Siding Installation & Replacement in the Flathead Valley
If you need a siding contractor in Kalispell, MT, we can help. Sisu Roofing & Construction installs LP SmartSide engineered wood and metal siding across the Flathead Valley, from our shop in Kila. Most people know us for roofs. Siding is a natural extension of that work, because the roof and the walls share one job: keeping water out.
Why a roofing crew is a good siding crew
Almost every siding failure we see starts where the roof meets the wall. Kickout flashing that was never installed, step flashing buried behind the cladding, gutters dumping onto a lower wall. A siding crew that has never worked a roof tends to treat those spots as someone else's problem. We flash them the way we would on a roof job. When we handle siding installation in the Flathead Valley, water management is the starting point, not an afterthought.
Siding that holds up in the Flathead Valley
Walls here take real abuse. Freeze-thaw cycles work moisture into every gap. Summer hail comes in off the mountains. South and west walls take hard sun at elevation, which dries out cheap cladding fast. And on homes with metal roofs, snow sheds off in slabs and hits the lower walls on the way down. We recommend two materials for these conditions, both built for impact and cold, and both backed by manufacturer warranty programs.
- LP SmartSide: treated engineered wood, paintable, tested for hail impact
- Metal siding: board-and-batten and panel profiles that shrug off snow shed
One contractor for the whole exterior
If your roof and siding are both near the end of their life, doing them together is usually the smart sequence. One mobilization instead of two. The roof-to-wall flashing gets built as one system instead of two crews pointing at each other. And you deal with one licensed Montana contractor (license 400855IC) instead of coordinating trades yourself. Ben Wuollet runs every project from our Kila shop, and we serve 17 towns across the valley.
What drives the cost of new siding
We price every siding job from the walkthrough, not from a per-square guess over the phone. These are the factors that move the number:
- Material choice: LP SmartSide and metal carry different material and labor costs
- Wall area and stories, since staging and ladder work add labor
- Condition of the sheathing under the old cladding
- Trim scope: corners, window and door wraps, soffit and fascia
- Water management details like kickout flashing and gutter corrections
- Access, including steep sites and landscaping we need to protect
When we'd tell you to repaint instead of reside
- Your wood siding is sound and the only problem is failed paint. Prep and repaint costs a fraction of new siding and buys years.
- One wall is weathered but the boards are tight, flat, and dry. Paint the wall, save the reside for when it is actually needed.
- The damage traces back to a gutter or roof problem. Fix the water source first, or new siding will fail the same way.
- Your roof is the more urgent failure. Water comes from above, and a failing roof will ruin new siding from behind.
