Read an EPDM Attachment Proposal

If you already have a written home-repair proposal naming Elevate’s U.S. commercial EPDM system, use this guide to understand its wording and request clarification. It does not establish residential suitability, availability, compatibility or fit for your home. Without that exact proposal context, treat this as a commercial-system reference.

Elevate describes EPDM as synthetic rubber in a single-ply roofing membrane; here, “membrane” means the roof-covering sheet. Systems

Ballasted insulation and membrane lie loose, held by river-washed stones or concrete pavers. Slope, height and structural deck may limit ballasted systems; deck must support ballast.

Mechanically attached: plates and fasteners or adhesive secure insulation to the deck; seam plates and fasteners join membrane sheets. Adhered: insulation is fastened or adhered to the deck; adhesive and seam tapes bond membrane over it.

Roof design, condition, location and building use influence selection; Elevate’s overview is high-level. Overview

Details that can change the next step

Read what the document actually says

Create one column per proposal. At the top, copy its title or number and its date or revision if supplied. Keep the original document so a later reply can be linked to the version it clarifies. Write “not stated” for a missing entry; do not fill it from another bidder’s document.

Copy the named system, stated attachment method and complete assembly exactly as written. Keep the preparer’s wording rather than translating a short label into a fuller description yourself. Beside it, record whether the document supplies an explanation or points to another document. A blank is an open question, not an answer.

Ask for a written explanation

Ask the proposal preparer: “Please identify everything your proposal includes, explain the project-specific basis for the choice, and name who established that basis. Which document supports your explanation, and which parts still need qualified review?” Request a written reply tied to the proposal version. This asks for the preparer’s basis; it does not independently verify it.

For example, use blanks: “Proposal A [title/date] says [exact wording]; Proposal B [title/date] says [exact wording or ‘not stated’]. Please explain what each description includes and identify the document and revision behind your answer.” Do not substitute a fictional product or invented value to make the example look complete.

Keep unanswered differences open

Add each reply, its date and the person who supplied it to the corresponding column. Preserve any revised proposal alongside the original. If the replies still describe different work, ask the preparers to clarify that difference before treating them as comparable. Leave missing or conflicting explanations unresolved. These definitions help you ask precise questions; they do not choose an option or replace qualified assessment. Do not access the roof or alter anything to fill gaps.
