Siding in Longmont, CO

Fiber-cement and engineered siding installed to manufacturer spec to stand up to Longmont's hail, downslope wind, UV fade, and freeze-thaw.

Family-owned · Licensed & insured · 4.9★ from 150+ Front Range reviews · Owens Corning Platinum Preferred

Out at the mouth of the St. Vrain Valley, Longmont sits lower and more exposed than Boulder just to the west, which drops it right into Colorado's hail alley. Storms rolling off the foothills in spring and summer pelt siding with hail, drive rain behind seams on downslope wind, and the high-plains UV bleaches south- and west-facing walls year-round. On older frame homes around Old Town and Fox Hill, that shows up as splitting, chalking, and rot behind worn-out original cladding; on the newer builds in Clover Basin, Southmoor Park, and Renaissance, it shows up as faded, brittle builder-grade panels that crack on the first real impact.

Built for Longmont's hail and wind

Out on the open plains below the St. Vrain Valley, Longmont siding takes direct hail impact and rain forced behind seams by downslope wind off the foothills. We spec impact-resistant fiber-cement and engineered panels and fasten them to manufacturer detail so walls shed the next storm instead of cracking.

UV- and freeze-thaw-rated finishes

High-plains sun fades south- and west-facing Longmont walls fast, and the town's wide freeze-thaw swings work loose anything installed cheap. We use factory-finished, color-stable siding rated for Colorado UV and temperature cycling, so the look lasts and the warranty stays intact.

Right material for every Longmont home

From century-old frame and brick near Old Town and Prospect New Town to builder-grade panels in Clover Basin and Renaissance, we match the siding to the house, not a one-size template, and install it to keep water and weather out for the long haul.

Common questions

What does new siding cost on a Longmont home?
It depends on the home's size and stories, how much old cladding and rotted sheathing has to come off, and whether you choose engineered/vinyl or premium fiber-cement. Two-story homes, the tricky details on older Old Town and Fox Hill houses, and added energy-efficiency upgrades all factor in. We give a free, itemized in-home estimate so you see the real number before any work starts.
Will insurance help pay for hail-damaged siding?
Often, yes. Longmont sits in Colorado's hail alley, and a storm that cracks, chips, or punctures siding can be a covered claim. We inspect honestly, document the damage properly for your adjuster, and never pressure you to file or sign on the spot. If it's not a real claim, we'll tell you that too.
How long does a siding replacement take in Longmont?
Most single-family homes run a few days to about a week, depending on size, the siding system, and how much repair the underlying sheathing needs once the old cladding is off. Longmont weather and any city permit can shift the schedule, and we'll walk you through the timeline and pull required permits before we begin.
