Confirm the location

Use the full property details when calling; proximity to the crossing does not establish provider availability or a branch location.
Information for a low-slope roof enquiry
If a flat roof has standing water, describe where it collects and how long you have observed it without walking onto the roof. The inspection should consider drainage, membrane condition and any sagging rather than promise a sealant-only solution. Ask whether the proposed scope addresses the reason water is accumulating.
Have the manager identify the membrane type if known, the approximate affected area and any existing warranty. Roof access and fall protection are the contractor’s responsibility. Ask whether the scope includes seams, perimeter details, drains and equipment penetrations, and whether any separate trade must be involved. Our commercial flat roof repair guide explains the relevant inspection and repair questions.
What happens when you call
For the Lancaster roof leak referral process, start with our main service guide or call (626) 910-2558. Describe the property, leak timing and any immediate access concerns. Ask the person taking the call to identify the independent provider and explain the next step. Attendance, repair scope and pricing are subject to that provider’s confirmation; no arrival time or free inspection is promised.
Keep clear of wet electrical fixtures, sagging ceilings and unsafe roof access. If a situation presents an immediate danger, move away and contact the appropriate emergency service. Do not climb onto the roof to collect information for the call.
