Proudly Serving Salt Lake, Davis, Weber, & Utah Counties

This is home. Our base is in Lehi, so Utah County roofs are the ones we look at most, and the pattern here is a temperature swing rather than one single hazard. NOAA's engineering weather data puts Provo Airport at 74 freeze-thaw cycles in an average year, and summer does the other half of the work.

The exceptions are worth knowing. Traverse Mountain and the bench above Alpine take wind coming over the Point of the Mountain and down American Fork Canyon. Provo's northeast side catches the air pouring out of Provo Canyon. Down near the lake the wind eases off and heat takes over instead.

Davis County gets its own warning because the wind here is not ordinary weather. When the pressure difference builds east of the mountains, air comes down Farmington, Parrish, Mueller Park and Holbrook canyons hard enough to strip shingles off roofs, and it happens often enough that local homeowners plan for it.

What decides whether a roof comes through a Davis County wind event is whether its shingles can still move and reseal. A flexible shingle lies back down. A brittle one tears at the tab and lets go, and once one goes the wind gets underneath the next. That is the exact property that age takes away and that restoration puts back.

Park City is the hardest roof environment we work in, and it is the one place where two extremes hit the same roof. UV climbs with elevation, and the EPA puts the increase at about six percent per kilometer, so a Park City roof takes measurably more of it than a valley roof on the same afternoon.

That is the summer half. The winter half is heavier: deep snow sitting for months, then thawing and refreezing at the eaves. A shingle that has kept its flexibility handles that. A dried out one does not.
