Choosing the correct replacement for an aged roof – or identifying the best choice for a new building – is no easy task. The perfect roofing solution for one building may be the worst option for another just down the street. That’s because no two buildings are precisely alike, even if they closely resemble each other. So how do you choose a new roof, given all the choices in the marketplace? You can start by asking a series of questions, before you choose the roof, the roofing contractor or the manufacturer. What is this building’s mission statement? Before calls are made to Southfield MI Roofing Service, the first item to address is the company’s mission statement as it relates to the building. More often than not, the building itself dictates the appropriate roofing system specification. Does the roofing company plan to keep this building as part of its real estate assets for the next 10 to 20 years? Are there any plans to expand it in the near future, or to change its use? What are its current and future occupancy, insulation requirements, aesthetic priorities and even the maintenance schedules for rooftop equipment? If it’s a spec building, maybe you only need a basic roof. For example, as more companies move toward operating 24 hours daily, seven days a week to satisfy global customers, the data center must never spring a rooftop leak. Water on computer systems generally spells disaster. A special set of concerns arise for cooling-dominated climates. Does the roof contribute to air conditioning savings and address other key issues? Is it part of a total energy program? There is a growing concern about urban heat islands. Reflective, white roofs have become of interest in those areas for a few reasons. They keep the building cooler, reduce air conditioning costs and also minimize the heat-loading of the surrounding environment. What physical and other elements influence the roofing system selection? After identifying the goals and mission of a facility, it’s time to evaluate the building itself. When it comes to roof replacement, you need to list the attributes of the roof area itself. It’s best to detail the roof’s size, shape, slope, deck construction, edge detailing, protrusions, rooftop access and existing roofing system. Along with this basic information, you need to find out why the original roof is no longer adequate. What flexible-membrane roofing options are available? Thermoplastic membranes are based on plastic polymers. Hypalon thermoplastic begins as a thermoplastic, but cures over time to become a thermoset. Modified bitumen membranes incorporate the formulation and prefabrication advantages of flexible-membrane roofing with some of the traditional installation techniques used in built-up roofing. Modified bitumen sheets are factory-fabricated, composed of asphalt which is modified with a rubber or plastic polymer for increased flexibility, and combined with a reinforcement for added strength and stability. Which type of membrane and attachment system are best for the building? Many factors determine the best system for a particular building. For most buildings, there are a number of options and advantages that need to be weighed against the facility’s mission statement. The decision should not be made only on the basis of cost. Other important considerations for membranes are building height, wind exposure, anticipated roof traffic and aesthetics. The attachment system also depends on the specific building’s characteristics. For those concerned with building aesthetics, colored membranes can make an attractive contribution to the building’s appearance. Does all roofing material delivered to the job site bear the UL label? Additionally, be sure that the roof assembly you buy or specify, which includes the insulation, is UL-classified and -labeled. Make sure that the product you are getting is the actual product that was tested. You don’t want something that is similar but not equal. Look for the label at the job site and make sure all components of the system were tested together. You want the membrane tested with the insulation that you are using on your building. Does the system require a wind uplift rating? Wind uplift damage can be extensive and expensive. Accepted as an industry standard, American Society of Civil Engineers Standard 7-95, “Minimum Design Loads for Buildings and Other Structures,” can be used to determine the wind zone of the building. Wind uplift testing, such as that performed at Factory Mutual or Underwriters Laboratories, can be used to determine that the selected roof system meets or exceeds the local wind uplift requirements. How much does the completed system add to the dead load weight of the roof structure? In choosing any reroofing option, the facility executive should be aware of the load-bearing capacity of the roof deck to make sure the right flexible-membrane option is chosen. In new construction, savings in structural steel can often be achieved by installing one of the lighter flexible-membrane systems. A lighter system often allows you to reroof directly over your existing roof, while the heavier ones may require you to tear off the old roof and begin anew. What are the expertise and financial strengths of the roofing contractor you are considering? Roofing contractors need to be chosen with great care. The introduction of new roofing materials and application techniques within the past 10 years has led to many changes. A professional roofing contractor should be familiar with different types of roofing systems, to help you make the best decision for your facility, based on your budget. Also check your state’s licensing requirements and find out if the contractor is bonded by a surety company. The installation of different roofing systems varies considerably. Education and training are the most important elements in the installation of roofing systems. Make sure the roofing contractor you choose has had detailed and ongoing training on the system being installed. Also, make sure the contractor is approved by the manufacturer to install that specific system. What is warranted and by whom? There are two basic categories of roofing warranties. The contractor’s warranty typically covers workmanship. The manufacturer’s warranty covers at least the materials, though many cover additional items. Even if the manufacturer’s warranty is broad, it will not completely protect you if the roof is improperly installed. Carefully read and understand any roofing warranty offered and watch for provisions that would void it. For example, it’s nearly impossible to avoid all ponded water. Ponded water can be caused by a clogged roof drain or deflection of the roof deck in between the support columns. Proper roof maintenance can help assure that the warranty remains valid. Be aware of warranty language that voids the guarantee. More important than the warranty, however, is getting the right flexible-membrane roof on your building in the first place. After the roof is installed, what after service and educational programs are available for the facilities management team? Specific courses are available to help building owners and facilities managers learn more about various roofing systems, materials and components; insulation and accessory products; elements of roof design; contractor selection; warranties and maintenance considerations.

Odabir ispravne zamjena za ostarjelog krov – ili identificiranje najbolji izbor za novu zgradu – nije jednostavan zadatak. Savršeno krovište rješenje za jednu zgradu može biti najgora opcija za još samo niz ulicu. To je zato što ne postoje dvije zgrade su upravo na isti način, čak i ako oni nalikuju jedni drugima. Pa kako se izabrati novi krov, s obzirom na sve opcije na tržištu? Možete početi pitati niz pitanja, Prije nego se odlučite na krov, krovni ugovor ili proizvođač. Što je misija ove zgrade? Prije nego što su pozivi napravio to Detroit Krovovi usluga, prva stavka na adresu je misija tvrtke kao što se odnosi na zgradu. Morate znati što više o zgradi i svoju budućnost što je više moguće. Da li krovne tvrtke planiraju zadržati ovu zgradu kao dio svojih nekretnina sredstava za sljedeći 10 do 20 godina? Postoje li planovi da se ona proširi u bliskoj budućnosti, ili mijenjati njegovo korištenje? Koje su njegove sadašnje i buduće popunjenosti, zahtjevi za izolaciju, estetski prioriteti, pa čak i raspored održavanja opreme na krovu? Počnite svoja pitanja s tim što se zgrada će se koristiti za. Na primjer, što više tvrtki kretati prema operativnim 24 sata dnevno, sedam dana u tjednu kako bi zadovoljio globalne klijente, podatkovni centar nikada ne smije proljeće curenja na krovu. Voda na računalnim sustavima općenito uroka katastrofa. Poseban niz zabrinutosti nastati za klime hlađenje dominiraju. Da li je krov doprinijeti klimatizacije štednje i rješavanje ostalih ključnih pitanja? Je li to dio ukupnog energetskog programa? Postoji rastuća zabrinutost zbog urbanih toplinskih otoka. zamišljen, Bijeli krovovi su postali od interesa u tim područjima za nekoliko razloga. Oni drže hladnjak zgrade, smanjiti troškove klimatizacije i smanjili toplinski učitavanje okruženja. Ono fizičko i drugi elementi utječu na izbor krovnog sustava? You need to examine building codes, weather trends, topography – even the direction the building faces. Kada je u pitanju krova zamjena, morate navesti atribute samom području krova. To je najbolje da detaljno veličine krovne, oblik, nagib, izgradnja palube, rub pojedinostima, izbočenja, Pristup na krovu i postojećih krovni sustav. Uz ove osnovne informacije, morate saznati zašto je izvorni krov više nije adekvatna. Što su dostupni fleksibilna membrana krovne opcije? The most common is EPDM, often referred to as “rubber roofing.” Hypalon termoplast počinje kao termoplasta, ali lijekove s vremenom postati termo. Modificiranog bitumena membrane sadrže formulacije i montaža prednosti fleksibilnog-membrane krovove s nekim od tradicionalnih tehnika instalacije koji se koriste u izgrađenom krovišta. Modificirani bitumenske ploče su tvornički proizvedeni, sastavljen od asfalta koji je modificiran s gumenim ili plastičnim polimera za povećanje fleksibilnosti, i pomiješa s armaturom za dodatnu snagu i stabilnost. Koju vrstu membrane i sustava za pričvršćivanje su najbolje za zgrade? Mnogi čimbenici određuju najbolji sustav za određenu zgradu. Za većinu zgrada, postoje brojne mogućnosti i prednosti koje treba odvagnuti misije Objekt je. Odluka ne bi trebala biti samo na temelju troškova. Ostali važni razlozi za membrane su zgrade visine, izloženost vjetar, predviđen krov prometa i estetike. Another alternative is the fully adhered system, in which the membrane is attached to the prepared substrate using a specified adhesive. Za one koji se bave građevinskim estetike, boji membrane mogu napraviti atraktivan doprinos izgradnji izgledu. Da li svi krovište materijal dostavljen na gradilištu nose UL oznaku? Ako ne, odrediti da se ona mora. This is the only way you can guarantee that the roofing materials installed on your roof are the same materials tested by Underwriter’s Laboratories. Uvjerite se da je proizvod koji se dobiva je stvarni proizvod koji je testiran. Vi ne želite nešto što je slično, ali nisu jednaki. Potražite oznaku na gradilištu i provjerite jesu li sve komponente sustava su testirane zajedno. Želite membranu testiran s izolacijom koji koristite na svoju zgradu. Da li je potrebna sustav vjetra izdizanja rejting? šteta Vjetar podizanje može biti opsežna i skupa. Prihvaćen kao industrijski standard, Američko društvo građevinskih inženjera Standarda 7-95, “Minimalni projektna opterećenja za zgrade i druge građevine,” mogu se koristiti za određivanje vjetra zonu objekta. Ispitivanje podizanje vjetra, kao što je ona izvedena na Factory Mutual ili Underwriters Laboratories, može se koristiti kako bi se utvrdilo da je odabrani krovni sustav ispunjava ili premašuje lokalne uvjete vjetar poboljšavanje. Koliko je dovršen sustav dodati u masu mrtvog opterećenja krovne konstrukcije? U izboru bilo reroofing opcije, objekt izvršni trebali biti svjesni nosivost krova palube kako bi bili sigurni pravo fleksibilna membrana opcija je izabran. U izgradnju novih, uštede u konstrukcijskog čelika često može se postići ugradnjom jedan od lakših fleksibilne membrane sustava. A ballasted roof may be the best choice for a given facility. Koji su stručnost i financijski prednosti krovište izvođača razmišljate? Krovni radova moraju biti izabran s velikom pažnjom. Uvođenje novih krovnih materijala i tehnike primjene u prošlosti 10 godine dovela je do mnogih promjena. Profesionalni krovne izvođač treba biti upoznat s različitim vrstama krovnih sustava, pomoći da napravite najbolji izbor za Vaš objekt, na temelju proračuna. Insist the contractor supply you with copies of insurance certificates that verify workers’ compensation and general liability coverages. Instalacija različitih krovnih sustava znatno se razlikuje. Obrazovanje i usavršavanje su najvažniji elementi instalacije krovni sustavi. Provjerite je li Krovopokrivač izabrati imao detaljan i trajnu izobrazbu o sustavu koji se instalira. The quality of workmanship is crucial to good roof performance. Što je zajamčen i od koga? Postoje dvije osnovne kategorije krovnih jamstva. Jamstvo izvođača obično pokriva izrade. Jamstvo proizvođača pokriva barem materijale, iako su mnogi pokriti dodatnim stavkama. Čak i ako jamstvo proizvođača je široka, on neće u potpunosti vas zaštititi ako neispravno instalirana na krovu. Pažljivo pročitati i razumjeti bilo krovnog jamstvo ponudio i paziti na odredbe koje bi ga prazninu. Na primjer, to je gotovo nemoguće izbjeći sve činila ribnjak voda. Činila ribnjak voda može biti uzrokovan začepljen krovni odvod ili otklona krovu između potpornih stupova. Pravilno održavanje krova može pomoći osigurati da jamstvo i dalje vrijedi. Budite svjesni jamstva jezika koji poništava jamstvo. Tipičan program za održavanje se sastoji od detaljnog vizualnog pregleda krova sustava, treperi, izolacija i povezane komponente identificirati sve potencijalne problematična područja. Nakon što je instaliran na krovu, što nakon servis i obrazovni programi su dostupni za upravljanje objektima tima? Posebni tečajevi su dostupni kako bi vlasnici zgrada i objekata menadžeri saznati više o raznim krovni sustavi, materijali i komponente; izolacija i pribor proizvoda; elementi krovne dizajna; izbor izvođača radova; Jamstva i razmatranja održavanje.
