More than just a roof.

 

Roofing comprises many many different things to get a working system for your house.

 

Shingled roofs:

I repair existing shingled roofs and also replace them if needed. I will honestly tell you what you need.

A Shingled roof is a roofing structure with more than a 9 degree slope in it. Less than this requires a completely different technology( a flat roof technology ). the shingles today are mostly fiberglass based and come with a limited lifetime warranty. they will probably last about 30 years from what i see from having installed them for more than 20 years.i have installed hundreds of shingled roofs from each manufacturer of these types of shingles. there are other MATERIALS to use, as in the picture above, which is a synthetic slate ( recycled plastic ) which comes with a 50 year warranty and will last much longer. I have installed cedar roofs, slate roofs and other types as well and am happy to discuss options with you. I have also with my own two hands, installed about 2,000 skylights and have now seen it all and can now fix it all. this includes all the carpentry to frame in new skylights as well as all the insulation and drywall work.

It would be true to say that in my years of doing this there were years where i repaired on average about $200,000 of new shingled roofs done by others. sadly in the next two weeks i will replace two shingled roofs that are less than two years old. i will throw the current roof, very nice people have paid for, in the garbage, due to leaks and misapplications of standard technologies.they can't be fixed or repaired and have to be replaced. i usually can fix what you have - if the materials are not to old.

Flat Roofs:

I fix flat roof and replace them as well. Flat roofs are the most problematic roofs because of the misapplication of standard practices ( this means they are easy to cheat on because not all the proper four layers are installed and  if they are, then they are installed poorly at times ). Shingled roofs are two layers thick thus half the expense.

NOTE: Due to the lack of ability to insulate under the flat roofs from inside a home without causing lots of drywall damage I find myself putting in lots of insulation under these roofs because when they are open the insulation is easy to install without causing any interior damage. 20% of the flat roofs I do have NO insulation in them!

A flat roof is a roofing structure with less than a nine degree slope in it.  The problems with flat roofs is that in our winters there is always one inch of water that sits on the roof and this has one inch of ice on top of it and then a layer of snow to top it  all off. This means that the roof has to be built to withstand puddling and hence must be a completely sealed membrane. think in terms of a swimming pool liner. 100% waterproof.  This is accomplished on most residential applications with a four layer thick torch welded membrane ( this means you melt pieces together  to make a fully waterproof membrane - see the photo above ).

To build a residential and in some cases a commercial flat roof, one tends to remove all the old layers of the old roofs. These layers are sometimes wet inside and trap water in them. This trapped water then turns to steam wrecking the newly installed roof   etc... So we almost always remove the old layers. Once any rotten wood is repaired, we install a fireproofing layer made of a fiberglass material, then a torch safe fiberglass board is installed and then we torch weld two layers of a thick rubber membrane ( 'modified bitumen' is the technical term - which means modified tar. It is modified into rolls with polyester layers in it. A picture of it is above ). This makes the four layers.  There are other types of flat roofs and most of them suck badly. Commercial roofs are usually 'tar and gravel' as they are cheaper on bigger projects.  Skylights on flat roofs are perfectly safe with the only stipulation being that they have to be installed high up off the roof. Higher than any puddling is possible. Usually 6'' is enough.  A common mistake is a shingled roof skylight installed into a flat roof.  I  fix one a week like this.  A fancy application is the two nice velux skylights installed above sloped away from any direct sunlight and glass to keep it quiet in a bedroom.

Please note in the photo above the little black lines.  This is evidence the roof has been torch welded together ( torch welding means: applying a flame to weld the flat roofing materials together ). The black lines are called 'bleeds' . This means and shows that two pieces of the membrane have been fully sealed and make inspection for waterproofness  easy.  All you need to see is the black lines to see that the melting of the individual pieces has occurred and thus all pieces have become one and hence fully waterproof.

Flat roofs are where lots of problems occur  because the wood is frequently rotten under them and/or they have no insulation in them as noted above and very often too many layers  causing the rafter to sag which causes unwanted puddles on the roof. All fixable and sometimes a surprise mid job. Ask me about this if you need further data.
