self-adhering membrane goes under the repair area where water concentrates. Lakewood does not require an ice barrier; this is best practice on a flat repair.
Magnetic sweep cleanup
Fasteners, screws, and membrane offcuts are picked up from the yard and driveway before we leave.
Where this service fits
When a Flat Repair Is the Right Call
One seam has split but the rest of the membrane is sound
A single failed seam is a repair. We clean it and re-weld or re-adhere it, and check the seams around it for the same failure.
A drain is clogged and the roof is ponding
A cleared and resealed drain often fixes the ponding without touching the membrane. We test the flow before we leave.
Flashing lifted at a parapet or a vent pipe
Parapet caps and vent flashing are the most common flat-roof leak points. Rebuilding the flashing stops the leak at its source.
A puncture from a falling branch or foot traffic
A membrane patch welded or adhered over the puncture is a straightforward repair, as long as the membrane around it is still sound.

How Flat Roof Repair Works in Lakewood
Flat and low-slope roofs in Lakewood are mostly on homes with additions and on multifamily buildings, and a repair on one is a diagnosis first. Ponding is the failure mode that matters most: water standing on a membrane works every seam, and the roof also carries a 30 psf snow load, so a deck that has sagged under it will pond worse every year. The question on a repair is whether the problem is a clogged drain, a split seam, or a deck with no slope — the first two are repairs, the third is not.
Flat-roof leaks show up differently by building and by area, and ponding is the usual suspect. The seven areas we work in are on our locations page.
Problems we solve
Roof Problems a Flat Repair Solves
These are the problems where a repair is usually the right answer — and where we will tell you if it is not.
A leak that appears only in heavy rain
Wind-driven rain finds the one failed seam or flashing joint. We trace it, repair the seam or rebuild the flashing, and test the area.
Water ponding in one low spot
If the ponding is from a clogged drain, clearing it fixes the problem. If the deck itself has no slope, a repair will not hold and the roof needs tapered insulation.
A seam splitting near a penetration
Seams fail first where the membrane meets a vent or a parapet. We clean and re-weld or re-adhere the seam and rebuild the flashing around it.
A ceiling stain far from any visible damage
Water on a low-slope roof travels under the membrane before it shows inside, so the stain is rarely above the leak. We trace it from both sides instead of patching the stain.

Why Our Crews Get Flat Repairs Right
A flat repair is only as good as its diagnosis, and on a low-slope roof the diagnosis is the hard part. There is no state roofing licence in Colorado. Lakewood registers its roofing contractors with the City as Class 5h, Roofing and Waterproofing, and the 2021 International Residential Code is the standard we build to. What we find is photographed, the scope is written before work starts, and if a repair will not hold we say so and explain why.

Notes from local customers
What Lakewood Homeowners Say
Keith and his crew are top notch, they replaced our roof quickly and the work looks great. Keith is honest and great to deal with. Highly recommend!
Great company to work with. would definitely recommend
Keith recently re-roofed our house and did a really great job. The price was fair and I would recommend him to anyone. He personally supervised the work and kept the site very clean.
Denver-metro market data from Angi puts most roof repairs at about $287 to $980. Those are market ranges, not this business's prices. A seam repair or a cleared drain lands near the low end; a parapet flashing rebuild costs more. We give you a written scope before work starts so you know what the repair covers.
Because the entry point was never found. On a low-slope roof, water travels under the membrane before it shows inside, so the stain is rarely above the leak. We trace the water from the roof side and the ceiling side before repairing anything.
If the ponding is from a clogged drain, yes — clearing and resealing the drain fixes it. If the deck itself has no slope toward a drain, no repair will hold, and the roof needs tapered insulation as part of a full installation.
A permit is required for a repair of 100 square feet or more, pulled through the City's eTRAKiT system before work starts. Smaller repairs do not need one. We check the scope and handle the permit when it applies.
