When it comes time to replace your roof, there are dozens of options at your disposal. Generally, there are two ways to go about replacing a roof: either the old roof is torn out down to the deck or the new system is placed over the existing one. There are some benefits to each method. Tearing off the old one includes: finding defects in the old system as it’s dismantled; if condensation has built up, proper attic ventilation can be installed to keep out moisture; waterproof shingle underlays can be installed to prevent future leaks caused by ice and wind-driven rain. The A&Z professionals will advise you on which method is best for your building or residence. Contact A&Z today for your free consultation.
