Major lending institutions trust ASA for pre-loan due diligence and ongoing collateral monitoring across commercial mortgage portfolios.
Commercial REITs
Real estate investment trusts managing retail, industrial, and mixed-use properties rely on our data to drive capital allocation and defend valuations.
Property Managers
National and regional property management firms use ASA to standardize roof maintenance programs and reduce emergency repair spend year over year.
Institutional Owners
Insurance companies, pension funds, and government entities depend on our independent assessments when the numbers need to hold up in court or before regulators.
Independent advice from a firm with no contractor relationships to protect.
Alan Stevens & Associates was founded on a simple premise: roof consulting is most valuable when the consultant has nothing to sell but expertise. We do not install roofing. We do not manufacture materials. We have no preferred contractor network collecting referral fees.
That independence is why the nation's largest banks call us for pre-loan due diligence. When the assessment has to hold up under scrutiny, the assessor cannot have a conflict. Our clients know that every recommendation comes from field data and thirty years of pattern recognition, not from a sales commission.
"A roof report that cannot survive due diligence is not a report. It is a liability. We write every assessment as if it will be read by the opposing counsel, the insurance adjuster, and the board of directors. Because sometimes it is."Alan Stevens & Associates
