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.
1. What is this building’s mission statement?
Before calls are made to Detroit Roofing Service, the first item to address is the company’s mission statement as it relates to the building.
You need to know as much about the building and its future as possible.
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.
2. 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, 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.
3. Što su dostupni fleksibilna membrana krovne opcije?
Termoplastični membrane se temelje na plastičnim polimerima.
Kao i druge termoplastike, Hypalon materijali su zatvorene primjenom topline po šavovima.
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.
4. 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.
A steel or wood deck that easily accepts fasteners makes a good substrate for a mechanically fastened membrane.
For those concerned with building aesthetics, colored membranes can make an attractive contribution to the building’s appearance.
5. 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. You want the membrane tested with the insulation that you are using on your building.
6. 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.
7. 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.
Facility executives must assure that all relevant considerations, including weight, are taken into account in the decision-making process.
8. 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.
Ask the contractor if his or her company is a member of a local, state, regional or national industry association. Izvođači koji su uključeni u profesionalnim udrugama općenito su bolje informirani o najnovijim zbivanjima i problemima njihove industrije.
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.
Nacionalna Krovovi Izvođači udruga nudi profesionalne selekcije krovište vodič. U Dodatku, mnogi proizvođači su odobreni izvođača programa s posebnim kvalifikacijama koji sugestije mora dovršiti prije odobrenja.
9. 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, 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.
Most professional roofing contractors will offer periodic maintenance inspections throughout the year. These inspections help ensure your project complies with the standards specified in the warranty.
10. After the roof is installed, što nakon servis i obrazovni programi su dostupni za upravljanje objektima tima?
Specific courses are available to help building owners and facilities managers learn more about various roofing systems, materijali i komponente; izolacija i pribor proizvoda; elementi krovne dizajna; izbor izvođača radova; Jamstva i razmatranja održavanje.
