Start with what the opening note of the issued Section 07 31 13 asks the drawings to show: the roof pitch, the crickets and flashing at chimneys, and an eave and rake corner detail with the underlayment, drip edge, starter strip, shingle exposure, courses, and fastener placement. Then check that the underlayment and eave protection paragraphs kept match the slope, climate, and wind on the drawings, that the shingle type agrees with the nailing, valley, and warranty choices, and that ridge vents, intake vents, and flashing at walls, pipes, and chimneys are detailed.
Assemble the review package
Gather the roof plan with the pitch of every plane, ridges, hips, valleys, chimneys, and penetrations, the eave, rake, ridge, valley, roof-to-wall, and chimney details, the building and wall sections through the eaves with the exterior wall line and overhangs, the attic sections with insulation, baffles, soffit or eave intake vents, and the ridge vent, the plumbing and mechanical roof penetrations, the structural general notes with the design wind speed and roof deck, the exterior elevations and color or finish schedule, the climate zone, hail exposure, and environmental severity classification from the design analysis, any existing roof survey for reroofing, and the issued Section 07 31 13 with Sections 07 60 00, 06 10 00, and 02 41 00. Follow one roof plane from the eave over the ridge and into a valley before assuming the others match.
WBDG publishes UFGS 07 31 13: Asphalt Shingles as a public guide-specification reference (accessed November 13, 2026). Use your project’s issued specification and amendments for the actual comparison; the guide specification does not automatically govern your project. The checklist below is an original suggested review workflow, not a reproduction of the UFGS requirements.
Eight checks to run against the issued set
Use one record per location or system. The CSV contains the same eight prompts plus fields for source revisions, observed evidence, the review owner, the decision, and closure references.
| Check | Sources to compare | Question to resolve |
|---|---|---|
| What the drawings must show | Opening drawing note (pitch of the roofing; crickets and flashing at chimneys; eave and rake corner detail with underlayment, drip edge, starter strip, exposure, courses, and fastener placement) + Ventilators note (drawings detail the ridge vent type) + Chimney Flashing note (delete unless a chimney is indicated; coordinate crickets and metal flashing with Sections 06 10 00 and 07 60 00) + roof plan, eave and rake details, chimney details | Does the roof plan give the pitch of every plane, including porch roofs, dormers, and additions, does the eave and rake corner detail show each layer in order with the exposure and fastener placement, is the ridge vent type detailed, and is the chimney paragraph kept only where a chimney is drawn, with the cricket shown on the roof plan and detailed? |
| Underlayment by slope, climate, and wind | Underlayment notes (maximum exposure not recommended on lower slopes; self-adhering or two layers of synthetic underlayment in cold or high-wind locations, with a leak barrier at eaves where synthetic is used in cold areas; a separate January temperature criterion for choosing the low-slope paragraph) + steep-slope paragraph (one layer of self-adhering, one or two layers of synthetic; leak barrier bracket; cap nailing) + low-slope paragraph (one layer of self-adhering or two layers of synthetic; starter sheet and laps written for two-layer coverage; head laps both deferred to the manufacturer and fixed) + roof plan pitches and design wind speed | Does the underlayment paragraph kept cover the slopes on the roof plan, and where the building has both slope ranges, are both paragraphs kept and each plane identified, does the underlayment kept follow the cold-climate and high-wind selection in the note, which January temperature criterion does the project use, since the notes use a January mean in one place and an average daily January temperature in another, and do the low-slope laps apply when one layer of self-adhering underlayment is chosen? |
| Eave protection, drip edges, and starter strips | Leak barrier sentences in both Underlayment paragraphs (eave protection extending up the slope past the interior face of the exterior wall) + Eave Flashing paragraphs and notes (self-adhering strips to a different point inside the wall; low-slope option of cemented underlayment or membrane to another point, with a slope bracket that also offers the steep-slope range; neither paragraph where eave flashing is not commonly provided) + Drip Edges and note (Section 07 60 00; on the deck at eaves and over the underlayment at rakes; nail spacing bracket for high wind) + Starter Strip bracket + eave detail and wall sections with overhangs | Since eave protection appears in both the Underlayment and Eave Flashing articles with different extents, which one does the eave detail show, does the membrane reach the point the kept paragraph names, measured from the interior face of the wall drawn on the wall section and not from the fascia, is the drip edge drawn under the eave membrane at eaves and over the underlayment at rakes, does the starter strip bracket match whether eave flashing is used, and is the high-wind nail spacing chosen where the wind criteria call for it? |
| Shingle type, weight, fire, wind, and impact | Shingles paragraph (“square tab, strip” unbracketed, then three-tab and architectural weight options, algae-resistant, UL 2218 Class 4 impact resistant, polymer modified; UL 790 Class A; ASTM D3161/D3161M Class F and ASTM D7158/D7158M Class H kept together in one bracket) + notes (weight by shingle type; polymer modified in ESC C3 through C5; impact resistance in severe hail areas; ASCE 7 high-wind installation; Class F and Class H as options for different wind speeds; no high-reflectance colors near airfields) + structural wind criteria + finish schedule | Which shingle does the project intend, since the square-tab strip wording stays even when architectural laminated shingles are chosen, does the wind class kept match the design wind speed in the structural notes, given that the note describes Class F and Class H as alternatives while the paragraph keeps both, is impact resistance kept where the site is hail-prone and polymer modification considered in the more severe ESC classes, and does the finish schedule name the same shingle and a color that suits an airfield location? |
| Exposure, nailing, and the high-wind items | Shingle Courses note (exposure from the manufacturer’s bundle instructions) + item b (a fixed nominal exposure and nail count and placement; deleted in the higher wind conditions) + item c (manufacturer’s fastener count and location; cut shingles) and item d (first course sealed with roof cement) + Shingles note (high-wind installation may need more nails per shingle) + Application (manufacturer’s instructions, or NRCA 5005 if kept, govern where they differ) + eave and rake corner detail with fastener placement | Is item b deleted and items c and d kept where the wind speed and eave height meet the note’s condition, does the corner detail take its exposure and nailing from the manufacturer for the chosen shingle, since item b fixes an exposure and nail count written for strip shingles, and with the Application article letting the manufacturer’s instructions override the section, which governs where the detail and the instructions differ? |
| Hips, ridges, valleys, and ridge vents | Hip/Ridge and Starter Shingles (manufacturer’s pre-made pieces; no cutting from strip shingles) + Valleys note (open metal preferred with strip shingles; closed cut allowed with architectural shingles; no woven valleys with laminated shingles) and bracket (contractor chooses closed cut, woven, or open metal) + closed cut, woven, and open sheet metal valley paragraphs (self-adhering lining; metal from Section 07 60 00; a cement band “along open metal gutters”) + Ventilators note (ridge vent type on the drawings; aluminum ridge vents in Section 07 60 00; intake and exhaust balance; a vapor retarder alternative) + ridge vent products + attic sections and soffit vents | Does the roof plan or a valley detail fix the valley type, and if the contractor’s choice is kept with laminated shingles, has the woven option been removed, does the ridge vent detail match one of the two vent products or an aluminum vent in Section 07 60 00, do the attic sections show eave or soffit intake vents and baffles in the balance the note describes, coordinated with the attic insulation, and does the “open metal gutters” wording in the open valley paragraph mean the valley flashing? |
| Flashing at walls, pipes, and chimneys, and single source | Single Source (shingles, flashing, and accessories from the same manufacturer as one system) + Drip Edges, Open Sheet Metal Valleys, Stepped Flashing, Vent and Stack Flashing, and Chimney Flashing (metal from Section 07 60 00; self-adhering membrane under step flashing; flange set in roof cement; treated wood crickets from Section 06 10 00; asphalt primer on masonry) + roof-to-wall details, plumbing vent and exhaust plans, chimney details | Do the roof-to-wall details show step flashing with the self-adhering membrane under it and a counterflashing or the wall’s weather barrier lapped over it, are plumbing vents and exhaust penetrations located clear of valleys and shown with pipe flashing, and since Single Source asks for flashing from the shingle manufacturer while every metal flashing paragraph sends it to Section 07 60 00, which does the project intend? |
| Unused products, warranties, reroofing, and the information card | Mineral-Surfaced and Smooth-Surfaced Asphalt Roll Roofing (specified; no application paragraph uses them) + Manufacturer’s Warranty note and bracket (term by shingle type; algae resistance in humid climate zones) + algae-resistant bracket in Shingles + Contractor’s Warranty + Installer’s Qualifications + reroofing note (avoid reroofing over more than one existing layer) and demolition note (salvage for recycling in Section 02 41 00) + Information Card (plies, insulation and cover board, tapered insulation) + existing roof survey | Where do the roll roofing products go, or should they be deleted, does the warranty term kept match the shingle type chosen, is algae resistance kept in both the Shingles paragraph and the warranty for humid climate zones, on a reroof do the drawings say whether the existing roofing is torn off and how many layers exist, with any salvage carried in Section 02 41 00, and which of the information card’s membrane-roof items apply to a shingle roof? |
Worked example: a cold, windy reroof with a low-slope porch and laminated shingles
Illustrative example: a reroof of a two-story wood-framed family housing building at a cold, high-wind coastal installation replaces three-tab shingles with architectural laminated shingles. The main roof is a steep gable and a low-slope porch roof dies into the front wall. The issued Section 07 31 13 keeps only the steep-slope underlayment paragraph with one layer of synthetic underlayment and no leak barrier, keeps Shingle Courses item b, keeps both wind classes, keeps the contractor’s choice of valleys, and keeps the warranty term the note gives for three-tab shingles. The roof plan gives no pitch for the porch, the eave detail stops the ice barrier short of the interior face of the wall, the porch roof-to-wall detail shows a continuous metal counterflashing with no step flashing, and the attic section shows a ridge vent with no soffit intake.
Ask the architect to give the porch pitch and keep the low-slope underlayment paragraph for it, to extend the eave protection on the detail to the point the kept paragraph names, to detail step flashing with membrane at the porch wall, to add soffit intake vents and baffles, and to choose the valley type. Ask the specifier to add the leak barrier for the cold climate, to delete item b and keep items c and d for the wind, to confirm the wind class against the structural wind speed, to edit the square-tab wording and the warranty term for laminated shingles, to resolve Single Source against Section 07 60 00, and to delete the roll roofing or say where it goes.
Avoid a false conflict
Section 07 31 13 covers asphalt shingle roofing on sloped wood decks with its underlayments, membranes, and ridge vents. Metal drip edges and valley, step, and chimney flashing follow Section 07 60 00 and the flashing guide, crickets and decking follow Section 06 10 00, attic insulation follows Section 07 21 16 and the blanket insulation guide or Section 07 21 23 and the loose fill guide, slate roofs follow Section 07 31 26, metal roofs follow Sections 07 41 13 and 07 61 14 and their guides, and tear-off and salvage follow Section 02 41 00, so check those before calling a requirement missing. The section names ASCE 7 only in its notes and relies on the wind classes and the manufacturer’s high-wind instructions, so check the structural wind criteria separately. Some of the section’s own wording needs resolving: square-tab wording stays with laminated options, the two wind classes sit in one bracket, item b fixes an exposure the note leaves to the manufacturer, the notes use two January temperature criteria, the low-slope laps are written for two-layer coverage, eave protection is specified twice with different extents, Single Source conflicts with Section 07 60 00, roll roofing has no use, woven valleys can be chosen with laminated shingles, and the information card lists membrane-roof items. Ask the specifier which wording the project intends before treating a difference as a design conflict.
When requirements disagree, follow the project’s document-control and clarification process. Do not assume that drawings always override specifications, or the reverse. Identify the exact sources and request an authorized decision.
Close the issue across the affected documents
Record the location or tag, drawing and specification references, issue dates, observed difference, and the decision needed. Assign an owner and keep the item open until the response identifies the governing requirement. Check the revised drawings and specification references together; a response email alone may leave the issued package inconsistent.
For the overall process, use the guide to drawing and specification conflicts. Mark an inapplicable checklist row with a reason, and distinguish a verified correction from a question that still needs design information.
