You may have shingle, tile or slate keeping your home safe from the elements, but without roof underlayment you might as well leave your roof completely uncovered. http://vhbroofing.com/

1. BASIC THINGS YOU NEED TO KNOW
ABOUT ROOF UNDERLAYMENT
VHBROOFING.COM

2. YOU MAY HAVE SHINGLE, TILE OR
SLATE KEEPING YOUR HOME SAFE
FROM THE ELEMENTS, BUT
WITHOUT ROOF UNDERLAYMENT
YOU MIGHT AS WELL LEAVE YOUR
ROOF COMPLETELY UNCOVERED.

3. ROOF UNDERLAYMENT SERVES AS A
BARRIER THAT KEEPS YOUR HOME
WATERTIGHT ALL YEAR ROUND,
PROTECTED FROM HEAVY RAINFALL
AND STRONG STORMS.

4. IT IS CONSTRUCTED BETWEEN YOUR
ROOF DECKING (BOTTOM) AND
TILES OR SHINGLES (TOP).

5. IT PROTECTS YOUR HOME FROM
ANY WATER OR MOISTURE THAT
GETS PAST YOUR TILES OR
SHINGLES.

6. IT PREVENTS MOISTURE BUILD UP
BETWEEN YOUR ATTIC AND THE
ROOFING MATERIAL THAT COULD
CAUSE SIGNIFICANT WATER
DAMAGE TO YOUR ROOF DECKING.

7. IT ALSO PROVIDES A PROTECTIVE
MEMBRANE BETWEEN THE SAP
FROM THE WOOD IN YOUR
DECKING AND THE SHINGLE
RESTING ABOVE IT.

8. THIS SAP CAN CAUSE STRUCTURAL
ISSUES IF YOU DON'T PREVENT IT
FROM MAKING CONTACT WITH
YOUR TILES OR SHINGLES IN THE
FIRST PLACE.

9. AVOID USING:
* REGULAR, PAPER-BACKED
ASPHALT UNDERLAYMENT
* ANY TYPE OF NON-BREATHABLE
FELT/UNDERLAYMENT

10. THE LEVEL OF DIFFICULTY WHEN
INSTALLING IT DEPENDS ENTIRELY
ON THE TYPE YOU'RE USING.
15-POUND OR 30-POUND
ASPHALT/TAR PAPER FELT CAN BE A
TRICKY INSTALLATION EVEN FOR AN
EXPERIENCED ROOFER.

11. WORKING WITH SYNTHETIC
UNDERLAYMENT IS FAR MORE
STRAIGHTFORWARD, BUT THERE'S
STILL THE POTENTIAL FOR MAKING
EXPENSIVE MISTAKES.

12. GENERALLY SPEAKING, IT IS BEST TO
LEAVE THIS JOB TO AN
EXPERIENCED ROOFING
CONTRACTOR.
