Repair Or Replace Your Roof Before Installing Solar PV PhotoVoltaic Panels

Blockquote description goes here…

There is a mad rush in Hawaii to put up solar PV panels before the 65% Federal and State tax credits (possibly) go away. With the bruising political fights raging over deficit reduction there is no guarantee that these tax credits will go on forever. There is no better time then now to make that plunge.

But in your race towards energy independence don’t forget to consider replacing (or repairing) the roof underneath your new solar panels. That’s where LeakMaster Roofing comes in. They are specialists in integrating your new solar panels–both hot water and PhotoVoltaic panels– into your roof system. Even if your existing roof is in fairly good condition, there are still things that you can do to preserve your existing roof before they are covered up with panels. Don’t forget, once the panels are fastened down tight to the roof deck for the next 20-plus years, your access to your roof itself becomes problematic if you should get a leak. It is much less expensive to repair or replace your roof BEFORE you install your solar.

Here are some possible solutions that can fit any budget:

  1. SIMPLY REPAIR YOUR EXISTING ROOF. This is true especially if you have an asphalt shingle type of roof. Quite often these roofs have a lot of life left in them and they don’t have to be replaced. LeakMaster can usually inspect and repair these roofs before the solar installation and then come back after the PV contractors are done and waterproof all the new penetrations into the roof deck. Depending on the condition of your shingles LeakMaster can warrant against leaks for up to 7 years.

  1. PUT A PROTECTIVE WATERPROOF COATING UNDERNEATH THE PANELS. If it’s on a flat roof you should at least waterproof the areas directly underneath the panels while there is easy access. Later on, when your budget allows, you can extend your protective coating to the rest of the flat roof. That is the beauty of roof coatings as opposed to old fashioned asphalt roofing–you can do limited areas now and then tie them all together later when they start to deteriorate. LeakMaster’s Ceramic Titanium coatings block 100% of the sun’s UV rays so your old roof is preserved. You never have to tear off the old roof, just put on a new top coat every 7 to 15 years.


If you have a sloped roof, LeakMaster installs all major systems including shake, shingle, tile, metal and asphalt. After the solar contractors are finished LeakMaster will come back and waterproof all your roof penetrations for no extra charge.

If you have a flat roof LeakMaster can install either a fabric re-enforced coating, such as Hawaiian Sunguard, or a Silicone based coating which may qualify for a 10, 15 or even 20 year Manufacturer Labor and Material Warranty, depending on your roof.

For commercial roofs, you may want to consider a heavy duty Single Ply system, such as Duro-Last, which has the “Worlds Best Warranty.” That’s because they insure you against any damage to the contents in your property due to a faulty roof.
