Patriot Roof Guide
Comparing Proposals for a New Shingle Roof
When you collect more than one proposal for a new roof, the totals are easy to compare and the contents are not. Two documents can describe very different roofs in similar words. Reading them side by side, line by line, shows you what you are actually being offered.
Does it name every layer?
A complete proposal should mention the deck, the underlayment, any leak barrier and where it goes, the drip edge, flashing, starter strip, shingles, ridge cap and ventilation. If one of these is missing, ask whether it is included or simply left out of the paperwork.
What happens if the deck is damaged?
No one can see the deck until the old roof is off. A clear proposal explains how damaged wood will be handled, how you will be told and how it will be priced. Vague wording here is one of the most common sources of surprise later.
Which shingle, and which color?
Look for the manufacturer and product line in writing, not just "architectural shingles." If you have chosen a color, make sure it is written down too.
Flashing: new or reused?
Ask whether flashing at walls, chimneys and skylights will be replaced or reused. Either can be reasonable in a given case, but you should know which one you are getting.
Attic airflow
A proposal should say whether ventilation will be changed, added or left as it is, and why. Adding a ridge vent without enough intake air can work against you.
Cleanup, permits and schedule
Check who pulls the permit, if one is needed, how debris will be removed and how weather delays are communicated.
Ask questions in writing
If something is unclear, ask for the answer in writing and keep it with the proposal. Our own proposals follow the order of the Patriot Standard, so you can check each layer against this list. For more on reading any contractor scope, the main Patriot site has a guide to reading a roof replacement scope.
