Roof leaks even after it has stopped raining.

On our way to an emergency repair.building manager called us with roof leaks taking place all over the multi-unit building 

roof leaks,visible all over the place.
 

another badly affected unit,tenants needles to say are very concerned about the condition of the roof covering their respective units.in this case the water dripped so heavily the damage extended onto the rest of the ceiling.

the following morning!
this roof holds so much water,all the drains were clogged up with debri,water was definitely stressing the faulty seams

after several hours of sweeping water away.preparation is very important.otherwise the material will not stick.
the surface must be dry and primed.
 

existing roof has definitely seen better years.

most defects or openings are found after a diligent search,this is where experience and know how play their role.

this seams are stressed because of the low area where they're located.
water will pond,the drastic change in temperature will split the seams open.

standing water will travel underneath the roofing material.and the leak will show up somewhere completely different.

this is where regular periodic maintenance will save the day.
Nothing will last forever,the same applies to your roof.
all these roof leaks could have been prevented

We applied permanent patches all over these openings.
the surface was dried,and the openings torched down,primed and sealed.

This roof needs to be coated with a fibered reflective coating,until it is replaced.

taking advantage of the weather.definitely bound to change.
notice all the patches applied over the defective seams,no wonder why the leaks appeared in different areas of the building.

Every roof protrusion could be a potential roof leak,the seal at the base of this pipe needs to be sealed.

a roof coating will be suggested,since we are only here as an emergency,but also a replacement should be kept in mind.

we concentrated on all the open seams above the affected portions of the building

we have to comeback before the snow comes down,a preventative maintenance plan will be suggested.
and try to stop the roof leaks before they even happen.roof maintenance.its the keyword.

we are glad we could fix this problems.building manager and homeowners alike.call us for all your roof issues.

multi-unit building roof evaluation and emergency repair

Building manager called us.head engineer was checking the roof and found large openings on the roof's membrane,next to large drain.

Torched down a permanent patch over the affected area,initially the loose portion is fused together.
Primed and sealed.

The roof drain happens to be the lowest point.immediately we checked the rest of the drains and found openings on three more.some more severe than others

Very large roof.heavy rains are expected tonight,this would have been disastrous .one roof drain alone handles massive amounts of water.

Other visible openings were spotted right away a few feet away from another drain

Keyword:Roof maintenance.
Nothig lasts forever

We visually check the entire roof and perimeter.These are small overlooked issues but bound to give you big problems,we will notify the property manager.

We have to comeback in better weather,to prime and paint all these vents the rust will discolor the roofing membrane and potentially start damage.

Wind damage.extra fasteners will be applied on these wind facing wall

Water ponds next to skylight all these seams have to be reinforced because this will turn to ice and split the seams open.this will be covered with snow making it next to impossible to detect

Open seams fused together.primer was applied and a permanent patch torched over it.

The seams around the roofs drains are expected to suffer the most wear and tear.
These need to be probed to make sure they're sound.

Large HVAC unit,the curb was thoroughly checked.another roof drain sits a few feet away.

This one required two patches.we can not stress enough the importance of preventative maintenance.

Different view.notice the granular loss on the existing material due to the large volume of water these drains handle during a heavy downpour like the one expected tonight.Please give us a call for all your roofing needs
We give you peace of mind and wellake sure your roof will be watertight.

It will be pouring tonight,we are glad we got those openings permanently sealed.call us if you are in need of our services.this building manager was pleased with the results and he wont be getting any phone calls from angry tenants

large water leak over hallway

Property manager called us with a problem.
It goes without saying. We had to act quickly since rains were expected overnight.

We found a very old and deteriorated flat roof above the end of the hallway

A solution to the problem was decided immediately.
No patches!

A permanent solution.modified bitumen will be torched down over the existing .this happened to be the original roof,only one thin layer of asphalt and tar paper.

Small roof but it hold a a lot of water
The only drain,its the scupper box,located on the corner.

Quite a few small "boxes" or curbs these had to be flashed also to complete the job.time was of the essence.
Since heavy rains were expected overnight

The flashing on the wall its wide open and a downspout from a high roof dumps water on the left (we moved it to have acces to the wall)

Small roof,but time consuming with all the detail work.
New modified has been applied 

New roof its been applied,watertight tonight.
A permanent solution to a long postponed problem.
Property managers dont forget to call us and homeowners as well.
