Title: Roof Installation: Key Questions to Ask Before You Hire a Roofer
Introduction
A successful roof installation starts long before crew arrives—it begins when you choose the right contractor. Asking the right questions helps you avoid surprises, ensures clarity, and sets expectations. In this post, we’ll cover what you should ask, what red flags to watch for, and how this ties back to the step-by-step installation guide we shared earlier.
Let’s dive into the questions you should have on your vetting list. (Don’t forget to read the companion post, “The Complete Step-by-Step Roof Installation Guide”, to fully understand how each phase works.)
Why Asking Questions Matters
Hiring a roofer without proper vetting can lead to:
- Hidden costs
- Delays or inconsistent scheduling
- Poor workmanship
- Lack of accountability
- Unexpected structural issues
Your questions help filter out unreliable providers and find someone with the expertise to execute your roof installation with confidence.
Essential Questions to Ask a Roofing Contractor
Below is a list of key questions you should ask any roofing contractor before hiring them for installation:
1. What’s Your Experience With Roof Installations?
You want someone who’s done your type of roof—shingle, metal, flat, etc. Ask for past project photos and references.
2. What Materials & Brands Do You Use?
Materials matter. Ask what shingle brand, underlayment, flashing materials, and ventilation products they use—and why.
3. Can You Walk Me Through the Installation Process?
A trustworthy roofer will outline tear-off, deck repair, underlayment, flashing, shingle installation, and inspection steps.
4. How Will You Handle Inspections & Permits?
Your roofer should be familiar with local building codes and handle permit applications. Ask whether inspections are included in their schedule.
5. What’s the Project Timeline?
Get a realistic schedule: start date, expected major milestones, contingency days for weather, and completion date.
6. How Do You Protect Surrounding Property?
Ask about daily cleanup, tarps, gutter protection, and measures to prevent damage to landscaping or property.
7. What Happens If You Encounter Unforeseen Damage?
What if the roofer finds rot or structural damage during tear-off? Ask how they address this and how it impacts cost and timing.
8. How Do You Guarantee Quality Workmanship?
Without diving into “guarantees” per se, ask how they inspect their own work, what quality checks they follow, and how they address deficiencies.
9. What’s the Payment Schedule?
Clarify deposit, progress payments, and final payment. Watch out for overly large upfront demands.
10. Can You Provide a Written Scope & Contract?
The contract should detail which materials, labor, timeline, and cleanup responsibilities are included.
Red Flags to Watch Out For
Here are warning signs when talking with potential roofers:
- No willingness to explain their process
- Vague or overly generic answers
- High-pressure tactics or demand for full payment up front
- No portfolio or references
- Hesitation about handling inspections or permits
- No clear plan for debris cleanup
If a contractor can’t answer your questions thoroughly, that’s a cue to move on.
How These Questions Tie Into the Installation Process
Every question above maps to a phase of the roof installation process:
- Experience, materials, process → ensures proficiency in each step (tear-off, underlayment, flashing, etc.)
- Inspections & permits → avoids violations or redo work
- Timeline & protection → keeps your project on track and safe
- Unforeseen damage response → prepares you for surprises under the deck
- Quality checks, payment schedule, contract → aligns expectations, accountability, and project scope
Before the crew shows up, you want clarity. After reading the roof installation guide in our first blog, you’ll better understand how each question reveals integrity and competence.
Example Dialogue with a Roofing Contractor
Here’s a mock conversation to illustrate how to engage:
You: “Can you walk me through your roof installation stages—especially how you handle flashing and ventilation?”
Contractor: “Sure. First we tear off existing roof, then inspect and reinforce decking. Then install underlayment, ice barrier, flashing around chimneys, and ridge vents. We finalize with shingles and inspection. We’ll also haul off debris every day.”
In this exchange, you’re testing their process knowledge and attention to detail.
Moving Forward: Taking the Next Step
Once you’ve asked qualified contractors your questions, compare:
- Responsiveness
- Clarity of answers
- Professionalism
- Cost estimates and transparency
