Best Roof Repair in Phoenix, AZ

Apex holds GAF Master Elite, CertainTeed Select ShingleMaster, and Owens Corning Preferred certifications — the elite tier of all three major manufacturers' contractor programs. Each requires annual re-qualification, proof of current general liability and workers' compensation insurance, background checks on the company principals, customer satisfaction verification, and demonstrated adherence to manufacturer installation standards. Fewer than 3 percent of roofing contractors nationwide hold even one of these designations; holding all three is rare.

The warranty covers defects in installation workmanship — improper nail placement, inadequate flashing installation, incorrect shingle overlap exposure, and sealant application failures. It does not cover storm damage to the repaired area that exceeds the rated wind or impact resistance of the installed material, or damage caused by tree limb impact or other external forces. Claims are handled directly through Apex — not through a third party — and we respond to warranty service calls within 48 hours.

We start from the interior — identifying the wetted area, tracing the water stain to its highest point, and mapping the travel path from interior to exterior. We then inspect the exterior systematically: every penetration within 20 feet of the interior damage point, all valley intersections, the full ridge and hip line, drip edge condition, and flashing at every wall-to-roof junction. For elusive leaks, we use a controlled water test — a hose applied systematically from the eave up to isolate the entry zone — before attributing the leak to any specific component.

Most architectural shingles require 4 nails per shingle in the designated nail strip zone, spaced according to manufacturer spec (typically 1 inch from each end and evenly distributed in between), driven flush — not overdriven and countersunk, not underdriven and proud. In high-wind zones (coastal areas, mountain exposures), 6-nail patterns may be required by code. The nail strip is the reinforced zone designed to distribute wind load — nails driven above or below it compromise the mechanical holding force and can fail the wind speed rating by 40 to 60 mph.

Ice-and-water shield (also called peel-and-stick underlayment or self-adhering membrane) is a rubberized asphalt product that bonds directly to the decking and self-seals around fasteners, preventing water from penetrating even when shingles are lifted or missing. IRC code requires it at all eaves extending at least 24 inches inside the heated wall line, in all valleys, and within 24 inches of all roof penetrations in areas with design temperatures at or below 25°F. Best practice — and Apex's standard — extends this to all valleys and penetrations regardless of climate zone.

Ask for the specific underlayment product being used (synthetic felt vs. ice-and-water shield at vulnerable zones), the nail pattern and fastener specification, whether the pipe boots are being replaced or re-sealed, and whether any surrounding shingles are being re-nailed or replaced to restore the bond strip. A quality repair quote will answer all of these questions specifically. A quote that can only describe the work as 'fix the leak' without component-level detail is not a quality scope.

We can discuss flexible arrangements on a case-by-case basis — ask when you book and we'll outline what's available.

We're competitively priced and fully transparent — our quotes itemize labour and materials so you can compare accurately.

In most cases a targeted repair extends roof life significantly at a fraction of the cost — we'll tell you honestly if replacement is the better value.

We inspect (exterior + attic), diagnose the root cause, present a written repair plan, complete the work, and send you before/after photos. Most repairs are done in a single visit.
