The cikakken yin rufi bayani daya gini iya zama mafi munin zaɓi don wani m saukar da titi. Wannan ke nan, domin ba biyu gine-gine ne daidai m, har idan sun hankali kama da juna. To yaya ka zabi wani sabon rufin, ba dukan zabi a kasuwa? Za ka iya fara da tambayar jerin tambayoyi, kafin ka zabi rufin, da yin rufi kwangila ko manufacturer.
1. Mene ne wannan gini manufa bayani?
Kafin kira aka Detroit yin rufi 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, watakila kana buqatar wani asali rufin.
Misali, kamar yadda mafi kamfanonin motsa zuwa ga aiki 24 hours kullum, kwana bakwai a mako don gamsar duniya abokan ciniki, da bayanai cibiyar dole ba Spring a saman rufin gidajen zuba. Water a kwamfuta tsarin kullum lokatai bala'i.

Shin wani bangare na jimlar makamashi shirin? Akwai girma damuwa game da birane zafi tsibiran. nunawa, farin rufi sun zama ban sha'awa a cikin wadanda wuraren da 'yan dalilai. Suka ci gaba da ginin mai sanyaya, rage kwandishan halin kaka da kuma rage zafin rana-loading na kewaye yanayi.
2. Abin da jiki da kuma sauran abubuwa da tasiri da yin rufi tsarin selection?
Bayan gano a raga, kuma manufa mai makaman, yana da lokaci zuwa kimanta ginin kanta.
Idan ya zo ga rufin sauyawa, kana bukatar ka jerin halayen rufin yankin kanta. Yana da kyau a daki-daki, rufin ta size, siffar, gangara, 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.
3. What flexible-membrane roofing options are available?
Thermoplastic membranes are based on plastic polymers.
Like other thermoplastics, Hypalon materials are heat sealed at the seams.
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. Does all roofing material delivered to the job site bear the UL label?
If not, specify that it must. 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.
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.
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. Contractors involved in professional associations generally are better informed on the latest developments and issues of their industry.
The installation of different roofing systems varies considerably. Ilimi da horo ne mafi muhimmanci abubuwa a cikin shigarwa na yin rufi tsarin. Tabbatar da yin rufi dan kwangila da ka za i ya yi cikakken da gudana horo a kan tsarin da ake shigar.

9. Abin da ake bashi garanti, kuma da wanda?
Akwai biyu na asali Categories yin rufi garanti. 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. Misali, 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, abin da bayan sabis da kuma ilimi shirye-shirye suna samuwa ga wurare management tawagar?
Specific Darussan suna samuwa don taimakawa ginin owners da kuma wurare manajoji ƙarin koyo game da daban-daban yin rufi tsarin, kayan da aka gyara; rufi da kuma m kayayyakin; abubuwa na rufin zane; kwangila selection; garanti da kuma goyon baya sharudda.
