How to compare roofing estimates.
The bottom line isn’t the whole story.

1. Are they doing the same job?

Start with what's being fixed. Is one quote a repair and the other a full replacement? If someone says you need a new roof, ask them to show you why, with photos. If a repair will do, you shouldn't be paying for a roof.

2. Tear-off or roof over?

A tear-off removes the old roof so the deck can be checked and repaired. Going over the old roof can look cheaper but hides what's underneath. Make sure both quotes say the same thing.

3. What happens if the deck is rotted?

Nobody can see the whole deck until the old roof is off. A good estimate says how rotted wood will be handled and what it costs per sheet, so there are no surprises. We photograph anything we find and get your OK before doing extra work.

4. What goes under the shingles

• Underlayment over the whole deck.
• Ice and water protection at the eaves and in valleys.
• New drip edge at the edges.
• New flashing at walls, chimneys and skylights, not reused old metal.
• New pipe boots.
• Ventilation that lets the attic breathe.

If one estimate lists these and the other doesn't, they're not the same roof.

5. Warranty, in writing

There are two kinds. The manufacturer covers the materials. The contractor covers the workmanship, meaning how it was installed. Ask how long the workmanship warranty is and get it in writing.

6. How they treat you

Watch out for quotes that expire in a day or two, or a big discount if you sign tonight. That's pressure, not a good deal. Our quotes don't expire to rush you, and you get photo proof of every problem we saw.

Also check that the contractor is registered. In Pennsylvania, home improvement contractors need a PA HIC number, and it should be on the estimate. Ours is PA217726.
