EPDM roofing in McLean, VA: who keeps it inspected, and what a repair is

Tenure and year built, with margins

Source: Census Bureau, American Community Survey 2024 five-year estimates (2020 to 2024), McLean CDP, table B25036. Original ten year bands were combined here; margins for the combined bands were computed by the root-sum-of-squares method the Census describes. Margins are at the 90 percent level.

Which person holds the roof, by building type

Owner-occupied house

The owner decides, after reading the county permit list and any recorded association guidelines.

Rented house

The landlord holds the roof. A tenant who sees a stain should photograph it and report it in writing under the lease, since the Census table says nothing about lease terms.

Townhouse in an association

The recorded declaration says whether the roof is an owner item or a common component. Virginia law requires the board to study reserves for capital components at least every five years and review the study each year.

Condominium or co-op building

The board and manager commission inspections. Ask whether the roof is a common component, who keeps the inspection record, and when it was last updated.

Commercial or mixed-use building

The owner or property manager decides, and the county permit list for commercial work applies. The 100 square foot line on that list is covered below.

For the street-level picture, the McLean roofing guide sets out the county permit list, the historic overlay and the association layer. This page stays with the membrane itself.

What an EPDM inspection looks at

No single public document is a complete inspection standard for a McLean rubber roof. Three neutral sources agree on the order of a walk-through: an industry trade article reposted by the EPDM Roofing Association, a second trade article on maintenance planning, and a federal guide specification for EPDM roofing.

1. Drainage first. The trade article quotes an SPRI member advising that the fall visit start with a check of drains, scuppers, gutters and overflows for debris. The federal specification, written for new roofs, goes further and tests each drain: run a hose into it for five minutes, clear a slow drain, and repeat until it flows freely.
2. Ponding. The same article describes a discoloration ring as an obvious sign of repeated ponding. Water standing away from the drains is the question to put to the inspector.
3. Soft spots. Walking the roof can reveal soft areas. The ARMA technical director is quoted advising that each location be noted and compared with the interior for signs of water entry.
4. Perimeter and flashings. The checklist names loose coping or fascia, missing splice plates, opened seams, empty fastener holes and loose gutter straps. A second article singles out flashings at penetrations, parapets, curbs and equipment bases as places that need deliberate examination.
5. Sealant and surface. Exposed sealant at termination bars and flashings should be checked for UV deterioration. If the reinforcement fibers show through the membrane, the ARMA director says the roof is "likely approaching the end of its useful life cycle," and a recover or replacement is the likelier path than a repair.
6. Moisture below. The federal specification, again for new work, calls for infrared moisture testing under ASTM C1153 across the whole roof area to confirm that insulation is dry. A surface walk cannot show that.

Patching cured rubber

The specification governs a new installation, not a patch on an aged roof, so it is a reference point, not a repair standard. Neither source gives a procedure for a particular patch size. The ARMA director quoted in the trade article advises conferring with the manufacturer and preparing the surface as its instructions require.

• Which area is being patched, in square feet, and where it sits on a sketch.
• Whether the repair material is cured or uncured, and why that choice fits the location.
• What cleaning and surface preparation the manufacturer calls for before the patch.
• Whether the repair sits on dry insulation, and how that was confirmed.

When a repair is a repair

The Virginia existing-building code gives each level of work its own definition. The text below was read on a third-party copy of the 2021 code, so confirm the wording with the county.

1. Routine maintenanceCleaning drains and checking sealant. The repairs chapter says routine maintenance and the abatement of wear from normal service are outside its repair requirements.
2. RepairDefined as reconstruction, replacement or renewal of any part of an existing building to maintain it or correct damage. The chapter lists patching and restoration of damaged materials. Undamaged parts that must be touched for the repair count as part of the repair.
3. Roof coatingThe definitions cover a fluid-applied adhered coating used for roof maintenance, roof repair or as part of a covering system. ERA describes coatings as one way to restore an aged membrane, so ask which of those a proposal means.
4. RecoverA new covering installed over the existing one without removing it. The code sets its own conditions for when this is allowed, and the county can say how it applies.
5. ReplacementRemoval of the existing covering, repair of any damaged substrate and a new covering.

Permits follow the wording too. The state building code lists replacement of 100 square feet or less of roof covering, in any building group, among the ordinary repairs that need no permit, and it exempts unlimited replacement in house-type groups where the nominal wind speed is not over 100 miles per hour. Fairfax County lists roof repairs among the work that does need a permit, under both residential and commercial headings, while its no-permit lists mention shingle replacement and, for commercial work, under 100 square feet of covering. A trade article also notes that some codes bring the entire roof into compliance once a repair passes a share of the roof area, such as 25 percent. Ask the county whether that applies in McLean.

Records worth asking for

The federal specification asks the installer to leave a roof information card listing the system. The list is a good model for a McLean owner or association to request from whoever last worked on the roof.

• Deck type, membrane, number of plies and how the membrane is attached.
• Insulation, cover board, tapered insulation for drainage, and whether a vapor retarder is present.
• Date of completion, installer contact and manufacturer contact.
• Time-stamped photographs from each inspection, filed with the building record, as the trade article advises.
• A signed report from each inspection, including any repair, with materials named.

Book a phone consultation to talk through a McLean EPDM roof. For the membrane itself, the general EPDM roofing page and the materials overview carry the basics. The flat roof, roof repair, roof replacement, commercial roofing and services pages cover scope, and the McLean guide covers the local paperwork.
