TITANIUM vs. Felt Cost Calculator Felt papers tear easily vs. TITANIUM's high strength coated woven construction Felts have no slip resistant features vs. TITANIUM's SURE-FOOT™ & SURE-GRIP™ surface Felt becomes brittle within days of UV exposure vs. TITANIUM's 6 month UV exposure rating Felt leeches oil in the heat and cracks in the cold vs. TITANIUM UDL's -70 °F - 212 °F flexibility Felt papers are susceptible to mold growth vs. TITANIUM's inert synthetic polymers Felt paper is prone to "blow-offs" in windy conditions vs. TITANIUM's high strength anchoring Felts are not covered by warranties vs. TITANIUM's 25, 30 & 50 year warranties Felt comes in 36" wide rolls vs. TITANIUM's 48" wide rolls (faster installs, fewer laps) Felt comes in 2 or 4 square rolls vs. TITANIUM's 10 square rolls A 5000 square foot job requires 25 rolls of #30 felt vs. 5 rolls of TITANIUM Felt paper is not recyclable vs. TITANIUM UDL's 100% recyclability (where facilities exist) Use the Calculator below to work out the cost in dollars of using traditional #15 or #30 felt compared to using our TITANIUM UDL-25 PLUS or TITANIUM UDL-30.

** The installation times are approximations only, the actual time required to install felt or TITANIUM underlayment will vary depending on many factors that can not be addressed with the TITANIUM vs. Felt calculator. The times presented are approximated based on the additional time required to install felt underlayments. For instance, a 5000 square foot job requires 25 rolls of #30 felt compared to only 5 rolls of TITANIUM™, that means extra time and labor to transport and carry the rolls onto the roof deck. The approximations also take into account the additional laps required to complete a job using felt paper, for instance, a rectangular roof deck that is 22 feet in height requires 8 laps (with a 3" overlap) of 36" wide felt paper whereas the same 22 feet can be covered with just 6 laps of 48" wide TITANIUM™. As felt paper requires more laps to complete, it also requires more anchoring devices which adds time and additional costs.

* InterWrap Inc can not be held responsible for any inaccuracies or discrepancies that result from the use of the calculations derived from the TITANIUM vs. Felt calculator. All costs are approximations only. The figures presented here are by no means meant to reflect actual amounts either a roofer or homeowner should expect to pay for labor or materials. The cost per roll of both TITANIUM and felt paper are approximations only and can vary from region to region. Only your roofing contractor can provide you with an accurate quote or final dollar amount for having either felt paper or TITANIUM synthetic underlayment applied to a roof deck. The actual cost of felt paper or TITANIUM is dependent on many factors that can not be accounted for using this calculator. Use of the TITANIUM vs. Felt Calculator is only intended to aid in the decision to use TITANIUM over felt paper. It is in no way meant to be used as a tool for accurately costing roofing projects.
