If your home or building has a flat roof, then you know that water is its major nemesis and leaks must be aggressively addressed with top-quality flat roof repair materials and methods. We explore whether DIY flat roof repair is something you want to attempt or if it makes more sense to hire a professional flat roofing specialist.

These flat roof repair techniques can be used on the most common flat roof materials:

  • EPDM, aka Rubber
  • Modified bitumen
  • BUR (Built up roofing), aka tar and gravel

PVC roof repair
Note: If you happen to have a PVC or TPO roof leak, such as a leaky seam or a hole/puncture caused by a fallen tree branch or an accidental cut, then you will need to find a qualified specialist equipped with all the necessary tools and supplies; a roll of appropriate membrane and a heat air gun. Look for a company specializing in PVC or TPO.

Locating a Flat Roof Leak

While finding a leak in a flat roof is easier than on a steep-sloped, shingled roof, leaks can still be deceiving. Where water enters your interior space might not be exactly where the leak is, because any water that penetrates a roofing membrane can travel for some distance until it finds a seam in the sub-roof or sheathing and seeps inside.

These steps will allow you to isolate the source of the leak if it isn’t readily evident when you inspect the roof.

  • From inside, measure the distance from where the leak is visible to the two nearest walls.
  • Use those measurements on the rooftop to create a starting point for your search.
  • Most flat roofs are very slightly sloped to facilitate runoff, so explore from the point of the water’s entrance up the slope, since water runs downhill.
  • Look for punctures, popping screws, rips, worn spots, seam separations, blisters and other imperfections in the membrane.
  • If no damage is found in the membrane, examine nearby vent pipe boots, flashing, caulk around vents and similar structures for damage.
  • When you still cannot locate the leak, call a professional flat roof contractor for assistance and repair.

Caution: It’s always smart to respect ladders and heights, so proceed with extreme care! If you can’t access the roof from inside, use a quality ladder rated for more than your weight, and have a strong adult hold the ladder steady for you. If the roof is icy, even greater precaution is required, or a pro should be called in.

Repairing a Minor Flat Roof Issue

Warranties for flat roofs can range from 5 to 20 years. If your roof is under warranty, call the contractor that installed it to make the repair. Even if the warranty is prorated for the age of the roof, you might still save money with pro repair. You’ll have the confidence the job was done correctly and have recourse if it wasn’t.

If the warranty is up, then you can attempt the repair yourself. If it holds, you’ve saved money; If not, you won’t make it worse with the methods we suggest, and a flat roof contractor can repair it.

Rubber Roof Repair Tools:

  • Roofing Seams Probing tool
  • Roofing Hand Roller tool
  • Roofing Membrane Cleaner
  • EPDM rubber glue
  • EPDM peel and stick roofing tape
  • Appropriate Ladder with ladder stabilizer
  • Paint brush used to spread the glue
  • Bucket of warm water and clean towels

Other tools you may need will depend on the roofing system in question and a specific problem you’re repairing. The common tools used for repairs include a utility knife ($3-$6), tube of roofing sealant or cement ($4-$6), a caulk gun ($5-$20), a 2” putty knife or brush ($1-$4) and peel & stick flashing ($35-$125/size of the roll).

EPDM repairs require a few specialty items including EPDM glue ($12/tube or $40/gallon), weathered membrane cleaner for older roofs ($12/quart or $25/gallon) and EPDM/TPO primer ($15/quart or $40/gallon).

Evolution of Modern Home Design and Decor by Millennials

Ever wonder what Millennial homeowners or home buyers want in terms of exterior and interior home design, living space layout, interior decor, and other architectural elements of a house? Knowing this can help inform your remodeling choices and ultimately affect desirability and salability of your home later.

Read on to learn how to please a millennial with your thoughtful choices of home improvements and remodeling upgrades.

Before we get started – Who are these Millennials anyway?

Millennials – those people born between 1982 and 2004 – are gradually coming of age and becoming the new first-time home buyers these days. It may be hard to believe, but the oldest Millennials are now in their early thirties! Of course, whenever a new generation takes over the mantle of first-time home buyer, the housing industry reacts; building and design trends become driven by that generation’s unique preoccupations and interests. (Remember floral wallpaper?)

Even though there’s been a lot of buzz in the media about Millennials moving back in with their parents due to economic pressure and enormous student loan debt, they still overwhelmingly want to own homes when they can afford to. Perhaps more surprisingly, they also represent a significant portion of the home buying market. How significant? Try 35%!

That’s enough to make home builders and home designers pay attention. After all, even if they are currently buying older, cheaper, and smaller homes than their wealthier elders, those same Millennials will be the second- and third-time home buyers of the future – and they’re going to want to buy homes that make them feel comfortable.

In fact, in a survey conducted by Better Homes & Gardens, 63% of Millennial survey-takers said that having a customized home suited to their tastes was a top priority. Consequently, anyone trying to sell a house in 2017 probably ought to know what qualities Millennials are looking for in a new home.
