Making the Right Call

How to Tell If You Need a Roof Replacement

Our team always inspects your current roof first. We only recommend replacement when it's truly the right move — but here are the signs that time has come.

Signs You Need a Replacement

  • Roof is 20+ years old and showing widespread wear
  • Repairs are happening repeatedly — costs are adding up
  • Poor original installation is causing recurring problems
  • Severe water damage or significant structural leaks
  • Extensive repair costs rival the price of a new roof
  • Granules filling gutters and shingles losing texture

When Repair May Be Enough

  • Roof is relatively new with isolated damage
  • Damage is confined to a small, specific area
  • Underlying structure is sound with no rot or decay
  • Storm damage on an otherwise healthy roof
  • Missing or cracked shingles in a limited section
  • Flashing or vent issues only — no deck damage

4 Key Benefits

Four Fantastic Benefits of a Roof Replacement

1

Gives Your Home a Facelift

A new roof is one of the most visible upgrades you can make. With styles, colors, and materials to suit any taste, MEC Builds transforms your home's curb appeal instantly. Preview your new roof before installation with the Owens Corning® Design EyeQ® tool.

2

Skyrockets Energy Efficiency

Our TruDefinition® Duration® COOL Shingles reflect the sun's rays to reduce heat buildup, cutting cooling costs. Better insulation and ventilation also regulate interior temperatures year-round and prevent moisture damage.

3

Boosts Property Value

Homeowners recoup an average of 56.9% of costs on an asphalt shingle replacement according to the Journal of Light Construction. Better energy efficiency, improved curb appeal, and reduced maintenance all drive resale value up.

4

Saves Money on Repairs

Patching an aging roof over and over adds up fast. A full replacement eliminates that cycle — and our flexible financing options make it fit your budget with manageable monthly payments.

Good to Know

Common Questions About Roof Replacement

How long does a roof replacement take?

Most residential replacements take 1–3 days depending on size, complexity, and conditions. Here's how a typical project unfolds:

Day 1

Old roof removal, deck inspection, repairs if needed, and start of new installation.

Day 2

Complete installation, flashing, ventilation, and ridge caps.

Day 3

Final inspection, magnetic nail sweep, full cleanup, and project walkthrough.

You can stay home throughout — the interior is unaffected. We notify you before any particularly loud work begins.

Customer Reviews

Real Reviews from Real Northern California Homeowners

Couldn't believe MEC could do a tear off and install of our 2,800 sq. ft. house roof in one day. They did — in a most professional manner. Cleaned up so thoroughly you would have thought they were never there. Not the lowest in pricing but the lowest in long-term, overall cost. You get what you pay for.

Heino Nicolai — Nevada County, CA

Impeccable customer service and professionalism on all levels. I sought 3 different bids for reroofing my 4,500 sq. ft. home. MEC fit us into the schedule quickly and my house was reroofed in ONE day. By the time I got home it was completely clean — not a nail on the ground. Absolutely worth it.

Andrea Berry — Northern California

We shopped for reputable roofing companies in Nevada County. MEC Builds stood out because of their reputation of giving back to the community. We could not be happier — our new roof is beautiful. The work product is outstanding, and the roof warranty is great. I do highly recommend MEC Builds.

Albert Portillo — Nevada County, CA

I had a great experience from start to finish. Their customer service really stood out — they were responsive, professional, and took the time to answer all of my questions without rushing me. The team showed up on time, kept everything organized, and made the whole process stress-free.
