How to Compare Roofing Estimates in the Phoenix Valley
You got two or three roofing estimates, and they look like they're for different houses. One is a single line. Another runs two pages. The totals are far apart. It's tempting to pick the lowest number and move on, but the bottom line only tells you what you'll pay, not what you'll get.
Here's how to line up roofing estimates so you're comparing the same job.

Start with the scope
The scope is the description of the work. It's the most important part of any estimate, and it's where most differences hide. A good scope tells you:
- whether it's a repair, a partial replacement or a full replacement - which sections of the roof are included (main roof, patio, garage, flat sections) - whether the old roof is removed or covered over - what material you're getting, by type and color
In the Phoenix Valley, flat patio covers and garage sections are easy to leave out of a bid. If one estimate includes them and another doesn't, the totals will never line up. Ask each roofer to list those sections by name.
If one estimate says "replace roof" and another lists each step, ask the first roofer to put it in writing the same way. You can't compare what isn't written down.

Underlayment: the layer you can't see
On tile roofs especially, the underlayment under the tile does most of the waterproofing. In the Valley's heat it wears out long before the tile does. Heat-worn underlayment is one of the most common gaps we see when two bids don't match. So for a tile roof, ask each roofer:
- Is the underlayment being replaced, or only the tiles touched? - What type of underlayment is in the bid? - Are the existing tiles being reused, or replaced?
Two tile bids can be miles apart just because one replaces the underlayment and the other doesn't. That isn't a small detail. It's the difference between fixing the problem and covering it up.

Decking and the unknowns
Nobody can see the roof deck (the wood under everything) until the old roof comes off. Some boards may be soft or damaged. A clear estimate explains how damaged decking will be handled if it's found: how it gets documented, how you'll be told, and how it's charged. An estimate that's silent on this can lead to surprises later.
Flashing, vents and edges
Leaks often start where the roof meets something else: walls, chimneys, skylights, vents and valleys. Check whether each estimate includes new flashing or reuses old pieces, and whether roof vents and edge metal are part of the job. These items don't look like much on paper, but they're where good roofs and bad roofs part ways.
Permits and HOA
A full replacement often needs a permit, depending on your city or town. Ask who pulls it and whether it's included. We pull permits where they're required.
If you're in an HOA, ask whether the roofer will help with the approval paperwork. We help with HOA paperwork, which is one less thing on your list.
Cleanup and protection
Roof work is messy. A good estimate mentions debris removal, cleanup of the yard and driveway, and how landscaping, pools and AC units will be protected. If it's not in writing, ask.
License, bonding and warranty
Before you compare anything else, confirm each contractor has an active Arizona ROC license and is bonded. Honey Roofing is licensed and bonded, ROC #360606.
Then look at the warranty. Warranties vary by material and by product, so ask each roofer what warranty applies to the materials and the work they're quoting, who stands behind it, and get it in writing.
Questions that clear things up fast
When estimates don't line up, these questions usually explain why:
- Is the old roof being removed, or covered over? - Does this include new underlayment? - How will you handle damaged decking if you find it? - Is new flashing included? - Who pulls the permit? - What's the warranty, in writing?
A roofer who answers clearly and without pressure is usually one worth hiring.

Questions
Why are my roofing estimates so different?
Usually because they cover different work. Check whether each one includes removing the old roof, new underlayment, flashing, decking repairs, permits and cleanup.
Should I just pick the lowest roofing estimate?
Not until you know the estimates cover the same scope. A low bid that skips underlayment or flashing can cost more when the roof leaks again.
What should be in writing on a roofing estimate?
The scope, the material type and color, whether the old roof is removed or covered over, underlayment, how damaged decking is handled, permits, cleanup and the warranty.
