          Q:My local store is out of the Liberty Base and won't have any for some time. I have to do my low slope patio roof next week and want to use the Liberty cap sheet. I'm not concerned about warranty coverage, the patio will be rebuilt in 3 years.

          A:  I used this on a small shed 16 x 8. The roof was leaking and had shingles already installed. I put this over the existing shingles 2 years ago and have not had any leaks since.

            A:  Hello, the Liberty Cap product doesn't necessarily require the base sheet. An asphalt primer meeting ASTM D41 would be applied on the plywood deck and then covered over with Liberty Cap. This provides a 10 year limited warranty against manufacturing defects. If the Liberty Base product is used as part of your installation, it would provide 15 years of limited warranty. Please give our technical team a call at 877-GAF-ROOF to discuss your installation in detail. Thank you for your question.

                A:  Weatherwatch is a great product.  Have used on bay window roofs and on shallow pitched roofs. Stopped all leaks; prevented leaks during massive rainfall associated w hurricanes.

                  Q:Is this the first underlayment for the bottom edge of a roof, instead of Ice and Water barrier? Would using this on the bottom edge of a roof and then using the GAF FeltBuster on top of it be sufficient without needing additional underlayments?

                  A:  Use as the first underlayment at the edge of the roof but Use only in 3ft to 4ft length it is one of the best products out there i would recommend

                  by|Apr 6, 2022

                    A:  Hello, this product is used at the eave edge and should be installed at least 24" above the warm wall. It's also installed at the other vulnerable areas of the roof at areas such as valleys, around penetrations and at wall to roof junctions. FeltBuster would be installed on the remaining areas of the roof. Thank you for your question
