Roof Repair & Replacement in McAllen, TX & the Rio Grande Valley
McAllen sits at the center of the Rio Grande Valley, where extreme sun cycles, rapid
temperature swings, and inland wind corridors create one of the most punishing roofing
environments in Texas. SJ&H Roofing designs repair and replacement work for this
specific climate — thermal expansion, overnight contraction, humidity loading, and
inland wind bursts that flex weakened shingles until failure points finally show up.
Roofing in McAllen & the Rio Grande Valley Climate
In the RGV, roofs don’t fail randomly — they fail because the environment forces materials
to move every single day. Shingles expand in blistering afternoon heat and contract hard
overnight. Decking dries out quickly under high sun load. Underlayment stiffens during heat
spikes and fasteners loosen as the deck breathes. Gulf-fed humidity pushes moisture into
micro-gaps while inland wind corridors flex already stressed shingles until they crack,
crease, or lift.

to “missing shingles today.”

Popular Services in McAllen & the Rio Grande Valley
Roof Repair
Thermal cracking, lifted shingles after hard inland gusts, nail pops from deck
movement, and leaks that only show up in certain temperatures — we trace how the
RGV climate is stressing your roof and repair the actual failure point, not just
the stain on the ceiling.
Roof Replacement
When daily expansion and contraction have finally spent the system, we document
why — deck condition, underlayment fatigue, ventilation pathways, and wind-field
exposure — then rebuild with materials and fastening patterns that match RGV heat
and wind behavior.
Storm Damage Inspections
Inland storms hit differently than coastal storms. We map directional wind loading,
creased or snapped shingles, impact points, and moisture-entry paths so you have
labeled photo evidence for both repairs and insurance conversations.
Metal Roofing
RGV sun and heat punish seams, fasteners, and penetrations. We install and repair
metal systems with the right clip spacing, movement tolerance, and flashing
strategy so the roof can expand and contract without tearing itself apart.
Commercial Roofing
Flat and low-slope roofs across McAllen, Mission, Pharr, and Edinburg face ponding,
seam separation, and heat-loaded membranes. We isolate the failure zone and repair
or replace the system with RGV conditions in mind.
Residential Roofing
From heat-stressed shingle roofs in McAllen to full replacements in Weslaco or
Donna, we help you choose the right system for your house, budget, and RGV wind
exposure — not just what’s easiest for the contractor.

The SJ&H Process
- Inspection first: we locate the failure point, not just the symptom.
- Photo documentation: labeled photos + clear notes so you can actually understand what’s happening.
- Recommendation: repair when it’s repair; replace only when the system is truly spent.
- Work performed correctly: flashing, sealing, ventilation logic, and wind/heat detailing done right.
- Final check: we confirm the fix, walk you through what was done, and document the result.

You’ll always know scope, cost, and timeline before work begins. We provide clear
roof-cost breakdowns and flexible financing options — including 0% programs.
Why Homeowners Choose SJ&H Roofing
SJ&H Roofing exists for one reason: roofs in Mississippi, the Coastal Bend, and the Rio
Grande Valley don’t behave like roofs in mild inland climates. Gulf-driven wind,
storm tracks, extreme heat, and humidity create uplift pressure, fatigue materials,
and push water through micro-gaps and underlayment laps before it ever shows up inside.
That’s why we’re inspection-first in every market we serve. We diagnose, document, and
explain before we recommend anything — so you don’t get shoved into a replacement when
a repair would have solved it.
We locate the true failure point, not the first visible symptom — and we prove it with photos & notes.
Uplift zones, pressure shifts, moisture migration, flashing transitions — we fix the actual mechanics,
not just the cosmetic symptoms.
Most leaks are repairable early. Catch it now, fix it correctly, and avoid “storm-compounded” failures
that force full replacement.
Timestamped photos + clear reporting give you evidence — not guesswork — for both repairs & insurance.
FAQs
Do you repair roofs or only replace them?
We repair whenever it’s repair. If replacement is truly the smarter move, we document why — so you’re
deciding based on evidence, not pressure.
Can you help after storms?
Yes — we inspect uplift zones, missing or creased shingles, seal failures, and moisture entry paths,
then provide photo documentation and the correct fix plan.
