Questions and Answers

11 Will there be an inspector onsite at all times to inspect work before it is covered by the next step? If not…then what is protocol? Inspectors will be on site during specified work times. 2

Do you want a class 3 or class 4 shingle?

- This makes a big difference in both price and warranty. It says in the language “class 3 or 4” , but the approved shingle you cite in the specs, the GAF Timberline HDZ is indeed a class 4. I recommend that you go with a class 4 shingle, Owens Corning Flex or Malarkey Legacy would be my choices. I strongly advise against the Malarkey Vista, as it is a class- 4 shingle in name only, and only technically meet class 4 specs. It is important that you specify on this “Vista” thing due to the price point basically being the same as a class 3

Either Class 3 or Class 4 impact resitance is acceptable as long as all other specifications and warranty conditions are met. 2

Nails: The specifications call for “Hot dipped galvanized nails”. These nails only come in ring shank and are almost twice the cost of the industry standard which is “electro galvanized”.

- Whether you mean to use hot-dipped galvanized or electro-galvanized are you allowing us to install with air nailers, or are we expected to be nailing by hand?

Seems like a dumb question, but I have indeed bid government jobs where hand nailing only was permitted. Are there currently ring-shank nails in the roof? If so, it will make a difference in the labor for removal.

Use hot dipped, annular tread (ring shank) as specified. Air nailers are acceptable unless specifically not allowed by your choice of roofing manufacturer. We are unsure of existing nails used.

According to language in specs Part 3 “execution”, Pipe boots and drip edge need to be set in a bed of roof sealant or adhesive. Is this truly what you want?

-In the residential realm, this is unheard of…its total overkill. Drip edge is just nailed on and pipe-boots, are at best, lined with Ice and Water shield and attached to deck using nails which are sealed after install. While on the subject of drip-edge, “gutter apron” would be a better option along the eaves only in that it is designed more readily to receive gutters.

Roof sealant is required as specified. Gutter aprons may be used in lieu of drip edge along eaves. 2

The specs say to lay the 1st course of shingles flush with the drip edge;

however, the industry standard is to allow the shingle to protrude past the drip edge ¼” to ½” to allow water to shed into the gutters more efficiently. Would it be acceptable to install the 1st course of shingles per industry standard?

Yes, shingles should overlap drip edge 1/4" to 1/2". 2

Items like dabbing every piece of ridge cap with sealant and caulking every cut shingle where it butts into another seem like overkill and costly. Would it be acceptable to forgo these items?

No, we intend the sealant to be applied as specified. 2

Specs call for ice and water shield to be applied going up the rakes from edge extending 2 ft beyond the plane of the inside of the exterior wall….and then applying regular synthetic paper beyond that. This serves no real purpose and if you want to really do it this way then….why not just use ice and water shield on the whole roof? Or, go by the industry standard and use ice and water shield along the eaves as per code and use synthetic paper as it would be normally used on the rakes?

- Having ice and water shield over the entirety of the roof will basically give you a sort of roof beneath the roof and basically forms a seal around every nail that penetrates it.

Install ice and water shield in all areas specified in SECTION 07 31 13 - 3.03. 2

Do you want valleys to be open or closed? Specs say “open”, but pics show closed valleys. Which would you like? If closed, do you want only ice and water shield in the valleys or valley metal as well?

Open as specified. 2

The specs call for a 2” wide bead of caulk around the entire perimeter of the roof between the shingles and the deck. However, there is not a caulking gun that shoots a solid 2” wide bead of caulk.

Impossible to seal shingle directly to deck due to the fact that there will either be ice and water shield in the way or synthetic paper. If indeed this is to be done then it could only be done directly to the drip edge on the rakes and would have to be adhered to the ice and water shield on the eaves, which may work, but is definitely not according to industry standards. I feel strongly that this step or steps could be eliminated by simply using ice and water shield over the whole roof.

Caulking gun nozzles are available in 2" however does not need to be a single bead. Our intent is to apply between shingle and the layer below the shingle.

In most cases this will be shingle to ice and water shield. -CL

20 What about ridge cap? Specs say that ridge is to be modified and ridge cap installed, but I didn’t see that in the work description. Please clarify. See SECTION 07 31 13 -3.03 F & J . 2

Material, fastener and trim details are covered in SECTION 07 42 93.

Fascia: What color? Aluminum or Steel? Textured or Non-textured? Fasteners?

And in what fashion are you wanting it fastened? Can we buy it pre-made or do we need to bend it on site? 29 guage is standard for steel, do you want it heavier? If so, could be a special order item? Underlap… ¾”, 1” or 1-1/2” ? All this is important to know in case we’d have to special order?

Color will be Dark brown/bronze in general, specific color to be selected by Government through submittal process. Min. 24 ga. Aluminum, Textured, attach with color matching fasteners per SMACNA or facscia manufactures recomendations. Existing facia is approx. 7" tall with 1" underlap (field verify).

23 Is there an official SOW? If so I haven’t seen it. Please advise. There is no Statement of Work for this requirement. The project drawings and specifications prescribe all work to be completed. 2

24 Delivery trucks and drivers allowed on site as long as the contractor is there? See SECTION 01 10 00 for site entry details. 2

25 Will our gutter subs be allowed to come on a different day than everyone else? See response to Question #56. 2

We anticipate exisitng baffles to be present. 2

30 Will the existing gable vents need to be sealed off? No. 2

31 Do we have to use the Attachment 7 specifically to provide past performance?

If yes, please consider extending the due date to allow additional response time.

Please use Attachment 7: Past Performance Reference Sheet to the maximum extent possible as it is the preferred document for providing the requested past performance information; however, the Government will accept other similarly formatted documents so long as the information required to establish recency and relevancy is provided. Additionally, the proposal due date was extended to 05 February 2026 in Amendment 1 (issued on 15 January 2026).
