Roofing conditions in Kemmerer

What Kemmerer does to a roof

At 6,780 feet, Kemmerer gets the deepest cold and heaviest snow of any town Gregco serves. January lows near 10°F make asphalt shingles brittle, and about 47 inches of snow a year drives freeze-thaw, ice dams, and snow load that stress a roof every winter. Strong high-altitude UV ages the shingles from the top down the rest of the year.

Kemmerer, in detail

Roofing in Kemmerer, Lincoln County

Kemmerer sits at 6,780 feet in southwest Wyoming, the county seat of Lincoln County and the highest of the towns Gregco serves. At that elevation the cold is deeper and the sun is stronger, and both are hard on a roof.

Cold is the first thing that wears a roof out here. Kemmerer runs a cold continental climate. January lows average near 10°F, and the town has recorded temperatures as low as −39°F. Deep cold makes asphalt shingles brittle, and brittle shingles crack when the freeze-thaw cycle goes to work. On sunny winter afternoons the snow on a roof melts, then refreezes at night. That cycle lifts flashing, splits aging shingles, and builds ice dams along the eaves that back water up under the roof and into the ceiling. It is a leak most homeowners do not see until a stain shows up indoors.

Snow load is the second test. Kemmerer averages about 47 inches of snow a year, spread across roughly 89 days, with the heaviest months in late winter. Wet, heavy snow sits on the roof and stresses the deck, the fasteners, and any low-slope or flat sections. When we inspect after a hard winter we check the valleys, the flashing, and the first few feet above the gutter line, because that is where snow load and ice dams do their damage.

The sun is the third. At nearly 6,800 feet the ultraviolet load is high year-round, and UV dries out asphalt shingles, curls their edges, and strips the granules that protect them. A roof in Kemmerer ages from the top down even in a mild year. We look for balding, brittle shingles and for granules washing into the gutters.

Because of the snow load and the cold, material and detailing matter more here than in a valley town. Architectural asphalt shingles work, but they need strong airflow beneath the roof deck and ice-and-water shield at the eaves to fight ice dams. Standing-seam metal sheds snow fast and holds up to the cold and UV, which is why more homeowners around Kemmerer and Diamondville ask about it every year. We document what your roof actually needs, show you the photos, and let you decide. We document. You decide.

We serve Kemmerer and the surrounding Lincoln County corridor, including Diamondville, Frontier, Opal, and La Barge. If a storm just moved through, the inspection is free and there is no pressure to hire us.

What to expect

How it works

Four steps, always in the same order: on-site visit, we show you the photos, written scope, photo record.

  1. On-site visit. We look at the roof, the flashings and the drainage, and photograph what we find in Kemmerer.
  2. We show you the photos. You see the same conditions we saw, before anyone talks about scope.
  3. Written scope. What the work covers and what it does not, in writing.
  4. Photo record. We photograph the finished work and the conditions we found, for your records.
Answers, in plain words

Roofing questions from Kemmerer property owners

Straight answers about roofs, storms, and insurance claims. Still unsure? Just call.

Does the cold in Kemmerer damage asphalt shingles?

It does. Kemmerer has recorded a low of 39 degrees below zero in December 1990, per the National Weather Service, and January lows average near 10 degrees on Weather Atlas normals. Asphalt goes stiff and brittle at those temperatures, so a shingle that would flex in milder weather splits instead. The crack rarely leaks right away. It turns up as a ceiling stain months later.

How much of the winter does snow sit on a Kemmerer roof?

Most of it. Kemmerer averages about 47 inches of snow spread across roughly 89 days with measurable snowfall, per US Climate Data, so the roof carries a load far more often than it sits clear. That steady weight works on the deck and the fasteners, and the melting and refreezing builds ice along the eaves. Valleys and flashing are the first places we look.

Why doesn't the snow just melt off my roof in Kemmerer?

Because the air rarely helps. Kemmerer's January high averages 26.6°F, below freezing, per Weather Atlas climate normals. Snow that lands in January tends to stay until heat escaping through the ceiling melts it from underneath. That underside melt is what runs down and freezes at the cold eave.

When is the snow load on a Kemmerer roof at its worst?

Late winter. March is Kemmerer's snowiest month at about 6.3 inches, per Weather Atlas climate normals, and it lands on top of everything December through February left behind. A roof that carried the winter without trouble can still give way in March, when the load peaks and the melting starts.

Why is the south side of my Kemmerer roof worse than the north side?

Sun and thaw both hit it hardest. At 6,780 feet, per the US Census Bureau, ultraviolet light in Kemmerer is strong year-round, and the south slope also thaws and refreezes daily while the north slope stays frozen. That combination bakes the asphalt on one side and cycles ice on the other. Check that side first.

Have you worked in Kemmerer before?

Yes, including for the city. The documented public job in town is 27 ADA curb ramps — City of Kemmerer, WYDOT-administered, completed June 2016. That work is concrete flatwork rather than roofing, and it is offered here as evidence we have met a public agency's standards inside Kemmerer.

Do you cover Diamondville and Frontier, or only Kemmerer itself?

Both, and the towns along the corridor. Kemmerer is the seat of Lincoln County, per the US Census Bureau, and Diamondville and Frontier sit minutes from downtown. We treat Kemmerer, Diamondville, Frontier, Opal and La Barge as one service area, so a roof outside the city limits is scheduled the same way.

What time of year should a roof be replaced in Kemmerer?

Late spring through early fall. Asphalt shingles need warmth to seal to one another, and Kemmerer's January averages a high of 26.6°F and a low near 10°F, per Weather Atlas climate normals. Shingles laid in that cold sit unsealed until the weather turns. We schedule around the forecast, not the calendar.

If I put standing-seam metal on my Kemmerer house, where does the snow go?

Off the roof in one sheet, usually without warning. Kemmerer averages about 47 inches of snow a year, per US Climate Data, and that release has to be planned around doors, walkways and where people park. We check which slopes face your entries before recommending standing-seam here.

Why do the gutters on my Kemmerer house fill with solid ice?

Because the meltwater refreezes before it can drain. Snow falls on roughly 89 days a year in Kemmerer, per US Climate Data, so a gutter refills about as fast as it clears. The gutter is the symptom. The eave detail behind it, including Ice & Water Shield, is where the fix belongs.

Does a low-slope roof in downtown Kemmerer need a different system?

If your building in the Triangle has a low slope, yes. A low slope holds snow instead of shedding it, and Kemmerer averages about 47 inches a year across roughly 89 snowfall days, per US Climate Data. Single-ply membranes such as TPO and EPDM are built to sit under that load.

Do metal flashing and sealants survive Kemmerer's worst cold?

They move under it. Kemmerer's record low is 39 below, set in December 1990, per the National Weather Service. Metal contracts hard at that temperature while the deck under it barely shifts. Winter after winter that works fasteners loose and splits old sealant at chimneys and sidewalls. We check those joints first on an older Kemmerer roof.
