The Roof Restoration Diaries



There are various roof systems readily available in today's market, each with different staminas and weaknesses. Listed below I will describe each system briefly, then note the disadvantages and pros.

Thermoplastic and PVC- Single ply, can be mechanically affixed, fully ballasted or adhered.

Pros- Superior efficiency in ponding water situations. Very lightweight roof coverings, in the community of 30lbs. per 100 sq. ft. Comes in white if a cool roof is preferred, or in a number of various colors for aesthetic concerns. An additional plus with these roofs is that large customizeded field sheets can be gotten from the manufacturing facility, minimizing joints secured by the crew on the jobsite. Immune to ozone, algae and area joints are 3-4 times stronger compared to EPDM submitted joints. There is likewise a remarkable quantity of versatility in the material. And since seams can be bonded with warm air, there are no toxic fumes to take care of. Both 15 and 20 year warranties readily available.

Cons- Being single ply, they are at risk to thrown out cigarettes, sharp things dropped on the membrane layer, and busted glass from containers tossed on roof (this happens a LOT) I usually discourage clients from mounting these sorts of systems if the roof has a lot of foot traffic or is quickly available to unapproved personnel. In the past, material shrinking went to times an extreme trouble on Thermoplastic and PVC roofing systems, but modifications in structure and production has actually relieved this issue. These roofing systems still diminish gradually, though not to the factor of failing as in the past.

Profits- Great roofings, specifically on roofs that pond water heavily, as long as the roof is normally easily accessible just to licensed employees.

Asphalt Modified Bitumen- This roof is just what a great deal of individuals call a rubber roof, when it remains in truth composed primarily of asphalt. It is available in 3 ft. broad rolls and is normally torched down with an open flame, though they could be used with hot air welders in particular conditions too.

Pros- In my viewpoint, the greatest stamina of these roofings is exactly how well they take on outside stresses. They handle foot traffic far better compared to other membrane, and are challenging to puncture, specifically if they have a granulated surface. These roofs are so challenging as a matter of fact, that many insurance companies will not even identify hailstorm damage as they do on various other roofs (I have actually directly seen customized roofings absolutely mauled with hail and come out entirely undamaged).

Disadvantages- The most glaring downside with these systems is that there is a joint every three feet, makings for a LOT of seams. You'll possibly be fine with this system if you have an attentive crew with a qualified foreman who will certainly make certain that every seam on the roof is triple inspected. Otherwise, you can be quite sure you will certainly wind up with leakages rather soon, well before the service warranty runs out in my experience. And large ponding areas of water on these systems will break down the product too soon.

Profits- With a good, knowledgeable crew this can be an excellent roof on a structure that does not pond water exceedingly. click here And if you have a structure with a lot of rooftop foot website traffic, this is most likely the only means to go.

Foam roofing systems- This system is used with a huge spray unit, spraying 2 liquid components (isocyanate and resin) When the liquids are mixed together, they increase 20-30 times and will certainly comply with concrete, wood, steel and most existing roof systems, but according to the suppliers, NOT to changed asphalt.

Pros- When complete, the roof is monolithic without seams, fully adhered and has protecting residential properties.

Cons- Full disclosure, I have actually restricted experience with these roofings right here in NE Illinois. We don't mount them, however I have actually gotten on 9-10 buildings with this system, and all of them leaked badly, in a number of cases within months of being installed. Leaks are really tough to track down and challenging to fix also when found, as repair work materials don't abide by this surface area effectively.

Bottom line- Based on my undoubtedly limited experience with this system, I would not advise my customers to go this route when a brand-new roof is needed.

EPDM Rubber- Rubber roofing systems could be fully adhered, mechanically secured or weighed with ballast (Riverbed gravel or pavers) They are versatile, ideal for numerous installments and have a lengthy record.

Pros- Rubber roofing systems are relatively low-cost, easy to repair and set up. They are available in large sheets to lessen the variety of area seams, and there is quite bit of versatility in the membrane layer.

Disadvantages- Field seams on these roof coverings are not as strong as Thermoplastic roofing systems. Flashings and roof edges tend to wear out quicker compared to the rest of the roof. Shrinking over long periods could be dramatic in some applications.

Profits- Can be an excellent investment for a building proprietor, but all the circumstances of an offered SKYWAYSROOFING plastic roofing is packed with essential features installment has to be very carefully evaluated. And good handiwork on the set up is essential.

Some business refer to them as "re-plys", as you are essentially adding a ply to the existing roof surface. If an existing roof is experiencing leakages however has actually not advanced to the factor of straight-out failing, them might be good prospects for this option.

Pros- Can be incredibly cost effective, particularly on roofing systems that have a lot of estimates and rooftop HVAC devices. The material is pure white, which in some cases (particularly on metal roof coverings) can significantly lower A/C cooling costs. As this is considered to be roof repair services rather than a new roof, there are tax benefits too.

Cons- The existing roof should still be in somewhat decent problem. Some makers do not service warranty this product if there is ANY ponding water on the roof.

Bottom line- This service might save a building owner a great deal of loan, if the existing roof remains in sufficient condition to accept the covering. Outstanding solution for steel roofings particularly.

As you can see, there are many different remedies to your level roofing requirements. It is important however to pick a roofer who will certainly recommend the best system for your certain roof and conditions, and not the very best remedy for his budget. Be sure you recognize why a roofer is suggesting a particular system for your job, and which system will be the most effective investment for you.


Disadvantages- Being single ply, they are prone to discarded cigarettes, sharp things went down on the membrane, and busted glass from bottles tossed on roof (this happens a LOT) I normally dissuade consumers from installing these kinds of systems if the roof has a lot of foot web traffic or is conveniently available to unapproved personnel. These roof coverings are so challenging in truth, that a lot of insurance policy firms will not even acknowledge hail damages as they do on various other roofings (I have personally seen modified roofs definitely pummeled with hail storm and come out completely undamaged).

Disadvantages- Field joints on these roofings are not as solid as Thermoplastic roofing systems. Flashings and roof edges often tend to put on out much more swiftly compared to the rest of the roof. As this is considered to be roof repair services instead compared to a brand-new roof, there are tax obligation benefits.
