Roof Inspections & Maintenance in Kalispell

Sisu Roofing performs roof inspections in Kalispell and across the Flathead Valley, and the drone is what makes ours different. Instead of a roofer's verbal impression from a ladder, you get a documented aerial survey of every slope, valley, and flashing line, with the photos in your hands. We inspect for homeowners who want a straight answer, buyers and sellers who need one in writing, and owners working through an insurance claim.

What the inspection covers

A Sisu inspection starts with a full drone flight: every slope photographed, ridges and valleys examined at a detail level that ladder inspections miss, and problem areas captured close-up without anyone walking a wet or icy roof. Where the aerial view flags something, we follow up on the roof itself and in the attic, because half the story of a Flathead roof is written on the underside: moisture staining, daylight at penetrations, compressed insulation, and the ventilation problems that feed ice dams. You get a written summary with the photos, not a sales pitch with a clipboard.

When to inspect a Flathead roof

Two moments a year matter most here. Spring, after the snow releases, is when winter's damage shows: ice dam scarring at the eaves, popped fasteners from freeze-thaw, and valleys scoured by sliding snow. Fall, before the first real storm cycle, is the last cheap chance to fix small problems while they are still small, because a minor flashing gap in October is an interior leak by February and it will not be fixable until the thaw. Beyond the seasonal rhythm, inspect after any significant hail or wind event, and before buying or selling a home.

Maintenance that prevents the big repair

Most expensive roof failures start as cheap ones. A lifted shingle becomes a wet deck. A cracked pipe boot becomes a stained ceiling and a mold call. Clogged valleys and gutters become ice dams that peel back the eaves. Our maintenance visits work that list: resealing exposed fasteners, replacing tired boots, clearing valleys and gutter lines, and re-securing flashing before wind finishes the job. For metal roofs, fastener checks are the whole game. It is unglamorous work, and it is the highest-return money most owners ever spend on a roof.

Inspections for real estate and insurance

A roof is one of the biggest numbers in any Flathead home sale, and vague answers help nobody. For buyers, our documented inspection turns 'roof looks okay' into photos and a condition summary you can negotiate from. For sellers, a pre-listing inspection removes the surprise that kills deals in week three. And when hail or wind moves through, our aerial documentation gives your insurance adjuster dated, comprehensive evidence, which our roof insurance claims page covers in detail. In every case the deliverable is the same: what is actually true about the roof, in writing.

What homeowners say about Sisu roof inspections

Kalispell and Flathead Valley homeowners, in their own words.

Ben and his team provided excellent communication and service. They were in and out and a couple of days tearing off and replacing a steep roof. We will use them again for future roofing needs on our homes.

Roof Inspections: questions we actually get

How often should I have my roof inspected in Montana?

Twice a year is ideal here: spring, to find what winter did, and fall, to fix small problems before snow makes them unreachable. At minimum, inspect after any hail or major wind event and before buying or selling. Regular inspections cost little compared to the deck rot they catch early.

What does a drone roof inspection show?

Everything a walking inspection shows, plus the areas too steep, icy, or fragile to walk. The aerial photos capture shingle condition, flashing lines, valley wear, and storm damage across every slope, and they create a dated record you can hand to a buyer, an insurer, or your own file.

How much does a roof inspection cost?

It depends on the size and complexity of the roof and whether you need a written report for a sale or a claim. It sits at the inexpensive end of anything a roofer does, and it routinely pays for itself by catching one small problem before it becomes a structural one.

Do I need a roof inspection before buying a house?

It is one of the smartest checks in the purchase. General home inspectors often assess roofs from the ground or eaves. A roofer's inspection with aerial documentation tells you the roof's actual condition and remaining life, which can be worth a significant price negotiation on Flathead homes.

What roof maintenance actually matters?

In this climate: keeping valleys and gutters clear so ice dams have less to work with, replacing pipe boots before they crack through, re-securing and resealing flashing, and checking fastener lines on metal roofs. Small, boring tasks, done before winter, prevent most of the expensive calls we get in spring.
