Our Roofing Services in Kent, WA
Roof Replacement
Two houses a mile apart in this city can need different specifications, because one sits on the valley floor and one sits on the hill above it. We price a replacement only after we know which one you have.
Roof Leak Repair
A leak that returns to the same spot every winter is telling you something about the building, not only about the roofing. Around here the answer usually depends on which side of the hill you live on.
Storm Damage Restoration
Storm work in this valley means wind, water and falling trees. It does not mean hail, and it does not mean tornadoes, so an estimate here that reads like one written in Texas should make you suspicious.
Hail Damage Roofing
This page exists mostly to talk Kent homeowners out of a hail claim. Damaging hail is uncommon in the Puget lowland, and nearly everything we are called out to look at here turns out to be something else.
Wind Damage Roofing
Wind takes a roof apart from the edges inward. That is why the part of a Kent specification we argue about most is the perimeter: starter course, drip edge, rake fastening and the way the ridge caps are nailed down.
Roof Inspections
An inspection here is worth paying for when it produces numbers you can compare against later. On ground that is still consolidating, the useful question is never only what the roof looks like today.
Asphalt Shingle Roofs
Laminated asphalt shingle is the right answer for most houses in this city, on the hill and on the valley floor alike, and it is worth being clear about why rather than treating it as the default nobody had to justify. The reasons are physical.
Metal Roofing
Standing seam metal is a genuinely good roof and it is the wrong purchase for a particular kind of Kent house. Knowing which kind you have before you spend the money is the whole point of this page.
Tile Roofing
Our rule on tile in Kent is short. If your house was built with tile, we will keep it working for decades.
Flat & Low-Slope Roofing
A low-slope roof is a drainage plan pretending to be a roof. On buildings sitting on the Kent valley floor, that plan has a habit of quietly going out of date, and most of the ponding we are called to look at started as a slope that used to work.
Roof Coatings & Sealing
Coatings are the product most often sold into the wrong situation on this whole list. Applied to a sound membrane with positive drainage, it buys real years.
Roof Ventilation
More than half the attic moisture complaints we look at in this valley are not roof leaks. They are humidity, and a good part of it is arriving from underneath the house rather than through the covering over it.
Skylights
Two things about skylights are specific to this city. In a long gray winter they earn their keep more than almost any other improvement, and in that same winter a good half of the leaks reported around them are not leaks at all.
Gutters & Downspouts
Gutter work in western Washington is not about capacity in a downpour. Our rain arrives as long, moderate frontal events, and the systems that fail here fail because they are blocked with conifer needles and organic debris, or because of where they put the water once they have collected it.
Fascia & Soffit
Fascia is where a wet climate takes its time. Nothing dramatic happens to it.
Chimney Flashing
Of everything standing on a roof, a masonry chimney is the hardest to keep dry, and in this region it is also the element most likely to be damaged by an earthquake. Both point at one question: is yours still doing a job worth paying for.
Emergency Tarping
A tarp is a thirty-day answer, and anybody who tells you otherwise is selling you a permanent solution that will fail in the first hard southerly. What it buys is time to make a proper decision without water running through your ceiling while you make it.
Commercial Roofing
The flat ground between the hills is warehouse, distribution and light industrial floor area, and the roofs over it are large, low slope and sitting on the same filled valley bottom as the houses. That last part changes how a competent survey is done.
Insurance Claim Help
We help with claims by being useful and clear about the limits. Roofing is our trade and claims advocacy is not: bargaining with a carrier for you takes a public adjuster license in this state.
Kent Roof Pros is a registered, bonded and insured roofing contractor in Kent, Washington, covering roof replacement, leak repair, storm and wind damage, flat and low-slope roofing, metal roofing, tile repair, ventilation, skylights, gutters and commercial work. We install Class A laminated asphalt shingles, standing seam metal, mechanically attached single-ply membrane and two-ply modified bitumen.
Every quote we write starts with one local question that most estimates skip. Kent is built on two entirely different grounds: a valley floor of river alluvium and engineered fill, and hillsides of dense glacial deposit east and west of it. A roof plane that has gone out of line on the floor means something different from the same measurement taken up on East Hill, and the specification follows that answer.
So we string the ridge, read the deck, check intake ventilation and write down numbers before we talk about products. You get an itemized scope with unit prices for deck repair, dated photographs, the permit pulled in our own name, and a written workmanship warranty. Where a repair is the correct spend we quote the repair, and we put the reasoning in writing.
What Kent Customers Say
Third roofer we had out and the first to run a string along the ridge instead of just looking at the shingles. Turned out the dip was the house, not the roof, and they said so before quoting anything. We got the framing looked at first and then they did the reroof. Honest people.
We were quoted a coating on the warehouse roof by two companies. These guys cut cores first, found soaked insulation over half the building and told us a coating would have trapped it. Cost more to do it properly and we would have paid twice otherwise.
A door knocker told us we had hail damage. Kent Roof Pros chalked a square, counted, photographed it and said there was nothing there worth filing on, then showed us the blistering that was actually causing the granule loss. They charged us for the inspection and saved us a claim.
Ceiling stains every January and no leak in the rain. They checked the crawl space before they checked the roof, found the vapor barrier half missing, and fixed the intake vents in the attic. Two winters clear now. Nobody else even asked about under the house.
Why Kent Chooses Kent Roof Pros
- ✓We establish which ground your address sits on, valley fill or glacial hillside, before a specification is written, because the two need different roofs
- ✓Ridge and eave offsets are measured and recorded on the first visit and again at completion, so the file shows whether anything is still moving
- ✓We decline coating work where the ponding traces back to building settlement, and we put the reason in writing rather than taking the job quietly
- ✓Nobody here will write a hail claim on a Puget lowland roof. We chalk a test square, count the hits and give you the number even when it kills the job
- ✓Roof water is tightlined to an approved discharge point rather than soaked into compressible ground beside a shallow foundation
- ✓Washington registers contractors without examining them, so we hand over the registration number and invite you to check the bond and claim history yourself
About Kent Roof Pros in Kent, WA
Kent Roof Pros works Kent, Auburn, Renton, Tukwila, Federal Way, Covington and the surrounding King and Pierce county communities, on houses and on the low-slope buildings that fill the valley floor. We are registered with Washington Labor and Industries, carry liability cover and workers compensation, and pull our permits in our own name through the City of Kent.
The reason we ask about ground before products is that this valley was a floodplain until living memory. The White River was pushed south to Commencement Bay by the flood of 1906, and the Howard A. Hanson Dam, dedicated in 1962, ended the seasonal flooding that had kept the valley in farms. What went up afterwards sits on alluvium and fill, and buildings on that material settle unevenly over decades. Roofs show it first.
There are jobs we turn down. If your deck plane has moved far enough that a structural opinion should come first, we will not sell you a covering to hide it. If your low-slope roof ponds because the building settled, we will not coat it and pretend the warranty covers standing water. And if you want a hail claim written on a Puget lowland roof, we are not the firm for that.
How It Works
- 1
Assessment, and which ground you are on
We start on foot wherever the pitch allows it, put an extension-pole camera over anything too steep or too brittle to stand on, and take a moisture meter into the attic if there is a hatch. We also string the ridge and eave lines and record the offsets, because on this valley floor those numbers are the difference between a roofing problem and a building problem.
- 2
A written scope with unit prices
The estimate lists the assembly by layer, names the actual products with their data sheets, and carries agreed unit rates for sheathing, rafter tails, fascia and furring before anybody starts. Nothing gets repriced from the roof halfway through a Tuesday.
- 3
Permit, schedule and weather
Roof work in Kent takes a permit, and we pull it in our own name through the Permit Center. Then we size each day's tear-off to the forecast, because a roof opened wider than the crew can dry in before the next front is how ceilings get ruined.
- 4
Cleanup, documentation and the follow-up measurement
Magnetic sweep of the site, debris hauled the same day, and a photo set covering the bare deck, every flashing detail and the finished roof. On houses where we recorded ridge offsets, we take the same measurements again at completion so the file has a baseline for whoever looks next.
Commercial and Warehouse Roofing on the Kent Valley Floor
The flat ground either side of the Green River carries distribution centers, manufacturing and flex space, and those roofs sit on the same filled valley bottom as the housing around them. Buildings on that material settle unevenly, so drains, scuppers and crickets drift away from the elevations the original roof plan assumed. We survey before we price, on a numbered grid after rainfall, with core cuts logging the existing assembly and the moisture in it.
- ✓As-is roof surveys on a numbered grid, with ponding depth and drain elevations recorded after rainfall
- ✓Core cuts through the assembly to log existing layers and check insulation for trapped moisture
- ✓Tapered polyisocyanurate layouts designed off the measured deck rather than the original drawings
- ✓Mechanically attached and fully adhered single-ply membrane, with tightened fastening in perimeter and corner zones
- ✓Two-ply modified bitumen where roof traffic around equipment is heavy
- ✓Rooftop unit curbs, gas line supports and pitch pockets raised and reflashed rather than roofed around
- ✓Occupied-building sequencing that closes and dries in each opened area before the crew leaves
- ✓Roof asset files with photographs, warranty documents and a maintenance schedule handed over at completion

Frequently Asked Questions
Does a re-roof in Kent, WA need a building permit?
Yes. The City of Kent requires a building permit for adding, repairing or removing a roof, and it is applied for through the Permit Center. We take it out in our own name, which means the inspection record attaches to us rather than to you, and you can look the permit up against your address afterwards.
How do I know whether my house is on the valley floor or the hill?
Elevation is the quick test and the city's own mapping is the real one. Kent City Code designates much of the valley bottom as a seismic hazard area, drawn from the state liquefaction studies for the Auburn, Poverty Bay, Des Moines and Renton quadrangles. If your address falls inside it, your house sits on alluvium and fill rather than on glacial ground, and we quote accordingly.
Does it hail enough in Kent to damage a roof?
Rarely. Western Washington gets long frontal rain and wind rather than the deep convective storms that make bruising hail, so most of what gets called hail damage here is blistering, mechanical damage or weathering. We chalk a test square and count the hits before anyone talks about a claim, and we will tell you when the answer is no.
Can you re-roof during the wet season?
Yes, with the day sized to the forecast. We open only as much roof as the crew can tear off, dry in and make watertight before the next band of rain, which sometimes means a four-day job takes six. The alternative, opening a whole roof under an optimistic sky in November, is how interiors get damaged.
There is moss on my roof. Does that mean I need a new one?
Not by itself. Growth on a shaded slope is a maintenance item, and the questions that matter are whether the granule surface is still intact, whether courses have been lifted, and whether anyone has already scraped it with a shovel. We will tell you if the roof still has years in it, because it usually does.
My ceiling stains in cold weather but not when it rains. What is that?
Almost always condensation rather than a leak, and in this valley a good share of the moisture comes up from the crawl space through damp ground. We check the vapor barrier below and the intake ventilation above before selling roof work, and quite often the fix is under the house rather than on top of it.
