Start your plan with the real roof problem
A worn shingle roof can lead you to ask for new shingles. So can a long repair list. Start with the work you need done. Name the slopes. Note any known leaks. Say if the old roof will come off. Then ask for a plan that shows how the new roof meets walls, edges, and vents.
A color name alone does not describe that work. A good proposal explains what stays. It explains what changes. It lists what must be checked once old layers come off. Use the checklist below to find gaps before you compare totals.
What your shingle scope should name
- Deck condition
- Underlayment and leak barrier
- Starter at edges
- Field shingles
- Flashings at joints
- Ridge caps
- Assembly-specific air plan
Layer stack from deck to shingles with separate callouts at edge, wall and ridge; air plan shown beside the stack, not as a waterproof layer.
Know what each roof layer does
The deck is the wood under the roof covering. The underlayment sits over that wood as a backup water layer. Starter strips hold the first shingle rows at the edges. Field shingles cover the wide slopes. Ridge caps finish the raised lines where slopes meet. GAF's roof-parts guide explains these jobs.
Ask the bid to name the products and where each one goes. A leak barrier is not the same as the main underlayment. If the bid only lists felt and shingles, ask about the missing edge, valley, and ridge work. Clear product names make warranty questions easier to answer later.
Plan a fair way to handle hidden deck damage
A roofer cannot see all the wood until the old roof comes off. A good bid plans for that without giving a blank check. Ask how soft or split deck spots will be shown to you. Ask what price is used for added work. Ask how you approve it, and who keeps the photos.
Also spell out removal. Does the price cover all roof layers, loading debris, and hauling it away? Is a porch or garage included? Mark those roof sections on a simple sketch. A lower bid may just cover less work. Settle these points before you pick a shingle.
Do not let flashing get lost in fine print
Flashing is the shaped metal that moves water away from roof joints. A chimney, a wall joint, a pipe, and a valley each need their own piece. Ask which flashing will be replaced. Ask which may stay. If a piece will be reused, ask why and how it was checked.
Ask the same about skylights and old roof vents. Do not let a broad promise to seal everything replace a real list of work. The best time to agree on nearby siding or chimney work is before the roof is open. Put those duties in the written scope.

Match your airflow plan to your roof type
A ridge vent is just one part of a vented attic plan. The path that brings air in matters just as much. PNNL explains that vented attics and sealed unvented attics are built in different ways. The proposal should name the current design before adding or removing vents.
Tell your roofer about rooms that are hard to heat or cool. Mention past attic moisture and any new insulation work. These are useful clues to check, not proof of a roof problem. Ask if the job includes an attic check. Ask which issues need another trade. Do not pick vents by looks alone.

Pick your real sample once the scope is set
Compare real samples in daylight next to the siding, brick, gutters, and trim that will stay. Look from a few steps back as well as up close. A small screen photo can hide the mix of granule colors. Write down the product line, color name, and sample date.
If you are choosing between three-tab and architectural shingles, compare the exact products, not two broad labels. Check that your choice is in stock before you plan around one shade. Ask how a product change affects the starter, ridge caps, install steps, and written warranty. A matching color does not mean parts work together.
Turn your checklist into one clear request
Mark each part as named in the bid, missing, or waiting for inspection. This tool groups missing items into a short list for your roofing request. It does not say whether the roof meets code. Keep unsure items listed. Do not guess that they are covered.
For a home in Peoria, the city's permit page is a good first stop for requirements. Use the real property address and the planned work. A Peoria mailing address alone does not say which office has authority. Write down who will check this, and what inspection is needed.
Treat the final handover as part of the job
Ask what you will get once the roof work is done. Useful records include the final product list, approved changes, warranty papers, and photos of parts now covered up. Agree on the cleanup area. Agree on how any concerns get listed at the final walk-through.
The next step is to ask for a shingle scope that answers your missing items. List the roof sections, the current problem, and the products you want compared. If you only need a small repair, say that up front. A good request should guide the work, not turn every issue into a full replacement.
Your questions, answered
Does every part need to be the same brand?
Follow the instructions for the chosen product and the terms of the offered warranty. A brand name alone does not prove every part fits. Ask for the named starter, underlayment, ridge cap, and other needed parts, plus written proof for any swap.
Can I keep my current roof vents?
That depends on your roof, your attic design, and the vent condition. Ask which vents stay, which get removed, and how any gaps will be fixed. Keep the air-in and air-out review tied to the whole roof system.
Should the bid cover every possible deck repair?
It should explain how unknown deck work gets handled. It may not give a final amount before the old roof comes off. Ask for a clear price rule, photos, and an approval step so hidden work does not turn into an open-ended bill.
Can I pick the color after I sign?
Set that timing in the agreement. Ask when the order becomes final and how a color or product change affects stock and price. Keep the exact product and color in the final paperwork so a look-alike item does not show up by mistake.
