Most NM homes have undersized gutters that overflow every monsoon. That water rots fascia, erodes stucco, and eventually finds a way under the drip edge into the deck. I audit sizing, slope, and grading — and give you a scope that stops the damage before it hits the roof.
Tributary area calculated per downspout
SMACNA-standard sizing compliance check
Slope, hanger spacing, and seam integrity audit
Splash-zone erosion and foundation grading survey
Downspout extension and daylighting review
Written scope with materials list any qualified installer can bid
Full walk with gutter and downspout inspection. Tributary roof area calculated per downspout (SMACNA method). Slope measured with a 4-foot level at multiple points. Hanger spacing, seam integrity, and fascia condition documented. Downspout outflow and daylight-vs-underground routing inspected. Splash-zone erosion and foundation-grading photographed. Written report with per-run sizing recommendation and installer-ready materials list.
NM homeowners with monsoon overflow at gutter corners. Owners with fascia rot, stucco erosion, or foundation cracks. Buyers under contract on homes with visible drainage issues. Property managers evaluating pre-monsoon prep across rental portfolios. Homeowners quoted for a full gutter replacement wanting a sizing second opinion.

On any roof with more than 400 sqft of tributary area, yes. NM monsoon cells drop 1–2 inches per hour — that's 250+ gallons off a small roof in a single storm. Without gutters, that volume erodes stucco, undermines foundations, and rots fascia.
I calculate tributary area per downspout and compare to the SMACNA sizing tables. Most NM homes I inspect have undersized downspouts — 2×3 where they should be 3×4 — causing overflow at every corner during monsoon.
Absolutely. Backed-up gutters ice-dam in winter, rot fascia, and push water back under the drip edge into the deck. Poor grading holds water at the foundation and against siding. Roof problems and drainage problems compound.

I've watched too many neighbors sign contracts they didn't understand for roofs they didn't need. That stops with a written report they own.
