Roofing & Exterior Contractor for Kalamazoo and Southwest Michigan.

Reasonable Roofing & Contracting is a Michigan roofing and exterior contractor, family-run since 1984, licensed statewide and working across Kalamazoo County and the communities around it — Portage, Texas Township, Oshtemo, Richland and Gull Lake, Mattawan and Paw Paw.

We are an Owens Corning Platinum Preferred Contractor and a GAF Master Elite™ roofer. Those are two separate manufacturer programmes, held together by roughly the top 3% of roofing contractors in the country, and they are the reason we can register a system warranty in your name rather than hand you a piece of paper with our own logo on it. Our inspectors are HAAG-certified, which is the credential insurance adjusters are trained to recognise when a storm claim is in dispute.

On this side of the state we are launching on roofing and seamless gutters — residential, commercial and insurance work, those two trades done properly rather than six done thinly. Siding and the rest follow as the west-side team grows. It is a deliberate choice and we would rather state it than take work we are not yet set up to do well.

This is not a quiet corner of the state. Four events in three years have put roofs across Kalamazoo, Calhoun, Van Buren and Allegan counties into claim:

• 10 August 2026 — 2.50-inch hail over Kalamazoo. Claims from this storm are still being settled.
• 5–7 March 2026 — an EF3 tornado at Union City with 160 mph winds.
• 15–16 May 2025 — 80 mph straight-line winds and roughly 244,000 customers without power.
• 7 May 2024 — an EF2 through the county: around 50 homes destroyed, more than 500 structures damaged, and a county state of emergency.

Two-and-a-half-inch hail does not always leave a hole. It bruises the mat under the granules, and the roof fails two or three winters later — long after the claim window your policy allows. That is why the inspection matters more than the repair.

Kalamazoo County sits in the lake-effect snow belt downwind of Lake Michigan, which means a roof here holds snow longer and through more freeze-thaw cycles than a roof on the east side of the state. That is what builds an ice dam.

The mechanism is always the same: heat escaping into the attic melts the snow in the middle of the roof, the meltwater runs down to the cold overhang, and it refreezes at the eave. The ridge of ice that forms there holds the next melt back until it finds its way under the shingle and into the ceiling below. The water stain on your bedroom ceiling in February is almost never a hole in the roof — it is an attic that is too warm.

Which is why the repair is rarely more shingle. It is intake ventilation at the soffit and exhaust at the ridge in a balanced pair, air-sealing the leaks that let warm house air into the attic in the first place, insulation brought up to depth without burying the intake vents, and a proper ice barrier membrane at the eaves — which Michigan's residential code requires to run from the eave edge to a point at least 24 inches inside the warm wall line. Anyone who quotes you an ice-dam fix without going into the attic is guessing.

• Balanced intake and exhaust ventilation — not just more vents
• Attic air-sealing at the top plates, can lights and bath fans
• Insulation to depth, with the soffit intake kept clear by baffles
• Ice barrier membrane at every eave, valley and low-slope transition
• Heated cable only where the geometry genuinely leaves no other option
