Do you provide emergency commercial roof leak repair in Northern California?

Yes. We offer fast, reliable emergency leak service throughout Northern California. Our technicians respond quickly to stop active leaks, prevent property damage, and restore the integrity of your roof as soon as possible.

How do I know if my commercial roof needs repair or a full replacement?

Most commercial roofs show early signs of trouble long before a major failure occurs. If you’re noticing leaks, ponding water, damaged membranes, or rising repair costs, we can assess the condition of your roof and help you determine whether repairs or a complete re-roof is the smarter long-term choice.

How often should a commercial roof be inspected in Northern California?

Most commercial roofs should be professionally inspected at least twice a year, along with after major weather events. Regular inspections help you catch small issues early, extend the life of your roof, and avoid unexpected failures that disrupt operations.

Emergency Leak Service

A Membrane Built for Equipment-Heavy San Jose Properties

EPDM has been on commercial roofs for more than four decades, which means its failure modes are documented rather than theoretical. That track record counts for something on a building you intend to hold. Highland Commercial Roofing has provided commercial roofing services in San Jose for over 35 years, and we specify EPDM roofing where the roof works for a living: decks carrying dense mechanical equipment, buildings with steady technician traffic, and properties where seam count and simple repairs outweigh solar reflectance.

The membrane stays pliable instead of hardening with age, absorbs foot traffic without splitting, and takes repairs cleanly when rooftop units get swapped or added. Large sheet sizes mean fewer seams, and fewer seams mean fewer places for a South Bay winter to find a way in. The tradeoff is reflectivity, and that tradeoff belongs to the building.

How does EPDM hold up through San Jose’s rainy season?

Yes, when the details are done right. EPDM is a waterproofing membrane first, and its large sheet format reduces the number of seams a winter storm can test. Where South Bay roofs get into trouble is at penetrations and drains rather than in the field of the membrane. Flashing quality around your rooftop equipment and drainage that actually clears matter more than the material itself.

Should I choose EPDM or PVC for my facility?

PVC is the premium answer when chemical exposure is in play, which is why it lands on healthcare facilities, restaurants, and manufacturing buildings venting oils or solvents. EPDM roofing is the value answer for buildings without that exposure, offering excellent weathering and simpler repairs at lower cost. Many San Jose tech campuses run kitchen exhaust or lab ventilation that pushes the decision toward PVC. We assess what your roof is actually exposed to.

Can EPDM be installed over my existing roof?

Sometimes. A recovered assembly avoids tear-off cost and landfill disposal, but only when the existing system is dry, structurally sound, and code allows another layer. Saturated insulation underneath will destroy a new membrane from below regardless of how well it is installed. A commercial roof inspection with moisture testing determines whether recovery is genuinely available to you.

What kind of maintenance does an EPDM roof need?

Less than most, though not none. Twice-yearly inspections, ahead of the rains and again in spring, plus drain clearing and attention to seams and flashings after any rooftop work by other trades. Most EPDM roofing failures we see in San Jose trace back to a contractor who was on the roof for something unrelated. Consistent maintenance is what carries these systems over the past twenty years.

Straight Answers Before You Commit

EPDM has earned its reputation over more than forty years in the field, and for a lot of San Jose buildings it is still a smart, cost-effective choice: a proven single-ply membrane that performs well when it is specified and installed correctly. As an eight-time Guildmaster Award winner for Service Excellence, Highland has built a practice on telling clients what their roof needs rather than what they would prefer to sell.

We work across all major commercial roofing systems in San Jose, which means we have no reason to steer you. Bring us your building, your budget, and your hold period, and we will tell you where EPDM fits and where it does not. Contact us today.
