Leak response, repairs and phased replacements for Class A and B office buildings, medical-office mixes and corporate campuses.
The short answer
CRSA is a San Antonio commercial roofing contractor for office buildings, from small professional buildings to Class A towers and corporate campuses. We repair, coat and replace TPO, PVC, modified bitumen and metal roofs across Bexar and surrounding counties, protect tenant suites, phase work around business hours and answer a live 24/7 leak line.
Office buildings we roof (building types)
Office tenants notice two things: noise and water. These habits keep both away from them.
Crane lifts and loud work before 8 am or on weekends, quiet work during the day.
Ceiling tiles, servers and furniture protected below any open zone.
Notices for tenants and a single update for the property manager.
Cooling towers, RTUs and penthouses flashed and protected properly.
Photo reports and roof maps for owners, lenders and building engineers.
Badges, elevator and loading dock bookings and security procedures.
From one wet ceiling tile on the fifth floor to a full tower re-roof.
Live 24/7 line, crew on site within 4 hours, dry-in and interior protection coordinated with the building engineer.
TPO, PVC or mod-bit replacement in zones, timed around business hours.
Cooling towers, RTUs, elevator penthouses and pipe penetrations flashed to detail.
Silicone over sound roofs to add 10 to 15 years and lower cooling loads.
Copings, through-wall flashing and expansion joints rebuilt.
Twice-yearly inspections with reports for owners and lenders.

Our usual pick for office roof replacement
Why it fits: White and reflective, cutting cooling loads on sunny office roofs, and welded with hot air instead of flame.
Watch out: Add walkway pads; HVAC techs walk office roofs often.
For busy mechanical roofs
Modified bitumen roofing details
Why it fits: Multiple plies stand up to constant service traffic around cooling towers and RTUs.
Watch out: Specify cold-applied or self-adhered over occupied floors.
Near cafeterias and cooling towers
Why it fits: Resists grease from tenant kitchens and chemical drift from cooling towers.
Watch out: Costs more than TPO; often used only in exposed zones.
Extends roof life between leases
Why it fits: Quiet, fast and no tear-off over tenants.
Watch out: Only on dry roofs; confirmed with a moisture scan.
For sloped and visible roofs
Standing-seam metal roofing details
Why it fits: Long life on sloped office roofs, entry canopies and architectural features.
Watch out: Needs slope; not used on flat tower roofs.
