Roofing in Glendale, California
Steep hillside properties, mature tile roofs, and a downtown core of low-slope commercial buildings.

Glendale is a hillside city, and that changes roofing in concrete ways. Steeper pitches, multi-level rooflines, limited street access, heavy tree cover in the Verdugo foothills, and runoff volumes that overwhelm undersized valleys and gutters. It also has its own building department.
KAT ROOFING CO holds CSLB license #857967 in the C-39 Roofing classification and has been in business since 2005, operating from 12348 San Fernando Rd H, Sylmar, CA 91342.
Hillside and foothill properties
Above Kenneth Road and through the Verdugo foothills, the roof work is as much about logistics as materials. Material has to be lifted or carried, debris has to come down the same way, and safety on a steep multi-level roof adds real time to the job. Anyone quoting a hillside roof at flat-lot pricing has not looked at the property.
Tree cover is the other factor. Overhanging oak and sycamore drop debris that packs valleys and gutters, holds moisture against the roof, and shortens the life of the underlayment beneath tile. Valley detailing and drainage capacity get extra attention on these homes.
Tile roofs, which Glendale has a lot of
Clay and concrete tile is everywhere in Glendale, much of it 30 to 50 years old. The tile is typically fine; the underlayment beneath it is not. The correct scope is usually to stack the tile, replace the underlayment and every flashing, and relay the tile with new broken-piece replacements — preserving the appearance of the house at a fraction of new-tile cost.
- Tile lift-and-relay with new underlayment
- Clay tile salvage and matching
- Valley and dead-valley rebuilds
- Steep-slope shingle replacement
- Gutter and drainage capacity correction
- Low-slope sections and deck-over-living-space detailing
Downtown and Brand Boulevard commercial
The commercial core is low-slope roofs behind parapets, frequently with occupied space directly below and mechanical equipment above. Those roofs get restoration coatings when the assembly is dry and full replacement when it is not, with the parapet and scupper details rebuilt either way.
