ADU Construction in Glendora
Glendora ADUs with a roof built to shed water and resist embers: Class A covering, metal gutters and screened vents, permitted and built after a fire.
A small roof still has to move a lot of water, and on a Glendora backyard unit it also has to stand up to embers. Glendora includes land inside mapped fire hazard zones, and a lot within one may need ember-resistant roof covering, gutters and vents. We start the roof drawing with where the rain goes and what the edges are made of, then build out the rest of the unit beneath it.
Moving water off a compact roof
A short roof plane collects rain fast, and with little overhang the runoff lands close to the foundation unless it is led away. We size the gutters and downspouts to the roof area and carry the discharge to a splash block, a drain line or a planted area set apart from the footing. Flashing at the wall where a porch or shed roof meets the unit gets extra care, since that joint is where leaks tend to start. A low-slope roof gets a membrane rated for it, and every penetration is booted and sealed.
Edges built against embers
On a parcel inside a mapped hazard area, the roof edge is where wind-driven embers collect. A Class A covering, noncombustible gutters with guards and vents screened with fine mesh keep them from settling or slipping into the attic. Eaves can be boxed in with noncombustible soffits. We match these details to the main house when both are rebuilt, so one structure does not carry a weaker edge than the other. Glendora's building department checks these details at plan review, and its inspector sees the roof before anything covers it.

ADU Construction in Glendora: questions
It can if Glendora permits the unit ahead of the house. Finishing the small roof and shell first gives you a dry, inspected place on the property while the main house is drawn and built, and its ember-resistant details carry over to the larger rebuild.
The package fits a Glendora unit that keeps to a single level and 500 square feet or less. Here the roof plan earns close attention, because it has to show the covering and vent details for a parcel that may fall within a mapped fire hazard area. We confirm the lot on our visit.
If the garage survived a fire, its roof and vents may need upgrading before it can house anyone. We open the ceiling to read the rafters, check the slab under the walls and look at how the roof is covered, then price the conversion against a detached unit built new.
