The Starter Course Can Separate Two Roofing Quotes
Here is how to compare the first shingle course at the eaves and rakes before choosing a Chesterfield roofing bid.
Two roofing proposals can name the same field shingle and still describe different roof systems. One difference may be almost invisible in the paperwork: the starter course. Starter shingles form the first sealed row along the roof edge. They help secure the first full course, cover joints near the edge, and resist wind getting beneath the shingles. If one Chesterfield roofer specifies purpose made starter at both the eaves and rakes while another proposal says nothing, the bids are not yet equal.
This detail matters because the edge is where wind first tries to lift the roof covering. The eave is the horizontal lower edge above the gutter. The rake is the sloped edge that runs from the eave toward the ridge on a gable. A starter product normally has a factory applied adhesive strip positioned to bond with the shingles above it. That bond is part of the edge assembly, not a decorative extra.
Roofer comparison
Start by finding the words starter shingle, starter strip, or starter course in each proposal. Then check where the material will be installed. A line that says starter at the eaves does not necessarily include the rakes. A line that says starter around the perimeter is clearer because it identifies both types of exposed edge.
Next, ask whether the proposal calls for a manufactured starter product or shingles modified on site. Roofers have historically cut tabs from three tab shingles and turned the pieces into a starter course. That can create a covered base beneath the first row, but it does not automatically reproduce the adhesive location, dimensions, or installation instructions of a purpose made starter. If a bidder plans to cut field shingles, ask for the exact method and written confirmation that it is accepted for the proposed roof system.
The comparison should also include the manufacturer. Keys Roofing installs Atlas and Malarkey shingles, so a Keys proposal should identify the starter component intended for the selected Atlas or Malarkey assembly. A generic line such as materials included leaves you to guess whether the starter belongs to that system or is simply whatever is available on installation day.
Do not confuse starter with drip edge. Drip edge is metal installed along the roof perimeter. Starter is a shingle product placed over the prepared edge assembly. Both can appear at the eave, but they perform different jobs. A bid that includes new drip edge has not necessarily included manufactured starter. Likewise, a starter line does not tell you whether damaged edge metal will be replaced.
Placement is another useful comparison. At the eave, the roofer must coordinate the roof deck, underlayment or eave membrane, drip edge, starter, shingles, and gutter edge. At the rake, the order of the underlayment and metal can differ according to the roof assembly and applicable instructions. You do not need to design that sequence yourself. You do need the contractor to identify the materials and state that installation will follow the applicable manufacturer instructions and local requirements.
Chesterfield roofs give this small detail real work to do. Spring storms can drive wind against a gable edge. Summer heat warms the adhesive strips. Winter cold stiffens shingles, and repeated freeze thaw cycles test edges where water has found a path. Ice damming at an eave can also hold water above the gutter line. Starter does not prevent every leak or replace eave membrane, ventilation, or correct flashing, but it closes one avoidable weakness at the roof perimeter.
Do not compare only the bundle name
A field shingle name is not a complete specification. The starter course, hip and ridge material, underlayment, eave protection, flashing, ventilation, and fasteners all affect what will actually be installed. If both proposals say Atlas or both say Malarkey, that still does not establish that both contractors priced the same collection of components.
Ask each bidder to mark the starter line rather than answer with a general assurance that everything is included. A specific answer might identify the starter product, state that it runs at eaves and rakes, and confirm that it will be installed using the required fastener placement. That answer can be checked against the final contract. A verbal answer cannot.
Photographs can help before and after the work. Before tear off, wide photos show the existing eaves and rake edges, including areas where shingles have lifted or where metal has pulled away. During installation, photos taken before the first field course covers the starter can show that the specified material was placed along the edge. Ask whether those photographs will be included with the project record.
What it costs
Starter is usually a small share of a complete roof replacement, but it is not free. The quantity depends on linear feet, not only on roof area. A simple hip roof may have starter along its eaves, while a house with several front facing gables also has multiple rake runs. Two houses with the same number of roofing squares can need different amounts of starter because their perimeters are different.
This is why a low allowance can be misleading. A proposal based only on the main eave length may omit the gable edges. Another proposal may include factory starter around the full perimeter. The second number can be higher even if both roofers measured the same field area.
Ask for starter to be included in the fixed roof scope rather than left as an unnamed accessory. The proposal does not need to show the contractor's wholesale bundle price. It should make clear whether the quoted total includes the product, labor, normal waste, and installation at every specified edge.
Waste deserves a plain explanation. Starter pieces must be cut at corners, roof intersections, and changes in edge direction. Complex Chesterfield rooflines with several gables, dormers, or porch roofs create more starts and stops than a basic rectangle. That does not mean the contractor should add an unexplained charge later. It means the perimeter should be measured before the contract price is set.
If starter is absent from one bid, do not simply add a guessed retail price and call the proposals equal. The difference may include product quantity, labor, delivery, and the contractor's planned installation method. Ask the bidder to revise the written scope and total. Then compare the revised number with the other proposal.
Repair pricing is different
Starter can also matter in a repair near an eave or rake. A roofer may need to release or replace adjacent shingles to rebuild the edge correctly. The visible damaged area might be only a few feet long, but the work can involve metal, membrane, starter, field shingles, and gutter access.
Age changes the decision. Once an older three tab roof has become brittle, lifting the edge for a localized repair can break surrounding tabs. There is no single birthday that makes every three tab roof unrepairable. Exposure, ventilation, previous repairs, and shingle condition matter. A roofer should explain whether the existing material can be manipulated without causing a larger damaged area.
What to ask
Use the same questions with every bidder. The goal is not to test roofing vocabulary. It is to turn a vague accessory into a comparable written specification.
- What exact starter product is included? Ask for the manufacturer and product name, not just a promise that starter will be used.
- Does it run along both eaves and rakes? Have the contractor identify every roof edge included in the price.
- Is any part made by cutting another shingle? If so, ask for the method and why it is suitable for the specified assembly.
- How is the starter coordinated with drip edge and eave membrane? The answer should distinguish these materials instead of treating them as one item.
- Does the total include all perimeter footage? This is especially important on homes with several gables, attached garages, porches, and lower roof sections.
- Will installation photos show the starter before it is covered? The useful photograph is taken while the edge remains visible.
- Who resolves a conflict between the proposal and manufacturer instructions? The written contract should not require you to accept an improvised substitution.
Also ask who will obtain the required permit and which municipal desk applies to the property. St. Louis County contains many municipalities, and permit administration is not identical from one address to another. The permit question does not replace the starter specification, but it shows whether the bidder has checked the actual job location rather than treating every county address as the same jurisdiction.
If a proposal says only complete roofing system, request one added sentence before signing: the named starter product will be installed at all eaves and rakes included in the measured roof perimeter. If the contractor intends a different method at a low slope section, porch tie in, or unusual edge, have that exception identified separately.
Keys Roofing can inspect the roof edge, measure the eaves and rakes, and put the proposed Atlas or Malarkey starter component into a written scope. Homeowners in Chesterfield and the greater St. Louis area can call (314) 220-2333 to request an inspection and a proposal that identifies the perimeter materials before the work is scheduled.
Have Keys Roofing look at it instead
A written scope from Keys Roofing covers every line on this page, because this page is a description of what a scope should contain. Compare it against the others line for line, which is the entire point.

If an insurance claim is part of your situation, the claim stays in your name and in your hands: under RSMo 407.725 a Missouri roofing contractor may not represent or negotiate a homeowner's insurance claim, and Keys does not. Keys documents what is on the roof and meets the adjuster there as the contractor.
