Modified Bitumen Roofing around Ogden
Torch and self-adhered modified sheets for low-slope.
Modified Bitumen Roofing for Ogden homes and buildings
Mod-bit in plies with the cap sheet detailed at every edge and penetration.
A lot of Ogden’s housing stock is brick and craftsman with steeper pitches and real character, and roofs there reward being detailed properly rather than covered quickly. Valleys and chimney flashing are where these houses leak.
A proven low-slope system where a membrane is not the right answer.
What matters on modified bitumen roofing
Drainage before material
The first question on any low-slope roof is where the water goes. Ponding is what kills membranes, and a roof that holds water for days after a storm will fail early regardless of which sheet is on it. We look at the slope, the drains and the terminations before we talk about material.
Seams and terminations
Field failures on commercial roofs are rare. Failures at seams, curbs, drains and the parapet edge are common. A hot-air welded seam that has been probed is a continuous sheet. Anything taped or glued and unverified is a scheduled leak.
How the system goes together
A welded seam versus a glued one
On a single-ply roof, the seams are the whole roof. Heat welding fuses the two sheets into one piece of plastic, and a properly welded seam is stronger than the sheet either side of it. An adhesive seam relies on a bond that ages at a different rate than the membrane does.
How a seam gets proven
A probe run along the edge of every weld while the crew is still on the roof. If the probe catches, the seam gets rewelded then and there, not written down for later.
Cold days need slower welds
The machine settings change with the air temperature or the weld runs cold and looks fine.
How long a bead of sealant lasts
Roof sealant is a consumable. In this climate, with the ultraviolet load and the temperature swing, a good product stays flexible for a handful of years and then shrinks, crazes and pulls away from one side of the joint. That is normal and expected behavior for the material.
Design so sealant is a backup
Every joint that matters should shed water by its shape, with the sealant there as a second line. Where sealant is the only thing standing between water and the deck, somebody has signed you up for a maintenance visit every few years.
Ask what is holding a repair together
If the answer is caulk, ask again.
What we check
- Field condition and granule loss
- Valleys, ridges and every transition
- Penetrations and their flashing
- Gutter and fascia condition
What the job looks like
Get on the roof
We walk it rather than look from the drive, check the decking underfoot, the flashings and the ventilation, and photograph what we find before any number is discussed.
Show you what we saw
The photographs come back to you with a plain read of what the roof needs and, just as often, what it does not need yet.
Crew on site
The crews we hire work under Hancock’s direction, staged so landscaping and the drive are protected, working the detail in the order it is supposed to go on rather than the order that is quickest.
Leave it clean
Site cleared at the end of every day, a magnet run over the whole yard for nails at the finish, and the roof walked with you before we go.
Southwest exposure ages fastest
If you only had time to look at one slope on a house here, look at the one facing between south and west. It takes the high sun through the middle of the day and it takes the afternoon heat, so the binder in the asphalt gives up there first. Cupped tabs, bare patches of mat, and a granule line in the gutter under that slope alone.
A roof can be two ages
And knowing that keeps a repair from turning into a replacement it did not need to be.
The wet spring snow problem
Late season storms carry more water per inch than anything that falls midwinter. That heavy stuff clings to a roof instead of sliding, pushes on gutters, and refreezes at night into a solid mass on the overhang. It is also the load most likely to find a framing weakness.
After a heavy spring storm
Walk the drip line and look for bent gutter hangers and separated seams. Then look at the ceilings inside along exterior walls.
What we check on the deck
Spongy sheathing between rafters, especially over the eave where the ice sat.
Where roofs go wrong
The shortcut we see most
A membrane laid over wet insulation because tearing off would have cost a day. The roof looks finished, the moisture stays underneath, and the sheet fails early from below.
What good looks like instead
Moisture surveyed, wet sections cut out and replaced, drainage corrected, then the membrane installed and its seams probed.
Signs worth a look
- Ponding water still standing two days after rain
- Seams that have lifted or opened at an edge
- Blisters or ridging across the field
- Interior staining near drains, curbs or the parapet
What to expect
Scheduling around your operation
Most commercial work can be staged so the disruptive part happens when the building is quiet. Tear-off noise, crane or hoist time and material deliveries all get planned against your hours rather than ours.
What the roof survey covers
Before specifying anything we survey the existing assembly: slope and drainage, moisture in the insulation, the condition of seams and terminations, and how the roof is being used. A roof somebody walks on weekly needs a different answer from one nobody touches.
Documentation
Commercial and public work runs on records. We photograph the existing condition, the work in progress and the finished assembly, so there is a file rather than a recollection.
Getting to Ogden
Working Ogden regularly rather than occasionally is what makes an honest read possible. We have been on enough roofs across Weber County to know which subdivisions came from the same builder and inherited the same shortcut.
That proximity is most of what matters when weather moves through. Ogden sits in Weber County, and we are on roofs across it regularly enough to know how the housing there was built.
Questions we get asked
Not the question you had? Call the shop and ask a person. We would rather talk it through than have you guess from a website.
(801) 382-8898Do you actually work in Ogden?
Regularly. Ogden is ordinary working territory for us, not an outlying job we take when it is quiet.
How fast can you get to Ogden after a storm?
We make the roof safe first, then come back and do the repair properly when conditions allow.
Do you work through the winter?
Yes, with judgment. Shingles need to seal, and in genuine cold that takes longer or needs hand sealing. Emergency work happens whenever it has to. Full replacements get scheduled around the weather rather than forced into it.
What makes a Utah roof different?
Snow load, ice at the eaves, canyon wind and high-altitude sun, all on the same roof. A crew that learned roofing somewhere mild has to learn it again up here.
How do I know when a roof is getting close?
Granules collecting in the gutters, tabs lifting or curling at the edges, shingles that look bare in patches, and daylight or staining in the attic. Any of those is worth a look.
Where Ogden sits on our map
Ogden is inside the sixty mile radius we cover around Salt Lake City.
