Roof Replacement FAQ
How Long Will Your New Asphalt Shingle Roof Last?
You’ll often see 20–25 years from a quality architectural shingle roof when your attic ventilation is doing its job. If your attic runs hot, your shingles can age faster. It’s not fair, but it’s true.
How Do You Know You Need Roof Replacement, Not Another Repair?
If you keep paying for repairs, keep seeing new issues, or your shingles feel brittle and tired, you’re usually past the point where repairs make financial sense. You’re not “saving money” if you’re buying the same fix three times.
Can You Install New Shingles Over the Existing Roof?
Sometimes local code allows it, but you typically get a better result with a tear-off. You avoid trapping problems underneath, you can inspect decking properly, and you don’t stack extra weight on the structure.
What Happens If You Find Bad Decking During Tear-Off?
You pause, you document it with photos, and you review your options before you move forward. Decking damage isn’t rare, especially if the roof leaked for a while or the attic stayed damp. If it’s part of a storm damage claim, you contact the adjuster and get approval before proceeding.
Should You Call Us Before You File a Storm Damage Claim?
Yes. You’ll get better documentation, clearer photos, and someone who can point out damage adjusters often miss (valleys, flashing, secondary slopes). If the initial estimate comes in light, you’ll also get help requesting a reinspection or filing a supplement.
How Long Does Roof Replacement Take?
Most homes take 1–3 days, depending on roof size, pitch, complexity, and weather. You’ll get a realistic schedule up front, and you’ll hear from your project lead if weather forces a change.
How Loud Is It?
Pretty loud, especially during tear-off. If you work from home, plan for a noisy day one. If you’ve got pets, keep them inside and away from the action.
Where Does the Dumpster Go?
You’ll usually place it in the driveway or another accessible spot. If you have a narrow driveway, steep grade, or HOA restrictions, bring it up early so you don’t scramble later.
Do You Need to Be Home During Installation?
Not necessarily. You just need to stay reachable by phone, and you’ll want pets safely inside because the noise and foot traffic can stress them out. We protect landscaping and work areas as part of the setup.
What Should You Do After a Storm?
If you suspect damage, don’t climb up there. You can walk the perimeter, look for missing shingles or debris, check ceilings for new stains, and call for an inspection. Simple and safe.
What If It Rains During Your Roof Installation?
You don’t start a roof when rain is likely, and you use underlayment and temporary protection if weather shifts unexpectedly. The goal is simple: keep your home dry, period.
Why Shouldn’t You Just Go With the Lowest Bid?
Cheap bids usually cut corners on underlayment, flashing, ventilation, or crew insurance. You might save $2,000 upfront, but premature failure or hidden liability can cost you $10,000+ down the road. Get at least three estimates and ask specific questions about materials and methods.
