What we write about, and why

Every post here answers a question Pomona property owners actually ask before they hire anyone — what work costs, which materials are worth the upcharge, how long a job really takes, and the shortcuts that look fine for two years and then do not.

The writing comes from the same people doing the work in Pomona, CA and the Pomona Valley, which is why the numbers are specific and the advice sometimes tells you not to spend money.

Need help now rather than reading

Skip the articles and go to the page for what you need — each one covers pricing, scope and how to start:

Roof Replacement & Phasing in Pomona — A replacement in Pomona is usually a decision about sequence, not product. Most roofs we tear off here have been patched for a decade, so the real question is which planes have to go this year and which can honestly wait.
Roof Leak Diagnosis & Repair in Pomona — A leak call here is a diagnostic before it is a repair. Pomona takes most of its rain in a handful of winter weeks, so a roof can fail in March and say nothing about it until the following December.
Storm Damage Restoration in Pomona — Most storm calls in Pomona arrive during a January atmospheric river, and a fair share of them are not storm damage. They are a roof that has been failing quietly for years and finally met four inches of rain in two days.
Hail Damage Assessment in Pomona — This is the page where we argue against the product. Hail is uncommon in the Pomona Valley, and most roofs we are asked to inspect for hail damage here turn out to have something else wrong with them entirely.
Wind Damage Repair in Pomona — Wind losses in Pomona almost never start in the middle of a roof. They start at an edge that was already weak: a rake with no drip edge, a starter course nailed too high, or a previous patch bedded in cement instead of fastened down.
