WHY MARYLAND HOMEOWNERS CHOOSE APPER
Apper Construction has been a family-owned, Maryland-licensed contractor since 2016. We focus on one thing: protecting and improving homes across Anne Arundel and Howard County with roofing, siding, windows, gutters, and doors that last.
Every job is installed by our own W-2 crews — never subcontracted — and built to a spec that holds up: architectural shingles, full ice-and-water shield, and ridge venting that meets current Anne Arundel County code.
You get a written, line-itemed estimate before anything is scheduled, clear pricing with no high-pressure sales, and a job site left clean — guaranteed. Licensed under MHIC #05-146983 and carrying $2M general liability.

Energy-efficient replacement windows with lifetime glass-breakage coverage — they pay you back on every energy bill.
James Hardie fiber-cement and premium vinyl siding — color-matched, weather-tough, and built to lift your home's curb appeal.
Seamless aluminum gutters and leaf-guard systems sized to your roof — moving Maryland's heavy downpours away from your foundation.
