No funds for replacement? Consider restoration.
Roof restoration is the process of using highly-engineered coating products to "restore" an existing roof deck to a like-new condition. It is used on PVC, TPO, EPDM, MOD-BIT, built-up, and even some SPF roofing systems. When you need a new roof, you typically have two, related options. Option 1: Simply cover up the existing roof with a new roof. Option 2: Tear off the existing roof(s) and then install a new roof. As you might well imagine, Option 2, the tear-off option, is significantly more expensive than Option 1, which does not require a tear-off. What determines whether or not a tear-off is required? Generally speaking, if there are already two or more existing roofing systems installed, local codes typically require (double-check this with your local people) that before a new roofing system is installed, all of the previous roofing systems must be removed down to the roof deck. This is a messy, noisy, and very expensive process. It also adds a tremendous amount of roofing debris to the local landfill. But this is where a roof restoration system comes in. A roof that typically would require a tear-off, but is in otherwise 'restorable' condition, might benefit from restoration. This would mean no tear-off! No tear-off would mean virtually no mess, a lot less noise, and could save you thousands of dollars (depending on the size of the roof.)
Fluid-applied cool roof coating systems are seamless and can solve roof leaks on almost any type of roofing material.The reflective surface of a roof coating system can extend the life of your roof keeping the surface cool and providing protection from the sun’s damaging infrared and UV rays. Cool roof coatings can add 10 to 25 years to the life of your roof and reduce the amount of disposed roofing materials that end up in landfills. Field studies have shown that cool roof coatings can lower your rooftop temperatures and significantly reduce your air conditioning bills.
