Let’s Look at Your Roof Together

Allied Construction works with property managers and building owners across the Bay Area. An inspection is the first step toward knowing which commercial roofing service fits your building.

A Commercial Roofing Company Built Around the Long Term

Allied Construction has been a commercial roofing company across Northern California for over two decades, and the way our commercial roofing service is structured reflects that.

Property managers rarely need just one roofing service over the life of a building; a new install eventually needs maintenance, maintenance eventually surfaces a restoration candidate, and every roof will need a leak addressed at some point. ACS structures our commercial roofing services so all of that stays under one relationship rather than resetting the vetting process every time a different need comes up.

  • Every System, Self-Performed

    ACS installs and maintains TPO, PVC, acrylic, metal, tile, and shingle systems directly, without subcontracting the work out. That range means the recommendation you get is based on what your building needs, not on what’s easiest to sell.

  • A Maintenance Relationship That Feeds Everything Else

    Property owners on an ACS roof maintenance plan get priority scheduling if a leak comes up, and they’re usually the first to know when a roof is approaching the point where restoration makes sense. The relationship is what makes the timing work in your favor instead of against you.

  • Work That Earns the Next Referral

    ACS completed a 120,000+ sq ft, multi-year roof restoration for Safeway and a 25,000 sq ft Carlisle RapidLock TPO replacement at Sutter Health’s Novato Community Hospital, two very different buildings that demonstrate both the scale a national retailer needs and the standards a hospital campus requires.
