What's included

Flat roof repair in Skiatook, OK

Patch it, or take the whole flat section off? That's what a leaking porch asks, and the answer sits at the transition, where the low slope runs under the shingle above it. You'll hear which one you're facing.

Low-slope additions sit all over Skiatook, on porches, sunrooms and carports. The Osage County storm record lists 23 hail days in the last four years, and hail doesn't bruise a flat section the way it marks shingles. It punctures, and you won't see it until the ceiling stains.

Warranty on a flat repair splits two ways. The membrane or coating is the manufacturer's; the workmanship on the joint is our roofer's, both named on the estimate you keep.

The transition flashing

The joint where the low slope tucks under the pitched roof gets opened, checked and re-flashed with metal. Sealant smeared over that junction lasts a season, then it's open again.

Seams and laps

Every joint between sheets is probed along its whole length, top to bottom. A seam that's let go in one place has usually been working loose either side of it.

Penetrations and curbs

Pipes, vents and any rooftop unit get their boots and collars pulled back and sealed again. They're holes somebody cut on purpose, and they age faster than the sheet around them.

Low spots and drainage

Where water stands, the fall of the roof and the way it drains both come into the repair. A low spot that's patched but still ponds will come back.

The wet-insulation check

Before anything is coated or patched, the layers under the leak are checked for trapped moisture. Sealing over wet insulation hides water it doesn't remove, and the deck underneath keeps paying.

Photographs and the itemized list

Our roofers photograph the failure under the covering, and those pictures sit beside the itemized list you're given. Every line on it shows up in a photo too.

What ponding water is telling you

Water that's still sitting up there two days after the rain is the sign worth acting on, because a low spot adds weight, works at the seams around it, and turns a small weakness into the leak you finally notice inside. The rest of what a flat section tells you isn't out in the open field, it's at the edges and the penetrations.

A puddle that is still there Tuesday

Rain on Saturday and standing water on Tuesday means it's got nowhere to go. Every day it sits it adds weight and works at whatever seam it's lying against.

A damp patch that is nowhere near the roof fault

Water on a low slope runs sideways under the covering until it finds an opening, so the wet corner inside can sit several feet from the failure. That's why chasing the ceiling stain straight up patches the wrong spot.

A soft spot underfoot

Decking that gives a little when somebody walks it means moisture's been sitting in the layers below. Coating over a soft area shuts that water in where it'll keep working on the deck.

A seam edge you can lift with a fingernail

Where two sheets are joined is where a flat roof usually opens first. A lifted seam is a small repair while it's still a seam, and a much bigger one once wind gets underneath.

Cracked sealant around a pipe or vent

Every pipe, vent and curb is a hole in the roof that something has to seal. That sealant ages faster than the sheet around it, so it's near the top of the list on any leak call.

Drips that start where the addition meets the house

A low-slope roof bolted onto a pitched one has to be flashed up underneath the shingle course above it. Cut short or nailed through, it'll leak in the first hard rain and keep leaking after.

Identify the system before pricing a fix

Nobody can price a repair on a covering they haven't identified, so that's where our roofers start.

Identify

What is up there

A single-ply membrane, a rolled asphalt system and an older built-up roof each fail in their own way, so the first job is working out which one you've got.

Trace

Find the entry

Water on a low slope travels, so the search runs from the stain inside back up to whatever seam, flashing or penetration it's coming through.

Open

Check what is wet

Where the leak is found the layers come open far enough to show whether the insulation below has taken on water, and that's what decides whether you're looking at a repair or a tear-off.

Price

Repair or section

What comes back is a written scope that separates the patch from a full section replacement, with a figure set against each so you can see what you're choosing between.

What it costs

Two causes, two different prices

Two things put water through a low slope, and they price differently because they are different work. Ponding is a drainage problem, so the low spot has to be built back up until water leaves on its own, and how much of the field comes up to do that is what decides the bill. A failed transition where the addition meets the house is flashing work instead, priced off the length of the run and how much of the wall has to be opened to flash it properly. Which one you have is settled up on the roof, never from the stain on the ceiling.

Nobody can price this one off a table. You get a figure once our roofer has walked the low slope and found which of the two you're dealing with.

Low-slope questions in Skiatook

What Skiatook homeowners ask once a low-slope section starts leaking.

Most flat-roof leaks are repairable, because low-slope roofs fail at their joints and their low spots long before the field of the covering wears out. Replacement becomes the answer when the insulation underneath has gone wet across a wide area or the deck's started to give, since a patch laid over saturated layers seals the water in and the roof keeps failing beneath it.
A low-slope addition has to be flashed up underneath the shingle course above it, and that transition is the most common failure point on a bolted-on porch or sunroom. Water coming down the pitched roof arrives at the junction with speed behind it, so a flashing leg cut short or a fastener driven through the wrong place won't hold past the first hard rain.
Ponding water breaks a covering down from the top while adding weight the deck was never asked to carry, and it magnifies whatever small weakness it's sitting on. Standing water two days after the rain is the point where a low spot stops being cosmetic and starts being why you've got a leak.
Repairs to a seam, a flashing or a penetration are usually finished in a single visit once the right material's on hand, while replacing a whole low-slope section runs longer, and the work waits on dry weather either way. Order of operations matters more than speed here, because a patch bonded to a damp surface won't last.
Commercial low-slope roofs run on the same physics at a different scale, with drains, tapered insulation and rooftop equipment that a residential porch roof doesn't have. Buildings whose drainage is a design question of its own are covered on the commercial roofing page; a flat section over an addition is a house repair and belongs here.
