This project spotlight walks through a recent Milcon roof replacement in McLean, VA, a stately brick colonial where the original 27-year-old shingle roof had reached the end of its service life. The homeowner needed a premium-grade replacement that would match the architectural character of the neighbourhood and carry a warranty transferable at any future sale. What follows is the full project story: initial estimate, product selection, installation, and completion.
Every detail here is drawn from an actual McLean installation. If you are planning a roof replacement for your McLean home and want to see how a certified premium install actually looks in practice, timeline, decisions, results, this case study is the closest thing to walking through the project with Matt Kavanah personally.
The Project at a Glance
- Location: McLean, VA (Fairfax County)
- Home type: Two-story brick colonial, approximately 3,800 square feet
- Roof area: 32 squares (approximately 3,200 square feet of roof surface)
- Existing roof: Original 3-tab asphalt shingles, 27 years old, significant granule loss and cupping
- New roof product: GAF Timberline HDZ architectural shingles in Charcoal
- Additional work: Ridge ventilation upgrade, drip edge replacement, ice and water shield throughout
- Warranty issued: GAF Golden Pledge lifetime warranty (transferable)
- Total installation time: 2 days on site
Why This Homeowner Called Milcon
The homeowner had noticed the tell-tale signs of an aging roof for 18 months, dark streaking on the north slope visible from the street, occasional shingle debris in the yard after wind events, and a rising insurance renewal that specifically called out the roof age as a contributing factor. Three roofing companies had already provided estimates. What brought the homeowner to Milcon was the referral from a McLean neighbour whose own installation Matt had completed two years earlier.
The neighbour’s specific comment: “Milcon was the only contractor who didn’t try to sell me something I didn’t need.” That word-of-mouth signal is what most McLean roofing decisions are driven by, the McLean market values quiet quality and referral trust over pressure sales. Milcon’s business model was designed for exactly this environment.
The Estimate Visit
Owner Matt Kavanah conducted the estimate visit personally. The visit took approximately 90 minutes and included several components most contractors skip entirely.
Full roof measurement and condition assessment
Matt used both drone imaging and on-roof physical inspection to measure the total roof area accurately and identify all penetration points, valleys, ridges, and complex flashing details. The measurement came in at 32 squares, meaningfully different from one of the competing estimates which had quoted 28 squares and would have underestimated the material requirement.
Attic ventilation inspection
Matt accessed the attic to evaluate the existing ridge ventilation and soffit intake. The original 1998 installation had undersized ridge venting, a common issue on McLean colonials from that era. The proposed installation included ridge vent replacement to current code standards, which was flagged in the estimate before signing rather than presented as a surprise upgrade mid-project.
Decking condition discussion
The estimate specified how any decking damage discovered during tear-off would be priced: $95 per sheet of OSB or plywood, with immediate notification if damage exceeded 3 sheets before proceeding. This transparency around a common surprise cost is a Milcon standard, homeowners are never surprised by a decking-related invoice at project completion.
Written itemised quote within 24 hours
Matt delivered the written itemised quote 22 hours after the estimate visit. The quote specified exact shingle product and colour, ice and water shield placement (eaves, valleys, and penetrations), drip edge and starter shingle products, ridge ventilation upgrade scope, warranty registration process, and the exact decking damage pricing framework. Every line item was pre-priced with no ambiguity.
What differentiated the estimate: The three competing estimates ranged from $10,800 to $19,500, a spread that immediately signalled quote quality inconsistency. Milcon’s itemised quote at $16,200 came in mid-range but was the only estimate that fully specified the scope, ridge ventilation upgrade, and decking framework. The homeowner later commented that the itemised format made comparison possible for the first time.
Product Selection: Why GAF Timberline HDZ in Charcoal
The product selection conversation covered three primary options: standard architectural shingles, GAF designer shingles, and standing seam metal roofing. For this McLean colonial, GAF Timberline HDZ in Charcoal was the recommendation for several specific reasons.
- Architectural fit: The dimensional profile reads as premium without being ornate, appropriate for the colonial architecture without over-detailing
- Storm rating: 130 mph LayerLock wind warranty specifically addresses Fairfax County storm exposure
- Algae resistance: 25-year StainGuard Plus critical on the north-facing slope where mature oak canopy creates persistent shade
- Colour: Charcoal complements the brick facade colour palette, a natural choice on McLean colonials
- Warranty availability: Timberline HDZ installed by a GAF-certified contractor qualifies for the Golden Pledge lifetime warranty, the strongest coverage available in residential roofing
Installation, Day by Day
DAY 1 Tear-Off, Deck Inspection, and Underlayment
7:15 AM, Milcon crew arrived at the McLean property. Matt was on site personally for the tear-off phase. Dumpster placed strategically on the driveway with tarps deployed to protect the landscaping, foundation shrubs, and air conditioning units. Ladders positioned. Materials staged at the driveway edge for efficient handoff to the roof.
7:45 AM to 11:30 AM, Full tear-off of the original 3-tab shingles across all 32 squares. Two crew members maintained continuous cleanup below to catch any material overshooting the tarps. Homeowner remained inside, noise was present but manageable, no interior disruption.
11:30 AM to 12:30 PM, Deck inspection revealed 2 sheets of OSB requiring replacement (below the 3-sheet notification threshold). Damage was located at the north valley where prior ice damming had caused sheathing rot. Both sheets were replaced with new OSB matching the original thickness.
12:30 PM to 4:00 PM, Ice and water shield installation at all eaves, valleys, and penetrations (6 feet up from eaves on this McLean project, exceeding code minimum). Drip edge installed at all eaves and rakes. Full synthetic underlayment rolled out across the entire deck.
Day 1 ended with the roof fully protected under underlayment. Matt walked the property with the homeowner and confirmed the day’s progress before crew departure.
DAY 2 Shingle Installation, Ridge Ventilation, Final Details
7:00 AM, Crew arrived and immediately began starter shingle application at all eaves and rakes. GAF Pro-Start starter shingles were specified for optimal wind resistance.
7:30 AM to 3:00 PM, Full field installation of GAF Timberline HDZ shingles in Charcoal. The 32-square area with two dormers, three valleys, and a chimney flashing detail required approximately 7.5 hours of field installation. Fastening pattern followed GAF’s LayerLock specifications for 130 mph wind warranty qualification.
3:00 PM to 4:30 PM, Ridge cap installation and ridge vent upgrade to code-compliant profile. The undersized 1998 original ridge vent was replaced with a properly sized product providing the required intake-exhaust balance. Chimney flashing detailing completed with new step flashing and counter flashing.
4:30 PM to 5:30 PM, Full cleanup and magnetic nail sweep across the yard, driveway, and adjacent walkways. Tarps removed from landscaping. Dumpster prepared for next-day pickup. Exterior pressure wash of any dust film on windows and siding.
5:30 PM, Final walkthrough with the homeowner. Matt walked through the completed installation, showed photos of the decking replacement, and provided the warranty documentation packet including the GAF Golden Pledge registration confirmation.
The Completed Result
The completed installation delivered on every specification from the original quote, without a single scope change, additional invoice, or homeowner surprise. The roof carries a GAF Golden Pledge lifetime warranty covering both materials and installation labour, transferable to any subsequent owner at sale. The homeowner’s insurance carrier subsequently reduced the annual premium by acknowledging the new roof age and warranty coverage.
Two-day timeline. Full itemised quote respected. Zero out-of-scope invoicing. Complete cleanup. Warranty documentation delivered at closeout. This is what a properly executed McLean, VA roof replacement looks like when the contractor is set up to deliver rather than to sell.
What the Homeowner Said
Homeowner feedback (paraphrased with permission): “Matt was the only contractor who walked me through exactly what would happen and then did exactly that. The itemised quote made it clear what I was getting. The crew was on time, cleaned up thoroughly, and left the property looking better than when they arrived. I’ve already recommended Milcon to two neighbours.”
