Common mistakes by roofers – they install shingles on a flat roof. So many so-called roofers have no idea where to draw the line between what is suppose to be the flat roof and what is a pitched roof. The homeowner will pay for that inexperience. Shingles on a low pitch roof like this one are just not right.

Installing shingles on a low sloping roof

This is a very common mistake. If there is a skylight, that will increase the chances of a leak. What compounded the problem on this roof is that there was a skylight. The skylight will cause more leaks due to the low pitch of the roof.

Roofing Cement – Tar

Tar – tar – tar. Why so many people believe that tar will solve a roof leak. The tar that was smeared around this skylight just made it worse. When you use tar you have to be careful not to cover some flashing areas like the bottom part of this skylight. The pitch of this roof is too low to even try to make a repair. The best way is to strip and remove the shingles and install a rubber roof.

The pitch of this roof is to low to even try to make a repair.

Where Roofs meet

When two roofs meet, there is a potential to have a problem, but when you add a third element to this (skylight), then you asking for a leak. The design of this roof is also wrong. When you see a corner of a skylight flashing in a valley, you know that will cause a leak.

    The roof at my work building has had some leak problems lately whenever it rains really hard. We’ve already invested a lot of time into making the necessary fixes. I really liked this post though because of the focus on maintenance. I like the advice to get regular inspections to prevent problems before they arise, which is exactly what I am going to start doing!
