💬 FAQs:

Do I need an engineer letter for a tile re-roof in Boulder?

Yes — both City and County require documentation verifying that the roof framing can handle tile dead loads, and that the attachment method meets uplift pressures.

What if I don’t know my roof slope or underlayment yet?

We can provide preliminary calculations and finalize your letter once your contractor confirms product selections.

Is this valid for the 2024 City of Boulder code update?

Yes — we confirm permit submittal date and apply either ASCE 7-16 or 7-22 depending on when you’re applying.

Do you sign for Boulder County?

Yes — all letters are issued by a licensed Colorado Professional Engineer and formatted for both jurisdictions.
