Shingle Color Fades in St. Louis Sun, So Name the Shade in the Spec

The shade on a shingle sample board is not the shade you will see in year six. Asphalt shingles get their color from the granules pressed into the top surface, and those granules are exposed to St. Louis summer sun, hail season debris, pollen, and the freeze thaw cycle every winter. Light colors show dirt and streaking sooner, dark colors absorb more heat and show wear more plainly, and both change with age in ways a sample board cannot show. Before you pick a shade, you need to know what the spec names, how the crew will get that exact shade onto your roof, and what happens if it is not available on the day the bundles arrive.

Material and spec

A shingle order has two names that people mix up. The product line is the family of shingles, such as a dimensional laminated shingle, and the color name is the specific shade within that line as the manufacturer prints it on the wrapper. Quotes often shorten the color name to something like charcoal or weathered wood. That short name is fine for a conversation, but it is not enough for a spec. Ask for the full color name exactly as the manufacturer lists it, and write it into the contract beside the product line. Keys installs Atlas and Malarkey shingles only, so the color you choose will come from one of those two catalogs, and the spec should say which one.

Granule color is a blend, not a single pigment. Each shade uses several colored granules mixed in set proportions, and the blend is what your eye reads as the roof color. Two bundles from different production runs can match on paper and still look slightly different side by side on the roof, especially in low light. That is why a spec should say whether the crew will draw from more than one lot, and why the lot number on the wrapper is worth keeping. The lot number ties the bundles on your roof to a specific production record, so if a color question comes up later, you have a number to point to rather than a memory of the sample.

Ask the crew to stage bundles so they can be laid across the whole roof at once, not stacked by slope. If the roof has four slopes and the crew installs one at a time from separate pallets, the color can shift from slope to slope. Ask how the crew plans to mix bundles, and whether the spec allows it. A roofer who has a plan will answer in one sentence. A roofer without one will tell you the color will be fine.

How St. Louis weather changes a shade

St. Louis gets long hot summers, a hail season that often runs through spring, heavy pollen, and winters with freeze thaw cycles that loosen surface material. A sun-facing slope takes more direct heat than a shaded one, so the south and west slopes often age faster in color than the north and east. A dark shingle on a south slope can look noticeably lighter in a few years than the same shingle on a north slope. That gap is normal wear, not a defect, and it is one reason to keep the full color name in the spec so you can compare the aged roof against the original shade.

Shade also changes how the roof reads from the street. Light shades reflect more sunlight, which some homeowners choose to ease attic heat, but they show algae streaking and dirt sooner. Dark shades hide dirt better but run hotter on the surface. Neither choice is wrong. The choice should be made with the house in mind, including the brick and trim colors and how much cleaning you are willing to plan for. The spec does not need to explain the choice, but it should record the color you picked so the roof can be identified later by its exact product and shade.

What it costs

Color usually does not change the labor line on a shingle roof, but it can change the material line. Some shades are stocked in full pallet quantities at the supplier, and others are special orders with a longer lead time. A quote should tell you whether the color you picked is on the base price or is an upgrade, and whether the lead time for that color matches the rest of the order. If the color is on backorder, the schedule moves, and the schedule is the part that can slip without a clear written note. Ask for the lead time in writing for the color itself, not only for the shingle product line.

Be careful with a quote that lists a color without a price difference and then bills for an upgrade later. The cleanest way to avoid that is to fix the color name in the signed contract before the order is placed. An order that changes color after the signature is a change order, and the change order clause should say who approves a substitution and at what price. Keys documents the materials and puts the scope in your hands in writing, so the color name, the lot plan, and any substitution should all appear on paper before the bundles leave the supplier.

What to ask

Before you approve the order, ask these questions and write the answers down next to the color name.

• What is the full manufacturer color name for each shingle in the order, and is it written in the spec?
• Is that color on the base price line, or is it an upgrade with a separate charge?
• What is the lead time for this exact color, and does it match the schedule in the contract?
• Will the crew stage bundles from one lot or several, and how will the shade be blended across the roof?
• If the color is out of stock, which substitute is allowed, and will you approve it in writing before it goes on the roof?
• Can you show me the lot number on the bundles when they arrive, and will you photograph the wrappers before the crew opens them?
• Will the job photo log show the bundles and the finished roof in the same light?

Keys can be reached at (314) 220-2333 to talk through the color, the lot plan, and the lead time before anything is signed. Bring the color name from your quote, the address of the house, and a photo of the siding and trim, so the conversation starts from the house and not from a memory of a sample board.
