Boyd Construction Co Inc has been fitting new flat roofs in the Washington DC area for over 81 years. As you can imagine they are a great reliable source to gain some insight and reliable information on just what you would need for your Washington DC flat roof.
Most modern flat roofs have an average lifespan of 20 years, so in a lifetime you would only have to replace it maybe 3 times.
Here are the most commonly used and installed flat roof systems:
Torch on felt roofingTorch on felt – 3 layers of felt are melt welded together with a large blowlamp or torch from where it derives the name torch on. Make sure any roofing contractor carries the correct insurance to work with hot flame.
EPDM rubber roof – Firestone or similar
These have stormed the market since being introduced a few years ago in the U.K. A rubber roof can be often installed in one complete layer without the need for joins depending on size, which is often an attractive prospect. It is also extremely light weight, elastic and tough, so it lends itself to many situations. Mostly rubber roofs are glued down to the decking ( wooden substrate ) so if you had a felt roof previously the timber deck may need replacing depending on the system or glue used.
Fibreglass GRP flat roof
These have been around in the UK for well over 20 years but in small numbers, I first came across GRP many years ago when I was asked to supply a no-flame solution for a very awkward roof. Fibreglass roofs have suffered from a bad reputation in the past due to ignorance and faulty installation. A common mistake was using standard boat resins that couldn’t expand or contract properly, or laying fibreglass onto chipboard or smooth plywood. These days’ modern resins and correct installation has helped fibreglass become a real contender for a top flight flat roof. Normally laid in a one, or sometimes a two layer jointless finish with factory made trims and coloured to literally any colour.
