Common Questions About Exterior Work
Orientation — what this is
Homeowners frequently ask similar questions when they’re thinking about roofing, siding, windows, or gutters. Some questions are about the work itself; others are about how to pick a contractor or what to expect from the process. This page walks through the ones we hear most often. If a question here doesn’t match your specific situation, reach out—these are patterns, and your project may have details that shift the answer.The key figures
Roofing: Material costs account for about 40% of the total; labor and overhead the other 60%. A thorough proposal spells out the scope, materials, and workmanship guarantee. Rushing this decision typically costs more later. Siding, windows, gutters: The same principle applies—quality materials matter, but installation quality determines whether they last. Exterior work is a decades-long decision, not a one-year expense.Next step
How do I know if a roofing quote is actually thorough?
I compare it against what the National Roofing Contractors Association flags as the sign of a serious proposal — materials, scope, and workmanship spelled out, not just a number. A one-page estimate that lists only the total price is a red flag. A good proposal covers materials by type and quantity, the scope of the work, what’s included and what’s not, and the warranty on labor and materials.
What should I actually check before signing with any contractor?
The City of Boston’s consumer affairs office lays out the contract terms and red flags worth checking first, and it’s a good five-minute read before any exterior project starts. At minimum: verify they’re licensed, check the contract includes start and end dates, make sure the payment schedule doesn’t require payment before work is done, and confirm the warranty terms are in writing.
What’s the difference between a repair and a replacement?
A repair addresses specific damage or wear in one area; a replacement addresses the entire system. For roofing, the question often becomes: is the roof failing in one spot, or failing across the board? A contractor should be able to tell you whether your roof has five good years left or is near the end of its lifespan. Don’t pay to repair what should be replaced, and don’t replace what can still perform.
Should I get multiple quotes?
Yes. Three quotes from licensed contractors who are willing to walk you through their proposal is a reasonable minimum. You’re not just comparing numbers; you’re comparing how clearly they explain the work, how they answer your questions, and whether you’d trust them on your house. The lowest quote isn’t always the best deal—it might mean they’re cutting corners or underpriced and won’t finish the job properly.
What happens if I go with the wrong contractor?
Poor exterior work can lead to water damage, structural problems, and expensive repairs years later. That’s why vetting the contractor matters more than saving a few hundred dollars on the initial price. If work goes wrong, your recourse depends on whether you have a written contract, proof of payment, and documentation of what was promised versus what was done.
How long does exterior work typically take?
Roofing a typical home takes three to five days if weather cooperates and the contractor isn’t dealing with hidden damage underneath. Siding, window replacement, and gutter work vary widely based on the scope. The timeline should be clear in your contract, not as a range but as a specific duration. Be wary of contractors who give vague timeframes or constantly extend the schedule—delays cost money and expose your house to weather.
When should I ask about warranty?
Ask for warranty details upfront, before you sign anything. Warranties cover two things: materials (from the manufacturer) and labor (from the contractor). A good contractor stands behind their work for at least a year, and the warranty should be in writing. If something fails early, you need to know who to call and what’s covered—the contractor’s promise or the product’s guarantee.
