About Cumberland County, ME
Cumberland County spans Greater Portland — from Cape Elizabeth and South Portland around Casco Bay through Falmouth, Yarmouth and Freeport, and inland to Windham and Gray. Dense in-town Portland housing, shingled coastal homes on Casco Bay, and a fast-growing ring of newer construction in Windham, Gorham and Scarborough.
Casco Bay salt air combines with Maine's snow totals and long shoulder seasons — the exact conditions that shorten the life of paint, sealants and asphalt shingles. That's the standard every product we install in Cumberland County has to meet — not a catalog spec, but what a Portland winter actually does to a house.
Southern Maine is a core service area, not an outpost. Cumberland County projects get full crews, in-state scheduling and the same warranty package. Woman-owned since 2011, headquartered in Beverly, MA with a branch in Bedford, NH, we've built our reputation on educating homeowners first and quoting second.
Cumberland County Roofing — Portland, South Portland, Falmouth & Every Town Between
Coastal Maine roofs face wind uplift and ice damming in the same winter, which is why full-system GAF installation beats shingle-only quotes here. We install complete GAF Master Elite® roof systems across Cumberland County — a credential held by the top 2% of roofing contractors in North America — and a new roof returns up to 68% of its cost at resale.
Built for this climate
Impact-rated, algae-resistant shingles with lifetime warranties, specified for the conditions Cumberland County actually sees rather than a national average.
Leaks fixed at the source
We diagnose the full system — flashing, underlayment, ventilation and decking — and correct the cause instead of patching the same spot every spring.
Metal roofing options
A 70-plus-year roof that sheds snow and resists ice damming — a strong fit for the most exposed homes in Portland and the surrounding towns.
Ventilated roof systems
Ice dams, attic moisture and premature shingle failure are ventilation problems. We balance intake and exhaust across the entire roofline.
GAF system warranties
A transferable lifetime shingle warranty from America's #1 roofing manufacturer, backed by our own 30-year labor workmanship guarantee.
Clean, contained job sites
Landscaping protection, daily magnet sweeps and a tidy site every evening on every Cumberland County project.

Free EstimateJames Hardie & Vinyl Siding Across Cumberland County
Casco Bay salt air is brutal on painted wood and cedar shingle, and fiber cement has become the default answer across Falmouth, Yarmouth and Cape Elizabeth. As a James Hardie Elite Preferred Contractor we install fiber cement and premium insulated vinyl throughout Cumberland County. James Hardie siding returns 144% of its cost at resale; premium vinyl returns 97%.
Colors that hold
Greater Portland trends toward Boothbay Blue, deep charcoals and crisp Arctic White with natural cedar accents. ColorPlus® Technology keeps those finishes true through years of Maine weather.
Insulated vinyl value
Rigid foam backing adds wall insulation and panel rigidity, and premium vinyl still returns about 97% of its cost at resale.
Everlast composite
Impact resistance and color retention for homeowners who want premium performance without the fiber cement price point.
Moisture defense built in
Every Cumberland County project includes HardieWrap® or premium housewrap, properly lapped and taped, because wind-driven rain finds every gap.
Trim and detail work
Corners, window surrounds, soffit and fascia finished as one system, so the whole exterior ages together instead of one detail failing early.
Transferable warranties
James Hardie's 30-year finish warranty and a transferable lifetime warranty on premium vinyl protect the investment either way.

Free EstimateReplacement Windows for Cumberland County Homes
Older Portland-area housing stock and long heating seasons make window replacement one of the highest-impact upgrades in Cumberland County. Every window we install in Cumberland County is custom-built to the opening and includes our premium energy package at no extra cost. Replacement windows deliver a 76% return on investment.
Stop paying to heat the outside
Triple-pane glass with advanced low-E coatings and insulated frames cuts heat loss at the source — Maine homeowners commonly save $500-plus per year.
Water intrusion eliminated
Foam-filled frames, precision flashing and sealed exterior trim close the paths moisture uses to get into the wall.
Harvey and premium lines
A well-regarded New England brand offered alongside other premium manufacturers, all with the same full weatherproofing and energy package.
Custom configurations
Colonial double-hungs, picture windows, casements, bays, black frames, divided lights and arched tops — sized to the openings you already have in your South Portland or Falmouth home.
Noticeably quieter rooms
Triple-pane glass measurably reduces outside noise, which homeowners on busy streets notice the first night after installation.
No upsells
The premium energy package comes standard on every window project. No add-on pricing, no surprises at signing.

Free EstimateEntry & Sliding Door Replacement in Cumberland County
Coastal Maine entries need marine-grade hardware and sealed thresholds — standard builder doors corrode and sag within a few seasons. We install ProVia entry doors and insulated sliding glass doors throughout Cumberland County — sealed, thermally broken and built to keep working through Maine winters. Entry door replacement delivers a 216% return on investment.
Sealed against the weather
Fiberglass and steel construction with thermal break cores and adjustable thresholds stop drafts and keep water out of the sill.
Storm and screen options
Self-closing storm configurations with reinforced hinges and heavy-duty hardware for exposed entries.
ProVia craftsmanship
Custom-built doors with decorative glass, hardware packages and finishes matched to your home's exterior palette.
Sliding patio doors
Insulated low-E glass, modern rollers and multi-point locking hardware that ends the cold zone in front of the door.
Curb appeal that lasts
Color-matched finishes that still look right a decade later — a meaningful difference on Portland and South Portland street frontages.
Precision installation
Level, plumb and fully weatherproofed. Most door failures are installation failures, and that's where we spend the time.

Exterior Remodeling Questions in Cumberland County
How do I find a reliable roofing contractor near me in Cumberland County?
Start with a GAF Master Elite® certified roofing contractor — only the top 2% of contractors in North America earn that designation. Look for verified credentials, a written workmanship warranty, an honest assessment rather than a scare tactic, and a roof system designed for New England's freeze-thaw cycles, heavy snow and nor'easters.
How much does roof replacement cost in Cumberland County?
Roof replacement in New England averages $35,701 for asphalt shingles and $56,282 for metal roofing, based on current Cost vs. Value data. Your actual cost depends on roof size, pitch, material choice, layers to remove and installation complexity — which is why we measure and quote in person, at no charge.
What's the difference between regular and insulated vinyl siding?
The key difference is a foam backing. Insulated vinyl siding adds a layer of rigid foam that improves energy efficiency and wall rigidity — a meaningful difference in comfort and heating costs in this climate.
What windows keep heat and cold out?
Triple-pane, ENERGY STAR certified windows are the most effective option for New England. Most drafts come from air infiltration around the frame rather than through the glass, so installation quality matters as much as the window itself.
How long do replacement windows last in Cumberland County?
Quality vinyl windows with professional installation last 25 to 30 years here, through snow load, freeze-thaw cycling and nor'easters. Fogged glass, sticking sashes or visible frame damage are the signs the current units are past their service life.
What is the exterior door installation cost?
Exterior door installation in New England ranges from $2,547 for a steel entry door to $11,953 for a grand fiberglass door, depending on material, style, glass package and installation complexity.
Do you serve Maine homeowners with the same warranties as Massachusetts?
Yes. Cumberland County projects carry identical coverage — GAF's transferable lifetime shingle warranty with a 30-year workmanship guarantee, James Hardie's 30-year finish warranty, and our own installation warranty.
How does Casco Bay salt air affect siding and roofing life?
Salt accelerates corrosion of fasteners and flashing and breaks down paint films far faster than inland conditions. We spec corrosion-resistant fasteners, sealed flashing details and ColorPlus® finishes on coastal Cumberland County homes for that reason.
