Commercial Roofing Services

Service work on a commercial roof usually begins at a piece of sheet metal. A coping joint that has opened, a counterflashing that has dropped out of its reglet, a scupper box packed with grit: these small details let water in long before the field of the membrane wears out. Each service we offer is a different answer to one question, which is how much of the roof has to be rebuilt to make that detail tight again. Sometimes the answer is a hand-formed corner patch. Sometimes it is a new roof. We would rather tell an owner plainly which one the building needs.

Leak Repair and Emergency Response

A repair starts with finding where the water enters, which is seldom where it shows. Our commercial roof repair work follows a ceiling stain back across the deck to the lap, penetration or termination that opened, then rebuilds that one detail properly instead of smearing sealant over the joint. When water is already moving through an occupied building, emergency roof repair is available at any hour, every day of the year, holidays included, and the temporary cover is set so the permanent work can follow without tearing it up.

Pasadena's winter rain is short, but the San Gabriel Mountains give Pasadena roughly six inches more rain a year than downtown Los Angeles. A drain that was fine in a dry summer finds its limit in February, which is why roof drains and scuppers deserve attention before the first front arrives.

Inspection, Surveys and Upkeep

The cheapest roof work is the work a careful walk finds early. A commercial roof inspection means probing seams, looking behind counterflashing and photographing every corner, and the written report sorts what needs attention now from what can wait for the budget cycle. Where the surface hides the problem, drone passes and infrared moisture surveys show wet insulation that no one standing on the membrane would ever feel.

A steady preventive maintenance visit before and after the rainy months keeps debris out of the sumps, re-seals the joints that moved in the heat and gives the owner a dated file to show a lender or an insurer.

Coating, Recover and Replacement

When a roof has more life in it than leaks, roof coating and restoration can reset the surface after the seams and flashings are rebuilt. When the insulation is wet or the membrane has gone brittle, a commercial roof replacement is the right answer, and an overlay is only worth discussing if the deck and insulation underneath are dry. Along the historic brick-facade blocks of Old Pasadena, the edge metal and the wall terminations can decide the scope as much as the membrane does.

Cool Roof Rules and Fire Zone Assemblies

California's energy code asks low-slope roofs to meet an aged reflectance and emittance value whenever a roof is new or a large share of it is altered, so a cool roof installation is often part of the scope whether the owner planned it or not. In the Very High fire hazard zones around the Arroyo Seco and upper Hastings Ranch, replacing more than half of a roof in a year calls for a Class A assembly. We work out which rules a given scope triggers before the first quote goes out, so the number does not change after the permit review.

Commercial Roofing Questions

What makes the same repair cost more on one building than another?

Access and hidden conditions drive the difference. A roof hatch is simpler than a corner above a lobby or loading dock that needs protection below.

Can a building need both a repair and a replacement plan at the same time?

Often. We stabilize the active leak now and record the replacement window, so urgent detail work does not hide the larger decision.

When does repair stop being the sensible choice?

When wet insulation or widespread seam failure makes repeated patches poor value. We compare repair, recover and tear-off after moisture checks and cores.

Can an occupied building stay open during a reroof?

Usually. We divide work into dry-in areas, protect entrances and equipment, and close each exposed area before leaving.
