Commercial Roofing
Commercial Roof Replacement for North County Businesses & HOAs
There comes a point on a commercial roof where the repair log is longer than the maintenance log, and every rainy season means another emergency call. When we see wet insulation across multiple test cuts, seams failing faster than we can weld them, or a membrane that has gone brittle from years of coastal UV, replacement stops being a question of if and becomes a question of when and how.
We handle full re-roofs for strip retail, office parks, medical buildings, restaurants, and HOA common-area flat roofs across Carlsbad, Vista, San Marcos, Oceanside, and Encinitas. A California commercial re-roof is not just a new membrane, it triggers Title 24 cool-roof requirements, and we plan the assembly to meet code and cut the heat load on the building.
When you need commercial roof replacement
- Repairs are recurring in new spots every season and no longer holding
- Test cuts reveal wet insulation across a large share of the roof
- The membrane is brittle, shrinking, or has lost its top layer to UV
- Ponding has become chronic because slope or drains have failed
- You are re-roofing to meet Title 24 cool-roof rules on a permit
- An HOA reserve study has flagged the roof at end of life
- You are adding rooftop equipment the current roof cannot support or seal around
- Insurance or a buyer's inspection has called the roof out ahead of a sale
What we do
- Perform test cuts and a moisture survey to confirm what the deck and insulation are really doing
- Recommend tear-off versus recover based on code, weight, and how many layers exist
- Design the new assembly to hit Title 24 cool-roof and R-value targets
- Handle permitting and any required inspections with the local jurisdiction
- Sequence the tear-off in sections so tenants stay dry and operating
- Correct slope and add crickets or drains to end chronic ponding
- Install the new membrane, insulation, and flashings to manufacturer spec for warranty
- Register the manufacturer warranty and hand over a full closeout package
Roof types & materials
- TPO membrane systems for reflective, budget-conscious re-roofs
- PVC membrane for restaurants and buildings with grease or chemical exposure
- SPF foam recover for adding slope and insulation over a sound deck
- Modified bitumen for buildings that want a tough, multi-ply low-slope surface
- Cover-board and polyiso insulation packages sized to Title 24 R-value
- Cool-roof reflective coatings and finishes for compliance
Do you have to tear off the old roof, or can you re-roof over it?
It depends on how many roofing layers already exist and whether the insulation is wet. California code generally limits a roof to two layers, so if a second layer is already in place or moisture testing shows saturated insulation, a full tear-off is required. When the deck is sound and only one layer exists, a recover or foam overlay can be a faster, less disruptive option.
