When is a Mesa shingle roof past repair?

Once granules are gone and the fiberglass mat shows across whole planes, patching stops working. That is the stage this Mesa roof reached, so we replaced the field instead of adding another patch.

Can a shingle roof and a flat section be done together?

Yes, and they should be. The shingle-to-low-slope transition is the most common leak point, so we tore off the shingle field, stripped the failed coating layers on the flat section, and rebuilt the tie-in as one detail.

Who re-flashes the HVAC curb during a Mesa roof replacement?

Our crew does. On this project the curb flashing had cracked out and was leaking, so it was rebuilt with a new termination bar and sealant as part of the roof.

Is this damage covered by insurance?

Not usually. Every failure here was age and UV driven rather than storm driven, which is a homeowner-funded replacement. We say that up front instead of filing a claim that gets denied.

3-tab asphalt shingle field + coated modified-bitumen low-slope section

Findings

3-tab shingle field is fully at end-of-life, severe granule loss across every plane exposing the fiberglass mat, the point where UV starts eating the asphalt directly.
Dozens of missing and lifted tabs across the main slopes, with prior handyman shingle patches slapped over the failures instead of proper repairs.
Failed HVAC curb flashing on the low-slope tie-in, old sealant cracked out, penetrations exposed, active leak path straight into the ceiling below.
Coated modified-bitumen flat section has multiple generations of patch coatings peeling apart, cracking, and delaminating from the substrate.
Vent boots and pipe jacks on the shingle field are dry-rotted and no longer sealing around the penetrations.
Every failure mode we found is age-driven, not storm-driven, this roof is past its service life and needs a full replacement, not another round of patches.

Our recommendation

Full tear-off of the shingle field down to the deck, replace any rotted sheathing, new synthetic underlayment, ice-and-water at eaves and valleys, new architectural shingles, all new pipe jacks and vent boots. On the low-slope section: strip the failed coating layers, prime the substrate, install a fresh 2-coat elastomeric system, and re-flash the HVAC curb properly with new termination bar and sealant.
