From the owner

Why I wrote this guide.

Most people replace one roof in their life. The contractor across the table has done four hundred. This guide closes that gap before you sign anything: what a low quote leaves out, what gets found once the old shingles come off, and the questions a good roofer will be glad you asked.

What is inside

Twelve chapters, written from our own jobs in Moncton, Riverview and Dieppe. Read the two that apply to you and ignore the rest.

Chapter06

Where the hidden costs actually live

And which ones only show up after the tear-off starts.

What a complete quote includes

Line by line, so you can hold two quotes side by side and compare the same things.

Chapter04

The questions to ask before you sign

And what a straight answer to each one sounds like.

Why most roofs fail at the install, not the shingle

The same shingle lasts thirty years on one house and eight on the next. The difference is the crew.

30 day price lock

The price we give you is the price.

When we measure your roof, you get one number. That number is locked for 30 days, so nothing moves while you think it over, get a second opinion, or talk it through at home.

If we open the roof and find something underneath that changes the work, we stop and show you before we touch it. You decide. Nothing gets added to your bill that you did not agree to first.
